▼ Hybrid models are those containing continuous and discontinuous behaviour. In constructing dynamic systems models, it is frequently desirable to abstract rapidly changing, highly nonlinear behaviour to a discontinuity. Bond graphs lend themselves to systems modelling by being multi-disciplinary and reflecting the physics of the system. One advantage is that they can produce a mathematical model in a form that simulates quickly and efficiently. Hybrid bond graphs are a logical development which could further improve speed and efficiency. A range of hybrid bond graph forms have been proposed which are suitable for either simulation or further analysis, but not both. None have reached common usage. A Hybrid bond graph method is proposed here which is suitable for simulation as well as providing engineering insight through analysis. This new method features a distinction between structural and parametric switching. The controlled junction is used for the former, and gives rise to dynamic causality. A controlled element is developed for the latter. Dynamic causality is unconstrained so as to aid insight, and a new notation is proposed. The junction structure matrix for the hybrid bond graph features Boolean terms to reflect the controlled junctions in the graph structure. This hybrid JSM is used to generate a mixed-Boolean state equation. When storage elements are in dynamic causality, the resulting system equation is implicit. The focus of this thesis is the exploitation of the model. The implicit form enables application of matrix-rank criteria from control theory, and control properties can be seen in the structure and causal assignment. An impulsive mode may occur when storage elements are in dynamic causality, but otherwise there are no energy losses associated with commutation because this method dictates the way discontinuities are abstracted. The main contribution is therefore a Hybrid Bond Graph which reflects the physics of commutating systems and offers engineering insight through the choice of controlled elements and dynamic causality. It generates a unique, implicit, mixed-Boolean system equation, describing all modes of operation. This form is suitable for both simulation and analysis.

▼ Complex systems are designed using the model-based design paradigm in which mathematical models of systems are created and checked against specifications. Cyber-physical systems (CPS) are complex systems in which the physical environment is sensed and controlled by computational or cyber elements possibly distributed over communication networks. Various aspects of CPS design such as physical dynamics, software, control, and communication networking must interoperate correctly for correct functioning of the systems. Modeling formalisms, analysis techniques and tools for designing these different aspects have evolved independently, and remain dissimilar and disparate. There is no unifying formalism in which one can model all these aspects equally well. Therefore, model-based design of CPS must make use of a collection of models in several different formalisms and use respective analysis methods and tools together to ensure correct system design. To enable doing this in a formal manner, this thesis develops a framework for multi-model verification of cyber-physical systems based on behavioral semantics. Heterogeneity arising from the different interacting aspects of CPS design must be addressed in order to enable system-level verification. In current practice, there is no principled approach that deals with this modeling heterogeneity within a formal framework. We develop behavioral semantics to address heterogeneity in a general yet formal manner. Our framework makes no assumptions about the specifics of any particular formalism, therefore it readily supports various formalisms, techniques and tools. Models can be analyzed independently in isolation, supporting separation of concerns. Mappings across heterogeneous semantic domains enable associations between analysis results. Interdependencies across different models and specifications can be formally represented as constraints over parameters and verification can be carried out in a semantically consistent manner. Composition of analysis results is supported both hierarchically across different levels of abstraction and structurally into interacting component models at a given level of abstraction. The theoretical concepts developed in the thesis are illustrated using a case study on the hierarchical heterogeneous verification of an automotive intersection collision avoidance system.

Afin de définir une conception optimale d’un système électromécanique, celui-ci doit intégrer des contraintes toujours plus drastiques et de nombreux phénomènes physiques issus de : l’électromagnétique, l’aérothermique, l’électronique, la mécanique et l’acoustique. L’originalité de cette thèse est de proposer une modélisation multi-physique pour la conception reposant sur des modèles à constantes localisées : solution intermédiaire entre la modélisation analytique et numérique. Ces différents modèles permettront l’étude et la conception sous contraintes d’une machine synchrone à aimants permanents dédiée pour la traction ferroviaire. Les résultats de simulations seront comparés à des résultats éléments finis mais aussi à des essais expérimentaux. Ce modèle multi-physique est entièrement paramétré afin d’être associé à des outils d’optimisation. On utilisera ici une optimisation par essaim de particules pour chercher des compromis entre différents objectifs sous forme de Front de Pareto. Dans ce papier, nous ciblerons les objectifs suivants : le couple d’origine électromagnétique et le bruit d’origine électromagnétique. Finalement une étude de sensibilité valide la robustesse de la conception retenue quand celle-ci est soumise aux contraintes de fabrication. L’objectif étant de poser les bases d’un outil d’aide à la décision pour le choix d’une machine électrique

In order to perform an optimal design of electromechanical system, the designer must take into account ever more stringent constraints and many physical phenomena from electric, magnetic, aeraulic, thermic, electronic, mechanic and acoustic. The originality of this thesis is to put forward a multi-physic design based on lumped models: halfway between analytical and numerical modeling. These models allow sizing a permanent magnet synchronous machine under constraints for rail traction. The results are validated with finite element simulations and experimental analysis. The multi-physic modeling is fully automated, parameterized, in order to combine the model with the optimization tool. We used here particle swarm optimization to search compromises between several objectives (Pareto Front). In this paper, we focus on electromagnetic torque and electromagnetic noise. Finally a sensitive study validates the robustness of selected design when it is subjected to manufacturing constraints. The aim of this work is to propose a decision tool to size electrical machines

▼ A cyber-physical system (CPS) typically consists of networked computational elements that control physical processes. As an integral part of CPS, the widespread deployment of communicable sensors makes the task of monitoring and control quite challenging especially from the viewpoint of scalability and complexity. This research investigates two unique aspects of overcoming such barriers, making a CPS more robust against data explosion and network vulnerabilities. First, the correlated characteristics of high-resolution sensor data are exploited to significantly reduce the fused data volume. Specifically, spatial, temporal and spatiotemporal compressed sensing approaches are applied to sample the measurements in compressed form. Such aggregation can directly be used in centralized static state estimation even for a nonlinear system. This approach results in a remarkable reduction in communication overhead as well as memory/storage requirement. Secondly, an agent based architecture is proposed, where the communicable sensors (identified as agents) also perform local information processing. Based on the local and underdetermined observation space, each agent can monitor only a specific subset of global CPS states, necessitating neighborhood information exchange. In this framework, we propose an agent based static state estimation encompassing local consensus and least square solution. Necessary bounds for the consensus weights are obtained through the maximum eigenvalue based convergence analysis and are verified for a radial power distribution network. The agent based formulation is also applied for a linear dynamical system and the consensus approach is found to exhibit better and more robust performance compared to a diffusion filter. The agent based Kalman consensus filter (AKCF) is further investigated, when the agents can choose between measurements and/or consensus, allowing the economic allocation of sensing and communication tasks as well as the temporary omission of faulty agents. The filter stability is guaranteed by deriving necessary consensus bounds through Lyapunov stability analysis. The states dynamically estimated from AKCF can be used for state-feedback control in a model predictive fashion. The effect of lossy communication is investigated and critical bounds on the link failure rate and the degree of consensus that ensure stability of the agent based control are derived and verified via simulations.

La simulation constitue une approche majeure pour la conception, le développement, l’analyse et l’évolution des systèmes urbains. Dans le contexte de cette thèse, nous nous intéressons à la modélisation et à la simulation des déplacements de flux (piéton, véhicule, cycle) au sein d’environnements urbains. Le contexte industriel dans lequel s’inscrit également cette thèse impose de considérer les déplacements de chaque entité dans un univers modélisé en trois dimensions. Nous proposons d’aborder les nombreux défis scientifiques et technologiques en modélisant les flux sous la forme d’entités autonomes appelées agents. La simulation orientée-agent nécessite de définir trois mécanismes principaux : le comportement des agents, leurs interactions avec les autres agents et leurs interactions avec l’environnement dans lequel ils évoluent. Ce dernier modélise la structure du monde ainsi que sa dynamique endogène. Malheureusement, il reste difficile de trouver des modèles d’environnement répondant aux différentes problématiques scientifiques et technologiques abordées dans cette thèse. Par conséquent, nous proposons un modèle d'environnement, nommé HEDGE (HEterogenous Dual Graph Environment). Il est basé sur une décomposition de l’environnement en zones reliées par des liens de navigation et de perception. Cette structure de graphe est au centre de notre modèle. Elle a été conçue pour permettre une modélisation naturelle de l’environnement et une simulation efficace du système constitué par cet environnement et les agents. Les missions et les processus dynamiques de l’environnement sont modélisés à l’aide de mécanismes inspirés des lois de la Physique. Les actions fournies par les agents et par les algorithmes calculant la dynamique endogène de l’environnement sont des forces à appliquer aux objets du monde. Un modèle de détection et de résolution de conflits entre ces forces est utilisé afin de garantir un état cohérent du modèle de l’environnement. Dans la dernière partie de cette thèse, nous illustrons l’utilisation du modèle HEDGE dans le cadre de deux projets d’aménagement de la ville de Belfort et de sa communauté d’agglomérations Le produit de l’application de ce modèle est utilisé à des fins d’études techniques (études préliminaires, avant-projet), de communication (concertations et débats publics) et de promotion (expositions, valorisation) sous la forme de logiciels interactifs en 3D.

Simulation constitutes a major approach for the conception, development, analysis and evolution of urban systems. This thesis focusses on the modeling and simulation of movements (pedestrian, vehicle, cycle) within urban environments. The industrial context associated with this thesis requires to consider the movements of each entity in a three dimensional universe. In this thesis, we propose to address the scientific and technological challenges by using autonomous entities, called agents, to model the individuals. In agent-based simulation three elements must be defined: the agent behaviors, their interactions with other agents,…

▼ The purpose of this research is to develop a new approach to estimate the effective leakage area using the inverse modeling process as an alternative to the blower door test. An actual office building, which is the head quarter of Energy Efficiency Hub, was used as an example case in this study. The main principle of the inverse modeling process is comparing the real monitor boiler gas consumption with the result calculated from the EnergyPlus model with a dynamic infiltration rate input to find the best estimation of the parameter of effective leakage area (ELA). This thesis considers only the feasibility of replacing the blower door test with the calibration approach, so rather than attempting an automated calibration process based on inverse modeling we deal with generating a first estimate and consider the role of model uncertainties that would make the proposed method less feasible. There are five steps of the whole process. First, we need to customize our own actual weather data (AMY) needed by the energy model (EnergyPlus model), which can help increase our quality of the result. Second, create the building energy model in EnergyPlus. Third, create a multi-zone model using CONTAM with different ELA estimation of each facade to calculate the dynamic infiltration rate of each ELA estimate. Fourth, input the dynamic infiltration rate got from the CONTAM model to EnergyPlus model and output the boiler energy consumption. Fifth, compare the boiler gas consumption from the model and the real monitor data and find the best match between the two and the corresponding ELA, which gives the best estimate from the whole inverse modeling process. From the simulation result comparison, the best estimation of the total building ELA from the inverse modeling process is the 23437cm2 at 4pa, while the result from the blower door test is 10483cm2 at 4pa. Because of the insufficient information of the building and also the uncertainty of the input parameters, the study has not led to a definite statement whether the proposed calibration of the ELA with consumption data can replace a blower door test to get an equally valid or even better ELA estimate, but it looks feasible. As this this case study is done in a deterministic context, the full feasibility test should be conducted under uncertainty. A first step towards this will talk be discussed in chapter 4.

▼ The topic of this dissertation is the anatomical, psychological, and cultural examination of a human face in order to effectively construct an anatomy-driven 3D virtual face customization and action model. In order to gain a broad perspective of all aspects of a face, theories and methodology from the fields of art, engineering, anatomy, psychology, and cultural studies have been analyzed and implemented. The computer generated facial customization and action model were designed based on the collected data. Using this customization system, culturally-specific attractive face in Korean popular culture, “kot-mi-nam (flower-like beautiful guy),” was modeled and analyzed as a case study. The “kot-mi-nam” phenomenon is overviewed in textual, visual, and contextual aspects, which reveals the gender- and sexuality-fluidity of its masculinity. The analysis and the actual development of the model organically co-construct each other requiring an interwoven process. Chapter 1 introduces anatomical studies of a human face, psychological theories of face recognition and an attractive face, and state-of-the-art face construction projects in the various fields. Chapter 2 and 3 present the Bezier curve-based 3D facial customization (BCFC) and Multi-layered Facial Action Model (MFAF) based on the analysis of human anatomy, to achieve a cost-effective yet realistic quality of facial animation without using 3D scanned data. In the experiments, results for the facial customization for gender, race, fat, and age showed that BCFC achieved enhanced performance of 25.20% compared to existing program Facegen , and 44.12% compared to Facial Studio. The experimental results also proved the realistic quality and effectiveness of MFAM compared with blend shape technique by enhancing 2.87% and 0.03% of facial area for happiness and anger expressions per second, respectively. In Chapter 4, according to the analysis based on BCFC, the 3D face of an average kot-mi-nam is close to gender neutral (male: 50.38%, female: 49.62%), and Caucasian (66.42-66.40%). Culturally-specific images can be misinterpreted in different cultures, due to their different languages, histories, and contexts. This research demonstrates that facial images can be affected by the cultural tastes of the makers and can also be interpreted differently by viewers in different cultures.

▼ Multi-core platforms represent the answer of the industry to the increasing demand for computational capabilities. In fact, multi-core platforms can deliver large computational power together with minimum costs, compact size, weight and power usage. Multi-core architectures however are shaking the very foundation of modern real-time computing theory, i.e. the assumption that worst case execution time (WCET) can be calculated on individual tasks to compute the schedulability of the complete system when tasks are running together. This fundamental assumption has been broadly accepted by classic scheduling theory for the past three decades; unfortunately, it is not even true in an approximate sense in a modern multi-core chip, and this leads to a lack of composability. Shared hardware resources like caches, main memory, and I/O buses are all sources of unpredictable timing behavior and temporal dependencies among real-time tasks running in parallel. As a result, certifying systems deployed using multi-core platforms is significantly more challenging compared to single-core implementations. In this work, we tackle the challenge of restoring the constant WCET assumption for real-time tasks deployed on multi-core systems. While predictability and performance determinism are of paramount importance in safety-critical applications, cost containment and time-to-market are dominant factors for the large-scale adoption of novel technologies. Hence, our work proposes solutions that can be adopted with commercially available components, also known as commercial-off-the-shelf (COTS) components. In order to achieve deterministic performance on COTS multi-core platforms, we propose software-level techniques to enforce usage control over shared hardware resources. We also demonstrate that when proper enforcement is performed, real-time analysis can be carried out efficiently. We focus our attention on two main multi-core architectural paradigms: cache-based and scratchpad-based platforms. On multi-core cache-based architectures, we design, implement and analyse a set of OS-level techniques that enforce hardware resource partitioning. In this context, we set two main goals. Our first objective is to achieve strong inter-core performance isolation in spite of inherent hardware resource sharing. On the other hand, our techniques are designed to remain transparent from an application perspective. This requirement allows for minimum re-engineering being required to port legacy single-core systems on multi-core platforms partitioned with the proposed techniques. On scratchpad-based platforms, we follow a different approach. In fact, we propose a redesign of the OS-level scheduling strategies. The goal is to include scratchpad space scheduling, as well as shared memory bus access, together with traditional processor time scheduling. The resulting resource co-scheduling strategy introduces a set of new challenges compared to processor-only scheduling. Nonetheless, it allows to significantly mitigate the problem of inter-core performance… Advisors/Committee Members: Caccamo, Marco (advisor), Caccamo, Marco (Committee Chair), Sha, Lui (committee member), Abdelzaher, Tarek F.
