Full textThis thesis is dedicated to sequential decision making (also known as multistage optimization) in uncertain complex environments. Studied algorithms are essentially applied to electricity production ("Unit Commitment" problems) and energy stock management (hydropower), in front of stochastic demand and water inflows. The manuscript is divided in 7 chapters and 4 parts: Part I, "General Introduction", Part II, "Background Review", Part III, "Contributions" and Part IV, "General Conclusion". This first chapter (Part I) introduces the context and motivation of our work, namely energy stock management. "Unit Commitment" (UC) problems are a classical example of "Sequential Decision Making" problem (SDM) applied to energy stock management. They are the central application of our work and in this chapter we explain main challenges arising with them (e.g. stochasticity, constraints, curse of dimensionality, ...). Classical frameworks for SDM problems are also introduced and common mistakes arising with them are be discussed. We also emphasize the consequences of these - too often neglected - mistakes and the importance of not underestimating their effects. Along this chapter, fundamental definitions commonly used with SDM problems are described. An overview of our main contributions concludes this first chapter. The second chapter (Part II) is a background review of the most classical algorithms used to solve SDM problems. Since the applications we try to solve are stochastic, we there focus on resolution methods for stochastic problems. We begin our study with classical Dynamic Programming methods to solve "Markov Decision Processes" (a special kind of SDM problems with Markovian random processes). We then introduce "Direct Policy Search", a widely used method in the Reinforcement Learning community. A distinction is be made between "Value Based" and "Policy Based" exploration methods. The third chapter (Part II) extends the previous one by covering the most classical algorithms used to solve UC's subtleties. It contains a state of the art of algorithms commonly used for energy stock management, mainly "Model Predictive Control", "Stochastic Dynamic Programming" and "Stochastic Dual Dynamic Programming". We briefly overview distinctive features and limitations of these methods. The fourth chapter (Part III) presents our main contribution: a new algorithm named "Direct Value Search" (DVS), designed to solve large scale unit commitment problems. We describe how it outperforms classical methods presented in the third chapter. We show that DVS is an "anytime" algorithm (users immediately get approximate results) which can handle large state spaces and large action spaces with non convexity constraints, and without assumption on the random process. Moreover, we explain how DVS can reduce modelling errors and can tackle challenges described in the first chapter, working on the "real" detailed problem without "cast" into a simplified model. Noisy optimisation is a key component of DVS algorithm; the fifth chapter (Part III) is dedicated to it. In this chapter, some theoretical convergence rate are studied and new convergence bounds are proved - under some assumptions and for given families of objective functions. Some variance reduction techniques aimed at improving the convergence rate of graybox noisy optimization problems are studied too in the last part of this chapter. Chapter sixth (Part III) is devoted to non-quasi-convex optimization. We prove that a variant of evolution strategy can reach a log-linear convergence rate with non-quasi-convex objective functions. Finally, the seventh chapter (Part IV) concludes and suggests some directions for future work

Full textComputer Vision (CV) is crucial for understanding and analyzing the driving scene to build more intelligent Advanced Driver Assistance Systems (ADAS). However, implementing CV-based ADAS in a real automotive environment is not straightforward. Indeed, CV algorithms combine the challenges of high computing performance and algorithm accuracy. To respond to these requirements, new heterogeneous circuits are developed. They consist of several processing units with different parallel computing technologies as GPU, dedicated accelerators, etc. To better exploit the performances of such architectures, different languages are required depending on the underlying parallel execution model. In this work, we investigate various parallel programming methodologies based on a complex case study of stereo vision. We introduce the relevant features and limitations of each approach. We evaluate the employed programming tools mainly in terms of computation performances and programming productivity. The feedback of this research is crucial for the development of future CV algorithms in adequacy with parallel architectures with a best compromise between computing performance, algorithm accuracy and programming efforts

Full textThe recent enthusiasm for the Internet of Objects as well as for satellite communications leads to the need for high-performance radio-frequency (RF) communication systems. In order to meet the constraints of the mass market, these systems must be compact and be as low power as possible. Beside, they are expected to address multiple communication standards and to adjust their performance to the environment, still in order to reduce the size and the power consumption. Currently, many works focus on the development of low-noise amplifiers (LNA), the most critical block of RF receivers. To address this purpose, the goal is to design multi-mode and multi-standard receivers. Hence, LNAs require design flows that can adapt to the different technologies and topologies in order to meet any given set of specifications. This thesis aims at the development of simple and accurate design methodologies for the implementation of low-noise amplifiers.The first proposed methodology is dedicated to the implementation of a LNA in COTS technology for spatial applications. This LNA offers a broadband matching to address several standards. It is designed to be part of an RF receiver for nano-satellites. Thus, the latter is first studied in order to determine the specifications based on the standards of the targeted applications.The second methodology is dedicated to the implementation of LNAs in CMOS technology for any kind of applications. This methodology is first illustrated with basic topologies and then applied to an highly linear inductorless LNA. The design methodology also enables a fair comparison between the topologies and also CMOS technologies, even the most advanced ones such as the 28 nm FDSOI.Finally, reconfigurability is added to the inductorless LNA, to address several standards while retaining the optimum sizing given by the previously introduced methodology. Indeed, the size and polarization of each transistor are digitally controlled in order to adjust the LNA's performance to a given standard. Furthermore, the study of N-path filters combined with the proposed LNA is explored to improve the linearity of the circuit

Full textAujourd’hui, la méthode des éléments finis est suffisamment développée pour apporter aux ingénieurs, une aide indispensable lors des étapes de conception et d’optimisation des produits manufacturés. Dans certains cas, cette aide dépasse la simple assistance technologique et permet de considérer des lois physiques dans l’intimité d’un milieu inaccessible aux expériences (fission et fusion nucléaire, propagation des fissures dans les matériaux,…). C’est dans ce contexte à la fois scientifique et technologique que porte notre contribution sur la formation du copeau. D’un point de vue applicatif et expérimental, notre étude est centrée sur l’usinage de l’alliage d’Aluminium A2024-T351. Cette étude a été accomplie avec 4 étapes principales. La première étape porte sur la mise au point d’un modèle numérique 2D, de coupe orthogonale en tournage. Ce travail permet de choisir des solutions de détails pour ce modèle numérique, aussi bien au niveau de la discrétisation et de la partition du maillage qu’au niveau du comportement du matériau usiné sur les aspects cruciaux d’endommagement et d’énergie de rupture. Lors de la deuxième étape ce modèle a été adapté au cas du fraisage de profil en avalant avec un angle d’hélice nul, où la matière susceptible d’être enlevée a une forme en demi lune, constant sur sa largeur, présente une épaisseur continûment variable et tendant vers zéro. Ce travail et les résultats obtenus permettent de distinguer la zone de coupe macroscopique de la zone microscopique à partir de l’épaisseur coupée. L’effet de taille bien connu en micromécanique a ainsi été retrouvé lors de ce passage macro-micro à travers l’influence de l’écrouissage due à la vitesse de déformation du matériau. Le phénomène bien connu expérimentalement de l’augmentation quasi exponentielle de l’énergie spécifique de coupe avec la diminution de l’épaisseur coupée a été étudié en relation avec les divers aspects de cet effet de taille. Pour faciliter l’exploitation et proposer un outil de compréhension physique de l’enlèvement de matière à la communauté scientifique et à l’industrie, dans une troisième étape, le modèle de comportement de « Johnson-Cook » modifié par une approche basée sur le second gradient de déformation a été développé dans ABAQUS®/EXPLICIT sous la forme d’un sous programme (ou sous-routine VUMAT). Finalement, au cours de la quatrième étape, l’application a été complètement développée pour simuler le fraisage de profil en avalant, de l’alliage d’Aluminium A2024-T351. En plus de l’effet de taille interne au copeau, les aspects dynamiques liés au comportement du système usinant ont été pris en compte à travers un modèle multi-échelle nommé « modèle dynamique hybride de coupe (HDC-modèle) » qui combine la rigidité équivalente d'une fraiseuse à grande vitesse (outil, porte-outil, broche, …) au niveau macroscopique avec la mécanique de formation de copeau au niveau mésoscopique. Cette application intégrant à la fois les effets d’échelles a pour but de fournir des données numériques sur la surface usinée qui puissent être comparées à des résultats expérimentaux. Malgré les difficultés de modélisation nous avons tenu à élaborer ce modèle complet car c’est bien la partie microscopique de la coupe en dynamique haute fréquence ou grande vitesse qui génère la surface usinée. Pour finir, des coupes expérimentales ont été exécutées en tournage et en fraisage pour valider les modèles proposés. Les résultats numériques sont ainsi comparés à ceux expérimentaux à chacune des étapes. De manière générale la concordance des résultats est bonne. Il faut cependant noter le grand nombre de paramètres des modèles numériques qui certains d’entre eux peuvent être des paramètres de recalage expérimental. Il apparaît donc que le caractère prédictif du modèle est limité essentiellement par les caractéristiques physiques de la matière usinée. On se retrouve dans la situation purement expérimentale des années 1970-80 qui a vu naître la notion de couple outil-matière (COM). L’approche d’aujourd’hui, à la fois expérimentale et numérique permet cependant de réduire fortement les coûts et de quantifier des phénomènes locaux très intéressants comme par exemple dans notre contribution : La propension à la segmentation et donc à la fragmentation dans certaines conditions de coupe, La longueur du contact copeau, face de coupe, l’amplitude des défauts de la surface usinée due à la dynamique globale

Full textModel-Based Software Engineering (MBSE) has been proposed as a promising software development methodology to overcome limitations of traditional programming-based methodology in dealing with the complexity of embedded systems. MBSE promotes the use of modeling languages for describing systems in an abstract way and provides means for automatically generating different development artifacts, e.g. code and documentation, from models. The development of a complex system often involves multiple stakeholders who use different tools to modify the development artifacts, model and code in particular in this thesis. Artifact modifications must be kept consistent: a synchronization process needs to propagate modifications made in one artifact to the other artifacts. In this study, the problem of synchronizing Unified Modeling Language (UML)-based architecture models, specified by UML composite structure (UML-CS) and UML state machine (UML-SM) elements, and object-oriented code is presented. UML-CSs are used for describing the component-based software architecture and UML-SMs for discrete event-driven behaviors of reactive systems. The first challenge is to enable a collaboration between software architects and programmers producing model and code by using different tools. This raises the synchronization problem of concurrent artifact modifications. In fact, there is a perception gap between diagram-based languages (modeling languages) and text-based languages (programming languages). On the one hand, programmers often prefer to use the more familiar combination of a programming language and an Integrated Development Environment. On the other hand, software architects, working at higher levels of abstraction, tend to favor the use of models, and therefore prefer diagram-based languages for describing the architecture of the system. The second challenge is that there is a significant abstraction gap between the model elements and the code elements: UML-CS andUML-SM elements are at higher level of abstraction than code elements. The gap makes current synchronization approaches hard to be applied since there is no easy way to reflect modifications in code back to model. This thesis proposes an automated synchronization approach that is composed of two main correlated contributions. To address the first challenge, a generic model-code synchronization methodological pattern is proposed. It consists of definitions of necessary functionalities and multiple processes that synchronize model and code based on several defined scenarios where the developers use different tools to modify model and code. This contribution is independent of UML-CSs and UML-SMs. The second contribution deals with the second challenge and is based on the results from the first contribution. In the second contribution, a bidirectional mapping is presented for reducing the abstraction gap between model and code. The mapping is a set of correspondences between model elements and code elements. It is used as main input of the generic model-code synchronization methodological pattern. More importantly, the usage of the mapping provides the functionalities defined in the first contribution and eases the synchronization of UML-CS and UML-SM elements and code. The approach is evaluated by means of multiple simulations and a case study

Full textNous avons caractérisé les interactions entre l'ADN et la surface de mica. Nous proposons un modèle simple pour décrire les interactions électrostatiques en solution entre l'ADN et le mica, en considérant le rôle des cations monovalents et divalents. La bonne corrélation avec les données expérimentales permet de valider un référentiel de conditions et une méthode d'adsorption réversible de l'ADN sur mica prétraité nickel. Nous avons parallèlement développé un système de plots pour ancrer l'ADN par ses extrémités.
Le contrôle de ces méthodologies permet de caractériser l'accessibilité en fonction des états d'adsorption. Nous abordons cette problématique en caractérisant l'activité de la bléomycine sur l'ADN. Cette approche sur un système modèle permet de caractériser l'influence de la surface en termes d'accessibilité et d'activité.
La dernière partie de ce travail considère la caractérisation des interactions de la protéine Ku avec l'ADN dans le cadre de l'étude de la réparation des cassures double brin.

Full textModel-based systems engineering methodologies such as Simulation, Formal Methods (FM) and Enactment have been used extensively in recent decades to study, analyze, and forecast the properties and behaviors of complex systems. The results of these analyses often reveal subtle knowledge that could enhance deeper understanding of an existing system or provide timely feedbacks into a design process to avert costly (and catastrophic) errors that may arise in the system. Questions about different aspects of a system are usually best answered using some specific analysis methodologies; for instance, system's performance and behavior in some specified experimental frames can be efficiently studied using appropriate simulation methodologies. Similarly, verification of properties such as, liveness, safeness and fairness are better studied with appropriate formal methods while enactment methodologies may be used to verify assumptions about some time-based and human-in-the-loop activities and behaviors. Therefore, an exhaustive study of a complex (or even seemingly simple) system often requires the use of different analysis methodologies to produce complementary answers to likely questions. There is no gainsaying that a combination of multiple analysis methodologies offers more powerful capabilities and rigor to test system designs than can be accomplished with any of the methodologies applied alone. While this exercise will provide (near) complete knowledge of complex systems and helps analysts to make reliable assumptions and forecasts about their properties, its practical adoption is not commensurate with the theoretical advancements, and evolving formalisms and algorithms, resulting from decades of research by practitioners of the different methodologies. This shortfall has been linked to the prerequisite mathematical skills for dealing with most formalisms, which is compounded by little portability of models between tools of different methodologies that makes it mostly necessary to bear the herculean task of creating and managing several models of same system in different formalisms. Another contributing factor is that most of existing computational analysis environments are dedicated to specific analysis methodologies (i.e., simulation or FM or enactment) and are usually difficult to extend to accommodate other approaches. Thus, one must learn all the formalisms underlining the various methods to create models and go round to update all of them whenever certain system variables change. The contribution of this thesis to alleviating the burdens on users of multiple analysis methodologies for exhaustive study of complex systems can be described as a framework that uses Model-Driven Engineering (MDE) technologies to federate simulation, FM and enactment analysis methodologies behind a unified high-level specification language with support for automated synthesis of artifacts required by the disparate methodologies. This framework envelops four pieces of contributions: i) a methodology that emulates the Model- Driven Architecture (MDA) to propose an independent formalism to integrate the different analysis methodologies. ii) Integration of concepts from the three methodologies to provide a common metamodel to unite some selected formalisms for simulation, FM and enactment. Iii) Mapping rules for automated synthesis of artifacts for simulation, FM and enactment from a common reference model of a system and its requirements. iv) A framework for the enactment of idiscrete event systems. We use the beverage vending system as a running example throughout the thesis. (...)

Full textIn this work, methodologies to evaluate the wear of flexible riser pipe and bend stiffener samples were developed. In order to achieve this goal, a three coordinate measuring machine (3CMM) was used to evaluate the wear rates of samples tested in in a large-scale tribometer. Additionally, the events that occur during the sliding wear of these samples were correlated with vibration signals from the tribometer structure. The first methodology was applied to estimate the linear wear of riser samples of the polyamide outer coating that was based on the thickness reduction during the test. The second methodology was designed to estimate the volumetric wear loss of the bendstiffener samples. To evaluate the thickness loss of the riser samples, the Calypso® software was used to define the alignment and to determine and execute the measurement strategy. In order to assess the bend-stiffener volume, the same software was used to define the system alignment. The Dimension Volume® software was used to define and to perform the measurement strategy. The sample volume was calculated using a specially designed program that was developed in Matlab®. In order to analyze the vibrations during the wear test, a routine of data acquisition, monitoring and storage of vibration signals in Labview® software was developed and implemented. The results showed that the developed methodology to quantify the riser thickness loss using a 3CMM is viable and efficient in measuring the wear process of this tribosystem. It was also found that the developed program using Matlab® was an effective tool to evaluate the volumetric losses of bend-stiffeners samples. The measurement strategy using a mesh spacing of 1 mm x 1 mm was considered the most adequate to estimate the volume of a bend-stiffener sample accurately and with the least possible amount of points. Furthermore, it was observed a vibration peak located at 16.71 Hz, that should be related to the wear process.

Tais amostras foram testadas em um tribômetro capaz de realizar ensaios de desgaste por deslizamento em escala real. Adicionalmente, foram correlacionados os eventos que ocorrem durante o processo de desgaste destas amostras com as vibrações na estrutura do tribômetro. A primeira metodologia foi aplicada na estimativa do desgaste linear em amostras de risers, com base na variação de espessura, enquanto que a segunda foi destinada à estimativa do desgaste volumétrico em amostras de enrijecedores, tendo por base a perda de volume das mesmas. Para avaliar a perda de espessura nas amostras de riser foi utilizado o software Calypso® na definição do alinhamento e na determinação e execução da estratégia de medição. Já na avaliação do volume das amostras de enrijecedores, foi utilizado o mesmo software na definição do alinhamento. O software Dimension Volume® foi empregado na definição e execução da estratégia de medição, e, para calcular o volume destas amostras, foi elaborado e utilizado um programa em Matlab®. Com o intuito de analisar as vibrações durante o ensaio de desgaste, foi desenvolvida e implementada uma rotina de aquisição, monitoramento e salvamento dos sinais de vibrações no software Labview®. Os resultados obtidos permitiram concluir que a metodologia desenvolvida para quantificação da perda de espessura de risers usando uma MM3C é uma técnica viável e eficiente. Constatou-se, também, que o programa desenvolvido em Matlab® foi uma ferramenta eficaz na avaliação volumétrica das amostras de enrijecedores. A estratégia de medição com malha 1 mm x 1 mm foi considerada a mais adequada para estimar o volume de uma amostra de enrijecedor, com precisão e com a menor quantidade de pontos possível. Além disso, verificou-se que o pico da amplitude vibratória esteve localizado em 16,71 Hz, que deve estar relacionado ao processo de desgaste.
