Buch. Condición: Neu. Neuware -The subject of this book is Complex Analysis in Several Variables. This text begins at an elementary level with standard local results, followed by a thorough discussion of the various fundamental concepts of 'complex convexity' related to the remarkable extension properties of holomorphic functions in more than one variable. It then continues with a comprehensive introduction to integral representations, and concludes with complete proofs of substantial global results on domains of holomorphy and on strictly pseudoconvex domains inC', including, for example, C. Fefferman's famous Mapping Theorem. The most important new feature of this book is the systematic inclusion of many of the developments of the last 20 years which centered around integral representations and estimates for the Cauchy-Riemann equations. In particu lar, integral representations are the principal tool used to develop the global theory, in contrast to many earlier books on the subject which involved methods from commutative algebra and sheaf theory, and/or partial differ ential equations. I believe that this approach offers several advantages: (1) it uses the several variable version of tools familiar to the analyst in one complex variable, and therefore helps to bridge the often perceived gap between com plex analysis in one and in several variables; (2) it leads quite directly to deep global results without introducing a lot of new machinery; and (3) concrete integral representations lend themselves to estimations, therefore opening the door to applications not accessible by the earlier methods.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This book presents a unified collection of concepts, tools, and techniques that constitute the most important technology available today for the design and implementation of information systems. The framework adopted for this integration goal is the one offered by the relational model of data, its applica tions, and implementations in multiuser and distributed environments. The topics presented in the book include conceptual modeling of application environments using the relational model, formal properties of that model, and tools such as relational languages which go with it, techniques for the logical and physical design of relational database systems and their imple mentations. The book attempts to develop an integrated methodology for addressing all these issues on the basis of the relational approach and various research and practical developments related to that approach. This book is the only one available today that presents such an inte gration. The diversity of approaches to data models, to logical and physical database design, to database application programming, and to use and imple mentation of database systems calls for a common framework for all of them. It has become difficult to study modern database technology with out such a unified approach to a diversity of results developed during the vigorous growth of the database area in recent years, let alone to teach a course on the subject.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Buch. Condición: Neu. Neuware -The advent of computer aided design and the proliferation of computer aided design tools have been instrumental in furthering the state-of-the art in integrated circuitry. Continuing this progress, however, demands an emphasis on creating user-friendly environments that facilitate the interaction between the designer and the CAD tool. The realization of this fact has prompted investigations into the appropriateness for CAD of a number of user-interface technologies. One type of interface that has hitherto not been considered is the natural language interface. It is our contention that natural language interfaces could solve many of the problems posed by the increasing number and sophistication of CAD tools. This thesis represents the first step in a research effort directed towards the eventual development of a natural language interface for the domain of computer aided design. The breadth and complexity of the CAD domain renders the task of developing a natural language interface for the complete domain beyond the scope of a single doctoral thesis. Hence, we have initally focussed on a sub-domain of CAD. Specifically, we have developed a natural language interface, named Cleopatra, for circuit-simulation post-processing. In other words, with Cleopatra a circuit-designer can extract and manipulate, in English, values from the output of a circuit-simulator (currently SPICE) without manually having to go through the output files produced by the simulator.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Buch. Condición: Neu. Neuware -This book proposes a new approach to circuit simulation that is still in its infancy. The reason for publishing this work as a monograph at this time is to quickly distribute these ideas to the research community for further study. The book is based on a doctoral dissertation undertaken at MIT between 1982 and 1985. In 1982 the author joined a research group that was applying bounding techniques to simple VLSI timing analysis models. The conviction that bounding analysis could also be successfully applied to sophisticated digital MOS circuit models led to the research presented here. Acknowledgments 'me author would like to acknowledge many helpful discussions and much support from his research group at MIT, including Lance Glasser, John Wyatt, Jr. , and Paul Penfield, Jr. Many others have also contributed to this work in some way, including Albert Ruchli, Mark Horowitz, Rich Zippel, Chtis Terman, Jacob White, Mark Matson, Bob Armstrong, Steve McCormick, Cyrus Bamji, John Wroclawski, Omar Wing, Gary Dare, Paul Bassett, and Rick LaMaire. The author would like to give special thanks to his wife, Deborra, for her support and many contributions to the presentation of this research. The author would also like to thank his parents for their encouragement, and IBM for its financial support of t,I-Jis project through a graduate fellowship. THE BOUNDING APPROACH TO VLSI CIRCUIT SIMULATION 1. INTRODUCTION The VLSI revolution of the 1970's has created a need for new circuit analysis techniques.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Buch. Condición: Neu. Neuware -The rapidly burgeoning research of the past two decades on agonist-antagonist analgesics and opioid receptors makes this exhaustive review of opioid anal gesics particularly relevant and timely. After an introductory chapter the additional 12 chapters begin logically with morphine and congeners (4- epoxymorphinans) and end with opioid receptors. All principal chemical types of centrally acting analgesics (including endogenous opioid-like substances) and their antagonists as well as the mixed agonist-antagonists are treated thoroughly, although not always (and for good reason) in historical (chrono logical) order. A chapter on miscellaneous types (atypical structures for the most part) includes the benzimidazoles (etonitazene), aminotetralins (dezocine), tetrahydroisoquinolines (methopholine), and so on. Important aspects and correlations of chemistry, pharmacology, and biochemistry are discussed in depth. Literature citations are numerous. For educators, practicing laboratory scientists, and physicians, this scholarly review by two authors well of opioid analgesics versed in the chemistry, pharmacology, and biochemistry will be informative, stimulating, and thought-provoking. Everette L. May Medical College of Virginia Richmond, VA 23298 v Preface The history of opium predates the written word, although knowledge of its constituents dates back less than 200 years. Over the centuries its popularity for the relief of pain has waxed and waned, until today the opiates are widely recognized as excellent analgesics but with disadvantages that have impaired their use seriously. There is a clear need for a potent analgesic with minimal effects on the respiratory centers and gastrointestinal tract and preferably devoid of dependence liability.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 538 pp. Englisch.

Thus, it was a recurring-and rather infuriating-aspect of the early discussions on infonnation technology that those who participated tended either to ignore or to severely understate the role in infonnation technology of telecommunications. This very fine book by Ken Grover goes a long way toward correcting that misconception. However important the computer and computer-based equipment might be, the role of telecommunications equip ment has also been and continues to be significant. Moreover, as the author brings out, it is going to be even more important. As this enthralling story unfolds the reader will find him or herself continually remarking that there cannot be more-but again and again, there is. Those who are already of the world of telecommunications will, on reading this work, be proud of their colleague. Those who are already of the world of computers will learn a great deal and, it is to be hoped, will in future be fairer toward telecommunications than they have been in the past. Those who are new to the world of information technology will sally forth better balanced than most. 216 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -In any business, the essential element for the successful use of data processing is training. This represents the largest expense both at start-up and as CAD impacts design office procedures other than drafting. Training is also the most difficult cost item to quantify. Even more than the equip ment, training - or retraining in the case of professionals in practice - is the key to increased productivity. Recommendations for specific programs of training are beyond the scope of this paper. Once staff has been retrained to work at higher levels of productivity with data processing equipment, they are more valuable. They will be more difficult to replace. Their new capabilities represent a significant invest ment in modernization, both to the individual design office and to the design profession as a whole. There is a shortage of qualified people with both professional and computer skills. Competition among employers for people with these skills already exists and will probably continueinto the foreseeable future. At the outset of training, an employment agreement is worth consider ing for the well-being of all parties.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Neuware -The authors have provided an overview of the relationships between hormones that are physiologic constituents of the body as well as their pharmacologic use in replacement therapies and related endocrine dys function. Principles of Endocrine Pharmacology concerns itself with the ther apeutic use of hormones, and hormone like substances, or drugs that can act either by suppressing or enhancing the metabolism of certain glands of internal secretion. Other drugs used for nonendocrine ther apies can likewise affect the endocrine system. Endocrine pharmacology emerged in the early 1900s with the use of crude pituitary extracts. By the mid-1900s several investigators had isolated and begun to synthesize hormones or hormonelike substances. Recognizing the limited supply of hormones that could be obtained both from animal sources and human autopsy material, the search for so called hormone substitutes also began early in the 1900s. Recently, re combinant DNA technologies have been used to provide alternative therapeutic sources of human insulin and human growth hormone. Aside from insulin, perhaps no other use of hormonally-active sub stance is better exemplified by those drugs which affect fertility. The synthesis of an orally-effective steroid represented one of the first major breakthroughs in the chemical suppression of ovulation. Since the orally active 19-norsteroids were introduced in the 1950s, several oral contra ceptive steroid preparations have been marketed. Indeed, the advent of oral contraceptives for birth control has led to a renewed interest in endocrine pharmacology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Neuware -This book contains a selection of papers and articles in instrumentation previously pub lished in technical periodicals and journals of learned societies. Our selection has been made to illustrate aspects of current practice and applications of instrumentation. The book does not attempt to be encyclopaedic in its coverage of the subject, but to provide some examples of general transduction techniques, of the sensing of particular measurands, of components of instrumentation systems and of instrumentation practice in two very different environments, the food industry and the nuclear power industry. We have made the selection particularly to provide papers appropriate to the study of the Open University course T292 Instrumentation. The papers have been chosen so that the book covers a wide spectrum of instrumentation techniques. Because of this, the book should be of value not only to students of instrumen tation, but also to practising engineers and scientists wishing to glean ideas from areas of instrumentation outside their own fields of expertise. In recent years instrumentation has emerged as a discipline in its own right rather than as an adjunct to traditional science and engineering disciplines. This development has been driven partly by the needs of industries for new and improved sensing techniques, and partly by new technological developments such as microprocessors, optical fibres and in tegrated silicon sensors which are revolutionising sensing and signal processing practice.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 272 pp. Englisch.

Neuware -After two decades, data processing has finally, and probably forever, found its niche among civil engineering and construction (CEC) professionnals, through word processors, digitizing tables, management software, and increasingly via drawing software and computer-aided design (CAD), recently, robots have even started invading work sites. What are the main trends of CAD and robotics in the field of architecture and civil enginee ring What type of R&D effort do university and industrial laboratories undertake to devise the professional software that will be on the market in the next three to five years These are the issues which will be addressed during this symposium. To this effect, we have planned concurrently an equipment and software show, as well as a twofold conference. Robotic is just starting in the field of civil engineering and construction. A pioneer, the Civil Engineering Departement of Carnegie-Mellon University, in the United States, organized the first two international symposia, in 1984 and 1985 in Pittsburgh. This is the third meeting on the subject (this year, however, we have also included CAD). It constitutes the first large international symposium where CAD experts, specialists in architecture and CEC robotics will meet. From this standpoint, it should be an ideal forum for exchanging views and expe riences on a wide range of topics, and we hope it will give rise to novel applications and new syntheses. This symposium is intented for scientists, teachers, students and also for manufacturers and all CEC professionals.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This was the third meeting in the series of special topical conferences on Non-Metallic materials at low temperatures. The first meeting was in Munich in 1978, the second in Geneva (1980) and so Heidelberg 1984 seemed an obvious time to review some of the hopes and objectives of the earlier meetings. It is also appropriate to consider the changing needs of the cryogenic community and how best the theory and practice of Non-metallic materials can be applied to suit this dynamic young science. The aims and objectives of the International Cryogenic Materials Board in sponsoring this meeting remain the same. Namely, to provide a forum where practicing Engineers can meet with materials suppliers and researchers in an attempt to ensure that a real understanding exists between the two sides of the Cryogenic Materials Community. In this atmosphere, real problems can be addressed together with full discussions of tried and tested practical solutions. It is in this way that knowledge and confidence may grow hand in hand with the logical growth of the industry. 236 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book contains notes for a one-semester course on viscoelasticity given in the Division of Applied Mathematics at Brown University. The course serves as an introduction to viscoelasticity and as a workout in the use of various standard mathematical methods. The reader will soon find that he needs to do some work on the side to fill in details that are omitted from the text. These are notes, not a completely detailed explanation. Furthermore, much of the content of the course is in the problems assigned for solution by the student. The reader who does not at least try to solve a good many of the problems is likely to miss most of the point. Much that is known about viscoelasticity is not discussed in these notes, and references to original sources are usually not give, so it will be difficult or impossible to use this book as a reference for looking things up. Readers wanting something more like a treatise should see Ferry's Viscoelastic Properties of Polymers, Lodge's Elastic Liquids, the volumes edited by Eirich on Rheology, or any issue of the Transactions of the Society of Rheology. These works emphasize physical aspects of the subject. On the mathematical side, Gurtin and Sternberg's long paper On the Linear Theory of Viscoelasticity (ARMA II, 291 (I962» remains the best reference for proofs of theorems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book is based on the author's Ph.D. dissertation[56]. The the sis research was conducted while the author was a graduate student in the Department of Computer Science at Rutgers University. The book was pre pared at the University of Massachusetts at Amherst where the author is currently an Assistant Professor in the Department of Computer and Infor mation Science. Programs that learn concepts from examples are guided not only by the examples (and counterexamples) that they observe, but also by bias that determines which concept is to be considered as following best from the ob servations. Selection of a concept represents an inductive leap because the concept then indicates the classification of instances that have not yet been observed by the learning program. Learning programs that make undesir able inductive leaps do so due to undesirable bias. The research problem addressed here is to show how a learning program can learn a desirable inductive bias.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 188 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The 37th Annual Denver Conference on Applications of X-Ray Analysis was held August 1-5, 1988, at the Sheraton Steamboat Resort and Conference Center, Steamboat Springs, Colorado. As usual, alternating with x-ray diffraction, the emphasis this year was x-ray fluorescence, but as has been the pattern for several occasions over the last few years, the Plenary Session did not deal with that subject, specifically. In an attempt to introduce the audience to one of the new developments in x-ray analysis, the title of the session was 'High Brilliance Sources/Applications,' and dealt exclusively with synchrotron radiation, a topic which has made a very large impact on the x-ray community over the last decade. As the organizer and co-chairman of the Plenary Session (with Paul Predecki), it is my responsibility to report on that session here. The Conference had the privilege of obtaining the services of some of the preeminent practitioners of research using this remarkable x-ray source; they presented the audience with unusually lucid descriptions of the work which has been accomplished in the development and application of the continuous, high intensity, tunable, polarized and collimated x-rays available from no facility other than these specialized storage rings. The opening lecture (and I use that term intentionally) was an enthusiastic description of 'What is Synchrotron Radiation ' by Professor Boris Batterman of Cornell University and the Cornell High Energy Synchrotron Sourc(!

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This work, Essential Endocrinology: A Primer for Nonspecialists, is written with dual purposes in mind: first, to provide a framework of basic endocrinology and diabetology to the medical student, and second, to provide a quick, con cise, and handy 'guide' to the junior residents in their early years of training who wish to obtain a working knowledge about endocrine disorders that affect their patients. One of the outstanding advantages of being a teacher of en docrinology to students and junior residents is that it bestows a perspective from a unique vantage point. Books written for the junior members of our profession have suffered from extremes of caliber, ranging from excellence beyond their comprehension to insufferable mediocrity. Textbooks in en docrinology that are simple enough to cover the principles of that speciality and yet comprehensive enough without treading into controversial quicksand are few and far between. This book is aimed at filling that gap and is written with no other criterion than simplifying a complex subject matter. From this touchstone, the work has never really departed. A decade of experience as a teacher and physician in the field of endo crinologyhas impressed on me that the process of 'simplification' rests on four basic principles: an understanding of endocrine concepts, the application of these concepts to the understanding of diseases, the transference of knowl edge to clinical situations, and the integration of the patient with the labo ratory, the ultimate testing ground where clinical diagnoses stand or fall. 556 pp. Englisch.
