Повний текст джерелаModerna bilar har en mängd förarstödsystemer som syftar till att stödja föraren i sin dagligakörning. En av dem är Adaptive Cruise Control (ACC) som syftar till att hålla en hastighetspecificerad av föraren. Men denna hastighet kan uppfattas som för hög för vissa kurvoroch som resultat tar föraren kontrollen igen själv. För att undvika detta ska ett Curve SpeedAdaptation (CSA) system anpassa hastigheten för en kommande kurva. Ett sådant systembör sträva efter att efterlikna en förare och ta hänsyn till hur föraren skulle köra själv. Dethär examensarbetet syftar till att hitta så kallade körlägen som kan beskriva hur förare medolika körstilar kör genom kurvor med olika omständigheter genom att analysera manuellakörningar. En nestad klustringsmetod testas för att dela upp kurvor i grupper baserat påkörstilen som de kördes på och deras vägegenskaper. Resultaten visar att denna metod kanfånga olika körningsbeteenden genom kurvor. Vägtypen och hastighetsbegränsningen fören kurva verkar därmed ha huvudinverkan på körbeteendet. Att dela kurvorna först efterderas körstil följt av vägegenskaper ger bättre körlägena. Men ytterligare förbättringar avklustringsmetoderna är nödvändig för att förbättra de erhållna körningsmetoderna. Resul-taten av detta examensarbetet kan utgöra grunden för utvecklingen av ett kurvhastighetsanpassningssystem som anpassar både för den enskilda föraren och speciella vägegenskaperför att förbättra förarens komfort.

Повний текст джерелаThe web data collection mode has been increasing in popularity since its creation, primarily due to its cost and time effective benefits. However, its non-probabilistic tendencies often bring doubts concerning the representativity of its results in comparison to a typical mode such as the telephone. This master’s thesis compares the non-probability web and probability telephone modes, often suggested by polling firms in the province of Quebec. It principally analyzes the eventual differences between both samples on their adaptation to the Lyme disease. More specifically, the three main goals of this study are: (1) to compare the representativeness of both samples with the census data in terms of their socio-demographic characteristics, (2) to compare those two survey modes regarding their respondents’ preventive behaviour estimates against the Lyme disease, and (3) to test the measurement invariance of the nonprobability (Web panel) and probability (telephone) samples’ preventive behaviour. The data comes from a study on the adaptation of prevention behaviors against Lyme disease. The web (n=956) and telephone samples (n=1003) are made of individuals, 18 years old and above, from low and significant risk regions. Results firstly reveal that neither survey is representative of the Canadian census of 2016. Secondly, results show that the non-response rate for Lyme disease prevention adaptive behaviors and other associated variables is higher in the web survey. However, the magnitude of this significance is nil for 19 out of 30 the items, and small for the other 11. Moreover, no important dissimilarities were found in comparing both samples’ estimates in terms of the behaviours’ prevalence and their determinants. Finally, the measurement invariance analyses on the index of adaptation to the Lyme disease show a similar structure of the index for both samples. In conclusion, although the web and telephone samples are different in some respects, their respondents tend to have similar behaviors of adaptation to the disease.

Повний текст джерелаSince their inception, bio-social models of human development suggested that differences in behavioral adaptation are correlated with underlying physiological processes. Among very young children such differences reflect variation in modes of adjustment to the dynamics of the immediate social setting this study examines relationships between children's adreno-cortical response and behavioral styles during entry into an unfamiliar peer group. Behavioral activities of 72 three year-olds (12 groups of 6 children) were recorded during the initial 15 minutes of group interaction. Cortisol levels were from saliva samples collected immediately before and 15 minutes after the group experience. Multiva : riate hierarchical analysis of observed activity revealed three primary modes of behavioral adjustment engaged, friendly and withdrawn social styles. Repeated measures analysis of cortisol responses revealed no systematic relation between styles of social adaptation and absolute levels of cortisol. However, comparison of pre- and post-test changes in cortisol levels showed significant stability for children classified as engaged and friendly; in contrast withdrawn children were more variable in their physiological reactions. These results illustrate differential constraints of the immediate social context on both physiological and behavioral functioning of young children. Findings support the view that active social involvement facilitates the regulation of underlying physiological processes

Повний текст джерелаThis thesis uses population genetics and statistical approaches to investigate early human demography, infer local adaptation in diverse sets of populations, and study the genetic basis for taste perception. Using a Bayesian approach, I evaluate the genetic evidence of a bottleneck between 190,000 and 130,000 years ago and find that the data is in favor of a model without bottleneck at this time point. I further develop a method to detect local adaptation based on frequencies of private haplotypes. Applied to large-scale human genotype data, this method detects known signals of positive selection but also permits to improve knowledge on potential adaptation events in humans. I further investigate patterns of adaptation in whole genome data based on a diverse set of African populations. The results from the regions potentially selected show that diet and pathogens are the common driving forces of adaptation in all studied populations. I last study taste perception in populations differing on lifestyle (hunter-gatherers, farmers and nomad herders). I present taste perception phenotypes for all tastes (sweet, bitter, sour, salty and umami) and relate them to high density genotype data. I show that taste and taste-involved genes have evolved with lifestyle. By performing an association study, I also show that variation in taste perception involves more genes than only the taste receptors genes.I covered several topics of human ancient demography and adaptation and show the utility of using large-scale genetic data to better understand human history

Повний текст джерелаThis thesis seeks to explain why teachers accept and do not accept simultaneously students with impairment in ordinary classes. Both quantitative (questionnaire) and qualitative (interviews) data enable us to identify the reasons that operate behind teachers’ negative and positive response towards including these students. The questionnaires were distributed to 723 teachers posted in urban, rural, public and private ordinary schools. Finally, a total of 506 questionnaires could be collected back. A total of 37 teachers who didn’t fill out the questionnaire were also selected for interviews. The analyses reveal that teachers respond in “big no, little yes” and “little no, big yes” manner. It means that their responses oscillate on the continuum ranging from segregation to inclusion. Those with “big no, little yes” basically have negative perception of the students with reduction of their overall identity to the observed disability without taking account of their potential. We analyzed both forms of data and interpreted teachers’ responses on acceptance, exclusionary barriers, and support, changes and orientation needs to explore the optimum possibilities for inclusive classes. Quantitative analysis shows that significant difference exists on acceptance among teachers due to schools’ type and their academic and professional qualification while no significant difference exists due to schools’ locality, their marital status and their gender. Both analyses confirm that teachers direly needed orientation to curtail their qualms and to accept and value the potentials of these students in ordinary schools in Pakistan

Повний текст джерелаThis thesis focuses on the ultimatum imposed by the climate change phenomenon in contemporary Western society : changing the model of society or risk collapse (Diamonds, 2006). The major ordealt hat is required was that of otherwise inhabit the Earth around another project : the fight against climate change. Many publications (Aykut, 2012 ; Dahan, 2015 ; Latour, 2015 ; Roques, 2013 ;Stengers, 2009) describe the inability of state institutions to build a common project to respond to climate challenges. In this situation, the "critical" studies note the important place that has taken the simulation at the expense of concrete and sustainable action. Climate modelling, political and economic simulations, sociological diagnoses, literary fiction, climate change is largely invested by the narrative. Our field immersions have shown that other scales of action are already actively seized ofthe climate deal. Cities and businesses are in fact more likely to take a position in the energy and climate challenge. It follows that some statements, by their position mediators had given way to concrete experiments. Taking a pragmatic approach, inspired by the l’Enquête sur les modes d’existence proposed by Latour, and enriched by the model of Économies de la Grandeur of Boltanski and Thevenot, this thesis attempts to describe the various modes of existence of the climate problem from territorial collectives. We also assuming the rear of influence cultural plans and attachments in producing climate strategies by local actors

Повний текст джерелаThis study investigates the consequences that contacts between British people and Native American populations had on their respective ways of life. There is a widespread cliché in people’s minds according to which only British people would have had (heavily) left their marks on the North American ground and peoples that they encountered. Nevertheless, and contrarily to this idea, we shall tackle here their reciprocal influence, that is the way in which Native tribes also deeply impacted British colonists’ everyday life in the New World. We were able to witness such an influence thanks to archaeological, historical and ethnohistorical evidence. Various angles of study were chosen for this paper: the cultural habits and behaviors directly or indirectly linked to food (how did people have access to food supplies? How were foodstuffs prepared or cooked? Were food and/or meals shared? Which social links and practices -if any- derived from such habits?...). We shall also have to present to the audience what Native people’s connections and attitudes towards other tribes, or colonists from different European nations, were. And these could have been friendly, diplomatic, economical or even hostile relationships, implying political management and thinking ahead of taking actions, which was commonly omitted in the past

Повний текст джерелаThe thesis aims to (i) valid, purify a short French version from “Children's Attributional Style Questionnaire, CASQ”, this one would be adapted in French culture and with sport children; (ii) examine the theoretical conceptual model of the attributional/explanatory style not only in sport but also in school context. It is based upon data stemming from the Attributional Reformulation of Helplessness Theory (e. G. , Abramson, Seligman, Teasdale, 1978). Despite its interest, we found a very little studies in school context for children have been realised, nothing of studies concerning the children in the sport context. The thesis consists of three parts: the first one presents the theoretical base of explanatory style theory, studies concerning the psychological effects of explanatory style for children and adolescents in many fields. In the second parts, using many methods and samples, we examine the psychometric proprieties of an experimental French version of CASQ (QEMEE), and purify a short version (QEMEE-R). Basing to this version and in order to examine many theoretical hypothesis, we contextualise a version in sport and in school context. In the third parts, we realised two studies in sport and school contexts. Basing to Eccles and Wigfield model (2002), we tested three hypotheses concerning the effect of the contextualised and/or general explanatory style to predict the result in sport and in school domains. These two studies confirm the existence of (i) hierarchical organisation of children's the explanatory style, (ii) not only two but four profiles of children's explanatory style. These result constitute an theatrical evaluation in explanatory style search

Повний текст джерелаThis study addresses the issue of implementing object-oriented software with adaptive characteristics, having as primary purpose simplify the implementing process. The key theoretical basis consisted in adaptive technology and its application in various formalisms. Adaptive Object Model has been taken as comparison basis to solutions to implement adaptive systems. This study describes applications and a proposition to implement and model adaptive systems, through the extension of object concept with adaptive technology characteristics. It also evaluates the impact of applying adaptive devices in formalism with types. The results obtained demonstrate that adaptive technology is suitable for object-oriented languages and that UML diagrams are capable of presenting adaptive behavior appropriately with a small number of extensions.

Повний текст джерелаRodent populations are responsible for many economic and health problems. For these reasons different rodents species are called pests and particularly brown rats, house mice and black rats. Their populations need to be managed. This management involves health and environmental measures strictly necessary but is also based on the use of toxic chemicals. As part of chemical control, the AVKs are currently the most commonly used molecules. These AVKs inhibit blood coagulation and are the cause of fatal bleeding. The pharmacological target of AVK is the VKOR enzymatic activity, encoded by the vkorc1 gene. However, the intensive use of AVKs since the 1950s has led to the development of resistance to these molecules. The target resistance has been well studied in the brown rat, but little is known in the house mouse and the black rat

Повний текст джерелаThis thesis studies, in a psychodynamic register, the ways of adaptation and conflictualization created by school. Adaptation is defined as a dynamic process setting in action two moments of appropriation of the adaptative demands : the alternation and the alternative. Those two moments are supposed to set two capacities in action : the alternation sets in action both capacities of separation and succession and the alternative, both capacities of forsaking and transformation. Alternation and alternative both summon up specific forms of tolerance to frustration. The research deals with 109 children (aged 8 years odl) taking an ordinary course, and 26 children (11 years old) who have school difficulties and are about to be orientated towards a special course. The study takes in consideration the school results, a school adaptation questionnaire and an original drawing technique that aims to set in action the capacities of alternation and alternative. The elaboration of the test and the analysis of the two parts of the drawings are presented. Examples are given. The ways of managing the alternation are studied according to the axes of separation, succession and tolerance to frustration. The analysis of separation is mostly based on the drawing of the way from home to school and on the drawing of the house. Different modalities of managing the succession are presented (absolute or relative succession, no succession). Frustration is approached in its relationship with working and playing. The ways of managing the alternative are studied according to the axes of forsaking, transformation and tolerance to frustration. Three ways of managing the alternative are presented : majorating alternative (relative and creative alternatives), minorating alternative (alternative by disappearing, by regression, by protection, by degradation, by gulliverization, by conjuring, by confabulation), and the absence of alternative (alternatives by transformation and by a-transformation)

Повний текст джерелаThis thesis analyzes the multiple facets of the migratory experiences of Ivorians who arrived in Europe between the end of the 1990s and the end of the years 2000s. This work is based on a transnational and comparative approach and takes place in three different settings: Ivory Coast, France, and Italy. Although rooted primarily in the discipline of anthropology, this study also draws on several other disciplines such as sociology, history of migration, human geography, philosophy, and immigration law.Over the course of multisite ethnographic surveys, carried out between 2007 and 2013 in the Parisian region, in Naples and Parma, as well as in Abidjan, I have conducted long-term observations and collected numerous life histories and accounts of migration.The complexity of migratory routes undertaken by migrants is discussed in this study, as well as the development of their existential trajectories. We have described the profiles of these migrants, going beyond the categories assigned to them by the state policy, and focusing on the evolution of their lives in Europe.Particular attention was paid to the mechanisms of reproduction of contemporary Ivorian migration, which depend not only on the crises that have struck Ivory Coast since the end of the 1990s, but also on the power of the imagined and idealized West. This imagined ideal that has been built over the course of history, through the relations maintained by Ivory Coast and France during the colonial and postcolonial era, continues to develop in the present time, through representations on the media and the physical and material returns in the form of money transfers and revenues by immigrants already settled in the West. We have defined this migration as a "contemporary ritual", for which certain phases, specific to initiation rites, take place in the societies of origin, and are identifiable, although revisited in larger spatial and temporal frameworks.Two places in particular were the privileged sites of my investigations: the former Maison des Etudiants de Côte d'Ivoire in Paris, and the “ghetto” of “old houses” in via dell'Avvenire in Pianura, a district of Naples. Both served were squatted by many of these migrants and evicted in 2008 and in 2010, respectively. In the context of social marginalization stemming from European migration policies over the course of recent decades, which clearly operate against migrants from so-called “poor” countries, these sites turned out to be real social laboratories through which migrants have developed multiple practices of "dynamic resistance", practices created and implemented in order to re-build themselves and their lives and bypass different types of obstacles. These forms of dynamic resistance stem from the symbolic and constant dialogue that Ivorian migrants maintain with the cultural and social universe of their country of origin, and which helps them to reformulate and invent new ways of adapting to the new environments encountered during migration.The last part of the study deals with the work of Ivorian associations founded by migrants in France and Italy, in particular the hometown associations and those whose membership is defined by national origin. By describing their different missions, the modalities of their activities, and the meanings that members assign to their participation, these social productions bear witness to another intimate aspect through which the transnational dimension of Ivorian migration is expressed

Повний текст джерелаThe Internet of Things (IoT) is covering little by little every aspect on our lives. As these systems become more pervasive, the need of managing this complex infrastructure comes with several challenges. Indeed, plenty of small interconnected devices are now providing more than a service in several aspects of our everyday life, which need to be adapted to new contexts without the interruption of such services. However, this new computing system differs from classical Internet systems mainly on the type, physical size and access of the nodes. Thus, typical methods to manage the distributed software layer on large distributed systems as usual cannot be employed on this context. Indeed, this is due to the very different capacities on computing power and network connectivity, which are very constrained for IoT devices. Moreover, the complexity which was before managed by experts on several fields, such as embedded systems and Wireless Sensor Networks (WSN), is now increased by the larger quantity and heterogeneity of the node’s software and hardware. Therefore, we need efficient methods to manage the software layer of these systems, taking into account the very limited resources. This underlying hardware infrastructure raises new challenges in the way we administrate the software layer of these systems. These challenges can be divided into: intra-node, on which we face the limited memory and CPU of IoT nodes, in order to manage the software layer and ; inter-node, on which a new way to distribute the updates is needed, due to the different network topology and cost in energy for battery powered devices. Indeed, the limited computing power and battery life of each node combined with the very distributed nature of these systems, greatly adds complexity to the distributed software layer management. Software reconfiguration of nodes in the Internet of Things is a major concern for various application fields. In particular, distributing the code of updated or new software features to their final node destination in order to adapt it to new requirements, has a huge impact on energy consumption. Most current algorithms for disseminating code over the air (OTA) are meant to disseminate a complete firmware through small chunks and are often implemented at the network layer, thus ignoring all guiding information from the application layer. First contribution: A models@runtime engine able to represent an IoT running application on resource constrained nodes. The transformation of the Kevoree meta-model into C code to meet the specific memory constraints of an IoT device was performed, as well as the proposition of modelling tools to manipulate a model@runtime. Second contribution: Component decoupling of an IoT system as well as an efficient component distribution algorithm. Components decoupling of an application in the context of the IoT facilitates its representation on the model@runtime, while it provides a way to easily change its behaviour by adding/removing components and changing their parameters. In addition, a mechanism to distribute such components using a new algorithm, called Calpulli is proposed

Повний текст джерелаAutonomous Connected Vehicles (ACVs) are Cyber-physical systems (CPS) where the computationalworld and the real one meet. These systems require a rigorous validation processthat starts at design phase and continues after the software deployment. Models@Runtimehas appeared as a new paradigm for continuously monitoring software systems execution inorder to enable adaptations whenever a change, a failure or a bug is introduced in the executionenvironment. In this thesis, we are going to tackle ACVs environment where vehicles tries tocollaborate and share their data in a secure manner.Different modeling approaches are already used for expressing access control requirementsin order to impose security policies. However, their validation tools do not consider the impactsof the interaction between the functional and the security requirements. This interaction canlead to unexpected security breaches during the system execution and its potential runtimeadaptations. Also, the real-time prediction of traffic states using crowd sourcing data could beuseful for proposition adaptations to AVCs cooperation models. Nevertheless, it has not beensufficiently studied yet. To overcome these limitations, many issues should be addressed:• The evolution of the system functional part must be considered during the validation ofthe security policy and attack scenarios must be generated automatically.• An approach for designing and automatically detecting security anti-patterns might bedeveloped. Furthermore, new reconfigurations for access control policies also must befound, validated and deployed efficiently at runtime.• ACVs need to observe and analyze their complex environment, containing big-datastreams to recommend new cooperation models, in near real-time.In this thesis, we build an approach for sensing the ACVs environment, validating its accesscontrol models and securely reconfiguring it on the fly. We cover three aspects:• We propose an approach for guiding security models checkers to find the attack scenariosat design time automatically.• We design anti-patterns to guide the validation process. Then, we develop an algorithmto detect them automatically during models reconfigurations. Also, we design a mechanismfor reconfiguring the access control model and we develop a lightweight modularframework for an efficient deployment of new reconfigurations.• We build an approach for the real-time monitoring of dynamic data streams to proposeadaptations for the access policy at runtime.Our proposed approach was validated using several examples related o ACVs. the results ofour experimentations prove the feasibility of this approach

Повний текст джерелаLa detección de peatones es crucial para los sistemas de asistencia a la conducción (ADAS). Disponer de un clasificador preciso es fundamental para un detector de peatones basado en visión. Al entrenar un clasificador, se asume que las características de los datos de entrenamiento siguen la misma distribución de probabilidad que las de los datos de prueba. Sin embargo, en la práctica, esta asunción puede no cumplirse debido a diferentes causas. En estos casos, en la comunidad de visión por computador cada vez es más común utilizar técnicas que permiten adaptar los clasificadores existentes de su entorno de entrenamiento (dominio de origen) al nuevo entorno de prueba (dominio de destino). En esta tesis nos centramos en la adaptación de dominio de los detectores de peatones basados en modelos deformables basados en partes (DPMs). Como prueba de concepto, usamos como dominio de origen datos sintéticos (mundo virtual) y adaptamos el detector DPM entrenado en el mundo virtual para funcionar en diferentes escenarios reales. Comenzamos explotando al máximo las capacidades de detección del DPM entrenado en datos del mundo virtual pero, aun así, al aplicarlo a diferentes conjuntos del mundo real, el detector todavía pierde poder de discriminaci ón debido a las diferencias entre el mundo virtual y el real. Es por ello que nos centramos en la adaptación de dominio del DPM. Para comenzar, consideramos un único dominio de origen para adaptarlo a un único dominio de destino mediante dos métodos de aprendizaje por lotes, el A-SSVM y SA-SSVM. Después, lo ampliamos a trabajar con múltiples (sub-)dominios mediante una adaptación progresiva usando una jerarquía adaptativa basada en SSVM (HA-SSVM) en el proceso de optimización. Finalmente, extendimos HA-SSVM para conseguir un detector que se adapte de forma progresiva y sin intervención humana al dominio de destino. Cabe destacar que ninguno de los métodos propuestos en esta tesis requieren visitar los datos del dominio de origen. La evaluación de los resultados, realizadas con el sistema de evaluación de Caltech, muestran que el SA-SSVM mejora ligeramente respecto al A-SSVM y mejora en 15 puntos respecto al detector no adaptado. El modelo jerárquico entrenado mediante el HA-SSVM todavía mejora más los resultados de la adaptación de dominio. Finalmente, el método secuencial de adaptación de domino ha demostrado que puede obtener resultados comparables a la adaptación por lotes pero sin necesidad de etiquetar manualmente ningún ejemplo del dominio de destino. La adaptación de domino aplicada a la detección de peatones es de gran importancia y es un área que se encuentra relativamente sin explorar. Deseamos que esta tesis pueda sentar las bases del trabajo futuro en esta área.
On-board pedestrian detection is crucial for Advanced Driver Assistance Systems (ADAS). An accurate classi cation is fundamental for vision-based pedestrian detection. The underlying assumption for learning classi ers is that the training set and the deployment environment (testing) follow the same probability distribution regarding the features used by the classi ers. However, in practice, there are di erent reasons that can break this constancy assumption. Accordingly, reusing existing classi ers by adapting them from the previous training environment (source domain) to the new testing one (target domain) is an approach with increasing acceptance in the computer vision community. In this thesis we focus on the domain adaptation of deformable part-based models (DPMs) for pedestrian detection. As a prof of concept, we use a computer graphic based synthetic dataset, i.e. a virtual world, as the source domain, and adapt the virtual-world trained DPM detector to various real-world dataset. We start by exploiting the maximum detection accuracy of the virtual-world trained DPM. Even though, when operating in various real-world datasets, the virtualworld trained detector still su er from accuracy degradation due to the domain gap of virtual and real worlds. We then focus on domain adaptation of DPM. At the rst step, we consider single source and single target domain adaptation and propose two batch learning methods, namely A-SSVM and SA-SSVM. Later, we further consider leveraging multiple target (sub-)domains for progressive domain adaptation and propose a hierarchical adaptive structured SVM (HA-SSVM) for optimization. Finally, we extend HA-SSVM for the challenging online domain adaptation problem, aiming at making the detector to automatically adapt to the target domain online, without any human intervention. All of the proposed methods in this thesis do not require revisiting source domain data. The evaluations are done on the Caltech pedestrian detection benchmark. Results show that SA-SSVM slightly outperforms A-SSVM and avoids accuracy drops as high as 15 points when comparing with a non-adapted detector. The hierarchical model learned by HA-SSVM further boosts the domain adaptation performance. Finally, the online domain adaptation method has demonstrated that it can achieve comparable accuracy to the batch learned models while not requiring manually label target domain examples. Domain adaptation for pedestrian detection is of paramount importance and a relatively unexplored area. We humbly hope the work in this thesis could provide foundations for future work in this area.

Повний текст джерелаOften dismissed as the production of second-hand literature, though constantly used by modern stage directors and playwrights, adaptation has frequently been neglected by critics; barely theorised by those who practice it, it has been approached with an approximate definition. Through the study of thirty novels and short stories − ranging from Honoré d'Urfé's L’Astrée (1607-1625) to Saint-Réal’s Dom Carlos (1672) − and the study of some eighty theatrical adaptations, this work analyses the theatrical adaptation of narrative fictions as a coherent writing practice, which each and every play embodies in a different way. Starting with a clear definition of what theatrical adaptation means, then proceeding with a careful reading of the works and a detailed review of contemporary theories, we build tools to analyse this corpus and avoid the aporias adaptation theories have usually been confronted with. This reading of adaptation, based on rhetorics, enables us to follow the process of adaptative writing step by step through its various techniques − from the selection of material within the novel to the designing and actual writing of the play to its final staging. Thus we define the poetics of a transmodal adaptation, which reinvents the working of rhetorical categories and questions the potentiality of drama as a semiotic medium. Adaptation therefore challenges literary genres − sometimes confirming their topoï, sometimes creating new forms − and thus tackles aesthetics-related issues. Theatrical adaptation appears as a field of literary experimentation and formal innovation, within which intertextual references reverberate and multiply in various levels of reading. Exhibiting its second-hand nature and therefore its literary quality, theatrical adaptation rightly deserves to be read as a major contribution to the French seventeenth-century dramatic literature, to which it gives back its density and richness

Повний текст джерелаPhotorealistic modeling of humans in computer graphics is of special interest because it is required for modern movie- and computer game productions. Modeling realistic human models is relatively simple with current modeling software, but modeling an existing real person in detail is still a very cumbersome task. This dissertation focuses on realistic and automatic modeling as well as tracking human body motion. A skinning based approach is chosen to support efficient realistic animation. For increased realism, an artifact-free skinning function is enhanced to support blending the influence of multiple kinematic joints. As a result, natural appearance is supported for a wide range of complex motions. To setup a subject-specific model, an automatic and data-driven optimization framework is introduced. Registered, watertight example meshes of different poses are used as input. Using an efficient loop, all components of the animatable model are optimized to closely resemble the training data: vertices, kinematic joints and skinning weights. For the purpose of tracking sequences of noisy, partial 3D observations, a markerless motion capture method with simultaneous detailed model adaptation is proposed. The non-parametric formulation supports free-form deformation of the model’s shape as well as unconstrained adaptation of the kinematic joints, thereby allowing to extract individual peculiarities of the captured subject. Integrated a-prior knowledge on human shape and pose, extracted from training data, ensures that the adapted models maintain a natural and realistic appearance. The result is an animatable model adapted to the captured subject as well as a sequence of animation parameters, faithfully resembling the input data. Altogether, the presented approaches provide realistic and automatic modeling of human characters accurately resembling sequences of 3D input data.

Повний текст джерелаDie Entwicklung selbst-adaptiver Software erfordert die Konstruktion einer sogenannten "Adaptation Engine", die mittels Feedbackschleifen die unterliegende Software steuert und anpasst. Die Anpassung selbst wird häufig mittels Laufzeitmodellen, die die laufende Software repräsentieren, und Aktivitäten wie beispielsweise Analyse und Planung, die diese Laufzeitmodelle nutzen, beschrieben. Um das Zusammenspiel zwischen Laufzeitmodellen und Aktivitäten systematisch zu erfassen, wurden Megamodelle zur Laufzeit für selbst-adaptive Software vorgeschlagen. Ein Megamodell zur Laufzeit ist ein spezielles Laufzeitmodell, dessen Elemente Aktivitäten und andere Laufzeitmodelle sind. Folglich erfasst ein Megamodell das Zusammenspiel zwischen verschiedenen Laufzeitmodellen und zwischen Aktivitäten und Laufzeitmodellen als auch die Aktivierung und Ausführung der Aktivitäten. Darauf aufbauend präsentieren wir in diesem Artikel eine Modellierungssprache für ausführbare Megamodelle zur Laufzeit, EUREMA genannt, die aufgrund eines modellgetriebenen Ansatzes die Entwicklung selbst-adaptiver Software erleichtert. Der Ansatz umfasst eine domänen-spezifische Modellierungssprache und einen Laufzeit-Interpreter für Adaptation Engines, insbesondere für Feedbackschleifen. EUREMA Megamodelle werden über die Spezifikationsphase hinaus explizit zur Laufzeit genutzt, um mittels Interpreter Feedbackschleifen direkt auszuführen. Zusätzlich können Megamodelle zur Laufzeit dynamisch geändert werden, um Feedbackschleifen anzupassen. Daher unterstützt EUREMA die Entwicklung selbst-adaptiver Software durch die explizite Spezifikation von Feedbackschleifen, der verwendeten Laufzeitmodelle, und Adaptionsaktivitäten auf einer höheren Abstraktionsebene. Darüber hinaus ermöglicht EUREMA komplexe Lösungskonzepte, die mehrere Feedbackschleifen und deren Interaktion wie auch die hierarchische Komposition von Feedbackschleifen umfassen. Dies unterstützt schließlich das integrierte Zusammenspiel von Selbst-Adaption und Wartung für die Evolution der Software.

Повний текст джерелаDifferences between training and testing conditions may significantly degrade recognition accuracy in automatic speech recognition (ASR) systems. Adaptation is an efficient way to reduce the mismatch between models and data from a particular speaker or channel. There are two dominant types of acoustic models (AMs) used in ASR: Gaussian mixture models (GMMs) and deep neural networks (DNNs). The GMM hidden Markov model (GMM-HMM) approach has been one of the most common technique in ASR systems for many decades. Speaker adaptation is very effective for these AMs and various adaptation techniques have been developed for them. On the other hand, DNN-HMM AMs have recently achieved big advances and outperformed GMM-HMM models for various ASR tasks. However, speaker adaptation is still very challenging for these AMs. Many adaptation algorithms that work well for GMMs systems cannot be easily applied to DNNs because of the different nature of these models. The main purpose of this thesis is to develop a method for efficient transfer of adaptation algorithms from the GMM framework to DNN models. A novel approach for speaker adaptation of DNN AMs is proposed and investigated. The idea of this approach is based on using so-called GMM-derived features as input to a DNN. The proposed technique provides a general framework for transferring adaptation algorithms, developed for GMMs, to DNN adaptation. It is explored for various state-of-the-art ASR systems and is shown to be effective in comparison with other speaker adaptation techniques and complementary to them

Повний текст джерелаThis thesis aims to propose an architecture that addresses the design, supervision, management and adaptation of an interactive experience. We therefore propose a complete framework to facilitate the modeling phase of an interactive system and guarantee sufficient flexibility to achieve the objectives of complexity, scalability, adaptability and improvement through automatic learning. For this purpose, the formal model, CIT, based on two layers of description was introduced. The dynamic supervision process consists in controlling the interactive experience with regard to the formal model, based on networks of timed input/output automata. Two softwares, CELTIC (Common Editor for Location Time Interaction and Content) and EDAIN (Execution Driver based on Artificial INtelligence), implementing the CIT model and the activity supervision engine respectively, were developed during this thesis

models, having different correlations, constants and boundary conditions are selected to be adapted into the base solver. The basic equations regarding the base Navier-Stokes solver to which the turbulence models are implemented presented by briefly explaining the outputs obtained from the solver. Numerical work regarding the implementation of turbulence models into the base solver is given in steps of non-dimensionalization, transformation of equations into generalized coordinate system, numerical scheme, discretization, boundary and initial conditions and limitations. These sections of implementation are investigated and presented in detail with providing every steps of work accomplished. Certain trial problems are solved and outputs are compared with experimental data. Solutions for fluid flow over flat plate, in free shear, over cylinder and airfoil are demonstrated. Airfoil validation test cases are analyzed in detail. For three dimensional applications, computation of flow over a wing is accomplished and pressure distributions from certain sections are compared with experimental data.
