Buch. Condizione: Neu. 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.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -As in all other fields of astronomy, progress in instrumentation and observational techniques has in recent years brought a wealth of new information about the sun. This introduction presents a complete overview of solar physics, of what we know and would like to know. The increasing number of observations of solar pheno- mena on neighbouring stars makes this book valuable not only for students specializing in solar physics but also for researchers interested in stellar structure and the solar-stellar connection. 408 pp. Englisch.

Buch. Condizione: Neu. 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.

Buch. Condizione: Neu. Neuware -Textbooks, even excellent ones, are a reflection of their times. Form and content of books depend on what the students know already, what they are expected to learn, how the subject matter is regarded in relation to other divisions of mathematics, and even how fashionable the subject matter is. It is thus not surprising that we no longer use such masterpieces as Hurwitz and Courant's Funktionentheorie or Jordan's Cours d'Analyse in our courses. The last two decades have seen a significant change in the techniques used in the theory of functions of one complex variable. The important role played by the inhomogeneous Cauchy-Riemann equation in the current research has led to the reunification, at least in their spirit, of complex analysis in one and in several variables. We say reunification since we think that Weierstrass, Poincare, and others (in contrast to many of our students) did not consider them to be entirely separate subjects. Indeed, not only complex analysis in several variables, but also number theory, harmonic analysis, and other branches of mathematics, both pure and applied, have required a reconsidera tion of analytic continuation, ordinary differential equations in the complex domain, asymptotic analysis, iteration of holomorphic functions, and many other subjects from the classic theory of functions of one complex variable. This ongoing reconsideration led us to think that a textbook incorporating some of these new perspectives and techniques had to be written.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 668 pp. Englisch.

Buch. Condizione: Neu. Neuware -What can the philosophy of language learn from the classical Indian philosophical tradition As recently as twenty or thirty years ago this question simply would not have arisen. If a practitioner of analytic philosophy of language of that time had any view of Indian philosophy at all, it was most likely to be the stereotyped picture of a gaggle of navel gazing mystics making vaguely Bradley-esque pronouncements on the oneness of the one that was one once. Much work has been done in the intervening years to overthrow that stereotype. Thanks to the efforts of such scholars as J. N. Mohanty, B. K. Matilal, and Karl Potter, philoso phers working in the analytic tradition have begun to discover something of the range and the rigor of classical Indian work in epistemolgy and metaphysics. Thus for instance, at least some recent discussions of personal identity reflect an awareness that the Indian Buddhist tradition might prove an important source of insights into the ramifications of a reductionist approach to personal identity. In philosophy of language, though, things have not improved all that much. While the old stereotype may no longer prevail among its practitioners, I suspect that they would not view classical Indian philoso phy as an important source of insights into issues in their field. Nor are they to be faulted for this.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

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 a novel exposition of the traditional workhorses of statistics: analysis of variance and regression. The key feature is that these tools are viewed in their natural mathematical setting, the geometry of finite dimensions. The Authors To introduce ourselves, Dave Saville is a practicing statistician working in agricultural research; Graham Wood is a university lecturer involved in the teaching of statistical methods. Each of us has worked for sixteen years in our current field. Features of the Book People like pictures. One picture can present a set of ideas at a glance, while a series of pictures, each building on the last, can unify a wealth of ideas. Such a series we present in this text by means of a systematic geometric approach to the presentation of the theory of basic statistical methods. This approach fills the void between the traditional extremes of the 'cookbook' approach and the 'matrix algebra' approach, providing an elementary but at the same time rigorous view of the subject. It combines the virtues of the traditional methods, while avoiding their vices.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 584 pp. Englisch.

Buch. Condizione: Neu. Neuware -Mathematicians and non-mathematicians alike have long been fascinated by geometrical problems, particularly those that are intuitive in the sense of being easy to state, perhaps with the aid of a simple diagram. Each section in the book describes a problem or a group of related problems. Usually the problems are capable of generalization of variation in many directions. The book can be appreciated at many levels and is intended for everyone from amateurs to research mathematicians.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

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 -The origins of this book probably go back to Gordon Allport's seminar in social psychology at Harvard during the late 1940s and to the invitation from Gardner Lindzey, some years later, to contribute a section on 'Sympathy and Empathy' to the International Encyclopedia of the Social Sciences (1968). Since those early beginnings, the book has been 'in the process of becoming. ' During that time I have benefited greatly from the knowledge and assistance of many colleagues, especially the following, who read and commented upon portions of the manuscript: Raymond Gastil, the late Joseph Katz, David McClelland, Jitendra Mohanty, Paul Mussen, Richard Solomon, and Bernard Weiner. To Kenneth Merrill for a close reading of the Hume material and to M. Brewster Smith for a careful reading of and suggestions on Chapters 7 and 8, I am especially indebted. Beverly Joyce withstood constant interruptions to provide much-needed library assistance, and Vivian Wheeler gave generously of her excellent editorial experience and knowledge. A fellowship at the Battelle Research Center in Seattle and an appointment as a visiting scholar at Harvard were of incalculable help, providing opportunity, stimulation, and freedom from teaching responsibilities. To all of the above I am deeply indebted. Just a few words about the organization of this book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Buch. Condizione: Neu. Neuware - Paul Halmos will celebrate his 75th birthday on the 3rd of March 1991. This volume, from colleagues, is an expression of affection for the man and respect for his contributions as scholar, writer, and teacher. It contains articles about Paul, about the times in which he worked and the places he has been, and about mathematics. Paul has furthered his profession in many ways and this collection reflects that diversity. Articles about Paul are not biographical, but rather tell about his ideas, his philosophy, and his style. Articles about the times and places in which Paul has worked describe people, events, and ways in which Paul has influenced students and colleagues over the past 50 years. Articles about mathematics are about all kinds of mathematics, including operator theory and Paul's research in the subject. This volume represents a slice of mathematical life and it shows how many parts of mathematics Paul has touched. It is fitting that this volume has been produced with the support and cooperation of Springer-Verlag. For over 35 years, Paul has contributed to mathematics publishing as founder and editor of many outstanding series.

Buch. Condizione: Neu. Neuware -Since the publication of our earlier book on transition metal mediated organic synthesis, \* there has been a widespread increase of interest in this topic, and transition metal based methodology has become firmly established in many areas of organic chemistry. The direct, catalytic formation of organic carbonyl compounds using carbon monoxide as the source of the carbonyl group has seen exceptional progress, and this carbonylation chemistry is being used increasingly in research and on a larger scale for fine chemicals production. In view of these developments, there is a need for a modem, practi cally oriented book dealing with transition metal based carbonylation chemistry. The present monograph should help fulfill this need, since it is intended specifically to foster the adoption of catalytic carbonylation as a general tool in synthetic organic chemistry. It deals exclusively with reactions involving the interconversion of carbon monoxide and organic carbonyl compounds, and although the majority of the reactions discussed involve catalytic formation of carbonyl compounds, potentially valuable syntheses requiring stoichiometric quantities of transition metal are also included. In addition, a chapter is devoted to the remarkably useful reverse transformation (decarbonylation), in which an organic carbonyl group is eliminated in the form of carbon monoxide.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Englisch.

Buch. Condizione: Neu. Neuware -Despite, or perhaps better by virtue of, its very brevity, Appearance and Sense is a difficult text to read and understand, particularly if we make the attempt independently of Husserl's Ideas I. This is certainly at least in part owing to the intent behind Shpet's work. On the one hand it strives to present Husserl' s latest views to a Russian philosophical audience not yet conversant with and, in all likelihood, not even aware of, his transcendental idealist turn. With this aim any reading would perforce be exacting. Yet, on the other hand, Shpet has made scant concession to his public. Indeed, his text is even more compressed, especially in the crucial areas dealing with the sense-bestowing feature of consciousness, than Husserl' s own. For all that, Shpet has not bequeathed to us simply an abbreviated paraphrase nor a selective commentary on Ideas I, although at many points it is just that. Rather, the text on the whole is a critical engagement with Husserl' s thought, where Shpet among other things refonnulates or at least presents Husserl's phenomenology from the perspective of hoping to illuminate a traditional philosophical problem in a radical manner. Since Husserl's text was published only in 1913 and Shpet's appeared sometime during 1914, the latter must have been conceived, thought through, and written in remarkable haste. Indeed, Shpet had already finished a first draft and was busy with a revision of it by the end of 1913.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -During the last decades the knowledge of the magnetic properties of the d transition elements and of their metallic alloys and compounds has increased widely. The improvement of preparation techniques for well-defined substances, the development of sophisticated measuring methods and above all the drive to obtain more insight in the origin of magnetic interactions in solids have resulted in the publication of many specific magnetic properties for an abundance of all kinds of metallic materials. The data assembled in this booklet are selected from the comprehensive compilation of magnetic and related properties of metals in the Landolt-Bornstein New Series Group III sub volumes 19a, band c. It has been attempted to include preferentially those properties which are of a basic character and which therefore are most often needed by scientists active in the field of solid state magnetism. In the field of magnetism, there is a gradual transition from the use of cgs/emu units to SI units. It was, however, not intended to represent all data in the units of one system, regardless of how nice this would have been from a systematic point of view. Instead, mostly preference was given to the system of units that was originally used by the authors whose work is quoted. Thus cgs/ emu units occur most frequently. Of colirse the user of the tables and figures is helped in several ways to convert the data to the units which he is most familiar with, see, e. g.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Buch. Condizione: Neu. Neuware -Pulsed power technology, in the simplest of terms, usually concerns the storage of electrical energy over relatively long times and then its rapid release over a comparatively short period. However, if we leave the definition at that, we miss a multitude of aspects that are important in the ultimate application of pulsed power. It is, in fact, the application of pulsed power technology to which this series of texts will be focused. Pulsed power in today's broader sense means 'special power' as opposed to the tra ditional situation of high voltage impulse issues related to the utility industry. Since the pulsed power field is primarily application driven, it has principally an engineering flavor. Today' s applications span those from materials processing, such as metal forming by pulsed magnetic fields, to other varied applications, such as psy chedelic strobe lights or radar modulators. Very high peak power applications occur in research for inertial confinement fusion, the Strategic Defense Initiative and other historical defense uses. lri fact it is from this latter direction that pulsed power has real ized explosive growth over the past half century. Early thrusts were in electrically powered systems that simulated the environment or effects of nuclear weapons detonation. More recently it is being utilized as prime power sources for directed energy weapons, such as lasers, microwaves, particle beam weapons, and even mass drivers (kinetic energy weapons).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 598 pp. Englisch.

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 - In recent years various industries have demanded not only greater use of polymeric materials but also the development of polymeric materials with specific properties. Major users include the automotive and transport industries, electrical and electronics industries, and the packaging industry. Following the success of Speciality Polymers, Dr Dyson's book provides an overview of the main types of polymeric materials used in engineering, and discusses their applications - both practical and potential.

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.

Buch. Condizione: Neu. Neuware -by JULIEN IE HOFFMAN One of the earliest coronary physiologists was Scaramucci who, in 1695, postu lated that during systole the contracting myocardium inhibited coronary blood flow. Since then, the many contributions that have been made to our knowledge of the coronary circulation can be arbitrarily divided into three phases based on advances in technical methods. The early phase of research into the coronary circulation, done with great difficulty with crude methods, may be regarded as ending in the 1940s, and it included major discoveries made by such well known investigators as Georg von Anrep, Ernest Starling, Carl Wiggers, and Louis Katz, who formulated much of our basic understanding of the field. After 1940, the field of coronary physiology entered a new phase when instruments for high fidelity registration of coronary flow and pressure became available. This era was domi nated by Donald Gregg who combined careful attention to the function of these instruments (some of which he helped to develop) with an extraordinary ability to discern mechanisms from apparently minor changes in coronary flow and pressure patterns. His book 'The Coronary Circulation in Health and Disease' set a new standard in the field. After 1960, techniques for measuring regional myocardial blood flow became available, and enabled a large group of eminent investigators to make major advances in understanding the physiology and pathophysiology of myocardial blood flow.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.
