Buch. Condizione: Neu. Neuware - Since the publication of the first edition of Fundamentals of Digital Switching in 1983, there has been substantial improvement in digital switching technology and in digital networks. Packet switching has advanced from a low-speed data-oriented switching approach into a robust broadband technology which supports services ranging from low-speed data to video. This technology has eclipsed the flexibility of circuit switching. Fiber optic cable has advanced since the first edition and has substantially changed the technology of transmission. to research in optical devices to find a still better means of This success has led switching. Digital switching systems continue to benefit from the 100-fold improvement in the capabilities of semiconductor devices which has occurred during the past decade. The chip industry forecasts a similar escalation in complexity during the next 10 years. Networks of switching systems have changed due to regulatory policy reform in many nations, including the breakup of the Bell System in the United States, the introduction of new types of carriers in Japan, competition in the United Kingdom, and a reexamination of public policy in virtually all nations. Standards bodies have been productive in specifying new capabilities for future networks involving interactive and distributive services through STM and A TM technologies.

Buch. Condizione: Neu. Neuware - Scientists are coming under increasing pressure from activist groups to stop animal experimentation, branded as cruel and unnecessary for improving human health. This attitude, however, stems from an unrealistic evaluation of the situation and distorted information about present scientific knowledge. There is no question that most medical progress - perhaps all, in fac- has been attained through knowledge derived initially from experiments in various animal species. There is practically no way of replacing animals in these investigations and so-called 'alternative methods' are in reality merely complementary. Tissue cultures, cell, microorganisms, enzymes, membranes, mathematical models - all are useful for preliminary screening tests and for testing hypotheses, but the complexity of a living organism is such that in vivo studies are essential before any test can responsibly be made in man. This book presents the proceedings of an international symposium organized in Strasbourg (October 24-25, 1988), with the aim of assessing present-day requirements as regards animal experimentation in research related to major medical and toxicological problems still awaiting solutions.

Buch. Condizione: Neu. Neuware - As the first edition of this book was going through the publication process, a revolution was taking place in the technologies available for the study of enzymes. The techniques of molecular biology, especially in genetic engineering of organisms and in site specific mutagenesis of genes, were established and were being brought into use to solve many problems in in enzymology. Added to these fundamental and applied science, not least advances the possibility of generating catalysts from antibodies has become a topic of major interest. These major innovations have changed the emphasis of much bioorganic research; whereas in the past, the protein was often the 'sleeping partner' ina study, its detailed function is now the major focus of scientific interest. Similarly in industry, the potential of genetically manipulated organisms to satisfy the needs for the production of chemicals and foodstuffs has been widely recognised. The second edition of 'Enzyme Chemistry, Impact and Applications' takes on board these new develop ments whilst maintaining the overall aims and views of the first edition. Many of the chapters have been completely rewritten to take account of advances in the last five years especially with regard to the impact of biologically based technologies. Although the book continues to approach its subject matter from the point of view of the chemist, the increased interdisciplinary content of much modern science will be obvious from the discussion.

Buch. Condizione: Neu. Neuware - This textbook is for a course in advanced solid-state theory. It is aimed at graduate students in their third or fourth year of study who wish to learn the advanced techniques of solid-state theoretical physics. The method of Green's functions is introduced at the beginning and used throughout. Indeed, it could be considered a book on practical applications of Green's functions, although I prefer to call it a book on physics. The method of Green's functions has been used by many theorists to derive equations which, when solved, provide an accurate numerical description of many processes in solids and quantum fluids. In this book I attempt to summarize many of these theories in order to show how Green's functions are used to solve real problems. My goal, in writing each section, is to describe calculations which can be compared with experiments and to provide these comparisons whenever available. The student is expected to have a background in quantum mechanics at the level acquired from a graduate course using the textbook by either L. I. Schiff, A. S. Davydov, or I. Landau and E. M. Lifshiftz. Similarly, a prior course in solid-state physics is expected, since the reader is assumed to know concepts such as Brillouin zones and energy band theory. Each chapter has problems which are an important part of the lesson; the problems often provide physical insights which are not in the text. Sometimes the answers to the problems are provided, but usually not.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -LOGLAN '88 belongs to the family of object oriented programming languages. It embraces all important known tools and characteristics of OOP, i.e. classes, objects, inheritance, coroutine sequencing, but it does not get rid of traditional imperative programming: primitive types do not need to be objects; records, static arrays, subtypes and other similar type contructs are admitted. LOGLAN has non-traditional memory model which accepts programmed deallocation but avoids dangling reference. The LOGLAN semantic model provides multi-level inheritance, which properly cooperates with module nesting. Parallelism in LOGLAN has an object oriented nature. Processes are treated like objects of classes and communication between processes is provided by alien calls similar to remote calls. 148 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides a comprehensive view of current developments in the theory of recursive reduced-order methods for singularly perturbed and weakly coupled linear control systems. The recursive methods offer several advantages: high accuracy can easily be achieved at low cost, parallel processing can be used, results are obtained under mild assumptions, and software and hardware implementation of the control algorithms is highly simplified. The book emphasizes mathematical developments as well as their application to solving practical problems. A number of real world examples demonstrating the usefulness of the theory are included. 216 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with algebraic criteria for root clustering (inclusion) in general regions in the complex plane. It is based on the view that there are three approaches to root clustering: composite matrices and polynomial symmetric matrices, and rational mappings. The book presents two main results of potential benefit to the reader. First, given a linear dynamical system, it is possible to analyze its relative stability. Second, for that system it is possible to construct a dynamic controller of fixed order for closed loop relative stability. The reader is assumed to have some knowledge of linear algebra and the theory of complex variables. The book is aimed at systems and control researchers, mathematicians and physicists. 168 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book provides a simple introduction to a nonlinear theory of generalized functions introduced by J.F. Colombeau, which gives a meaning to any multiplication of distributions. This theory extends from pure mathematics (it presents a faithful generalization of the classical theory of C functions and provides a synthesis of most existing multiplications of distributions) to physics (it permits the resolution of ambiguities that appear in products of distributions), passing through the theory of partial differential equations both from the theoretical viewpoint (it furnishes a concept of weak solution of pde's leading to existence-uniqueness results in many cases where no distributional solution exists) and the numerical viewpoint (it introduces new and efficient methods developed recently in elastoplasticity, hydrodynamics and acoustics). This text presents basic concepts and results which until now were only published in article form. It is in- tended for mathematicians but, since the theory and applications are not dissociated it may also be useful for physicists and engineers. The needed prerequisites for its reading are essentially reduced to the classical notions of differential calculus and the theory of integration over n-dimensional euclidean spaces.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 232 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The present study will help answer questions of tree type evolution, function, optimum, and tree construction types, using the approach of constructional morphology which to date has been widely neglected in palaeobotany and botany. First, the evolution pattern of the earliest Devonian trees is analyzed and explained, including a brief introduction of tree biomechanics. Then fossil and recent trees are studied from the viewpoint of constructional morphology with the main emphasis on the trunk as the most characteristic element of a tree. The various trunk constructions are classified into functional construction types, which are described and analyzed with respect to their biomechanical and biological properties. This functional comparison shows that the basic trunk constructions all appear in the Devonian, have specific advantages and disadvantages and constrain the possible growth habit of a tree. This study based on modern and fossil trees not only leads to a description but also to a causal understanding of the evolution and biology of the various tree types.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 172 pp. Englisch.
