This book was released on 1999 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce rapport détaille la problématique du couplage entre modèles de dimension infinie (ou à paramètres distribués) et modèles de dimension finie (ou à paramètres localisés). Dans les deux cas, les modèles étudiés sont fondés sur l'analyse des processus de stockage, de dissipation et de transfert d'énergie. Les modèles à paramètres localisés considérés sont des bond graphs. Le premier chapitre s'attache à décrire de manière formelle le processus de modélisation récursive. Cette approche montre qu'aucune hypothèse physique ne s'oppose formellement à la généralisation des éléments constitutifs des bond graphs. Les éléments ainsi généralisés sont définis par des opérateurs liant les efforts et les flux à leurs accès et sont baptisés éléments fonctionnels. De nombreux exemples d'éléments fonctionnels sont passés en revue afin d'illustrer l'intérêt de la problématique de couplage. Le deuxième chapitre aborde le problème de la réduction d'opérateurs linéaires de dimension infinie à des systèmes de dimension finie réalisés par bond graph. La méthode développée fait usage des approximants de Padé pour la réduction proprement dite, puis des propriétés des séries de Stieltjes pour établir le caractère physiquement admissible de leur réalisation. Cette méthode s'applique aux opérateurs de relaxation (et donc notamment à des modèles d'impédance hydraulique fractale pour lesquels elle est étudiée en détail). Le troisième chapitre s'attaque au problème de la généralisation de la notion de passivité aux systèmes linéaires de dimension infinie. La caractérisation de cette propriété, comme dans le cas de dimension finie, conduit à la notion de fonction de transfert positive réelle, et définit ainsi la plus large famille de système linéaire pour lesquels les méthodes de réduction similaire à celle du chapitre 2 peuvent avoir un sens. Enfin, en annexe 2, sont développés quelques résultats préliminaires concernant la réduction d'opérateurs non linéaires à mémoire évanescente. Ceux-ci ouvrent la voie à la généralisation ultérieure de ce travail aux éléments fonctionnels non linéaires.

Download or read book An Introduction to Bond Graph Modeling with Applications written by J. A. Tenreiro Machado and published by CRC Press. This book was released on 2021-06-18 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Bond Graph Modeling with Applications presents a collection of exercises on dynamical systems, modeling and control for university students in the areas of engineering, physics and applied mathematics. We can find several books on bond graphs, but most merely a small set of exercises and, in a few cases, some commands for computer packages like MATLAB or Mathematica. It is difficult to find books with a broad set of solved exercises and proposed exercises with solutions, guiding researchers starting their work with bond graphs, or students who are just beginning their study of the topic. This book aims to fill that gap, and provide a comprehensive, reader-friendly introduction to the Bond Graph modeling tool. Features Gives in-depth theoretical background coupled with practical, hands-on instructions. Provides a clear pedagogical framework, with numerous exercises and problems. Suitable for students and researchers who work with bond graphs: principally such as applied mathematicians, physicist and engineers.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book discusses the eroding economics of nuclear power for electricity generation as well as technical, legal, and political acceptance issues. The use of nuclear power for electricity generation is still a heavily disputed issue. Aside from technical risks, safety issues, and the unsolved problem of nuclear waste disposal, the economic performance is currently a major barrier. In recent years, the costs have skyrocketed especially in the European countries and North America. At the same time, the costs of alternatives such as photovoltaics and wind power have significantly decreased. Contents History and Current Status of the World Nuclear Industry The Dramatic Decrease of the Economics of Nuclear Power Nuclear Policy in the EU The Legacy of Csernobyl and Fukushima Nuclear Waste and Decommissioning of Nuclear Power Plants Alternatives: Heading Towards Sustainable Electricity Systems Target Groups Researchers and students in the fields of political, economic and technical sciences Energy (policy) experts, nuclear energy experts and practitioners, economists, engineers, consultants, civil society organizations The Editors Prof. Dr. Reinhard Haas is University Professor of energy economics at the Institute of Energy Systems and Electric Drives at Technische Universität Wien, Austria.

Download or read book Functional Integration written by Cécile Dewitt-Morette and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The program of the Institute covered several aspects of functional integration -from a robust mathematical foundation to many applications, heuristic and rigorous, in mathematics, physics, and chemistry. It included analytic and numerical computational techniques. One of the goals was to encourage cross-fertilization between these various aspects and disciplines. The first week was focused on quantum and classical systems with a finite number of degrees of freedom; the second week on field theories. During the first week the basic course, given by P. Cartier, was a presentation of a recent rigorous approach to functional integration which does not resort to discretization, nor to analytic continuation. It provides a definition of functional integrals simpler and more powerful than the original ones. Could this approach accommodate the works presented by the other lecturers? Although much remains to be done before answering "Yes," there seems to be no major obstacle along the road. The other courses taught during the first week presented: a) a solid introduction to functional numerical techniques (A. Sokal) and their applications to functional integrals encountered in chemistry (N. Makri). b) integrals based on Poisson processes and their applications to wave propagation (S. K. Foong), in particular a wave-restorer or wave-designer algorithm yielding the initial wave profile when one can only observe its distortion through a dissipative medium. c) the formulation of a quantum equivalence principle (H. Kleinert) which. given the flat space theory, yields a well-defined quantum theory in spaces with curvature and torsion.

Download or read book Physics on Manifolds written by M. Flato and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the Colloquium "Analysis, Manifolds and Physics" organized in honour of Yvonne Choquet-Bruhat by her friends, collaborators and former students, on June 3, 4 and 5, 1992 in Paris. Its title accurately reflects the domains to which Yvonne Choquet-Bruhat has made essential contributions. Since the rise of General Relativity, the geometry of Manifolds has become a non-trivial part of space-time physics. At the same time, Functional Analysis has been of enormous importance in Quantum Mechanics, and Quantum Field Theory. Its role becomes decisive when one considers the global behaviour of solutions of differential systems on manifolds. In this sense, General Relativity is an exceptional theory in which the solutions of a highly non-linear system of partial differential equations define by themselves the very manifold on which they are supposed to exist. This is why a solution of Einstein's equations cannot be physically interpreted before its global behaviour is known, taking into account the entire hypothetical underlying manifold. In her youth, Yvonne Choquet-Bruhat contributed in a spectacular way to this domain stretching between physics and mathematics, when she gave the proof of the existence of solutions to Einstein's equations on differential manifolds of a quite general type. The methods she created have been worked out by the French school of mathematics, principally by Jean Leray. Her first proof of the local existence and uniqueness of solutions of Einstein's equations inspired Jean Leray's theory of general hyperbolic systems.

Download or read book Thoughts on grammaticalization written by Christian Lehmann and published by BoD – Books on Demand. This book was released on 2024-05-23 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Thoughts on grammaticalization" was first published in a working-paper version in 1982 and became very influential immediately, even though it was properly published only in 1995. Despite its modest title, the book can be read as an advanced introduction to grammaticalization, though its conception is very original. The present edition contains a number of corrections of the 1995 edition. After a short review of the history of research, the work introduces and delimits the concepts related to grammaticalization. It then provides extensive exemplification of grammaticalization phenomena in diverse languages, ordered by grammatical domains such as the verbal, pronominal and nominal sphere and clause level relations. The final chapter presents a theory of grammaticalization which is based on the autonomy of the linguistic sign with respect to the paradigmatic and syntagmatic axes. This is the basis of the structural parameters that constitute grammaticalization. They are operationalized to the point of rendering degrees of grammaticalization measurable.

Download or read book Biosocialities Genetics and the Social Sciences written by Sahra Gibbon and published by Routledge. This book was released on 2007-07-20 with total page 387 pages. 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.
