Prenez d'abord connaissance des cinq documents suivants : Victor HUGO Lettre Lord Palmerston ( Actes et paroles II, 1875) . [Fortement impressionné, enfant, par la vision d’un condamné conduit à l’échafaud sur une place de Burgos puis, à l’adolescence, par les préparatifs du bourreau dressant la guillotine en place de Grève, Victor Hugo fut toute sa vie un adversaire résolu de la peine de mort. Analysis Template Archives? En exil à Guernesey, il assiste en 1854 à l'exécution de John-Charles Tapner, condamné à mort pour assassinat, et fait part aussitôt de son indignation à Lord Palmerston, alors secrétaire à l'Intérieur.] Marine-Terrace, 11 février 1854.

Il avait le front haut et le pas ferme ; il était pâle ; le cercle rouge de l'insomnie entourait ses yeux. Analysis - Microsoft? Le mois qui venait de s'écouler venait de le vieillir de vingt années.
Cet homme de trente ans en paraissait cinquante. Sample Asset Purchase Agreement - 10+? Un bonnet de coton blanc profondément enfoncé sur la tête et relevé sur le front, - dit un témoin oculaire, - vêtu de la redingote brune qu'il portait aux débats, et chaussé de vieilles pantoufles , il a fait le tour d'une partie du jardin dans une allée exprès. Template - Microsoft Templates? Les bordiers, le shérif, le lieutenant-shérif, le procureur de la reine, le greffier et le sergent de la reine l'entouraient. A Title Page Research Writing? Il avait les mains liées ; mal, comme vous allez voir. Template - Microsoft Excel Templates? Pourtant, selon l'usage anglais, pendant que les mains étaient croisées par les liens sur la poitrine, une corde rattachait les coudes derrière le dos. Make A Title For A Research Paper Writing? Il marchait l'œil fixé sur le gibet. Templates? Tout en marchant il disait à voix haute : Ah mes pauvres enfants ! A côté de lui, le chapelain Bouwerie, qui avait refusé de signer la demande en grâce, pleurait. L'allée sablée menait à l'échelle. Sample Of Employment Offer? Le nœud pendait. Template? Tapner a monté. Purple Simple Invitation Letter Png And? Le bourreau d'en bas tremblait ; les bourreaux d'en bas sont quelquefois émus.
Tapner s'est mis lui-même sous le nœud coulant et y a passé son cou, et, comme il avait les mains peu attachées, voyant que le bourreau, tout égaré, s'y prenait mal, il l'a aidé. Template Archives Excel? Puis, comme s'il pressentait ce qui allait suivre, - dit le même témoin, - il a dit : Liez-moi donc mieux les mains. Archives - Hnm Global Logistics? - C'est inutile, a répondu le bourreau. Analysis - Microsoft? Tapner étant ainsi debout dans le nœud coulant, les pieds sur la trappe, le bourreau a rabattu le bonnet sur son visage, et l'on n'a plus vu de cette face pâle qu'une bouche qui priait. July 2012? La trappe, prête à s'ouvrir sous lui, avait environ deux pieds carrés. - Microsoft Templates? Après quelques secondes, le temps de se retourner, l'homme des hautes œuvres a pressé le ressort de la trappe. News Archives Logistics? Un trou s'est fait sous le condamné, il y est tombé brusquement, la corde s'est tendue, le corps a tourné, on Template - Microsoft Excel Templates a cru l'homme mort. Corporate Communication ( Organizational Communications)? On pensa, dit le témoin, que Tapner avait été tué raide par la rupture de la moelle épinière. Analysis Template Archives - Microsoft Excel? Il était tombé de quatre pieds de haut, et de tout son poids, et c'était un homme de haute taille ; et le témoin ajoute : Ce soulagement des cœurs oppressés ne dura pas deux minutes. Sample Of Employment Letter? Tout à coup, l'homme, pas encore cadavre et déjà spectre, a remué ; les jambes se sont élevées et abaissées l'une après l'autre comme si elles essayaient de monter des marches dans le vide, ce qu'on entrevoyait de la face est devenu horrible, les mains, presque déliées, s'éloignaient et se rapprochaient comme pour demander assistance, dit le témoin.
Le lien des coudes s'était rompu à la secousse de la chute. Analysis Archives? Dans ces convulsions, la corde s'est mise à osciller, les coudes du misérable ont heurté le bord de la trappe, les mains s'y sont cramponnées, le genou droit s'y est appuyé, le corps s'est soulevé, et le pendu s'est penché sur la foule. - 10+ In Word, Pdf? Il est retombé, puis a recommencé. Archives - Microsoft Templates? Deux fois, dit le témoin. ( Organizational Structure,?

Cela durait trop, à ce qu'il paraît. - Microsoft Excel Templates? Il a fallu finir. Simple Letter? Le bourreau, qui était descendu, est remonté, et a fait, je cite toujours le témoin oculaire, lâcher prise au patient. - Microsoft? La corde avait dévié ; elle était sous le menton ; le bourreau l'a remise sous l'oreille : après quoi il a pressé les épaules. Logistics? Le bourreau et le spectre ont lutté un moment ; le bourreau a vaincu.
Puis cet infortuné, condamné lui-même, s'est précipité dans le trou où pendait Tapner, lui a étreint les deux genoux et s'est suspendu à ses pieds. Analysis Template Archives Excel? La corde s'est balancée à un moment, portant le patient et le bourreau, le crime et la loi. Logistics? Enfin, le bourreau a lui-même lâché prise . Template? C'était fait. News - Hnm Logistics? L'homme était mort. Vous le voyez, monsieur, les choses se sont bien passées. Excel? Cela a été complet. Letter?

La ville étant bâtie en amphithéâtre, on Corporate Communication ( Organizational Structure, Communications) voyait cela de toutes les fenêtres. Template Templates? Les regards plongeaient dans le jardin. La foule criait : shame ! shame ! shame ! Des femmes sont tombées évanouies.
Pendant ce temps-là, Fouquet, le gracié de 1851, se repent. Sample Of Employment | Docoments? Le bourreau a fait de Tapner un cadavre; la clémence a refait de Fouquet un homme. Template Templates? Dernier détail. How To For A Research Writing?

Cinquante mille francs ! quand on Offer | Docoments y pense, ce n’est pas trop cher ; il y a beaucoup de détails dans cette chose-là.
On voit l’hiver, à Londres, dans de certains quartiers, des groupes d’êtres pelotonnés dans les angles des rues, au coin de portes, passant ainsi les jours et les nuits, mouillés, affamés, glacés, sans abri, sans vêtements et sans chaussures, sous le givre et sous la pluie. Analysis Excel? Ces êtres sont des vieillards, des enfants et des femmes ; presque tous irlandais ; comme vous, monsieur. ( Organizational Structure, Communications)?

C’est ainsi que cela doit se passer. Template - Microsoft Excel? Un nommé Tawel a été pendu récemment par le bourreau de Londres, qu’une relation que j’ai sous les yeux qualifie ainsi : Le maître des exécuteurs, celui qui s’est acquis une célébrité sans rivale dans sa peu enviable profession.
Eh bien, ce qui est arrivé à Tapner était arrivé à Tawel. News Archives? On aurait tort de dire qu’aucune précaution n’avait été prise pour Tapner. Analysis Template Archives Templates? Le jeudi 9, quelques zélés de la peine capitale avaient visité la potence déjà toute prête dans le jardin. Png And Vector For Free?

Elle s’est évanouie, deux fois en lui disant adieu ; le second évanouissement a duré une demi-heure ; on Template - Microsoft l’a crue morte. News Archives Global Logistics? Voilà, monsieur, j’y insiste, de quelle façon est mort Tapner.
Un fait que je ne puis vous taire, c’est l’unanimité de la presse locale sur ce point : Il n’y aura plus d’exécution à mort dans ce pays, l’échafaud n’y sera plus toléré. - Microsoft Excel? La Chronique de Jersey du 11 février ajoute : Le supplice a été plus atroce que le crime. Archives Logistics? J’ai peur que, sans le vouloir, vous n’ayez aboli la peine de mort à Guernesey. Analysis Template - Microsoft Templates? Je livre en outre à vos réflexions ce passage d’une lettre que m’écrit un des principaux habitants de l’île : L’indignation était au comble, et si tous avaient pu voir ce qui se passait sous le gibet, quelque chose de sérieux serait arrivé, on Agreement Examples Pdf aurait tâché de sauver celui qu’on torturait.

utexas dissertation Daniel Gregory Lessin(1). Evolved Virtual Creatures as Content: Increasing Behavioral and Morphological Complexity. The University of Texas at Austin, Department of Computer Science(1). Report# TR-15-01 (dissertation). January 3rd, 2015.
Throughout history, creature-based content has been a highly valued source of entertainment. With the introduction of evolved virtual creatures (or EVCs) by Template Templates Karl Sims in 1994, a new source of creature content became available. Despite their immediate appeal, however, EVCs still lag far behind their natural counterparts: Neither their morphology nor their behavior is sufficiently complex. This dissertation presents three contributions to address this problem. First, the ESP system, which combines a human-designed syllabus with encapsulation and conflict-resolution mechanisms, is used to approximately double the state of the Edol 533: July 2012, art in behavioral complexity for evolved virtual creatures. Second, an extension to ESP is presented that allows full morphological adaptation to continue beyond the initial skill. It produces both a greater variety of solutions and solutions with higher fitness. Third, a muscle-drive system is demonstrated to embody a significant degree of Analysis Template Archives - Microsoft, physical intelligence.
It increases morphological complexity and Corporate Communication ( Organizational Structure,, reduces demands on the brain, thus freeing resources for more complex behaviors. Together, these contributions bring evolved virtual creatures, in both action and form, a significant step closer to matching the entertainment value of Template Archives Excel Templates, creatures from the real world.

Intelligent organisms do not simply perform one task, but exhibit multiple distinct modes of Analysis Excel, behavior. For instance, humans can swim, climb, write, solve problems, and play sports. To be fully autonomous and robust, it would be advantageous for Asset Purchase - 10+ Pdf, artificial agents, both in physical and virtual worlds, to exhibit a similar diversity of behaviors. This dissertation develops methods for discovering such behavior automatically using multiobjective neuroevolution. First, sensors are designed to allow multiple different interpretations of objects in the environment (such as predator or prey). Second, evolving networks are given ways of representing multiple policies explicitly via modular architectures.
Third, the set of objectives is Analysis Template Excel Templates dynamically adjusted in order to lead the population towards the most promising areas of the Invitation Download, search space. These methods are evaluated in five domains that provide examples of three different types of task divisions. Isolated tasks are separate from each other, but a single agent must solve each of them.

TEXPLORE: Temporal Difference Reinforcement Learning for Robots and Time-Constrained Domains. The University of Texas at Template Archives Excel, Austin, Department of Computer Science(1). Report# TR-12-32 (dissertation). December 6th, 2012. 281 pages. Robots have the potential to solve many problems in society, because of their ability to work in dangerous places doing necessary jobs that no one wants or is able to do. One barrier to their widespread deployment is that they are mainly limited to tasks where it is possible to hand-program behaviors for every situation that may be encountered.
For robots to Offer | Docoments Ojazlink meet their potential, they need methods that enable them to learn and adapt to novel situations that they were not programmed for. Archives Excel. Reinforcement learning (RL) is a paradigm for learning sequential decision making processes that could solve the problems of Purple Letter Png And Download, learning and adaptation on robots. This thesis identifies four key challenges that must be addressed for an RL algorithm to be practical for robotic control tasks. These RL for Excel Templates, Robotics Challenges are: 1) it must learn in very few samples; 2) it must learn in domains with continuous state features; 3) it must handle sensor and/or actuator delays; and Invitation For Free Download, 4) it should continually take actions in Excel real-time. This thesis focuses on addressing all four of these challenges. In particular, this thesis is focused on time-constrained domains where the first challenge is For Free critically important.
In these domains, the agent?s lifetime is not long enough for it to Analysis Archives Excel explore the domain thoroughly, and it must learn in Corporate Communication Structure, Communications) very few samples. Although existing RL algorithms successfully address one or more of the RL for Robotics Challenges, no prior algorithm addresses all four of them. To fill this gap, this thesis introduces TEXPLORE, the first algorithm to address all four challenges. TEXPLORE is a model-based RL method that learns a random forest model of the domain which generalizes dynamics to unseen states. Each tree in the random forest model represents a hypothesis of the Analysis Archives - Microsoft Excel, domain?s true dynamics, and the agent uses these hypotheses to explores states that are promising for the final policy, while ignoring states that do not appear promising. With sample-based planning and a novel parallel architecture, TEXPLORE can select actions continually in real-time whenever necessary.
We empirically evaluate each component of TEXPLORE in comparison with other state-of-the-art approaches. In addition, we present modifications of Asset In Word,, TEXPLORE?s exploration mechanism for Analysis Template Archives, different types of domains. The key result of this thesis is a demonstration of TEXPLORE learning to control the Communications), velocity of an autonomous vehicle on-line, in real-time, while running on-board the Template - Microsoft Excel Templates, robot. After controlling the vehicle for only two minutes, TEXPLORE is able to learn to Edol move the pedals of the Template Archives - Microsoft Excel, vehicle to drive at the desired velocities. The work presented in Purple Simple Png And Vector For Free Download this thesis represents an important step towards applying RL to robotics and enabling robots to perform more tasks in society. By enabling robots to learn in Template Archives - Microsoft Excel few actions while acting on-line in Simple Letter Png And Vector For Free real-time on robots with continuous state and actuator delays, TEXPLORE significantly broadens the applicability of RL to robots.
W. Analysis Archives Templates. Bradley Knox(1). Learning from Human-Generated Reward. The University of Texas at Austin, Department of Computer Science(1). Report# TR-12-22 (dissertation). September 1st, 2012. 263 pages. News Global Logistics. Robots and other computational agents are increasingly becoming part of our daily lives. They will need to be able to Analysis - Microsoft Excel Templates learn to perform new tasks, adapt to novel situations, and understand what is wanted by their human users, most of whom will not have programming skills. To achieve these ends, agents must learn from 533: July 2012 humans using methods of communication that are naturally accessible to everyone. Archives - Microsoft Excel. This thesis presents and formalizes interactive shaping, one such teaching method, where agents learn from real-valued reward signals that are generated by a human trainer.
In interactive shaping, a human trainer observes an agent behaving in a task environment and Global, delivers feedback signals. These signals are mapped to Analysis numeric values, which are used by Invitation Png And Vector For Free Download the agent to specify correct behavior. A solution to the problem of Analysis Template - Microsoft, interactive shaping maps human reward to Corporate ( Organizational Structure, Communications) some objective such that maximizing that objective generally leads to the behavior that the trainer desires. Interactive shaping addresses the aforementioned needs of real-world agents. Template Archives - Microsoft Excel Templates. This teaching method allows human users to quickly teach agents the specific behaviors that they desire. Further, humans can shape agents without needing programming skills or even detailed knowledge of how to perform the task themselves. In contrast, algorithms that learn autonomously from only a pre-programmed evaluative signal often learn slowly, which is Sample - 10+ Examples unacceptable for some real-world tasks with real-world costs. Analysis Template Archives Excel Templates. These autonomous algorithms additionally have an inflexibly defined set of optimal behaviors, changeable only through additional programming. Through interactive shaping, human users can (1) specify and teach desired behavior and (2) share task knowledge when correct behavior is already indirectly specified by an objective function.
Additionally, computational agents that can be taught interactively by humans provide a unique opportunity to study how humans teach in a highly controlled setting, in which the Sample Purchase Agreement Examples, computer agent's behavior is parametrized. - Microsoft Templates. This thesis answers the following question. How and to what extent can agents harness the Vector, information contained in human-generated signals of reward to learn sequential decision-making tasks? The contributions of this thesis begin with an operational definition of the Template Excel, problem of interactive shaping. Next, I introduce the TAMER framework, one solution to the problem of interactive shaping, and describe and analyze algorithmic implementations of the framework within multiple domains. Sample Letter Ojazlink. This thesis also proposes and empirically examines algorithms for learning from Template - Microsoft Excel both human reward and a pre-programmed reward function within an MDP, demonstrating two techniques that consistently outperform learning from either feedback signal alone. Subsequently, the Purple For Free, thesis shifts its focus from the agent to the trainer, describing two psychological studies in which the trainer is manipulated by either changing their perceived role or by Excel Templates having the agent intentionally misbehave at specific times; we examine the effect of these manipulations on trainer behavior and the agent's learned task performance. Lastly, I return to the problem of interactive shaping, for Sample Purchase Agreement - 10+ Examples Pdf, which we examine a space of mappings from human reward to objective functions, where mappings differ by how much the agent discounts reward it expects to receive in the future.
Through this investigation, a deep relationship is identified between discounting, the level of Analysis Template Archives Excel Templates, positivity in Purple Vector For Free Download human reward, and training success. Specific constraints of human reward are identified (i.e., the positive circuits problem), as are strategies for overcoming these constraints, pointing towards interactive shaping methods that are more effective than the already successful TAMER framework.

The University of Texas at Communication Structure, Communications), Austin, Department of Computer Science(1). Report# TR-12-19 (dissertation). August 22nd, 2012. 256 pages. The problem of multiagent learning (or MAL) is concerned with the study of how agents can learn and adapt in the presence of other agents that are simultaneously adapting. The problem is often studied in the stylized settings provided by repeated matrix games.
The goal of Archives Excel, this thesis is to develop MAL algorithms for such a setting that achieve a new set of objectives which have not been previously achieved. Edol 533: July. The thesis makes three main contributions. The first main contribution proposes a novel MAL algorithm, called Convergence with Model Learning and Safety (or CMLeS), that is the first to achieve the following three objectives: (1) converges to Analysis Archives - Microsoft Templates following a Nash equilibrium joint-policy in self-play; (2) achieves close to the best response when interacting with a set of memory-bounded agents whose memory size is upper bounded by Corporate ( Organizational Structure, Communications) a known value; and (3) ensures an individual return that is very close to its security value when interacting with any other set of agents. The second main contribution proposes another novel MAL algorithm that models a significantly more complex class of agent behavior called Markovian agents, that subsumes the Analysis Archives Excel, class of memory-bounded agents. Called Joint Optimization against Markovian Agents (or Joma), it achieves the following two objectives: (1) achieves a joint-return very close to the social welfare maximizing joint-return when interacting with Markovian agents; (2) ensures an individual return that is very close to its security value when interacting with any other set of agents. Finally, the third main contribution shows how a key subroutine of Joma can be extended to solve a broader class of problems pertaining to Reinforcement Learning, called Structure Learning in factored state MDPs. All of the algorithms presented in this thesis are well backed with rigorous theoretical analysis, including an analysis on sample complexity wherever applicable, as well as representative empirical tests.

346 pages. Sequential decision making from experience, or reinforcement learning (RL), is a paradigm that is well-suited for agents seeking to optimize long-term gain as they carry out sensing, decision, and Edol July 2012, action in Analysis - Microsoft Excel an unknown environment. RL tasks are commonly formulated as Markov Decision Problems (MDPs). Learning in finite MDPs enjoys several desirable properties, such as convergence, sample-efficiency, and the ability to realize optimal behavior. Key to News achieving these properties is access to a perfect representation, under which the state and action sets of the Archives - Microsoft Templates, MDP can be enumerated. Unfortunately, RL tasks encountered in the real world commonly suffer from state aliasing, and nearly always they demand generalization. As a consequence, learning in practice invariably amounts to learning with imperfect representations. In this dissertation, we examine the effect of imperfect representations on different classes of learning methods, and introduce techniques to improve their practical performance. We make four main contributions.
First we introduce ``parameterized learning problems'', a novel experimental methodology facilitating the How To For A Research, systematic control of representational aspects such as state aliasing and generalization. Applying this methodology, we compare the class of on-line value function-based (VF) methods with the class of policy search (PS) methods. Results indicate clear patterns in the effects of representation on these classes of methods. Our second contribution is a deeper analysis of the limits imposed by representations on VF methods; specifically we provide a plausible explanation for the relatively poor performance of these methods on Tetris, the popular video game. The third major contribution of this dissertation is a formal study of the ``subset selection'' problem in multi-armed bandits. This problem, which directly affects the Template Archives Templates, sample-efficiency of several commonly-used PS methods, also finds application in areas as diverse as industrial engineering and on-line advertising. We present new algorithms for subset selection and bound their performance under different evaluation criteria. - 10+ Examples Pdf. Under a PAC setting, our sample complexity bounds indeed improve upon - Microsoft Excel existing ones. As its fourth contribution, this dissertation introduces two hybrid learning architectures for combining the strengths of Corporate Communications), VF and PS methods.
Under one architecture, these methods are applied in sequence; under the other, they are applied to separate components of a compound task. Template - Microsoft. We demonstrate the effectiveness of these methods on a complex simulation of robot soccer. In sum, this dissertation makes philosophical, analytical, and methodological contributions towards the Make Page Research Paper Writing, development of robust and automated learning methods for sequential decision making with imperfect representations.

153 pages. An intelligent agent operating in the real world needs to be fully aware of the surrounding environment to make the best decision possible at any given point of time. Template Archives - Microsoft Templates. There are many forms of input devices for a robot that gather real-time information of the Archives - Hnm Global Logistics, surroundings, such as video cameras, laser/sonar range finders, and GPS to name a few. In this thesis, a vision system for Templates, a mobile robot navigating through different illumination conditions is investigated. Many state-of-the-art object recognition algorithms employ methods running on grayscale images, because using color is Global difficult for several reasons: (a) The object-of-interest's true colors may not be recorded by Analysis Template - Microsoft Excel the camera hardware due to Letter | Docoments illumination artifacts, and (b) colors are often too ambiguous to be a robust visual descriptor of an object. In this dissertation, we address these two challenges and Template Archives Excel Templates, present new color-based vision algorithms for mobile robots that are robust and efficient. The first part of this dissertation focuses on the problem of color constancy for mobile robots under different lighting conditions. Specifically, We use a generate-and-test methodology to evaluate which simulated global illumination condition leads to the generated view that most closely matches what the robot actually sees. We assume the diagonal color model when generating views of the object of interest under previously unseen conditions. Sample Examples Pdf. In the second part of the dissertation, we present a vision framework for mobile robots that enables observation of illumination artifacts in a scene and reasoning about the Archives - Microsoft Templates, lighting conditions to achieve robust color-based object tracking.

Report# TR-11-29 (dissertation). June 29th, 2011. 186 pages.
Researchers and practitioners alike have long sought to integrate programming languages and databases. Analysis Archives - Microsoft Templates. Today's integration solutions focus on the data-types of the two domains, but today's programs lack transparency. A transparently persistent program operates over all objects in a uniform manner, regardless of whether those objects reside in memory or in a database. Transparency increases modularity and lowers the barrier of adoption in industry. Unfortunately, fully transparent programs perform so poorly that no one writes them. The goal of this dissertation is to increase the Sample Asset - 10+ In Word,, performance of these programs to make transparent persistence a viable programming paradigm. This dissertation contributes two novel techniques that integrate programming languages and databases. Our first contribution -- called query extraction -- is - Microsoft Excel Templates based purely on program analysis. Query extraction analyzes a transparent, object-oriented program that retrieves and filters collections of objects. Some of - Hnm Global, these objects may be persistent, in which case the program contains implicit queries of persistent data. Our interprocedural program analysis extracts these queries from the program, translates them to explicit queries, and transforms the Archives Excel Templates, transparent program into an equivalent one that contains the explicit queries.
Query extraction enables programmers to write programs in a familiar, modular style and to rely on the compiler to transform their program into Agreement Examples one that performs well. Our second contribution -- called RBI-DB+ -- is an Analysis Template - Microsoft Excel Templates extension of a new programming language construct called a batch block. A batch block provides a syntactic barrier around transparent code. It also provides a latency guarantee: If the batch block compiles, then the code that appears in it requires only one client-server communication trip. Researchers previously have proposed batch blocks for databases. However, batch blocks cannot be modularized or composed, and Edol July, database batch blocks do not permit programmers to modify persistent data. Analysis Archives Excel. We extend database batch blocks to address these concerns and formalize the results. Today's technologies integrate the Communication ( Organizational Structure,, data-types of programming languages and Analysis - Microsoft Excel Templates, databases, but they discourage programmers from Edol July 2012 using procedural abstraction. Our contributions restore procedural abstraction's use in enterprise applications, without sacrificing performance. Template Archives Excel Templates. We argue that industry should combine our contributions with data-type integration. The result would be a robust, practical integration of programming languages and databases.

In both settings, methods of adaptation can be divided into four general categories: i) identifying the most similar previously encountered market, ii) learning from the current market only, iii) learning from the current market but using previous experience to tune the learning algorithm, and iv) learning from both the current and previous markets. The first contribution of this dissertation is the introduction and experimental validation of a number of novel algorithms for market adaptation fitting these categories.
The second contribution is an exploration of the degree to which the quantity and nature of market experience impact the relative performance of Template Archives - Microsoft Excel Templates, methods from these categories.

March 17th, 2011. Corporate Communication ( Organizational. 147 pages. No current laboratory test can reliably identify patients with schizophrenia. Template - Microsoft Excel Templates. Instead, key symptoms are observed via language, including derailment, where patients cannot follow a coherent storyline, and delusions, where false beliefs are repeated as fact.
Brain processes underlying these and other symptoms remain unclear, and characterizing them would greatly enhance our understanding of schizophrenia. In this situation, computational models can be valuable tools to formulate testable hypotheses and to complement clinical research. This dissertation aims to capture the link between biology and schizophrenic symptoms using DISCERN, a connectionist model of Offer Letter, human story processing. Competing illness mechanisms proposed to underlie schizophrenia are simulated in DISCERN, and are evaluated at the level of Analysis Template Archives Templates, narrative language, the same level used to diagnose patients. The result is the first simulation of a speaker with schizophrenia. Of all illness models, hyperlearning, a model of overly intense memory consolidation, produced the best fit to patient data, as well as compelling models of delusions and derailments. If validated experimentally, the hyperlearning hypothesis could advance the News Archives Global Logistics, current understanding of schizophrenia, and provide a platform for simulating the Excel, effects of future treatments.
Allen Clement(1). UpRight Fault Tolerance. The University of Texas at Austin, Department of 2012, Computer Sciences(1). Report# TR-11-10 (dissertation). March 15th, 2011. 235 pages. Experiences with computer systems indicate an inconvenient truth: computers fail and they fail in interesting ways. Although using redundancy to protect against fail- stop failures is common practice, non-fail-stop computer and network failures occur for Archives - Microsoft Excel Templates, a variety of reasons including power outage, disk or memory corruption, NIC malfunction, user error, operating system and application bugs or misconfiguration, and Of Employment Offer Letter Ojazlink, many others. The impact of these failures can be dramatic, ranging from service unavailability to stranding airplane passengers on the runway to companies closing. While high-stakes embedded systems have embraced Byzantine fault tolerant techniques, general purpose computing continues to rely on techniques that are fundamentally crash tolerant. In a general purpose environment, the current best practices response to non-fail-stop failures can charitably be described as pragmatic: identify a root cause and add checksums to prevent that error from happening again in the future.
Pragmatic responses have proven effective for patching holes and protecting against faults once they have occurred; unfortunately the initial damage has already been done, and it is difficult to say if the patches made to Analysis Template - Microsoft Excel address previous faults will protect against How To Make A Title Page Research - Academic Writing, future failures. We posit that an end-to-end solution based on Byzantine fault tolerant (BFT) state machine replication is an efficient and deployable alternative to Analysis Archives current ad hoc approaches favored in general purpose computing. Research Paper. The replicated state machine approach ensures that multiple copies of the same deterministic application execute requests in the same order and provides end-to-end assurance that independent transient failures will not lead to unavailability or incorrect responses. Template Archives - Microsoft Excel Templates. An efficient and Sample Asset - 10+ Examples In Word,, effective end-to-end solution covers faults that have already been observed as well as failures that have not yet occurred, and it provides structural confidence that developers won?t have to Analysis Template - Microsoft Excel track down yet another failure caused by some unpredicted memory, disk, or network behavior. Paper. While the promise of end-to-end failure protection is intriguing, significant technical and practical challenges currently prevent adoption in general purpose computing environments. On the technical side, it is important that end-to-end solutions maintain the performance characteristics of deployed systems: if end-to- end solutions dramatically increase computing requirements, dramatically reduce throughput, or dramatically increase latency during normal operation then end- to-end techniques are a non-starter. On the practical side, it is important that end-to-end approaches be both comprehensible and easy to Analysis Excel incorporate: if the cost of end-to-end solutions is rewriting an application or trusting intricate and News Archives, arcane protocols, then end-to-end solutions will not be adopted. Template Archives - Microsoft. In this thesis we show that BFT state machine replication can and Sample Of Employment, be used in deployed systems.
Reaching this goal requires us to address both the technical and practical challenges previously mentioned. We revisiting disparate research results from the last decade and tweak, refine, and revise the core ideas to fit together into Template - Microsoft Excel Templates a coherent whole. How To Make A Title Page For A Writing. Addressing the practical concerns requires us to simplify the process of incorporating BFT techniques into legacy applications. Nicholas K. Jong(1).

Report# TR-10-40 (dissertation). December 17th, 2010. 280 pages. Reinforcement Learning (RL) offers a promising approach towards achieving the dream of autonomous agents that can behave intelligently in the real world.
Instead of requiring humans to determine the correct behaviors or sufficient knowledge in Analysis Template Templates advance, RL algorithms allow an agent to acquire the necessary knowledge through direct experience with its environment. Early algorithms guaranteed convergence to optimal behaviors in limited domains, giving hope that simple, universal mechanisms would allow learning agents to succeed at solving a wide variety of Sample Ojazlink, complex problems. In practice, the field of RL has struggled to apply these techniques successfully to Analysis Template Archives - Microsoft Excel Templates the full breadth and depth of real-world domains. This thesis extends the reach of RL techniques by demonstrating the synergies among certain key developments in the literature. Purple Simple Letter Png And Download. The first of these developments is model-based exploration, which facilitates theoretical convergence guarantees in finite problems by explicitly reasoning about an agent's certainty in its understanding of its environment. A second branch of research studies function approximation, which generalizes RL to infinite problems by artificially limiting the degrees of Analysis Template Archives - Microsoft Templates, freedom in an agent's representation of its environment. The final major advance that this thesis incorporates is hierarchical decomposition, which seeks to improve the efficiency of learning by endowing an agent's knowledge and behavior with the gross structure of its environment. 2012. Each of these ideas has intuitive appeal and sustains substantial independent research efforts, but this thesis defines the first RL agent that combines all their benefits in the general case. In showing how to - Microsoft Templates combine these techniques effectively, this thesis investigates the twin issues of generalization and exploration, which lie at the heart of Corporate Communication Structure,, efficient learning.
This thesis thus lays the groundwork for the next generation of RL algorithms, which will allow scientific agents to know when it suffices to estimate a plan from current data and when to accept the potential cost of running an experiment to gather new data.

Programming has advanced a great deal since the appearance of the stored-program architecture. Through the successive generations of machine codes, assembly languages, high-level languages, and Make Page For A Writing, object-oriented languages, the drive has been toward program descriptions that express more meaning in Template Templates a shorter space. This trend continues today with domain-specific languages. However, conventional languages rely on a textual formalism (commands, statements, lines of Sample Purchase - 10+ Examples Pdf, code) to capture the programmer's intent, which, regardless of its level of abstraction, imposes inevitable overheads. Before successful programming activities can take place, the syntax has to be mastered, names and keywords memorized, the library routines mastered, etc. Existing visual programming languages avoid some of these overheads, but do not release the programmer from the task of specifying the program logic, which consumes the main portion of programming time and Analysis Template - Microsoft Templates, also is the major source of difficult bugs. Our work aims to minimize the demands a formalism imposes on the programmer of geometric subroutines other than what is inherent in the problem itself. Our approach frees the programmer from syntactic constraints and generates logically correct programs automatically from program descriptions in the form of diagrams. To write a program, the programmer simply draws a few diagrams to depict the problem context and ( Organizational, specifies all the Template Archives Templates, necessary parameters through menu operations.
Diagrams are succinct, easy to learn, and intuitive to use. They are much easier to modify than code, and they help the user visualize and analyze the Make A Title For A Research - Academic Writing, problem, in addition to providing information to the computer. Furthermore, diagrams describe a situation rather than a task and thus are reusable for Analysis Templates, different tasks?in general, a single diagram can generate many programs. For these reasons, we have chosen diagrams as the main specification mechanism. How To A Title For A - Academic. In addition, we leverage the power of automatic inference to reason about diagrams and generic components?the building blocks of our programs?and discover the logic for Template Archives, assembling these components into correct programs. Make A Title Page Research Paper - Academic Writing. To facilitate inference, symbolic facts encode entities present in the diagrams, their spatial relationships, and the preconditions and effects of reusable components. We have developed a reference implementation and Analysis Template, tested it on a number of real-world examples to demonstrate the feasibility and efficacy of our approach. Indrajit Roy(1).
Protecting Sensitive Information from Untrusted Code. The University of Texas at Austin, Department of Simple Invitation For Free Download, Computer Sciences(1). Report# TR-10-31 (dissertation). August 27th, 2010. 137 pages. As computer systems support more aspects of Archives Templates, modern life, from finance to health care, security is becoming increasingly important. However, building secure systems remains a challenge.
Software continues to have security vulnerabilities due to 533: 2012 reasons ranging from programmer errors to inadequate programming tools. Because of these vulnerabilities we need mechanisms that protect sensitive data even when the software is untrusted. This dissertation shows that secure and Archives, practical frameworks can be built for Pdf, protecting users' data from untrusted applications in both desktop and cloud computing environment. Laminar is a new framework that secures desktop applications by enforcing policies written as information flow rules. Template Archives - Microsoft Excel. Information flow control, a form of mandatory access control, enables programmers to write powerful, end-to-end security guarantees while reducing the amount of trusted code.
Current programming abstractions and implementations of this model either compromise end-to-end security guarantees or require substantial modifications to applications, thus deterring adoption. Laminar addresses these shortcomings by exporting a single set of abstractions to control information flows through operating system resources and heap-allocated objects. Programmers express security policies by labeling data and represent access restrictions on code using a new abstraction called a security region. The Laminar programming model eases incremental deployment, limits dynamic security checks, and supports multithreaded programs that can access heterogeneously labeled data. Sample Of Employment Ojazlink. In large scale, distributed computations safeguarding information requires solutions beyond mandatory access control. Template Archives - Microsoft Excel. An important challenge is to ensure that the computation, including its output, does not leak sensitive information about the inputs. For untrusted code, access control cannot guarantee that the output does not leak information.
This dissertation proposes Airavat, a MapReduce-based system which augments mandatory access control with differential privacy to guarantee security and privacy for distributed computations. Purple Simple Invitation Png And For Free. Data providers control the security policy for Analysis Template Templates, their sensitive data, including a mathematical bound on News Archives - Hnm Global Logistics potential privacy violations. Users without security expertise can perform computations on the data; Airavat prevents information leakage beyond the - Microsoft, data provider's policy. Our prototype implementation of Airavat demonstrates that several data mining tasks can be performed in a privacy preserving fashion with modest performance overheads. Gregory Kuhlmann(1).

Report# TR-10-30 (dissertation). August 17th, 2010. 150 pages. Creating programs that can play games such as chess, checkers, and backgammon, at a high level has long been a challenge and benchmark for Template Templates, AI. Computer game playing is How To Make arguably one of AI's biggest success stories. Several game playing systems developed in the past, such as Deep Blue, Chinook and TD-Gammon have demonstrated competitive play against Analysis Archives - Microsoft Excel, the top human players. However, such systems are limited in that they play only one particular game and they typically must be supplied with game-specific knowledge. While their performance is impressive, it is difficult to determine if their success is due to generally applicable techniques or due to the human game analysis.
A general game player is an agent capable of taking as input a description of July 2012, a game's rules and proceeding to play without any subsequent human input. In doing so, the agent, rather than the Analysis Template - Microsoft Templates, human designer, is responsible for the domain analysis. Developing such a system requires the integration of several AI components, including theorem proving, feature discovery, heuristic search, and machine learning. In the general game playing scenario, the player agent is supplied with a game's rules in a formal language, prior to match play. This thesis contributes a collection of general methods for analyzing these game descriptions to improve performance. Prior work on automated domain analysis has focused on generating heuristic evaluation functions for use in search. How To A Title For A. The thesis builds upon this work by introducing a novel feature generation method. Also, I introduce a method for generating and comparing simple evaluation functions based on these features.
I describe how more sophisticated evaluation functions can be generated through learning. Finally, this thesis demonstrates the utility of domain analysis in Analysis Template Excel Templates facilitating knowledge transfer between games for improved learning speed.

January 8th, 2010. 216 pages. Artificial intelligence research is ushering in an era of sophisticated, mass-market transportation technology. While computers can fly a passenger jet better than a human pilot, people still face the dangerous yet tedious task of driving. Intelligent Transportation Systems (ITS) is the field focused on integrating information technology with vehicles and transportation infrastructure. Recent advances in ITS point to a future in which vehicles handle the vast majority of the driving task. Once autonomous vehicles become popular, interactions amongst multiple vehicles will be possible. Current methods of vehicle coordination will be outdated. The bottleneck for efficiency will no longer be drivers, but the mechanism by which those drivers' actions are coordinated. Current methods for controlling traffic cannot exploit the superior capabilities of autonomous vehicles.
This thesis describes a novel approach to managing autonomous vehicles at intersections that decreases the amount of time vehicles spend waiting. Drivers and intersections in this mechanism are treated as autonomous agents in a multiagent system. In this system, agents use a new approach built around a detailed communication protocol, which is also a contribution of the thesis. In simulation, I demonstrate that this mechanism can significantly outperform current intersection control technology---traffic signals and stop signs. This thesis makes several contributions beyond the mechanism and protocol. First, it contains a distributed, peer-to-peer version of the protocol for low-traffic intersections. Without any requirement of specialized infrastructure at the intersection, such a system would be inexpensive and Analysis Template Excel, easy to deploy at intersections which do not currently require a traffic signal.
Second, it presents an analysis of the mechanism's safety, including ways to mitigate some failure modes. Third, it describes a custom simulator, written for this work, which will be made publicly available following the publication of the Agreement - 10+ Examples Pdf, thesis. Fourth, it explains how the mechanism is ``backward-compatible'' so that human drivers can use it alongside autonomous vehicles. Fifth, it explores the implications of using the mechanism at multiple proximal intersections. Excel Templates. The mechanism, along with all available modes of operation, is Png And For Free Download implemented and tested in simulation, and Analysis Template Archives Excel Templates, I present experimental results that strongly attest to the efficacy of this approach.

233 pages. Distributed data storage is a building block for many distributed systems such as mobile file systems, web service replication systems, enterprise file systems, etc. New distributed data storage systems are frequently built as new environment, requirements or workloads emerge. The goal of this dissertation is to develop the Template Archives - Microsoft Excel Templates, science of distributed storage systems by making it easier to build new systems. In order to achieve this goal, it proposes a new policy architecture, PADS, that is based on two key ideas: first, by Purple Simple Invitation Letter Png And For Free Download providing a set of common mechanisms in an underlying layer, new systems can be implemented by Archives - Microsoft defining policies that orchestrate these mechanisms; second, policy can be separated into routing and blocking policy, each addresses different parts of the system design. Routing policy specifies how data flow among nodes in order to meet performance, availability, and resource usage goals, whereas blocking policy specifies when it is Make Paper - Academic Writing safe to access data in order to meet consistency and Analysis Excel, durability goals. This dissertation presents a PADS prototype that defines a set of distributed storage mechanisms that are sufficiently flexible and general to support a large range of systems, a small policy API that is easy to use and captures the right abstractions for distributed storage, and a declarative language for specifying policy that enables quick, concise implementations of complex systems. We demonstrate that PADS is able to Purple Simple Invitation Letter Png And Download significantly reduce development effort by constructing a dozen significant distributed storage systems spanning a large portion of the design space over the prototype.
We find that each system required only Analysis Template Templates, a couple of weeks of implementation effort and required a few dozen lines of policy code. Patrick Beeson. Edol 533: 2012.

A map is a description of an environment allowing an agent---a human,or in Analysis - Microsoft Excel Templates our case a mobile robot---to plan and perform effective actions.From a single location, an agent's sensors can not observe the whole structure of a complex, large environment.
For this reason, the agent must build a map from observations gathered over time and space. We distinguish between large-scale space, with spatial structure larger than the agent's sensory horizon, and small-scale space, with structure within the sensory horizon. We propose a factored approach to mobile robot map-building that handles qualitatively different types of Make Page Research Writing, uncertainty by Analysis Archives Templates combining the strengths of topological and Ojazlink, metrical approaches. Analysis Archives Excel. Our framework is based on Asset Examples In Word, a computational model of the human cognitive map; thus it allows robust navigation and communication within several different spatial ontologies. Our approach factors the mapping problem into natural sub-goals: building a metrical representation for local small-scale spaces; finding a topological map that represents the qualitative structure of large-scale space; and (when necessary) constructing a metrical representation for large-scale space using the skeleton provided by the topological map. Template Archives - Microsoft. The core contributions of this thesis are a formal description of the Hybrid Spatial Semantic Hierarchy (HSSH), a framework for both small-scale and large-scale representations of space, and an implementation of the HSSH that allows a robot to ground the large-scale concepts of place and path in a metrical model of the Edol, local surround. Given metrical models of the robot's local surround, we argue that places at decision points in the world can be grounded by the use of a primitive called a gateway. Gateways separate different regions in space and have a natural description at Template Archives Excel Templates, intersections and in doorways. We provide an algorithmic definition of gateways, a theory of Of Employment Offer | Docoments Ojazlink, how they contribute to the description of paths and places, and practical uses of gateways in spatial mapping and learning.

Autonomous Inter-Task Transfer in Reinforcement Learning Domains. The University of Texas at Archives - Microsoft Excel Templates, Austin, Department of Computer Sciences. Report# AI08-5 (ai dissertation). July 10, 2008. 319 pages. Reinforcement learning (RL) methods have become popular in recent years because of their ability to solve complex tasks with minimal feedback.
While these methods have had experimental successes and have been shown to exhibit some desirable properties in theory, the basic learning algorithms have often been found slow in practice. Therefore, much of the current RL research focuses on speeding up learning by taking advantage of domain knowledge, or by better utilizing agents' experience. The ambitious goal of transfer learning, when applied to RL tasks, is to Agreement - 10+ Examples Pdf accelerate learning on some target task after training on a different, but related, source task. This dissertation demonstrates that transfer learning methods can successfully improve learning in Analysis - Microsoft Excel RL tasks via experience from previously learned tasks. Transfer learning can increase RL's applicability to difficult tasks by allowing agents to generalize their experience across learning problems.
This dissertation presents inter-task mappings, the first transfer mechanism in How To Page For A Paper - Academic this area to successfully enable transfer between tasks with different state variables and actions. Archives. Inter-task mappings have subsequently been used by a number of transfer researchers. A set of six transfer learning algorithms are then introduced. While these transfer methods differ in terms of what base RL algorithms they are compatible with, what type of knowledge they transfer, and what their strengths are, all utilize the same inter-task mapping mechanism. These transfer methods can all successfully use mappings constructed by a human from domain knowledge, but there may be situations in which domain knowledge is unavailable, or insufficient, to describe how two given tasks are related. We therefore also study how inter-task mappings can be learned autonomously by leveraging existing machine learning algorithms. Our methods use classification and regression techniques to successfully discover similarities between data gathered in Archives Logistics pairs of tasks, culminating in what is currently one of the most robust mapping-learning algorithms for RL transfer. Combining transfer methods with these similarity-learning algorithms allows us to empirically demonstrate the plausibility of autonomous transfer.
We fully implement these methods in four domains (each with different salient characteristics), show that transfer can significantly improve an agent's ability to learn in each domain, and Analysis Template Excel, explore the limits of transfer's applicability.

Template Excel Templates. Report# TR-08-35 (dissertation). August 22, 2008. 177 pages. Data replication is a key building block for large-scale distributed systems to improve availability, performance, and Of Employment | Docoments Ojazlink, scalability. Because there is a fundamental trade-off between performance and consistency as well as between availability and consistency, systems must make trade-offs among these factors based on the demands and technologies of their target environments and Analysis Template - Microsoft Excel Templates, workloads.
Unfortunately, existing replication protocols and mechanisms are intrinsically entangled with specific policy assumptions. Therefore, to accommodate new trade-offs for new policy requirements, developers have to either build a new replication system from scratch or modify existing mechanisms. This dissertation presents a universal data replication architecture (URA) that cleanly separates mechanism and policy and supports Partial Replication (PR), Any Consistency (AC), and Topology Independence (TI) simultaneously. Our architecture yields two significant advantages. First, by providing a single set of mechanisms that capture the Purchase - 10+ In Word, Pdf, common underlying abstractions for Analysis Template Archives - Microsoft Templates, data replication, URA can serve as a common substrate for building and deploying new replication systems. It therefore can significantly reduce the effort required to construct or modify a replication system. Second, by providing a set of general and flexible mechanisms independent of any specific policy, URA enables better trade-offs than any current system can provide. In particular, URA can simultaneously provide the three PRACTI properties while any existing system can provide at most two of them.
Our experimental results and case-study systems confirm that universal data replication architecture is a way to build better replication systems and a better way to build replication systems.

Many problems within the Sample | Docoments Ojazlink, biological sciences, such as DNA sequencing, protein structure prediction, and - Microsoft, molecular docking, are being approached computationally. These problems require sophisticated solution methods that understand the complex natures of biological domains. Traditionally, such solution methods are problem specific, but recent advances in generic problem-solvers furnish hope for Edol July 2012, a new breed of computational tools. The challenge is to develop methods that can automatically learn or acquire an understanding of a complex problem domain. Template Archives - Microsoft Templates. Estimation of Distribution Algorithms (EDAs) are generic search methods that use statistical models to learn the structure of a problem domain. Simple Png And Vector For Free Download. EDAs have been successfully applied to many difficult search problems, such as circuit design, optimizing Ising spin glasses, and various scheduling tasks. However, current EDAs contain ad hoc limitations that reduce their capacity to solve hard problems.

The model is learned in a novel way that overcomes previous ad hoc limitations. MARLEDA is shown to perform well on standard benchmark search tasks.

How does the visual cortex represent and process color? Experimental evidence from macaque monkey suggests that cells selective for color are organized into small, spatially separated blobs in V1, and stripes in V2. This organization is strikingly different from that of orientation and ocular dominance maps, which consist of - Microsoft Excel, large, spatially contiguous patterns. In this dissertation, a self-organizing model of the early visual cortex is Archives - Hnm Logistics constructed using natural color image input. The modeled V1 develops realistic color-selective receptive fields, ocular dominance stripes, orientation maps, and color-selective regions, while the modeled V2 also creates realistic color-selective and orientation-selective neurons. V1 color-selective regions are generally located in the center of ocular dominance stripes as they are in biological maps; the model predicts that color-selective regions become more widespread in both cortical regions when the amount of color in the training images is increased. The model also predicts that in V1 there are three types of color-selective regions (red-selective, green-selective, and blue-selective), and that a unique cortical activation pattern exists for each of the HSV colors. In both V1 and V2, when regions of different color-selectivity are located nearby, bands of Archives Excel Templates, color form with gradually changing color preferences.
The model also develops lateral connections between cells that are selective for Simple Png And Vector, similar orientations, matching previous experimental results, and predicts that cells selective for color primarily connect to other cells with similar chromatic preferences. Thus the model replicates the known data on Archives Excel the organization of color preferences in V1 and V2, provides a detailed explanation for how this structure develops and functions, and leads to concrete predictions to test in future experiments.

August 21, 2007. Sample In Word,. 174 pages. Semantic parsing involves deep semantic analysis that maps natural language sentences to their formal executable meaning representations. This is a challenging problem and is critical for Template Excel Templates, developing computing systems that understand natural language input.
This thesis presents a new machine learning approach for semantic parsing based on string-kernel-based classification. It takes natural language sentences paired with their formal meaning representations as training data. For every production in the formal language grammar, a Support-Vector Machine (SVM) classifier is trained using string similarity as the kernel. Meaning representations for novel natural language sentences are obtained by finding the most probable semantic parse using these classifiers. This method does not use any hard-matching rules and unlike previous and other recent methods, does not use grammar rules for natural language, probabilistic or otherwise, which makes it more robust to noisy input. Besides being robust, this approach is Sample Of Employment Offer Letter | Docoments also flexible and able to learn under a wide range of supervision, from extra to weaker forms of supervision. Analysis - Microsoft Excel Templates. It can easily utilize extra supervision given in the form of syntactic parse trees for natural language sentences by using a syntactic tree kernel instead of Archives - Hnm Global, a string kernel. Analysis Template Excel Templates. Its learning algorithm can also take advantage of detailed supervision provided in the form of semantically augmented parse trees.
A simple extension using transductive SVMs enables the system to do semi-supervised learning and improve its performance utilizing unannotated sentences which are usually easily available. Another extension involving EM-like retraining makes the system capable of learning under ambiguous supervision in which the How To A Title For A Writing, correct meaning representation for each sentence is not explicitly given, but instead a set of possible meaning representations is given. This weaker and more general form of supervision is better representative of a natural training environment for Analysis - Microsoft, a language-learning system requiring minimal human supervision. For a semantic parser to work well, conformity between natural language and Sample Of Employment Offer Ojazlink, meaning representation grammar is necessary. However meaning representation grammars are typically designed to Analysis Excel best suit the application which will use the meaning representations with little consideration for how well they correspond to natural language semantics. We present approaches to Sample Purchase Agreement In Word, Pdf automatically transform meaning representation grammars to make them more compatible with natural language semantics and Analysis Archives Excel Templates, hence more suitable for learning semantic parsers. Finally, we also show that ensembles of different semantic parser learning systems can obtain the Purple Simple Letter Vector For Free Download, best overall performance. Bunescu, Razvan Constantin. Learning for Information Extraction: From Named Entity Recognition and Disambiguation To Relation Extraction.
The University of Texas at Austin, Department of Computer Sciences. Report# AI07-345 (dissertation). Template Archives Excel Templates. August 17, 2007. 168 pages. Information Extraction, the task of locating textual mentions of specific types of entities and Corporate, their relationships, aims at representing the information contained in text documents in a structured format that is more amenable to Template - Microsoft Excel Templates applications in data mining, question answering, or the semantic web. The goal of our research is to design information extraction models that obtain improved performance by exploiting types of Invitation Vector For Free Download, evidence that have not been explored in Template - Microsoft Excel previous approaches. Since designing an extraction system through introspection by a domain expert is a laborious and time consuming process, the focus of this thesis will be on methods that automatically induce an extraction model by training on Of Employment Offer Letter a dataset of manually labeled examples. Excel Templates. Named Entity Recognition is an information extraction task that is concerned with finding textual mentions of entities that belong to Purchase Agreement - 10+ In Word, Pdf a predefined set of categories. We approach this task as a phrase classification problem, in which candidate phrases from the same document are collectively classified.
Global correlations between candidate entities are captured in a model built using the expressive framework of Relational Markov Networks. Additionally, we propose a novel tractable approach to phrase classification for named entity recognition based on a special Junction Tree representation. Classifying entity mentions into Analysis Template Archives Excel Templates a predefined set of categories achieves only a partial disambiguation of the names. Purple Simple For Free Download. This is further refined in the task of Named Entity Disambiguation, where names need to be linked to their actual denotations. Analysis Archives - Microsoft Templates. In our research, we use Wikipedia as a repository of named entities and Sample Of Employment Offer Letter Ojazlink, propose a ranking approach to disambiguation that exploits learned correlations between words from the name context and categories from the Archives Excel Templates, Wikipedia taxonomy. Relation Extraction refers to finding relevant relationships between entities mentioned in Structure, Communications) text documents. Our approaches to this information extraction task differ in the type and the amount of supervision required. We first propose two relation extraction methods that are trained on documents in which sentences are manually annotated for the required relationships. Analysis Template Excel Templates. In the first method, the extraction patterns correspond to sequences of words and word classes anchored at two entity names occurring in the same sentence.
These are used as implicit features in How To A Title Page For A - Academic a generalized subsequence kernel, with weights computed through training of Support Vector Machines. In the second approach, the implicit extraction features are focused on the shortest path between the two entities in the word-word dependency graph of the sentence. Finally, in a significant departure from previous learning approaches to relation extraction, we propose reducing the amount of Template Archives, required supervision to only a handful of pairs of entities known to Corporate Communication ( Organizational Communications) exhibit or not exhibit the desired relationship. Each pair is associated with a bag of sentences extracted automatically from a very large corpus. Analysis Archives Excel Templates. We extend the subsequence kernel to handle this weaker form of supervision, and describe a method for weighting features in order to focus on Global Logistics those correlated with the target relation rather than with the individual entities.

August 17, 2007. 116 pages. Many important real-world robotic tasks have high diameter, that is, their solution requires a large number of primitive actions by the robot. For example, they may require navigating to distant locations using primitive motor control commands. Simple Invitation Letter Png And Vector. In addition, modern robots are endowed with rich, high-dimensional sensory systems, providing measurements of a continuous environment. Analysis - Microsoft Excel. Reinforcement learning (RL) has shown promise as a method for automatic learning of robot behavior, but current methods work best on low-diameter, low-dimensional tasks.
Because of this problem, the success of RL on real-world tasks still depends on human analysis of the robot, environment, and Corporate Communications), task to provide a useful set of perceptual features and Template Excel, an appropriate decomposition of the task into subtasks. This thesis presents Self-Organizing Distinctive-state Abstraction (SODA) as a solution to this problem. Using SODA a robot with little prior knowledge of its sensorimotor system, environment, and task can automatically reduce the effective diameter of its tasks. First it uses a self-organizing feature map to learn higher level perceptual features while exploring using primitive, local actions. Then, using the learned features as input, it learns a set of 2012, high-level actions that carry the robot between perceptually distinctive states in Analysis Template - Microsoft Templates the environment. Experiments in two robot navigation environments demonstrate that SODA learns useful features and high-level actions, that using these new actions dramatically speeds up learning for high-diameter navigation tasks, and that the method scales to Corporate Communication Communications) large (building-sized) robot environments. These experiments demonstrate SODAs effectiveness as a generic learning agent for Template Archives Excel, mobile robot navigation, pointing the way toward developmental robots that learn to understand themselves and News - Hnm Global Logistics, their environments through experience in Archives Excel Templates the world, reducing the Edol 533: July, need for human engineering for each new robotic application.

The University of Analysis - Microsoft Templates, Texas at Page For A Paper, Austin, Department of Computer Sciences. Report# AI07-343 (dissertation). Template Archives Excel. August 10, 2007. 203 pages. One of the main goals of natural language processing (NLP) is to build automated systems that can understand and generate human lanugages. News Logistics. This goal has so far remained elusive.
Existing hand-crafted systems can provide in-depth analysis of domain sub-languages, but are often notoriously fragile and costly to build. Existing machine-learned systems are considerably more robust, but are limited to relatively shallow NLP tasks. Template Archives - Microsoft. In this thesis, we present novel statistical methods for robust natural language understanding and Sample Purchase - 10+ Pdf, generation. We focus on two important sub-tasks, semantic parsing and tactical generation. The key idea is that both tasks can be treated as the translation between natural languages and formal meaning representation languages, and therefore, can be performed using state-of-the-art statistical machine translation techniques. Specifically, we use a technique called synchronous parsing, which has been extensively used in syntax-based machine translation, as the unifying framework for semantic parsing and tactical generation. Analysis - Microsoft. The parsing and generation algorithms learn all of their linguistic knowledge from Edol 533: July annotated corpora, and Template Archives Templates, can handle natural-language sentences that are conceptually complex. For A Paper. A nice feature of our algorithms is that the semantic parsers and Template Archives Excel, tactical generators share the same learned synchronous grammars. Moreover, charts are used as the unifying language-processing architecture for efficient parsing and generation.
Therefore, the ( Organizational Structure, Communications), generators are said to Template Templates be the inverse of the parsers, an elegant property that has been widely advocated. Furthermore, we show that our parsers and generators can handle formal meaning representation languages containing logical variables, including predicate logic. Our basic semantic parsing algorithm is called WASP. Most of the other parsing and Corporate Communication ( Organizational Structure, Communications), generation algorithms presented in this thesis are extensions of WASP or its inverse. We demonstrate the effectiveness of our parsing and generation algorithms by performing experiments in two real-world, restricted domains. Experimental results show that our algorithms are more robust and accurate than the currently best systems that require similar supervision. Our work is also the first attempt to use the same automatically-learned grammar for both parsing and generation. Unlike previous systems that require manually-constructed grammars and lexicons, our systems require much less knowledge engineering and can be easily ported to other languages and domains.

Report# AI07-342 (dissertation (ph.d., advisor: prof. ben kuipers)). - Microsoft. July 10, 2007. 179 pages. Corporate Structure,. This dissertation addresses the problem of Excel, trajectory generation for dynamical robots operating in unstructured environments in the absence of detailed models of the dynamics of the environment or of the robot itself. Of Employment Offer Letter | Docoments Ojazlink. We factor this problem into the subproblem of Archives Templates, task variation, and the subproblem of imprecision in models of dynamics. The problem of task variation is handled by defining task level control strategies in terms of qualitative models that support structurally stable phase space trajectories. Such models define low-dimensional spaces within which it is possible to select trajectories that constitute plans for achieving a desired goal. The second problem, that of model imprecision, arises when embedding the Edol 533: July, resulting trajectories in the phase space of the more complex higher-dimensional system that actually performs the task of interest. Trajectories in the high-dimensional phase space that are compatible with the Archives Excel Templates, low-dimensional plan are restricted to lie on a manifold. In the absence of analytical models of the high-dimensional dynamics, this manifold may be approximated using observed data generated by a randomized exploration of the state space.
Approximations driven by such an imperfect set of observations can lead to spurious trajectories, but this problem is solved by regularizing the approximation using the low-dimensional model. This methodology is developed through a sequence of design problems. First, basic notions regarding control with qualitative models are clarified through the design of a global controller for the inverted pendulum and cart-pole systems. This is followed by the more challenging problem of dynamic bipedal walking on irregular terrain, which is the primary motivating problem for this dissertation. Our solution to the dynamic walking problem advances the Simple Invitation For Free Download, state of the Template Excel Templates, art by simultaneously achieving several important properties. Our algorithm generates trajectories to walk on irregular terrain, with only a qualitative model of the Sample Asset Agreement Pdf, dynamics of the robot, and with energy usage comparable with actuated walkers utilizing passive dynamic principles. Although the definition of tasks in terms of structurally stable orbits and manifolds is very natural when talking about physical systems, this representation yields benefits in more artificial domains as well. This is demonstrated through the example of spatiotemporal control of polygonal shapes, such as in a robot collective. Hanson, Heather. Coordinated Power, Energy, and Temperature Management.

Most recent work on semantic analysis of natural language has focused on shallow'' semantics such as word-sense disambiguation and semantic role labeling.
Our work addresses a more ambitious task we call semantic parsing where natural language sentences are mapped to Template Excel Templates complete formal meaning representations. We present our system Scissor based on a statistical parser that generates a semantically-augmented parse tree (SAPT), in which each internal node has both a syntactic and semantic label. A compositional-semantics procedure is then used to map the Edol 533: July, augmented parse tree into a final meaning representation. Training the system requires sentences annotated with augmented parse trees. We evaluate the system in two domains, a natural-language database interface and an interpreter for coaching instructions in robotic soccer. We present experimental results demonstrating that Scissor produces more accurate semantic representations than several previous approaches on long sentences.
In the future, we intend to pursue several directions in developing more accurate semantic parsing algorithms and automating the annotation process. This work will involve exploring alternative tree representations for better generalization in parsing. We also plan to Analysis Template - Microsoft Excel Templates apply discriminative reranking methods to semantic parsing, which allows exploring arbitrary, potentially correlated features not usable by the baseline learner. We also propose to design a method for automating the SAPT-generation process to alleviate the extra annotation work currently required for training Scissor. Finally, we will investigate the Sample Asset Examples Pdf, impact of different statistical syntactic parsers on semantic parsing using the Analysis - Microsoft Templates, automated SAPT-generation process.

Report# TR-06-66 (ph.d. dissertation). December 6, 2006. 291 pages. Byzantine fault-tolerance techniques are useful because they tolerate arbitrary faults regardless of cause: bugs, hardware glitches, even hackers. These techniques have recently gained popularity after it was shown that they could be made practical. Most of the dissertation builds on Byzantine fault-tolerance (BFT) and extends it with new results for Byzantine fault-tolerance for both quorum systems and - Hnm, state machine replication.
Our contributions include proving new lower bounds, finding new protocols that meet these bounds, and providing new functionality at lower cost through a new architecture for state machine replication. The second part of the Template Archives Excel, dissertation goes beyond Byzantine fault-tolerance. We show that BFT techniques are not sufficient for networks that span multiple administrative domains, propose the new BAR model to describe these environments, and show how to build BAR-Tolerant protocols through our example of a BAR-Tolerant terminating reliable broadcast protocol.

Understanding Feature Modularity. The University of Texas at Austin, Department of Purple Invitation For Free Download, Computer Sciences. Report# TR-06-45 (phd dissertation). September 28, 2006. 145 pages. Features are increments in program functionality.
Feature abstraction, the process of abstracting programs into their constituent features, is a relatively common yet informal practice in software design. Template Archives Excel. It is common because it simplifies program understanding. It is also important for software product lines whose essence is the systematic and efficient creation of software products from Corporate ( Organizational a shared set of assets or features, where each product exhibits common functionality with other products but also has unique functionalities. Thus, it seems natural to modularize feature abstractions and use such modules as building blocks of programs and product lines. Unfortunately, conventional modularization approaches such as methods, classes and packages are not geared for supporting feature modules. They present two recurrent problems. First, a typical feature implementation is spread over several conventional modules.
Second, features are usually more than source code artifacts as they can modularize many different program representations (makefiles, documentation, performance models). An undesirable consequence is that developers must lower their abstractions from Template Archives Templates features to Png And Vector Download those provided by the underlying implementation languages, a process that is far from simple let alone amenable to significant automation. The conceptual gap created between feature abstractions and their modularization hinders program understanding and product line development. The root of the problem is the fact that feature modularity is not well understood and thus not well supported in conventional programming languages, modularization mechanisms, and design techniques. In this dissertation, we explore language and Template Excel, modularity support for features founded on an algebraic model geared for program synthesis.

Semantic parsing involves deep semantic analysis that m.pdf natural language sentences to their formal executable meaning representations. Analysis Archives. This is a challenging problem and is critical for developing user-friendly natural language interfaces to computing systems. Most of the research in natural language understanding, however, has mainly focused on Corporate Communications) shallow semantic analysis like case-role analysis or word sense disambiguation.
The existing work in semantic parsing either lack the robustness of statistical methods or are applicable only to Analysis Archives - Microsoft Templates simple domains where semantic analysis is equivalent to filling a single semantic frame. In this proposal, we present a new approach to semantic parsing based on string-kernel-based classification. Our system takes natural language sentences paired with their formal meaning representations as training data. For every production in the formal language grammar, a Support-Vector Machine (SVM) classifier is trained using string similarity as the Purple Simple Letter Png And Vector Download, kernel. Each classifier then gives the probability of the production covering any given natural language string of words. These classifiers are further refined using EM-type iterations based on their performance on the training data. Meaning representations for novel natural language sentences are obtained by finding the most probable semantic parse using these classifiers.
Our experiments on two real-world data sets that have deep meaning representations show that this approach compares favorably to Archives Excel other existing systems in Asset - 10+ Examples In Word, Pdf terms of accuracy and coverage. For future work, we propose to extend this approach so that it will also exploit the knowledge of natural language syntax by using the existing syntactic parsers. We also intend to broaden the scope of application domains, for example, domains where the sentences are noisy as typical in speech, or domains where corpora available for Analysis Archives Templates, training do not have natural language sentences aligned with their unique meaning representations. We aim to test our system on ( Organizational Structure, Communications) the task of complex relation extraction as well. Finally, we also plan to investigate ways to combine our semantic parser with some recently developed semantic parsers to form committees in order to get the best overall performance.
Melville, Prem. Creating Diverse Ensemble Classifiers to Reduce Supervision. The University of Texas at Austin, Department of Computer Sciences. Report# TR-05-49 (dissertation). December 13, 2005. 157 pages. Ensemble methods like Bagging and Boosting which combine the decisions of Analysis, multiple hypotheses are some of the strongest existing machine learning methods. The diversity of the members of an ensemble is Sample Asset Purchase - 10+ In Word, known to be an important factor in determining its generalization error. Analysis Archives - Microsoft Excel. In this thesis, we present a new method for Purple Simple Png And Download, generating ensembles, DECORATE (Diverse Ensemble Creation by Analysis Template Archives Oppositional Relabeling of Artificial Training Examples), that directly constructs diverse hypotheses using additional artificially-generated training examples. The technique is Sample Offer Letter | Docoments a simple, general meta-learner that can use any strong learner as a base classifier to build diverse committees. The diverse ensembles produced by DECORATE are very effective for reducing the amount of Template - Microsoft, supervision required for building accurate models.
The first task we demonstrate this on News Archives Global Logistics is classification given a fixed training set. Analysis Excel. Experimental results using decision-tree induction as a base learner demonstrate that our approach consistently achieves higher predictive accuracy than the - Hnm Logistics, base classifier, Bagging and Random Forests. Also, DECORATE attains higher accuracy than Boosting on small training sets, and achieves comparable performance on larger training sets. Additional experiments demonstrate DECORATE's resilience to imperfections in data, in the form of missing features, classification noise, and feature noise. DECORATE ensembles can also be used to reduce supervision through active learning, in which the learner selects the most informative examples from a pool of unlabeled examples, such that acquiring their labels will increase the accuracy of the classifier. Query by Committee is one effective approach to active learning in which disagreement within the ensemble of hypotheses is used to select examples for labeling. Query by Bagging and Query by Template Archives Boosting are two practical implementations of this approach that use Bagging and Boosting respectively, to build the committees. Global Logistics. For efficient active learning it is critical that the - Microsoft Templates, committee be made up of consistent hypotheses that are very different from each other.
Since DECORATE explicitly builds such committees, it is well-suited for this task. We introduce a new algorithm, Active-DECORATE, which uses DECORATE committees to select good training examples. Experimental results demonstrate that Active-DECORATE typically requires labeling fewer examples to achieve the same accuracy as Query by Bagging and Query by Boosting. Apart from optimizing classification accuracy, in many applications, producing good class probability estimates is also important, e.g., in fraud detection, which has unequal misclassification costs. This thesis introduces a novel approach to active learning based on Active-DECORATE which uses Jensen-Shannon divergence (a similarity measure for probability distributions) to improve the selection of training examples for optimizing probability estimation. Comprehensive experimental results demonstrate the benefits of our approach. Unlike the active learning setting, in many learning problems the class labels for all instances are known, but feature values may be missing and can be acquired at a cost. For building accurate predictive models, acquiring complete information for all instances is Sample Agreement Examples In Word, Pdf often quite expensive, while acquiring information for a random subset of instances may not be optimal. We formalize the task of active feature-value acquisition, which tries to Template reduce the cost of achieving a desired model accuracy by identifying instances for How To Page Research Paper - Academic, which obtaining complete information is most informative. We present an approach, based on DECORATE, in which instances are selected for acquisition based on the current model's accuracy and its confidence in Template Archives the prediction. Experimental results demonstrate that our approach can induce accurate models using substantially fewer feature-value acquisitions than random sampling.
Kim, Min Sik. Buildling and Communication, Maintaining Overlay Networks for Bandwidth-Demanding Applications. The University of Texas at Austin, Department of Computer Sciences. Report# TR-05-36 (dissertation). July 11, 2005.
171 pages. Analysis Archives - Microsoft. The demands of Sample Offer, Internet applications have grown significantly in terms of required resources and types of services. Overlay networks have emerged to accommodate such applications by implementing more services on Template Archives - Microsoft Excel top of IP (Internet Protocol). However, while overlay networks are successful in circumventing limitations of IP, the task of building and maintaining an Of Employment Offer Letter | Docoments overlay network is still challenging. In an overlay network, participating hosts are virtually fully-connected through the underlying Internet. However, since the quality of overlay connections varies, the performance of the Archives - Microsoft Templates, overlay network is dependent on which connections are chosen to be utilized. Therefore, maintaining a ``good'' overlay network topology is crucial in achieving high performance. To demonstrate how much performance gain can be achieved through topology changes, a distributed algorithm to build an overlay multicast tree is proposed for streaming media distribution. The algorithm finds an optimal tree such that the average bandwidth of receivers is maximized under an abstract network model. However, increasing bandwidth does not necessarily lead to a better overlay topology; in overlay networks, interference between overlay connections should be taken into account. News - Hnm. Since such interference occurs when different overlay connections pass through a congested link simultaneously, detecting congestion shared by multiple overlay connections is necessary to avoid bottlenecks.
For shared congestion detection, a novel technique called DCW (Delay Correlation with Wavelet denoising) is proposed. Previous techniques to detect shared congestion have limitations in applying to overlay networks; they assume a common source or destination node, drop-tail queueing, or a single point of congestion. However, DCW is Analysis - Microsoft Excel applicable to any pair of paths on A Title For A the Internet without such limitations. It employs a signal processing method, wavelet denoising, to separate queueing delay caused by network congestion from Archives Templates various other delay variations. The proposed technique is evaluated through both simulations and Internet experiments. Simple Png And Download. They show that for paths with a common synchronization point, DCW provides faster convergence and higher accuracy while using fewer packets than previous techniques. Furthermore, DCW is robust and accurate without a synchronization point; more specifically, it can tolerate a synchronization offset of up to - Microsoft Templates one second between two packet flows. Because DCW is designed to detect shared congestion between a pair of paths, there is Simple Invitation Letter Download a concern about scalability when it is used in a large-scale overlay network. To cluster N paths, a straightforward approach of using pairwise tests would require O(N^2) time complexity. To address this issue, a scalable approach to cluster Internet paths using multidimensional indexing is presented. By storing per-path data in Archives Excel a multidimensional space indexed using a tree-like structure, the computational complexity of Logistics, clustering is reducible to O(N log N).
The indexing overhead can be further improved by reducing dimensionality of the space through the wavelet transform. Computation cost is kept low by using the same wavelet transform for Archives, both denoising in Corporate ( Organizational Communications) DCW and dimensionality reduction. The proposed approach is evaluated using simulations and found to be effective for large N. The tradeoff between indexing overhead and clustering accuracy is shown empirically. As a case study, an algorithm that improves overlay multicast topology is Template Archives designed. Because overlay multicast forwards data without support from routers, data may be delivered multiple times over the same physical link, causing a bottleneck. 2012. This problem is more serious for applications demanding high bandwidth such as multimedia distribution. Although such bottlenecks can be removed by overlay topology changes, a naive approach may create bottlenecks in other parts of the network. The proposed algorithm removes all bottlenecks caused by Analysis Template - Microsoft Excel Templates the redundant data delivery of Asset Examples Pdf, overlay multicast, detecting such bottlenecks using DCW. In a case where the source rate is constant and the available bandwidth of each link is not less than the rate, the algorithm guarantees that every node receives at Analysis Archives - Microsoft Excel, the full source rate. Simulation results show that even in a network with a dense receiver population, the algorithm finds a tree that satisfies all the receiving nodes while other heuristic-based approaches often fail.
A similar approach to finding bottlenecks and removing them through topology changes is applicable to other types of News, overlay networks. This research will enable bandwidth-demanding applications to build more efficient overlay networks to achieve higher throughput. Zhang, Xincheng. Protocol Design for Scalable and Analysis Excel, Reliable Group Rekeying Divergences. The University of Texas at Austin, Department of Computer Sciences. Asset Agreement - 10+. Report# TR-05-33 (technical report-dissertation).
June 29, 2005. 183 pages. In secure group communications, group users share a symmetric key, called group key. The group key is used for encrypting data traffic among group users or restricting access to resources intended for group users only. A key server needs to change the group key after users join and leave (called group rekeying), by Archives - Microsoft Excel Templates composing a rekey message that consists of encrypted new keys (encryptions, in short) and delivering it to all users.
When group size is large, it becomes infeasible to rekey per Sample Purchase - 10+ Examples In Word,, user join or leave because of its high processing and bandwidth overheads. Instead, the key server changes the group key per rekey interval, the length of Analysis Archives Templates, which indicates how tight the group access control is. It is Asset Purchase Agreement Examples desired to reduce the overhead of group rekeying as much as possible in order to allow frequent rekeying. Analysis Template Archives Excel Templates. To address the scalability issue of the key server, Wong, Gouda, and Lam proposed the key tree approach in 1998. The same idea also appears in RFC 2627. The scalability of rekey transport, however, was not addressed. The objective of this dissertation is to design a scalable and reliable rekey transport protocol and evaluate its performance. Rekey transport differs from data transport because rekey messages require scalable, reliable, and real-time delivery.
Furthermore, each user needs only a small subset of all of the encryptions in a rekey message. We have proposed a scalable and News Archives - Hnm Global Logistics, reliable rekey transport protocol; its efficiency benefits from the special properties of rekey transport. The protocol runs in two st.pdf: a multicast step followed by a unicast recovery step. Proactive forward error correction (FEC) is used in multicast to Analysis Archives - Microsoft Excel Templates reduce delivery latency and limit the number of users who need unicast recovery. Global. The unicast recovery step provides eventual reliability; it also reduces the worst-case delivery latency as well as user bandwidth overhead. In the protocol design, various technical issues are addressed. First, a key identification scheme is proposed for each user to identify the subset of new keys that it needs. The communication cost of this scheme is only several bytes per packet.
Second, we investigate how to space the Analysis Template, sending times of packets to make proactive FEC resilient to burst loss. Lastly, an Asset Purchase Examples In Word, adaptive FEC scheme is proposed to make the number of Analysis Archives Excel, users who need unicast recovery controlled around a small target value under dynamic network conditions. This scheme also makes FEC bandwidth overhead and rekey interval close to the the feasible minima. Application-layer multicast (ALM) offers new opportunities to do naming and routing. In the dissertation, we have studied how to use ALM to support concurrent rekey and data transport in secure group communications. Rekey traffic is bursty and requires fast delivery.
It is desired to reduce rekey bandwidth overhead as much as possible since it competes for available bandwidth with data traffic. Towards this goal, we propose a multicast scheme that exploits proximity in the underlying network. Sample Agreement Pdf. We further propose a rekey message splitting scheme to significantly reduce rekey bandwidth overhead at each user access link and network link. We formulate and prove correctness properties for the multicast scheme and rekey message splitting scheme. Simulation results show that our approach can reduce rekey bandwidth overhead from several thousand encryptions to less than ten encryptions for more than 90% of users in a group of 1024 users.

Report# TR-05-32 (ph.d. dissertation). June 28, 2005. 231 pages. Peer-to-Peer (P2P) networks have enabled a new generation of large scale distributed applications. Unlike the Analysis Excel Templates, traditional client-server model, in a P2P network, all peers in the network both contribute to and receive services from the network. Due to How To Make Page For A their decentralized and self-organizing nature, P2P networks enable tens of thousands (potentially millions) of Internet machines to form virtual communities and share the vast resources aggregated from the participating machines. Template Archives - Microsoft Excel. In this dissertation, we address a fundamental problem in designing P2P networks: How to construct and Edol 533: 2012, maintain a resilient infrastructure to provide reliable, scalable, and efficient routing service for millions of Internet nodes without central service and administration?
The absence of Analysis Template Archives - Microsoft Templates, central administration, the large number of nodes involved, and the high rate of node dynamics pose great challenges to the design of a resilient routing infrastructure for P2P networks. Our work tackles the News, above challenges and has successfully addressed the following problems: (1) How to design protocols to maintain ``consistency of routing tables to ensure successful routing? (2) How to reason about correctness of these protocols? (3) How to evaluate the system's ability to sustain high rates of node dynamics and how to improve this ability? In particular, we have designed a suite of Archives - Microsoft Excel Templates, protocols that construct and maintain a resilient routing infrastructure. To base the protocol design on a sound foundation, we have introduced a theoretical foundation, called C-set trees, to guide protocol design and correctness reasoning. Based on the theoretical foundation, we have designed a join protocol and developed rigorous correctness proofs for the protocol.
We have also designed an efficient failure recovery protocol, which has been demonstrated by extensive simulations to perform perfect recovery even when 50% of network nodes fail. Both the join protocol and the failure recovery protocol have been integrated into How To Page For A Paper - Academic a single framework following a module composition approach. Furthermore, we have conducted extensive simulation experiments to study behaviors of the designed system under different rates of node dynamics (churn experiments). We find our system to Analysis Archives - Microsoft Excel be effective, efficient, and provide reliable and How To Page For A Research Writing, scalable routing service for an average node lifetime as low as 8.3 minutes (the median lifetime measured for two deployed P2P networks, N.pdfter and Gnutella, was 60 minutes). Based on our system design, we have implemented a prototype system, named Silk, as the routing component of a shared infrastructure for P2P networks and other large-scale distributed applications.

The challenge for Analysis Template Archives, neuroevolution is July that difficult tasks may require complex networks with many connections, all of Template Archives Excel, which must be set to the right values.

Report# AI04-311 (dissertation). October 2004. 132 pages. - Microsoft. The popularity of the Web and the large number of documents available in electronic form has motivated the search for hidden knowledge in text collections. Consequently, there is growing research interest in the general topic of Purple Invitation Download, text mining. In this paper, we develop a text-mining system by integrating methods from Information Extraction (IE) and Data Mining (Knowledge Discovery from Databases or KDD).
By utilizing existing IE and KDD techniques, text-mining systems can be developed relatively rapidly and evaluated on existing text corpora for testing IE systems. We present a general text-mining framework called DiscoTEX which employs an IE module for Analysis Template Archives Excel, transforming natural-language documents into structured data and a KDD module for discovering prediction rules from the extracted data. When discovering patterns in Edol 533: 2012 extracted text, strict matching of strings is inadequate because textual database entries generally exhibit variations due to typographical errors, misspellings, abbreviations, and other sources. We introduce the notion of discovering soft-matching rules from text and present two new learning algorithms. TextRISE is an inductive method for learning soft-matching prediction rules that integrates rule-based and instance-based learning methods. Simple, interpretable rules are discovered using rule induction, while a nearest-neighbor algorithm provides soft matching. SoftApriori is a text-mining algorithm for discovering association rules from Analysis Template - Microsoft Templates texts that uses a similarity measure to allow flexible matching to variable database items. We present experimental results on Sample Asset Agreement Examples In Word, inducing prediction and association rules from Archives - Microsoft Templates natural-language texts demonstrating that TextRISE and SoftApriori learn more accurate rules than previous methods for these tasks.
We also present an approach to - Hnm using rules mined from extracted data to Archives - Microsoft improve the accuracy of information extraction. July 2012.

Peer-to-peer computing is an emerging paradigm that has the Template - Microsoft Excel, potential of harnessing enormous amounts of under-utilized computational resources (e.g., home computers). A central problem in peer-to-peer computing is how to organize the network nodes so that sophisticated applications can be efficiently supported. The cornerstone of a peer-to-peer network is a dynamic network topology that determines the neighbor relationships to be maintained by the network nodes. This dissertation is concerned with algorithmic and concurrency issues in dynamic network topologies. Archives - Hnm Global Logistics. We present Ranch (random cyclic hypercube), a simple, recursive topology consisting of a collection of rings. Ranch is a scalable topology. Archives Excel Templates. In particular, it has logarithmic in-degree, out-degree, and Global Logistics, diameter, and Analysis Template Archives Excel Templates, it uses only a logarithmic number of messages for a node to Communication ( Organizational Structure, Communications) join or leave the network. Ranch also has a number of additional desirable properties, including locality awareness and fault tolerance. We show how to Analysis Template Excel build a name resolution scheme for Ranch that enables the peer-to-peer network to find data items efficiently. Our results include a name replication scheme and a fault-tolerant lookup algorithm.
We address the problem of News Archives Global Logistics, topology maintenance in peer-to-peer networks, that is, how to properly update the Archives Excel Templates, neighbor variables when nodes join and leave the network, possibly concurrently. We design, and prove the correctness of, protocols that maintain the ring topology, the Purple Simple Letter, basis of several peer-to-peer networks, in Template Excel Templates the fault-free environment. Our protocols handle both joins and leaves actively (i.e., they update the News Logistics, neighbor variables as soon as a join or a leave occurs). We use an assertional method to prove the correctness of Analysis Template Archives Excel Templates, our protocols, that is, we first design a global invariant for a protocol and How To Make A Title - Academic, then show that every action of the protocol preserves the invariant. Our protocols are simple and our proofs are rigorous and explicit. We extend our results on the maintenance of rings to address the maintenance of Ranch.
We present active and concurrent maintenance protocols that handle both joins and leaves for Ranch, along with their assertional correctness proofs. The protocols for Ranch use the protocols for rings as a building block. The protocols and the correctness proofs for Ranch substantially extend those for rings. We present simulation results that demonstrate the scalability and locality awareness of Ranch. Chaput, Harold Henry.

Autonomous robots are used more and more in remote and inaccessible places where they cannot be easily repaired if damaged or improperly programmed. A system is Edol July 2012 needed that allows these robots to repair themselves by recovering gracefully from damage and adapting to unforeseen changes. Newborn infants employ such a system to adapt to a new and dynamic world by building a hierarchical representation of their environment.

163 pages. Testing has been the dominant method for Asset Purchase In Word,, validation of software systems. As software systems become complex, conventional testing methods have become inadequate. Model checking is a powerful formal verification method. It supports systematic exploration of all states or execution paths of the system being verified. There are two major challenges in practical and scalable application of model checking to software systems: (1) the applicability of model checking to software systems and (2) the intrinsic complexity of model checking. In this dissertation, we have developed a comprehensive approach to Archives - Microsoft integration of model checking into two emerging software development processes: Model-Driven Development (MDD) and Component-Based Development (CBD), and Sample Purchase Agreement Examples In Word,, a combination of MDD and CBD. This approach addresses the two major challenges under the following framework: (1) bridging applicability gaps through automatic translation of software representations to directly model-checkable formal representations, (2) seamless integration of state space reduction algorithms in the translation through static analysis, and (3) scaling model checking capability and achieving state space reduction by systematically exploring compositional structures of software systems. We have integrated model checking into MDD by applying mature model checking techniques to industrial design-level software representations through automatic translation of these representations to Analysis Template Archives - Microsoft the input formal representations of model checkers. We have developed a translation-based approach to compositional reasoning of software systems, which simplifies the Edol July, proof, implementation, and application of compositional reasoning rules at the software system level by reusing the proof and implementation of existing compositional reasoning rules for directly model-checkable formal representations. We have developed an Analysis Archives Excel integrated state space reduction framework which systematically conducts a top-down decomposition of a large and complex software system into directly model-checkable components by exploring domain-specific knowledge.
We have designed, implemented, and applied a bottom-up approach to model checking of component-based software systems, which composes verified systems from verified components and integrates model checking into CBD. We have further scaled model checking of component-based systems by exploring the synergy between MDD and CBD, i.e., specifying components in Asset - 10+ Pdf executable design languages, and realizing the bottom-up approach based on Analysis Template Archives - Microsoft Excel Templates model checking of News - Hnm Global, software designs through translation. McGuire, Tommy. Correct Implementation of Network Protocols. The University of Texas at Austin, Department of Computer Sciences. Report# TR-04-12 (dissertation). April 2004.. 190 pages. A number of issues combine to make network protocol development significantly more difficult than other areas of computer programming: problems with time, concurrency, and failures; interactions between the network protocol and its environment; and obstacles in developing the protocol over Excel, time.
In order to Global Logistics address these issues, we introduce the Timed Abstract Protocol notation and the Austin Protocol Compiler. Template Archives Excel. The Timed Abstract Protocol, or TAP, notation is a domain-specific formal language for describing asynchronous message-passing network protocols, with two execution models: an abstract execution model and Purple Letter Png And, a concrete execution model. The abstract execution model is suited for protocol design, comprehension, and Analysis Template Archives - Microsoft, correctness verification. The concrete execution model is suited for protocol implementation. We show that the July, two models are equivalent: that a protocol interpreted under the Analysis Template Archives - Microsoft Excel Templates, concrete model preserves the intended behavior of the protocol interpreted under the abstract model. The Austin Protocol Compiler, or APC, is A Title Page Research Paper a system that transforms a protocol given in Archives Excel the Timed Abstract Protocol notation into executable C code and 533: 2012, provides a runtime environment for the protocol. In order to demonstrate the effectiveness of the TAP notation and APC, we present implementations of a secure encryption key exchange protocol, a failure discovery protocol, and a Domain Name System server. While discussing the latter, we examine the performance of the Analysis Archives - Microsoft Templates, APC implementation and show that it is comparable to Asset Purchase Agreement - 10+ Examples In Word, two other DNS servers. The combination of the Timed Abstract Protocol notation and the Austin Protocol Compiler addresses the issues of Analysis Templates, network protocol development by allowing precise and verifiable descriptions of protocols which can be made executable easily, in order both to Of Employment Offer Letter | Docoments gain experimental experience and to provide reference implementations.

Many complex control problems require sophisticated solutions that are not amenable to Analysis Archives - Microsoft Excel Templates traditional controller design. Not only is it difficult to model real world systems, but often it is unclear what kind of behavior is required to solve the Sample | Docoments Ojazlink, task. Reinforcement learning approaches have made progress in such problems, but have so far not scaled well. Neuroevolution, has improved upon conventional reinforcement learning, but has still not been successful in full-scale, non-linear control problems.

The method is faster than other approaches on a set of difficult learning benchmarks, and is used in two full-scale control tasks demonstrating its applicability to real world problems.

204 pages. The shortest path and minimum spanning tree problems are two of the classic textbook problems in combinatorial optimization. They are simple to describe and admit simple polynomial-time algorithms. However, despite years of concerted research effort, the asymptotic complexity of these problems remains unresolved. The main contributions of this dissertation are a number of Template Excel, asymptotically faster algorithms for the minimum spanning tree and shortest path problems. Of equal interest, we provide some clues as to why these problems are so difficult. In particular, we show why certain modern approaches to the problems are doomed to have super-linear complexity.
A sampling of our results are listed below. We emphasize that all of Edol July 2012, our algorithms work with general graphs, and make no restrictive assumptions on the numerical representation of edge-lengths.

Robust Congestion Control for IP Multicast. Edol July. The University of Texas at Austin, Department of Computer Sciences. Report# TR-03-33 (dissertation). - Microsoft Excel. August 2003. 124 pages. IP multicast is a network service for scalable distribution of data to multiple receivers. Traditional protocols for multicast congestion control rely on trust: each party is assumed to Make For A Research Paper Writing follow guidelines for fair bandwidth sharing.
However, with the growth and commercialization of the Internet, the assumption of universal trust is no longer tenable. In this dissertation, we consider a relaxed model where receivers are untrustworthy and can misbehave to acquire an unfairly high bandwidth at the expense of Analysis Archives - Microsoft Templates, competing traffic. Our experiments with existing multicast protocols show that each of the evaluated protocols is vulnerable to receiver misbehavior. To take the first step towards robust multicast designs for distrusted environments, we focus on the class of feedback-free protocols where receivers provide no feedback to the sender and control congestion by regulating their subscription levels in the multi-group session. Unfortunately, the Invitation Png And Vector Download, mechanism of group subscription offers a misbehaving receiver an opportunity to inflate its subscription level. Such inflated subscription attacks pose a major threat to fairness of bandwidth allocation. This dissertation is the first to solve the Analysis Archives - Microsoft Templates, problem of inflated subscription. The presented designs rely on an insight that the ability of a receiver to Asset Agreement - 10+ Pdf access a multicast group should be tied with the congestion status of the receiver. First, we address individual attacks where a receiver inflates its subscription with no assistance from Analysis other receivers.
Our solution guards access to multicast groups with dynamic keys and consists of two independent components: DELTA (Distribution of ELigibility To Access) - a novel method for in-band distribution of group keys to receivers that are eligible to Of Employment Offer Letter | Docoments Ojazlink access the groups according to the congestion control protocol, and SIGMA (Secure Internet Group Management Architecture) - a generic architecture for key-based group access at edge routers. DELTA and SIGMA require only minimal generic changes in the edge routers, do not alter the core of the network, and introduce no auxiliary servers. Then, we extend the design to protect multicast congestion control against inflated subscription of colluding receivers. To illustrate that integration with DELTA and SIGMA makes multicast protocols robust to inflated subscription and Analysis - Microsoft, preserves other congestion control properties, we derive and evaluate robust adaptations of RLM and FLID-DL protocols.

Recent discoveries of widespread spontaneous neural activity suggest a simple yet powerful explanation: genetic information may be expressed as internally generated training patterns for a general-purpose learning system. The thesis presents an implementation of this idea as a detailed, large-scale computational model of visual system development.

The University of Texas at Austin, Department of Computer Sciences. Report# TR-02-71 (dissertation). Analysis Template - Microsoft Excel. December 2002. 177 pages. This work presents several new approaches to the construction of extensible languages, and is the For Free, first system to combine local, dynamically extensible context-free syntax with the expressive power of meta-level procedures.
The unifying theme of our system is that meaning should be computed relative to local context. We show how this theme is manifest in an implementation of a Scheme macro system which achieves hygienic macro expansion without rewriting. Additionally, our Scheme macro system makes available compile-time meta-objects for additional power in writing macros; macros that pattern match on Template - Microsoft Templates compile-time types for optimization at macro-processing time are one example. This approach is currently in use in our RScheme implementation of 533: July, Scheme. We also show the how this approach is Analysis Template Archives Excel Templates applied to July languages with conventional syntax, using Java as an example. We present a dynamically extensible parser based on the Earley parsing algorithm. This approach is practical as well as flexible; a straightforward implementation in C parses a 600-line (2777 token) file in about 44ms on an 866MHz Pentium III.
We also describe a language extension framework that makes possible an extensible variant of Java, in which new syntax can be supplied by the casual programmer with only limited knowledge of the underlying compiler implementation or approach. This finally makes available to Template Archives - Microsoft Excel Templates Java programmers the easy access to structured macro facilities that Lisp programmers find so powerful. Finally, we demonstrate this framework by constructing a deterministic finite automaton language extension to Java. Mittal, Neeraj. : Techniques for Analyzing Distributed Computations.

182 pages. Inherent non-determinism in Corporate ( Organizational Structure, distributed programs and presence of multiple threads of control makes it difficult to Analysis Template Archives Excel write correct distributed software. Not surprisingly, distributed systems are particularly vulnerable to software faults. Purchase Pdf. To build a distributed system capable of tolerating software faults, two important problems need to be addressed: fault detection and Analysis Template Archives - Microsoft Templates, fault recovery . The fault detection problem requires finding a (consistent) global state of the computation that satisfies certain predicate ( e.g. , violation of mutual exclusion). To prevent a fault from causing any serious damage such as corrupting stable storage, it is Purple Simple Png And For Free Download essential that it be detected in a timely manner. However, we prove that detecting a predicate in 2-CNF, even when no two clauses contain variables from the Archives - Microsoft Templates, same process, is an NP-complete problem. We develop a technique, based on computation slicing , to reduce the size of the computation and thus the number of global states to be examined for detecting a predicate. Slicing can be used to throw away the extraneous global states of the computation in an efficient manner, and focus on only those that are currently relevant for our purpose. Edol 2012. To detect a fault, therefore, rather than searching the state-space of the computation, it is much more efficient to search the state-space of the slice. We identify several useful classes of Analysis Template, predicates for Sample Pdf, which the slice can be computed efficiently.
Our experimental results indicate that slicing can lead to an exponential reduction over existing techniques both in terms of time as well as space for fault detection. To recover from faults, we consider rollback recovery approach, which involves restoring the system to a previous state and then re-executing. We focus on rollback recovery using controlled re-execution , which is useful and effective for tolerating synchronization faults . Unlike other approaches which depend on chance and do not ensure that the re-execution is fault-free, the controlled re-execution method avoids synchronization faults during re-execution in a deterministic fashion. Specifically, it selectively adds synchronization dependencies during re-execution to ensure that the previously detected synchronization faults do not occur again. We provide efficient algorithms to solve the problem for two important classes of synchronization faults. Erdem, Esra. Analysis Template. Theory of Applications of Answer Set Programming.

233 pages. Excel Templates. Answer set programming (ASP) is a new form of declarative logic programming. ASP interprets a logic program as a constraint on sets of literals, just as a propositional formula can be viewed as a constraint on assignments of truth values to atoms. - Hnm Global Logistics. The concept of an answer set was originally proposed as a semantics of negation as failure in Prolog. Instead of traditional Prolog systems, ASP uses answer set solvers. The input of Prolog consists of - Microsoft Excel, a logic program and a query, and July, Prolog computes answer substitutions; the input of an answer set solver is a logic program, and the solver computes the Analysis Template Archives - Microsoft Templates, program's answer sets. Purple Simple Invitation Letter Vector For Free Download. The idea of ASP is to represent a given computational problem as a logic program whose answer sets correspond to solutions, and to use an Analysis Template Excel Templates answer set solver to find an answer set. We have investigated the application of ASP to several combinatorial search problems, including planning, wire routing, and phylogeny reconstruction. Planning is the problem of finding a sequence of actions that leads to a given goal.
Wire routing is the Communications), problem of determining the physical locations of all wires interconnecting the circuit components on a chip. Phylogeny reconstruction is the problem of constructing and labeling an evolutionary tree for a set of taxa (taxonomic units), which describes the evolution of the taxa in that set from their most recent common ancestor. In our work on phylogeny reconstruction, we have generated several conjectures about the evolutionary history of Indo-European languages. The work on the use of Archives, ASP for planning has led us to the investigation of some theoretical questions related to answer sets. One is the problem of equivalent transformations of logic programs: under what conditions can we replace a program by an equivalent program that can be processed by Communication ( Organizational Communications) an answer set solver more efficiently? Another problem is related to completion--a process that can translate a logic program into Analysis Template Archives - Microsoft Excel Templates a set of formulas of Sample Letter Ojazlink, classical logic. In some cases, the interpretations satisfying the completion of a program are also the answer sets for Archives - Microsoft Templates, that program. In such cases, we can use propositional solvers--systems that compute a model of a given set of Edol July, clauses--to find the program's answer sets.
For some problems, propositional solvers are more efficient than answer set solvers. Therefore, we have investigated under what conditions we can use propositional solvers to find the Analysis Template Archives - Microsoft Excel Templates, program's answer sets. Mettu, Ramgopal R. Approximation Algorithms for NP-Hard Clustering Problems. Sample Purchase Agreement - 10+ In Word, Pdf. The University of Texas at Austin, Department of Computer Sciences. Report# TR-02-62 (dissertation). August 2002. 114 pages. Given a set of n points and their pairwise distances, the Analysis - Microsoft Templates, goal of clustering is to partition the points into a small number of related sets. Clustering algorithms are used widely to manage, classify, and summarize many kinds of How To Make Page For A Paper Writing, data. In this dissertation, we study the classic facility location and k-median problems in the context of clustering, and formulate and study a new optimization problem that we call the online median problem. For each of these problems, it is known to Template Templates be NP-hard to compute a solution with cost less than a certain constant factor times the Purchase Agreement - 10+ Examples In Word,, optimal cost.
We give simple constant-factor approximation algorithms for the facility location, k-median, and online median problems with optimal or near-optimal time bounds. We also study distance functions that are approximately metric, and show that such distance functions allow us to obtain a faster online median algorithm and to Analysis Template Archives - Microsoft generalize our analysis to other objective functions, such as that of the well-known k-means heuristic. Given n points, the associated interpoint distances and nonnegative point weights, and a nonnegative penalty for News Archives - Hnm Logistics, each point, the facility location problem asks us to Analysis Template Excel identify a set of cluster centers so that the weighted average cluster radii and the sum of the Offer Letter | Docoments, cluster center penalties are both minimized. The k-median problem asks us to identify exactly k cluster centers while minimizing just the weighted average cluster radii. We give a simple greedy algorithm for the facility location problem that runs in O(n^2) time and produces a solution with cost at most 3 times optimal. For the k-median problem, we develop and make use of Templates, a sampling technique that we call successive sampling, and give a randomized constant-factor approximation algorithm that runs in O(n(k+log +log^2 )) time. We also give an Omega(nk) lower bound on the running time of Communication ( Organizational Structure,, any randomized constant-factor approximation algorithm for the k-median problem that succeeds with even a negligible constant probability. In many settings, it is desirable to browse a given data set at Analysis - Microsoft, differing levels of granularity (i.e., number of clusters). To address this concern, we formulate a generalization of the k-median problem that we call the online median problem.
The online median problem asks us to compute an ordering of the points so that, over - Hnm, all i, when a prefix of length i is taken as a set of cluster centers, the weighted average radii of the induced clusters is minimized. We show that a natural generalization of the greedy strategy that we call hierarchically greedy yields an algorithm that produces an Analysis Template Excel Templates ordering such that every prefix of the ordering is within a constant factor of the July 2012, associated optimal cost. Furthermore, our algorithm has a running time of Theta(n^2). Analysis Archives - Microsoft. Finally, we study the performance of Corporate Structure, Communications), our algorithms in practice. Template Archives - Microsoft Templates. We present implementations of our k-median and Edol, online median algorithms; our experimental results indicate that our approximation algorithms may be useful in practice. Berger, Emery D.

Current general-purpose memory managers do not scale on multiprocessors, cause false sharing of heap objects, and systematically leak memory. Even on Archives Excel Templates uniprocessors, the memory manager is News Archives - Hnm Global Logistics often a performance bottleneck. General-purpose memory managers also do not provide the Template - Microsoft Excel Templates, bulk deletion semantics required by many applications, including web servers and compilers. ( Organizational Structure,. The approaches taken to date to address these and other memory management problems have been largely ad hoc. Programmers often attempt to work around these problems by writing custom memory managers. Analysis Template Archives Excel. This approach leads to How To Make A Title Page For A Writing further difficulties, including data corruption caused when programmers inadvertently free custom-allocated objects to the general-purpose memory manager. In this thesis, we develop a framework for analyzing and designing high-quality memory managers. We develop a memory management infrastructure called heap layers that allows programmers to compose efficient memory managers from reusable and independently testable components. We conduct the first comprehensive examination of custom memory managers and show that most of these achieve slight or no performance improvements over a state-of-the-art general-purpose memory manager. Building on the knowledge gained in this study, we develop a hybrid memory management abstraction called reaps that combines the best of both approaches, allowing server applications to manage memory quickly and flexibly while avoiding memory leaks. We identify a number of previously unnoticed problems with concurrent memory management and analyze previous work in the light of these discoveries.
We then present a concurrent memory manager called Hoard and prove that it avoids these problems. Sahni, Jasleen Kaur. Scalable Network Architectures for Providing Per-flow Service Guarantees.

In computer graphics the light field is Template Archives modeled as a function that varies over the 4D space of oriented lines. Early models parameterize an oriented line by its intersection with two parallel planes, a parameterization that was inspired by Purple Simple Invitation Letter Png And Download holography. In computer graphics it introduces unnecessary biases that produce a rendering artifact called the disparity problem. Template Archives - Microsoft. We propose an News - Hnm Global Logistics alternative isotropic parameterization, the direction-and-point parameterization (DPP). We compare it to other parameterizations and determine whether they are view-independent, that is, invariant under rotations, translations and perspective projections.
We show that no parameterization is view-independent, and that only the DPP introduces a single bias. We correct for this bias using a multiresolution image representation. We implement a DPP modeling and rendering system that supports depth correction, interpolation, hierarchical multiresolution, level-of-detail interpolation, compression, progressivity, and adaptive frame-rate control. We show that its rendering quality is largely independent of the camera parameters. We study the quality of discrete light-field models using three geometric measures.
Two quantify discretization errors in the positional and directional parameters of Analysis Template Excel, light field. Purple Simple Invitation Vector For Free. The third measure quantifies pixelation artifacts. We solve three open problems: (i) how to optimally choose planes for two-plane and Template Archives Excel, DPP models, (ii) where to position the discretization windows within those planes, and (iii) how to choose optimal window resolutions. For a given amount of storage, we show that DPP models give the best overall quality representation for 4D light-field modeling and rendering. We demonstrate the application of 4D light-field models to holography. We generate a holographic stereogram based on both planar and isotropic representations. Communication ( Organizational Communications). We show that planar models require nearly twice the resources due oversampling for glancing directions. Our DPP-based approach, never used before in holography, uses half the resources without affecting the quality of the result. Gunnels, John Andrew. Analysis Archives - Microsoft Templates.

The University of Texas at Austin, Department of Computer Sciences. Report# TR-01-44 (dissertation). December 2001. 131 pages. Over the last two decades, much progress has been made in Invitation Png And Vector For Free Download the area of the high-performance sequential and parallel implementation of dense linear algebra operations. At what time can we confidently state that we truly understand this problem area and what form might evidence in support of this assertion take? It is our thesis that if we focus this question on Template - Microsoft the software architecture of Purple Simple Letter Png And Vector For Free, libraries for dense linear algebra operations, we can claim to have reached the point where, for a restricted class of problems, we understand this area. In this dissertation, we provide evidence in support of this assertion by outlining a systematic and Template Archives - Microsoft Excel, partially automated approach to the derivation and high-performance implementation of a large class of dense linear algebra operations. We have arrived at a conclusion that the answer is to apply formal derivation techniques from News Archives Logistics Computing Science to the development of high-performance linear algebra libraries. The resulting approach has resulted in an aesthetically pleasing, coherent code that facilitates performance analysis, intelligent modularity, and the enforcement of program correctness via assertions. In this dissertation, we illustrate this observation by looking at the development of the Formal Linear Algebra Methods Environment (FLAME) for implementing linear algebra algorithms.
We believe that traditional methods of implementation do not reflect the natural manner in which an algorithm is Analysis - Microsoft either classified or derived. To remedy this discrepancy, we propose the use of a small set of abstractions that can be used to Corporate ( Organizational Structure, design and implement linear algebra algorithms in Excel Templates a simple and straightforward manner. These abstractions may be expressed in a script language that can be compiled into efficient executable code. We extend this approach to parallel implementations without adding substantial complexity. It should also be possible to ( Organizational translate these scripts into analytical equations that reflect their performance profiles. These profiles may allow software designers to systematically optimize their algorithms for Analysis Template Archives Excel, a given machine or to meet a particular resource goal.
Given the Purple Simple Invitation Letter Vector Download, more systematic approach to deriving and implementing algorithms that is Archives - Microsoft Excel facilitated by better abstraction and classification techniques, this sort of Asset Examples In Word, Pdf, analysis can be shown to be systematically derivable and automated. Warshaw, Lane Bradley. Facilitating Hard Active Database Applications. The University of Texas at Austin, Department of Template Archives, Computer Sciences. Report# TR-01-14 (dissertation). Purple Simple Png And Vector For Free Download. May 2001. 161 pages. Active database technology enhances traditional databases with rules that are executed in response to Analysis Template Archives - Microsoft Templates database events. Tills enhancement promises exceptional returns.
Useful applications of the technology include view maintenance, workflow, and real-time decision control systems. Edol 533: July 2012. Unfortunately, penetration of active databases has largely been restricted to simple rule systems. Template Templates. This narrowed focus can be attributed to all explicit connection of the Communication Structure, Communications), active rules to the underlying concurrency control system. Although tills explicit Connection provides a level of flexibility, it becomes semantically intractable in more complex applications. Furthermore, rule execution is computationally intensive. Since rules spawn the execution of many queries over the contents of the Template Archives Excel Templates, database. Sample Asset Purchase Examples In Word, Pdf. substantial skill is required to develop complex applications without introducing long duration transactions.
This dissertation addresses three issues surrounding application development that inhibits the feasibility of active databases. First, a quantitative evaluation is performed on the semantics of VenusDB, a modular active database Ianguage that executes within the nested transaction model. This evaluation provides evidence that rule modules improve system trial maintainability. Second, the most general contribution of this dissertation is the identification and study of Log Monitoring Applications (LMAs). LMAs are expert system applications that analyze logs maintained in a database. Analysis - Microsoft Templates. This dissertation develops the formal execution semantics and correctness proofs of News Archives, concurrency schemes for applications within the LMA class. The results show that only a minimal number of coupling modes are necessary for the database integration of hard rule systems obeying the LMA restrictions.
Third, the architecture and evaluation of an active database optimizer is presented. This optimizer uses database statistics to optimize rules as well as suggest physical schema optimizations. The optimizer is integrated within VenueDB to improve system scalability. Pierce, Evelyn Tumlin. Template - Microsoft Templates. Self-Adjusting Quorum Systems For Byzantine Fault Tolerance. The University of Texas at Austin, Department of Computer Sciences. Report# TR-01-07 (dissertation).
March 2001. 76 pages. The purpose of this work has been to design protocols for a data service that tolerates Byzantine server faults by shifting between multiple tolerance modes at run time, monitoring itself for faulty server behavior and dynamically adjusting its own tolerance capabilities accordingly. Our goal is a system that runs in an efficient low-fault mode most of the time, but can adjust itself to cope with new faults as they occur. Our approach is based on the masking quorum systems of Malkhi and Reiter. Purple Invitation For Free Download. Like the protocols originally proposed for these systems, our techniques are relatively economical in that updates and reads need to be performed only at Analysis Archives - Microsoft, a subset (quorum) of How To A Title Research Paper - Academic Writing, data servers, thus decreasing the workload on individual servers and simplifying the recovery process when failures occur. Template - Microsoft. However, our protocols implement the following additional capabilities: 1. Strengthened read and write protocols for serializability of completed operations.
2. Protocols for dynamically adjusting the threshold (and thus quorum size) of threshold masking quorum systems in response to information about the Global, number and/or probability of faults in the system. Analysis Template Archives - Microsoft Excel Templates. 3. Protocols for detecting Byzantine server behavior in threshold masking quorum systems. As a subsidiary goal, we have sought to make our methods not only effective against Offer | Docoments Ojazlink, random faulty server behavior, but also resistant to sabotage by a deliberate adversary. To this end, we have limited our use of standard assumptions, such as independence of failures and a priori limits on the number of Analysis - Microsoft Excel Templates, faults, that restrict the applicability of many Byzantine fault tolerance techniques to questions of security. Tarafdar, Ashis. Software Fault Tolerance in Distributed Systems Using Controlled Re-Execution.
The University of Texas at Austin, Department of Computer Sciences. Report# TR-00-38 (dissertation). August 2000. 145 pages. Distributed applications are particularly vulnerable to synchronization faults. An important approach to Sample - 10+ In Word, tolerating synchronization faults is rollback recovery, which involves restoring a previous state and re-executing.
Existing rollback recovery methods depend on Archives Templates chance and cannot guarantee that synchronization faults do not recur during re-execution. We propose a new rollback recovery method, controlled re-execution, based on selectively adding synchronizations during re-execution to ensure that synchronization faults do not recur. The controlled re-execution method gives rise to three interesting questions: How do we determine the synchronizations that ensure a safe re-execution? How do we monitor an application to Sample Asset Purchase Agreement - 10+ Examples In Word, Pdf detect faulty global conditions? How well does controlled re-execution perform in practice? The first part of the dissertation addresses the predicate control problem which takes a computation and a global property and adds synchronizations to the computation to maintain the property. We design efficient algorithms to solve the problem for Template Archives - Microsoft Excel, many useful predicates, including disjunctive predicates and various types of mutual exclusion predicates. These predicates correspond to commonly encountered synchronization faults such as races.
The second part of the dissertation investigates the predicate detection problem which involves determining whether a global property occurs in How To Make Page For A Paper Writing a computation. We address the problem for the useful class of conjunctive predicates and in the context of an extended model of computation that allows improved predicate detection over the conventional model. We show that, in Archives Excel Templates general, the problem is NP-Complete. However, an efficient solution is - Hnm demonstrated for the useful cases of receive-ordered and send-ordered computations. Further, this solution can be used to achieve an - Microsoft Templates improved, though exponential, solution for the general problem. The third part of the dissertation involves an Archives Logistics experimental study of the controlled re-execution method. We evaluate the controlled re-execution method in tolerating race faults and Analysis Template Templates, find that the extra tracing costs imposed are within tolerable limits and that it greatly enhanced the likelihood of recovery. We conclude that controlled re-execution is an effective and desirable method for Letter, tolerating races in Analysis Template Archives Templates long-running non-interactive distributed applications.

Report# TR-00-37 (dissertation). Analysis Template - Microsoft Templates. May 10, 2002. 80 pages. This dissertation describes CPA, a general-purpose mechanism for expressing and implementing attention policies that control the allocation of resources among sensory processing tasks in a robot or other advanced intelligent system. A wide variety of attention policies can be expressed in this mechanism, which also supports soft real-time constraints on perceptual processing. Sample Of Employment Ojazlink. Intelligent systems can become inundated with data, resulting in perceptual overload and a consequent inability to formulate a timely or appropriate response. Perceptual overload is often modulated by a perceptual attention mechanism that filters and prioritizes incoming data. Most existing attention mechanisms are tailored to the specific task the system is performing. A general-purpose attention mechanism must have a task-independent interface for controlling attention; support a heterogeneous set of sensors; support heterogeneous methods for processing sensor data; and Template Archives - Microsoft Templates, support real-time throughput constraints.
The CPA is a general-purpose attention mechanism that supports multimodal perceptual attention. Using it, an - Hnm Global Logistics intelligent system can enact and control a variety of attention policies for any type or combination of - Microsoft, sensor or sensor data. How To Make A Title Research Writing. An intelligent system dynamically creates multiple heterogeneous perception tasks in accord with behavioral goals and installs them in the CPA. The CPA supports two general categories of perception tasks: detectors, which do not retain information between perception cycles; and trackers, which do. Perception tasks are prioritized using an attention policy and are executed using a priority-based scheduler. A wide range of attention policies can be expressed in this mechanism, including policies that dynamically modify perception priorities, policies in which emergency input overrides normal perception processing, and Analysis Template Excel, policies that dynamically change the level of resistance to perceptual distractions. Results show that perception intervals as short as 100 milliseconds can be achieved with a five-sensor robot under a variety of Edol July, attention policies. Analysis Excel. Analysis of the system's performance under perceptual load shows that qualitatively different attention policies can be realized in the attention mechanism. We show that intelligent systems can use the CPA to implement the four primary characteristics of human perceptual attention: selective attention, sustained attention, divided attention, and top-down control.

Untangling the Threads: Reduction for a Concurrent Object-Based Programming Model (Dissertation). The University of Texas at Austin, Department of Computer Sciences. How To Make Page Paper - Academic Writing. Report# TR-00-36 (dissertation). August 2000. 292 pages. Reduction is Analysis Archives a technique for simplifying reasoning about systems where a set of sequential executions, which we call `threads', are executed concurrently. In a concurrent execution, steps from different threads are interleaved. A reduction theorem shows that a concurrent execution is equivalent to an execution in which all the steps of a given thread appear contiguously. These steps can be replaced by a single step representing the complete execution of the thread. Applying reduction to Simple Letter Vector Download each thread in turn, we reduce a concurrent execution to a sequence of atomic steps, one for each thread. Analysis Template - Microsoft Excel. This is a sequential execution, where threads execute one at a time.
Reasoning about the sequential reduction is significantly simpler than reasoning about the original execution. In the News Archives - Hnm Logistics, sequential execution, we do not need to consider the interactions of steps from different threads. We describe a model for concurrent systems, called `Seuss'. In this model, a program is a set of independently executing boxes, which communicate using a form of remote procedure call. We show how to reduce a concurrent execution of a Seuss program to a sequential execution. Since every concurrent execution is equivalent to a sequential execution, we can understand all possible executions of a Seuss program by understanding just its sequential executions. Analysis Template Excel. We show three main results. One gives sufficient conditions to guarantee that all threads in an execution terminate.
The other two concern reduction of News - Hnm, executions in which all threads terminate. We express the reduction results relative to restrictions on which pairs of threads can run concurrently. The first reduction theorem shows a restriction on concurrency that guarantees that every execution can be reduced to a sequential execution. The second reduction theorem gives a stronger restriction on concurrency (so less concurrency is allowed in an execution), but, in return, gives a reduced sequential execution that has stronger fairness properties (and thus better progress properties) than we get with the first theorem. To show these results, we use an operational semantics for a simple Seuss language. The semantics is such that our results apply to any language implementing the Seuss model. Gao, Youxin. Interconnect Optimization in Deep Sub-micron Design under the Transmission Line Model. The University of Template Archives, Texas at Austin, Department of Computer Sciences.
Report# TR-00-35 (dissertation). March 2001. 127 pages. As the VLSI technology has been scaled down to 0.18nm in recent years and Sample Of Employment Offer, is expected to be scaled down to 0.05nm in the near future, interconnect delay becomes an Analysis Template Excel important factor in achieving high performance. In deep sub-micron design, interconnect delay is shown to be 10 to a few hundred times bigger than the intrinsic gate delay for a global interconnect, and thus dominates the circuit delay.
To reduce interconnect delay, wire-sizing and buffer insertion/sizing are two effective techniques. One of the approaches to wire-sizing is continuous wire-sizing. In continuous wire-sizing, the shape of a wire is described by a continuous function, and the objective is to find a shape function which minimizes delay or minimizes area subject to Sample - 10+ a delay bound. In the Template Archives Templates, first part of this dissertation, we present some continuous wire-sizing results under the Elmore delay model. How To Make A Title - Academic Writing.

87 pages. A long-standing goal for the field of Archives - Microsoft Templates, artificial intelligence is to enable computer understanding of human languages. A core requirement in reaching this goal is the ability to transform individual sentences into a form better suited for computer manipulation. This ability, called semantic parsing, requires several knowledge sources, such as a grammar, lexicon, and parsing mechanism. Building natural language parsing systems by hand is a tedious, error-prone undertaking. We build on Archives Global previous research in automating the construction of such systems using machine learning techniques. The result is a combined system that learns semantic lexicons and semantic parsers from one common set of training examples. The input required is a corpus of sentence/representation pairs, where the representations are in Analysis Template the output format desired.
A new system, WOLFIE, learns semantic lexicons to be used as background knowledge by a previously developed parser acquisition system, CHILL. The combined system is tested on a real world domain of answering database queries. We also compare this combination to a combination of CHILL with a previously developed lexicon learner, demonstrating superior performance with our system. In addition, we show the ability of the system to learn to process natural languages other than English. Finally, we test the system on an alternate sentence representation, and on Of Employment Letter | Docoments a set of large, artificial corpora with varying levels of ambiguity and synonymy. One difficulty in Archives Excel Templates using machine learning methods for Edol 2012, building natural language interfaces is building the required annotated corpus.
Therefore, we also address this issue by using active learning to reduce the number of training examples required by both WOLFIE and CHILL. Experimental results show that the number of examples needed to Template - Microsoft Excel reach a given level of performance can be significantly reduced with this method. Chen, Chung-Ping. Performance-Driven Interconnect Optimization (dissertation). The University of Texas at Austin, Department of Edol 533:, Computer Sciences. Report# TR-99-10 (dissertation). August 1998. 141 pages. In today's deep submicron designs, interconnect is responsible for 70-80% of the signal delay in Analysis Archives - Microsoft a chip. This is in sharrp contrast to the situation of just a few years ago, when gate delay was the dominant factor in How To Make For A Paper - Academic determining circuit performance, and when interconnect was essentially treated as a delay-free metal wire. Analysis Template Templates. If deep submicron integrated circuits are to excel in yield and performance, the design process must focus on interconnects.
As a result, there is a paradigm shift in design methodology that puts emphasis on interconnect design. Wire sizing, buffer sizing, and Of Employment Offer Letter, buffer insertion are effective techniques to optimize interconnect performance and Template Archives - Microsoft, signal integrity. In this thesis, we present the Global Logistics, results on interconnect optimization based on these techniques. Puchol, Carlos.

Report# TR-99-07 (dissertation). February 1999. 181 pages. Analysis Template Excel. Despite significant progress in realtime systems design in recent years, most research has concentrated on some specific areas such as scheduling, timing analysis or specification. This thesis focuses on the proper definition of the global structure of a realtime system, what it is and and how to integrate all its aspects towards obtaining a complete design that satisfies the specification. Of Employment Letter | Docoments. In this thesis, we consider the problem of providing a general, integrated, and highly automated framework for the design of distributed hardrealtime systems which combines and exploits analytical techniques from individual areas of Template Archives - Microsoft Excel Templates, research. We propose such a framework, which may be thought of as providing a design methodology for the domain of realtime systems. Offer Letter | Docoments Ojazlink. Our proposed methodology is based on three fundamental principles: automation, formalization and generality. We propose a specification language based on Analysis Template these notions and developed from insight on the semantics and How To Make Page For A Research Paper - Academic, experience of the Modechart language (a specification language for realtime systems), also included in Analysis Templates this dissertation.
Current practice in Make A Title Page Writing the design and Template, implementation realtime systems is a largely ad hoc process of trial and error.

Ameliorating the State Explosion Problem. The University of Texas at Austin, Department of Computer Sciences. Report# TR-99-06 (dissertation). February 1999. 155 pages. Systems that maintain an Template - Microsoft Excel ongoing interaction with their environment, such as Operating Systems Network Protocols and Microcontrollers, are commonplace.
The complexity of these systems necessitates a rigorous verification of correct behavior. Automatic verification methods such as Model Checking, while theoretically efficient, suffer in practice from the large state space of these systems, a phenomenon called State Explosion. State explosion often arises when verifying systems parameterized by the number of component processes, and single systems with large data domains. The main contribution of this dissertation is in the development of abstraction methods that serve to ameliorate the Invitation Png And Vector Download, state explosion problem for Analysis Template Archives - Microsoft, such systems. The first part of the dissertation presents abstractions for interesting classes of parameterized systems that reduce the infinite family of instances to a finite-state system, while exactly preserving correctness properties. For parameterized ring systems with a synchronizing token, it suffices to examine a few small instances in order to determine the correctness of News Archives Global Logistics, every instance of the system. The method is applicable to Analysis Excel Templates protocols such as mutual exclusion and Ojazlink, Milner's Cycler. Somewhat surprisingly, the verification problem is undecidable even if the token carries a single bit of information. For parameterized synchronous systems, an Analysis Archives Templates exact abstraction reduces the parameterized system to a finite abstract graph. This abstraction method is applied to the verification of the SAEJ1850 industrial standard bus arbitration protocol.
We also present a general algorithm schema from which algorithms for model-checking several types of infinite-state systems can be derived. The second part of the dissertation presents a proof technique for Make Page Research Paper - Academic Writing, showing that two programs are equivalent up to stuttering (repetition) of states. Stuttering arises when comparing programs that are at different levels of Template Archives - Microsoft, abstraction. The new formulation replaces the global reasoning of earlier techniques with local reasoning, which considerably simplifies abstraction proofs. This new formulation is used in conjunction with a theorem prover to verify a data abstraction for Make A Title Research - Academic, the alternating-bit protocol. Ramachandran, Sowmya. Analysis Archives - Microsoft. Theory Refinement of Bayesian Networks with Hidden Variables. The University of ( Organizational Communications), Texas at Austin, Department of Computer Sciences. Report# AI98-265 (dissertation). Template. May 1998. 129 pages.
Research in theory refinement has shown that biasing a learner with initial, approximately correct knowledge produces more accurate results than learning from data alone. While techniques have been developed to revise logical and connectionist representations, little has been done to Purple Simple Letter Png And Vector Download revise probabilistic representations. Bayesian networks are well-established as a sound formalism for Template, representing and reasoning with probabilistic knowledge, and are widely used. There has been a growing interest in the problem of learning Bayesian networks from data. However, there is no existing technique for learning or revising Bayesian networks with hidden variables (i.e. variables not represented in the data), that has been shown to be efficient, effective, and scalable through evaluation on real data. The few techniques that exist for revising such networks perform a blind search through a large space of revisions, and are therefore computationally expensive. This dissertation presents Banner, a technique for using data to Sample Purchase Agreement - 10+ Examples revise a given Bayesian network with Noisy-Or and Noisy-And nodes, to improve its classification accuracy. Additionally, the initial network can be derived directly from a logical theory expressed as propositional Horn-clause rules. Banner can revise networks with hidden variables, and add hidden variables when necessary. Unlike previous approaches to Analysis Template Archives Excel this problem, Banner employs mechanisms similar to those used in Edol logical theory refinement techniques for using the data to focus the search for Analysis Template Archives - Microsoft Excel Templates, effective modifications to the network.
It can also be used to learn networks with hidden variables from data alone. We also introduce Banner-Pr, a technique for revising the Offer Letter | Docoments, parameters of a Bayesian network with Noisy-Or/And nodes, that directly exploits the computational efficiency afforded by Analysis Template Archives these models. Experiments on several real-world learning problems in domains such as molecular biology and intelligent tutoring systems demonstrate that Banner can effectively and efficiently revise networks to Structure, significantly improve their accuracies, and thus learn highly accurate classifiers. Analysis Excel. Comparisons with the Naive Bayes algorithm show that using the Page For A Research Paper - Academic, theory refinement approach gives Banner a substantial edge over learning from data alone. We also show that Banner-Pr converges faster and produces more accurate classifiers than an - Microsoft existing algorithm for learning the parameters of a network. Estlin, Tara Adrienne. Using Multi-Strategy Learning to Improve Planning Efficiency and Quality. Sample Asset Purchase. The University of Texas at Austin, Department of Computer Sciences.
Report# AI98-269 (dissertation). May 1998. 117 pages. Artificial intelligence planning systems have become an important tool for automating a wide variety of tasks. However, even the most current planning algorithms suffer from two major problems. First, they often require infeasible amounts of computation time to solve problems in most domains. And second, they are not guaranteed to return the best solution to a planning problem, and in fact can sometimes return very low-quality solutions. One way to address these problems is to provide a planning system with domain-specific control knowledge, which helps guide the planner towards more promising search paths. Machine learning techniques enable a planning system to automatically acquire search-control knowledge for different applications. A considerable amount of planning and learning research has been devoted to Analysis Template Archives - Microsoft Excel acquiring rules that improve planning efficiency, also known as speedup learning.
Much less work has been down in learning knowledge to improve the quality of plans, even though this is an essential feature for many real-world planning systems. Furthermore, even less research has been done in acquiring control knowledge to Edol 533: July 2012 improve both these metrics. The learning system presented in this dissertation, called SCOPE, is a unique approach to Analysis Template Archives learning control knowledge for planning. Sample Agreement Examples In Word,. SCOPE learns domain-specific control rules for - Microsoft Templates, a planner that improve both planning efficiency and plan quality, and it is one of the few systems that can learn control knowledge for partial-order planning. SCOPE's architecture integrates explanation-based learning (EBL) with techniques from inductive logic programming. Specifically, EBL is used to constrain an inductive search for control heuristics that help a planner choose between competing plan refinements.
Since SCOPE uses a very flexible training approach, its learning algorithm can be easily focused to prefer search paths that are better for particular evaluation metrics. SCOPE is extensively tested on several planning domains, including a logistics transportation domain and Edol 533: 2012, a production manufacturing domain. In these tests, it is shown to significantly improve both planning efficiency and quality and is shown to be more robust than a competing approach. Califf, Mary Elaine.

132 pages. The recent growth of online information available in the form of Analysis Template Excel Templates, natural language documents creates a greater need for computing systems with the Purple Simple Png And, ability to process those documents to Analysis - Microsoft Templates simplify access to the information. One type of processing appropriate for many tasks is information extraction, a type of text skimming that retrieves specific types of information from text. Although information extraction systems have existed for two decades, these systems have generally been built by hand and contain domain specific information, making them difficult to port to Corporate Communication ( Organizational Structure, Communications) other domains. A few researchers have begun to apply machine learning to information extraction tasks, but most of this work has involved applying learning to pieces of a much larger system. Template Archives. This dissertation presents a novel rule representation specific to natural language and a relational learning system, Rapier, which learns information extraction rules.
Rapier takes pairs of documents and filled templates indicating the information to be extracted and learns pattern-matching rules to Offer | Docoments Ojazlink extract fillers for the slots in the template. The system is tested on several domains, showing its ability to learn rules for different tasks. Rapier's performance is compared to a propositional learning system for Analysis Template - Microsoft Excel Templates, information extraction, demonstrating the superiority of relational learning for some information extraction tasks. Because one difficulty in using machine learning to develop natural language processing systems is the necessity of Purple Invitation Letter Vector For Free, providing annotated examples to supervised learning systems, this dissertation also describes an attempt to reduce the number of examples Rapier requires by employing a form of active learning. Experimental results show that the number of examples required to Archives - Microsoft Templates achieve a given level of Make A Title Page - Academic, performance can be significantly reduced by this method.

This dissertation reports on the compilation of constraint systems into task level parallel programs in a procedural language. This is the only research, of which we are aware, which attempts to generate efficient parallel programs for numerical computations from constraint systems.
Computations are expressed as constraint systems. A dependence graph is News - Hnm Global Logistics derived from the constraint system and a set of Analysis Template Archives, input variables. The dependence graph, which exploits the parallelism in the constraints, is Edol mapped to the target language CODE, which represents parallel computation structures as generalized dependence graphs. Finally, parallel C programs are generated. To extract parallel programs of appropriate granularity, the following features have been included. (i) modularity, (ii) operations over structured types as primitives, (iii) definition of atomic functions. A prototype compiler has been implemented. Archives - Microsoft Excel. The execution environment or software architecture is specified separately from the constraint system.

A common problem in software engineering is Agreement Examples In Word, Pdf efficiently saving the state of application data structures to non-volatile storage between program executions. Template Archives - Microsoft Templates. If this is accomplished using normal file systems, the programmer is Simple Invitation Letter forced to explicitly save the Template Templates, data to files as a stream of uninterpreted bytes, thereby losing both pointer semantics and object identity. A better approach is to use persistent object storage, a natural extension to virtual memory that allows heap data to be saved automatically to disk while maintaining the topology of data structures without any explicit programmer intervention. - Hnm Logistics. If persistent object stores are to replace the functionality of normal file systems, they must be able to address large volumes of data efficiently on standard hardware.
High-performance address translation techniques are necessary and important for supporting large address spaces on Analysis - Microsoft Excel stock hardware. We present pointer swizzling at page fault time ([email protected]), a coarse-grained address translation scheme suitable for this purpose, and demonstrate it by building a persistent storage system for Purple Simple Letter Download, C++ called the Texas Persistent Store. We also discuss alternative approaches for portably incorporating fine-grained address translation in Texas for situations where coarse-grained swizzling alone is insufficient. As part of the performance results, we present a detailed analysis of various components of a coarse-grained address translation technique, including a comparison with overall I/O costs. Pointer swizzling requires run-time knowledge of in-memory object layouts to locate pointers in - Microsoft Excel Templates objects. Edol 533: 2012. We have developed and implemented Run-Time Type Description (RTTD) for Analysis Excel, this purpose; our implementation strategy is portable because it is based on a novel use of compiler-generated debugging information for extracting the necessary type description.
RTTD is also useful for other applications such as data structure browsing, and advanced profiling and tracing.

Consequently, difficult decision problems such as routing traffic, autonomous control, and resource allocation are often unautomated or are only semi-automated using ``rule-of-thumb'' strategies or simple heuristics. This dissertation proposes a general methodology for automating these tasks using techniques from machine learning. Template Archives - Microsoft Templates. Specifically, this research studies the combination of evolutionary algorithms and artificial neural networks to learn and perform difficult decision tasks. Evolutionary algorithms provide an efficient search engine for building decision strategies and require only minimal reinforcement or direction from the environment. Neural networks provide an efficient storage mechanism for the decision policy and can generalize experiences from one situation to another. Simple Png And Vector For Free Download. The learning system developed in this dissertation called SANE contains an evolutionary algorithm specifically tailored to sequential decision learning.

SANE is extensively evaluated and Template Templates, compared to existing decision learning systems and other evolutionary algorithms. Purple Simple Invitation Png And Vector For Free. SANE is shown to Analysis Archives - Microsoft Excel be significantly faster, more robust, and more adaptive in almost every situation. Moreover, SANE's efficient searches return more profitable decision strategies. The flexibility and scope of SANE is demonstrated in two real-world applications.
First, SANE significantly improves the play of a world champion Othello program. Second, SANE successfully forms neural networks that guide a robot arm to Archives - Hnm Global target objects while avoiding randomly placed obstacles.

The parsing of Analysis Template Archives, unrestricted text, with its enormous lexical and structural ambiguity, still poses a great challenge in Vector For Free Download natural language processing. The difficulties with traditional approaches, which try to master the Excel, complexity of parse grammars with hand-crafted rules, have led to a trend towards more empirical techniques. We therefore propose a system for parsing and we choose a deterministic shift-reduce type parser that integrates part-of-speech tagging and syntactic and How To A Title Research Paper, semantic processing, which not only makes parsing very efficient, but also assures transparency during the supervised example acquisition. Applying machine learning techniques, the system uses parse action examples to - Microsoft generate a parser in Purple Invitation Letter Png And For Free Download the form of Template - Microsoft Excel, a decision structure, a generalization of decision trees. To learn good parsing and translation decisions, our system relies heavily on context, as encoded in currently 205 features describing the morphological, syntactical and semantical aspects of a given parse state. Compared with recent probabilistic systems that were trained on 40,000 sentences, our system relies on more background knowledge and a deeper analysis, but radically fewer examples, currently 256 sentences. We test our parser on lexically limited sentences from the Wall Street Journal and achieve accuracy rates of 89.8% for labeled precision, 98.4% for part of speech tagging and How To Make A Title Page For A Research Paper, 56.3% of test sentences without any crossing brackets.

The translation quality was only minimally better (2.2) when starting each translation with the correct parse tree, which indicates that the parser is quite robust and Analysis, that its errors have only a moderate impact on final translation quality. These parsing and translation results already compare well with other systems and, given the Corporate ( Organizational Structure, Communications), relatively small training set and amount of overall knowledge used so far, the results suggest that our system CONTEX can break previous accuracy ceilings when scaled up further. Clancy, Daniel Joseph. Solving Complexity and Ambiguity Problems in Qualitative Simulation.
The University of Texas at Austin, Department of Computer Sciences. Report# AI97-264 (dissertation). December 1997. Analysis Template Archives - Microsoft Excel Templates. 218 pages. Qualitative simulation is 2012 used to Analysis Archives - Microsoft reason about the behavior of imprecisely defined dynamical systems for A Title Paper, tasks such as monitoring, diagnosis, or design.
Often, however, simulation of complex dynamical systems results in either an intractable simulation or an ambiguous behavioral description. These results have caused concern regarding the scalability of techniques based upon qualitative simulation to real--world problems. Two different approaches are used to solve these problems: 1) abstraction and problem decomposition techniques are used during simulation to focus on Analysis relevant distinctions thus reducing the overall complexity of the simulation; and 2) the expressiveness of the modeling language is extended to allow the modeler to In Word, Pdf incorporate additional information. Model decomposition and simulation (DecSIM) uses a component--based simulation algorithm to Template - Microsoft Excel reason about the complex interactions within a sub--system independent of the interactions between subsystems. Variables within the model are partitioned into closely related components and a separate behavioral description is generated for each component. Links are maintained between related components to ensure that all of the Simple Vector For Free Download, constraints in the model are satisfied. Analysis Archives - Microsoft Excel. DecSIM results in exponential speed--up for models that lend themselves to Communication ( Organizational Structure, Communications) decomposition.
Furthermore, DecSIM is guaranteed to generate a behavioral description that is equivalent to Analysis Template Excel Templates the description generated by a standard QSIM simulation modulo the temporal ordering of events for variables in separate components. A common source of irrelevant distinctions within qualitative simulation is Sample Offer | Docoments Ojazlink intractable branching due to chatter. Chatter occurs when the derivative of a variable is constrained only by continuity within a restricted region of the Template Archives Templates, state space. We present two different abstraction techniques that completely eliminate the problem of chatter by Make A Title Page For A Research Paper - Academic Writing abstracting a chattering region into a single abstract state. Archives - Microsoft Templates. Both techniques retain the QSIM soundness guarantee and eliminate all instances of chatter without over--abstracting. To address the problem of an ambiguous behavioral description, Temporally Constrained QSIM (TeQSIM) integrates temporal logic model checking into the qualitative simulation process allowing the modeler to specify behavioral information via trajectory constraints. Trajectory constraints, specified using an extension of a propositional linear--time temporal logic, can be used to focus the simulation, simulate non--autonomous systems and reason about boundary condition problems.

December 1997. 442 pages. Dynamic memory management is Corporate ( Organizational Communications) a very important feature of modern programming languages, and - Microsoft Excel, one that is often taken for granted. Programmers frequently place great demands on the memory management facilities of their language, and expect the Sample Letter | Docoments, language to efficiently handle these requests.

226 pages. An important goal of a distributed system is to effectively utilize the collective resources of the Template Archives, system, namely, the Sample Of Employment Offer Letter Ojazlink, memory and the processors of the Archives Excel Templates, individual nodes. This dissertation addresses certain problems pertaining to sharing memory and processors in distributed systems. In the first part of the dissertation, we study two important issues that arise while sharing memory in July 2012 a distributed system: memory contention and Analysis Template Archives - Microsoft Templates, faults. Purple Simple Png And Vector For Free. We adopt a model of Template Excel, computation in which each node can send or receive at most a constant number of objects per step. Our main result is a simple protocol for providing fast access to shared objects in an environment in A Title Writing which memory contention is Templates unconstrained and a constant fraction of the nodes and communication links may be faulty at any time. Our protocol combines techniques for hashing and erasure codes with a new mechanism for on-line replication.
We show that if each new access request is chosen according to a fixed probability distribution over the set of objects, then our protocol rapidly reaches a steady state in which each request is satisfied in an expected constant number of steps and Agreement - 10+, the throughput of the Excel, protocol is asymptotically optimal. We also prove that the protocol continues to remain in a steady state if changes in How To A Title Paper the access pattern are moderate. The second part of the dissertation studies load balancing, which is a mechanism for sharing processors in a distributed system. We analyze the effectiveness of a local load balancing algorithm in which each node repeatedly balances its load with its neighbors. Excel Templates. Our main results concern the static version of the Corporate Communication Structure,, problem where we assume that the total load does not change with time. We analyze the Archives Templates, local balancing algorithm in terms of both the imbalance of the initial load distribution and several parameters of the How To Paper Writing, network, including the number of nodes, the maximum degree, and the edge expansion. Template Templates. We show that the algorithm is worst-case optimal for Sample Asset Purchase Agreement In Word,, all networks. We improve this result for the special case of ring networks by showing that the local balancing approach is optimal (up to an additive linear term) for every initial distribution of load on the ring. Our results are also shown to hold for an asynchronous model of computation.
This dissertation demonstrates that a number of basic resource sharing problems admit efficient solutions in the form of simple local algorithms. Our algorithms are simple in the sense that the program running at Archives Excel Templates, each node can be expressed as a periodic process that repeatedly executes a small number of fixed operations. Our algorithms are local in the sense that each node either communicates with only its nearest neighbors or sends messages to only a small number of other nodes. Hermjakob, Ulf. Ojazlink.

The parsing of unrestricted text, with its enormous lexical and structural ambiguity, still poses a great challenge in natural language processing. The difficulties with traditional approaches, which try to master the complexity of parse grammars with hand-crafted rules, have led to a trend towards more empirical techniques. We therefore propose a system for parsing and translating natural language that learns from examples and uses some background knowledge.

Report# TR-97-03 (dissertation). January 24, 1997. 346 pages. Graphs play an Corporate Structure, important role in modeling the underlying structure of many real world problems. In this thesis, we investigate several interesting graph problems. The first part of this thesis focuses on Analysis Archives Excel the problem of finding a smallest set of edges whose addition makes an input undirected graph satisfy a given connectivity requirement.
This is Edol July 2012 a fundamental graph theoretic problem that has a wide variety of applications in designing reliable networks and database systems. We have obtained efficient sequential and parallel algorithms for finding smallest augmentations to satisfy 3-edge-connectivity, 4-edge-connectivity, biconnectivity, triconnectivity, and four-connectivity. Our parallel algorithms are developed on the PRAM model. Our approach in obtaining these results is to first construct a data structure that describes all essential information needed to augment the input graph, e.g., the set of all separating sets and Analysis Template Archives - Microsoft Excel, the set of all maximal subsets of vertices that are highly connected. Based on this data structure, we obtain a lower bound on the number of edges that need to be added and prove that this lower bound can be always reduced by Edol July one by Template Archives - Microsoft Templates properly adding an edge. The second part of the thesis focuses on the implementation of PRAM-based efficient parallel graph algorithms on News Archives Global a massively parallel SIMD computer. This work was performed in two phases.
In the first phase, we implemented a set of parallel graph algorithms with the constraint that the size of the input cannot be larger than the number of Analysis Template - Microsoft Excel Templates, physical processors. For this, we first built a kernel which consists of commonly used routines. Agreement - 10+ Examples Pdf. Then we implemented efficient parallel graph algorithms by calling routines in the kernel. In the second phase, we addressed and solved the issue of allocating virtual processors in our programs. Under our current implementation scheme, there is no bound on the number of virtual processors used in the programs as long as there is enough memory to store all the data required during the computation. The performance data obtained from Template Archives Excel extensive testing suggests that the extra overhead for simulating virtual processors is moderate and the performance of our code tracks theoretical predictions quite well.

The University of Texas at Austin, Department of Computer Sciences. Report# AI96-249 (dissertation). December 1995. 121 pages. Designing computer systems to understand natural language input is a difficult task. Of Employment Offer. In recent years there has been considerable interest in corpus-based methods for constructing natural language parsers.
These empirical approaches replace hand-crafted grammars with linguistic models acquired through automated training over language corpora. A common thread among such methods to date is the use of Analysis Template - Microsoft Excel, propositional or probabilistic representations for the learned knowledge. This dissertation presents an alternative approach based on techniques from a subfield of machine learning known as inductive logic programming (ILP). ILP, which investigates the learning of relational (first-order) rules, provides an Sample Offer Letter empirical method for acquiring knowledge within traditional symbolic parsing frameworks. This dissertation details the architecture, implementation and Template - Microsoft Excel Templates, evaluation of CHILL, a computer system for acquiring natural language parsers by training over corpora of parsed text. CHILL treats language acquisition as the learning of search-control rules within a logic program that implements a shift-reduce parser. Control rules are induced using a novel ILP algorithm which handles difficult issues arising in the induction of 2012, search-control heuristics. Both the control-rule framework and the induction algorithm are crucial to Analysis Excel Templates CHILL'S success. The main advantage of CHILL over Corporate Communication Structure,, propositional counterparts is its flexibility in handling varied representations.
CHILL has produced parsers for various analyses including case-role mapping, detailed syntactic parse trees, and a logical form suitable for expressing first-order database queries. All of these tasks are accomplished within the same framework, using a single, general learning method that can acquire new syntactic and semantic categories for resolving ambiguities. Experimental evidence from - Microsoft both artificial and real-world corpora demonstrates that CHILL learns parsers as well or better than previous artificial neural network or probabilistic approaches on comparable tasks. In the database query domain, which goes beyond the scope of previous empirical approaches, the learned parser outperforms an existing hand-crafted system. These results support the claim that ILP techniques as implemented in CHILL represent a viable alternative with significant potential advantages over neural-network, propositional, and Global Logistics, probabilistic approaches to Analysis Archives - Microsoft Excel Templates empirical parser construction.

This dissertation describes research to extend and improve the Spatial Semantic Hierarchy (SSH) approach to robot exploration and Invitation Vector Download, mapping, and to demonstrate and evaluate its effectiveness in controlling physical mobile robots.

Report# AI96-258 (dissertation). December 1996. 143 pages. This dissertation describes methods for simulating and refining imprecisely-defined Ordinary Differential Equation (ODE) systems. When constructing a model of a physical process, a modeler must cope with uncertainty due to incomplete knowledge of the process. For tasks such as design and diagnosis, the effects of this uncertainty must be considered. Analysis Template Excel Templates. However, predicting the behavior of an imprecisely-defined model is not easy since the model covers a space of many precise instances, each of Purple Invitation Letter Download, which behaves differently. While model uncertainty cannot be completely eliminated, it is possible to Analysis - Microsoft Templates reduce it. Model refinement uses observations of a physical process to rule out portions of the model space that could not have produced the observations. As more experience with the physical process is Communication Communications) gained, the imprecision in the model is further reduced.
This dissertation describes three methods for reasoning with imprecise ODE models. SQsim is a simulator that produces a guaranteed bound on the behavior of an imprecise ODE model. By using a multiple-level representation and inference methods that span the qualitative-to-quantitative spectrum, SQslM produces predictions whose uncertainty is Analysis Template Archives Excel consistent with model imprecision. We demonstrate SQsim on Corporate ( Organizational Structure, a complex, nonlinear chemical process and compare it to other methods for simulating imprecise ODE models.

It uses a neural- network inspired model and nonlinear constrained optimization to search a space of monotonic functions.
We prove that MSQUID can estimate any monotonic function and show that it produces better estimates than does unconstrained optimization . SQUID, which uses SQsim and MSQUID as components, is a system identification method that refines an imprecise model using a stream of observations from Ojazlink a physical process. SQUID uses refutation to rule out portions of the model space that are inconsistent. Mahoney, Ph.D., J. Jeffrey.

The University of Corporate Communication ( Organizational, Texas at Austin, Department of Computer Sciences. Report# AI96-260 (dissertation). May 1996. 100 pages. This research describes the system RAPTURE, which is designed to revise rule bases expressed in certainty-factor format. Recent studies have shown that learning is facilitated when biased with domain-specific expertise and Archives, have also shown that many real-world domains require some form of probabilistic or uncertain reasoning in order to Purple Simple Letter Png And For Free Download successfully represent target concepts.
RAPTURE was designed to take advantage of both of these results. Beginning with a set of certainty-factor rules, along with accurately-labeled training examples RAPTURE makes use of both symbolic and connectionist learning techniques for revising the rules in Analysis Archives - Microsoft Excel Templates order that they correctly classify all of the training examples. A modified version of backpropagation is used to adjust the certainty factors of the rules ID3's information-gain heuristic is used to add new rules and Edol 533: July 2012, the Upstart algorithm is Analysis Template - Microsoft used to ( Organizational Communications) create new hidden terms in the rule base.

We apply register relocation techniques during the clustering of registers and - Hnm Global Logistics, combinational modules to minimize the number of Archives, FPGA logic modules. This problem is exactly solved by modeling it as a linear program, following a sophisticated transformation from an Edol 2012 integer nonlinear program.
Our third topic deals with feed-through pin assignment for routing of standard-cell designs. It is a necessary process between global routing and detailed routing. We present an Template Archives Excel optimal algorithm for single row feed-through pin assignment under some reasonable constraints. It transform the original problem to How To A Title Page Research Paper - Academic a path problem on Analysis Templates a special graph. News - Hnm Global Logistics. The exact single row algorithm serves as the basic procedure in an iterative algorithm for the multiple row feed-though pin assignment. The fourth problem is clock net routing.

Finally, we consider partitioning clock pins into clusters aiming to Offer Ojazlink minimize and balance the capacitive load of each cluster of clock pins. This preprocessing step for buffered clock tree routing can greatly reduce the effort in post-routing load balancing by adjusting wire widths or lengths.

This work will focus on Global a particular mechanical verification technique, model checking, in the context of a specific specification language environment, RTL and Modechart. RTL is a first order logic for reasoning about the Template Archives Excel Templates, times of occurrences of system events. Modechart is a specification language introduced to organize RTL specifications. Model checking can be used to show that every computation of a Modechart specification satisfies a property specified in RTL. Letter For Free Download. Computation graphs will be introduced to represent the set of all computations of a Modechart specification for model checking. Template Archives - Microsoft. Decision procedures for a number of classes of RTL formulas with respect to Modechart specifications will also be introduced. One of the disadvantages of model checking as a verification technique is that it is extremely susceptible to the state explosion problem. News - Hnm Global Logistics. One focus of this work is presenting different techniques for mitigating the state explosion problem. These include substituting computation graph reachability queries for more complex RTL formulas, using monitor modes, using partial computation graphs, exploiting determinism, and using simulation-verification.

A Self-Organizing Neural Network Model Of The Primary Visual Cortex. The University of Texas at Austin, Department of Computer Sciences. Report# AI95-237 (dissertation). August 1995. This work is aimed at modeling and analyzing the computational processes by which sensory information is learned and represented in the brain. First, a general self-organizing neural network architecture that forms efficient representations of visual inputs is presented. Two kinds of visual knowledge are stored in the cortical network: information about the principal feature dimensions of the visual world (such as line orientation and ocularity) is stored in the afferent connections, and correlations between these features in the lateral connections. During visual processing, the cortical network filters out these correlations, generating a redundancy-reduced sparse coding of the visual input. Through massively parallel computational simulations, this architecture is shown to give rise to structures similar to those in the primary visual cortex, such as (1) receptive fields, (2) topographic maps, (3) ocular dominance, orientation and size preference columns, and (4) patterned lateral connections between neurons. The same computational process is Archives - Microsoft shown to account for many of the dynamic processes in the visual cortex, such as reorganization following retinal and cortical lesions, and Archives Global Logistics, perceptual shifts following dynamic receptive field changes. These results suggest that a single self-organizing process underlies development, plasticity and visual functions in the primary visual cortex.

The University of Texas at Austin, Department of Offer Letter Ojazlink, Computer Sciences. Report# AI95-239 (dissertation). December 1995. 128 pages. As systems like chemical plants, power plants, and automobiles get more complex, online diagnostic systems are becoming increasingly important. One of the ways to rein in Archives Templates the complexity of News Archives - Hnm, describing and reasoning about large systems such as these is to describe them using qualitative rather than quantitative models. Model-based diagnosis is a class of diagnostic techniques that use direct knowledge about how a system functions instead of expert rules detailing causes for every possible set of symptoms of a broken system. Template Excel. Our research builds on standard methods for model-based diagnosis and extends them to the domain of complex dynamic systems described using qualitative models.
We motivate and describe our algorithm for diagnosing faults in a dynamic system given a qualitative model and a sequence of Sample Of Employment Offer Letter | Docoments, qualitative states. The main contributions in this algorithm include a method for propagating dependencies while solving a general constraint satisfaction problem, and a method for verifying the compatibility of a behavior with a model across time. The algorithm can diagnose multiple faults and uses models of faulty behavior, or behavioral modes. We then demonstrate these techniques using an implemented program called QDOCS and test it on some realistic problems. Through our experiments with a model of the reaction control system (RCS) of the space shuttle and with a level-controller for Analysis Archives Excel Templates, a reaction tank, we show that QDOCS demonstrates the best balance of generality, accuracy and efficiency among known systems.

The University of Edol, Texas at Austin, Department of Computer Sciences. Report# AI95-241 (dissertation). Template Archives - Microsoft Templates. December 1995. 224 pages. Purchase Agreement Examples In Word,. Spatial reasoning is an essential part of human interaction with the physical world. Of the many models that have been developed to support automated spatial reasoning, most rely on numerical descriptions of a spatial scene. This dissertation addresses problems where only qualitative descriptions of a spatial scene are available, such as natural language understanding, qualitative design, and physics problem solving. We provide the first set of solutions, given only a qualitative description of a spatial scene, for reasoning about Template - Microsoft dynamic change in both the spatial and non-spatial properties of a physical system. We use diagrams to compactly input the spatial scene for a problem, and text to describe any non-spatial properties. To match diagram and text objects so their descriptions can be integrated, we have developed a method for describing the conceptual class of objects directly in diagrams.
Then, diagram and text objects can be matched based on their conceptual class. The given problem is solved through qualitative simulation, and all spatial reasoning is done with respect to an extrinsic Cartesian coordinate system. We model the relative positions of objects through inequality constraints on the coordinates of the points of interest. Asset Purchase Examples In Word, Pdf. Changes due to translational motion are detected by noting changes in the truth values of inequality constraints. We model the orientation of an object through knowledge of its extremal points and its qualitative angle of rotation with respect to each coordinate axis. This model has been used to reason qualitatively about the effects of rotational motion, such as changes in the area projected by one object onto another. We have implemented our spatial representation as production rules and as model fragments in the QPC qualitative modeling system.
The former has been used for solving static-world problems such as understanding descriptions of an urban scene. The latter has been used to reason about situations where changes in spatial properties play a critical role, such as the operation of transformers, oscillators, generators, and motors. To support dynamic spatial reasoning, we have expanded the modeling capabilities of QPC to Template Archives - Microsoft Excel include methods for modeling piecewise-continuous variables, non-permanent objects, and variables with circular quantity spaces. Murray, Kenneth S. Learning as Knowledge Integration. The University of Texas at Austin, Department of Computer Sciences. Report# TR-95-41 (dissertation). November 1995. 300 pages. A fundamental challenge for Artificial Intelligence is - Hnm Global developing methods to build and maintain knowledge-based systems.
Knowledge integration is the task of identifying how new and prior knowledge interact while incorporating new information into a knowledge base. This task is pervasive because substantial knowledge bases must be developed incrementally: segments of Analysis Template Archives Excel Templates, knowledge are added separately to a growing body of knowledge. This task is difficult because new and prior knowledge may interact in very subtle and surprising ways, and unanticipated interactions may require changes to the knowledge base. Performing knowledge integration involves determining and How To Page For A - Academic, effecting these changes. This research investigates knowledge integration as a machine learning task. Its contributions include formalizing knowledge integration as a machine learning task, developing a computational model for performing knowledge integration, and instantiating the computational model as an implemented machine learning program. The study of knowledge integration and methods that perform it is important both for Analysis - Microsoft Excel, pragmatic concerns of building knowledge-based systems and for theoretical concerns of understanding learning systems. By identifying subtle conflicts and gaps in knowledge, knowledge integration facilitates building knowledge-based systems. By avoiding unnecessary restrictions on learning situations, knowledge integration reveals important sources of learning bias and permits learning behaviors that are more opportunistic than do traditional machine learning tasks. REACT is a computational model that identifies three essential activities for Communication ( Organizational, performing knowledge integration. Elaboration assesses how new and prior knowledge interact.
The system's limited capacity to explore the interactions of new and prior knowledge requires methods to focus its attention. This focus is achieved by restricting elaboration to consider only selected segments of prior knowledge. Recognition selects the prior knowledge that is considered during elaboration. By identifying the consequences of new information for relevant prior knowledge, recognition and elaboration reveal learning opportunities, such as inconsistencies and gaps in the extended knowledge base. Adaptation exploits these learning opportunities by Analysis Template Archives - Microsoft Excel modifying the new or prior knowledge. - Hnm Global Logistics. KI is a machine learning program that implements the REACT model. Template - Microsoft Excel. Empirical studies demonstrate that KI provides significant assistance to knowledge engineers while integrating new information into a large knowledge base.

This dissertation addresses the problem of Archives Templates, creating interactive graphical programming environments for visual programming languages that are based on directed graph models of computation. Sample Letter | Docoments. Such programming environments are essential to using these languages but their complexity makes them difficult and Analysis - Microsoft Excel Templates, time consuming to construct. The dissertation describes a high level specification language, Glide, for defining integrated graphical/textual programming environments for such languages. It also describes the Simple Letter Png And Vector, design of Template Excel, a translation system, Glider, which generates an executable representation from specifications in Sample Offer the Glide language. Glider is a programming environment generator; it automates the task of creating the programming environments used for Template Templates, developing programs in graphbased visual languages.
The capabilities supported by the synthesized programming environments include both program capture and animation of executing programs. Sample Of Employment | Docoments Ojazlink. The significant concepts developed for this work and embodied in the abstractions provided by the Glide language are: an approach to Analysis Template - Microsoft treating programs as structured data in a way that allows an integrated representation of graph and text structure; a means to navigate through the structure to identify program components; a query language to concisely identify collections of components in the structure so that selective views of program components can be specified; a unified means of representing changes to the structure so that editing, execution, and animation semantics associated with the Edol 2012, language can all be captured in a uniform way; and a means to associate the graphical capabilities of user interface libraries with displaying components of the language. The data modeling approach embodied in the Glide specification language is a powerful new way of representing graph-based visual languages. Template Excel. The approach extends the traditional restricted mechanisms for Communication ( Organizational, specifying composition of text language structure. The extensions allow programming in visual languages to be expressed as a seamless extension of programming in text-based languages. A data model of a graph-based visual language specified in Glide forms the basis for specifying the program editing, language execution semantics, and program animation in a concise and abstract way.

As the applications of production systems expand from traditional artificial intelligence domains into the data intensive and real-time arenas, program complexity and the volume of Template Archives Templates, data also increase dramatically. Over a decade of efforts to exploit this opportunity, the previous approaches of employing parallel match and/or syntactic based multiplc-rulc-firing have failed to Corporate ( Organizational Structure, raise the performance to a satisfactory level. Based on Analysis Excel the observations made in News Archives Logistics a pilot study, we found that by Template Archives - Microsoft Templates incorporating application semantics, it is possible to achieve a much higher level of concurrency than what can be achieved by traditional techniques. This dissertation presents a new approach called decomposition abstraction that aims at the exploration of application parallelism in production systems.
Decomposition abstraction is the process of organizing and specifying parallel decomposition strategies. We propose a general object-based framework and present the formal semantics of a set of decomposition abstraction mechanisms that are applicable to any rule language. A semantic-based dependency analysis technique that uncovers hidden concurrency based on a new notion of Sample Of Employment | Docoments Ojazlink, functional dependency successfully derives parallelism that is very difficult, if not impossible, to discover by traditional syntactic analysis techniques. The effectiveness of our approach is validated both by simulation and implementation on Analysis Template - Microsoft Templates Sequent Symmetry multiprocessor. The performance results demonstrate the potential of the decomposition abstraction approach to achieve linear and scalable speedup. Kartha, G. Neelakantan.

167 pages. Analysis Template - Microsoft Excel. Reasoning about actions is a central area of research in artificial intelligence, related to the study of commonsense and nonmonotonic reasoning, knowledge representation, planning and theorem proving. The methodology of research in this area has not been quite satisfactory; typically, a new proposal for reasoning about actions is Edol 533: July 2012 illustrated by way of a few examples that have been known to be challenging to formalize, and then claims are made that the method works in general. This is not very satisfactory since minor modifications of the examples might prove (indeed, have proven, in many cases) to be difficult or impossible for the new proposal to handle correctly. Such an example-oriented methodology also makes it difficult to compare various formalisms and thus to synthesize new ones. In this dissertation, we present a systematic study of reasoning about Archives - Microsoft Templates actions. Edol July 2012. The shortcomings of the example-oriented methodology are avoided as follows. First, declarative languages for describing actions are introduced and their semantics defined in such a way as to capture the underlying commonsense intuitions.
Different methods of reasoning about actions are presented as translations from Analysis Template Archives - Microsoft Templates these languages and then the adequacy of the different formalizations is established by proving the Make A Title Page Research Writing, soundness and completeness of the translations. The new declarative languages we propose are capable of representing rich action domains, such as those where actions can have indirect effects. In addition, we introduce a new approach to Analysis Template Archives - Microsoft reasoning about Edol 533: July actions and show its adequacy in Archives - Microsoft formalizing a large class of action domains. We show that, in conjunction with this approach, symbolic methods can often be employed for automating reasoning about actions. Finally, we point out some limitations of proposed methods of reasoning about actions and How To Page, suggest ways to overcome these limitations.

The research with VISOR aims at three general goals: (1) to Archives - Hnm contribute to building robust, general vision systems that can be adapted to different applications, (2) to Archives - Microsoft Excel contribute to a better understanding of the human visual system by Edol modeling high-level perceptual phenomena, and (3) to address several fundamental problems in neural network implementation of Archives - Microsoft Excel Templates, intelligent systems, including resource-limited representation, and representing and learning structured knowledge. These goals lead to a schema-based approach to Communications) visual processing, and focus the Analysis Template Archives - Microsoft Templates, research on the representation and learning of visual schemas in neural networks. Given an input scene, VISOR focuses attention at one component of an object at a time, and extracts the shape and position of the component. The schemas, represented in a hierarchy of maps and connections between them, cooperate and compete to Offer determine which one best matches the input. VISOR keeps shifting attention to other parts of the scene, reusing the same schema representations to Template Templates identify the objects one at a time, eventually recognizing what the scene depicts. The recognition result consists of Communications), labels for the objects and the entire scene. VISOR also learns to encode the schemas' spatial structures through unsupervised modification of Analysis Archives - Microsoft, connection weights, and reinforcement feedback from the environment is Sample Agreement - 10+ Examples Pdf used to determine whether to adapt existing schemas or create new schemas to represent novel inputs. VISOR's operation is based on cooperative, competitive, and parallel bottom-up and top-down processes that seem to underlie many human perceptual phenomena. Excel Templates. Therefore, VISOR can provide a computational account of ( Organizational Communications), many such phenomena, including shifting of Analysis Archives, attention, priming effect, perceptual reversal, and circular reaction, and may lead to How To Make A Title Paper - Academic Writing a better understanding of how these processes are carried out in the human visual system. Compared to traditional rule-based systems, VISOR shows remarkable robustness of recognition, and is able to indicate the confidence of its analysis as the inputs differ increasingly from the schemas.

Report# TR-94-33 (dissertation). September 10, 2003. 183 pages. This research explored the understanding that novice computer science students have of mathematical logic.
Because concepts of logic are at the heart of Edol 2012, many areas of computer science, it was hypothesized that a solid understanding of - Microsoft, logic would help students grasp basic computer science concepts more quickly and would better prepare them for advanced topics such as formal verification of program correctness. This exploratory study lays the groundwork for further investigation of this hypothesis. Data for the study were the publicly available versions of the Advanced Placement Examination in Computer Science (APCS examination) and files containing anonymous individual responses of students who took these examinations. Invitation Png And For Free. A content analysis procedure was developed to provide reliable and valid classification of multiple-choice items from the Analysis Template Archives, APCS examinations based on the relationship between concepts covered in each item and the concepts of logic. Corporate. The concepts in the computer science subdomain of logic were clarified by means of a taxonomy developed for use in this study. Thirty-eight experts in computer science education were judges in the content analysis of the multiple-choice items. The judges' ratings provided criteria for grouping items into Template Archives Templates strongly related and not strongly related partitions. In general, the mean proportion of student respondents that correctly answered the items in a partition was lower for the strongly related than for the not strongly related partition, with a smaller standard deviation.
The difficulty distributions for the two partitions were shown to be non-homogeneous (p ! .002), with the difficulty distribution for the strongly related partition skewed more towards the very difficult end of the distribution. The results of this study suggest that novice computer science students experience more difficulty with concepts involving mathematical logic than they do, in Purple Simple Letter For Free general, with other concepts in Analysis Template - Microsoft Excel computer science. This indicates a need to improve the way in which novice computer science students learn the concepts of logic. Purchase Agreement Examples Pdf. In particular, pre-college preparation in mathematical logic and the content of discrete mathematics courses taken by computer science students need to be scrutinized. Suel, Torsten. Template.

197 pages. This thesis studies the problems of packet routing and sorting on parallel models of computation that are based on Sample Offer Letter Ojazlink a fixed, bounded-degree topology. It establishes lower bounds for several classes of sorting networks and algorithms, and describes techniques and algorithms for packet routing and sorting on mesh-connected and related networks. A lower bound of Omega(lg n lglg n / lglglg n) is established for the depth of shuffle-unshuffle sorting networks, a class of sorting networks that maps efficiently to the hypercube and its bounded-degree variants. Analysis - Microsoft Templates. A stronger lower bound of Omega(lg^2 n / lglg n) is shown for a subclass of the shuffle-unshuffle sorting networks whose structure corresponds to the class of ascend and descend algorithms on the hypercube. These lower bounds also extend to restricted classes of non-oblivious sorting algorithms on hypercubic networks. How To A Title Page For A Research. A lower bound of Analysis Templates, Omega(n (lg n / lglg n)^2) is shown for the size of Shellsort sorting networks, and for the running time of Asset Purchase, non-oblivious Shellsort algorithms. The lower bound establishes a trade-off between the running time of a Shellsort algorithm and the length of the underlying increment sequence. Template Excel Templates. For the problems of permutation routing and sorting on meshes and - Hnm, related networks, a set of Template Archives, techniques is proposed that can be used to convert many randomized algorithms into deterministic algorithms with matching running time and queue size. Applications of these techniques lead to ( Organizational Communications) a deterministic algorithm for sorting on the two-dimensional mesh that achieves a running time of 2n+o(n), and a fairly simple deterministic algorithm for routing with a running time of 2n+o(n) and very small queue size. Some other applications of the techniques are also described.
Finally, the thesis gives algorithms and lower bounds for routing and sorting on multi-dimensional meshes and meshes with bus connections. Lee, Wood Wai.

Shortcomings of qualitative simulation, and of quantitative simulation, motivate combining them to do simulations exhibiting strengths of each. The resulting class of - Microsoft Excel Templates, techniques is termed qualitative-quantitative simulation . Qualitative-quantitative simulation is made more challenging-yet more useful- by accounting for partial quantitative information. Available quantitative information is Purple Invitation Png And Vector Download often incomplete, so allowing numerical values to be qualified with error terms or tolerances expressed as intervals is important. In this research, we demonstrate the combination of qualitative and quantitative simulation in an implemented system called Q3. Analysis Archives Excel Templates. Q3 utilizes complete or incomplete quantitative information, progressively refining a qualitative simulation in a process that provides increasingly specific numeric predictions. The step size refinement algorithm is central to Q3. Step size refinement is discussed with respect to three properties often used in analyzing simulation algorithms: correctness of the inferences, theoretical convergence to the true solution, and Sample Offer Letter | Docoments, stability of solutions when the model parameters and Template, initial conditions are incompletely specified. Communication ( Organizational Structure, Communications). Q3 has been successfully applied to model based prediction, measurement interpretation diagnosis, and finding probabilities of qualitative behaviors. Franke, David Wayne. A Theory of Teleology.
The University of Texas at Austin, Department of Computer Sciences. Report# AI93-201 (dissertation). May 1993. 188 pages. A representation language for teleological descriptions, or descriptions of purpose, is defined.
The teleological language, TeD, expresses the descriptions of purpose in terms of design modifications that guarantee the satisfaction of Analysis Template - Microsoft Templates, design specifications. These specifications express potential behaviors the designed artifact should or should not exhibit. We define an abstraction relation on behavior and implement model checking and classification algorithms that compute this abstraction relation. The model checking algorithm determines whether or not a behavior satisfies a specification. The classification algorithm provides effective indexing of Asset Purchase - 10+ Pdf, behaviors and teleological descriptions. We implement an acquisition technique for teleological descriptions and demonstrate how teleological descriptions can subsequently be used in diagnosis, explanation, case-based reasoning, design by analogy, and design reuse.
We demonstrate the behavior language, teleology language, acquisition of teleological descriptions, and application of teleological descriptions in explanation, diagnosis, and design reuse via examples in the thermal, hydraulic, electrical, and - Microsoft Templates, mechanical domains. We define additional teleological operators that express purposes like prevent, order, synchronize, maintain, and regulate, demonstrating the ability to represent common human-generated descriptions of purpose in TeD. Expressing the purpose of preventing an undesirable behavior is unique to TeD, and is an Edol July 2012 example of TeD's ability to Template Templates express purposes regarding missing behaviors and components removed from a design. The teleology language developed in Purple Invitation Letter Png And this work represents a significant advance over previous work by providing a formal language that 1) is independent of any particular domain of mechanisms or behavior language, 2) can be effectively acquired during the design process, and 3) provides an effective means of classifying and indexing teleological descriptions.

Temporal and Spatial Analysis in Analysis Template Templates Knowledge-based Physics Problem Solving. Corporate ( Organizational Structure,. The University of Texas at Austin, Department of Computer Sciences. Report# AI93-205 (dissertation). December 1992. 266 pages. Physics problems as stated in textbooks are typically informal and incomplete, and not amenable to the direct application of the general laws of physics. In this dissertation, we present a theory of analysis for automatically solving such problems.
In particular, the theory provides a detailed methodology for constructing a formal problem representation, called physical representation, upon which physics laws may be appropriately selected and instantiated. With the equations generated by these laws, the Template Archives Excel, solutions to these problems are obtained through strictly mathematical manipulations. This theory provides a well-structured domain language, in which it is relatively easy to state mechanical knowledge and mechanics problems. In the language we introduce the notion of basic physical phenomenon for representing the knowledge of physical situations and events. ( Organizational Structure,. This notion serves as both the Analysis Template Templates, building block for the physical representation and as a vehicle for accessing the appropriate physical laws.

This dual-system representation facilitates bi-level abstractions of Invitation Png And For Free Download, time necessary to Analysis - Microsoft Excel avoid discontinuities introduced by short impulsive phenomena, e.g., collisions, and corresponds well with human-like temporal reasoning. The language also includes an ontology of space, using multiple abstractions to How To A Title Research Paper Writing account for its inherent complexity, and representation schemes for physical laws and equations. The other key ingredient of the Analysis Template Excel Templates, theory is a repertoire of ordered knowledge sources, formulated to specify the derivation procedures of a physical representation.

This dissertation presents an Purple Invitation Png And For Free Download approach to automated reasoning about physical systems in the presence of incomplete knowledge which supports formal analysis, proof of guarantees, has been fully implemented, and applied to substantial domain modeling problems. Predicting and reasoning about the behavior of physical systems is Template a difficult and important task that is essential to everyday common sense reasoning and to complex engineering tasks such as design, monitoring, control, or diagnosis.
A capability for Invitation Letter Download, automated modeling and simulation requires - expressiveness to represent incomplete knowledge - algorithms to draw useful inferences about non-trivial systems, and - precise semantics to Analysis Template Archives Templates support meaningful guarantees of correctness In order to clarify the structure of the knowledge required for reasoning about the behavior of physical systems, we distinguish between the Edol 533:, model building task which builds a model to describe the system, and the simulation task which uses the model to Archives - Microsoft Templates generate a description of the Offer Letter | Docoments Ojazlink, possible behaviors of the system. This dissertation describes QPC, an implemented approach to Template Archives - Microsoft reasoning about physical systems that builds on the expressiveness of Qualitative Process Theory [Forbus,1986] and the mathematical rigor of the QSIM qualitative simulation algorithm [Kuipers,1986]. The semantics of QPC's modeling language are grounded in Edol 533: July the mathematics of ordinary differential equations and their solutions. Analysis Template Archives - Microsoft Excel. This formalization enables the statement and proof of QPC's correctness.

Report# TR-93-20 (dissertation). November 1993. 207 pages. Much of the complexity of concurrent program design lies in the specification of patterns of communication: flows of information among objects (e.g. processes) expressed as functions of the global computation state. Underlying the communication mechanisms of every concurrent system is Analysis Template Archives Excel a naming system, whic is used to specify the objects participating in each communication. Simple Invitation Vector Download. We call those characteristics of naming systems that determine the patterns of Template Archives - Microsoft Excel, communication that can be specified the communication semantics of naming systems.
A more expressive naming system allows communication to be specified at a higher level of abstraction. Purple Invitation Letter Png And For Free Download. The available communication abstractions are significant in the choice of an algorithm, in which specific patterns of Archives - Microsoft Excel, communication are manifest, to solve a particular problem. Thus the choice or design of a naming system often significantly affects the design of concurrent programs. Yet naming systems have not been widely studied as independent components of concurrent systems. This has led to empirical design and inappropriate choices of naming systems, which hinder the Communication ( Organizational Structure, Communications), specification of complex patterns of Template Excel Templates, communication and How To For A, constrain algorithm design, yielding awkward programs and inefficient executions. To simplify the Analysis - Microsoft Templates, use of Corporate ( Organizational Structure,, naming systems in specifying communication, and to make more precise our understanding of their communication semantics, we adopt a two fold approach: The development of a formal taxonomy of naming systems, and the design of a specific naming system and communication primitive, called Associative Broadcast, that enable straightforward specification of complex communication patterns. The taxonomy defines a set of orthogonal properties that characterize the ability ofnaming systems to express fundamental patterns of communication. Naming systems are classified and ranked in a partially ordered hierarchy according to their properties. The hierarchy allows systematic comparison of naming systems, and selection of naming systems for Template Excel Templates, the solution of problems requiring specific properties. Associative Broadcast resides at the top of the hierarchy, and allows the specification of a dynamic, descriptively named target set of objects as the destination of a message by defining names to be propositional expressions over Sample Offer Ojazlink, sets of object attributes, and by using delayed resolution.
We apply Associative Broadcast to obtain algorithms with desirable symmetry, robustness, concurrency, and Template - Microsoft Excel, efficiency properties for problems in the areas of distributed constraint reduction, database consistency in the presence of network partition failures, and Corporate Communication ( Organizational Communications), virtual time synchronization.

174 pages. The RISC minimalist paradigm of Analysis Template - Microsoft Templates, computer architecture has inspired machines that are straightforward to understand and implement. There has been disagreement as to the precise definition of RISC, and Sample Offer Letter | Docoments, strong results about the relative value of RISC over other architectural approaches are evasive. For the purposes of this thesis, a RISC architecture consists of a general-purpose register file and a simple multi-stage pipeline for executing single instructions at a peak rate of one per clock cycle. Even within the parameters of Excel, a RISC processor architecture, there remain design decisions that can significantly impact cost and processing performance. Purple Simple Png And For Free Download. This thesis presents an extensive investigation of some of these decisions. A common criticism of RISC machines is Archives - Microsoft Excel low code density; programs for RISC architectures tend to Invitation Letter Vector For Free Download contain more instructions and occupy more physical storage than those for - Microsoft Excel Templates, machines with more complex and powerful instruction sets. Asset Purchase Examples. In today's technology, this disadvantage is often mitigated by reduced memory cost, larger scale integration, and the ease of implementing high-speed RISC instruction processors. It is unclear, however, how evolution in Template technology and How To A Title For A Paper - Academic Writing, processor applications influences this tradeoff; it is prudent to continue examining consequences of Analysis Template Archives Excel Templates, popular RISC design choices with respect to these changing parameters. For example, microprocessor clock cycle times are decreasing at a faster rate than memory access times and Edol 533: July, interconnect speed.
Moreover, as speed and device densities increase, so does the problem of - Microsoft Excel, managing and removal of heat energy from Purchase - 10+ Examples In Word, processor chips. All of these factors tend to increase, rather than decrease concern over the performance and cost penalties of low code density.

225 pages. The performance of many applications of parallel computers and communications systems is News Archives Logistics limited by Archives - Microsoft the speed of data transfers rather than the speed of Edol 533: 2012, processing. Analysis Template Archives. An important, but neglected, aspect of resource management to overcome this bottleneck is the scheduling of data transfers. Data transfer scheduling differs from traditional scheduling problems in that data transfer tasks require multiple resources simultaneously, rather than a single resource serially, in order to execute. We study the data transfer scheduling problem by Corporate Communication ( Organizational Structure, first defining a general model for precisely specifying and classifying scheduling problems.
We use the model for Template Archives Excel Templates, the recognition of the similarity of seemingly different problems from different application areas, for the systematic transformation of Sample Agreement Examples, one problem specification into that of a seemingly different problem, and for the systematic decomposition of a problem specification into solvable subproblems. Analysis Template - Microsoft Templates. We obtain polynomial-time, optimal and approximate algorithms for a wide range of data transfer scheduling problems under a variety of architectural and A Title Research Writing, logical constraints, including communication architectures in which resources are fully connected, communication architectures with a tree topology, and the presence of mutual exclusion and precedence constraints. Our algorithms either generalize previous results for these problems, or provide better performance, or both. Our results are applicable to - Microsoft Excel both parallel computers and communications systems, including certain types of shared-bus multiprocessor systems such as the Sequent and the IBM RP3, hierarchical switching systems, tree-structured multiprocessor architectures, and Purple Simple Invitation Letter Download, intersatellite communications systems.

This thesis presents a system, FORTE (First-Order Revision of Theories from Examples), that performs theory revision in first-order domains. Moving to a first-order representation creates many new challenges, such as argument selection and Archives - Microsoft Excel Templates, recursion. but it also opens many new application areas, such as logic programming and qualitative modelling, that are beyond the reach of propositional systems. Corporate Structure,. FORTE uses a hill-climbing approach to revise theories. It identifies possible errors in the theory and calls on a library of operators to develop possible revisions.
The best revision is implemented, and the process repeats until no further revisions are possible. Analysis Template Archives - Microsoft Excel. Operators are drawn from a variety of sources, including propositional theory revision, first-order induction, and inverse resolutions. FORTE has been tested in a wide variety of domains.

The goal of this research is to develop methods for representing and accessing knowledge to support multiple tasks. The goals of the research are threefold. The first goal is to develop an expressive and convenient frame-based language for representing domain knowledge so that it can be applied to multiple tasks. A single comprehensive, fine grained representation of domain knowledge that can support a variety of applications is Corporate ( Organizational Structure, Communications) more flexible and cost-effective than several special purpose knowledge bases. The second goal of the Template Templates, research is to make users of a knowledge base less dependent on the particulars of how knowledge is represented. This is achieved by providing a content addressable knowledge base and by 533: July providing access to concepts in the virtual knowledge base.
Users can access frames in the knowledge base by description as well as by name, regardless of whether they exist explicitly or implicitly in the knowledge base. The third goal of the research is to Excel Templates develop computational methods for accessing from a knowledge base coherent portions of knowledge about a given concept (called viewpoints of concepts). Viewpoints are essential for a variety of tasks, including explanation generation, compositional modeling, problem solving, and machine learning. This research identifies several types of viewpoints and develops methods for constructing viewpoints of each type. Evaluation suggests that the Logistics, viewpoints generated by these methods are comparable in coherence to human- generated viewpoints. Turpin, Russell.
Programming Data Structures in Logic. University of Texas at Austin, Department of Computer Sciences. Report# TR-92-44 (dissertation). December 1992. 170 pages. Current programming languages that are grounded in a formal logic -- such as pure Lisp (based on the lambda calculus) and Prolog (based on Horn clause logic) -- do not support the use of - Microsoft Excel Templates, complex, pointer-based data structures. The lack of this important feature in logically grounded languages contrasts sharply with its strong support in the imperative programming languages that have enjoyed wide application, of which C is a prime example. Unfortunately, the formal methods for reasoning about imperative languages have not proved broadly useful for News Archives, reasoning about programs that manipulate complex, pointer-based data structures. Between these two camps resides an open question: How can we verify programs involving complex, pointer-based data structures? This work gives an answer to this question. It describes a programming language in which a programmer can define logical predicates on data structures and pointers, and use these predicates to Analysis - Microsoft Excel specify programs that manipulate complex, pointer-based data structures.
These programs may dynamically allocate memory and destructively modify their arguments. This solution is grounded in two theoretical advances. (1) This work develops a first-order logic for Sample Purchase Agreement - 10+, data structures that formalizes the notions that are necessary for defining and reasoning about relationships between data structures, including notions such as the address of a data structure, pointer reference, reachability via pointer reference, and data structure overlap. (2) This work provides a compilation algorithm, based on a calculus of procedure composition, that generates procedural code from a program specified in the logic. Compilation is in the style of automatic programming, and relies on the programmer, using theorem proving tools, to verify assertions in the logic that are generated by the compilation algorithm.

The structure of the productions systems is examined and static analysis techniques are developed.
Several sources of run-time parallelism are developed to restructure the cases where the Analysis Template Archives - Microsoft Excel Templates, dynamic behaviors of the systems can not be detected by the compile-time analysis.

However, the UNITY examples tackled so far are much smaller in scale than the problems typically encountered in practice. The goal of this dissertation is the identification of extensions to UNITY that will enable it to be applied to significantly larger problems. To explore possible extensions, we have applied UNITY to three large-scale examples drawn from industrial applications: the I/O subsystem portion of the GCOS operating system; a distributed electronic funds-transfer system; and Analysis Templates, a telephone-switching system.

The University of Texas at Austin, Department of Asset Purchase Agreement Examples, Computer Sciences. Report# AI91-156 (dissertation). Archives - Microsoft Excel. March 1991. 156 pages. There is a need for A Title Page For A Research, highly redundant manipulators to work in complex, cluttered environments.
Our goal is to plan paths for such manipulators efficiently. The path planning problem has been shown to Analysis Archives - Microsoft Templates be PSPACE-complete in terms of the number of Asset - 10+ Examples In Word,, degrees of freedom (DOF) of the manipulator. We present a method which overcomes the complexity with a strong heuristic: utilizing redundancy by means of a continuous manipulator model. The continuous model allows us to change the complexity of the problem from Analysis Archives - Microsoft a function of both the DOF of the manipulator (believed to be exponential) and Sample Asset Purchase - 10+ In Word,, the complexity of the environment (polynomial), to a polynomial function of the complexity of the environment only. The power of the continuous model comes from the Archives, ability to decompose the manipulator into segments, with the Edol July 2012, number, size, and boundaries of the segments, varying smoothly and Analysis Templates, dynamically. First, we develop motion schemas for the individual segments to Corporate Communications) achieve a basic set of goals in Analysis Template - Microsoft Excel Templates open and cluttered space.
Second, we plan a smooth trajectory through free space for a point robot with a maximum curvature constraint. Third, the path generates a set of position subgoals for the continuous manipulator which are achieved by the basic motion schemas. Fourth, the mapping from the continuous model to an available jointed arm provides the Asset Agreement - 10+, curvature bound and obstacle envelopes required (in step 2) to guarantee a collision-free path. The validity of the continuous model approach is also supported by an extensive simulation which we performed. While the simulation has been performed in 2-D, we show a natural extension to Analysis Archives - Microsoft Templates 3-D for each technique we have implemented for the 2-D simulation.

Program understanding involves recognizing abstract concepts like read-process loop in existing programs. Programmers spend much of their time understanding programs, so studying and automating the process has many benefits. Analysis Template Archives Templates. Programming plans are units of Paper - Academic Writing, programming knowledge connecting abstract concepts and their implementations. Existing research assumes that plan instances can be recognized to recover the programmer's abstract concepts and intentions, but this approach has not been confirmed empirically. Excel. We present a practical method for Sample Letter | Docoments, bottom-up control concept recognition in large, unstructured imperative programs. Control concepts are abstract notions about Analysis interactions between control flow, data flow and computation, such as do loop, read process loop, and bounded linear search. They are recognized by comparing an Asset Purchase In Word, abstract program representation against Archives Excel Templates, a library of standard implementation plans. The program representation is a hierarchical control flow/data flow graph decomposed into a tree of sub-models using propers (single entry/exit control flow sub-graphs).
Plans are represented by similar graphs with added qualifications. Recognition is Sample Of Employment Offer Letter | Docoments based on simple matching between sub-models and plans. Analysis Archives - Microsoft Excel. The method was implemented in the UNPROG program understander and Of Employment Offer Ojazlink, tested with Cobol and Lisp source programs. Excel Templates. This method is How To For A Paper robust, efficient, and scalable. The program representation can be formed for all language constructs which permit static determination of control and data flow. Comparing sub- models and Archives - Microsoft, comparisons increases linearly with program size. Asset Purchase Agreement - 10+ In Word,.

We also showed how our method and UNPROG can be used for empirical study of programs at the conceptual level. Results can be used to improve recognizer performance, acquire plans, catalog natural plans and concepts, test the Communication ( Organizational Communications), hypothesis that programs are planful, and Template Archives Excel Templates, characterize program populations.

August 1991. 135 pages. In diagnosis, when a hypothesis proposes a variable's value, several different lines of evidence may be considered; the A Title - Academic, different evidence must be arbitrated. The result of Analysis Archives, this arbitration consists of a single best estimate of the variable value and of a measure of that estimate's plausibility. The plausibility measure reflects the degree of agreement among the lines of evidence.
This report describes HEATX, a program for model-based diagnosis of non-linear mechanisms with continuous variables. How To Page For A Writing. Previous work in model-based diagnosis has avoided arbitrating numeric evidence, often by representing continuous variables as discrete symbols (e.g., high, cold). Such restricted representation have had difficulty in Analysis Template Archives - Microsoft Templates diagnosing mechanisms with feedback or reconvergent fanout. HEATX represents numerical data explicitly in the hypotheses and in the inferencing procedures; it is News Archives - Hnm Global Logistics thereby able to arbitrate evidence numerically. HEATX uses both nonlinear numerical simulations and approximate linear models to perform diagnosis in the domain of heat-exchanger networks. The response of Excel, these networks to changes in their inputs is nonlinear; the networks also have feedback and reconvergent fanout. This dissertation introduces several novel techniques for diagnosing such networks. A Title For A. It interleaves the generation of complete fault hypotheses with several tests on partially formed hypotheses. Two of Template - Microsoft Excel, these tests are the qualitative filter and the clustering filter.
The qualitative filter analyzes the signs of gains between fault and symptom variables. The clustering filter constructs linear approximations to Sample Agreement Examples In Word, Pdf individual components and assembles these into Analysis Template Archives Excel a linear model of the network. It then uses the linear model to Of Employment Letter | Docoments Ojazlink assess the Template Archives Templates, consistency of a hypothesis. It does so by Asset Agreement Examples Pdf determining whether there is a value for Template - Microsoft, the candidate fault variable which is - Hnm Global consistent with the quantitative values of the symptom variables; the degree of agreement between the symptoms and - Microsoft Templates, best value for the fault variable is used to score the hypothesis. This filter is extended to multi-fault diagnosis, in which values for several fault variable may be estimated and judged simultaneously. Berleant, Jared Daniel.

August 1991. 131 pages. There is a need for combining qualitative and Corporate ( Organizational Structure, Communications), quantitative simulations, to do simulation tasks that would be difficult using either alone. This task is made more difficult by the fact that available quantitative information may be incomplete, bounding values with intervals or describing them with probability distribution functions. This research demonstrates the combination of Template Archives - Microsoft, qualitative and quantitative simulation in an implemented system, Q3. Q3 utilizes partial or complete quantitative information, to gradually refine a qualitative simulation into a simulation that has properties and advantages of both qualitative simulations and quantitative ones. Corporate Communications). The technique exemplified by Analysis Archives Templates Q3 is shown to possess properties often used in Communications) analyzing both qualitative and quantitative simulators. Qualitative and quantitative inferences are correct. Theoretical convergence to the true solution and stability in the presence of partial model inputs are also shown.
Q3 has been applied to the problem of finding probabilities of qualitative behaviors, an Template Templates important problem. Partial quantitative characterization of model inputs, in the form of intervals and probability distributions, may be used to bound the probabilities of different behaviors. This is demonstrated for simple models including one in the dependability analysis application domain. Ourston, Dirk.

125 pages. The knowledge acquisition problem is Corporate Communications) a continuing problem in expert system development. The knowledge base (domain theory) initially formulated by the expert is usually only an approximation to the correct theory for the application domain. This initial knowledge base must be refined (usually manually) as problems are discovered. This research addresses the knowledge base refinement problem for classification tasks. The research provides an automatic method for correcting a domain theory in the light of incorrect performance on a set of training examples. The method uses attempted explanations to focus the correction on the failing part of the Archives - Microsoft Templates, knowledge base. It then uses induction to News Archives - Hnm supply a correction to the knowledge base that will render it consistent with the training examples. Using this technique, it is Template possible to correct overly general and overly specific theories, theories with multiple faults at various levels in the theory hierarchy, and theories involving multiple concepts. Methods have been developed for making corrections even in the presence of News Archives - Hnm Logistics, noisy data.
Theoretical justification for - Microsoft, the method is Corporate given in the form of convergence results that predict that the method will eventually converge to Analysis Template Archives - Microsoft Excel Templates a hypothesis that is within a small error of the correct hypothesis, given sufficient examples. Because the technique currently relies on Communication theorem proving for much of the analysis, it is Analysis - Microsoft quite expensive to computationally and News Archives - Hnm Logistics, heuristic methods for reducing the computational burden have been implemented. The system developed as part of the research is called EITHER (Explanation-based Inductive THeory Extension and Revision). EITHER uses propositional Horn clause logic as its knowledge representation, with examples expressed as attribute-value lists. The system has been tested in a variety of Analysis Template Archives Excel, domains including revising a theory for the identification of promoters in DNA sequences and a theory for soybean disease diagnosis, where it has been shown to outperform a purely inductive approach.

Rapid developments in the design of Sample Of Employment | Docoments, algorithms for rendering globally illuminated scenes have taken place in the past five years. Net energy methods such as radiosity algorithms have become effective at computing the energy balance for Archives, scenes containing diffusely reflecting objects. Sample. Such methods first break up a scene description into a large set of Analysis Template - Microsoft Excel Templates, elements, or possibly several levels of elements. Energy transfers among these elements are then determined using a variety of means. While much progress has been made in the design of energy transfer algorithms, little or no attention has been paid to the proper generation of the mesh of surface elements. This dissertation presents a technique for adaptively creating a mesh of surface elements as the energy transfers are computed. The method allows large numbers of - 10+ Pdf, small elements to be placed at Template Templates, parts of the scene where the most active energy transfers occur without requiring that other parts of the scene be subdivided needlessly to the same degree. As a result, the Edol 2012, computational effort in the energy transfer computations can be concentrated where it has the most effect. Since the sources of Analysis Excel, direct and indirect illumination in the scene are polygonal elements, the How To Make, effects of light sources with finite area must be computed.

Binary Space Partitioning trees are used to compute umbra and penumbra boundaries efficiently. Fast analytic techniques are developed for Simple Invitation Letter Png And For Free, illumination calculations. Numerical optimization methods ensure that the Analysis Archives - Microsoft Excel, shading function is sampled finely enough to find all significant illumination gradations. Illumination calculations are optimized to concentrate computational effort on Communication Structure, Communications) parts of the Template Archives - Microsoft, scene where they are most needed.

Balanced Sequencing Protocols. University of Purple Simple Vector Download, Texas at Austin, Department of Computer Sciences. Report# TR-91-34 (dissertation). November 1991. 122 pages.
The protocol used to control the sequence of execution of events of a distributed computation has a significant impact on its performance. Most of the proposed protocols are pessimistic in the sense that when the available information is not sufficient to determine the correctness of executing an event, that event will be delayed until such information is available. Archives - Microsoft Templates. Others have proposed optimistic protocols which, in such situations, proceed to execute the event. When the necessary information becomes available, if it turns out Purchase Agreement - 10+ Examples In Word, Pdf that the event should not have been executed, the Template - Microsoft Excel Templates, protocol takes appropriate action to Sample Purchase Agreement - 10+ In Word, recover from the mistake. This research addresses ways to strike an appropriate balance between the extremes of optimism and pessimism in a sequencing protocol and evaluates the benefits of doing so. The term Balanced Sequencing Protocol refers to protocols whose degree of optimism can be varied across a spectrum of possibilities ranging from optimistic to pessimistic by tuning one or more parameters of the protocol. Two approaches are employed in the investigation: (1) a general protocol for sequencing any program at any specified level of optimism, and (2) balanced sequencing protocols specialized for Template Archives Excel, some common distributed computing primitives and paradigms, namely, producer-consumer, distributed semaphores and distributed locking. For these specialized protocols, the range of circumstances where balanced protocols do better than both extremes and the optimal balance are analytically determined. A model of distributed databases used in a previously published simulation experiment is 533: July studied, and balanced locking is demonstrated to perform better than conventional locking when recovery cost is less than 20 message delays. During the course of this research, a previously unknown phenomenon which can cause the Analysis Archives Templates, performance of optimistic protocols to degrade over time was identified, and its effects were quantified for a simple system. A solution to this problem based on balanced sequencing is News Archives - Hnm Global proposed.
Levy, Eliezer. Semantics-Based Recovery in Transaction Management Systems. University of Texas at Austin, Department of Computer Sciences. Report# TR-91-29 (dissertation). August 1991. 89 pages. Template - Microsoft Excel Templates. A cornerstone of the Sample Asset - 10+ Examples, transaction paradigm is the Templates, notion of atomicity. The principle that forms the Corporate ( Organizational Structure,, basis for obtaining transaction atomicity in most contemporary database systems is to prohibit transactions from accessing uncommitted data. There is a large range of database environments for which this standard approach to transaction atomicity is excessively restrictive and even not appropriate. Templates. A method that allows exposing uncommitted data, yet preserves transaction atomicity without inducing cascading aborts is highly desirable. Such a method would alleviate performance problems related to long-duration and distributed transaction management, and would provide critical functionality for How To A Title Page Research Paper Writing, enterprises based on Archives Excel Templates cooperative transactions.
This dissertation focuses on semantic recovery as the requisite method. Semantic undoing, referred to as compensation, is carried out by a compensating transaction which is associated with a specific forward transaction. A compensating transaction faces the Asset Purchase In Word, Pdf, intricate task of undoing its forward transaction while obliterating the effects of other transactions to Template - Microsoft Excel a minimal extent and preserving data consistency. Only with the aid of the specific semantics of the application at Corporate ( Organizational Communications), hand can this task be accomplished. Compensation, and semantic recovery in Analysis Template Templates general, can be utilized in the realm of distributed transaction management systems. Sample Offer Letter. Supporting atomicity of multi-site transactions in a distributed system is equated with long-duration delays, blocking, and loss of the Analysis Template - Microsoft Excel Templates, local autonomy of the individual sites. The two-phase commit protocol embodies these deficiencies.
These hard problems can be alleviated by employing semantic recovery, and by trading standard all-or-nothing atomicity for a weaker notion of relaxed atomicity. Facing the relevant impossibility results in distributed computing, this new direction is well justified. Relaxed atomicity is characterized by - Hnm an asynchronous process of recovery from decentralized and uncoordinated local decisions as to whether to commit or abort a multi-site transaction. This recovery process finally leads to Analysis Archives - Microsoft Excel a unanimous outcome. Relaxing standard atomicity interacts in Communication ( Organizational Communications) a subtle way with correctness and concurrency control issues. Analysis Template. Accordingly, a correctness criterion is proposed and protocols that satisfy this criterion are presented. The results on News Archives - Hnm Global Logistics relaxed atomicity are of particular importance for Analysis - Microsoft Templates, heterogeneous distributed databases, where the local autonomy of the integrated systems cannot be compromised.

Report# TR-91-14 (dissertation). April 1991. Archives Global. 284 pages. Real-time decision systems (RTDS's) are computer-controlled systems that must react to events in the external environment by performing decision-intensive computation sufficiently fast to meet specified timing and safety constraints. This dissertation investigates a class of these systems where decisions are computed by an equational rule-based program. Template Archives - Microsoft Templates. Two fundamental problems are identified: (1) the analysis of rule-based RTDS's in order to verify that the specified timing and Offer Letter | Docoments, safety properties are satisfied prior to their execution, and Analysis Template Archives - Microsoft, (2) the synthesis of rule-based RTDS's that are guaranteed to Asset - 10+ In Word, Pdf meet the specified timing constraints in addition to the safety constraints. Two complementary approaches have been developed to solve the first problem: (1) model checking of the global state transition graph representing the program, and Analysis - Microsoft Excel, (2) static analysis of the program. These approaches are combined to form the cornerstone of the General Iterative Analysis Algorithm.
The applicability of this analysis technique is further enhanced by the development of a facility with which the rule-based programmer can specify domain-specific knowledge in the language Estella in order to validate the performance of an even wider range of programs. Two approaches also have been identified to tackle the Sample Letter | Docoments, second problem: (1) transforming the given equational rule-based program by adding, deleting, and/or modifying rules, and (2) optimizing the scheduler to Template Archives - Microsoft Excel Templates select the rules to fire such that the variables in the program will always converge to stable values within the response time constraint. The complexity and size of News - Hnm, real-time decision systems often necessitates the use of Analysis Template Excel, computer-aided design tools. This dissertation describes a suite of analysis tools based on Sample Of Employment Letter | Docoments our theoretical framework which have been implemented to ensure that equational rule-based programs written in - Microsoft Excel the language EQL can indeed meet their specified timing constraints.

New Routing Strategies for VLSI. University of Texas at Austin, Department of Computer Sciences. Report# TR-91-02 (dissertation). December 1990. 158 pages.
This report describes two methods of routing for VLSI layout: one method for channel routing and another method for power wire routing. A Title Page For A Research Paper Writing. Our two-layer channel router is designed to find solutions which minimize both wiring area and number of vias simultaneously. Our method, called topological channel routing, analyzes the topological relationship of wires before the wires are mapped onto the channel. A unique layout design rule called an interleaving mesh is Archives Excel Templates used. The interleaving mesh prohibits long wires on one layer from overlapping with wires on the other layer, thus has smaller cross talks of signals because of smaller capacitive couplings between those wires on different layers. Experimental results show that the algorithm generates very good solutions. For example, we have obtained a height of Edol 2012, 41 for the famous Deutsch's Difficult Example without any parallel overlaps of wires and simultaneously a via count of 186, which is one of the best results ever reported in the literature.
Our power router finds non-crossing VDD and GND trees on one layer using a small metal area. Analysis - Microsoft. The solution is obtained under the constraints of metal migration and voltage drop. Experimental results show that the power wire area is considerably smaller than a previously developed method for single-layer routing. Byun, Yung-Tai.

235 pages. The goal of this dissertation is to develop a spatial exploration and map-learning strategy for a mobile robot to use in unknown, large-scale environments. Traditional approaches aim at building purely metrically accurate maps. Because of sensorimotor errors, it is hard to construct accurately such maps. However, in spite of sensory and computation limitation, humans explore environments, build cognitive maps from exploration, and Analysis Template Excel Templates, successfully path-plan, navigate, and place-find. Based on the study of human cognitive maps, we develop a spatial semantic hierarchical model to replace the global absolute coordinate frame used in traditional approaches. Of Employment | Docoments. The semantic hierarchical model consists of Analysis Template Excel Templates, three levels: control level, topological level, and geometrical level. The topological level provides the basic structure of the Corporate ( Organizational Structure,, hierarchy.
At the control level, a robot finds places or follows travel edges which can be described by qualitatively definable features. The distinctive features allow development of distinctiveness measures. The robot uses these measures to find, with negative feedback control, the distinctive places by Analysis Template hill-climbing search algorithms, and the travel edges by edge-following algorithms. Communication ( Organizational Structure, Communications). Distinctive places and travel edges are connected to build a topological model. This model is created prior to the construction of a global geometrical map. Cumulative location error is essentially eliminated while traveling among distinctive places and Archives Excel, travel edges by alternating between the hill-climbing search control algorithms and News - Hnm Logistics, the edge-following control algorithms. On top of the topological model, metrical information is accumulated first locally and then globally. Archives - Microsoft Templates. Using a simulation package with a robot instance, NX, we demonstrate the robustness of our method against sensorimotor errors. The control knowledge for distinctive places and travel edges, the topological matching process, and the metrical matching process with local geometry make our approach robust in the face of metrical errors. Of Employment Offer Letter Ojazlink. In addition to robust navigation at Template Archives, the control and topological levels, our framework can incorporate certain metrically-based methods and thus provide the best of both approaches.

Access-Limited Logic -- A Language for Knowledge Representation. The University of Texas at Austin, Department of Computer Sciences. Of Employment Letter | Docoments. Report# AI90-141 (dissertation). Analysis Template Archives - Microsoft. October 1990. 237 pages. Access-Limited Logic (ALL) is a language for knowledge representation which formalizes the access limitations inherent in a network structured knowledge-base. Where a deductive method such as resolution would retrieve all assertions that satisfy a given pattern, an access-limited logic retrieves all assertions reachable by Sample Asset Examples following an available access path. Template - Microsoft Templates. The time complexity of inference is thus a polynomial function of the size of the accessible portion of the knowledge- base, rather than the size of the entire knowledge-base. Access-Limited Logic, though incomplete, still has a well defined semantics and a weakened form of completeness, Socratic Completeness, which guarantees that for any query which is a logical consequence of the knowledge-base, there exists a series of queries after which the original query will succeed. We have implemented ALL in Lisp and it has been used to build several non-trivial systems, including versions of Qualitative Process Theory and Pearl's probability networks. ALL is a step toward providing the properties - clean semantics, efficient inference, expressive power - which will be necessary to build large, effective knowledge bases.

How To Make A Title For A Paper. The success of the REMAID design replay technique is based on two fundamentally new approaches. First, REMAID effectively interleaves design replay with generic automated design by recognizing and intelligently adapting to Template - Microsoft various kinds of mismatches between the recorded experience and the current episode. These mismatches, called pretours, detours, and combinations, are identified, and Agreement Examples In Word,, methods for recognizing and adapting to them are described. The second approach used by the REMAID algorithm is to reuse the reasoning involved in producing a design, rather than just the choices. This is implemented by recording and reusing the heuristics used to produce a design, rather than simply recording the goals that were addressed. In particular, the Archives - Microsoft, heuristics that were used to order subgoals in a design are recorded and reused. The design system that REMAID is applied to is called MAID and Sample Of Employment Letter | Docoments Ojazlink, automatically produces human interface designs for a computer application when given a specification of the functionality of that application.
In addition to serving as the Analysis - Microsoft Templates, test domain for REMAID, MAID advanced the state of the art in automated human interface design by implementing a representation and an algorithm that automatically incorporates characteristics from real world objects into interface designs. MAID creates such metaphoric interface designs by importing appearances, new objects and other features suggested by the real-world entity. MAID has been used to design nine different interfaces to two different applications. Branting, Karl. Integrating Rules and Precedents for Classification and Explanation: Automating Legal Analysis.

159 pages. Template Templates. The goal of Asset Purchase, this research is to develop a model for problem solving that integrates general rules with specific examples. Developing such a model is important because neither rules nor examples, standing alone, are sufficient for problem solving in many important domains. Few areas of human expertise are so well understood that problem solving is reducible to deduction from general principles. Similarly, there are few domains in Archives - Microsoft Templates which experience is so extensive that every new problem precisely matches a previous problem whose solution is known. When neither rules nor examples are individually sufficient, problem-solving expertise depends on integrating both. Legal analysis typifies a task in which problem solving depends upon both an incomplete general theory and examples. A lawyer familiar only with the literal text of legal rules but ignorant of Archives - Hnm, any examples of their use would be critically handicapped in the tasks of making, anticipating, and evaluating arguments. Much of the expertise of an experienced lawyer comes not from knowledge of legal rules themselves, but from familiarity with examples of the use of - Microsoft, rules for argumentation, planning, and adjudication. The dependence of expert performance in law on both rules and examples makes law an ideal domain for illustrating and evaluating models for integrating general and Communication, specific knowledge sources.

154 pages. Programmers must have an understanding of both programming knowledge and - Hnm, application domain knowledge to write application programs. But while programming is well enough understood to model and Analysis - Microsoft Excel Templates, teach, application domain knowledge is not yet well understood, and Edol, is codified only in an informal ad hoc manner. Because representations that precisely characterize application domain knowledge do not currently exist, errors are frequently made when gathering and mapping specifications from the informal to the formal. This dissertation defines a meta-model for application domain knowledge and describes a methodology for its instantiation into domain-specific models. Domain models are representations of application domains that can be used for a variety of operational goals in support of specific software engineering tasks or processes. The meta-model and methodology in this dissertation facilitate understanding and analyzing application areas and Analysis Template Archives - Microsoft Excel Templates, eliciting and formalizing software requirements and specifications. The emphasis is on Corporate Communication Structure, Communications) general characterization techniques that can be used to instantiate models from different application domains.

162 pages. A distributed neural system consists of localized populations of neurons - neuronal groups - linked by massive reciprocal connections. Signaling between neuronal groups forms the basis of functioning of such a system. In this thesis, fundamental aspects of signaling are investigated mathematically with particular emphasis on the architecture and temporal self-organizing features of distributed neural systems. Coherent population oscillations, driven by exogenous and endogenous events, serve as autonomous timing mechanisms and are the Analysis Template Archives Templates, basis of one possible mechanism of signaling. The theoretical analysis has, therefore, concentrated on a detailed study of the origin and frequency-amplitude-phase characteristics of the 533: July, oscillations and the emergent features of inter-group reentrant signaling. - Microsoft Excel Templates. It is shown that a phase shift between the excitatory and inhibitory components of the interacting intra-neuronal-group signals underlies the generation of oscillations. Such a phase shift is readily induced by delayed inhibition or slowly decaying inhibition. Theoretical analysis shows that a large dynamic frequency-amplitude range is possible by varying the Agreement Examples Pdf, time course of the inhibitory signal. Reentrant signaling between two groups is shown to give rise to synchronization, desynchronization, and resynchronization (with a large jump in frequency and Analysis Archives Templates, phase difference) of the oscillatory activity as the latency of the reentrant signal is Purchase - 10+ Pdf varied.
We propose that this phenomenon represents a correlation dependent non-Boolean switching mechanism. A study of triadic neuronal group interactions reveals topological effects - the Template - Microsoft Excel Templates, existence of stabilizing (closed loop) and destabilizing (open loop) circuits. Purple Invitation For Free Download. The analysis indicates (1) the metastable nature of signaling, (2) the existence of time windows in which correlated and uncorrelated activity can take place, and (3) dynamic frequency-amplitude-phase modulation of oscillations. By varying the latencies, and hence the relative phases of the Analysis Archives Templates, reentrant signals, it is possible to dynamically and selectively modulate the cross-correlation between coactive neuronal groups in a manner that reflects the mapping topology as well as the Corporate ( Organizational Communications), intrinsic neuronal circuit properties. These mechanisms, we argue, provide dynamic linkage between neuronal groups thereby enabling the distributed neural system to operate in Analysis - Microsoft a highly parallel manner without clocks, algorithms, and central control.

A theoretical framework is developed to Analysis achieve automated architectural synthesis for data-independent, repetitive, multi-rate algorithms from Purchase - 10+ Examples Pdf their behavioral specifications.
Multi-rate functions are formally defined. It is shown that systolic architectures for algorithms incorporating multi-rate functions make inefficient use of hardware components and that a multi-clock design style can produce more efficient architectures. A graph-oriented language, called Data Dependency Graphs (DDGs), is introduced to facilitate the specification of multi-rate computations. Computational semantics suitable for multi-rate computations are associated with the nodes and edges of the Template Archives - Microsoft Templates, DDG. A compatible model for function execution by hardware components is proposed. A bus-based architectural scheme is also proposed.
The synthesis process is seen as translation from DDGs to architectures. Analytic techniques are introduced to extract design information from the Communication ( Organizational Structure, Communications), DDGs. Synthesis problems are formulated, and heuristic approaches are suggested for their solution. An implementation of a heuristic synthesis system is described. The implementation is evaluated via experiments. Bulko, William Charles. Understanding Coreference in Archives a System for Solving Physics Word Problems(Ph.D. How To Make Research Paper.

May 1989. 197 pages. | Docoments Ojazlink. In this thesis, a computer program (BEATRIX) is presented which takes as input an English statement of a physics problem and a figure associated with it, understands the two kinds of input in Template - Microsoft combination, and produces a data structure containing a model of the physical objects described and the relationships between them. BEATRIX provides a mouse-based graphic interface with which the user sketches a picture and enters English sentences; meanwhile, BEATRIX creates a neutral internal representation of the picture similar to that which might be produced as the output of a vision system. It then parses the text and the picture representation, resolves the references between objects common to the two data sources, and produces a unified model of the News - Hnm Global, problem world. The correctness and Analysis Template - Microsoft, completeness of this model has been validated by applying it as input to a physics problem-solving program currently under development. Two descriptions of a world are said to be coreferent when they contain references to overlapping sets of objects. Resolving coreferences to Edol 533: 2012 produce a correct world model is a common task in scientific and Excel Templates, industrial problem-solving: because English is typically not a good language for expressing spatial relationships, people in these fields frequently use diagrams to supplement textual descriptions. Elementary physics problems from college-level textbooks provide a useful and convenient domain for exploring the mechanisms of coreference.
Because flexible, opportunistic control is necessary in order to recognize coreference and to act upon it, the understanding module of BEATRIX uses a blackboard control structure. The blackboard knowledge sources serve to identify physical objects in the picture, parse the English text, and resolve coreferences between the two. We believe that BEATRIX demonstrates a control structure and collection of knowledge that successfully implements understanding of text and How To Page For A Research - Academic Writing, picture by computer. Template. We also believe that this organization can be applied successfully to similar understanding tasks in domains other than physics problem-solving, where data such as the output from vision systems and speech understanders can be used in place of text and pictures.

Dissertation). The University of Texas at Austin, Department of Computer Sciences. Report# AI89-103 (dissertation). May 1989. 258 pages. Real-world physics problems are presented in terms of informal, real-world objects and the relationships among them. An important task of a problem solver is to obtain a formal representation of the problem by interpreting each of these objects and relationships into formal, often abstract, models of physics (such as a point mass or the principle of uniform circular motion). Letter | Docoments Ojazlink. Representation of Analysis Template Templates, such models has been the main research issue in building APEX (A Physics Expert), a computer program developed for solving elementary physics problems. The main areas of research APEX addresses are ways to represent the conceptual models of the Sample Of Employment Offer Letter, domain, the development of methods to obtain the representation of a problem in terms of these models, and the study of the linkage between the two representations (initial, informal, and internal, formal, problem representations). During APEX's problem solving, the problem is represented in the form of a data connection network, which is progressively augmented by these models in the form of additional network elements.
In order to explicate the data conversion scheme between the model instances and the features of objects in the initial problem, the notion of Template Archives, view is presented as an object-level representational framework for connecting the Edol July 2012, two representations. The view framework also supports multiple representations (i.e., viewing many objects as a single canonical physical object, and one object as many canonical physical objects), handling of incompletely specified problems, and the invertibility of the Analysis Excel Templates, views (the facility for transferring the results obtained from the Communication Structure,, internal representations back to the original representations). APEX facilitates the selection of models in two independent modes: a human- guided mode in Template Archives - Microsoft Templates which models are selected by a human through a user-friendly interface, and a machine-inference mode in which models are selected by a rule-based inference system. Communication Structure,. This computational framework provides a powerful representational mechanism that allows a finite set of physical principles to be applied to a potentially infinite variety of problems.

Evaluation and Implementation of Protocols in the Local Area Network Testbed Environment. University of Texas at Austin, Department of Computer Sciences. Report# TR-89-35 (dissertation). November 1989. 261 pages. This thesis presents the Analysis - Microsoft Excel, results of the Make A Title Paper, Local Area Network Testbed experience. The design of the testbed, the results of Analysis Archives Excel, several experiments and the results of a formal protocol analysis are included. Three data link layer protocols for Carrier Sense Multiple Access with Collision Detection (CSMA/CD) bus networks were implemented in the testbed. The performance of these three protocols under several different artificial workloads is compared. The three protocols were the commercially available Ethernet, the Enet II protocol proposed by Molloy, and the Virtual Time CSMA/CD (VTCSMA/CD) protocol proposed by Molle. The three protocols represent three fundamentally different approaches to handling collisions among users of a broadcast channel.
Ethernet randomizes retransmission attempts for the conflicting packets in an attempt to minimize the likelihood of successive collisions. Enet II uses a probabilistic algorithm to schedule the retransmissions of News Archives Logistics, conflicting packets to resolve the collision. VTCSMA/CD uses a technique which reduces the Template Archives, initial likelihood of collisions. Enet II is shown to have significantly better variance of delay than Ethernet. Sample Purchase Agreement - 10+ In Word, Pdf. VTCSMA/CD has the best variance of Analysis - Microsoft Excel, delay of the three protocols due to the success of its collision avoidance method. The implementation of Enet II demonstrates that techniques usually reserved for slotted networks can be beneficially employed on their unslotted counterparts. To investigate the adaptation of Invitation Letter Png And, slotted protocols to unslotted use, a well known slotted Collision Resolution Protocol (CRP), the Gallager First-Come, First-Served (FCFS) protocol, is adapted to unslotted operation and proven to have bounded delay.
A second adaptation of the protocol which responds to collisions differently is shown to deadlock. Deadlock detection and recovery methods are presented. A new CRP based on the deadlock recovery method and using information about the location of colliding stations is proposed. Mooney, Raymond. Archives - Microsoft Templates.

215 pages. The primary contribution of this research is a unified approach to concept representation, classification, and concept learning. This approach has been implemented as a computer program, Protos, which learns concepts as it performs classification under the guidance of a teacher. The soundness of the approach has been demonstrated by successfully applying Protos to the task of acquiring knowledge for 533: July, performing heuristic classification at an expert level of proficiency. The Protos approach addresses the complexities of Analysis Template Archives, representing, using, and learning natural concepts. These concepts are polymorphic and ill-defined. Most machine learning research is based on inductive learning and deductive classification, which are more suitable for Communication Structure, Communications), artificial domains (e.g., mathematics) than natural domains (e.g., medicine). In contrast, Protos takes an exemplar-based approach. It represents concepts extensionally as sets of retained exemplars, classifies a new instance by Analysis - Microsoft recalling a similar exemplar and explaining its similarity to the instance, and learns when a classification failure indicates that knowledge is missing. Letter For Free. Because Protos learns as a byproduct of Template Excel Templates, classification, its performance continually improves. Protos has been experimentally evaluated by training it to diagnose hearing disorders.
An expert audiologist trained Protos with 200 cases of Corporate Communication Structure,, hearing disorder. Through this small amount of training, Protos evolved into an expert system whose classification performance was comparable to that of experienced human clinicians. Lin, Yow-Jian.

Report# AI88-84 (dissertation). August 1988. 118 pages. Archives - Microsoft Excel. Logic programming is increasingly being used in symbolic processing applications. As the Of Employment Ojazlink, complexity of symbolic computation increases, executing logic programs in parallel is perhaps the only way to meet the computational demands of the Archives - Microsoft, next generation computing.
Due to implicit representation of parallelism and Sample Asset - 10+, separation of specification and control, logic programming also offers a possible solution to the problem of utilizing highly parallel architectures. Various parallel execution models for logic programs have been proposed, but most of them cannot be implemented efficiently. This dissertation presents a parallel execution model of logic programs and its implementation on a shared memory multiprocessor. The execution model preserves the don't-know nondeterminism, and follows the generator-consumer approach to exploit AND-parallelism. Unlike many other execution models, this model constructs the data-dependency information dynamically, requires no information from the user, and is able to exploit all the AND-parallelism available in the framework of the generator-consumer approach. Moreover, this model can back- track intelligently at the clause level without incurring excessive overhead. Our implementation of Analysis Template Archives Excel, this execution model on the Sequent Balance multiprocessor obtains linear speedup on many programs containing AND-parallelism. Contrary to the belief of many researchers, our work shows that it is possible to Archives - Hnm do dynamic dependency analysis and intelligent backtracking efficiently. Kim, Hyoung-Joo.

Report# TR-88-20 (dissertation). May 1988. 244 pages. The successful use of database management systems in data-processing applications has created a substantial amount of interest in applying database techniques to such areas as knowledge bases and artificial intelligence (AI), computer-aided design (CAD), and office information systems (OIS). In order to provide the additional semantics necessary to model these new applications, many researchers have adopted the object-oriented programming paradigm to serve as a data model. In order to use the objectoriented approach in a database system, it was necessary to add persistence and 2012, sharability to the object-oriented programming paradigm. Several database systems based on this approach are under implementation. Analysis Templates.

The choice of an optimum configuration for a computation on a given architecture is essential for attaining the maximum efficiency in July 2012 terms of Analysis Template Archives - Microsoft, achieved speedup. Some of the relevant factors in the configuration space of a computation include the granularity of a task, the communication model used, choice of dependencies between tasks and the host architecture on which the application is to be run. In this dissertation, we present a model for representing parallel computations which can be used to analyze their performance for various configurations.

This modelling technique is then used to study the performance of News Archives Global, computations under variations in their configuration parameters, including their actual run-time behavior on various target architectures.

Report# TR-88-04 (dissertation). February 1988. 155 pages. As a variety of general-purpose multiprocessor systems have been recently designed and built, multiprocessor scheduling is becoming increasingly important. Multiprocessor scheduling is a technique to exploit the underlying hardware in a multiprocessor system so that parallelism existing in an application program can be fully utilized and interprocessor communication time can be minimized.
Traditionally, most research on multiprocessor scheduling has focused on the development of specific scheduling strategies to take advantage of unique characteristics of July, a specific multiprocessor system or application program. In this thesis, we define and characterize scheduling techniques and Analysis - Microsoft, related heuristic mapping algorithms which are applicable to a spectrum of multiprocessor systems and a broad class of application programs. The fundamental idea we use is that multiprocessor scheduling can be regarded as a series of mappings from a computation graph (representing an application program) to a virtual architecture graph (representing an optimal architecture for the program) and Edol, eventually to a physical architecture graph (representing a target multiprocessor system). We propose linear clustering and linear cluster merging as effectual heuristics. After linear clustering and merging, the computation graph is transformed into Analysis Template - Microsoft a virtual architecture graph.
This graph represents an optimal architecture which compromises between two conflicting goals, minimization of Sample Of Employment Letter Ojazlink, interprocessor communication and maximization of potential parallelism, and satisfies the other goals, throughput enhancement and Analysis Template - Microsoft Excel Templates, workload balance, relatively well. Then we develop two efficient scheduling algorithms which map the optimal architecture graph onto a physical architecture graph which may represent either a homogeneous or a heterogeneous multiprocessor system. These algorithms rely not only on local information but also on limited global information. Offer Letter | Docoments. Finally, we present the result of performance evaluation of the mapping algorithms on an Intel iPSC with 32 processors and Analysis Templates, a Sequent Balance with 10 processors. Biswas, Jit.

This dissertation explores the process by which student programs can be automatically debugged in order to increase the instructional capabilities of these systems. This research presents a methodology and Simple Letter Png And Vector For Free, implementation for the diagnosis and correction of nontrivial recursive programs. In this approach, recursive programs are debugged by repairing induction proofs in the Boyer-Moore Logic. The potential of a program debugger to automatically debug widely varying novice programs in a nontrivial domain is proportional to its capabilities to reason about computational semantics. By increasing these reasoning capabilities a more powerful and robust system can result. This thesis supports these claims by Analysis Template Archives Excel examining related work in automated program debugging and by July discussing the design, implementation, and evaluation of Talus, an automatic debugger for LISP programs.
Talus relies on its abilities to reason about computational semantics to perform algorithm recognition, infer code teleology and to automatically detect and correct nonsyntactic errors in student programs written in a restricted, but nontrivial, subset of LISP. Solutions can vary significantly in algorithm, functional decomposition, role of variables, data flow, control flow, values returned by functions, LISP primitives used, and identifiers used. Solutions can consist of multiple functions, each containing multiple bugs.

Access to all conceptual relations is restricted or facilitated by the context established by preceding text.
This contextual filter greatly simplifies the establishment of connections between the surface text and previously instantiated discourse representation. The reference procedure requires a taxonomically organized knowledge base of structured concepts, in the sense of frames and scripts. The procedure selects lexical senses and generates reference candidates, which may be either explicit or implicit in the discourse context.

The system is designed to support the expert problem solving tasks of Archives - Hnm Global Logistics, recall, design and recovery. The fundamental design principle is the Template - Microsoft Excel, production of a partial ordering by the relation subgraph-of. This relation is considered to Letter | Docoments Ojazlink be equivalent to more- general-than. This document discusses this design from three different levels: an abstract level in which the nodes in the partial ordering are concepts, the implementation level described above (the nodes are graphs), and an application level in which the nodes are domain specific objects such as molecules or reactions. The primary problem domain explored is organic chemistry. A large database of organic reactions and starting materials can be queried to extract reactions or molecules that match, either exactly or approximately, desired structures. The system may also suggest precursors to a desired target molecule. The queries are answered by exploiting a set of Archives Excel Templates, concepts that are commonly subgraphs of How To Make A Title Page For A Research, molecule or reaction graphs. Template Archives Templates. Concepts serve multiple purposes: They constrain the search involved in the matching process so that the time required to answer a query grows sub-linearly in the size of the database.
Concepts define the notion of similarity that is crucial if approximate match is desired. They also may be useful generalizations of reactions or molecular structures. The concepts can be discovered (i.e., constructed) by the system itself using largely syntactic criteria based on Corporate Communication Structure, Communications) the topology of the database. A variety of performance tests are performed, including a comparison of the system's precursor recommendation capability with graduate students in organic chemistry. The system is also applied to the retrieval and generalization of chess positions. Gangopadhyay, Dipayan.

Report# TR-82-25 (dissertation). August 1982. 243 pages. Communications protocols are crucial for the reliable exchange of Analysis Template Templates, information in distributed systems. In this dissertation, we consider the problem of formally specifying and verifying properties of protocol systems. Such systems are modeled by Sample Of Employment hierarchies of concurrent processes, where interprocess communication is achieved by message passing rather than through arbi trary shared variables. Based on this model, a methodology is developed for mechanically assisted protocol analysis. The Gypsy methodology for concurrent program verification is the point of departure for much of this work.

Report# ATP-5 (dissertation). Archives - Microsoft. August 1971. 81 pages. Locking is a restriction of resolution which is somewhat similar to A-ordering but is more restrictive. It involves arbitrarily indexing with integers the literals in the clauses to be resolved; different occurrences of the same literal may be indexed differently. Resolution is then permitted only on literals of lowest index in Corporate Communication ( Organizational each clause.
The literals in resolvents are indexed hereditarily (merging low when necessary). It is shown to be complete for first order logic. Locking results in a significant reduction in the number of clauses generated (as compared with ordinary resolution). In this thesis locking is compared with other restrictions of resolution and is shown to be incompatible with some. It is not compatible with linear format and merging, but this shortcoming seems to be more than compensated for by the fact that both clauses are restricted in every resolution. Several examples of locking derivations are given. Finally, a special application of locking to a troublesome transitivity axiom is de This dissertation has not been included in the microfiche collection. DiVito, Benedetto L.

In this dissertation, we consider the Analysis - Microsoft Excel Templates, problem of Of Employment Ojazlink, formally specifying and verifying properties of protocol systems. Such systems are modeled by hierarchies of concurrent processes, where interprocess communication is achieved by message passing rather than through arbi trary shared variables. Based on Excel Templates this model, a methodology is developed for mechanically assisted protocol analysis. How To A Title Research Paper - Academic Writing. The Gypsy methodology for concurrent program verification is the point of Archives Excel Templates, departure for Global Logistics, much of this work.

A theory of event concept coherence is developed. It is Analysis shown that the pieces of Asset Purchase Agreement - 10+, event description which appear in a body of text can be gathered together and hierarchically organized using a dictionary of event/state concepts. This theory has been implemented in a computer system, NEXUS. The representations it produces are constructed in terms of seven coherence relations. The dictionary it uses was compiled from an Analysis Archives Excel Templates analysis of ten folk tales. Simple Invitation Letter Png And Vector For Free. The seven coherence relations uused are class/subclass, sequence/subsequence, coordinate, antecedent, precedent, consequent and sequel. Sequence/subsequence and coordinate are two kinds of whole/part relations. The other four relations are temporal; antecedent and precedent concepts come before an event, consequent and sequel concepts come after an event. Associations between concepts in the dictionary are also organized in terms of the seven coherence relations. Templates. Associated with the concepts in the dictionary are default values for its case related arguments. Sample Offer Ojazlink. Relationships between concepts in the dictionary are refined by attaching to Template Archives Excel each relationship in Asset Agreement - 10+ the dictionary a set of Analysis Template Archives, constraints on matching case arguments.
NEXUS uses the default values and the constraints to control the representation building process. The flexibility of the representation scheme is demonstrated by applying it to several diverse examples of narrative text in the literature, including script and plan based stories and speech acts. The feasibility of NEXUS is shown by Corporate ( Organizational applying it to eight samples of text and discussing in detail the results. Analysis Archives - Microsoft Templates.

The goal of this dissertation is to determine precisely how an object is moving in three-dimensional space and to determine the three-dimensional- relationship of points on Purple Letter Png And For Free Download the surface of the object. The only information available is Archives - Microsoft Excel Templates a sequence of photographic images taken as the object moves across the field of view. The problem can be broken down into two sub-problems: the problem of determining the correspondence of feature points in one image with feature points in Of Employment Offer Ojazlink the next image; and once the correspondence is established, the Analysis - Microsoft Excel Templates, mathematical analysis required to determine the model and News Global Logistics, the movement. The correspondence problem, i.e., matching, is investigated using images of moving blocks. The corners of the blocks constitute the feature points to be put in correspondence between images. Several matching methods are combined into a hierarchy so that if one method fails another method can take over to help complete the matching process. The top level of the hierarchy matches by searching for Archives Excel Templates, feature points in the image of expected positions as computed from the expected movement of the object. The next hierarchy level matches an Of Employment Offer Letter | Docoments Ojazlink object by its position relative to other objects in the image, a property that is assumed to Template Archives - Microsoft Excel Templates change only Purchase Examples In Word, Pdf, gradually.
The next hierarchy level matches a block's faces by Analysis Archives - Microsoft Excel Templates relative position. Once faces have been matched, feature points bordering the How To Make A Title For A Research Paper Writing, faces not already matched by expected position can be put in correspondence. The mathematical analysis of the problem shows that there are an infinite number of geometrically similar solutions, each solution differing from the Archives Excel Templates, others by a scaling factor. A specific solution can be found by July setting the scaling to an arbitrary number. Two views of six feature points or three views of four feature points are required to find the model and the movement. For good accuracy, however, considerably more points, two views of twelve or fifteen points for example, are needed.

The University of Texas at Analysis Archives - Microsoft, Austin, Department of Computer Sciences. Edol 2012. Report# AI76-nl30 (dissertation). March 1976. Analysis. 120 pages. This thesis describes a computer program, called ISAAC, which can read, understand, solve, and draw pictures of physics problems stated in English. The program has solved twenty problems, most of which were taken unedited from high school and college physics texts. These problems involve rigid bodies in Structure, static equilibrium, and include such objects as levers, pivots, weights, ropes, and - Microsoft Templates, springs in various configurations.
An example of the class of problems solved is the following (from Schaum's Outline of Archives - Hnm Logistics, College The foot of a ladder rests against a vertical wall and on a horizontal floor. The top of the ladder is supported from the wall by a horizontal rope 30 ft. long. The ladder is 50 ft. long, weighs 100 lb. with its center of gravity 20 ft. from the Template Excel, foot, and a 150 lb. man is 10 ft. from the Sample Of Employment Letter Ojazlink, top. Determine the tension in the rope. In order to understand and solve such a problem, it is necessary to build an internal model of the problem in which the various objects and their interrelationships are adequately represented. Many of the relationships and features of the objects are not specified explicitly in the problem statement, but must be inferred by using common sense knowledge of what is usual. Excel. In the Letter Png And Vector Download, above example, we assume that the man is standing on the ladder although this is not explicitly stated.
Thus, the understanding of a physics problem is an active process in which the sentences of the problem statement are used to guide the construction of Analysis Template Excel, a mode which represents the ( Organizational Communications), relationships and features of objects with much greater detail and specificity than they are specified in the original problem statement. In this thesis, we investigate ways in which the Template Archives - Microsoft, meanings of phrases and sentences may be understood and related to Simple Png And Vector Download a developing model of the problem, using common sense knowledge (represented by computer programs) to aid the understanding process. Ways of representing objects and Template Archives Excel, their relationships are developed. Sample Of Employment | Docoments Ojazlink. These representations, which are originally created in response to the sentences in the problem statement, are further elaborated by processes which construct a geometric model of the problem, associate canonical objects (such as a point mass) with physical objects (such as a person), write and Template Archives - Microsoft, solve equations which describe the interactions of the objects, and construct a diagram of the Purple Download, problem. The techniques used in ISAAC have potential application in providing a natural-language interface between specialist programs and users who are not computer professionals, and in computer programs. for teaching physics and other technical subjects.

Hendrix, Gary G. Partitioned Networks for the Mathematical Modeling of Natural-Language Semantics, also NL-28. The University of Texas at Austin, Department of Computer Sciences. Report# AI75-1 (dissertation). 1975. The main concern of this dissertation is to advance a modeling scheme for use in artificially intelligent natural-language understanding which is capable of encoding knowledge about the Analysis Template Templates, world in a uniform, precise and How To Page For A Research - Academic, easily manipulatable form. As a prerequisite to understanding, fundamental concepts such as time, space, relation and change are formalized in Template Excel terms of set-theoretic constructs. Properly utilized, such constructs provide the basis for an abstract mathematical modeling of the nature of the world. Certain human-like organization schemes are imposed upon the set-theoretic models so that knowledge becomes grouped into bundles which are meaningful and convenient units for discourse. The organization schemes include a hierarchical classification, of objects and the packaging of sets of related changes into Communication Structure, Communications) units called processes. Processes are defined by process automata, structures capable of encoding discrete, continuous and Analysis Archives Templates, parallel change.
In conjunction with the hierarchy, process automata may be used to Corporate ( Organizational Structure, Communications) describe certain objects (both events and physical objects) at multiple levels of detail. Further, such automata may encode linguistic processes such as parsing and generation procedures. To facilitate use by computers, the set-theoretic modeling scheme is mapped onto a network representation. This network representation provides easily accessible cross-linkage between semantically related pieces of information, thus facilitating algorithms which interrogate the Archives Templates, information modeled in the network. A special network partitioning mechanism is used to delimit the Sample Agreement Examples In Word, Pdf, scopes of quantified variables, to distinguish hypothetical and imaginary situations from Analysis Template - Microsoft Templates reality, to encode the Asset Examples, multiple, alternative worlds considered in planning, and to focus attention at particular levels of detail. The modeling scheme uses a single paradigm to encode information relating to all types of objects including psychical objects, situations, times, events, categories and processes. NL-28.

GROPE embodies some major new ideas about representation and Purple Simple Png And Vector, processing of complex data structures.
