Buch. Condición: Neu. Neuware - Due in July.This is an advanced textbook based on lectures delivered by a well-known specialist at the Moscow Physico-Technical Institute. The author makes the reader an active participant by asking questions, hinting, giving direct recommendations, comparing different methods, and discussing 'pessimistic' and 'optimistic' approaches to numerical analysis in a short time.Since matrix analysis underlies numerical methods and the author is an expert in this field, emphasis is on methods and algorithms of matrix analysis. Also considered are function approximations, methods of solving nonlinear equations, and minimization methods. Alongside classical methods, new results and approaches developed over the last few years are discussed.…

Buch. Condición: Neu. Neuware - One of the main goals of optimal control theory is to provide a theoretical basis for choosing an appropriate controller for whatever system is under consideration by the researcher or engineer. Two popular norms that have proved useful are known as H-2 and H - infinity control. The first has been particularly applicable to problems arising in the aerospace industry. However, most industrial problems are badly modeled and the second norm proved to be more appropriate when the actual conditions of the problem did not conform to the stipulated conditions of the theory. This book takes the topic of H-infinity control as a point of departure and pursues an improved controller design which has been suggested in the mainstream of robust control. Its main theme, minimum entropy control, provides a means of trading off some of the features of other control problems. The book is aimed at research workers in networking systems as well as those in operator theory and linear multivariable control. The use of stochastic methods makes the book also of importance to the circuits and systems community.

Buch. Condición: Neu. Neuware - Nature learned long ago how useful proteins are as a diverse set of building blocks to make materials with very diverse properties. Spider webs, egg whites, hair follicles, and skeletal muscles are all largely protein. This book provides a glimpse into both nature's strategies for the design and produc tion of protein-based materials, and how scientists have been able to go beyond the constraints of natural materials to produce synthetic analogs with potentially wider ranges of properties. The work presented is very much the beginning of the story. Only recently has there been much progress in obtaining a molecular understanding of some of nature's com plex materials, and the mimicry or replacement of these by synthetic or genetically engineered variants is a field still in its infancy. Yet this book will serve as a useful introduction for those wishing to get started in what is sure to be an active and productive field throughout the 21st century. The authors represent a wide range of interests and expertise, and the topics chosen are comprehensive. Charles R. Cantor Center for Advanced Biotechnology Boston University Series Preface The properties of materials depend on the nature of the macromolecules, small molecules and inorganic components and the interfaces and interac tions between them. Polymer chemistry and physics, and inorganic phase structure and density are major factors that influence the performance of materials.…

Buch. Condición: Neu. Neuware - This monograph is based on the author's results on the Riemannian ge ometry of foliations with nonnegative mixed curvature and on the geometry of sub manifolds with generators (rulings) in a Riemannian space of nonnegative curvature. The main idea is that such foliated (sub) manifolds can be decom posed when the dimension of the leaves (generators) is large. The methods of investigation are mostly synthetic. The work is divided into two parts, consisting of seven chapters and three appendices. Appendix A was written jointly with V. Toponogov. Part 1 is devoted to the Riemannian geometry of foliations. In the first few sections of Chapter I we give a survey of the basic results on foliated smooth manifolds (Sections 1.1-1.3), and finish in Section 1.4 with a discussion of the key problem of this work: the role of Riemannian curvature in the study of foliations on manifolds and submanifolds.…

Buch. Condición: Neu. Neuware - The main purpose of the present volume is to give a survey of some of the most significant achievements obtained by topological methods in nonlin ear analysis during the last three decades. It is intended, at least partly, as a continuation of Topological Nonlinear Analysis: Degree, Singularity and Varia tions, published in 1995. The survey articles presented are concerned with three main streams of research, that is topological degree, singularity theory and variational methods, They reflect the personal taste of the authors, all of them well known and distinguished specialists. A common feature of these articles is to start with a historical introduction and conclude with recent results, giving a dynamic picture of the state of the art on these topics. Let us mention the fact that most of the materials in this book were pre sented by the authors at the 'Second Topological Analysis Workshop on Degree, Singularity and Variations: Developments of the Last 25 Years,' held in June 1995 at Villa Tuscolana, Frascati, near Rome.

Buch. Condición: Neu. Neuware - Andrej V. Cherkaev and Robert V. Kohn In the past twenty years we have witnessed a renaissance of theoretical work on the macroscopic behavior of microscopically heterogeneous mate rials. This activity brings together a number of related themes, including: ( 1) the use of weak convergence as a rigorous yet general language for the discussion of macroscopic behavior; (2) interest in new types of questions, particularly the 'G-closure problem,' motivated in large part by applications of optimal control theory to structural optimization; (3) the introduction of new methods for bounding effective moduli, including one based on 'com pensated compactness'; and (4) the identification of deep links between the analysis of microstructures and the multidimensional calculus of variations. This work has implications for many physical problems involving optimal design, composite materials, and coherent phase transitions. As a result it has received attention and support from numerous scientific communities, including engineering, materials science, and physics as well as mathematics. There is by now an extensive literature in this area. But for various reasons certain fundamental papers were never properly published, circu lating instead as mimeographed notes or preprints. Other work appeared in poorly distributed conference proceedings volumes. Still other work was published in standard books or journals, but written in Russian or French. The net effect is a sort of 'gap' in the literature, which has made the subject unnecessarily difficult for newcomers to penetrate.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The representation theory of Lie groups plays a central role in both clas sical and recent developments in many parts of mathematics and physics. In August, 1995, the Fifth Workshop on Representation Theory of Lie Groups and its Applications took place at the Universidad Nacional de Cordoba in Argentina. Organized by Joseph Wolf, Nolan Wallach, Roberto Miatello, Juan Tirao, and Jorge Vargas, the workshop offered expository courses on current research, and individual lectures on more specialized topics. The present vol ume reflects the dual character of the workshop. Many of the articles will be accessible to graduate students and others entering the field. Here is a rough outline of the mathematical content. (The editors beg the indulgence of the readers for any lapses in this preface in the high standards of historical and mathematical accuracy that were imposed on the authors of the articles. ) Connections between flag varieties and representation theory for real re ductive groups have been studied for almost fifty years, from the work of Gelfand and Naimark on principal series representations to that of Beilinson and Bernstein on localization. The article of Wolf provides a detailed introduc tion to the analytic side of these developments. He describes the construction of standard tempered representations in terms of square-integrable partially harmonic forms (on certain real group orbits on a flag variety), and outlines the ingredients in the Plancherel formula. Finally, he describes recent work on the complex geometry of real group orbits on partial flag varieties. 340 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The hypermedia authoring process has been vividly described in a special issue of the Economist as a combination of writing a book, a play, a film, and a radio or television show: A hypermedia document combines all these elements and adds some of its own. The author' s first job is to structure and explain all of the infor mation. The author then must distill the information into brief, descriptive nodes. Each node has to contain a Iist of the ingredients, and instructions on how the ingredients are mixed together to the greatest advantage. The structure of the material provided is translated into an architectural metaphor of some kind; much of the designer' s work is the creation of this imaginary space. Then, the designers must chart the details of what to animate, what to film, who to inter view, and how to arrange the information in the space tobe built [Eco95a]. This book presents guidelines, tools, and techniques for prospective authors such that they can design better hypermedia documents and applications. lt surveys the different techniques used to organize, search, and structure infor mation in a large information system. It then describes the algorithms used to locate, reorganize, and link data to enable navigation and retrieval. It Iooks in detail at the creation and presentation of certain types of visual information, namely algorithm animations. It introduces new mechanisms for editing audio and video data streams. 420 pp. Englisch.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book considers methods of approximate analysis of mechanical, elec tromechanical, and other systems described by ordinary differential equa tions. Modern mathematical modeling of sophisticated mechanical systems consists of several stages: first, construction of a mechanical model, and then writing appropriate equations and their analytical or numerical ex amination. Usually, this procedure is repeated several times. Even if an initial model correctly reflects the main properties of a phenomenon, it de scribes, as a rule, many unnecessary details that make equations of motion too complicated. As experience and experimental data are accumulated, the researcher considers simpler models and simplifies the equations. Thus some terms are discarded, the order of the equations is lowered, and so on. This process requires time, experimentation, and the researcher's intu ition. A good example of such a semi-experimental way of simplifying is a gyroscopic precession equation. Formal mathematical proofs of its admis sibility appeared some several decades after its successful introduction in engineering calculations. Applied mathematics now has at its disposal many methods of approxi mate analysis of differential equations. Application of these methods could shorten and formalize the procedure of simplifying the equations and, thus, of constructing approximate motion models. Wide application of the methods into practice is hindered by the fol lowing. 1. Descriptions of various approximate methods are scattered over the mathematical literature. The researcher, as a rule, does not know what method is most suitable for a specific case. 2. 252 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Science demands that all theory must be checked by experiment. Richard Feyn man, Nobel Laureate in physics (1965), reminds us in a wonderful quote that 'The test of all knowledge is experiment. Experiment is the sole judge of sci entific truth. ' 1 It is because nonlinear physics can be so profoundly counter intuitive that these laboratory investigations are so important. This manual is designed to be used with the text Nonlinear Physics with Maple for Scientists and Engineers. Understanding is enhanced when experiments are used to check so please attempt as many of the activities as you can. As you perform theory, these activities, we hope that you will be amazed and startled by strange behav ior, intrigued and terrorized by new ideas, and be able to amaze your friends as you relate your strange sightings! Remember that imagination is just as impor tant as knowledge, so exercise yours whenever possible. But please be careful, as nonlinear activities can be addicting, can provide fond memories, and can awaken an interest that lasts a lifetime. Although it has been said that a rose by any other name is still a rose, (with apologies to Shakespeare) the authors of this laboratory manual have, in an endeavor to encourage the use of these nonlinear investigations, called them experimental activities rather than experiments. A number of design innovations have been introduced: A. 152 pp. Englisch. …

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Unlike the conventional research for the general theory of stability, this mono graph deals with problems on stability and stabilization of dynamic systems with respect not to all but just to a given part of the variables characterizing these systems. Such problems are often referred to as the problems of partial stability (stabilization). They naturally arise in applications either from the requirement of proper performance of a system or in assessing system capa bility. In addition, a lot of actual (or desired) phenomena can be formulated in terms of these problems and be analyzed with these problems taken as the basis. The following multiaspect phenomena and problems can be indicated: - 'Lotka-Volterra ecological principle of extinction;' - focusing and acceleration of particles in electromagnetic fields; - 'drift' of the gyroscope axis; - stabilization of a spacecraft by specially arranged relative motion of rotors connected to it. Also very effective is the approach to the problem of stability (stabilization) with respect to all the variables based on preliminary analysis of partial sta bility (stabilization). A. M. Lyapunov, the founder of the modern theory of stability, was the first to formulate the problem of partial stability. Later, works by V. V. Rumyan tsev drew the attention of many mathematicians and mechanicians around the world to this problem, which resulted in its being intensively worked out. The method of Lyapunov functions became the key investigative method which turned out to be very effective in analyzing both theoretic and applied problems. 446 pp. Englisch.…
