Buch. Condizione: Neu. Neuware - New interest in light microscopy of the last few years has not been backed up by adequate general literature. This book intends to fill the gap between specialized texts on detailed topics and general introductory booklets, mostly dealing with the use of the conventional light microscope only. In… this short textbook both new developments in microscopy and basic facts of image formation will be treated, including often neglected topics such as axial resolving power, lens construction, photomicrography and correct use of phase-en interference contrast systems. Theoretical background will be dealt with as far as necessary for a well-considered application of these techniques enabling a deliberate choice for the approach of a certain problem. Over 150 illustrations (photomicrographs and diagrams) complete the information on microscopy of the nineties in the biomedical field, intended for scientists, doctors, technicians and research students. Many drawings have been contributed by the illustrator R. Kreuger; the photographic work has been executed by J. Peeterse. Secretarial assistance in preparing the manuscript was given by Ms T. M. S. Pierik. Dr M. J. Pearson has corrected the English of the final text.

Buch. Condizione: Neu. Neuware - financial markets suggests that factors such as differences in capital requirements, limi tations on size or on the range of financial activities in which firms can engage, govern ment guarantee arrangements for deposits or payments, and reporting or disclosure requirements can have important eff…ects on the efficiency of industrial and commercial firms and thus on the international competitive positions of major sectors of the U.S. economy. Regulatory and tax policies must therefore take into account effects on inter national competitive positions in addition to domestic concerns. The articles in this issue analyze differences in market organization and regulation across countries and examine how efficiency in producing financial services is influenced by these differences. These articles were presented and discussed at a conference sponsored by the Amer ican Enterprise Institute in Washington, D.C., on May 31 and June 1, 1990. This confer ence on International Competitiveness in Financial Services brought to the attention of Washington policy officials these analyses by leading scholars in finance. Publication of these studies and critiques in the Journal of Financial Services Research is intended to stimulate further interest in research on these important issues.

Buch. Condizione: Neu. Neuware - We would like to take this opportunity to thank all of those individ uals who helped us assemble this text, including the people of Lockheed Sanders and Nestor, Inc., whose encouragement and support were greatly appreciated. In addition, we would like to thank the members of the Lab oratory for E…ngineering Man-Machine Systems (LEMS) and the Center for Neural Science at Brown University for their frequent and helpful discussions on a number of topics discussed in this text. Although we both attended Brown from 1983 to 1985, and had offices in the same building, it is surprising that we did not meet until 1988. We also wish to thank Kluwer Academic Publishers for their profes sionalism and patience, and the reviewers for their constructive criticism. Thanks to John McCarthy for performing the final proof, and to John Adcock, Chip Bachmann, Deborah Farrow, Nathan Intrator, Michael Perrone, Ed Real, Lance Riek and Paul Zemany for their comments and assistance. We would also like to thank Khrisna Nathan, our most unbi ased and critical reviewer, for his suggestions for improving the content and accuracy of this text. A special thanks goes to Steve Hoffman, who was instrumental in helping us perform the experiments described in Chapter 9.

Buch. Condizione: Neu. Neuware - For several years, I have been responsible for organizing and teaching in the fall a short course on 'Fundamentals of Adhesion: Theory, Practice, and Applications' at the State University of New York at New Paltz. Every spring I would try to assemble the most pertinent subjects and line up severa…l capable lecturers for the course. However, there has always been one thing missing-an authoritative book that covers most aspects of adhesion and adhesive bonding. Such a book would be used by the participants as a main reference throughout the course and kept as a sourcebook after the course had been completed. On the other hand, this book could not be one of those 'All you want to know about' volumes, simply because adhesion is an interdisciplinary and ever-growing field. For the same reason, it would be very difficult for a single individual, especially me, to undertake the task of writing such a book. Thus, I relied on the principle that one leaves the truly monumental jobs to experts, and I finally succeeded in asking several leading scientists in the field of adhesion to write separate chapters for this collection. Some chapters emphasize theoretical concepts and others experimental techniques. In the humble beginning, we planned to include only twelve chapters. However, we soon realized that such a plan would leave too much ground uncovered, and we resolved to increase the coverage. After the book had evolved into thirty chapters, we started to feel that perhaps our mission had been accomplished.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Knowledge-based systems have been successfully developed in practice for a number of years. However, they are often 'only' stand-alone systems; integrating them into existing information environments, e.g. making available real pro…duction data to an expert system, often either fails or is only solved in a dissatisfying way. Possible reasons for this might be on one hand the lack of know-how about the different features of various experimental AI techniques, and on the other the lack of more classical information and database system technology. The special interest groups 'Knowledge Representation' and 'Methods for the Development of Information Sys- tems and their Application' of the German Informatics Society (GI) organized a joint workshop in Ulm in March 1990 to discuss the integration of Artificial Intelligence and database technology. This volume contains the proceedings of the workshop. 308 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This thesis is a theoretical study of the optimal dynamic policies of a, to some extent, slowly adjusting firm that faces an exogeneously given technological progress and an exogeneously given business cycle. It belongs to the area… of mathematical economics. It is intended to appeal to mathematical economists in the first place, economists in the second place and mathematicians in the third place. It entails an attempt to stretch the limits of the application of deterministic dynamic optimisation to economics, in particular to firm behaviour. A well-known Dutch economist (and trained mathematician) recently stated in 1 a local university newspaper that mathematical economists give economics a bad reputation, since they formulate their problems from a mathematical point of view and they are only interested in technical, mathematical problems. At the same time, however, 'profound as economists may be, when it comes to extending or modifying the existing theory to make it applicable to a certain economic problem, an understanding of optimal control theory (which is the mathematical theory used in this thesis, ovh) based solely on heuristic arguments will often turn out to be inadequate' (SydS 248 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is based on the Stockholm conference on Culture, Language and Artificial Intelligence, which was organised by the Swedish Arbetslivascentrum in 1988. This conference brought together over three hundred and sixty people…interested in the cultural impact of technology, and particularly of AI. The 20 challenging papers contained in this volume were presented, or prepared, at the conference. This book aims to demonstrate the breadth and complexity of the concept of 'dialogue', particularly in relation to new technolgy and what follows in its wake: the effects it has on the development and preservation of occupational knowledge and skills, and its effects on society, culture and language. The philosophical and aesthetic nature of the contributions is due to the influence of the Dialogue Seminar, which was held continuously at the Royal Dramatic Theatre in Stockholm during the conference, and in which several of the contributors to this book participated. 216 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -On the basis of a semantic analysis of dimension terms, this book develops a theory about knowledge of spatial objects, which is significant for cognitive linguistics and artificial intelligence. This new approach to knowledge stru…cture evolves in a three-step process: - adoption of the linguistic theory with its elements, principles and representational levels, - implementation of the latter in a Prolog prototype, and - integration of the prototype into a large natural language understanding system. The study documents interdisciplinary research at work: the model of spatial knowledge is the fruit of the cooperative efforts of linguists, computational linguists, and knowledge engineers, undertaken in that logical and chronological order. The book offers a two-level approach to semantic interpretation and proves that it works by means of a precise computer implementation, which in turn is applied to support a task-independent knowledge representation system. Each of these stages is described in detail, and the links are made explicit, thus retracing the evolution from theory to practice. 152 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Modern electronics is the most visible result of research in solid state physics. Transistors and integrated circuits are used everywhere in ever increasing numbers. The microprocessor controlled coffee-pot exists. Most experimenta…l physicists, and, indeed, experimental scientists in most disciplines, study their subject with the aid of apparatus containing significant amounts of electronics and much of that electronics is digital. In order to design experiments and apparatus or simply to understand how a piece of equipment works, an under standing of electronics has become increasingly important. In recognition that electronics has pervaded so many areas, courses in digital electronics are now a recommended part of physics and many other science degree courses. At the introductory level, digital electronics is, primarily, a practical subject with relatively few basic concepts and any complex ity arises from the coupling together of many simple circuits and the extensive use of feedback. Designing an electronic circuit and then getting it to work correctly provides an experience, and a sense of achievement, which is significantly different from most undergradu ate work as it more closely resembles project work than standard laboratory practicals. 232 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Lipids can usually be extracted easily from tissues by making use of their hydrophobic characteristics. However, such extractions yield a complex mixture of different lipid classes which have to be purified further for quantitative… analysis. Moreover, the crude lipid extract will be contami nated by other hydrophobic molecules, e.g. by intrinsic membrane proteins. Of the various types of separation processes, thin layer and column chromatography are most useful for intact lipids. High performance liquid chromatography (HPLC) is also rapidly becoming more popular, especially for the fractionation of molecular species of a given lipid class. The most powerful tool for quantitation of the majority of lipids is gas liquid chromatography (GLC). The method is very sensitive and, if adapted with capillary columns, can provide information with regard to such subtle features as the position or configuration of substitutions along acyl chains. By coupling GLC or HPLC to a radioactivity detector, then the techniques are also very useful for metabolic measurements. Although research laboratories use generally sophisticated analytical methods such as GLC to analyse and quantify lipid samples, chemical derivatie:ations are often used in hospitals. For these methods, the lipid samples are derivatized to yield a product which can be measured simply and accurately-usually by colour. Thus, total triacylglycerol, cholesterol or phospholipid-phosphorus can be quantitated conveniently without bothering with the extra information of molecular species, etc. which might be determined by more thorough analyses.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In many fields of application of mathematics, progress is crucially dependent on the good flow of information between (i) theoretical mathematicians looking for applications, (ii) mathematicians working in applications in need of t…heory, and (iii) scientists and engineers applying mathematical models and methods. The intention of this book is to stimulate this flow of information. In the first three chapters (accessible to third year students of mathematics and physics and to mathematically interested engineers) applications of Abel integral equations are surveyed broadly including determination of potentials, stereology, seismic travel times, spectroscopy, optical fibres. In subsequent chapters (requiring some background in functional analysis) mapping properties of Abel integral operators and their relation to other integral transforms in various function spaces are investi- gated, questions of existence and uniqueness of solutions of linear and nonlinear Abel integral equations are treated, and for equations of the first kind problems of ill-posedness are discussed. Finally, some numerical methods are described. In the theoretical parts, emphasis is put on the aspects relevant to applications. 232 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book deals with the theory of macroscopic systems. Traditionally this theory has been fragmented over a number of disciplines like thermodynamics, physical transport phenomena, sometimes referred to as non-equilibrium or irrev…ersible thermodynamics, fluid mechanics, chemical reaction engineering and heat and power engineering. This fragmentation, the different approaches followed in presenting theory, e.g. the inductive approach as opposed to the postulational approach in textbooks on thermodynamics, many alternative representations of equations and differences in notation make it cumbersome to discern a single coherent theory of macroscopic systems. The idea of this book is to present the theory of macroscopic systems as a unified theory with equations strictly developed from a single set of principles and concepts. The book is an attempt to bridge gaps between the various disciplines. It can serve as a textbook, refresher or reference book to students of an advanced level in various disciplines, to scientists and to practising engineers working in design and development. It provides rigorous equations and their possible simplifications for use in computer models for scale-up or optimisation. Topics like exergy analysis and multi component diffusion are included. The principles and concepts in the theory of macroscopic systems com prise in addition to the mole and mass balances over a system, the balance equations for the fundamental extensive properties momentum, energy and entropy as well as the phenomenological laws on asymptotic phase behaviour and molecular transport. 268 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first Interfaces Conference was held at Swansea in April 1988 and represented the then state of the art of the science of implant surgery. The motivation for the initial venture was a supposed need for a closer interaction and dialogu…e between the clinician and scientist working in this area. As expressed in the Preface to the first Conference, we felt that the interface was represented graphically, scientifically and psychologically by the drawings of Edgar Rubins (1915), again widely used in the literature to the present Proceedings. The first Conference, we believe, achieved the aims of the organisers in bringing together scientists and clinicians towards an exchange of ideas by logically pursuing the sequence of events in clinical implant surgery. The present Conference, in collaboration with our Italian colleagues, has also attempted to achieve the same aims by examining the behaviour of implants constructed of a variety of materials in both hard and soft tissue. Many contributions in the conference employed the technique of finite element analysis, both for design and optimisation purposes, particularly in relation to bone remodelling. Indeed, this particular aspect of the Conference led to much debate and will require a major examination of the many levels of physical, chemical and biomechanical interactive behaviour of the implant and its environment. All this natural behaviour was presented and discussed, but difficulties and failures remain with such procedures and we feel it is only by continuing such meetings that we progress in this difficult area of clinical science. 516 pp. Englisch.

Therefore, whether a type of behavior of an organism is adequate as a certain configuration of movements, will depend on the environment in which we de sc…ribe it. ' (Humberto Maturana, Francisco Varela: El arbol del conocimiento, 1984) 'A thorough analysis of behavior must result in a scheme, that shows all regularities that are to be found between the sensorical input and the motorical output of an animal. This scheme is an abstract representation of the brain. ' (Valentin Braitenberg: Gehirngespinste, 1973) During the 70ies, when Biomathematics (beyond Biomedical Statistics and Com puting) became more popular at universities and research institutes, the problems dealt with came mainly from the general fields of 'Population Biology' and 'Complex Systems Analysis' such as epidemics, ecosystems analysis, morphogenesis, genetics, immunology and neurology (see the first series of Springer Lecture Notes in Biomathematics). Since then, the picture has not considerably changed, and it seems that 'a thorough analysis of behavior' of single organisms and, moreover, of their mutual interactions, is far from being understood. On the contrary, mathematical modellers and analysts have been well advised to restrict their investigations to specific aspects of 'biological behavior', one of which is 'biological motion'. Until now, only a few Conference Proceedings or Lecture Notes have paid attention to this important aspect, some of the earlier examples being Vol. 24: 'The measurement of biological shape and shape changes' (1978) or Vol. 620 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is the proceedings of the Second Advanced School on Artificial Intelligence (EAIA '90) held in Guarda, Portugal, October 8-12, 1990. The focus of the contributions is natural language processing. Two types of subject ar…e covered: - Linguistically motivated theories, presented at an introductory level, such as X-bar theory and head- driven phrase structure grammar, - Recent trends in formalisms which will be familiar to readers with a background in AI, such as Montague semantics and situation semantics. The topics were chosen to provide a balanced overview of the most important ideas in natural language processing today. Some of the results presented were worked out very recently, are the subject of ongoing research, and have not previously appeared in book form. This book may serve as a textbook: in fact its contents were intended as lecture notes. 268 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In August 1988. the Sixth International Coral Reef Symposium was held in Townsville resulting in an influx of most of the world's coral reef sCientists to the city. We seized this opportunity at the Australian Institute of Marine S…cience to run a small workshop immediately before the symposium on the outbreaks of the crown-of-thorns starfish. Aeanthaster planei. We invited that small band of mathematicians who had been modelling the phenomenon, (and who may not have normally attended an international meeting so thoroughly dedicated to natural science) to meet with those SCientists who had been been actively working on the phenomenon in the field. John Casti notes in his delightful new book Alternate Realities (Wiley, 1989): 'If the natural role of the experimenter is to generate new observables by which we know the processes of Nature, and the natural role of the mathematician is to generate new formal structures by which we can represent these processes. then the system SCientist finds his niche by serving as a broker between the two. ' I think our book shows the fruits of that brokerage through the wide range of models explored within its pages. the high level of collaboration and interaction across disciplines evident in the individual papers, and in the emerging synthesis that reflects a far deeper understanding of this complex phenomenon than was possible even a few years ago. 352 pp. Englisch.
