Buch. Condizione: Neu. Neuware - Data archiving has, for many years, been the most disregarded aspect of all data systems. The increase in numbers of telescopes, both groundbased and space-borne, and the increase in efficiency of detectors have generated overwhelming amounts of data. Much of these data were and are not used on short timescales and (should) have been archived, where they can be used later and/or by others. Archiving is essential. Objects can change in the course of time. New technological or scientific developments might require observing objects again. The cost-benefit ratio will become more and more important when considering the allocation of telescope time. The retrieval of `old' data can then be crucial. At present there are a number of data collections and data retrieval systems. This book includes a series of clear and up-to-date descriptions of many important available data systems. For professional astronomers, librarians and computer engineers.

Buch. Condizione: Neu. Neuware - This book is an extension of one author's doctoral thesis on the false path problem. The work was begun with the idea of systematizing the various solutions to the false path problem that had been proposed in the literature, with a view to determining the computational expense of each versus the gain in accuracy. However, it became clear that some of the proposed approaches in the literature were wrong in that they under estimated the critical delay of some circuits under reasonable conditions. Further, some other approaches were vague and so of questionable accu racy. The focus of the research therefore shifted to establishing a theory (the viability theory) and algorithms which could be guaranteed correct, and then using this theory to justify (or not) existing approaches. Our quest was successful enough to justify presenting the full details in a book. After it was discovered that some existing approaches were wrong, it became apparent that the root of the difficulties lay in the attempts to balance computational efficiency and accuracy by separating the tempo ral and logical (or functional) behaviour of combinational circuits. This separation is the fruit of several unstated assumptions; first, that one can ignore the logical relationships of wires in a network when considering timing behaviour, and, second, that one can ignore timing considerations when attempting to discover the values of wires in a circuit.

Buch. Condizione: Neu. Neuware - Electronic Money Flows describes the far-reaching present changes under way in payments and capital markets. Electronic payment forms are in the process of molding a new financial regime-largely shared and inter dependent-throughout the world. Our earlier Electronic Funds Transfers and Payments (Kluwer, 1987) looked at the new money technology in its initial phases of development and in broad focus. Then, as now, the contributors came from many different disciplines. The synthesis of their diverse views laid out the background for the electronic payments revolution to come, and the great benefits but also risks for segmented sectors of society. The old questions have not gone away; new ones have been added to the agenda. For example, what is the nature of money today amidst an array of computer-based options What money and turnover concepts are appropriate to the electronic age What are the effects of high-speed money flows on markets, volatility, money control, even the business cycle Is the financial system more prone to instability but also to faster correction, given the swift movement of money and payments At the same time, is privacy imperilled by the ubiquitous computer-linked webs that move both information and money This second book is thus companion to Electronic Funds Transfers and Payments and expands upon it. Contributors discuss the expectations that have and have not come to fruition, together withthe new issuesofthe past four years.

Buch. Condizione: Neu. Neuware - It is a great honor to provide a few words of introduction for Dr. Georges Gielen's and Prof. Willy Sansen's book 'Symbolic analysis for automated design of analog integrated circuits'. The symbolic analysis method presented in this book represents a significant step forward in the area of analog circuit design. As demonstrated in this book, symbolic analysis opens up new possibilities for the development of computer-aided design (CAD) tools that can analyze an analog circuit topology and automatically size the components for a given set of specifications. Symbolic analysis even has the potential to improve the training of young analog circuit designers and to guide more experienced designers through second-order phenomena such as distortion. This book can also serve as an excellent reference for researchers in the analog circuit design area and creators of CAD tools, as it provides a comprehensive overview and comparison of various approaches for analog circuit design automation and an extensive bibliography. The world is essentially analog in nature, hence most electronic systems involve both analog and digital circuitry. As the number of transistors that can be integrated on a single integrated circuit (IC) substrate steadily increases over time, an ever increasing number of systems will be implemented with one, or a few, very complex ICs because of their lower production costs.

Buch. Condizione: Neu. Neuware - Solders have given the designer of modern consumer, commercial, and military electronic systems a remarkable flexibility to interconnect electronic components. The properties of solder have facilitated broad assembly choices that have fueled creative applications to advance technology. Solder is the electrical and me chanical 'glue' of electronic assemblies. This pervasive dependency on solder has stimulated new interest in applica tions as well as a more concerted effort to better understand materials properties. We need not look far to see solder being used to interconnect ever finer geo metries. Assembly of micropassive discrete devices that are hardly visible to the unaided eye, of silicon chips directly to ceramic and plastic substrates, and of very fine peripheral leaded packages constitute a few of solder's uses. There has been a marked increase in university research related to solder. New electronic packaging centers stimulate applications, and materials engineering and science departments have demonstrated a new vigor to improve both the materials and our understanding of them. Industrial research and development continues to stimulate new application, and refreshing new packaging ideas are emerging. New handbooks have been published to help both the neophyte and seasoned packaging engineer.

'Martin Bailyn's Survey is a marvelous resource for any teacher of thermal physics.The writing is clear; the references are extensive. If the textbook from which you are teaching leaves you dissatisfied with its treatment of a specific topic, Bailyn's compendium is a good place to look for a different or a deeper presentation.' American Journal of Physics This work presents the application and theory of thermodynamics, including its formation according to statistical mechanics and its extension into Special Relativity. A unique feature of this book is the addition of the history of thermodynamics, designed to illustrate and emphasize the development of present day concepts. This book provides valuable insights into how these concepts evolved by discussing the pioneering work of Galileo, Clasuius, Kelvin, and others. The inclusion of both a complete survey of the subject, and an historical background (not found in other books) make this a valuable reference for individuals and graduate students.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is about the new materials now being created in order to fulfil specific scientific needs. This is one of the key fields within the new discipline of Molecular Engineering. The principles governing the structure of solids and their surfaces are described with examples drawn from ionic crystals, molecular crystals, valence crystals and alloys. Although many of the topics are related to Solid State Physics they are here introduced from a chemical rather than a physical point of view in order to open up the subject to a wider audience. The main text tries to remain simple by exploiting fully a modest number of theoretical ideas. An important aim of the text is to bridge the gap between the average chemistry degree course and the rapidly expanding research literature of the subject. Der Autor erklärt die Struktur der festen Materie mit Bezug auf ihre beobachtbaren Eigenschaften. Die Rolle der Oberfläche wird ebenso dargestellt wie die möglichen katalytischen Eigenschaften von Clustern. Kooperative Effekte in Festkörpern und Legierungen werden mit einfachen Modellen beschrieben. Die physikalischen Grundlagen erklärt der Autor in der Sprache und mit den Modellen der Chemiker. Das Buch wendet sich an Chemiestudenten im 2. Studienabschnitt, die sich mit den Grundlagen des 'Molecular Engineering' vertraut machen wollen. 168 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present book collects a broad overview of chemical and physical char acteristics of silicon oxynitrides. Special emphasis is put on the way in which these properties influence the electrical characteristics and behaviour of this important material. The results presented here were obtained in an ex tended European research cooperation in the framework of ESPRIT Project 369 'Physical-chemical characterization of silicon oxynitrides in relation to their electrical properties', which ran from 1984 to 1988. In this project two industrial laboratories (Philips Research Laborato ries in Eindhoven, the Netherlands, and Matra Harris Semiconductors from Nantes, France) cooperated with various academic and government research laboratories (Harwell Laboratory in Great Britain, the Interuniversity Micro electronics Center (IMEC) in Leuven, Belgium, and the Faculty of Physics at the University of Utrecht in the Netherlands). The latter partner acted as prime contractor for the project. General interest in silicon oxynitrides for applications in integrated circuit technology stems from the fact that proper choice of deposition conditions enables one to produce materials with properties which can be either oxide like or nitride-like. Of, course, in I.C. technology one would like to combine the good properties ofthe two materials, i.e. superior electrical properties of silicon oxide and good diffusion barrier behaviour of silicon nitride, to men tion only a few, without paying for such an operation by obtaining all the less desirable properties in such a mixed material. 172 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In November 1989 we organised a workshop on software re-use, inviting members of the leading research teams across Europe. In retrospect, we realise that we missed a few research teams out, but nevertheless we did have a very fruitful workshop. This book is the outcome of that meeting. Prior to the workshop, teams submitted short position papers, and at the workshop made very short presentations of these. Most of the time was spent in four parallel sessions, and the reports of these sessions are given in Chapter 2. After the workshop we invited the attendees to revise and resubmit their papers in the light of the workshop, and it is these updated papers that appear in Chapter 4 onwards. The papers are in alphabetical order of first author. To complete this text we have added an introduction to software re-use as a first chapter-this was prepared by Liesbeth Dusink. We have added a comprehensive bibliography as Chapter 3, merging the bibliographies accumulated at Delft and at Brunei. To be able to organise the workshop we were sponsored by SERC, the Software Engineering Research Centre in Utrecht, Netherlands.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The second 'African Mining' conference is planned for June 1991, and follows the first, very successful, event held in May 1987. That full four-year period was characterized by substantial changes in the political and economic climate of many countries in both hemispheres. Copper prices were relatively firm, and the advance and steady demand for nickel and ferrochromium stabilized important sectors of the mineral industry, certainly in Zimbabwe. The promise for gold remained unfulfilled, but the smaller, relatively flexible, mines survived and only the large, deep and low-value mines seem seriously at risk. None of this has affected the hungry, and intensive exploitations from surface to the water-table have revealed many targets of promise to those willing to take the risks. The pattern in Southern Africa was extraordinarily stable among the turmoil, with independence for Namibia, adjustments in South Africa and a gradual shift to market economies in the region. The pace of exploration has increased to recover some part of the progress that was lost in the Independence struggle, and atthe end of the first decade in Zimbabwe, for example, oil is being sought in the Zambesi Rift, following the investigation of the Luangwa in Zambia, and there are exciting exploration projects for methane released from coal, deep in its basins. 376 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Intended for use in college courses for prospective or in-service secondary school teachers of geometry. Designed to give teachers broad preparation in the content of elementary geometry as well as closely related topics of a slightly more advanced nature. The presentation and the modular format are designed to incorporate a flexible methodology for the teaching of geometry, one that can be adapted to different classroom settings. The basic strategy is to develop the few fundamental concepts of elementary geometry, first in intuitive form, and then more rigorously. The rest of the material is then built up out of these concepts through a combination of exposition and 'guided discovery' in the problem sections. A separate volume including the solutions to the exercises is also available. 352 pp. Englisch.

Practitioners and scientists in ecology, environmental sciences, limnology, hydrology and geosciences but also in agricultural and life sciences will profit from this textbook. It is the first book on ecometric modeling. Ecometry is an approach to establish so-called load diagrams (effect-dose-sensitivity diagrams) for entire ecosystems like lakes or defined coastal areas. Central aspects concern statistical relationships and causal relationships, clusters and functional groups of interrelated environmental parameters, area- and time compatible data, benefits and drawbacks with the ecometric approach, and the information value of parameters that vary in time and space. The book uses a new and comprehensive set of data on radioactive caesium in lakes (after the Chernobyl accident) to illustrate the various principles and steps in the protocol to establish load diagrammes. The ecometric approach can be used for most pollutants in different types of ecosystems. 168 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Challenges of Astronomy in a unique collection of thirty astronomy experiments ranging from ancient astronomy to cosmology. Each of the experiments contains one or more challenges for the reader. The progression is from the Earth outward through the solar system to the stellar and galactic realm. Topics include the shape of the sky, Stonehenge as a stoneage abacus, determination of the size of the Earth, the distance of the Moon and planets, Kepler's laws, planetary mass and density, the temperatures and atmospheres of planets, the speed of light, the distances of stars, the nature of the quiet and active Sun, photometry and spectroscopy, stars clusters and variable stars, fundamental properties of stars, and Olber's paradox. Challenges of Astronomy is a translation and extensive revision of a German-language resource book for secondary school teachers of science. Physical science teachers will find this edition too a rich resource of experiments to their own milieus, but it is suitable for many other English-language readers too, from northern and southern hemisphere locations. The beginning experiments are suitable for bright high school and non-science major university students while the later experiments which offer increasingly difficult challenges are more suitable for sciences majors. Amateurs with a variety of skills will find this hands-on book entertaining, informative, and useful. 248 pp. Englisch.

It has put common sense back je n'y serais point alle.' Jules Verne where it belongs, on the topmost shelf nCllt to the dusty canister labelled 'discarded non sense'. The series is divergent; therefore we may be able to do something with it. Eric T. Bell O. Heaviside Mathematics is a tool for thought. A highly necessary tool in a world where both feedback and non linearities abound. Similarly, all kinds of parts of mathematics serve as tools for other parts and for other sciences. Applying a simple rewriting rule to the quote on the right above one finds such statements as: 'One service topology has rendered mathematical physics .'; 'One service logic has rendered com puter science .'; 'One service category theory has rendered mathematics .'. All arguably true. And all statements obtainable this way form part of the raison d'etre of this series. 476 pp. Englisch.
