Buch. Zustand: Neu. Neuware - Progress in the numerical simulation of turbulence has been rapid in the 1990s. New techniques both for the numerical approximation of the Navier-Stokes equations and for the subgrid-scale models used in large-eddy simulation have emerged and are being widely applied for both fundamental and applied engineering studies, along with novel ideas for the performance and use of simulation for compressible, chemically reacting and transitional flows. This collection of papers from the second ERCOFTAC Workshop on Direct and Large-Eddy Simulation, held in Grenoble in September 1996, presents the key research being undertaken in Europe and Japan on these topics. Describing in detail the ambitious use of DNS for fundamental studies and of LES for complex flows of potential and actual engineering importance, this volume will be of interest to all researchers active in the area.…

Buch. Zustand: Neu. Neuware - Wireless personal communications, or wireless as it is now being called, has arrived. The hype is starting to fade, and the hard work of deploying new systems and services for personal communications is underway. In the United States, the FCC propelled the wireless era from infancy to mainstream with a $7.7 billion auction of 60 MHz of radio spectrum in the 180011900 MHz band. With the largest single sale of public property in the history of mankind mostly complete, the resources of the entire world are being called upon to develop inexpensive, rapidly deployable wireless systems and sub scriber units for an industry that is adding slbscribers at greater than 50% annual rate. This growth is commonplace for wireless service companies throughout the world, and in the U.S., where as many as 7 licensed wireless service providers may be competing for cellularlPCS customers within the next couple of years, differentiators in cost, qual ity, service, and coverage will become critical to customer acceptance and use. Many of these issues are discussed in the papers included in this book.…

Buch. Zustand: Neu. Neuware - invoking the fluctuation-dissipation theorems of Einstein and 2 more recently those of Callen and Kubo in order to get to manageable results. In this manner, great strides have been made in the development of the many-body problem without reaching the necessity to legitimize thermodynamics. Ther modynamics and statistical mechanics were used successful ly as bridges and guides to get the new ideas to conform to the macroscopic experiences (measurements). Hence the dis 3 interest of theoreticians. The frustration in attracting the at tention of the working physicists on this problem is vividly described in Carnap's (1978) account on the reception of his ideas and efforts at the Institute of Advanced Studies at Prin ceton where he worked on the Two Essays on Entropy; it al most amounted, he thought, to a conspiracy of silence. The priorities of theoretical physicists remain with the puzzles and the cranking at hand: Quantum Field Theory (QFT) and 'creation and annihilation' physics, solid state physics, - to mention only a few research areas - command the attention of those working on the research frontiers. Thermodynamics is taken for granted and is thought to be an almost depleted research area. Whatever the subterfuges, the hand-waving arguments, the paedagogical red herrings, the procedures work and nothing can be gained by allocating intellectual re sources to resolve ambiguities with few, if any, expected rewards. Down deep, all believe that the regularization of the field will one day be accomplished.…

Buch. Zustand: Neu. Neuware - Discretionary Managerial Behavior presents a quantification of the managerial behavior within decentralized organizations. The volume provides practical insights into the internal functioning of the firm, the relationships between the managers at different organizational echelons, and the conditioning effects of the organizational controls and the market environment external to the firm. It forms a basic contribution to the theoretical modeling, methodological and estimation procedures, and empirical insights into the nature and operation of managerial discretion in decentralized organizations. Both theoretical and empirical literature of organizational economics have not come to grips with the decision making process in such organizations. With this in perspective the volume describes four fundamentally new contributions. It presents: an approach to defining proximate objectives of managers at the divisional levels in a decentralized organization and the coordination by managers at higher levels, an approach to developing a modelling framework from a sound theoretical perspective in order to reflect the postulated behavior, an approach to defining an estimation technique to operationalize both (a) and (b) in a specific empirical context, and the richness of empirical insights which remained elusive for over thirty years. As such this study is an important step to make fundamental progress in the area of interface between business policy and microeconomic theory.…

Buch. Zustand: Neu. Neuware - Robotic systems are characterized by the intersection of computer intelligence with the physical world. This blend of physical reasoning and computational intelligence is well illustrated by the Tetrobot study described in this book. Tetrobot: A Modular Approach to Reconfigurable Parallel Robotics describes a new approach to the design of robotic systems. The Tetrobot approach utilizes modular components which may be reconfigured into many different mechanisms which are suited to different applications. The Tetrobot system includes two unique contributions: a new mechanism (a multilink spherical joint design), and a new control architecture based on propagation of kinematic solutions through the structure. The resulting Tetrobot system consists of fundamental components which may be mechanically reassembled into any modular configuration, and the control architecture will provide position control of the resulting structure. A prototype Tetrobot system has been built and evaluated experimentally. Tetrobot arms, platforms, and walking machines have been built and controlled in a variety of motion and loading conditions. The Tetrobot system has applications in a variety of domains where reconfiguration, flexibility, load capacity, and failure recovery are important aspects of the task. A number of key research directions have been opened by the Tetrobot research activities. Continuing topics of interest include: development of a more distributed implementation of the computer control architecture, analysis of the dynamics of the Tetrobot system motion for improved control of high-speed motions, integration of sensor systems to control the motion and shape of the high-dimensionality systems, and exploration of self-reconfiguration of the system. Tetrobot: A Modular Approach to Reconfigurable Parallel Robotics will be of interest to research workers, specialists and professionals in the areas of robotics, mechanical systems and computer engineering.…

Buch. Zustand: Neu. Neuware - South Africa's peaceful transition to democracy has gained it world recognition. This book gives a frank report on contemporary South African society and the challenges which the new nation faces. Sixteen social scientists, experts in fields as wide-ranging as economics, politics, and development planning, have compiled a social report on South Africa two years into democracy. The volume covers critical concerns which impact on the well-being of the average South African. The dozen chapters in the book present facts and figures as well as in-depth commentary on social issues which South Africa must address. The authors discuss the legacies of the past, including poverty and social inequality; problems of transition ranging from trauma to crime; and the hopes for the future which lie in economic growth and development, a deeper understanding of democracy, and a healthy dose of optimism. The book draws on information from a wide variety of sources including government statistics, independent social surveys, community research, and opinion polls. This rich data weaves a tapestry of the quality of life in South Africa for Africa watchers and the general public.…

Buch. Zustand: Neu. Neuware - Compiler technology is fundamental to computer science since it provides the means to implement many other tools. It is interesting that, in fact, many tools have a compiler framework - they accept input in a particular format, perform some processing and present output in another format. Such tools support the abstraction process and are crucial to productive systems development. The focus of Compiler Technology: Tools, Translators and Language Implementation is to enable quick development of analysis tools. Both lexical scanner and parser generator tools are provided as supplements to this book, since a hands-on approach to experimentation with a toy implementation aids in understanding abstract topics such as parse-trees and parse conflicts. Furthermore, it is through hands-on exercises that one discovers the particular intricacies of language implementation. Compiler Technology: Tools, Translators and Language Implementation is suitable as a textbook for an undergraduate or graduate level course on compiler technology, and as a reference for researchers and practitioners interested in compilers and language implementation.…

Buch. Zustand: Neu. Neuware - Angioplasty has completely transformed the treatment of coronary artery disease and is widely used, with more than 800,000 procedures performed worldwide per year. However, the enthusiasm for angioplasty is shadowed by restenosis, which remains a critical problem after the procedure, resulting in clinical recurrence in over a third of patients. Recently, the mechanisms of restenosis have been completely reappraised with an enriched understanding that the original concept of neointimal hyperplasia may not be accounting for the bulk of the problem. There is a desperate need to heighten understanding of the remodeling process at the molecular, cellular, and arterial level. Vascular remodeling is a well established concept in the field of atherosclerosis and hypertension, but only in recent years has its applicability to the field of restenosis become pivotal. Accordingly, the editors perceived the need to assemble the first book dedicated to the concept of coronary artery remodeling in restenosis, in order to clearly review the experiments leading to the remodeling hypothesis and integrate this with the neointimal hyperplasia (tumor) model for the development of the restenotic lesion. The authors of this book present their experience to facilitate the understanding of the mechanisms for coronary restenosis and remodeling. The various experimental models, clinical issues, and basic mechanisms are reviewed in detail, resulting in a fresh approach to a vexing clinical problem. Arterial Remodeling: A Critical Factor in Restenosis will be useful to the physician and trainee who have an interest in restenosis, and specifically in the major pathophysiologic process which determines the fate of arterial healing in patients following percutaneous coronary revascularization. It is hoped that this book will lay the foundation for more effective therapies that will reduce the chance of constrictive remodeling and improve the long-term efficacy of non-surgical coronary revascularization in the future.…
