Buch. Zustand: Neu. Neuware - The VHSIC Hardware Description Language (VHDL) provides a standard machine processable notation for describing hardware. VHDL is the result of a collaborative effort between IBM, Intermetrics, and Texas Instruments; sponsored by the Very High Speed Integrated Cir cuits (VHSIC) program office of the Department of Defense, beginning in 1981. Today it is an IEEE standard (1076-1987), and several simulators and other automated support tools for it are available commercially. By providing a standard notation for describing hardware, especially in the early stages of the hardware design process, VHDL is expected to reduce both the time lag and the cost involved in building new systems and upgrading existing ones. VHDL is the result of an evolutionary approach to language devel opment starting with high level hardware description languages existing in 1981. It has a decidedly programming language flavor, resulting both from the orientation of hardware languages of that time, and from a ma jor requirement that VHDL use Ada constructs wherever appropriate. During the 1980's there has been an increasing current of research into high level specification languages for systems, particularly in the software area, and new methods of utilizing specifications in systems de velopment. This activity is worldwide and includes, for example, object oriented design, various rigorous development methods, mathematical verification, and synthesis from high level specifications. VAL (VHDL Annotation Language) is a simple further step in the evolution of hardware description languages in the direction of applying new methods that have developed since VHDL was designed.…

Buch. Zustand: Neu. Neuware - Artificial Neural Networks have captured the interest of many researchers in the last five years. As with many young fields, neural network research has been largely empirical in nature, relyingstrongly on simulationstudies ofvarious network models. Empiricism is, of course, essential to any science for it provides a body of observations allowing initial characterization of the field. Eventually, however, any maturing field must begin the process of validating empirically derived conjectures with rigorous mathematical models. It is in this way that science has always pro ceeded. It is in this way that science provides conclusions that can be used across a variety of applications. This monograph by Michael Lemmon provides just such a theoretical exploration of the role ofcompetition in Artificial Neural Networks. There is 'good news' and 'bad news' associated with theoretical research in neural networks. The bad news isthat such work usually requires the understanding of and bringing together of results from many seemingly disparate disciplines such as neurobiology, cognitive psychology, theory of differential equations, largc scale systems theory, computer science, and electrical engineering. The good news is that for those capable of making this synthesis, the rewards are rich as exemplified in this monograph.…

Buch. Zustand: Neu. Neuware - Gallium Arsenide technology has come of age. GaAs integrated circuits are available today as gate arrays with an operating speed in excess of one Gigabits per second. Special purpose GaAs circuits are used in optical fiber digital communications systems for the purpose of regeneration, multiplexing and switching of the optical signals. As advances in fabrication and packaging techniques are made, the operat ing speed will further increase and the cost of production will reach a point where large scale application of GaAs circuits will be economical in these and other systems where speed is paramount. This book is written for students and engineers who wish to enter into this new field of electronics for the first time and who wish to embark on a serious study of the subject of GaAs circuit design. No prior knowledge of GaAs technology is assumed though some previous experience with MOS circuit design will be helpful. A good part of the book is devoted to circuit analysis, to the extent that is possible for non linear circuits. The circuit model of the GaAs transistor is derived from first principles and analytic formulas useful in predicting the approxi mate circuit performance are also derived. Computer simulation is used throughout the book to show the expected performance and to study the effects of parameter variations.…

Buch. Zustand: Neu. Neuware - If one envisages neuroscience as a pyramid, with the more mole- lar disciplines forming the base and the more integrative d- ciplines positioned above, then neuropsychology clearly would be near the tip. Neuropsychology seeks to find order in the ultimate product of all neural systems, namely behavior, and to relate that product to its neural substrate. Relationships between brain and behavior are sought, but reductionistic explanations are eschewed. Attempting to 'explain' complex behaviors in terms of neuronal activity is no more satisfying than attempting to 'explain' artificial intelligence in terms of voltages within a computer's central pr- essing unit. If one is to comprehend the functioning of either the brain or the digital computer, one must know something about not only the structure and mechanics of the device, but also the prin- ples according to which components of the device are organized and the context in which the device is operating (e.g., environm- tal inputs and stored information).…

Buch. Zustand: Neu. Neuware - Higher circuit densities, increasingly more complex application ohjectives, and advanced packaging technologies have suhstantially increased the need to incorporate defect-tolerance and fault-tolerance in the design of VLSI and WSI systems. The goals of defect-tolerance and fault-tolerance are yield enhancement and improved reliahility. The emphasis on this area has resulted in a new field of interdisciplinary scientific research. I n fact, advanced methods of defect/fault control and tolerance are resulting in enhanced manufacturahility and productivity of integrated circuit chips, VI.SI systems, and wafer scale integrated circuits. In 1987, Dr. W. Moore organized an 'International Workshop on Designing for Yield' at Oxford University. Edited papers of that workshop were published in reference [II. The participants in that workshop agreed that meetings of this type should he con tinued. preferahly on a yearly hasis. It was Dr. I. Koren who organized the 'IEEE Inter national Workshop on Defect and Fault Tolerance in VLSI Systems' in Springfield Massachusetts the next year. Selected papers from that workshop were puhlished as the first volume of this series [21.…

Buch. Zustand: Neu. Neuware - Over the past decade, techniques have been developed and implemented to observe metabolism noninvasively in localized regions of intact, living experimental animals and humans through the use of magnetic resonance spectroscopy (MRS). At the same time, magnetic resonance imaging (MRI) techniques developed in the 1970s and refined in this decade have been increasingly applied as a powerful clinical tool to probe human anatomy. Because of the unusual metabolic and physiologic characteristics of malignant tissues, oncology has been one of the primary focuses of the application of both MRS and MRI. Although considerable progress has been made in oncologic applications of magnetic resonance (MR), further research is needed to realize the full potential of MR in this area. Consequently, the 21st Annual Detroit Cancer Symposium entitled 'Magnetic Resonance in Experimental and Clin ical Oncology' was organized to provide a forum for researchers in the field to report the state of the art of MRS and MRI in oncol ogy, to discuss future goals for MRS and MRI in oncology, and to define the research needed to meet those goals. The major emphasis of the symposium was on MRS due to both the recent widespread availability of clinical MRS instrumentation and the extensive amount of animal MRS research performed over the past half decade.…

Buch. Zustand: Neu. Neuware - construction. Naturally, we are open to suggestions from all readers of, and contributors to, the series regarding its approach and content. Finally, I would like to thank all those who have helped the launch of this series. The encouraging response received from authors who have contributed the forthcoming volumes and from the subscribers to the series has indicated the need for such a publication. Homa Motamen-Scobi London December 1987 Preface In 1990 both OPEC and the OECD will celebrate their thirtieth anntvers aries. OPEC was founded - rather unnoticed - by oil-producing countries still struggling to gain control over national petroleum resources. Future members were still under colonial rule. The foremost aim of the new organization - years before it was able to make metropolitan newspaper headlines - was stabilizing oil prices. Stability in those days meant prevent ing oil prices from falling in real terms. The OECD was formed by mostly mature industrial economies marking the normalization of the postwar international economy after years of reconstruction, strict trade regulations, etc. The aim of the new organization was to promote 'the highest sustainable growth and employment' in member countries. Incidentally, 1960 was also the year which gave birth to a more loosely defined block in the world community, namely the underdeveloped countries, qS the African colonial empires finally broke up. The two organizations became adversaries in the 1970s in the power struggle over the energy flows of the world.…

Buch. Zustand: Neu. Neuware - The first version of this book, Packaging Materials and Containers was published in 1967 and was revised extensively ten years later under the title The Packaging Media. Some thirty or so authors were involved in producing the initial texts for these books, and I must acknowledge their material, much of which is still valid. It is now thirteen years since The Packaging Media-high time to take stock and incorporate the considerable advances in materials, forms, techniques and machinery that have taken place. In 1977, wherever possible, we asked the original authors to carry out the revisions, but retirements and job changes have now eliminated over twenty of the original authors. We have therefore appointed an Editorial Board to advise on this more extensive revision, and I wish to thank them for their detailed and helpful assistance: Dr C. J. Mackson and Professor Y. Dagel for general comments and guidance on the overall plan and, in particular, the Introduction (chapter 1); Graham Gordon and Harri Mostyn for assistance with much of Part D on Distribution Packages, and Dennis Hine and Susan Selke for their work in respect of paperboard and plastics retail packaging, respectively. A major contribution was made by the seventh member of the Editorial Board, David Osborne, who advised in the area of glass.…

Buch. Zustand: Neu. Neuware - This volume, SCIENCE OF SINTERING: NEW DIRECTIONS FOR MATERIALS PROCESSING AND MICROSTRUCTURAL CONTROL, contains the edited Proceedings of the Seventh World Round Table Conference on Sintering, held in Herceg-Novi, Yugoslavia, Aug. 28 - Sept. 1, 1989. It was organized by the International Institute for the Science of Sintering (IISS), headquartered in Belgrade, Yugoslavia. Every fourth year since 1969, the Institute has organized such a Round Table Conference on Sintering; each has taken place at some selected location within Yugoslavia. A separate series of IISS Topical Sintering Symposia (Summer Schools) have also been held at four year intervals, but they have been offset by about two years, so they occur between the main Conferences. As a rule, the Topical Sintering Symposia have been devoted to more specific topics and they also take place in different countries. The aim of these Conferences and their related 'Summer Schools' has been to bring together scientists from all over the world who work in various fields of science and technology concerned with sintering and sintered materials. A total of seven IISS Conferences have been held over the period 1969-1989, and they have been supplemented by the four Topical Sintering Symposia held in Yugoslavia, Poland, India and Japan (in 1975, 1979, 1983 and 1987, respectively). This most recent five day Conference addressed the fundamental scientific background as well as the technological state-of-the-art pertinent to science of sintering and high technology sintered materials.…

Taschenbuch. Zustand: Neu. Neuware - The papersin this volume are as a resultofcontributions given at the NATO Advanced Study Institute heldat L1andinam Building, University CollegeofWales, Aberystwyth, 10 - 23 September 1989. The Institute considered the physical and chemical propertiesof a variety ofcolloidal systems ranging from simple micellar solutions to concentrated colloidal dispersions. The purpose ofthe NATO Advanced Study Institute was to create a forum so that research scientists working in different areas concerned with colloid science could interact. The emphasL oft1'l. ;: contributions were on the interpretation ofthe different experimental and theoretical approach to give information on the structure, dynamics and equilibrium propertiesofthese systems. The application ofseveral different techniques in colloid science have been described; new developments and perspectives have been covered by several authors. The present volume reviews the current stale ofthe art in this area and it is hoped that it will be used as an incentive for further studies particularlywith reference to new areas ofresearch.
