Dans ce cadre, nous nous intéressons à une sous-classe de SDH couplant explicitement des configurations discrètes et des équations algébro-différentielles dont la commande est événementielle et périodique. On trouve ce type de fonctionnement dans le cadre de procédés batch et de systèmes électrotechniques. Les travaux menés dans cette thèse ont pour objet d'étudier les convertisseurs statiques sous un aspect hybride, de manière à caractériser ses cycles de fonctionnement lorsque la commande est périodique. L'étude a conduit à examiner le problème selon deux aspects complémentaires que sont l'analyse et la synthèse. L'analyse doit permettre de déterminer la période du cycle de fonctionnement du convertisseur en connaissant a priori la période de la commande et les conditions initiales appliquées au convertisseur. La synthèse consiste à déterminer les caractéristiques de la commande quand le cycle de fonctionnement du convertisseur est imposé. Cette problématique a conduit dans un premier temps au développement d'une modélisation graphique à base de RdP hybrides qui a permis de caractériser des systèmes électrotechniques simples. Cependant cette approche ne s'applique qu'à certains types de convertisseurs car les RdP Hybrides sont limités à l'utilisation de variables d'état qui sont linéaires. Nous avons par conséquent orienté nos travaux vers une modélisation par Réseaux de Petri Mixtes. Afin de conserver tous les avantages de ce modèle et lui associer un cadre formel pour l'analyse et la synthèse

Book excerpt: In recent years, there has been a growing debate, particularly in the UK and Europe, over the merits of using discrete-event simulation (DES) and system dynamics (SD); there are now instances where both methodologies were employed on the same problem. This book details each method, comparing each in terms of both theory and their application to various problem situations. It also provides a seamless treatment of various topics--theory, philosophy, detailed mechanics, practical implementation--providing a systematic treatment of the methodologies of DES and SD, which previously have been treated separately.

Available in PDF, EPUB and Kindle. Book excerpt: Biosocialities, Genetics and the Social Sciences explores the social, cultural and economic transformations that result from innovations in genomic knowledge and technology. This pioneering collection uses Paul Rabinow’s concept of biosociality to chart the shifts in social relations and ideas about nature, biology and identity brought about by developments in biomedicine. Based on new empirical research, it contains chapters on genomic research into embryonic stem cell therapy, breast cancer, autism, Parkinson’s and IVF treatment, as well as on the expectations and education surrounding genomic research. It covers four main themes: novel modes of identity and identification, such as genetic citizenship the role of institutions, ranging from disease advocacy organizations and voluntary organizations to the state the production of biological knowledge, novel life-forms, and technologies the generation of wealth and commercial interests in biology. Including an afterword by Paul Rabinow and case studies on the UK, US, Canada, Germany, India and Israel, this book is key reading for students and researchers of the new genetics and the social sciences – particularly medical sociologists, medical anthropologists and those involved with science and technology studies.

This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally accepted that photosynthesis, whereby solar is transformed into geobiochemical energy, is one of the most important processes in the bio sphere. When we realize that the human population, most of which is starving, wi I I double in 20-30 years, and that photosynthesis is in practice the only source (direct or indirect) of food not only for men, but for al I I iving beings, its im portance becomes even plainer. This fact was recognized from the outset of the International Biological Programme, when photosynthesis was selected as one of the principal problems to be concentrated on. The significance of the IBP in initiating a broader-based ap proach and worldwide collaboration need not be emphasized here; it is merely ne cessary to consider the rapid increase in the number of papers on photosynthesis since its inception. It is of fundamental importance for scientists working on photosynthesis to get information on what has been done in recent years in this discipl ine. Thus as complete as possible a bibl iography is badly needed. The complexity of this pro blem requires also that the progress of ecology, chemistry and physics, as far as they concern photosynthesis, be fol lowed. Such a bib I iography, covering at least the last ten years, wi I I be indispensable for final synthesis of the results of the IBP photosynthetic programme.

Book excerpt: An unflinching look at the aspiring city-builders of our smart, mobile, connected future. From Beijing to Boston, cities are deploying smart technology—sensors embedded in streets and subways, Wi-Fi broadcast airports and green spaces—to address the basic challenges faced by massive, interconnected metropolitan centers. In Smart Cities, Anthony M. Townsend documents this emerging futuristic landscape while considering the motivations, aspirations, and shortcomings of the key actors—entrepreneurs, mayors, philanthropists, and software developers—at work in shaping the new urban frontier.

Available in PDF, EPUB and Kindle. Book excerpt: "Developmental work research is an innovative approach to the study and reshaping of work and learning. It expands cultural-historical activity theory by bringing it to the domains of work, technology and organizations. The world of work is in turmoil, increasingly dominated by 'runaway objects' generated by globalization and greed (global markets are such massive objects out of control). Yet it is the object that motivates work and generates visons of better future. The use values of objects have not vanished, although they are more difficult to grasp than perhaps ever before. Developmental work research rediscovers and expands use values in runaway objects. In workplace interventions it engages practitioners in expansive re-forging of the objects of their work."--Cover.

This book was released on 1981-01-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume seeks to contribute to an interdisciplinary, comparative, and historical study of Western welfare states. It attempts to link their historical dynamics and contemporary problems in an international perspective. Building on collaboration between European-and American-based research groups, the editors have coordinated contributions by economists, political scientists, sociologists, and historians. The developments they analyze cover a time span from the initiation of modern national social policies at the end of the nineteenth century to the present. The experiences of all the presently existing Western European systems except Spain and Portugal are systematically encompassed, with comparisons developed selectively with the experiences of the United States and Canada. The development of the social security systems, of public expenditures!and taxation, of public education and educational opportunities, and of income inequality are described, compared, and analyzed for varying groupings of the Western European and North American nations. This volume addresses itself mainly to two audiences. The first includes all students of policy problems of the welfare states who seek to gain a comparative perspective and historical understanding. A second group may be more interested in the theory and empirical analysis of long-term societal developments. In this context, the growth of the welfare states ranges as a major departure, along with the development of national states and capitalist economies. The welfare state is interpreted as a general phenomenon of modernization, as a product of the increasing differentiation and the growing size of societies on the one hand, and of processes of social and political mobilization on the other. It is an important element of the structural convergence of modern societies -- by its mere weight in all countries -- and at the same time a source of divergence by the variations within its institutional structure.

Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.
