Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In recent years, considerable professional attention has centered on the behavioral aspects of various childhood illnesses and injuries. Indeed, child health psychology has grown exponentially over the past decade. One index of this growth is found in the number of texts that have recently appeared in the area (Gross & Drabman, 1990; Karoly, 1988; Krasnegor, Arasteh, & Cataldo, 1986; Levine, Carey, Crocker, & Gross, 1982; Routh, 1988; Russo & Varni, 1982; Tuma, 1982; Varni, 1983). In general, these texts provide summaries of the psychological literature across a variety of established (e.g., oncology) and emerging (psychoneuroimmunology) areas of child health. Until recently, many books on the psychological aspects of pediatric health provided no or minimal information about the psychosocial plight of child burn victims. In some instances, pediatric burns might be men tioned parenthetically as another example of a population for which behavioral treatment procedures (e. g., pain management) may be of value. In part, the relative inattention devoted to this population may be related to the perception that the literature in this area is sketchy and charac terized by significant methodological and substantive shortcomings. In many instances, this perception is largely justified. However, it is also the case that the pediatric burn literature has evolved considerably over the past decade and that the incidence of, and morbidity associated, with severe burn injuries mandates immediate and increased attention by mental health professionals. 308 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The general understanding of design is that it should lead to a manufacturable product. Neither the design nor the process of manufacturing is perfect. As a result, the product will be faulty, will require testing and fixing. Where does economics enter this scenario Consider the cost of testing and fixing the product. If a manufactured product is grossly faulty, or too many of the products are faulty, the cost of testing and fixing will be high. Suppose we do not like that. We then ask what is the cause of the faulty product. There must be something wrong in the manufacturing process. We trace this cause and fix it. Suppose we fix all possible causes and have no defective products. We would have eliminated the need for testing. Unfortunately, things are not so perfect. There is a cost involved with finding and eliminating the causes of faults. We thus have two costs: the cost of testing and fixing (we will call it cost-1), and the cost of finding and eliminating causes of faults (call it cost-2). Both costs, in some way, are included in the overall cost of the product. If we try to eliminate cost-1, cost-2 goes up, and vice versa. An economic system of production will minimize the overall cost of the product. Economics of Electronic Design, Manufacture and Test is a collection of research contributions derived from the Second Workshop on Economics of Design, Manufacture and Test, written for inclusion in this book. 196 pp. Englisch.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with microwave electronics, that is to say those components of microwave circuits that generate, amplify, detect or modulate signals. It is based on a course given in the Electrical Engineering Department of Eindhoven University since 1985 and on about twenty years of experience in the microwave field. Somewhat to my surprise I found that there were hardly any textbooks that addressed the specific properties and demands of microwave devices, including vacuum devices and their interactions with circuits. Numerous books exist on semiconductor electronic devices, dealing in an excellent way with the basic device physics, but being somewhat brief on typical micro wave aspects. On the other hand there are also many books that concentrate on electromagnetic theory and passive circuits, treating devices without reference to the underlying physics. In between there are some entirely devoted to a particular device, for example, the GaAs MESFET. With regard to tubes the situation is even worse: books that treat the basic principles are usually quite old and modern books often concentrate on specific devices, like high power tubes. So it seems that there is room for a book like this one. Its aim is to provide an elementary understanding ofmicrowave electronic devices, both vacuum and semiconductor, on the one hand in relation to the basic physics underlying their operation and on the other in relation to their circuit applications. 360 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This work results from my interest in the field of vector optimiza tion. I stumbled first upon this subject in 1982 during my six months visit to the Istituto di Elaborazione della Informazione in Pisa, Italy, supported by a fellowship of the (Italian) Consiglio Nationale delle Richerche. I was attracted then by a gap between vector optimiza tion used to serve as a formal model for multiple objective decision problems and the decision problems themselves, the gap nonexis tent in scalar optimization. Roughly speaking, vector optimization provides methods for ranking decisions according to a partial order whereas decision making requires a linear ordering of decisions. The book deals with vector optimization. However, vector opti mization is considered here not only as a topic of research in itself but also as a basic tool for decision making. In consequence, all results presented here are aimed at exploiting and understanding the structure of elements (decisions) framed by a vector optimiza tion problem with the underlying assumption that the results should be interpretable in terms and applicable in the context of decision making. Computational tractability of results is therefore of special concern throughout this book. A unified framework for presentation is offered by the Cone Sep aration Technique (CST) founded on the notion of cone separation. 180 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Neural network and artificial intelligence algorithrns and computing have increased not only in complexity but also in the number of applications. This in turn has posed a tremendous need for a larger computational power that conventional scalar processors may not be able to deliver efficiently. These processors are oriented towards numeric and data manipulations. Due to the neurocomputing requirements (such as non-programming and learning) and the artificial intelligence requirements (such as symbolic manipulation and knowledge representation) a different set of constraints and demands are imposed on the computer architectures/organizations for these applications. Research and development of new computer architectures and VLSI circuits for neural networks and artificial intelligence have been increased in order to meet the new performance requirements. This book presents novel approaches and trends on VLSI implementations of machines for these applications. Papers have been drawn from a number of research communities; the subjects span analog and digital VLSI design, computer design, computer architectures, neurocomputing and artificial intelligence techniques. This book has been organized into four subject areas that cover the two major categories of this book; the areas are: analog circuits for neural networks, digital implementations of neural networks, neural networks on multiprocessor systems and applications, and VLSI machines for artificial intelligence. The topics that are covered in each area are briefly introduced below. 336 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A fundamental assumption of work in artificial intelligence and machine learning is that knowledge is expressed in a computer with the help of knowledge representations. Since the proper choice of such representations is a difficult task that fundamentally affects the capabilities of a system, the problem of automatic representation change is an important topic in current research. Concept Formation and Knowledge Revision focuses on representation change as a concept formation task, regarding concepts as the elementary representational vocabulary from which further statements are constructed. Taking an interdisciplinary approach from psychological foundations to computer implementations, the book draws on existing psychological results about the nature of human concepts and concept formation to determine the scope of concept formation phenomena, and to identify potential components of computational concept formation models. The central idea of this work is that computational concept formation can usefully be understood as a process that is triggered in a demand-driven fashion by the representational needs of the learning system, and identify the knowledge revision activities of a system as a particular context for such a process. The book presents a detailed analysis of the revision problem for first-order clausal theories, and develops a set of postulates that any such operation should satisfy. It shows how a minimum theory revision operator can be realized by using exception sets, and that this operator is indeed maximally general. The book then shows that concept formation can be triggered from within the knowledge revision process whenever the existing representation does not permit the plausible reformulation of an exception set, demonstrating the usefulness of the approach both theoretically and empirically within the learning knowledge acquisition system MOBAL. In using a first-order representation, this book is part of the rapidly developing field of Inductive Logic Programming (ILP). By integrating the computational issues with psychological and fundamental discussions of concept formation phenomena, the book will be of interest to readers both theoretically and psychologically inclined. From the foreword by Katharina Morik: ` The ideal to combine the three sources of artificial intelligence research has almost never been reached. Such a combined and integrated research requires the researcher to master different ways of thinking, different work styles, different sets of literature, and different research procedures. It requires capabilities in software engineering for the application part, in theoretical computer science for the theory part, and in psychology for the cognitive part. The most important capability for artificial intelligence is to keep the integrative view and to create a true original work that goes beyond the collection of pieces from different fields. This book achieves such an integrative view of concept formation and knowledge revision by presenting the way from psychological investigations that indicate that concepts are theories and point at the important role of a demand for learning. to an implemented system which supports users in their tasks when working with a knowledge base and its theoretical foundation.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Foundations of Dependable Computing: Paradigms for Dependable Applications, presents a variety of specific approaches to achieving dependability at the application level. Driven by the higher level fault models of Models and Frameworks for Dependable Systems, and built on the lower level abstractions implemented in a third companion book subtitled System Implementation, these approaches demonstrate how dependability may be tuned to the requirements of an application, the fault environment, and the characteristics of the target platform. Three classes of paradigms are considered: protocol-based paradigms for distributed applications, algorithm-based paradigms for parallel applications, and approaches to exploiting application semantics in embedded real-time control systems. The companion volume subtitled Models and Frameworks for Dependable Systems presents two comprehensive frameworks for reasoning about system dependability, thereby establishing a context for understanding the roles played by specific approaches presented in this book's two companion volumes. It then explores the range of models and analysis methods necessary to design, validate and analyze dependable systems. Another companion book (published by Kluwer) subtitled System Implementation, explores the system infrastructure needed to support the various paradigms of Paradigms for Dependable Applications. Approaches to implementing support mechanisms and to incorporating additional appropriate levels of fault detection and fault tolerance at the processor, network, and operating system level are presented. A primary concern at these levels is balancing cost and performance against coverage and overall dependability. As these chapters demonstrate, low overhead, practical solutions are attainable and not necessarily incompatible with performance considerations. The section on innovative compiler support, in particular, demonstrates how the benefits of application specificity may be obtained while reducing hardware cost and run-time overhead. 232 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The NATO Advanced Research Workshop on Coherent Optical Processes in Semiconductors was held in Cambridge, England on August 11-14,1993. The idea of holding this Workshop grew from the recent upsurge in activity on coherent transient effects in semiconductors. The development of this field reflects advances in both light sources and the quality of semiconductor structures, such that tunable optical pulses are now routinely available whose duration is shorter than the dephasing time for excitonic states in quantum wells. It was therefore no surprise to the organisers that as the programme developed, there emerged a heavy emphasis on time-resolved four-wave mixing, particularly in quantum wells. Nevertheless, other issues concerned with coherent effects ensured that several papers on related problems contributed some variety. The topics discussed at the workshop centred on what is a rather new field of study, and benefited enormously by having participants representing many of the principal groups working in this area. Several themes emerged through the invited contributions at the Workshop. One important development has been the careful examination of the two-level model of excitonic effects; a model which has been remarkably successful despite the expected complexities arising from the semiconductor band structure. Indeed, modest extensions to the two level model have been able to offer a useful account for some of the complicated polarisation dependence of four-wave mixing signals from GaAs quantum wells. This work clearly is leading to an improved understanding of excitons in confined systems. 388 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Image segmentation is generally the first task in any automated image understanding application, such as autonomous vehicle navigation, object recognition, photointerpretation, etc. All subsequent tasks, such as feature extraction, object detection, and object recognition, rely heavily on the quality of segmentation. One of the fundamental weaknesses of current image segmentation algorithms is their inability to adapt the segmentation process as real-world changes are reflected in the image. Only after numerous modifications to an algorithm's control parameters can any current image segmentation technique be used to handle the diversity of images encountered in real-world applications. Genetic Learning for Adaptive Image Segmentation presents the first closed-loop image segmentation system that incorporates genetic and other algorithms to adapt the segmentation process to changes in image characteristics caused by variable environmental conditions, such as time of day, time of year, weather, etc. Image segmentation performance is evaluated using multiple measures of segmentation quality. These quality measures include global characteristics of the entire image as well as local features of individual object regions in the image. This adaptive image segmentation system provides continuous adaptation to normal environmental variations, exhibits learning capabilities, and provides robust performance when interacting with a dynamic environment. This research is directed towards adapting the performance of a well known existing segmentation algorithm (Phoenix) across a wide variety of environmental conditions which cause changes in the image characteristics. The book presents a large number of experimental results and compares performance with standard techniques used in computer vision for both consistency and quality of segmentation results. These results demonstrate, (a) the ability to adapt the segmentation performance in both indoor and outdoor color imagery, and (b) that learning from experience can be used to improve the segmentation performance over time. 300 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The recent developments in modern vaccinology are mainly based on: (i) cloning of microbial genes into recombinant vectors containing genetic information for expression of desired neutralizing immunogens; (ii) alternatives of attenuated vectors with deleted genes permitting the insertion of several foreign genes expressing antigens exposed to the host immune system during the abortive replication of such vectors; (iii) combined vaccines with the aim to protect against many diseases with a limited number of administrations; (iv) evidence demonstrating the ability of animals to respond serologically to DNA injections considered as a potential method of vaccination; (v) the possibility to manipulate the immune system with new and improved immunomodulators enhancing the immune response; and (vi) new microcarrier systems for particular immunogens or immunomodulators delivery, either in a single dose or sustained release, and presentation to the immune system for a relevant response. New vaccines being developed are mainly based on viral, bacterial or other vectors modified with genetic engineering technology, to possess and express desired antigens for vaccination against single or multiple infections. Existing combined vaccines like diphtheria, tetanus, pertussis (DTP) are also experimented with new additional components like recombinant hepatitis B virus surface antigen, inactivated poliovirus, and Haemophilus inJluenzae type b immunogens, in order to produce multivalent vaccines. Such types of vaccines permitting the reduction of multiple medical visits is of particular interest to pediatric immuni zation programs, and would benefit especially the developing countries assuring better vaccine compliance with immunization schedules. 412 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The recent series of texts 'Developments in Food Proteins' comprised in all seven volumes which were published in the course of the decade 1982-1991. Each volume contained inter alia one or more chapters that were concerned with new or developing sources of food proteins. Most of these have now been collected together in an up dated and re-evaluated form for the present volume. 'New' sources of food proteins includes those sources that are unconventional, that are still of very limited significance in market terms, or that are at present of very localized use. Several of these were included in 'Developments in Food Proteins'. One of them, algae, appeared both in Volume 1 and in an up-dated form in Volume 7. It is therefore not included here. Others, such as yeasts and bacteria, have not yet increased in practical importance as potential food components beyond the long-term promise already evident at that time. However, leaf protein, as described in the present Chapter 10, has moved from the original rather crude concept to a much more sophisticated product in the form of Rubisco. Fungal protein, as Quorn (Chapter 11), has also proved to be potentially of real food value. 'Developing' sources of food protein are those sources that have always been basic items in human diets. 388 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Multithreaded computer architecture has emerged as one of the most promising and exciting avenues for the exploitation of parallelism. This new field represents the confluence of several independent research directions which have united over a common set of issues and techniques. Multithreading draws on recent advances in dataflow, RISC, compiling for fine-grained parallel execution, and dynamic resource management. It offers the hope of dramatic performance increases through parallel execution for a broad spectrum of significant applications based on extensions to `traditional' approaches. Multithreaded Computer Architecture is divided into four parts, reflecting four major perspectives on the topic. Part I provides the reader with basic background information, definitions, and surveys of work which have in one way or another been pivotal in defining and shaping multithreading as an architectural discipline. Part II examines key elements of multithreading, highlighting the fundamental nature of latency and synchronization. This section presents clever techniques for hiding latency and supporting large synchronization name spaces. Part III looks at three major multithreaded systems, considering issues of machine organization and compilation strategy. Part IV concludes the volume with an analysis of multithreaded architectures, showcasing methodologies and actual measurements. Multithreaded Computer Architecture: A Summary of the State of the Art is an excellent reference source and may be used as a text for advanced courses on the subject. 420 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Nonlinear dynamical systems play an important role in a number of disciplines. The physical, biological, economic and even sociological worlds are comprised of com plex nonlinear systems that cannot be broken down into the behavior of their con stituents and then reassembled to form the whole. The lack of a superposition principle in such systems has challenged researchers to use a variety of analytic and numerical methods in attempts to understand the interesting nonlinear interactions that occur in the World around us. General relativity is a nonlinear dynamical theory par excellence. Only recently has the nonlinear evolution of the gravitational field described by the theory been tackled through the use of methods used in other disciplines to study the importance of time dependent nonlinearities. The complexity of the equations of general relativity has been (and still remains) a major hurdle in the formulation of concrete mathematical concepts. In the past the imposition of a high degree of symmetry has allowed the construction of exact solutions to the Einstein equations. However, most of those solutions are nonphysical and of those that do have a physical significance, many are often highly idealized or time independent. 488 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Turbulence takes place in most flow situations whethertheyoccur naturally or in technological systems. Therefore, considerable effort is being expended in an attempt to understand the phenomenon of turbulence. The recent discovery ofcoherent structure in turbulent shear flows and the modem developments in computer capabilities have revolutionized research work in turbulence. There is a strong evidence that the coherent structure in turbulent shear flows is reminiscent of nonlinear stability waves. As such, the interest in nonlinear stability waves has increased not only for the understandingofthe latterstages of the laminar-turbulent transition process, but also for understanding the coherent structures in turbulent flows. Also. the advances in computers have made direct numerical simulation possible at Low-Reynolds numbers and large-eddy simulation possible at high Reynolds numbers. This made first-principles prediction of turbulence-generated noise feasible. Therefore, this book aims at presenting a graduate-level introductory study of turbulence while accounting for such recent views of concern to researchers. This book is an outgrowth oflecture notes on the subject offered to graduate students in engineering. The book should be of interest to research engineers and graduatestudents in science and engineering. The theoretical basis presented is sufficient not only for studying the specialized literature on turbulence but also for theoretical investigations on the subject. 400 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -High temperature superconductivity (HTSC) hast he potential todramatically impact many commercial markets, including the electric power industry. Since 1987, the Electric Power Research Institute (EPRI) has supported aprogram to develop HTSC applications fort he power industry. The purpose ofEPRI is to manage technical research and development programs to improve power production, distribution, and use. The institute is supported by the voluntary contributions ofs ome7 00 electric utilities and has over 600 utility technical experts as advisors. One objectiveo f EPRI s HTSC program is to ed ucate utility engineers andexecutives on the technical issues related to HTSC materials and the supporting technologies needed for their application. To accomplish this, Argonne National Laboratory was commissioned to preparea series of monthly re ports that would explain th e significanceo f recent advances in HTSC. Acomponent o f each report was a tutorial on some aspect of the HTSC field. Topics ranged from the various ways that thin films are deposited tot he mechanisms used to operatem ajor cryogenic systems. The tutorials became very popularw ithin the utility industry. Surprisingly, the reports also became popular with scientists at universities, corporate labo ratories, and thenational laboratories. A lthough these researchers are quite experienced in one aspect of the technology, they are nots ostron g inothers. Itw ast he diversity and thoroughness ofthe tutorials that made them so valuable. 604 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Almost every aspect of energy and nutrient metabolism is altered by hormonal and other physiological changes during pregnancy and lactation. While it is evident that hormonal adjustments affect nutrient requirements, these are rarely considered when nutrient recommen dations are made for pregnant or lactating women, and often neglected during evaluation of nutritional status. In addition, changes in nutrient metabolism during the stages of pregnancy and oflactation are usually considered separately, while in reality events during pregnancy can have a major influence on nutritional status and nutrient requirements during lactation. The purpose of this volume is to describe changes in the metabolism of important nutrients during pregnancy and lactation, including the physiological basis for these changes and their implications for nutrient requirements and assessment. Authors have considered such issues as inter-relationships between endocrine changes and nutrient metabolism at the tissue, cellular and molecular level; alterations in nutrient binding proteins; the efficiency of nutrient absorp tion and retention; and the impact on maternal as well as fetal nutritional status. Another unique aspect of this book is the focus on pregnancy and lactation as a continuum. 316 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A number of factors have come together in the last couple of decades to define the emerging interdisciplinary field of structural molecular biology. First, there has been the considerable growth in our ability to obtain atomic-resolution structural data for biological molecules in general, and proteins in particular. This is a result of advances in technique, both in x-ray crystallography, driven by the development of electronic detectors and of synchrotron radiation x-ray sources, and by the development ofNMR techniques which allow for inference of a three-dimensional structure of a protein in solution. Second, there has been the enormous development of techniques in DNA engineering which makes it possible to isolate and clone specific molecules of interest in sufficient quantities to enable structural measurements. In addition, the ability to mutate a given amino acid sequence at will has led to a new branch of biochemistry in which quantitative measurements can be made assessing the influence of a given amino acid on the function of a biological molecule. A third factor, resulting from the exponential increase in computing power available to researchers, has been the emergence of a growing body of people who can take the structural data and use it to build atomic-scale models of biomolecules in order to try and simulate their motions in an aqueous environment, thus helping to provide answers to one of the most basic questions of molecular biology: the relation of structure to function. 420 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this NATO Advanced Study Institute was to bring together scientists and students working in the field of laser matter interactions in order to review and stimulate developmentoffundamental science with ultra-short pulse lasers. New techniques of pulse compression and colliding-pulse mode-locking have made possible the construction of lasers with pulse lengths in the femtosecond range. Such lasers are now in operation at several research laboratories in Europe and the United States. These laser facilities present a new and exciting research direction with both pure and applied science components. In this ASI the emphasis is on fundamental processes occurring in the interaction of short laser pulses with atoms, molecules, solids, and plasmas. In the case of laser-atom (molecule) interactions, high power lasers provide the first access to extreme high-intensity conditions above 10'8 Watts/em', a new frontier for nonlinear interaction of photons with atoms and molecules. New phenomena observed include multiphoton ionization processes, atomic collisions in the presence of a strong laser field, Coulomb explosion following rapid ionization of a molecule and the production of high harmonics of the laser source. Another important topic reviewed in this ASI is the lasercooling ofatoms. 488 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the past fifteen years commercial interest in compounds containing carbon fluorine bonds has burgeoned beyond all expectations, mainly owing to business opportunities arising from work on biologically active fluoroorganics-particularly agrochemicals, the relentless search for new markets for fluoropolymers and fluoro carbon fluids, developments in the field of medical diagnostics, and the drive to find replacements for ozone-depleting CFCs and Halon fire-extinguishing agents. Judging the situation to warrant the publication of a comprehensive collection of up-to-date reviews dealing with commercial organofluorine compounds within a single volume of manageable size (and hence reasonable cost), we were delighted to be invited by Plenum Publishing Corporation to produce a suitable book. In order to provide an authentic and wide-ranging account of current commercial applications of fluoroorganic materials, it clearly was necessary to assemble a sizeable team of knowledgeable contributing authors selected almost entirely from industry. Through their efforts we have been able to produce an almost complete coverage of the modem organofluorochemicals business in a manner designed to attract a reader ship ranging from experts in the field, through chemists and technologists currently unaware of the extent of industrial involvement with fluoroorganics, to students of applied chemistry. Promised chapters dedicated to perfluoroolefin oxides and 18F labeling of radiopharmaceuticals failed to materialize. This is somewhat unfortunate in view of our aim to achieve comprehensive coverage of the subject. 674 pp. Englisch.
