Buch. Condición: Neu. Neuware -Term rewriting techniques are applicable in various fields of computer sci ence: in software engineering (e.g., equationally specified abstract data types), in programming languages (e.g., functional-logic programming), in computer algebra (e.g., symbolic computations, Grabner bases), in pro gram verification (e.g., automatically proving termination of programs), in automated theorem proving (e.g., equational unification), and in algebra (e.g., Boolean algebra, group theory). In other words, term rewriting has applications in practical computer science, theoretical computer science, and mathematics. Roughly speaking, term rewriting techniques can suc cessfully be applied in areas that demand efficient methods for reasoning with equations. One of the major problems one encounters in the theory of term rewriting is the characterization of classes of rewrite systems that have a desirable property like confluence or termination. If a term rewriting system is conflu ent, then the normal form of a given term is unique. A terminating rewrite system does not permit infinite computations, that is, every computation starting from a term must end in a normal form. Therefore, in a system that is both terminating and confluent every computation leads to a result that is unique, regardless of the order in which the rewrite rules are applied. This book provides a comprehensive study of termination and confluence as well as related properties.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 436 pp. Englisch.

Buch. Condición: Neu. Neuware -As e-commerce becomes the norm of business transactions and information be comes an essential commodity, it is vital that extensive efforts be made to examine and rectify the problems with the underlying architectures, processes, methods, that are involved in providing and and tools, as well as organizational structures, utilizing services relating to information technology. Such a holistic view of the relevant structures is required in order to identify all of the key aspects that can affect network security. Unfortunately, today's systems and practices, although they have proved to be useful and become widespread, contain significant unnecessary complexity. This complexity provides many loopholes that make systems and practices vulnerable to malicious attacks by hackers as well as by individual and organized criminals. FUrther, there are enormous risks due to malfunction of the systems. The holes in the network system cannot simply be plugged up by the use of cryptography and firewalls. While many changes need to be made in operating systems and system software with respect to security, this alone does not solve the problem. The problems cannot be solved by addressing only a single key aspect of network security. A holistic approach is required. Sumit Ghosh has provided in this book such a holistic view of the area of network security. Thus, it is a most welcome contribution.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Buch. Condición: Neu. Neuware -Optical communications networks are an essential part of the world wide te- communication infrastructure . The number of users of present and future telecommunication services like Internet, web browsing and tele-education is expected to increase dramatically . As a consequence there is an imminent - mand for high broadband and high capacity communication systems. A prom- ing solution is found in the concept of all-optical networks . These networks exploit the vast capacity of the optical fiber by using multiplexing techniques that allow for an overall capacity of terabits per second. Channels are routed and switched in the optical domain . In this manner data channels are carried from the receiver side to its destination making use of optical transmission techniques . Wavelength division multiplexing (WDM) is a transmission technique that has dramatically increased the capacity of optical transmission systems. WDM allows for transmission of several channels over a single optical fiber by - ing different wavelength as the channel carrier . Optical switching and routing techniques are also being developed to cope with the high data speeds and n- ber of channel carried in the optical fibers. These functionalities are provided by optical crossconnects. The use of transmission techniques such as WDM in combination with optical crossconnects is enabling optical networking at high bit-rates reaching terabits per second . These techniques also offer ways to improve the network flexibility and configurability .Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Buch. Condición: Neu. Neuware -Early studies of political behavior examined the sociological, attitudinal, and rational determinants of political behavior. However, none of these approaches provided a descriptive model of how people process political information and make political decisions under naturalistic conditions that involve limited cognitive capacity and motivation. Fortunately, contemporary approaches within the field of political psychology have begun to address these concerns. Inspired by recent advances in the area of social psychology, researchers are rapidly developing more realistic and detailed models of the psychological process that determines political judgements and behavior. Early attempts to merely predict political behavior have been replaced by an attempt to describe the actual process whereby individuals gather, interpret, exchange, and combine information to arrive at a political judgement or decision. This volume provides comprehensive coverage of this pioneering era of research in political psychology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Condición: Neu. Neuware -This book arose out of a paper that I wrote for the World Bank at the request of Ariel Dinar, the editor for the series in which this volume appears. I began that paper by pointing to the growing importance of demand-side considerations in water resources: 'The provision of potable water is one of government's oldest functions with evidence of this activity stretching back thousands of years. During much of that time, water demands were taken as exogenously given and the principle task of authorities was defined as an engineering one: how to supply a given quantity of water at least cost. In recent years, however, concerns have arisen from observations of excessive water use, degraded water quality and continued inadequate service for many, especially the very poor. As a result of these and other concerns, there is a growing effort to view water resource allocation from a perspective that incorporates consumers' preferences along with supply constraints into management plans. ' (Renzetti, 2000, p. 123). The purpose of this volume is to examine, in greater detail than was possible in that article, what is known regarding the economic characteristics of the demand for water. Thus, this book is meant to be an extended critical review of the state of the art.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 208 pp. Englisch.

Buch. Condición: Neu. Neuware -For people interested in risk management, medical activity represents a stimulating field of study and thought. On the one hand, progress in medical knowledge and technology tends to reduce the risks to survival that individuals would face in the absence of appropriate diagnostic or therapeutic instruments. On the other hand, new medical technologies simultaneously create their own specific risks, sometimes simply because their effects are less well-known than those of established ones. In a sense any medical progress simultaneously generates new risks while destroying old ones. Moreover, unlike many financial risks that can be either divided or transferred to others (e.g. through diversification, insurance or social security) the personal aspects of medical risks are by essence indivisible and non-transferable. As a result, they are in a sense more threatening than financial risks for risk averse patients. These two facts explain and justify the growing interest in risk economics for the fields of medical decision making and health economics.In Risk and Medical Decision Making, part 1 is developed inside the expected utility (E-U) model and analyses how comorbidity risks affect the well-known 'test-treatment' thresholds. Part 2 is devoted to a specific non E-U model with the same purpose: how would one define a threshold in this context and how would one value a diagnostic test In each of these two parts both diagnostic and therapeutic risks are considered.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 144 pp. Englisch.

Buch. Condición: Neu. Neuware -Mobile Computation with Functions explores distributed computation with languages which adopt functions as the main programming abstraction and support code mobility through the mobility of functions between remote sites. It aims to highlight the benefits of using languages of this family in dealing with the challenges of mobile computation. The possibility of exploiting existing static analysis techniques suggests that having functions at the core of mobile code language is a particularly apt choice. A range of problems which have impact on the safety, security and performance are discussed. It is shown that types extended with effects and other annotations can capture a significant amount of information about the dynamic behavior of mobile functions, and offer solutions to the problems under investigation. This book includes a survey of the languages Concurrent ML, Facile and PLAN which inherit the strengths of the functional paradigm in the context of concurrent and distributed computation. The languages which are defined in the subsequent chapters have their roots in these languages. 156 pp. Englisch.

Buch. Condición: Neu. Neuware -Colleagues and friends of Dan Yaron submitted the following tributes. While each submission comes from an individual who knew Dan in a very different way, they all remark on his immeasurable contributions to the field of agricultural eco nomics, his unique approach, which combines his training and experience with his scientific background, and the admirable professionalism and civility that was apparent in every project he undertook. His work, initially inspired by the chal lenge of farmers in the arid Negev, eventually took him to the United States to work with universities and to serve on commissions furnishing his research with global applicability. Dan is not only admired for his enormous contributions to the vast body of research available in his field, but also for the commitment and dedi cation he epitomized. He will be greatly missed by those of us who were fortunate enough to make his acquaintance. ELIFEINERMAN The Hebrew University of Jerusalem, Rehovot, Israel Dan Yaron, my teacher and mentor of blessed memory, was a man of wisdom, thought, counsel and deeds. His many talents, his endless energy and his ambition led him to blaze new trails in research, to ask the relevant questions while separat ing the wheat from the chaff, and to answer them while mastering the most ad vanced scientific analyses.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Buch. Condición: Neu. Neuware -There has been continuing interest in the improvement of the speed of Digital Signal processing. The use of Residue Number Systems for the design of DSP systems has been extensively researched in literature. Szabo and Tanaka have popularized this approach through their book published in 1967. Subsequently, Jenkins and Leon have rekindled the interest of researchers in this area in 1978, from which time there have been several efforts to use RNS in practical system implementation. An IEEE Press book has been published in 1986 which was a collection of Papers. It is very interesting to note that in the recent past since 1988, the research activity has received a new thrust with emphasis on VLSI design using non ROM based designs as well as ROM based designs as evidenced by the increased publications in this area. The main advantage in using RNS is that several small word-length Processors are used to perform operations such as addition, multiplication and accumulation, subtraction, thus needing less instruction execution time than that needed in conventional 16 bitl32 bit DSPs. However, the disadvantages of RNS have b. een the difficulty of detection of overflow, sign detection, comparison of two numbers, scaling, and division by arbitrary number, RNS to Binary conversion and Binary to RNS conversion. These operations, unfortunately, are computationally intensive and are time consuming.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 270 pp. Englisch.

The specifications are conveniently tabulated throughout the book and span a level of details from the noise figure and linearity requirements of RF blocks down to such circuit details as, e.g., DC gain, settling behavior, noise and matching requirements of amplifiers (OTAs) in the data converter.Multi-Standard CMOS Wireless Receivers: Analysis and Design serves as a reference for RF IC and mixed-signal designers, wireless receiver system designers, design managers and project leaders in industry, particularly those in the wireless semiconductor industry.

Buch. Condición: Neu. Neuware -Agricultural Productivity: Measurement and Sources of Growth addresses measurement issues and techniques in agricultural productivity analysis, applying those techniques to recently published data sets for American agriculture. The data sets are used to estimate and explain state level productivity and efficiency differences, and to test different approaches to productivity measurement. The rise in agricultural productivity is the single most important source of economic growth in the U.S. farm sector, and the rate of productivity growth is estimated to be higher in agriculture than in the non-farm sector. It is important to understand productivity sources and to measure its growth properly, including the effects of environmental externalities.Both the methods and the data can be accessed by economists at the state level to conduct analyses for their own states. In a sense, although not explicitly, the book provides a guide to using the productivity data available on the website of the U.S. Department of Agriculture/Economic Research Service. It should be of interest to a broad spectrum of professionals in academia, the government, and the private sector.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.

Buch. Condición: Neu. Neuware -Without a clear and organized view of where and how entrepreneurship manifests itself, policy makers have been left in uncharted waters without an analytical compass.The purpose of this book is to provide such an analytical compass for directing how public policy can shape and promote entrepreneurship. We do this in two ways. The first is to provide a framework for policymakers and scholars to understand what determines entrepreneurship. The second is to apply this framework to a series of cases, or country studies. In particular, this book seeks to answer three questions about entrepreneurship: What has happened over time Why did it happen And, what has been the role of government policy The cornerstone of the book is the proposed Eclectic Theory of Entrepreneurship. The goal of the Eclectic Theory is to provide a unified framework for understanding and analyzing the determinants of entrepreneurship. The Eclectic Theory of entrepreneurship integrates the different strands from relevant fields into a unifying, coherent framework. At the heart of the Eclectic Theory is the integration of factors shaping the demand for entrepreneurship on the one hand, with those influencing the supply of entrepreneurs on the other hand. The key to understanding the role of public policy is through identifying those channels shifting either the demand for or the supply of entrepreneurship by policy instruments.The findings in this book show that, by utilizing the framework provided by the Eclectic Theory of Entrepreneurship, it is within the grasp of policymakers to identify the determinants of entrepreneurship in a particular country setting at a particular point in time. This will be essential in formulating new public policies to promote entrepreneurship and, ultimately, economic growth, job creation and international competitiveness.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 258 pp. Englisch.

Buch. Condición: Neu. Neuware - Linking People, Place, and Policy: A GIScience Approach describes a breadth of research associated with the study of human-environment interactions, with particular emphasis on land use and land cover dynamics. This book examines the social, biophysical, and geographical drivers of land use and land cover patterns and their dynamics, which are interpreted within a policy-relevant context. Concepts, tools, and techniques within Geographic Information Science serve as the unifying methodological framework in which landscapes in Thailand, Ecuador, Kenya, Cambodia, China, Brazil, Nepal, and the United States are examined through analyses conducted using quantitative, qualitative, and image-based techniques.Linking People, Place, and Policy: A GIScience Approach addresses a need for a comprehensive and rigorous treatment of GIScience for research and study within the context of human-environment interactions. The human dimensions research community, land use and land cover change programs, and human and landscape ecology communities, among others, are collectively viewing the landscape within a spatially-explicit perspective, where people are viewed as agents of landscape change that shape and are shaped by the landscape, and where landscape form and function are assessed within a space-time context. This book articulates some of these challenges and opportunities.

Buch. Condición: Neu. Neuware -Technology Commercialization: DEA and Related Analytical Methods for Evaluating The Use and Implementation of Technical Innovation examines both general Research & Development commercialization and targeted new product innovation. New product development is a major occupation of the technical sector of the global economy and is viewed in many ways as a means of economic stability for a business, an industry, and a country. The heart of the book is a detailing of the analytical methods-with special, but not exclusive emphasis on DEA methods-for evaluating and ranking the most promising R & D and technical innovation being developed. The sponsors of the research and development may involve universities, countries, industries, and corporations-all of these sources are covered in the book. In addition, the trade-off of environmental problems vis-à-vis new product development is discussed in a section of the book.Sten Thore (editor and author) has woven together the chapter contributions by a strong group of international researchers into a book that has characteristics of both a monograph and a unified edited volume of well-written papers in DEA, technology evaluation, R&D, and environmental economics. Finally, the use of DEA as an evaluation method for product innovation is an important new development in the field of R&D commercialization.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Buch. Condición: Neu. Neuware -Human activity overuses the resources of the planet at a rate that will severely compromise the ability of future generations to meet their needs. Changes toward sustainability need to begin within the next few years or environmental deterioration will become irreversible. Thus the need to develop a mindset of sustainable development - the ability of society to meet its needs without permanently compromising the earth's resources - is pressing.The Psychology of Sustainable Development clarifies the meaning of the term and describes the conditions necessary for it to occur. With contributions from an international team of policy shapers and makers, the book will be an important reference for environmental, developmental, social, and organizational psychologists, in addition to other social scientists concerned with the impact current human activity will have on the prospects of future generations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Buch. Condición: Neu. Neuware -Analog Filters, Second Edition covers four major fundamental types of analog filters - passive, op amp-RC, switched-capacitor, and operational transconductance amplifier-capacitor (OTA-C). (The last of these types is the major addition in the Second Edition). The emphasis is on the fundamental principles and theory of analog filters. It is targeted toward readers in telecommunications, signal processing, electronics, controls, instrumentation, bioengineering, etc. It introduces the reader to the elegant theory in the development of analog filters. Although some of the mechanical steps for generating filters are covered, the book stresses the mathematical bases and the scholastic ingenuity of analog filter theory. It should be helpful to nonspecialist electrical engineers to gain a background perspective and some basic insight to the development of real-time filters. In many modern advances in signal processing, their concepts and procedures have close links to analog filters. The material in this book will provide engineers with a better perspective and more penetrating appreciation of many modern signal-processing techniques.Also by Kendall Su: Handbook of Tables for Elliptic-Function Filters, ISBN 0-7923-9109-8.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Buch. Condición: Neu. Neuware - Towards collaborative business ecosystems Last decade was fertile in the emerging of new collaboration mechanisms and forms of dynamic virtual organizations, leading to the concept of dynamic business ecosystem, which is supported (or induced ) by the progress of the ubiquitous I pervasive computing and networking. The new technologies, collaborative business models, and organizational forms supported by networking tools 'invade' all traditional businesses and organizations what requires thinking in terms of whole systems, i. e. seeing each business as part of a wider economic ecosystem and environment. It is also becoming evident that the agile formation of very dynamic virtual organizations depends on the existence of a proper longer-term 'embedding' or 'nesting' environment (e. g. regional industry cluster), in order to guarantee certain basic requirements such as trust building ('Trusting your partner' is a gradual and long process); common interoperability, ontology, and distributed collaboration infrastructures; agreed business practices (requiring substantial engineering Ire-engineering efforts); a sense of community ('we vs. the others'), and some sense of stability (when is a dynamic state or a stationary state useful). The more frequent situation is the case in which this 'nesting' environment is formed by organizations located in a common region, although geography is not a major facet when cooperation is supported by computer networks.

Buch. Condición: Neu. Neuware - Massive traumatic stress resulting from armed conflict and terrorism is a prime concern of governments, non-government organizations and the United Nations. Yet there is little systematic knowledge of how to address psychological problems of these proportions. These situations are further complicated by the lack of culturally appropriate models for mental health care in many low-income countries. This volume describes a variety of public mental health and psychosocial programs in conflict and post-conflict situations in Africa and Asia. Each chapter details the psychosocial and mental health aspects of specific conflicts and examines them within their sociopolitical and historical contexts. Trauma, War, and Violence: Public Mental Health in Socio-Cultural Context will be of great interest to psychologists, social workers, anthropologists, historians, human rights experts, and psychiatrists working or interested in the field of psychotrauma.

Buch. Condición: Neu. Neuware - Optimization problems in practice are diverse and evolve over time, giving rise to - quirements both for ready-to-use optimization software packages and for optimization software libraries, which provide more or less adaptable building blocks for app- cation-specific software systems. In order to apply optimization methods to a new type of problem, corresponding models and algorithms have to be 'coded' so that they are accessible to a computer. One way to achieve this step is the use of a mod- ing language. Such modeling systems provide an excellent interface between models and solvers, but only for a limited range of model types (in some cases, for example, linear) due, in part, to limitations imposed by the solvers. Furthermore, while m- eling systems especially for heuristic search are an active research topic, it is still an open question as to whether such an approach may be generally successful. Modeling languages treat the solvers as a 'black box' with numerous controls. Due to variations, for example, with respect to the pursued objective or specific problem properties, - dressing real-world problems often requires special purpose methods. Thus, we are faced with the difficulty of efficiently adapting and applying appropriate methods to these problems. Optimization software libraries are intended to make it relatively easy and cost effective to incorporate advanced planning methods in application-specific software systems. A general classification provides a distinction between callable packages, nume- cal libraries, and component libraries.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although in nature the vast majority of polymers are condensation polymers, much publicity has been focused on functionalized vinyl polymers. Functional Condensation Polymers fulfills the need to explore these polymers which form an increasingly important and diverse foundation in the search for new materials in the twentyfirst century. Some of the advantages condensation polymers hold over vinyl polymers include offering different kinds of binding sites, their ability to be made biodegradable, and their different reactivities with various reagents under diverse reaction conditions. They also offer better tailoring of end-products, different tendencies (such as fiber formation), and different physical and chemical properties. Some of the main areas emphasized include dendrimers, control release of drugs, nanostructure materials, controlled biomedical recognition, and controllable electrolyte and electrical properties. 340 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In order to adapt the properties of living materials to their biological functions, nature has developed unique polyelectrolytes with outstanding physical, chemical and mechanical behavior. Namely polyampholytes can be suitable substances to model protein folding phenomenon and enzymatic activity most of biological macromolecules due to the presence of acidic and basic groups. The ability of linear and crosslinked amphoteric macromolecules to adopt globular, coil, helix and stretched conformations and to demonstrate coil-globule, helix-coil phase transitions, and sol-gel, collapsed expanded volume changes in relation to internal (nature and distribution of acid and base substituents, copolymer composition, hydrophobicity etc. ) and external (pH, temperature, ionic strength of the solution, thermodynamic quality of solvents etc. ) factors is very important and constantly attracts the attention of theorists and experimentalists because the hierarchy of amphoteric macromolecules can repeat, more or less, the structural organization of proteins. That is why polyampholytes fall within eyeshot of several disciplines, at least polymer chemistry and physics, molecular biology, colloid chemistry, coordination chemistry and catalysis. The main purpose of this monograph is to bridge the gap between synthetic and natural polymers and to show a closer relationship between two fascinating worlds. The first chapter of the book acquaints the readers with synthetic strategy of 'annealed', 'quenched' and 'zwitterionic' polyampholytes. Radical copolymerization, chemical modification and radiation-chemical polymerization methods are thoroughly considered. Kinetics and mechanism of formation of random, alternating, graft, di-block or tri-block sequences is discussed. The second chapterdeals with behavior of polyampholytes in solutions. 228 pp. Englisch.
