Abstract:
How does the brain translate an internal representation of an object into a decision about the object's category? Recent studies have uncovered the structure of object representations in inferior temporal cortex (IT) using multivariate pattern analysis methods. These studies have shown that representations of individual object exemplars in IT occupy distinct locations in a high-dimensional activation space, with object exemplar representations clustering into distinguishable regions based on category (e.g., animate vs. inanimate objects). In this study, we hypothesized that a representational boundary between category representations in this activation space also constitutes a decision boundary for categorization. We show that behavioral RTs for categorizing objects are well described by our activation space hypothesis. Interpreted in terms of classical and contemporary models of decision-making, our results suggest that the process of settling on an internal representation of a stimulus is itself partially constitutive of decision-making for object categorization.

Abstract:
How long did it take you to read this sentence? Chances are your response is a ball park estimate and its value depends on how fast you have scanned the text, how prepared you have been for this question, perhaps your mood or how much attention you have paid to these words. Time perception is here addressed in three sections. The first section summarizes theoretical difficulties in time perception research, specifically those pertaining to the representation of time and temporal processing. The second section reviews non-exhaustively temporal effects in multisensory perception. Sensory modalities interact in temporal judgement tasks, suggesting that (i) at some level of sensory analysis, the temporal properties across senses can be integrated in building a time percept and (ii) the representational format across senses is compatible for establishing such a percept. In the last section, a two-step analysis of temporal properties is sketched out. In the first step, it is proposed that temporal properties are automatically encoded at early stages of sensory analysis, thus providing the raw material for the building of a time percept; in the second step, time representations become available to perception through attentional gating of the raw temporal representations and via re-encoding into abstract representations.

Abstract:
Representation of temporal and spatial information for the Semantic Web often involves qualitative defined information (i.e., information described using natural language terms such as “before” or “overlaps”) since precise dates or coordinates are not always available. This work proposes several temporal representations for time points and intervals and spatial topological representations in ontologies by means of OWL properties and reasoning rules in SWRL. All representations are fully compliant with existing Semantic Web standards and W3C recommendations. Although qualitative representations for temporal interval and point relations and spatial topological relations exist, this is the first work proposing representations combining qualitative and quantitative information for the Semantic Web. In addition to this, several existing and proposed approaches are compared using different reasoners and experimental results are presented in detail. The proposed approach is applied to topological relations (RCC5 and RCC8) supporting both qualitative and quantitative (i.e., using coordinates) spatial relations. Experimental results illustrate that reasoning performance differs greatly between different representations and reasoners. To the best of our knowledge, this is the first such experimental evaluation of both qualitative and quantitative Semantic Web temporal and spatial representations. In addition to the above, querying performance using SPARQL is evaluated. Evaluation results demonstrate that extracting qualitative relations from quantitative representations using reasoning rules and querying qualitative relations instead of directly querying quantitative representations increases performance at query time.

Abstract:
In this paper canonical quantum gravity on noncommutative space–time is considered. The corresponding generalized classical theory is formulated by using the Moyal star product, which enables the representation of the field quantities depending on noncommuting coordinates by generalized quantities depending on usual coordinates. But not only the classical theory has to be generalized in analogy to other field theories. Besides, the necessity arises to replace the commutator between the gravitational field operator and its canonical conjugated quantity by a corresponding generalized expression on noncommutative space–time. Accordingly the transition to the quantum theory has also to be performed in a generalized way and leads to extended representations of the quantum theoretical operators. If the generalized representations of the operators are inserted to the generalized constraints, one obtains the corresponding generalized quantum constraints including the Hamiltonian constraint as dynamical constraint. After considering quantum geometrodynamics under incorporation of a coupling to matter fields, the theory is transferred to the Ashtekar formalism. The holonomy representation of the gravitational field as it is used in loop quantum gravity opens the possibility to calculate the corresponding generalized area operator.

Abstract:
An analytical framework is developed that permits the input-output representations of discrete-time linear time-varying (LTV) systems in terms of biorthogonal bases on compact time intervals. Using these representations, the companion paper, Part II develops computational procedures for rapid identification of fast nonsmooth LTV systems based on short data records. One of the representations proposed is also used in H. Zhao and J. Bentsman, “Block Diagram Reduction of the Interconnected Linear Time-Varying Systems in the Time Frequency Domain,” accepted for publication by Multidimensional Systems and Signal Processing to form system interconnections, or wavelet networks, and develop subsystem connectibility conditions and reduction rules. Under the assumption that the inputs and the outputs of the plants considered in the present work belong to lp spaces, where p=2 or p=∞, their impulse responses are shown to belong to Banach spaces. Further on, by demonstrating that the set of all bounded-input bounded-output (BIBO) stable discrete-time LTV systems is a Banach space, the system representation problem is shown to be reducible to the linear approximation problem in the Banach space setting, with the approximation errors converging to zero as the number of terms in the representation increases. Three types of LTV system representation, based on the input-side, the output-side, and the input-output transformations, are developed and the suitability of each representation for matching a particular type of the LTV system behavior is indicated.

FUNDAÇÃO DE APOIO À PESQUISA DO ESTADO DO RIO DE JANEIRO
O objetivo desta dissertação é examinar o papel desempenhado pelas representações do tempo e do espaço no sistema crítico kantiano. Mas, diversas questões surgem a partir desta pesquisa e se nos incumbimos de respeitar o legado de Kant e o seu espírito metodológico não devemos negligenciá-las. Assim, com o intuito de lançar luz sobre um tema tão obscuro, o presente trabalho aceita o desafio, e o estabelece como ponto de partida, de expor os conceitos de tempo e de espaço por uma análise histórica. E sobre o terreno seguro da tradição filosófica podemos descansar e recobrar forças para continuar a seguir os passos de Kant e encontrar as origens da Estética Transcendental. Portanto, o centro desta investigação é determinar de forma precisa o sentido das representações do tempo e do espaço a suas implicações para a teoria do conhecimento de Kant. Finalmente, ao término desta tumultuada jornada teremos alcançado uma melhor compreensão sobre a relação das intuições do tempo e do espaço com a coisa em si mesma, e, a sua importância para o idealismo transcendental.
The task of this dissertation is to examine the role played by the time and space representations in Kant`s critical system. But, several questions emerge from this inquiry, and if we are to respect Kant`s legacy and his methodological spirit we shall not neglect them. Then, as an effort to shed light over such an obscure matter the present work accepts the challenge, and establishes it as a starting point, of expounding time and space concepts through a historical analysis. And on the solid grounds of the philosophical tradition we can rest and regain strength to continue following Kant`s steps and finding the origins of the Transcendental Aesthetics. Therefore, the core of this investigation is determining accurately the meaning of time and space representations and its implications to Kant`s theory of knowledge. Finally, at the end of this troubled journey we will have reached a better understanding of the relationship between the time and space intuitions and the thing-in-itself and its significance to the transcendental idealism.

Abstract:
This paper examines the history of installation art and explains the concept and themes within my installation component of the studio art major. It details how readymades, site-specificity, and an emphasis on experiential work all contributed to the creation of installation art as a medium. Next, I turn to my own work, exploring the theme of representing time and altering the perceptions of the viewer. Through a web of fishing line and tempered glass, the installation visually imitates a single, frozen moment of an explosion that the viewer can walk into and explore. The paper continues with a discussion of relevant themes in the work by contemporary artists Ori Gerst, Heide Fasnacht, Cornelia Parker, E.V. Day, Lee Bontecou, and James Turrell, and concludes with ideas for the continuation of the project in the spring 2014 semester.

Abstract:
The last decades have witnessed the resurgence of research on linguistic relativity, which provides empirical evidence of possible language effects on thought across various perceptual domains. This study investigated the linguistic relativity hypothesis in the abstract domain of time by looking at how L1 Chinese - L2 English bilinguals conceptualize time in two-dimensional space. English primarily relies on horizontal spatial items to talk about time (e.g., back to youth); in addition to horizontal spatial metaphors (e.g., ‘front year’), Chinese speakers also commonly use vertical metaphors to describe time (e.g., ‘up week’). If language has an effect on thought, then spatial-temporal metaphors should shape people’s temporal cognition. In this study, we examined whether spatial-temporal metaphors impact online processing of time and long-term habitual thinking about time. Experiment 1 showed that bilinguals could automatically access the timeline which corresponded to the immediate linguistic context. In Experiment 2, a majority of bilinguals demonstrated salient vertical bias for temporal reasoning, whereas a small number of participants relied on the horizontal axis to represent time. The dominant thinking patterns for time documented here (65% prefer a vertical representation of time; 35% horizontal) run counter to the fact that horizontal metaphors are twice as common in Chinese as vertical metaphors. Further, it was found that bilinguals who used English more frequently were more likely to have a less vertical bias, which suggested a role of L2 experience in conceptual representations. Taken together, the evidence in this study showed that spatial-temporal metaphors have both short-term and long-term effects on mental representations of time, but also that space-time mappings do not depend solely on linguistic factors.

Abstract:
Description Logics (DLs) are a family of logic-based knowledge representation (KR) formalisms designed to represent and reason about static conceptual knowledge in a semantically well-understood way. On the other hand, standard action formalisms are KR formalisms based on classical logic designed to model and reason about dynamic systems. The largest part of the present work is dedicated to integrating DLs with action formalisms, with the main goal of obtaining decidable action formalisms with an expressiveness significantly beyond propositional. To this end, we offer DL-tailored solutions to the frame and ramification problem. One of the main technical results is that standard reasoning problems about actions (executability and projection), as well as the plan existence problem are decidable if one restricts the logic for describing action pre- and post-conditions and the state of the world to decidable Description Logics. A smaller part of the work is related to decidable extensions of Description Logics with concrete datatypes, most importantly with those allowing to refer to the notions of space and time.

Abstract:
Advances in surface performance capture have enabled the reconstruction of real world scenes such as people and animals with a realism hard to achieve by an animator. The work presented in this thesis aims to develop techniques for interactive editing and manipulation of captured mesh sequences with the flexibility associated with conventional computer animation techniques. In particular, the application of Laplacian deformation for animation and compression of surface motion capture data is investigated. Laplacian deformation enables the manipulation of a mesh at a vertex level while maintaining its local geometric properties but lacks a mechanism for ensuring the preservation of its underlying physical structure. Motivated by this limitation, a learnt surface deformation basis constructed in the space of differential cqordinates is introduced. The incorporation of this basis into the Laplacian framework constrains the solution to the space of plausible deformations built from a set of examples, therefore preserving the structure of the mesh. The successful application of this approach to space-time editing together with a set of novel non-linear edit propagation techniques are presented. Representations for efficient storage of surface motion capture sequences, generally comprised of hundreds of frames with thousands of vertices, are investigated. A novel layered representation that exploits the articulated nature of the data is presented and compared with other compression techniques based on PCA and Laplacian deformation, with and without using the aforementioned surface deformation basis. The proposed layered representation achieves consistently high compression ratio with low maximum reconstruction errors in three test sequences from different characters.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Architecture, 2000.
Includes bibliographical references (leaves 52-54).
Although the notion of "space" in architecture is a relatively contemporary one, this research looks at the difference between the conception and representation of space and the actual material reality. With contemporary thought brought about by the modern measure, as architects formalize their ideas in representations, this paper argues that there arises a tendency to quantify and objectify the represented space and discount the experiential nature of the space. This research was initiated in reaction to this tendency to conceive of space as a given, formal static container in search of a wider notion of space as a product of interactions between various dynamics. Using small time based representational design experiments as well as specific precedents of conceptions and representations of space as running parallel points of reference; this investigation explores the element of time as one of the possible components of the various dynamics that produce space. Specifically, a non-chronological look at the modern, contemporary and pre-modern notion of time was taken to explore possible alternative conceptions and representations of space and time, contending that space is neither static or exclusive of time, nor is it a stage set for speed. In other words, this paper concludes that space and time are first and foremost products of experience.

Abstract:
HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. Two models in particular are of great interest to mathematicians, namely the Ising model of a magnet and the percolation model of a porous solid. These models in turn are part of the unifying framework of the random-cluster representation, a model for random graphs which was first studied by Fortuin and Kasteleyn in the 1970’s. The random-cluster representation has proved extremely useful in proving important facts about the Ising model and similar models. In this work we study the corresponding graphical framework for two related models. The first model is the transverse field quantum Ising model, an extension of the original Ising model which was introduced by Lieb, Schultz and Mattis in the 1960’s. The second model is the space–time percolation process, which is closely related to the contact model for the spread of disease. In Chapter 2 we define the appropriate space–time random-cluster model and explore a range of useful probabilistic techniques for studying it. The space– time Potts model emerges as a natural generalization of the quantum Ising model. The basic properties of the phase transitions in these models are treated in this chapter, such as the fact that there is at most one unbounded fk-cluster, and the resulting lower bound on the critical value in . In Chapter 3 we develop an alternative graphical representation of the quantum Ising model, called the random-parity representation. This representation is based on the random-current representation of the classical Ising model, and allows us to study in much greater detail the phase transition and critical behaviour. A major aim of this chapter is to prove sharpness of the phase transition in the quantum Ising model—a central issue in the theory— and to establish bounds on some critical exponents. We address these issues by using the random-parity representation to establish certain differential inequalities, integration of which gives the results. In Chapter 4 we explore some consequences and possible extensions of the results established in Chapters 2 and 3. For example, we determine the critical point for the quantum Ising model in and in ‘star-like’ geometries.
HTML clipboard Statistisk fysik syftar till att förklara ett materials makroskopiska egenskaper i termer av dess mikroskopiska struktur. En särskilt intressant egenskap är är fenomenet fasövergång, det vill säga en plötslig förändring i de makroskopiska egenskaperna när externa förutsättningar varieras. Två modeller är särskilt intressanta för en matematiker, nämligen Ising-modellen av en magnet och perkolationsmodellen av ett poröst material. Dessa två modeller sammanförs av den så-kallade fk-modellen, en slumpgrafsmodell som först studerades av Fortuin och Kasteleyn på 1970-talet. fk-modellen har sedermera visat sig vara extremt användbar för att bevisa viktiga resultat om Ising-modellen och liknande modeller. I den här avhandlingen studeras den motsvarande grafiska strukturen hos två näraliggande modeller. Den första av dessa är den kvantteoretiska Isingmodellen med transverst fält, vilken är en utveckling av den klassiska Isingmodellen och först studerades av Lieb, Schultz och Mattis på 1960-talet. Den andra modellen är rumtid-perkolation, som är nära besläktad med kontaktmodellen av infektionsspridning. I Kapitel 2 definieras rumtid-fk-modellen, och flera probabilistiska verktyg utforskas för att studera dess grundläggande egenskaper. Vi möter rumtid-Potts-modellen, som uppenbarar sig som en naturlig generalisering av den kvantteoretiska Ising-modellen. De viktigaste egenskaperna hos fasövergången i dessa modeller behandlas i detta kapitel, exempelvis det faktum att det i fk-modellen finns högst en obegränsad komponent, samt den undre gräns för det kritiska värdet som detta innebär. I Kapitel 3 utvecklas en alternativ grafisk framställning av den kvantteoretiska Ising-modellen, den så-kallade slumpparitetsframställningen. Denna är baserad på slumpflödesframställningen av den klassiska Ising-modellen, och är ett verktyg som låter oss studera fasövergången och gränsbeteendet mycket närmare. Huvudsyftet med detta kapitel är att bevisa att fasövergången är skarp—en central egenskap—samt att fastslå olikheter för vissa kritiska exponenter. Metoden består i att använda slumpparitetsframställningen för att härleda vissa differentialolikheter, vilka sedan kan integreras för att lägga fast att gränsen är skarp. I Kapitel 4 utforskas några konsekvenser, samt möjliga vidareutvecklingar, av resultaten i de tidigare kapitlen. Exempelvis bestäms det kritiska värdet hos den kvantteoretiska Ising-modellen på , samt i ‘stjärnliknankde’ geometrier.

Abstract:
This article deals with time-domain hydroelastic analysis of a marine structure. The convolution terms in the mathematical model are replaced by their alternative state-space representations whose parameters are obtained by using the realization theory. The mathematical model is validated by comparison to experimental results of a very flexible barge. Two types of time-domain simulations are performed: dynamic response of the initially inert structure to incident regular waves and transient response of the structure after it is released from a displaced condition in still water. The accuracy and the efficiency of the simulations based on the state-space model representations are compared to those that integrate the convolutions.

Full text
Abstract:
Autonomous marine vehicles (AMVs) are typically deployed for long periods of time in the ocean to monitor different physical, chemical, and biological processes. Given their limited energy budgets, it makes sense to consider motion plans that leverage the dynamics of the surrounding flow field so as to minimize energy usage for these vehicles. In this paper, we present two graph search based methods to compute energy optimal paths for AMVs in two-dimensional (2-D) time-varying flows. The novelty of the proposed algorithms lies in a unique discrete graph representation of the 3-D configuration space spanned by the spatio-temporal coordinates. This enables a more efficient traversal through the search space, as opposed to a full search of the spatio-temporal configuration space. Furthermore, the proposed strategy results in solutions that are closer to the global optimal when compared to greedy searches through the spatial coordinates alone. We demonstrate the proposed algorithms by computing optimal energy paths around the Channel Islands in the Santa Barbara bay using time-varying flow field forecasts generated by the Regional Ocean Model System. We verify the accuracy of the computed paths by comparing them with paths computed via an optimal control formulation.

Abstract:
Research methodology. The following methods were used in this research: general scientific methods (descriptive, analysis, synthesis, comparison) and special (structural, hermeneutic, narrative, method of content analysis). We identified words related to the concept of the enemy and determined the context in which they are used by the authors of the collections Results. The formats of reflection of military reality in collections of military documentaries are investigated. It is emphasized that the authors-observers of events as professional communicators form a vision of events based on categories understandable to the audience – «own» and «others». Instead, the authors-participants go events have more creative space and pay more attention to their own emotional state and reflections. It is defined how the enemy is depicted and what place he occupies in the military reality represented by the authors. It is emphasized that the authors reflect the enemy in different ways. In particular, the authors-observers of the events tried to form a comprehensive vision of the events, and therefore paid much attention to the opposite side of the military conflict. Authors-participants of the events tend to show the enemy as a mass to be opposed. In such collections, the enemy is specified only in the presence of evidence confirming the presence of Russians or militants. Novelty. The research for the first time investigates the methods of representation of mi­litary activity in the collections of Ukrainian military documentaries. The article is devoted to the analysis of how the authors represent the enemy. Practical importance. The analysis of collections of military documentaries will allow to study the phenomenon of war and to trace the peculiarities of the authors’ representation of military reality.
