Buch. Condizione: Neu. Neuware - In this volume, designed for engineers and scientists working in the area of Computational Fluid Dynamics (CFD), experts offer assessments of the capabilities of CFD, highlight some fundamental issues and barriers, and propose novel approaches to overcome these problems. They also offer new avenues for research in traditional and non-traditional disciplines. The scope of the papers ranges from the scholarly to the practical. This book is distinguished from earlier surveys by its emphasis on the problems facing CFD and by its focus on non-traditional applications of CFD techniques. There have been several significant developments in CFD since the last workshop held in 1990 and this book brings together the key developments in a single unified volume.

Taschenbuch. Condizione: Neu. Neuware - This book and CD-ROM package has been developed in a lab-oriented course taught at Cal Tech in 1995 and 1996, and simultaneously augmented by artificial life research conducted there. These courses were attended by an interdisciplinary group of students from physics, computer science, and the computational neural sciences. The authors assume a pre-requisite understanding of statistical physics and thermodynamics, basic biology, as well as familiarity with computer architectures and scientific computing techniques. This project brings together the necessary theoretical groundwork for understanding the dynamics of systems of self-replicating information, as well as the results of initial experiments carried out with artificial living systems based on this paradigm.

Taschenbuch. Condizione: Neu. Neuware - Once again, in their new edition of a classic American handbook of clinical psycho pharmacology, Drs. Gelenberg and Bassuk and their colleagues have produced a master work of sound clinical guidelines for the use of medicines as an increasingly central component of contemporary psychiatric practice. They have recruited an outstanding panel of coauthors, but have managed to maintain a high level of consistency of quality and style throughout the many chapters on specific classes of psychiatric illnesses and their corresponding treatments. The book continues to encapsulate the clinically rele vant essentials of the pharmacology of each major class of psychotropic agents in a way that clinicians can easily grasp. Moreover, it provides sound and carefully consid ered specific guidelines to diagnosis, drug selection, and dosing and patient assessment, with particularly rich presentations on the recognition and management of adverse effects. Inclusion of chapters on pediatric and geriatric populations and on topics pertaining to substance abuse disorders and medicolegal aspects of the field are unusual in books of this kind, and so are particularly valuable. Students and trainees will appreciate the handbook's well-organized and readable style, and practicing clinicans should be satisified with its balanced consideration of older, standard treatments as well as the latest medicines and trends in clinical psychopharmacology, with glimpses into future developments.

Buch. Condizione: Neu. Neuware - Based on the results of the study carried out in 1996 to investigate the state of the art of workflow and process technology, MCC initiated the Collaboration Management Infrastructure (CMI) research project to develop innovative agent-based process technology that can support the process requirements of dynamically changing organizations and the requirements of nomadic computing. With a research focus on the flow of interaction among people and software agents representing people, the project deliverables will include a scalable, heterogeneous, ubiquitous and nomadic infrastructure for business processes. The resulting technology is being tested in applications that stress an intensive mobile collaboration among people as part of large, evolving business processes. Workflow and Process Automation: Concepts and Technology provides an overview of the problems and issues related to process and workflow technology, and in particular to definition and analysis of processes and workflows, and execution of their instances. The need for a transactional workflow model is discussed and a spectrum of related transaction models is covered in detail. A plethora of influential projects in workflow and process automation is summarized. The projects are drawn from both academia and industry. The monograph also provides a short overview of the most popular workflow management products, and the state of the workflow industry in general. Workflow and Process Automation: Concepts and Technology offers a road map through the shortcomings of existing solutions of process improvement by people with daily first-hand experience, and is suitable as a secondary text for graduate-level courses on workflow and process automation, and as a reference for practitioners in industry.

Buch. Condizione: Neu. Neuware - The objective of this book is to provide the researcher and clinician with the recent developments in the analysis and assessment of cardiovascular func tion. The chapters are organized into sections that correspond with the various anatomical levels of the cardiovascular system. To a large extent, recent focus on the cardiovascular system function has been directed at the molecular level to the near exclusion of the tissue and organ function. While this may be useful in developing new therapeutic drugs, it does not aid the cardiologist or surgeon, who routinely deal with patient symptoms. This book integrates the micro-level and organ-level function so that new infor mation may be assimilated into the cardiovascular system as a whole. Within each section, the chapters have been arranged to progress from recent theoretical developments, to experimental research, and finally to clinical applications. This approach facilitates the timely transfer of infor mation from basic research to the clinic. The strength of the analytical approach will be evident to the reader. The theoretical analysis offers guidance to experimental design and, in some cases, offers solutions where measurements are as yet unattainable. In moving from newly attained knowledge to clinical practice, this book emphasizes the noninvasive meth in the future as technological advances ods. Such methods are desirable occur and the trend towards early preventive diagnosis is sought. What follows are highlights of new developments covered in each section of the book.

Buch. Condizione: Neu. Neuware - This book is a collection of articles on Japanese grammars written in a framework broadly construed as constraint-based. Having evolved from a progress report on the Japanese phrase structure grammar (JPSG) project, it implements ideas from recent developments in phrase structure grammar formalism, such as head-drive phrase structure grammar (HPSG). Part I gives an overview of JPSG, introducing fundamental assumptions and discussing mostly syntactic and semantic aspects of Japanese in the constraint-based formalism, as well as the implementation of a parser based on the grammar. The papers in Part II discuss mostly pragmatic aspects of Japanese. Innovative concepts are introduced in Part I, such as the concept of cost, which plays a central role both in the treatment of quantifiers and phonology, and is used extensively in the treatment of conditionals in Part II. Stress is also placed on the role of discourse participants; the analysis of relativization adopted in Part I is partly based on zero pronominals, whose interpretation is left to pragmatics. This issue is further pursued in Part II and may serve as one possible avenue to explore pragmatics.

Buch. Condizione: Neu. Neuware - This volume offers one of the first systematic analyses of the rise of modern social science. Contrary to the standard accounts of various social science disciplines, the essays in this volume demonstrate that modern social science actually emerged during the critical period between 1750 and 1850. It is shown that the social sciences were a crucial element in the conceptual and epistemic revolution, which parallelled and partly underpinned the political and economic transformations of the modern world. From a consistently comparative perspective, a group of internationally leading scholars takes up fundamental issues such as the role of the Enlightenment and the French Revolution in the shaping of the social sciences, the changing relationships between political theory and moral discourse, the profound transformation of philosophy, and the constitution of political economy and statistics.

Microprocessors and computers used to be the main limiting element in most information processing systems. But thanks to the enonnous progress in the microelectronics industry, most information analysis tasks can be processed in real time. The data has to be acquired by the processor in some form and processed and used to produce some useful function in the real world.

Buch. Condizione: Neu. Neuware - Designers of wireless networks face a problem which is multidimensional in nature, where issues of multiaccess, radio propagation, antennas, mobility and teletraffic all need to be understood and simultaneously addressed in order to create a properly functioning system. This book does not merely concentrate on one of these issues but takes a broader view, and presents a mix of papers addressing systems and networking issues. Multiaccess, Mobility and Teletraffic: Advances in Wireless Networks addresses fundamental theoretical issues about future wireless networks, such as capacity improvements theoretically attainable from spread spectrum systems, and practical concerns associated with current networks such as signalling, implementation of GSM and CDMA networks, and implementation of packet data services over wireless networks. As well as the papers looking at specific technologies, this book contains a number of papers discussing more generic problems in mobile networks, such as issues associated with handoff, resource management, frequency reuse, mobility, signalling and wireless packet networks. Multiaccess, Mobility and Teletraffic: Advances in Wireless Networks covers a broad range of issues associated with wireless networks and provides a very interesting snapshot of the current state-of-the-art. It will be of interest to all researchers and practitioners working in the field of wireless communications and networks.

Buch. Condizione: Neu. Neuware - Constraints and Databases contains seven contributions on the rapidly evolving research area of constraints and databases. This collection of original research articles has been compiled as a tribute to Paris C. Kanellakis, one of the pioneers in the field. Constraints have long been used for maintaining the integrity of databases. More recently, constraint databases have emerged where databases store and manipulate data in the form of constraints. The generality of constraint databases makes them highly attractive for many applications. Constraints provide a uniform mechanism for describing heterogenous data, and advanced constraint solving methods can be used for efficient manipulation of constraint data. The articles included in this book cover the range of topics involving constraints and databases; join algorithms, evaluation methods, applications (e.g. data mining) and implementations of constraint databases, as well as more traditional topics such as integrity constraint maintenance. Constraints and Databases is an edited volume of original research comprising invited contributions by leading researchers.

Buch. Condizione: Neu. Neuware - 1 1. 1 Introduction The (signal processing and storage) capacity ofthe human brain enables us to become powerful autonomous beings, but only if our brains operate in conjunction with (at least some of) our senses and muscles. Using these organs, we can interact with our environment, learn to adapt, and improve important aspects of our life. Similarly, the signal processing capabilities of modern electronics (computers) could be combined with electronic sensors and actuators to enable interaction with, and adaptation to, the (non-electrical) environment. This willlead to smarter and more powerful automated tools and machines. To facilitate and stimulate such a development, easy-to-use low-cost sensors are needed. The combination of electronic interface functions and a sensor in an integrated smart sensor, that provides a standard, digital, and bus-compatible output, would simplify the connection of sensors to standard electronic signal processors (microcontrollers, computers, etc. ). Currently, the calibration procedure, required for standardization of the sensor output signal level, contributes largely to the production costs of accurate sensors. To enable automation of the calibration procedure, and hence reduce the sensor fabrication costs, a digital calibrationjunction should be included in the smart sensor. INTEGRATED SMART SENSORS: Design and Calibration Introduction 1. 2 Sensors and actuators In industry many processes are electronically controlled. As depicted in Fig.

Buch. Condizione: Neu. Neuware - Transaction Management Support for Cooperative Application is a comprehensive report on a successful international project, called TRANSCOOP, carried out from 1994 to 1997 by a group of European scientists. But the book is also much more than that, namely, an ambitious attempt to integrate Computer-Supported Cooperative Work (CSCW), Workflow Management Systems (WFMS), and Transaction Processing (TP) technologies. The very term {em cooperative transactions} is in itself contradictory. Cooperation technologies, such as CSCW, aim at providing a framework for information exchange between cooperating (human) participants. In contrast, traditional transaction technologies allow concurrent users to operate on shared data, while providing them with the illusion of complete isolation from each other. To overcome this contradiction, the TRANSCOOP researchers had to come up with a new and original notion of correctness of concurrent executions, based on controlled exchange of information between concurrent users. Merging histories in accordance with prespecified commutativity rules among concurrent operations provides transactional guarantees to activities such as cooperative designing, which until now had to be carried out sequentially. As an interesting consequence, it also provides a basis for management of consistency between disconnected or mobile users who operate independently and yet, must occasionally reconcile their work with each other.

Buch. Condizione: Neu. Neuware - The purpose of this book is to provide a balanced introduction to process control and management, aimed at the general process engineer. Rapid changes have occurred in process control over the past decade, mainly because of the deployment of robust and effective digital control equipment, and the development of the models which underpin the area. Historically, process control was seen as simply the maintenance of particular process variables at appropriate setpoints. This very narrow view has been superseded by the view that process control involves the regulation of any given process, in the context of a complete processing plant, to maximise the economic return from the plant. This wider definition brings into play a range of control regimes, from basic regulatory control, through advanced regulatory control, to complex process management. The organization of the book reflects this hierarchy, and is thus split into 3 parts, covering basic regulatory control, advanced process control and finally process management. The book is completed by the inclusion of several useful appendices, covering mathematical modelling, process optimisation and simulation.

Buch. Condizione: Neu. Neuware - Researchers working with nonlinear programming often claim 'the word is non linear' indicating that real applications require nonlinear modeling. The same is true for other areas such as multi-objective programming (there are always several goals in a real application), stochastic programming (all data is uncer tain and therefore stochastic models should be used), and so forth. In this spirit we claim: The word is multilevel. In many decision processes there is a hierarchy of decision makers, and decisions are made at different levels in this hierarchy. One way to handle such hierar chies is to focus on one level and include other levels' behaviors as assumptions. Multilevel programming is the research area that focuses on the whole hierar chy structure. In terms of modeling, the constraint domain associated with a multilevel programming problem is implicitly determined by a series of opti mization problems which must be solved in a predetermined sequence. If only two levels are considered, we have one leader (associated with the upper level) and one follower (associated with the lower level).

Buch. Condizione: Neu. Neuware - This book provides a detailed, wide ranging and up-to-date review of all aspects of the chemistry of the elements arsenic, antimony and bismuth. The chapters are written by an international team of authors each of whom is both active and expert in their particular field. The coverage includes chapters on general properties and periodicity, the elements themselves, inorganic derivatives of the elements, co-ordination and solution chemistry, organocompounds, organotransition metal compounds, environmental and medicinal aspects and analytical methods. This volume will be of particular value to graduate and postgraduate chemists and materials scientists in both industry and academia who are concerned with any aspect of the chemistry of these three elements and will also be an essential addition to the reference section of any chemistry library.

Buch. Condizione: Neu. Neuware - Nonconvexity and nonsmoothness arise in a large class of engineering applica tions. In many cases of practical importance the possibilities offered by opti mization with its algorithms and heuristics can substantially improve the per formance and the range of applicability of classical computational mechanics algorithms. For a class of problems this approach is the only one that really works. The present book presents in a comprehensive way the application of opti mization algorithms and heuristics in smooth and nonsmooth mechanics. The necessity of this approach is presented to the reader through simple, represen tative examples. As things become more complex, the necessary material from convex and nonconvex optimization and from mechanics are introduced in a self-contained way. Unilateral contact and friction problems, adhesive contact and delamination problems, nonconvex elastoplasticity, fractal friction laws, frames with semi rigid connections, are among the applications which are treated in details here. Working algorithms are given for each application and are demonstrated by means of representative examples. The interested reader will find helpful references to up-to-date scientific and technical literature so that to be able to work on research or engineering topics which are not directly covered here.

Buch. Condizione: Neu. Neuware - Self-individualization has been interpreted as the process in which the all-embracing Self unfolds into an infinite variety of different individ uals, plants, animals and men. A comparison of the different ways in which the Self manifests itself in the biological and psychological devel opmental processes, or in a visionary image of the undivided Self, reveals the same basic structure of expression. The Self, the one, is represented by a circular domain, and comprises a basic inner duality, the two, creating a paradox of conflicting opposites. In the undivided Self the two give rise to a trinity in which, however, a quatemity is hidden. The latter expresses itself in this world as the four basic forces, the four Elements or the four main archetypes, specifying the possibilities or development in space and time. Self-individualization starts with the first appearance of a primary structure of an individual sub-Self. This is the fifth basic force, the fifth Element. Further development is character ized by four generative principles: 1st, the principle of wholeness: connection and integration (being oriented to remaining whole or restoring wholeness); 2nd, the principle of complementarity and com pensation (a periodic shift between opposing influences); 3rd, the enstructuring principle (causing the relative stability of the spatial appear ance of the manifest structure), and 4th, the principle of gesture (resulting in a gradual stepwise development of that structure into a full-grown individual).

Buch. Condizione: Neu. Neuware - The chemistry and biochemistry of carbohydrates have become key research areas throughout the world. Responding to the enormous interest expressed in these fields, this new book has brought together a range of contributors, each working at the forefront of carbohydrate chemistry and biochemistry to provide concise authoritative and timely review of these exciting areas. Aimed at chemists, biochemists and biologists, the reader will find this book an invaluable introduction to and review of the most important developments in carbohydrate chemistry. As a distinct chemical group, the carbohydrates comprising mono-, oligo-, and polysaccharides and their derivatives are the most abundant group of natural products. From simple monosaccharides produced in photosynthesis to polysaccharides built in complex biochemical reactions, carbohydrates are produced in huge quantities by plant and animal life. Apart from dietary and structural uses in plants and animals, it is now well established that carbohydrates play a number of key roles in living systems. From cell-cell recognition to hormonal activities, carbohydrates are implicated in a wide range of cellular processes. This new understanding has forced the study of carbohydrates to the forefront of modern chemical research. For example, the nature of the role of carbohydrates in living systems offers the potential to provide important lead compounds in the development of new bioactive molecules. Similarly, the relative abundance of carbohydrates is prompting research aimed at utilizing simple monosaccharides as starting materials for a range of high value chemical product, offering a renewable alternative to current starting materials.

Buch. Condizione: Neu. Neuware - Polymer network materials are widespread in their occurrence and find many applications in the exploitation of polymer systems. The characteristic separating a network material from a conventional polymer is a molecular structure which permeates the whole sample. This structure may be the result of covalent linking of molecules, or a physical association of simple molecules, but whichever is present the properties are strongly influenced by the formation of a network. As the network formed is itself influenced strongly by the method and conditions of preparation it follows that in comparison with simple linear polymers, the properties of the final network polymer are much more influenced by preparative variables. Written by an international team of authors, with a strong emphasis on the underlying chemistry, this book forms a timely, concise and accessible evaluation of the fundamentals of network formation, structure and properties, and how these three aspects are interrelated. Chemists, technologists, materials scientists and engineers working in all areas of the polymer industry along with academic researchers in polymer science and technology will find this book an essential source of information in the course of their work.

Buch. Condizione: Neu. Neuware - There are many separate groups working in gut biology, and they feel that the gut is an excellent model for investigating general problems in differentiation, growth control, stem cell biology, and regeneration and adaptive responses. There is a pressing need to define the objectives of the next 5 to 10 years, and the meeting, Part III of the Gastroenterology Symposia Freiburg 1996 (Falk Symposium No. 94), held in Freiburg, Germany, October 25-26, brought together some of these groups with a view to identifying areas which are not being utilized and need to be exploited, such as transgenic and knockout approaches, retrovirus delivery systems, and model cell/tissue systems. The main themes of the book are gastrointestinal development and differentiation, gut stem cell biology, and the control of gut growth in normal and abnormal situations. Basic research findings are related to clinical situations, and the book will appeal not only to gut cell and molecular biologists, but also to gastroenterologists interested in the potential applications of these subject areas.

Buch. Condizione: Neu. Neuware - The interest in the problem of surface diffusion has been steadily growing over the last fifteen years. This is clearly evident from the increase in the number of papers dealing with the problem, the development of new experimental techniques, and the specialized sessions focusing on diffusion in national and international meetings. Part of the driving force behind this increasing activity is our recently acquired ability to observe and possibly control atomic scale phenomena. It is now possible to look selectively at individual atomistic processes and to determine their relative importance during growth and reactions at surfaces. The number of researchers interested in this problem also has been growing steadily which generates the need for a good reference source to farniliarize newcomers to the problem. While the recent emphasis is on the role of diffusion during growth, there is also continuing progress on the more traditional aspects of the problem describing mass transport in an ensemble of particles. Such a description is based on the statistical mechanical analysis of a collection of particles that mutually interact and develop correlations. An average over the multitude of atomistic processes that operate under these conditions is necessary to fully describe the dynamics in the system.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The societal web of life is underpinned by one concept - that of Self and Other - which emerged earlier in this century. The concept has received a new formulation within the field of the phenomenology of life and the human creative condition, finding a foothold, a point of reference that radiates novel, seminal insights. It is nothing other than the creative fulcrum of human functioning. The self-individualisation of the human being, as revealed in the present collection, is existentially and vitally intertwined with that of the Other. Tymieniecka's seminal idea of the `trans-actional' is explored in this collection of essays, which reveals a variety of significant perspectives, weaving the cycles of the human universe of existence in an essential oscillation between the Self and the Other. In this oscillation we throw out our existential tentacles, trying to gain a living space with respect to each other, all the while engaging in a mutual creative prompting and attunement. 436 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -At its meeting in April 1990 at the University of Cambridge, the Executive Committee of the International Mathematical Union (IMU) decided that the largely unorganized archives of the Union should be properly arranged and catalogued. Simultaneously, the Executive Committee expressed the wish that a history of the Union should be written [1). As Secretary of the Union, I had proposed that these issues be dis cussed at the Cambridge meeting, but without having had in mind any personal role in the practical execution of such projects. At that time, the papers of the IMU were stored in Zurich, at the Eidgenossische Technische Hochschule, and I saw no reason why they could not remain there. At about this time, Professor K. Chandrasekharan produced a handwritten article titled 'The Prehistory of the International Mathematical Union' [2), and it seemed to me that this might serve as the beginning of a more compre hensive history. I had first thought that Tuulikki MakeUiinen, who during eight years as the Office Secretary ofthe IMU had become well acquainted with the Union, would do the arranging of the archives in Zurich. She had a preliminary look at the material there, but it soon became clear that the amount of work required to bring order to it was too great to be accomplished in a few short visits from Helsinki. The total volume of material was formidable. 420 pp. Englisch.
