Nevertheless, there is a grain of truth in the 3 'prejudice': E (three-dimensional Euclidean space) is special in a particular way pleasantly familiar to us - in it we (also we mathematicians!) feel particularly 'confident' and move with a sense of greater 'safety' than in non-Euclidean spaces. For this reason perhaps, Riemann space M stands out among the multitude of 'interesting geometries'. For it is: 1. Locally Euclidean, i. e. , M is a differentiable manifold whose tangent spaces TxM are equipped with Euclidean metric Uxi 2. Every submanifold M of Euclidean space E is equipped with Riemann natural metric (inherited from the metric of E) and it is well known how often such submanifolds are used in mechanics (e. g. , the spherical pendulum).

Buch. Condizione: Neu. Neuware - Motion-based recognition deals with the recognition of an object and/or its motion, based on motion in a series of images. In this approach, a sequence containing a large number of frames is used to extract motion information. The advantage is that a longer sequence leads to recognition of higher level motions, like walking or running, which consist of a complex and coordinated series of events. Unlike much previous research in motion, this approach does not require explicit reconstruction of shape from the images prior to recognition. This book provides the state-of-the-art in this rapidly developing discipline. It consists of a collection of invited chapters by leading researchers in the world covering various aspects of motion-based recognition including lipreading, gesture recognition, facial expression recognition, gait analysis, cyclic motion detection, and activity recognition. Audience: This volume will be of interest to researchers and post- graduate students whose work involves computer vision, robotics and image processing.

Buch. Condizione: Neu. Neuware - This is the first publication of the 170 letters written by the Abbé Dominique Chaix to Dr. Dominique Villars between 1772 and 1799, when they were collaborating on the publication of the first flora for the old province of Dauphiné. The letters reveal the uncertainties of plant classification in the late 18th century, but, more generally, the penetration of the Enlightenment into a remote, alpine region of France. Both botanists were of recent peasant origin, invading, albeit deferentially, an intellectual field, traditionally the monopoly of their social betters. The letters also document the enthusiasms, anxieties, and perils of rural clerical life during the French Revolution, and give occasional evidence about the deforestation of the mountains.

Buch. Condizione: Neu. Neuware - The past two years have produced some of the most exciting results in the history of astronomy: the indirect detection of planets beyond our solar system. The study of the characteristics and physical nature of exo-planets requires an infrared interferometer in space. Such observatory would directly detect the thermal emission from exo-planets and would allow us to see signatures of molecules, e.g. water, ozone and carbon dioxide, in their atmospheres. The presence of such molecules would be strong evidence for exo-life. In addition, this kind of instrument would help to clarify important questions concerning the birth and death of stars and extragalactic astronomy. In Toledo, scientists and engineers from both sides of the Atlantic met for the first time to discuss the technological challenges of an infrared space interferometer and its scientific capabilities, particularly those related to exo-planetary systems and Earth-like planets.

Buch. Condizione: Neu. Neuware - Developing algorithms for multi-dimensional Fourier transforms, this book presents results that yield highly efficient code on a variety of vector and parallel computers. By emphasising the unified basis for the many approaches to both one-dimensional and multidimensional Fourier transforms, this book not only clarifies the fundamental similarities, but also shows how to exploit the differences in optimising implementations. It will thus be of great interest not only to applied mathematicians and computer scientists, but also to seismologists, high-energy physicists, crystallographers, and electrical engineers working on signal and image processing.

Buch. Condizione: Neu. Neuware - As our modem society is so obviously influenced by technology, there is a growing awareness of its importance for education. The interest for including technology as a part of general education curricula is increasing. In many countries technology is an element in the curriculum either as a topic, a project, part of a Science-Technology-Society (STS) programme, part of science education, or as a separate subject. In order to clarify what technology is, there is a need for international discussions in which philosophers, engineers, scientists and educational ists are involved. One of the few conferences with such a broad representation was the second Jerusalem International Science and Technology Education Conference (JISTEC) that was held in Jerusalem, January 8-11, 1996, a conference that can truly be seen as a milestone in the international history of technology education. More than 1,000 technology educators from more than 80 countries of the world and ministers of education from 28 coun tries came together to discuss current issues in technology education during JlSTEC. To cite from Dr. Michael Dyrenfurth's personal overview of the conference in the Journal of Industrial Teacher Education (vol. 33, no. 2, Winter 1996, pp. 83-85): 'Simply put, this conference represented the most stellar international collection of technology education advocates the world has ever seen in one place'.

Buch. Condizione: Neu. Neuware - This book, written by leading authors in the field, is the first to deal with all aspects of cytokine antibodies, from test methodology and standardization to biological consequences and functions. It encompasses antibodies induced by cytokines used therapeutically and antiviral antibodies. To understand the biology, the effects of cytokine antibodies in experimental animal models and patients are also discussed. The book is intended for researchers of cytokine biology, pharmaceutical companies developing cytokines and cytokine antibodies as therapies, and clinicians interested in modulating the immune system as therapy.

Buch. Condizione: Neu. Neuware - As our title suggests, there are two aspects in the subject of this book. The first is the mathematical investigation of the dynamics of infinite systems of in teracting particles and the description of the time evolution of their states. The second is the rigorous derivation of kinetic equations starting from the results of the aforementioned investigation. As is well known, statistical mechanics started in the last century with some papers written by Maxwell and Boltzmann. Although some of their statements seemed statistically obvious, we must prove that they do not contradict what me chanics predicts. In some cases, in particular for equilibrium states, it turns out that mechanics easily provides the required justification. However things are not so easy, if we take a step forward and consider a gas is not in equilibrium, as is, e.g., the case for air around a flying vehicle. Questions of this kind have been asked since the dawn of the kinetic theory of gases, especially when certain results appeared to lead to paradoxical conclu sions. Today this matter is rather well understood and a rigorous kinetic theory is emerging. The importance of these developments stems not only from the need of providing a careful foundation of such a basic physical theory, but also to exhibit a prototype of a mathematical construct central to the theory of non-equilibrium phenomena of macroscopic size.

Buch. Condizione: Neu. Neuware - In the conflict between logging as a material resource and preservation the forests are becoming depleted throughout the world and this depletion is aggravated by the effects of air pollution. The concept of utilization is thus now being expanded to include vital societal values. These issues are nowhere more acute than in Central and Eastern Europe, where obsolete, poorly maintained industrial plant is common. Air pollutant levels are so high that one area has been called the Black Triangle. Timber is required in this region as a building material and logging for fuelwood is practised, giving rise to a complex linkage between industry, energy supply, deforestation, agriculture, value-added forestry products and economic development. This book presents current information on national and regional issues relating to environmental threats to forest land, focusing on: ecology, environment and science; forest ownership and management; forest product utilization; government and public agency roles. The recommendations, action items and the human network needed for regional-level implementation are detailed in `situation', `position' and `state of the art' papers. The final objective is to develop a plan of action to help abate the negative impacts while sustaining or expanding the forests, the economy and the energy sufficiency of the region.

Buch. Condizione: Neu. Neuware - The Society of Environmental Geochemistry and Health (SEGH) Second International Conference on Arsenic Exposure and Health Effects was held June 12-14, 1995 in San Diego, California. The conference was at tended by 152 people who heard 41 presentations on all aspects of arsenic research. The speakers represented 14 countries. Approximately 40 of the participants and speakers were from countries other than the US. The participants represented government, academia, industry and the interested public. The sponsorship ofthe conference is a good indicationofthe wide spread interest in the subject and the meeting. The sponsors, in addition to SEGH, were the US Environmental Protection Agency (US EPA), the Agency for Toxic Substances and Disease Registry (ATSDR), the Atlantic Richfield Company (ARCO), the Electric Power Research Institute (EPRI), the American Water Works Association Research Foundation (AWWARF), Kennecott Corporation, the American Smelting and Refining Company (ASARCO), and the International Council on Metals in the Environment (ICME). The funding was split approximately equally between industry (including industrial organizations such as EPRI) and government. In addition to the many fine presentations, the meeting provided a forum for scientists from different countries to compare experiences and share information. It also provided a forum for the discussion of both scientific and policy issues between representatives of various governmental bodies (at the local, state, and federal level) and representatives of various indus trial organizations. These discussions occurred both in the formal meetings and informal settings during the meeting.

Buch. Condizione: Neu. Neuware - Symbolic Analysis in Analog Integrated Circuit Design provides an introduction to computer-aided circuit analysis and presents systematic methods for solving linear (i.e. small-signal) and nonlinear circuit problems, which are illustrated by concrete examples. Computer-aided symbolic circuit analysis is useful in analog integrated circuit design. Analytic expressions for the network transfer functions contain information that is not provided by a numerical simulation result. However, these expressions are generally extremely long and difficult to interpret; therefore, it is necessary to be able to approximate them guided by the magnitude of the individual circuit parameters. Engineering has been described as `the art of making approximations'. The inclusion of symbolic analysis in analog circuit design reduces the implied risk of ambiguity during the approximation process. A systematic method based on the nullor concept is used to obtain the basic feedback transistor amplifier configurations. Approximate expressions for the locations of poles and zeros for linear networks are obtained using the extended pole-splitting technique. An unusual feature in Symbolic Analysis in Analog Integrated Circuit Design is the consistent use of the transadmittance element with finite (linear or nonlinear) or infinite (i.e. nullor) gain as the only requisite circuit element. The describing function method is used to obtain approximate symbolic expressions for the harmonic distortion generated by a soft or hard transconductance nonlinearity embedded in an arbitrary linear network. The design and implementation of a program (i.e. CASCA) for symbolic analysis of time-continuous networks is described. The algorithms can also be used to solve other linear problems, e.g. the analysis of time-discrete switched-capacitor networks. Symbolic Analysis in Analog Integrated Circuit Design serves as an excellent resource for students and researchers as well as for industry designers who want to familiarize themselves with circuit analysis. This book may also be used for advanced courses on the subject.

Buch. Condizione: Neu. Neuware - The impact of climate on human activities and the effect of humans on cli mate are two of the most important areas of inquiry in climatology. These interactions conducted through physical, chemical and biological process es were described as early as Roman and Greek times. Marcus Vitruvius (75-25 B. C. ), a famous Roman engineer and architect, made the following observation about the climatic conditions necessary for founding a city: Land ideal for the health is slightly elevated and there should be neither fog nor frost. The direction of the slope and the distance to the swamps, lakes, and beaches must also be considered. The prevailing wind directions, observed by a wind tower at the center of the city, like Horologium at Athens, should be taken into consideration in city planning. The main and narrow streets should be placed in the middle angle of the two prevailing wind directions. Then the location of the Pantheons and squares should be decided. The influence of humans on climate was a major subject for discussion in the 19th century, inspired in part, by the rapid industrial growth and expanding deforestation of the time. D. L. Howard wrote brilliant pieces on the climate of London in the 1830s, while G . P. Marsh discussed the effects of forests on precipitation in the U. S . A. in the second half of the 19th century.

Buch. Condizione: Neu. Neuware - This book has been written to ensure that it will be of benefit to industrial analysts. Most chapters explain some of the relevant theory as well as give some historical references to place the technique in its proper context. In addition the book should appeal to academic scientists who require a good source of applications and a good set of references. Since lipids have many uses the appeal of the book will extend from the food industry to the pharmaceutical industry. R.

Buch. Condizione: Neu. Neuware - This monograph series is intended to provide medical information scien tists, health care administrators, physicians, nurses, other health care pro viders, and computer science professionals with successful examples and experiences of computer applications in health care settings. Through these computer applications, we attempt to show what is effective and efficient, and hope to provide guidance on the acquisition or design of medical information systems so that costly mistakes can be avoided. Health care provider organizations such as hospitals and clinics are experiencing large demands for clinical information because of a transition from a 'fee-for-service' to a 'capitation-based' health care economy. This transition changes the way health care services are being paid for. Previ ously, nearly all health care services were paid for by insurance companies after the services were performed. Today, many procedures need to be pre approved and many charges for clinical services must be justified to the insurance plans. Ultimately, in a totally capitated system, the more patient care services are provided per patient, the less profitable the health care provider organization will be. Clearly, the financial risks have shifted from the insurance carriers to the health care provider organizations. For hospitals and clinics to assess these financial risks, management needs to know what services are to be provided and how to reduce them without impacting the quality of care. The balancing act of reducing costs but maintaining health care quality and patient satisfaction requires accurate information about the clinical services.

Buch. Condizione: Neu. Neuware - Drying is traditionally defined as that unit operation which converts a liquid, solid or semi-solid feed material into a solid product of significantly lower moisture content. In most, although not all, cases it involves the application of thermal energy, which causes water to evaporate into the vapour phase. In practice, this definition encompasses a number of technologies which differ markedly in, for example, the manner in which energy is supplied to the foodstuff and in which product is transported through the dryer. Depending on the dryer type, the residence time may vary from a few seconds to several hours. Dryers designed to handle liquid feedstocks are naturally quite different from those intended to process moist solids. Even within these two broad categories, however, many distinct varieties of dryer have evolved to meet specific process ing needs. The dryer is frequently the last processing stage in the manufacture of a dehydrated food product. As such, it may not only bring about the desired reduction in moisture content but may also have a significant effect on a number of other properties, such as flavour, colour, texture, viability, and nutrient retention, for example. These properties, which are generally considered to affect the perceived quality of the end product, are often influenced by the temperature- moisture content-time profiles experienced by the foodstuff as it moves through the dryer. The underlying chemistry and physics are highly complex and, broadly speaking, only poorly understood.

Buch. Condizione: Neu. Neuware - Switched-Current Design and Implementation of Oversampling A/D Converters discusses the switched-current (SI) technique and its application in oversampling A/D converters design. The SI technique is an analog sampled-data technique that fully exploits the digital CMOS process. Compared with the traditional switched-capacitor (SC) technique, the SI technique has both pros and cons that are highlighted in the book. With the consideration of similarity and difference of SI and SC techniques, oversampling A/D converter architectures are tailored and optimized for SI design and implementation in the book. Switched-Current Design and Implementation of Oversampling A/D Converters emphasizes the practical aspects of SI circuits without tedious mathematical derivations, and is full of circuit design and implementation examples. There are more than 10 different chips included in the book, demonstrating the high-speed (over 100 MHz) and ultra-low-voltage (1.2 V) operation of SI circuits and systems in standard digital CMOS processes. Therefore, the book is of special value as a practical guide for designing SI circuits and SI oversampling A/D converters. Switched-Current Design and Implementation of Oversampling A/D Converters serves as an excellent reference for analog designers, especially A/D converter designers, and is of interest to digital designers for real-time signal processing who need A/D interfaces. The book may also be used as a text for advanced courses on the subject.

Buch. Condizione: Neu. Neuware - Food security is defined as the ability of countries, regions, or households to meet their required levels of food consumption at all times. Food security is an important component of human welfare, and it can act as an indicator of a region's development. This book addresses the roles of trade, policy development, and economic cooperation in creating sustainable food security in the West African region. The largely micro-level analysis is conducted on empirical data from the household where decisions on production and consumption take place. Food security is discussed in terms of its component parts, namely: availability of food (production and trade), its accessibility (incomes and poverty status), and its utilisation (health and nutrition).

Buch. Condizione: Neu. Neuware - EMU - A Swedish Perspective provides a comprehensive and up-to-date survey of the EMU project. The main advantages and disadvantages of a single currency are evaluated. A key feature of the analysis is the attempt to integrate economic and political aspects. The book is a revised version of the report by the Swedish Government Commission on the EMU. Although the analysis focuses on the consequences for Sweden of joining versus not joining the monetary union, it is highly relevant for the discussion in all EU countries. The book provides an in-depth analysis of how the demands on economic policy will be affected by the monetary union. Various chapters discuss monetary policy and inflation, fiscal policy, unemployment and labour markets, the transition to monetary union, and the exchange-rate arrangements between participants and non-participants. Other chapters analyse the importance of the EMU for European political integration, democratic aspects, and how membership in the monetary union will affect the possibilities for an individual member state to exert influence within the EU. EMU - A Swedish Perspective should be of interest to professional economists and political scientists, students, and all others who want to form an opinion about the monetary union on the basis of a balanced assessment of the consequences.
