Taschenbuch. Zustand: Neu. Neuware - Medieval Germany, 500-1300 is an interpretation of the foundation of Germany based upon the three most outstanding characteristics of the medieval polity: its division into several distinct peoples with their own customs, dialects, and economic interests from whom the later 'Germans' would be drawn; the imperial ambitions to which the successive German dynasties aspired; and the structure of German kingship, which was a military, religious, and juridical exercise of authority rather than a meticulous administration based upon scribal institutions.

Buch. Zustand: Neu. Neuware - Embedded core processors are becoming a vital part of today's system-on-a-chip in the growing areas of telecommunications, multimedia and consumer electronics. This is mainly in response to a need to track evolving standards with the flexibility of embedded software. Consequently, maintaining the high product performance and low product cost requires a careful design of the processor tuned to the application domain. With the increased presence of instruction-set processors, retargetable software compilation techniques are critical, not only for improving engineering productivity, but to allow designers to explore the architectural possibilities for the application domain. Retargetable Compilers for Embedded Core Processors, with a Foreword written by Ahmed Jerraya and Pierre Paulin, overviews the techniques of modern retargetable compilers and shows the application of practical techniques to embedded instruction-set processors. The methods are highlighted with examples from industry processors used in products for multimedia, telecommunications, and consumer electronics. An emphasis is given to the methodology and experience gained in applying two different retargetable compiler approaches in industrial settings. The book also discusses many pragmatic areas such as language support, source code abstraction levels, validation strategies, and source-level debugging. In addition, new compiler techniques are described which support address generation for DSP architecture trends. The contribution is an address calculation transformation based on an architectural model. Retargetable Compilers for Embedded Core Processors will be of interest to embedded system designers and programmers, the developers of electronic design automation (EDA) tools for embedded systems, and researchers in hardware/software co-design.

Buch. Zustand: Neu. Neuware - Field-programmable logic has been available for a number of years. The role of Field-Programmable Logic Devices (FPLDs) has evolved from simply implementing the system `glue-logic' to the ability to implement very complex system functions, such as microprocessors and microcomputers. The speed with which these devices can be programmed makes them ideal for prototyping. Low production cost makes them competitive for small to medium volume productions. These devices make possible new sophisticated applications, and bring up new hardware/software trade-offs and diminish the traditional hardware/software demarcation line. Advanced design tools are being developed for automatic compilation of complex designs and routings to custom circuits. Digital Systems Design and Prototyping Using Field Programmable Logic covers the subjects of digital systems design and (FPLDs), combining them into an entity useful for designers in the areas of digital systems and rapid system prototyping. It is also useful for the growing community of engineers and researchers dealing with the exciting field of FPLDs, reconfigurable and programmable logic. The authors' goal is to bring these topics to students studying digital system design, computer design, and related subjects in order to show them how very complex circuits can be implemented at the desk. Digital Systems Design and Prototyping Using Field Programmable Logic makes a pioneering effort to present rapid prototyping and generation of computer systems using FPLDs. From the Foreword: `This is a ground-breaking book that bridges the gap between digital design theory and practice. It provides a unifying terminology for describing FPLD technology. In addition to introducing the technology it also describes the design methodology and tools required to harness this technology. It introduces two hardware description languages (e.g. AHDL and VHDL). Design is best learned by practice and the book supports this notion with abundant case studies.' Daniel P.

Buch. Zustand: Neu. Neuware - The Fundamental Theorem of Algebra states that any complex polynomial must have a complex root. This basic result, whose first accepted proof was given by Gauss, lies really at the intersection of the theory of numbers and the theory of equations, and arises also in many other areas of mathematics. The purpose of this book is to examine three pairs of proofs of the theorem from three different areas of mathematics: abstract algebra, complex analysis and topology. The first proof in each pair is fairly straightforward and depends only on what could be considered elementary mathematics. However, each of these first proofs lends itself to generalizations, which in turn, lead to more general results from which the fundamental theorem can be deduced as a direct consequence. These general results constitute the second prooof in each pair. To arrive at each of the proofs, enough of the general theory of each relevant area is developed to understand the proof. In addition to the proofs and techniques themselves, many applications such as the insolvability of the quintic and the trascendence of e and pi are presented. Finally, a series of appendices give six additional proofs including a version of Gauss' original first proof. The book is intended for junior/senior level undergraduate mathematics students or first year graduate students. It is ideal for a 'capstone' course in mathematics. It could also be used as an alternative approach to an undergraduate abstract algebra course. Finally, because of the breadth of topics it covers it would also be ideal for a graduate course for mathmatics teachers.

Buch. Zustand: Neu. Neuware - Nowadays algebra is understood basically as the general theory of algebraic oper ations and relations. It is characterised by a considerable intrinsic naturalness of its initial notions and problems, the unity of its methods, and a breadth that far exceeds that of its basic concepts. It is more often that its power begins to be displayed when one moves outside its own limits. This characteristic ability is seen when one investigates not only complete operations, but partial operations. To a considerable extent these are related to algebraic operators and algebraic operations. The tendency to ever greater generality is amongst the reasons that playa role in explaining this development. But other important reasons play an even greater role. Within this same theory of total operations (that is, operations defined everywhere), there persistently arises in its different sections a necessity of examining the emergent feature of various partial operations. It is particularly important that this has been found in those parts of algebra it brings together and other areas of mathematics it interacts with as well as where algebra finds applica tion at the very limits of mathematics. In this connection we mention the theory of the composition of mappings, category theory, the theory of formal languages and the related theory of mathematical linguistics, coding theory, information theory, and algebraic automata theory. In all these areas (as well as in others) from time to time there arises the need to consider one or another partial operation.

Taschenbuch. Zustand: Neu. Neuware - This is the first volume of a comprehensive two-volume treatment of mechanics intended for students of civil and mechanical engineering. Used for several years in courses at Bradley University, the text presents statics in a clear and straightforward way and emphasizes problem solving. More than 350 examples clarify the discussion. The diskette included with the book contains EnSolve, a program written by the authors for solving problems in engineering mechanics. The program runs on Macintosh and PC-DOS computers and includes the following: - a unit converter for SI to US units and vice versa - a graphics program for plotting functions and data - a set of numerical subroutines The graphics module will, among other features, fit smooth splines between data, plot regression lines and curves, and change scales -- including from arithmetic to log and log-log. The numerical routines will, for example, find roots of polynomials, solve systems of equations, invert matrices, differentiate and integrate, and solve boundary-value problems.

Buch. Zustand: Neu. Neuware - As of today, Evolutionary Computing and Fuzzy Set Computing are two mature, wen -developed, and higbly advanced technologies of information processing. Bach of them has its own clearly defined research agenda, specific goals to be achieved, and a wen setUed algorithmic environment. Concisely speaking, Evolutionary Computing (EC) is aimed at a coherent population -oriented methodology of structural and parametric optimization of a diversity of systems. In addition to this broad spectrum of such optimization applications, this paradigm otTers an important ability to cope with realistic goals and design objectives reflected in the form of relevant fitness functions. The GA search (which is often regarded as a dominant domain among other techniques of EC such as evolutionary strategies, genetic programming or evolutionary programming) delivers a great deal of efficiency helping navigate through large search spaces. The main thrust of fuzzy sets is in representing and managing nonnumeric (linguistic) information. The key notion (whose conceptual as weH as algorithmic importance has started to increase in the recent years) is that of information granularity. It somewhat concurs with the principle of incompatibility coined by L. A. Zadeh. Fuzzy sets form a vehic1e helpful in expressing a granular character of information to be captured. Once quantified via fuzzy sets or fuzzy relations, the domain knowledge could be used efficiently very often reducing a heavy computation burden when analyzing and optimizing complex systems.

Buch. Zustand: Neu. Neuware - Reasoning in Boolean Networks provides a detailed treatment of recent research advances in algorithmic techniques for logic synthesis, test generation and formal verification of digital circuits. The book presents the central idea of approaching design automation problems for logic-level circuits by specific Boolean reasoning techniques. While Boolean reasoning techniques have been a central element of two-level circuit theory for many decades Reasoning in Boolean Networks describes a basic reasoning methodology for multi-level circuits. This leads to a unified view on two-level and multi-level logic synthesis. The presented reasoning techniques are applied to various CAD-problems to demonstrate their usefulness for today's industrially relevant problems. Reasoning in Boolean Networks provides lucid descriptions of basic algorithmic concepts in automatic test pattern generation, logic synthesis and verification and elaborates their intimate relationship to provide further intuition and insight into the subject. Numerous examples are provide for ease in understanding the material. Reasoning in Boolean Networks is intended for researchers in logic synthesis, VLSI testing and formal verification as well as for integrated circuit designers who want to enhance their understanding of basic CAD methodologies.

Buch. Zustand: Neu. Neuware - Human Face Recognition Using Third-Order Synthetic Neural Networks explores the viability of the application of High-order synthetic neural network technology to transformation-invariant recognition of complex visual patterns. High-order networks require little training data (hence, short training times) and have been used to perform transformation-invariant recognition of relatively simple visual patterns, achieving very high recognition rates. The successful results of these methods provided inspiration to address more practical problems which have grayscale as opposed to binary patterns (e.g., alphanumeric characters, aircraft silhouettes) and are also more complex in nature as opposed to purely edge-extracted images - human face recognition is such a problem. Human Face Recognition Using Third-Order Synthetic Neural Networks serves as an excellent reference for researchers and professionals working on applying neural network technology to the recognition of complex visual patterns.

Buch. Zustand: Neu. Neuware - It has been almost 15 years since the fIrst reports appeared indicating that adenosine exerted a .protective effect in ischemic and reperfused myocardium. Numerous experimental studies have shown that adenosine (both exogenous and endogenous adenosine) delays the onset of ischemic contracture, modulates myocardial metabolism during ischemia, attenuates reversible postischemic ventricular dysfunction (myocardial stunning), and reduces myocardial infarct size. Initial studies on adenosine's cardioprotective effect were based on its ability to stimulate postischemic ATP resynthesis, increase coronary blood flow, and reduce heart rate. Although these actions of adenosine are undoubtedly benefIcial to the ischemic/reperfused heart, it now appears that adenosine's cardioprotective effect may be exclusive of these properties. The immense growth in the number of articles on adenosine cardioprotection in the last several years has been related in large part to the hypothesis that adenosine plays a role in ischemic preconditioning. Ischemic preconditioning is the phenomenon in which a brief period of ischemia (and reperfusion) prior to a more prolonged occlusion reduces myocardial infarct size. This form of myocardial protection has received much interest because ischemic preconditioning has been shown to be the most potent means of reducing infarct size in all animal models thus far tested. In fact prior to studies implicating adenosine's role in ischemic preconditioning, adenosine's infarct reducing effect was not well recognized.

Buch. Zustand: Neu. Neuware - Autonomous agents or multiagent systems are computational systems in which several computational agents interact or work together to perform some set of tasks. These systems may involve computational agents having common goals or distinct goals. Real-Time Search for Learning Autonomous Agents focuses on extending real-time search algorithms for autonomous agents and for a multiagent world. Although real-time search provides an attractive framework for resource-bounded problem solving, the behavior of the problem solver is not rational enough for autonomous agents. The problem solver always keeps the record of its moves and the problem solver cannot utilize and improve previous experiments. Other problems are that although the algorithms interleave planning and execution, they cannot be directly applied to a multiagent world. The problem solver cannot adapt to the dynamically changing goals and the problem solver cannot cooperatively solve problems with other problem solvers. This book deals with all these issues. Real-Time Search for Learning Autonomous Agents serves as an excellent resource for researchers and engineers interested in both practical references and some theoretical basis for agent/multiagent systems. The book can also be used as a text for advanced courses on the subject.

Buch. Zustand: Neu. Neuware - Zinc has an important role in human physiology due to its involvement in numerous enzymatic reactions and its other functions as part of hormones and structural proteins. As a consequence a wide variety of symptoms may occur in different states of zinc deficiency. Several diseases of the digestive tract can lead to zinc deficiency and consequently to deficiency symptoms. This book, the proceedings of an International Falk Workshop held in Freiburg, Germany, on 27 October 1996, aims at a dialogue between basic researchers and gastroenterologists in order to improve the understanding of the role of zinc in disorders of the digestive tract. Based on lectures on the role of zinc in cell biology, the pathophysiology of zinc deficiency and consequently the possibilities of zinc substitution in these disorders is discussed. It is hoped that this book will initiate fruitful discussions and collaborations leading to a better knowledge of the role of this trace element in gastroenterology.

Buch. Zustand: Neu. Neuware - This volume consitutes a summary of several years' multi-disciplinary research by a group of Swedish researchers. The project 'Sweden's Technological Systems and Future Development Potential' was initiated by the Swedish National Board for Industrial and Technical Development (NUTEK) and has been carried out at the Department of Industrial Management and Economics at Chalmers University of Technology in Gothenburg, the Research Policy Institute at the University of Lund, the Industrial Institute for Economic and Social Research (lUI) in Stockholm, and the Department of Industrial Economics and Management at the Royal Insitute of Technology, Stockholm, under the direction of Bo Carlsson, Case Western Reserve University, Cleveland, Ohio. The project group decided early on to focus fIrst on the technological system for factory automation - a relatively mature system of great importance to Swedish industry and in which Sweden has reached a leading position internationally - and then to shift the attention to other systems in various stages of development and with varying Swedish strength. The work on factory automation resulted in numerous papers and publications, summarized in a volume published in 1995 (Technological Systems and Economic Performance: The Case of Factory Automation, ed. Bo Carlsson. Dordrecht.

Buch. Zustand: Neu. Neuware - This volume brings together and expands on a body of research that I began in the early 1960s and have continued up to the present. It deals mainly with shiftwork-work that is performed during other than normal daytime hours. Shiftwork is a characteristic of economic life in the United States and abroad that has increased in importance over the years; according to the Bureau of Labor Statistics, one out of five full-time and part-time employees in the United States works on shifts. My interest in this field concerns fixed capital, specifically, changes in weekly hours worked by capital over long periods of time, and the signifi cance of those changes in the measurement oflong-run productivity change. In studies of growth, the measurement of capital input-by capital stocks or the services yielded by those stocks-typically makes no allowance for the changing hours worked by capital. Capital services are assumed to be propor tional to the stocks. Consequently, in analyses of output growth in a growth accounting framework, the effect of longer capital hours is a component of multifactor or total factor productivity growth.

Buch. Zustand: Neu. Neuware - The presentation and interpretation of visual information is essential to almost every activity in human life andmost endeavors of modern technology. This book examines the current status of what is known (and not known) about human vision, how human observers interpret visual data, and how to present such data to facilitate their interpretation and use. Written by experts who are able to cross disciplinary boundaries, the book provides an educational pathway through several models of human vision; describes how the visual response is analyzed and quantified; presents current theories of how the human visual response is interpreted; discusses the cognitive responses of human observers; and examines such applications as space exploration, manufacturing, surveillance, earth and air sciences, and medicine. The book is intended for everyone with an undergraduate-level background in science or engineering with an interest in visual science. This second edition has been brought up to date throughout and contains a new chapter on 'Virtual reality and augmented reality in medicine.'.

Buch. Zustand: Neu. Neuware - Chemical modification of polymers by reactive modifiers is no longer an academic curiosity but a commercial reality that has delivered a diverse range of speciality materials for niche markets: reactively grafted styrenic alloys, maleated polyolefins, super-tough nylons, silane modified and moisture-cured polyolefins, and thermoplastic elastomers, are but few exam ples of commercial successes. Although the approach of reactive modification of polymers has been largely achieved either in solution or in the solid state (through in situ reactions in polymer melts), it is the latter route that has attracted most attention in the last two decades owing to its flexibility and cost-effective ness. This route, referred to as reactive processing, focuses on the use of suitable reactive modifier(s) and the adoption of conventional polymer processing machinery, an extruder or a mixer, as a chemical reactor, to perform in situ targeted reactions for chemical modification of preformed polymers. This relatively simple, though scientifically highly challenging, approach to reactive modification offers unique opportunities in exploiting various reactive modifiers for the purpose of altering and transforming in a controlled manner the properties of preformed commercial polymers into new/speciality materials with tailor-made properties and custom-designed performance for target applications. Such an economically attractive route constitutes a radical diversion away from the traditional practices of manufacturing new polymers from monomers which involves massive in vestments in sophisticated technologies and chemical plants.
