Buch. Condizione: Neu. Neuware - The last twenty years have seen major advances in the electronics industry. Perhaps the most significant aspect of these advances has been the significant role that electronic equipment plays in almost all product markets. Even though electronic equipment is used in a broad base of applications, many future applications have yet to be conceived. This versatility of electron ics has been brought about primarily by the significant advances that have been made in integrated circuit technology. The electronic product user is rarely aware of the integrated circuits within the equipment. However, the user is often very aware of the size, weight, mod ularity, maintainability, aesthetics, and human interface features of the product. In fact, these are aspects of the products that often are instrumental in deter mining its success or failure in the marketplace. Optimizing these and other product features is the primary role of Electronic Equipment Packaging Technology. As the electronics industry continues to pro vide products that operate faster than their predecessors in a smaller space with a reduced cost per function, the role of electronic packaging technology will assume an even greater role in the development of cost-effective products.

Buch. Condizione: Neu. Neuware - 1. 1 INTRODUCTION The final chapter of my Personal Income Distribution, a Hulticapability Theory (Hartog, 1981a) carried as its motto: 'Oh richness of the unfinished'. It concluded a book in which labor services were decomposed into services arising from different capabilities. Individuals were supposed to command stocks of capabilities and to decide on the utilization rates of these capabilities, by balanc ing efforts and rewards. The optimal capability bundle they so defined was to be realized by picking the job that just required this bundle. To derive analytical implications on the structure of the labor market and on the distribution of labor earnings, the key assumption was made that arbitrage in capability supply was possible, i. e. , that effectively capabilities could be sold separ ately and carried a uniform unit price throughout the labor market. While many interesting analytical and empirical results followed, there was also an indication from empirical testing that an earnings function linear in capabilities could be outperformed by a non-linear func- 2 CAPABILITIES, ALLOCATION AND EARNINGS tion, and that the arbitrage assumption might be un tenable. This book attempts to harvest a little from the richness of the unfinished that was left. It returns to some of the old topics and adds some new ones, in a more general model that no longer imposes the assumption that capabilities can be treated as if they can be unbundled. It also draws on new datasets to explore the issues empirically.

Buch. Condizione: Neu. Neuware - Bacteria in a test tube and humans on our planet follow the same population curve as time elapses. We on this earth, largely through control of disease, are rapidly ap proaching maximum population, and through energy demands are using up our resour ces and accumulating wastes. We have come to realize the danger of a maturing system but have made essential ly no impact in mitigating or preventing the problems we face. While we have been able to change the world we live in, most of our effects have been to degrade the planet. We have nibbled away at the quality of the atmosphere for centuries and the ac cumulated damage has resulted in changing the world's climate at an ever-increasing rate. We now face the possibility of higher average temperatures over most of our planet, changing patterns of rainfall, rising sea levels, aggravated storm systems and a myriad of social effects.

Buch. Condizione: Neu. Neuware - In recent years there have been major advances in the fields of cardiovascular nuclear medicine and cardiac magnetic resonance imaging. In nuclear cardiology more adequate tomographic systems have been designed for routine cardiac use, as well as new or improved quantitative analytic software packages both for planar and tomographic studies implemented on modern state-of-the-art workstations. In addition, artificial intelligence techniques are being applied to these images in attempts to interpret the nuclear studies in a more objective and reproducible manner. Various new radiotracers have been developed, such as antimyosin, labeled isonitriles, metabolic compounds, etc. Furthermore, alternative stress testing with dipyridamole and dobutamine has received much attention in clinical cardiac practice. Magnetic resonance imaging is a relative newcomer in cardiology and has already shown its merits, not only for anatomical information but increasingly for the functional aspects of cardiac performance. This book covers almost every aspect of quantitative cardiovascular nuclear medicine and magnetic resonance imaging. It will assist the nuclear medicine physician, the radiologist, the physicist/image processing specialist and the clinical cardiologist in understanding the nuclear medicine techniques used in cardiovascular medicine, and in increasing our knowledge of cardiac magnetic resonance imaging.

Buch. Condizione: Neu. Neuware - Postsecondary educational institutions in the United States are facing increasing financial stress and waning public support. Unless these trends can be changed, higher education can be expected to stagnate. What, if anything, can be done As a starting point, advocates of higher education need to more fully recognize the issues associated with the economic mission of higher education and how this mission gets translated into individual student gains, regional growth, and social equity. This requires an understanding of the relationship between the outcomes of higher education and measures of economic productivity and well-being. This volume addresses topics related to the role of postsecondary education in microeconomic development within the United States. At tention is given to the importance of colleges and universities 'in the enhancement of individual students and in the advancement of the com munities and states within which they work. Although several of the chapters in this volume are aimed at research/teaching universities, much of what is presented throughout can be generalized to all of postsecondary education. Little attention, however, is given to the role of higher education in the macroeconomic development of the United States; this topic is covered in our related book, American Higher Education and National Growth.

Buch. Condizione: Neu. Neuware - Our understanding of inflammation has increased rapidly in recent years, due in large part to the impact of molecular biology and gene identification and cloning. This book brings together ideas from a number of different biochemical disciplines which are frequently not integrated. The first chapter gives a visual overview of the subject; the remaining chapters are organized into three themes: the affector molecules, the regulatory components and the processes of inflammation itself. This book is essential reading for the busy physician or pathologist who wants to be up-to-date with the latest developments in immunology as they affect the diagnosis and treatment of many conditions.

Buch. Condizione: Neu. Neuware - Over the last twenty years, automation and robotics have played an increasingly important role in a variety of application domains including manufacturing, hazardous environments, defense, and service industries. Space is a unique environment where power, communications, atmospheric, gravitational, and sensing conditions impose harsh constraints on the ability of both man and machines to function productively. In this environment, intelligent automation and robotics are essential complements to the capabilities of humans. In the development of the United States Space Program, robotic manipulation systems have increased in importance as the complexity of space missions has grown. Future missions will require the construction, maintenance, and repair of large structures, such as the space station. This volume presents the effords of several groups that are working on robotic solutions to this problem. Much of the work in this book is related to assembly in space, and especially in-orbit assembly of large truss structures. Many of these so-called truss structures will be assembled in orbit. It is expected that robot manipulators will be used exclusively, or at least provide partial assistance to humans. Intelligent Robotic Systems for Space Exploration provides detailed algorithms and analysis for assembly of truss structure in space. It reports on actual implementations to date done at NASA's Langley Research Center. The Johnson Space Center, and the Jet Propulsion Laboratory. Other implementations and research done at Rensselaer are also reported. Analysis of robot control problems that are unique to a zero-gravity environment are presented.

Buch. Condizione: Neu. Neuware - Polymers continue to show almost amazing versatility. We have always known that polymers could be used for trinkets, toys and dishes. Now, however, we are no longer surprised to encounter these adaptable mate rials in almost every place we look. We find them in our cars, tools, electronic devices, building materials, etc. The use of polymeric mate rials in medicine is also well documented in previous books by one of the Editors (Gebelein) and by others. Likewise, the use of polymeric mate rials in pharmaceutical applications, especially in controlled release systems, is also well established. Nevertheless, the use of these ubiquitous chemicals is far less ob vious in the field of cosmetics, although modern cosmetic preparations rely heavily on polymers and this trend is certain to increase. This book brings together much of the basic information on polymers in cosmetics and compares this usage with similar applications in pharmaceutical and medical applications. Cosmetics, like medicine and pharmacy, dates back to antiquity. We can find uses of perfumes, balms and ointments in various old books, such as the Bible. For example, the use of ointments and balms is noted more than thirty eight times, and perfumes and related materials are cited at least twenty nine times in the Bible.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There are many ways of introducing the concept of probability in classical, i. e, deter ministic, physics. This work is concerned with one approach, known as 'the method of arbitrary funetionJ. ' It was put forward by Poincare in 1896 and developed by Hopf in the 1930's. The idea is the following. There is always some uncertainty in our knowledge of both the initial conditions and the values of the physical constants that characterize the evolution of a physical system. A probability density may be used to describe this uncertainty. For many physical systems, dependence on the initial density washes away with time. Inthese cases, the system's position eventually converges to the same random variable, no matter what density is used to describe initial uncertainty. Hopf's results for the method of arbitrary functions are derived and extended in a unified fashion in these lecture notes. They include his work on dissipative systems subject to weak frictional forces. Most prominent among the problems he considers is his carnival wheel example, which is the first case where a probability distribution cannot be guessed from symmetry or other plausibility considerations, but has to be derived combining the actual physics with the method of arbitrary functions. Examples due to other authors, such as Poincare's law of small planets, Borel's billiards problem and Keller's coin tossing analysis are also studied using this framework. Finally, many new applications are presented. 168 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains most of the papers presented at theworkshop on research directions in high-level parallelprogramming languages, held at Mont Saint-Michel, France, inJune 1991. The motivation for organizing this workshop camefrom the emergence of a new class of formalisms fordescribing parallel computations in the last few years.Linda, Unity, Gamma, and the Cham are the most significantrepresentatives of this new class. Formalisms of this familypromote simple but powerful language features for describingdata and programs. These proposals appeared in differentcontexts and were applied in different domains, and the goalof the workshop was to review the status of this new fieldand compare experiences. The workshop was organized intofour main sessions: Unity, Linda, Gamma, and ParallelProgram Design. The corresponding parts ofthe volume areintroduced respectively by J. Misra, D. Gelernter, D. LeMtayer, and J.-P. Ban tre. 400 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Presentation Many economic problems, as equilibrium models, input-output analysis, rational behaviour, etc. , are usually modelled in terms of operators in Euclidean spaces. This monograph deals with the analysis of a number of formal problems involving this kind of operators (with particular reference to complementarity problems and variational inequalities), and their applications to distributive problems and equilibrium models. Thus the purpose of this work is to provide a set of new results on the solvability of those problems, and a number of economic applications that will illustrate the interest of these results in economics. It is worth stressing from the very begining that our analysis concentrates on the existence (and in some cases optimality) of solutions. That is what is meant here by solvability (in particular, nothing will be said with respect to the uniqueness, stability, sensitivity analysis or computation of solutions). The results on the solvability of operator problems presented here, were actually arrived at as a way of solving specific economic models. Yet we are going to relate this case by somehow reversing the way it happened, that is, starting with the formal results and then presenting a number of economic models which appear as applications of VIII these formal results. The rationale for this approach is twofold. First, it provides a neat track via which to go through the whole work. Then, because I would like to emphasize the interest of complementarity and variational inequalities problems in economic modelling. 184 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -New composite materials and semi-fabricates, as disparate in their nature as solid multilaminates and powder compacts, have been steadily increasing in importance. Their application to a variety of industrial situations is being made easier by the considerable development of conventional manufacturing techniques which fulfil many of the requirements imposed on such materials. At the same time, however, the degree of their exploitation can be limited by, either the inadequate final product properties, or simply - as in the case of particulate matter - by the inability of these techniques to produce significant quantities of the composite. For these reasons, combined with the ever increasing demand for highly sophisticated composites, attention has been focused on the dynamic manufacturing methods. Not only do they extend the range of the available routes, but they also offer the possibility of achieving chemical and/or structural syntheses of new materials from either the elemental or complex constituents. What is more, these techniques often tend to ensure integral bonding of the elements of the structure and they thus enhance the mechanical properties of the composite. 472 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book mainly discusses the representation theory of the special linear group 8L(2, 1R), and some applications of this theory. In fact the emphasis is on the applications; the working title of the book while it was being writ ten was 'Some Things You Can Do with 8L(2). ' Some of the applications are outside representation theory, and some are to representation theory it self. The topics outside representation theory are mostly ones of substantial classical importance (Fourier analysis, Laplace equation, Huyghens' prin ciple, Ergodic theory), while the ones inside representation theory mostly concern themes that have been central to Harish-Chandra's development of harmonic analysis on semisimple groups (his restriction theorem, regularity theorem, character formulas, and asymptotic decay of matrix coefficients and temperedness). We hope this mix of topics appeals to nonspecialists in representation theory by illustrating (without an interminable prolegom ena) how representation theory can offer new perspectives on familiar topics and by offering some insight into some important themes in representation theory itself. Especially, we hope this book popularizes Harish-Chandra's restriction formula, which, besides being basic to his work, is simply a beautiful example of Fourier analysis on Euclidean space. We also hope representation theorists will enjoy seeing examples of how their subject can be used and will be stimulated by some of the viewpoints offered on representation-theoretic issues. 276 pp. Englisch.
