A rich variety of books devoted to dynamical chaos, solitons, self-organization has appeared in recent years. These problems were all considered independently of one another. Therefore many of readers of these books do not suspect that the problems discussed are divisions of a great generalizing science – the theory of oscillations and waves. This science is not some branch of physics or mechanics, it is a science in its own right. It is in some sense a meta-science. In this respect the theory of oscillations and waves is closest to mathematics. In this book we call the reader’s attention to the present-day theory of non-linear oscillations and waves. Oscillatory and wave processes in the systems of diversified physical natures, both periodic and chaotic, are considered from a unified poin t of view . The relation between the theory of oscillations and waves, non-linear dynamics and synergetics is discussed. One of the purposes of this book is to convince reader of the necessity of a thorough study popular branches of of the theory of oscillat ions and waves, and to show that such science as non-linear dynamics, synergetics, soliton theory, and so on, are, in fact , constituent parts of this theory. The primary audiences for this book are researchers having to do with oscillatory and wave processes, and both students and post-graduate students interested in a deep study of the general laws and applications of the theory of oscillations and waves.

Oscillations en biologie Analyse qualitative et modèles


Free Download Oscillations en biologie: Analyse qualitative et modèles by Jean-Pierre Françoise
Français | PDF (True) | 2005 | 189 Pages | ISBN : 3540251529 | 1.6 MB
Par sa nature pluridisciplinaire, ce livre s’adresse à un large public de mathématiciens, physiciens et ingénieurs s’intéressant aux aspects théoriques des phénomènes périodiques, de même qu’aux étudiants en sciences de la vie intéressés par les outils mathématiques de la modélisation. Les oscillations complexes mises en évidence dans les systèmes physiologiques s’analysent par des modèles. Cet ouvrage se propose de présenter et de développer les mathématiques nécessaires à leur compréhension. On présente en particulier les notions d’excitabilité, de bistabilité, de synchronisation et d’oscillations en salves dans le cadre de l’analyse qualitative.

Digital Processing of Random Oscillations

English | 2019 | ISBN: 3110625008 | 140 Pages | EPUB (True) | 5 MB
This book deals with the autoregressive method for digital processing of random oscillations. The method is based on a one-to-one transformation of the numeric factors of the Yule series model to linear elastic system characteristics. This parametric approach allowed to develop a formal processing procedure from the experimental data to obtain estimates of logarithmic decrement and natural frequency of random oscillations. ments at the points of half-power of the observed oscillations. For a time-domain presentation, evaluation of the decrement requires measuring covariance values delayed by a time interval divisible by T0. Both estimation procedures are derived from a continuous description of research phenomena, so the accuracy of estimates is linked directly to the adequacy of discrete representation of random oscillations. This approach is similar a concept of transforming differential equations to difference ones with derivative approximation by corresponding finite differences. The resulting discrete model, being an approximation, features a methodical error which can be decreased but never eliminated. To render such a presentation more accurate it is imperative to decrease the discretization…
