Systèmes dynamiques discrets non réguliers déterministes ou stochastiques : applications aux modèles avec frottement ou impact
Author: BASTIEN JérômePublisher: Lavoisier
ISBN: 2746289083
Category :
Languages : en
Pages : 546
Book Description
Cet ouvrage présente différents modèles discrets en dynamique pour la modélisation de phénomènes mécaniques non linéaires liés au frottement ou à l’impact. Les sollicitations sont exposées dans un cadre déterministe et stochastique. Pour ce dernier, le cas de variétés de configuration euclidienne ou riemannienne est abordé. La difficulté réside dans le type d’équations différentielles non linéaires particulières utilisées. Le cadre théorique ainsi que des schémas numériques sont détaillés pour chaque équation. Trois types de problèmes sont d’abord étudiés dans le cas particulier d’un solide à un degré de liberté : la force de frottement, la loi d’impact en déterministe et le frottement dans un cadre stochastique. Ensuite, de nombreux exemples sont commentés et fournissent, dans un cadre théorique ou applicatif, de nombreux modèles accompagnés de leurs schémas numériques. Des rappels théoriques fondamentaux sont proposés ainsi que deux preuves complètes de convergence de schémas numériques dans le cas du frottement déterministe ou stochastique.
Language in Complexity

Pages : 218
Book Description
This contributed volume explores the achievements gained and the remaining puzzling questions by applying dynamical systems theory to the linguistic inquiry. In particular, the book is divided into three parts, each one addressing one of the following topics: 1) Facing complexity in the right way: mathematics and complexity 2) Complexity and theory of language 3) From empirical observation to formal models: investigation of specific linguistic phenomena, like enunciation, deixis, or the meaning of the metaphorical phrases The application of complexity theory to describe cognitive phenomena is a recent and very promising trend in cognitive science. At the time when dynamical approaches triggered a paradigm shift in cognitive science some decade ago, the major topic of research were the challenges imposed by classical computational approaches dealing with the explanation of cognitive phenomena like consciousness, decision making and language. The target audience primarily comprises researchers and experts in the field but the book may also be beneficial for graduate and post-graduate students who want to enter the field.
The Foundations of Mechanics and Thermodynamics

Book Description
German scholars, against odds now not only forgotten but also hard to imagine, were striving to revivify the life of the mind which the mental and physical barbarity preached and practised by the -isms and -acies of 1933-1946 had all but eradicated. Thinking that among the disciples of these elders, restorers rather than progressives, I might find a student or two who would wish to master new mathematics but grasp it and use it with the wholeness of earlier times, in 1952 I wrote to Mr. HAMEL, one of the few then remaining mathematicians from the classical mould, to ask him to name some young men fit to study for the doc torate in The Graduate Institute for Applied Mathematics at Indiana University, flourishing at that time though soon to be destroyed by the jealous ambition of the local, stereotyped pure. Having just retired from the Technische Universitat in Charlottenburg, he passed my inquiry on to Mr. SZABO, in whose institute there NOLL was then an assistant. Although Mr.

Book Description
0.1 Gaps in Optimizing A comparison of the levels of development of Operations Research, Simulation Technique and Optimal Control Theory appears to gain increasing interest. Operations Research Sciences achieved very high mathematical standards and solved a great amount of important optimization problems, mainly at the level of management of private corporation and civil or military government tasks, however, these achievements are seldom incorporated in the mathematical curriculum of modern universities. Nevertheless, Operations Research seems to have failed in solving long range or strategical problems as they arise in any broader social, economical or political context (MUller-Merbach, 1976). Also for the weakest task, namely that of improving theory building, system simulation works as an optimization tool. Simulation models of large complex systems, like socio economical or political ones, failed until now to fit large empirical data bases. This was, in fact, one of the few serious objections against the form in which Forrester solved some problems modelling and simulating urban and world de velopments (Forrester, 1969; Forrester, 1971; IEEE-SCC October 197o; IEEE-SMC April 1972; Mass, 1974; Schroeder, 1975).
Adaptive Control
Author: Ioan Doré LandauPublisher: Springer Science & Business Media
ISBN: 0857296647
Category : Technology & Engineering
Languages : en
Pages : 595
Book Description
Adaptive Control (second edition) shows how a desired level of system performance can be maintained automatically and in real time, even when process or disturbance parameters are unknown and variable. It is a coherent exposition of the many aspects of this field, setting out the problems to be addressed and moving on to solutions, their practical significance and their application. Discrete-time aspects of adaptive control are emphasized to reflect the importance of digital computers in the application of the ideas presented. The second edition is thoroughly revised to throw light on recent developments in theory and applications with new chapters on: multimodel adaptive control with switching, direct and indirect adaptive regulation and adaptive feedforward disturbance compensation. Many algorithms are newly presented in MATLAB® m-file format to facilitate their employment in real systems. Classroom-tested slides for instructors to use in teaching this material are also now provided. All of this supplementary electronic material can be downloaded from fill in URL. The core material is also up-dated and re-edited to keep its perspective in line with modern ideas and more closely to associate algorithms with their applications giving the reader a solid grounding in: synthesis and analysis of parameter adaptation algorithms, recursive plant model identification in open and closed loop, robust digital control for adaptive control; • robust parameter adaptation algorithms, practical considerations and applications, including flexible transmission systems, active vibration control and broadband disturbance rejection and a supplementary introduction on hot dip galvanizing and a phosphate drying furnace. Control researchers and applied mathematicians will find Adaptive Control of significant and enduring interest and its use of example and application will appeal to practitioners working with unknown- and variable-parameter plant. Praise for the first edition: ...well written, interesting and easy to follow, so that it constitutes a valuable addition to the monographies in adaptive control for discrete-time linear systems... suitable (at least in part) for use in graduate courses in adaptive control.
The Origin of Life
Author: Raymond AronPublisher: Routledge
ISBN: 1351478001
Category : Science
Languages : en
Pages : 243
Book Description
Theoretical biology is still in its early stages as an academic discipline. There is even little agreement as to what topics it should deal with or in what manner it should precede; and it is only recently that philosophers felt called upon to notice the relevance of biological topics as evolution or perception to their traditional problems. This work is a publication of the International Union of Biological Sciences, the central organization of all the branches of biology. The main focus here is to explore the possibility of formulating some frame of concepts and methods around which theoretical biology can grow.The intention of this collective effort was that discussions would be concerned, not with the theory of particular biological processes, such as membrane permeability, genetics, and neural activity, but rather with an attempt to discover and formulate general concepts and logical relations characteristic of living as contrasted with inorganic systems. Further, this project is a consideration of implications these might have for general philosophy. Many well-known scientists contributed to this volume, such as J. Maynard Smith, Ernst Mayr, Brian Goodwin, and Renu Thom.The Origin of Life: Toward a Theoretical Biology explores the character of the problems facing any theory of general biology. It contains a series of chapters and exchanges discussing such topics as the origin of life, cellular differentiation, morphogensis, evolution, and indeterminacy in biological and physical systems, the organization of the brain, the statistical mechanics of non-linear oscillators, and many other topics. This is a pioneering volume by recognized leaders in an emerging field the first of four such works.

Centre and Periphery, Roots and Exile
Author: Friedemann SallisPublisher: Wilfrid Laurier Univ. Press
ISBN: 1554582962
Category : Music
Languages : en
Pages : 480
Book Description
This book examines the impact place and displacement can have on the composition and interpretation of Western art music, using as its primary objects of study the work of István Anhalt (1919–2012), György Kurtág (1926–), and Sándor Veress (1907–92). Although all three composers are of Hungarian origin, their careers followed radically different paths. Whereas, Kurtág remained in Budapest for most of his career, Anhalt and Veress left: the former in 1946 and immigrated to Canada and the latter in 1948 and settled in Switzerland. All three composers have had an extraordinary impact in the cultural environments within which their work took place. In the first section, “Place and Displacement,” contributors examine what happens when composers and their music migrate in the culturally complex world of the late twentieth century. The past one hundred years produced record numbers of refugees, and this fact is now beginning to resonate in the study of music. As Anhalt himself forcefully asserts, however, not all composers who emigrate should be understood as exiles. The first chapters of this book explore some of the problems and questions surrounding this issue. Essays in the second section, “Perspectives on Reception, Analysis, and Interpretation,” look at how performing acts of interpretation on music implies bringing the time, place, and identity of the musician, the analyst, and the teacher to bear on the object of study. Like Kodály, Kurtág considers his work to be “naturally” embedded in Hungarian culture, but he is also a quintessentially European artist. Much of his production—he is one of the twentieth century’s most prolific composers of vocal music—involves the setting of Hungarian texts, but in the late 1970s his cultural horizons expanded to include texts in Russian, German, French, English, and ancient Greek. The book explores how musicologists’ divergent cultural perspectives impinge on the interpretation of this work. The final section, “The Presence of the Past and Memory in Contemporary Music,” examines the impact time and memory can have on notions of place and identity in music. All living art taps into the personal and collective past in one way or another. The final four chapters look at various aspects of this relationship.
