Book Synopsis Systèmes dynamiques et incertitudes by : Franziska Schmidt

Book excerpt: Les structures de génie civil présentent souvent des incertitudes, qui peuvent être de différentes origines et de différentes formes. Nous abordons dans cette thèse quelques aspects de ces incertitudes. Tout d’abord, nous étudions l’influence de conditions initiales et de paramètres incertains dans les mouvements non réguliers. Ceci passe par la définition d’une matrice de variation tangente. Cette étude est appliquée à quelques cas particuliers, dont la chute de blocs le long d’une pente et un oscillateur linéaire à impacts. Ensuite, l’impact d’une sollicitation incertaine sous forme de bruit blanc est étudié à l’aide de l’équation de Fokker-Planck. Celle-ci est résolue de façon numérique avec la méthode des différences finies afin d’obtenir la densité de probabilité des états du système. En particulier, cela est réalisé pour les oscillateurs linéaire, de Duffing, avec friction et le système dynamique du pompage énergétique. Une troisième partie se consacre à l’étude des exposants de Lyapunov. Dans un premier temps, nous les étudions en temps fini. En effet, ils dépendent alors du temps, des conditions initiales, de l’espace, de la divergence initiale... et ils peuvent alors être différents de leur valeur à l’infini. Ensuite, nous testons une méthode innovante pour calculer ces exposants, en utilisant la matrice de divergence. Elle est appliquée à divers systèmes dynamiques, ce qui permet d’évaluer son efficacité. Finalement, l’incertitude sur la loi de comportement est étudiée pour le système dynamique du pompage énergétique. Diverses lois de comportement, élastiques, élastoplastiques parfaits et élastoplastiques avec endommagement, sont appliquées et la robustesse du phénomène de transfert d’énergie est estimée.

This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur le calcul d'une sur-approximation conservative pour les solutions d'équations différentielles ordinaires en présence d'incertitudes et sur son application à l'estimation et l'analyse de systèmes dynamiques à temps continu. L'avantage principal des méthodes et des algorithmes de calculs présentés dans cette thèse est qu'ils apportent une preuve numérique de résultats. Cette thèse est organisée en deux parties. La première partie est consacrée aux outils mathématiques et aux méthodes d'intégration numérique garantie des équations diff érentielles incertaines. Ces méthodes permettent de caractériser de manière garantie l'ensemble des trajectoires d'état engendrées par un système dynamique incertain dont les incertitudes sont naturellement représentées par des intervalles bornés. Dans cette optique, nous avons développé une méthode d'intégration hybride qui donne de meilleurs résultats que les méthodes d'intégration basées sur les modèles de Taylor intervalles. La seconde partie aborde les problèmes de l'identification et de l'observation dans un contexte à erreurs bornées ainsi que le problème d'atteignabilité continue pour la véri cation de propriétés des systèmes dynamiques hybrides.

Book Synopsis Finite Volumes for Complex Applications IX - Methods, Theoretical Aspects, Examples by : Robert Klöfkorn
Download or read book Finite Volumes for Complex Applications IX - Methods, Theoretical Aspects, Examples written by Robert Klöfkorn and published by Springer Nature. This book was released on 2020-06-09 with total page 727 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings of the 9th conference on "Finite Volumes for Complex Applications" (Bergen, June 2020) are structured in two volumes. The first volume collects the focused invited papers, as well as the reviewed contributions from internationally leading researchers in the field of analysis of finite volume and related methods. Topics covered include convergence and stability analysis, as well as investigations of these methods from the point of view of compatibility with physical principles. Altogether, a rather comprehensive overview is given on the state of the art in the field. The properties of the methods considered in the conference give them distinguished advantages for a number of applications. These include fluid dynamics, magnetohydrodynamics, structural analysis, nuclear physics, semiconductor theory, carbon capture utilization and storage, geothermal energy and further topics. The second volume covers reviewed contributions reporting successful applications of finite volume and related methods in these fields. The finite volume method in its various forms is a space discretization technique for partial differential equations based on the fundamental physical principle of conservation. Many finite volume methods preserve further qualitative or asymptotic properties, including maximum principles, dissipativity, monotone decay of free energy, and asymptotic stability, making the finite volume methods compatible discretization methods, which preserve qualitative properties of continuous problems at the discrete level. This structural approach to the discretization of partial differential equations becomes particularly important for multiphysics and multiscale applications. The book is a valuable resource for researchers, PhD and master’s level students in numerical analysis, scientific computing and related fields such as partial differential equations, as well as engineers working in numerical modeling and simulations.

Book Synopsis Fluorine Magnetic Resonance Imaging by : Ulrich Flogel
Download or read book Fluorine Magnetic Resonance Imaging written by Ulrich Flogel and published by CRC Press. This book was released on 2016-10-26 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, fluorine (19F) magnetic resonance imaging (MRI) has garnered significant scientific interest in the biomedical research community owing to the unique properties of fluorinated materials and the 19F nucleus. Fluorine has an intrinsically sensitive nucleus for MRI. There is negligible endogenous 19F in the body and thus there is no background signal. Fluorine-containing compounds are ideal tracer labels for a wide variety of MRI applications. Moreover, the chemical shift and nuclear relaxation rate can be made responsive to physiology via creative molecular design. This book is an interdisciplinary compendium that details cutting-edge science and medical research in the emerging field of 19F MRI. Edited by Ulrich Flögel and Eric Ahrens, two prominent MRI researchers, this book will appeal to investigators involved in MRI, biomedicine, immunology, pharmacology, probe chemistry, and imaging physics.
Book Synopsis Chaotic Evolution and Strange Attractors by : David Ruelle
Download or read book Chaotic Evolution and Strange Attractors written by David Ruelle and published by Cambridge University Press. This book was released on 1989-09-07 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, based on lectures given at the Accademia dei Lincei, is an accessible and leisurely account of systems that display a chaotic time evolution. This behaviour, though deterministic, has features more characteristic of stochastic systems. The analysis here is based on a statistical technique known as time series analysis and so avoids complex mathematics, yet provides a good understanding of the fundamentals. Professor Ruelle is one of the world's authorities on chaos and dynamical systems and his account here will be welcomed by scientists in physics, engineering, biology, chemistry and economics who encounter nonlinear systems in their research.
Book Synopsis Amongst Mathematicians by : Elena Nardi
Download or read book Amongst Mathematicians written by Elena Nardi and published by Springer Science & Business Media. This book was released on 2008 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a unique perspective on ways in which mathematicians: perceive their students' learning; teach; reflect on their teaching practice. Elena Nardi achieves this by employing two fictional, yet entirely data-grounded, characters to create a conversation on these important issues. The construction of these characters is based on large bodies of data including intense focused group interviews with mathematicians and extensive analyses of students' written work, collected and analyzed over a substantial period.
