With the advent of a host of new materials ranging from shape memory alloys to biomaterials to multiphase alloys, acquiring the capacity to model inelastic behavior and to choose the right model in a commercial analysis software has become a pressing need for practicing engineers. Even with the traditional materials, there is a continued emphasis on optimizing and extending their full range of capability in the applications. This textbook builds upon the existing knowledge of elasticity and thermodynamics, and allows the reader to gain confidence in extending one's skills in understanding and analyzing problems in inelasticity. By reading this textbook and working through the assigned exerci...
This book deals with analytic problems related to some developments and generalizations of the Boltzmann equation toward the modeling and qualitative analysis of large systems that are of interest in applied sciences. These generalizations are documented in the various surveys edited by Bellomo and Pulvirenti with reference to models of granular media, traffic flow, mathematical biology, communication networks, and coagulation models. The first generalization dealt with refers to the averaged Boltzmann equation, which is obtained by suitable averaging of the distribution function of the field particles into the action domain of the test particle. This model is further developed to describe equations with dissipative collisions and a class of models that are of interest in mathematical biology. In this latter case the state of the particles is defined not only by a mechanical variable but also by a biological microscopic state.
This seminal book unites three different areas of modern science: the micromechanics and nanomechanics of composite materials; wavelet analysis as applied to physical problems; and the propagation of a new type of solitary wave in composite materials, nonlinear waves. Each of the three areas is described in a simple and understandable form, focusing on the many perspectives of the links among the three. All of the techniques and procedures are described here in the clearest and most open form, enabling the reader to quickly learn and use them when faced with the new and more advanced problems that are proposed in this book. By combining these new scientific concepts into a unitary model and ...
Annotation Ito (North Carolina State U.) and Kappel (U. of Graz, Austria) offer a unified presentation of the general approach for well-posedness results using abstract evolution equations, drawing from and modifying the work of K. and Y. Kobayashi and S. Oharu. They also explore abstract approximation results for evolution equations. Their work is not a textbook, but they explain how instructors can use various sections, or combinations of them, as a foundation for a range of courses.

The complete volume 12 of Medical Progress through Technology is devoted to the work of colleagues in Japan. Additionally, whole authority and responsibility both for the election of topics and for the reviewing procedure had been delegated to Guest Editors from Japan. What are the objectives of this special issue and why has Japan been elected to present itself in this way? International journals such as Medical Progress through Technology usually contain papers from authors all over the world. Such issues provide a rather comprehensive survey on different scientific projects but do not reflect the standard and extent of medical technology in a certain country. I think that issues like the ...
Over the last decade of the 20th century, many improvements took place in the field of metrology and fundamental constants. These developments and improvements are discussed in this book. The old caesium SI second definition has found a new realization with the fountain approach, replacing the classical thermal atomic beam. The use of cold atom techniques, slowed down and cooled, has opened a number of unexpected avenues for metrology and fundamental constants, one of these possibilities being the atom interferometry. Another development was the demonstration of the possiblility of performing a direct frequency division in the visible, using short femtosecond pulses. Many other developments are also discussed.
This volume contains the selected manuscripts of the papers presented at the Second IDMME Conference on "Integrated Design and Manufacturing in Mechanical Engineering", held in Compiegne, France, at the University of Technology of Compiegne, May 27-29, 1998. The purpose of the Conference was to present and discuss topics dealing with the optimization of product design and manufacturing processes with particular attention to (1) the analysis and optimum design of mechanical parts and mechanisms (2) the modeling of forming processes (3) the development of computer aided manufacturing tools (4) the methodological aspects of integrated design and manufacturing in adapted technical and human environments. The initiative of the conference and the organization thereof is mainly due to the efforts of the french PRIMECA group (Pool of Computer ResoUfces for Mechanics). The international Institution for Production Engineering Research (C.I.R.P.) was helpful to attract international participants. The conference brought together three hundred and twenty worldwide participants.
The electric field of the heart was described diagrammatically for the first time by A. Waller in 1888. However, it was not until a little more than ten years ago that with the development of micro electronic techniques, it became accessible to biophysical modeling, to exact physiological measurements, and to application in advanced clinical diagnosis. These possibilities opened the way to the treatment of questions which are called the direct and the inverse solution of the cardioelectric problem. Several groups of investigators are now working to achieve a complete biophysical and physiological description of the generation of the cardiac electric field. This work could well form the basis...
Bioelectric and Biomagnetic Fields: Theory and Applications in Electrocardiology begins with a general description of the development of extracellular bioelectric and biomagnetic fields and the methods used in their analysis and measurement. The most effective electrodynamic models and most modern approaches to topographical (synchronous multilead) measurements of the field are reviewed. The next section discusses the major approaches to analysis of the inverse problem with a detailed description of multipole technique applied to the bioelectric and biomagnetic fields measured on or near the body surface. Special emphasis is placed on the interrelationship between the electric and magnetic fields of the same bioelectric generator. The last section explains the new approaches to chronotopographical representation of the electrophysiological characteristics deduced from the parameters of the bioelectric generator. The text includes the most recent experimental protocols and results from studies in electro- and magnetocardiology and electro- and magnetoneurology.
This book collects up-to-date papers from world experts in a broad variety of relevant applications of approximation theory, including dynamical systems, multiscale modelling of fluid flow, metrology, and geometric modelling to mention a few. The 14 papers in this volume document modern trends in approximation through recent theoretical developments, important computational aspects and multidisciplinary applications. The book is arranged in seven invited surveys, followed by seven contributed research papers. The surveys of the first seven chapters are addressing the following relevant topics: emergent behaviour in large electrical networks, algorithms for multivariate piecewise constant app...
