Buch. Condizione: Neu. Neuware - As the computer gradually automates human-oriented tasks in multiple environ ments, the interface between computers and the ever-wider population of human users assumes progressively increasing importance. In the office environment, for instance, clerical tasks such as document filing and retriev…al, and higher-level tasks such as scheduling meetings, planning trip itineraries, and producing documents for publication, are being partially or totally automated. The range of users for office oriented software includes clerks, secretaries, and businesspersons, none of whom are predominantly computer literate. The same phenomenon is echoed in the factory production line, in the securities trading floor, in government agencies, in educa tional institutions, and even in the home. The arcane command languages of yes teryear have proven too high a barrier for smooth acceptance of computerized func tions into the workplace, no matter how useful these functions may be. Computer naive users simply do not take the time to learn intimidating and complex computer interfaces. In order to place the functionality of modem computers at the disposition of diverse user populations, a number of different approaches have been tried, many meeting with a significant measure of success, to wit: special courses to train users in the simpler command languages (such as MS-DOS), designing point-and-click menu/graphics interfaces that require much less user familiarization (illustrated most clearly in the Apple Macintosh), and interacting with the user in his or her language of choice.

Buch. Condizione: Neu. Neuware - Gertrudis Van de Vijver Seminar of Logic and Epistemology University of Ghent Before being classified under the fashionable denominators of complexity and chaos, self-organization and autonomy were intensely inquired into in the cybernetic tradition. Despite all rejections that cybernetics has go…ne through in the second half of this century, today its importance is more and more recognized. Its decisive influence for connectionist theories, autopoietic and constructivist theories, for different forms of applied or experimental epistemology, is being more and more understood and generally accepted. It is mainly due to the success of connectionist models that we observe today a revival of interest for cybernetics. The 1943 article by McCulloch and Pitts is evidently a founding article. Cybernetics has however a much broader interest than the one linked to technical-mathematical details relevant to the construction of networks. For instance, the evolution from first to second order cybernetics, the ways of approaching biological and cognitive phenomena in the latter and the limits that were formulated there, are particularly meaningful to understand current developments and divergences in connectionism. A nuanced picture of cybernetic's history and its present state is therefore clearly epistemologically essential.

Buch. Condizione: Neu. Neuware - This collection of essays is dedicated to 'Joe' Karel Lambert. The contributors are all personally affected to Joe in some way or other, but they are definitely not the only ones. Whatever excuses there are - there are some -, the editors apologize to whomever they have neglected. But even so the… collection displays how influential Karel Lambert has been, personally and through his teaching and his writings. The display is in alphabetical order - with one exception: Bas van Fraassen, being about the earliest student of Karel Lambert, opens the collection with some reminiscences. Naturally, one of the focal points of this volume is Lambert's logical thinking and (or: freed of) ontological thinking. Free logic is intimately connected with description theory. Bas van Fraassen gives a survey of the development of the area, and Charles Daniels points to difficulties with definite descriptions in modal contexts and stories. Peter Woodruff addresses the relation between free logic and supervaluation semantics, presenting a novel condition which recovers desirable metatheoretic properties for free logic under that semantics. Terence Parsons shows how free logic can be utilized in interpreting sentences as purporting to denote events (true ones succeed and false ones fail) and how this helps to understand natural language.

Buch. Condizione: Neu. Neuware - In order to design and build computers that achieve and sustain high performance, it is essential that reliability issues be considered care fully. The problem has several aspects. Certainly, considering reliability implies that an engineer must be able to analyze how design decisions affect the…incidence of failure. For instance, in order design reliable inte gritted circuits, it is necessary to analyze how decisions regarding design rules affect the yield, i.e., the percentage of functional chips obtained by the manufacturing process. Of equal importance in producing reliable computers is the detection of failures in its Very Large Scale Integrated (VLSI) circuit components, caused by errors in the design specification, implementation, or manufacturing processes. Design verification involves the checking of the specification of a design for correctness prior to carrying out an implementation. Implementation verification ensures that the manual design or automatic synthesis process is correct, i.e., the mask-level description correctly implements the specification. Manufacture test involves the checking of the complex fabrication process for correctness, i.e., ensuring that there are no manufacturing defects in the integrated circuit. It should be noted that all the above verification mechanisms deal not only with verifying the functionality of the integrated circuit but also its performance.

Buch. Condizione: Neu. Neuware - Fibre-reinforced plastic (FRP) composite materials are basically of two types. The first type is short fibres reinforced in a plastic matrix, and the other type continuous (long) fibres reinforced in a plastic matrix. The exact distinction between a short and a continuous fibre is discussed in Ch…apter 1. Continuous fibre-reinforced composite materials are referred to by many labels: FRP composites, advanced composites, fibrous composites, composite materials or simply composites. These terms are now generally accepted to mean the same type of material, namely, continuous fibre reinforced in plastic. In this book, the term fibrous composites is used to define a continuous fibre reinforced in plastic. Fibrous composites are presently in use for a variety of structural applica tions, and may offer an alternative to conventional metallic materials. The behaviour of fibrous composites subjected to a loading condition is very different from that of a metallic isotropic material. Therefore, 'new' analytical and testing methods are required to analyse a structural element and sections made from layered fibrous composites. There are a number of books written on the subject of composite materials. All of these are excellent in their content and achieve the authors' objectives.

Buch. Condizione: Neu. Neuware - of progress has been made in the development of In the last twenty years a great amount new magnetic materials. Permanent magnets have progressed from the AlNiCo's (with (BH)m-8 MGOe) to the strong rare-earth magnets of SmCo 'BH)m-20 MGOe), Sm2(Co,Fe,Cu,Zrh7 s 'BH)m-30 MGOe) and the recently disc…overed Nd-Fe-B super-magnets with (BH)m-50 MGOe. For years the magnetic storage industry has employed Fe0 and CrO for storage media and 2 3 z permalloys and ferrites for recording heads. The recent development of thin film heads, the demand of higher density of information storage and the emergence of completely new technologies, like magneto-optics, call for entirely new types of magnetic materials. Another area in which new techniques of materials preparation have made a dramatic impact is the epitaxial growth of magnetic films. Recent work has shown that this process can be controlled on the scale of atomic monolayers permitting the growth of totally artificial structures, such as artificial superlattices with a resolution on this scale. Epitaxial growth has also permitted the stabilization of metastable phases in thin film form. These new phases often possess striking properties, such as strong perpendicular anisotropies, which may prove useful for technological applications such as recording. Research on magnetic multilayers and superlattices is increasing at an accelerating pace. Complex couplings between different magnetic layers lead to new properties not seen in bulk materials.

Buch. Condizione: Neu. Neuware - Cardiac disease is the major cause of death in dialysis patients, accounting for over one third of deaths. This book focuses on myocardial function and dysfunction in chronic uremia. It is aimed at practicing and training nephrologists, cardiologists, and internists, and at research workers in th…e field. We have tried to produce an up-to-date, in-depth review of the subject by inviting experts in clinical epidemiology, pathophysiology, and thera peutics to write the 18 chapters. The book is divided into three sections. The first section comprises five chapters that provide an overview of the burden of illness associated with cardiac disease in end-stage renal disease and a review of clinical epidemi ological aspects of various cardiac diseases that occur in renal patients. The second section discusses abnormalities of left ventricular contractility and mass, and the factors that predispose to both systolic and diastolic disorders. The importance of hypertension, anemia, hyperparathyroidism, hyper lipidemia, and diabetes mellitus in predisposing to these abnormalities is reviewed splendidly by researchers active in these areas. The final section concentrates on therapeutics. Data and opinion on management of congestive heart failure, cardiomyopathy, coronary artery disease, hypertension, and arrhythmias are provided. In editing this book, we have reviewed an extensive literature, but un fortunately we have become more aware that substantial gaps in our knowl edge exist. Insufficient high-quality clinical research has been undertaken xiii xiv Preface regarding the various cardiac diseases that occur in end-stage renal disease.

Buch. Condizione: Neu. Neuware - This book contains a selection of papers presented at the 'European Robotics and Intelligent Systems Conference' (EURISCON '91) held in Corfu. Greece (June 23-28. 1991). It is devoted to the analysis. design and applications of technological systems with built-in intelligence achieved through app…ropriate blending of mathematical, symbolic. sensing. computer processing. and feedback control concepts. methods and software / hardware tools. System intelligence includes human-like capabilities such as learning. observation. perception. interpretation. reasoning. planning. decision making. and action. Integrated intelligent decision and control systems obey Saridis' prinCiple of Increasing Precision with Decreasing Intelligence (IPDI). and have a hierarchical structure with three basic levels. namely Organization. Coordination. and Execution Levels. As we proceed from the organization to the execution level. the precision about the jobs to be completed increases and accordingly the intelligence reqUired for these jobs decreases. As an example. it is mentioned here that in an intelligent robotic system the organization tasks can be realized using a neural net. the coordination tasks by a Petri net. and the execution tasks by local sensors and actuators. The field of intelligent systems is a new interdisciplinary field with continuously increasing interest and expansion. It is actually the outcome of the synergetic interaction and cooperation of classical fields such as system theory. control theory. artificial intelligence. operational research. information theory. electronics. communications. and others.

Buch. Condizione: Neu. Neuware - This book consists of papers prepared for and presented at a NATO sponsored Advanced Study Institute which was held in Montechoro, Portugal during the period 16-27 April, 1990. This Institute was attended by approximately ninety delegates from fifteen countries and followed from a related Institu…te held in Vimeiro, Portugal in 1987 (see the book entitled 'Instrumentation for Combustion and Flow in Engines', edited by D. F. G. Dur~o, J. H. Whitelaw and P. O. Witzel. The purposes of the first Institute related closely to instrumentation for use in gas-turbine combustors and the cylinders of internal-combustion engines. These topics were also addressed in the second Institute, though in a manner which was wider ranging and chosen to demonstrate and explain the development and application of measurement methods to combusting flows in general. The papers contained in this boo~ were selected to provide the reader with a comprehensive and up-to-date view of the variety of experimental techniques available to measure in combusting flows. Included are discussions of their range and applicability, potential accuracy and ease of use. Thus, the first paper provides a brief overview and the second an indication of those aspects of combustion which should influence the choice of flow property to be measured and the technique to be used.

Buch. Condizione: Neu. Neuware - Research and publications on the potato crop have burgeoned since the first edition of this book was published in 1978. However, the warm reception of the first edition suggested that it had a useful part to play in promoting the scientific basis for understanding and improving the yield and qual…ity of the crop. Since the first edition was out of print and a second reprint would not have taken into account the contributions made by research over the intervening years, it became obvious that a complete revision was necessary. There was, in particular, a need to take account of the rapid extension of interest in the crop into climates and farming systems with which it has not been traditionally associa,ted. Those involved with the crop will be sadly aware that a number of contributors to the first edition are no longer with us. Their contribution to our knowledge of the crop will however be a permanent legacy of their achievement. I would like to thank all those who have contributed to the book for their willingness to cooperate in the difficult task of bringing their particular subject up to date. This is even more noteworthy for the pressure of time appears to be almost an order of magnitude higher than it was when the first edition was tackled.

The first part o…f the book develops certain hyperspace theory concerning the Hausdorff metric and the Vietoris topology, as a foundation for what follows on self-similarity and fractality. A major feature is that nonstandard analysis is used to obtain new proofs of some known results much more slickly than before. The theory of J.E. Hutchinson's invariant sets (sets composed of smaller images of themselves) is developed, with a study of when such a set is tiled by its images and a classification of many invariant sets as either regular or residual. The last and most original part of the book introduces the notion of a 'view' as part of a framework for studying the structure of sets within a given space. This leads to new, elegant concepts (defined purely topologically) of self-similarity and fractality: in particular, the author shows that many invariant sets are 'visually fractal', i.e. have infinite detail in a certain sense. These ideas have considerable scope for further development, and a list of problems and lines of research is included. 180 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -AIDS and drug addiction is a topic of great and growing concern. AIDS first appeared among intravenous drug users in Europe in 1984, three years after the first cases were seen among homosexuals. This epidemic has spread more rapid…ly among intravenous drug users than in any other risk group. The high rates of HIV-1 seroprevalence among drug users in France, Italy, and Spain account for 85% of the total number of AIDS in intravenous drug users in Europe. It is anticipated that HIV-infected drug users will soon place a heavy burden on both drug treatment facilities and specialized health care units. The HIV-1 epidemic will also cross the former iron curtain. This contribution covers the wide and complex scene of drug problems and addiction as a whole. It gives researchers an opportunity to obtain background information on the spread of HIV and AIDS among intravenous drug users as well as on the clinical and psychological effects of HIV-1 infection and AIDS in Europe. The topics reviewed include surveys of intravenous drug use, HIV prevalence, detoxification, risk reduction, changing health behaviors, evaluating AIDS interventions and the impact of methadone maintenance treatment. This monograph will be of value to all clinicians, researchers, and policy makers who are concerned with the connection between intravenous drug use and AIDS. Die Ausbreitung von HIV und AIDS unter Drogensüchtigen wird auch in Europa zu einem zunehmend größeren Problem. Dieses Buch gibt einen breiten Überblick über den gegenwärtigen Stand der therapeutischen Strategien. 444 pp. Englisch.

The conference was held from August 11 to August 15, 1990 and was sponsored by the International Association f…or Cryptologic Research, in cooperation with the IEEE Computer Society Technical Committee on Security and Privacy and the Department of Computer Science of the University of California at Santa Barbara. 227 participants from twenty countries around the world. Crypto '90 attracted Roughly 35% of attendees were from academia, 45% from industry and 20% from government. The program was intended to provide a balance between the purely theoretical and the purely practical aspects of cryptography to meet the needs and diversified interests of these various groups. The overall organization of the conference was superbly handled by the general chairperson Sherry McMahan. All of the outstanding features of Crypto, which we have come to expect over the years, were again present and, in addition to all of this, she did a magnificent job in the preparation of the book of abstracts. This is a crucial part of the program and we owe her a great deal of thanks. 664 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the papers from the first British Neural Network Society meeting held at Queen Elizabeth Hall, King's College, London on 18--20 April 1990. The meeting was sponsored by the London Mathemati cal Society. The pap…ers include introductory tutorial lectures, invited, and contributed papers. The invited contributions were given by experts from the United States, Finland, Denmark, Germany and the United Kingdom. The majority of the contributed papers came from workers in the United Kingdom. The first day was devoted to tutorials. Professor Stephen Grossberg was a guest speaker on the first day giving a thorough introduction to his Adaptive Resonance Theory of neural networks. Subsequent tutorials on the first day covered dynamical systems and neural networks, realistic neural modelling, pattern recognition using neural networks, and a review of hardware for neural network simulations. The contributed papers, given on the second day, demonstrated the breadth of interests of workers in the field. They covered topics in pattern recognition, multi-layer feedforward neural networks, network dynamics, memory and learning. The ordering of the papers in this volume is as they were given at the meeting. On the final day talks were given by Professor Kohonen (on self organising maps), Professor Kurten (on the dynamics of random and structured nets) and Professor Cotterill (on modelling the visual cortex). Dr A. Mayes presented a paper on various models for amnesia. The editors have taken the opportunity to include a paper of their own which was not presented at the meeting. 320 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The research described in this monograph concerns the formalspecification and compositional verification of real-timesystems. A real-time programminglanguage is considered inwhich concurrent processes communicate by synchronousmess…age passing along unidirectional channels. To specifiyfunctional and timing properties of programs, two formalismsare investigated: one using a real-time version of temporallogic, called Metric Temporal Logic, and another which isbasedon extended Hoare triples. Metric Temporal Logicprovides a concise notationto express timing properties andto axiomatize the programming language, whereas Hoare-styleformulae are especially convenient for the verification ofsequential constructs. For both approaches a compositionalproof system has been formulated to verify that a programsatisfies a specification. To deduce timing properties ofprograms, first maximal parallelism is assumed, modeling thesituation in which each process has itsown processor. Next,this model is generalized to multiprogramming where severalprocesses may share a processor and scheduling is based onpriorities. The proof systems are shown to be sound andrelatively complete with respect to a denotational semanticsof the programming language. The theory is illustrated by anexample of a watchdog timer. 252 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this monograph the local disturbance decoupling problemwith stability istreated for nonlinear systems. Thisproblem consists in finding a (dynamic) state feedback for agiven control system with two kinds of inputs, viz.controlled… inputs and (uncontrolled) disturbances such thatafter application of this feedback the outputs are notinfluenced by the disturbances and the resulting internaldynamics are locally exponentially stable. In case onlystatic state feedback is allowed two essentially differentsolutions are obtained, viz. a fundamental one and a moreproblem-oriented one. Both methods generalize well-knownsolutions for linear systems. In the last chapter a solutionis found in case dynamic state feedback is allowed. Here atypical nonlinear phenomenon is pointed out, namely thatthere exist nonlinear systems for which the disturbancedecoupling problem (with stability) can be solved byapplying dynamic feedback, but not by using static feedback.The bookis intended for researchers in mathematicalnonlinear systems theory. Geometric techniques play a keyrole in the book. Therefore, in Chapter 6 algebraictechniques are recalled and used. 148 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of this book is to bring together the most recent knowledge concerning the genetic improvement of ornamental plant species. Active researchers of many aspects of the genetics and breeding of these species have written c…hapters organized into three sections: Cytogenetics, Quantitative Genetics and Molecular Genetics. These titles identify the basic tools used in a variety of breeding situations. Some are traditional and well established; others offer new and exciting challenges for the future. vii Introduction The purpose of this book is to bring together recent knowledge concerning the genetic improvement of ornamental plant species. In the 20th century flower breeding has become widespread leading to many improvements in phenotypic and production characteristics of ornamental species. These methods depends on the creation and subsequent selection of genetic vari ability. Lack of variability in gene pools has been a chief limitation to the success of flower breeding. Recent progress in molecular biology makes it possible to add genetically well-defined characteristics to gene pools, thus increasing the potential for genetic improvement. These methods also enable the specific silencing of genetic information to accomplish an intentional loss of function. This book compiles current knowledge of the cytogenetics, quantitative genetics, and molecular genetics of ornamental plant species. The three sections identify the basic tools used in a variety of breeding situations. 444 pp. Englisch.
