La premi re m thode d velopp e s'appuie sur les propri t s g om triques des champs de vecteurs.

Ce cycle d finit la r gion finale atteindre par le syst me depuis son tat initial, par une trajectoire d termin e de mani re optimale selon un crit re. La m thode propos e est appliqu e aux convertisseurs d' nergie Buck et Buck-Boost alimentant une charge r sistive. Une extension IRn a t propos e et d montr e. Elle est illustr e sur un syst me non-lin aire dans IR3. La deuxi me m thode est d velopp e dans IR2 et bas e sur la th orie de Lyapunov. Il s'agit de d terminer par une approche g om trique, une fonction de Lyapunov quadratique commune aux deux modes de fonctionnement du syst me, qui permette d'obtenir un cycle limite hybride stable le plus proche possible du point de fonctionnement d sir et une commande stabilisante directe des interrupteurs.

Available in PDF, EPUB and Kindle. Book excerpt: Ce mémoire de thèse présente deux nouvelles approches pour l'analyse et la commande des systèmes non-linéaires complexes, comme les systèmes dynamiques à commutation de la classe des convertisseurs d'énergie électrique. Ces systèmes ont plusieurs modes de fonctionnement et ont un point de fonctionnement désiré qui, en général, n'est le point d'équilibre d'aucun des modes. Dans cette classe de systèmes, la commutation d'un mode de fonctionnement à un autre est commandée selon une loi qui doit être synthétisée. Par conséquent, la synthèse de commande implique l'étude des conditions qui permettent à un cycle limite stable de s'établir au voisinage du point de fonctionnement désiré, puis de la trajectoire de commande qui permet de l'atteindre en respectant les contraintes physiques de comportement (courant maximum supporté par les composants,. . .) ou les contraintes de temps (durée minimum entre deux commutations,. . .). Le cycle limite sera qualifié d'hybride car il est composé de plusieurs dynamiques(deux dans ces travaux).La première méthode développée s'appuie sur les propriétés géométriques des champs de vecteurs et est une extension d'une partie des travaux de thèse de Manon au LAGEP. Une condition nécessaire et suffisante d'existence et de stabilité d'un cycle limite hybride composé d'une séquence de deux modes de fonctionnement dans IR2 est présentée. Ce cycle définit la région finale à atteindre par le système depuis son état initial, par une trajectoire déterminée de manière optimale selon un critère donné (durée totale, énergie dépensée, . . .). La méthode proposée est appliquée aux convertisseurs d'énergie Buck et Buck-Boost alimentant une charge résistive. Une extension à IRn a été proposée et démontrée. Elle est illustrée sur un système non-linéaire dans IR3.La deuxième méthode est développée dans IR2 et basée sur la théorie de Lyapunov, bien connue en automatique pour étudier la stabilité des systèmes non-linéaires et concevoir des commandes stabilisantes.Il s'agit de déterminer par une approche géométrique, une fonction de Lyapunov quadratique commune aux deux modes de fonctionnement du système, qui permette d'obtenir un cycle limite hybride stable le plus proche possible du point de fonctionnement désiré et une commande stabilisante directe des interrupteurs.

It is and begin with the answers. Then one day, that they can't see the problem. perhaps you will find the final question. O. K. Chesterton. The Scandal of Father 'The Hermit Qad in Crane Feathers' in R. Brown 'The point of a Pin'. van Gu!ik's The Chinese Maze Murders. Growing specialization and diversification have brought a host of monographs and textbooks on increasingly specialized topics. However, the "tree" of knowledge of mathematics and related fields does not grow only by putting forth new branches. It also happens, quite often in fact, that branches which were thought to be completely disparate are suddenly seen to be related. Further, the kind and level of sophistication of mathematics applied in various sciences has changed drastically in recent years: measure theory is used (non-trivially) in regional and theoretical economics; algebraic geometry interacts with physics; the Minkowsky lemma, coding theory and the structure of water meet one another in packing and covering theory; quantum fields, crystal defects and mathematical programming profit from homotopy theory; Lie algebras are relevant to filtering; and prediction and electrical engineering can use Stein spaces. And in addition to this there are such new emerging subdisciplines as "experimental mathematics", "CFD", "completely integrable systems", "chaos, synergetics and large-scale order", which are almost impossible to fit into the existing classification schemes. They draw upon widely different sections of mathematics.

Book excerpt: Noncommutative Geometry is one of the most deep and vital research subjects of present-day Mathematics. Its development, mainly due to Alain Connes, is providing an increasing number of applications and deeper insights for instance in Foliations, K-Theory, Index Theory, Number Theory but also in Quantum Physics of elementary particles. The purpose of the Summer School in Martina Franca was to offer a fresh invitation to the subject and closely related topics; the contributions in this volume include the four main lectures, cover advanced developments and are delivered by prominent specialists.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents a view on grammaticalisation radically different from standard views centering around the cline of grammaticality. Grammar is seen as a complex sign system, and, as a consequence, grammatical change always comprises semantic change. What unites morphology, topology (word order), constructional syntax and other grammatical subsystems is their paradigmatic organisation. The traditional concept of an inflexional paradigm is generalised as the structuring principle of grammar. Grammatical change involves paradigmatic restructuring, and in the process of grammatical change morphological, topological and constructional paradigms often connect to form complex paradigms. The book introduces the concept of connecting grammaticalisation to describe the formation, restructuring and dismantling of such complex paradigms. Drawing primarily on data from Germanic, Romance and Slavic languages, the book offers both a broad general discussion of theoretical issues (part one) and three case studies (part two).

This book was released on 2021-04-30 with total page 830 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the proceedings of the 21st Congress of the International Ergonomics Association (IEA 2021), held online on June 13-18, 2021. By highlighting the latest theories and models, as well as cutting-edge technologies and applications, and by combining findings from a range of disciplines including engineering, design, robotics, healthcare, management, computer science, human biology and behavioral science, it provides researchers and practitioners alike with a comprehensive, timely guide on human factors and ergonomics. It also offers an excellent source of innovative ideas to stimulate future discussions and developments aimed at applying knowledge and techniques to optimize system performance, while at the same time promoting the health, safety and wellbeing of individuals. The proceedings include papers from researchers and practitioners, scientists and physicians, institutional leaders, managers and policy makers that contribute to constructing the Human Factors and Ergonomics approach across a variety of methodologies, domains and productive sectors. This volume includes papers addressing the following topics: Activity Theories for Work Analysis and Design (ATWAD), Organisation design and management (ODAM), Ergonomic Work Analysis and Training (EWAT), Systems HF/E, HF/E Education and Professional Certification Development.
