Buch. Condizione: Neu. Neuware - Major international, interdisciplinary research programmes are now underway to increase our understanding of how the Earth System operates and how it is changing through the effects of human activities. Although understanding and predictive capacity are still limited, scientists already agree that significant global changes must be expected in the next 50 years that will affect the capacity of the Earth to sustain life. Governments, business and industry have, therefore, come to recognize that scientific knowledge about the changing global environment - as yet incomplete but rapidly evolving - is becoming indispensable for wise long-term policy making, the goal being to design preventive, adaptive and remedial measures. Thus global change science and policy making are engaged in a process of forming a new partnership that is taking shape as further insights evolve. Effective continuous interactions between the partners requires mutual understanding: decision-makers need to understand the unique potential but also the limitations of the results of scientific research in progress while scientists must take into account the priorities and constraints of policy-makers in designing and implementing policies that will promote long-term sustainability of life on this planet. This book contributes in a unique manner to this mutual understanding: It gives an overview of the ongoing relevant research focusing on the two major international programmes, the International Geosphere-Biosphere Programme and the World Climate Research Programme. These are described in terms understandable to the interested lay reader. The results of the latest review of the Intergovernmental Panel on Climate Change (IPCC) are included. This is followed by an analysis of the response process that is in progress with respect to governments - singly and multilaterally - by business and industry and by public interest groups. This process is leading to interactive structures, assessment procedures and legislation, nationally and internationally. Business and industry are changing from mere watchfulness to recognition of new opportunities for products and processes. Six interviews with prominent figures from business and government circles in the Netherlands provide a vivid illustration of the questions at issue. The appendices provide overviews of methods for incorporating the results of global change science into policy-making and development of long lasting projects. Adaptation to climate change serves as an example. Thus, for the first time, one book describes both ongoing research work in global change and the response processes that the research results are evoking. It is of interest to all stake-holders in the scientific community as well as to decision-makers in industry, business and government.

Buch. Condizione: Neu. Neuware - Northern Ireland's problems are rooted in physical and historical geography: small resource base, peripheral location, violent conquest, repression and ruthless emargination of the native population by the Protestant settlers. At the time of partition, many areas already had a Catholic majority, and the Catholic population is increasing faster, thereby undermining the Protestant position. Britain gains no advantage by keeping Northern Ireland. Nevertheless, this solution is not going to be cheap, not merely because of opposition by Protestant loyalists, but also because of the economic weakness of both Irelands. Unlike other books on the subject, this one goes to the heart of the matter: Britain would be serving her own interest by easing reunification of Ireland, albeit gradually and cautiously. In this perspective, the conclusion is that history is inexorably moving beyond Northern Ireland. Audience: European Community administrators and planners,diplomats, politicians, students in Political Science, Economics, History and Geography.

Buch. Condizione: Neu. Neuware - Locality in WH Quantification argues that Logical Form, the level that mediates between syntax and semantics, is derived from S-structure by local movement. The primary data for the claim of locality at LF is drawn from Hindi but English data is used in discussing the semantics of questions and relative clauses. The book takes a cross-linguistic perspective showing how the Hindi and English facts can be brought to bear on the theory of universal grammar. There are several phenomena generally thought to involve long-distance dependencies at LF, such as scope marking, long-distance list answers and correlatives. In this book they are handled by explicating novel types of local relationships that interrogative and relative clauses can enter. A more articulated semantics is shown leading to a simpler syntax. Among other issues addressed is the switch from uniqueness/maximality effects in single wh constructions to list readings in multiple wh constructions. These effects are captured by adapting the treatment of wh expressions as quantifying over functions to the cases of multiple wh questions and correlatives. List readings due to functional dependencies are systematically distinguished from those that are based on plurality.

Buch. Condizione: Neu. Neuware - Since January 1990, when the first edition ofthis first-of-a-kind book appeared, there has been much experimental and theoretical progress in the multi disciplinary subject of tribology and mechanics of magnetic storage devices. The subject has matured into a rigorous discipline, and many university tribology and mechanics courses now routinely contain material on magnetic storage devices. The major growth in the subject has been on the micro- and nanoscale aspects of tribology and mechanics. Today, most large magnetic storage industries use atomic force microscopes to image the magnetic storage components. Many companies use variations of AFMs such as friction force microscopes (FFMs) for frictional studies. These instruments have also been used for studying scratch, wear, and indentation. These studies are valuable in the fundamental understanding of interfacial phenomena. In the second edition, I have added a new chapter, Chapter 11, on micro and nanoscale aspects of tribology and mechanics of magnetic storage compo nents. This chapter presents the state of the art of the micro/nanotribology and micro/nanomechanics of magnetic storage components. In addition, typographical errors in Chapters 1 to 10 and the appendixes have been corrected. These additions update this book and make it more valuable to researchers of the subject. I am grateful to many colleagues and particularly to my students, whose work is reported in Chapter 11. I thank my wife, Sudha, who has been forbearing during the progress of the research reported in this chapter.

Buch. Condizione: Neu. Neuware - The aim of this book is to present readers with state-of-the-art options which allow pupils as well as teachers to cope with the social impacts and implications of information technology and the rapid technological developments of the past 25 years. The book explores the following key areas: the adaption of curricula to the social needs of society; the influences of multimedia on social interaction; morals, values and ethics in the information technology curriculum; social and pedagogical variables which promote information technology use; and social implications of distance learning through the medium of information technology. This volume contains the selected proceedings of the TC3/TC9 International Working Conference of the Impact of Information technology, sponsored by the International Federation for Information Processing and held in Israel, March, 1996.

Buch. Condizione: Neu. Neuware - In recent years there has been rapid progress in the development of signal processing in general, and more specifically in the application of signal processing and pattern analysis to biological signals. Techniques, such as parametric and nonparametric spectral estimation, higher order spectral estimation, time-frequency methods, wavelet transform, and identifi cation of nonlinear systems using chaos theory, have been successfully used to elucidate basic mechanisms of physiological and mental processes. Similarly, biological signals recorded during daily medical practice for clinical diagnostic procedures, such as electroen cephalograms (EEG), evoked potentials (EP), electromyograms (EMG) and electrocardio grams (ECG), have greatly benefitted from advances in signal processing. In order to update researchers, graduate students, and clinicians, on the latest developments in the field, an International Symposium on Processing and Pattern Analysis of Biological Signals was held at the Technion-Israel Institute of Technology, during March 1995. This book contains 27 papers delivered during the symposium. The book follows the five sessions of the symposium. The first section, Processing and Pattern Analysis of Normal and Pathological EEG, accounts for some of the latest developments in the area of EEG processing, namely: time varying parametric modeling; non-linear dynamic modeling of the EEG using chaos theory; Markov analysis; delay estimation using adaptive least-squares filtering; and applications to the analysis of epileptic EEG, EEG recorded from psychiatric patients, and sleep EEG.

Buch. Condizione: Neu. Neuware - The IFIP International Working Conference on Intelligent Networks '95 was held at the Technical University of Denmark (DTU) in Copenhagen. The conference was organised jointly by the Center for Tete-Information at DTU and Tele Danmark Research! during August 30-31 1995 and was hosted by the Center for Tete-Information. The conference was sponsored by IFIP TC6. The papers contained in this book are edited versions of the papers from the conference and some of the tutorial presentations that were arranged prior to the conference. The mixture of tutorial papers and conference papers gives a broad and yet thorough coverage of activities and central areas of development in the IN world at this point in time. Future developments, especially in the area of extended mobility support and multimedia capabilities, are also pre sented. BACKGROUND The theme of the conference was the two major trends in Intelligent Networks (IN) develop ment: - ITU and ETSI based IN standards, such as CS-1 and the upcoming CS-2 and - long term development as undertaken by, for example, the TINA consortium and the Euro pean RACE and ACTS programmes. The present IN technology based on capability sets is on its way into the networks, and opera tors are pushing for open platforms to be deployed in the networks in the near future in order to obtain greater freedom in selecting platforms for service provisioning.

Buch. Condizione: Neu. Neuware - Enterprise integration and enterprise engineering has become a focal point of discussions during the past few years with active contribution of many disciplines. The evolution from the concept of CAD/CAM, through CIM to the Integrated Enterprise is based on the assumption that the integrated enterprise can (and should) be engineered just as any complex system can.

This contributed volume has also been published as a special double issue of the Journal of Intelligent Information Systems (JIIS), Volume 6:2/3.

Buch. Condizione: Neu. Neuware - Nonsmooth energy functions govern phenomena which occur frequently in nature and in all areas of life. They constitute a fascinating subject in mathematics and permit the rational understanding of yet unsolved or partially solved questions in mechanics, engineering and economics. This is the first book to provide a complete and rigorous presentation of the quasidifferentiability approach to nonconvex, possibly nonsmooth, energy functions, of the derivation and study of the corresponding variational expressions in mechanics, engineering and economics, and of their numerical treatment. The new variational formulations derived are illustrated by many interesting numerical problems. The techniques presented will permit the reader to check any solution obtained by other heuristic techniques for nonconvex, nonsmooth energy problems. A civil, mechanical or aeronautical engineer can find in the book the only existing mathematically sound technique for the formulation and study of nonconvex, nonsmooth energy problems. Audience: The book will be of interest to pure and applied mathematicians, physicists, researchers in mechanics, civil, mechanical and aeronautical engineers, structural analysts and software developers. It is also suitable for graduate courses in nonlinear mechanics, nonsmooth analysis, applied optimization, control, calculus of variations and computational mechanics.

Buch. Condizione: Neu. Neuware - Theory and practice of tolerances are very important for designing and manufacturing engineering artifacts on a rational basis. Tolerance specifies a degree of 'discrepancy' between an idealized object and its physical realization. Such discrepancy inevitably comes into our product realization processes because of practical cost consideration or our inability to fully control manufacturing processes. Major product and production characteristics which are affected by tolerances are product quality and cost. For achieving high precision machines tight tolerance specification is necessary, but this will normally increase product cost. In order to optimally compromise the conflicting requirements of quality and cost, it is essential to take into account of the total product life cycle throughout product planning, design, manufacturing, maintenance and recycling. For example, in order to construct durable products under severe working conditions, low sensitivity of product functionality with respect to tolerances is required. In future, re-use of components or parts will become important, and tolerance synthesis with respect to this aspect will be an interesting future research topics.

Buch. Condizione: Neu. Neuware - One of the first priority areas among joint East/West research programs is the rational use of natural resources and sustainable development of regions. In the boreal zone of North America and Eurasia forests are economically very important and, at the same time highly vulnerable to disturbances. Because of its size and ecological functions the boreal forest zone and its most dynamic disturbance factor - fire - play an important role in ecosystem processes on global scale. Interest within the global change research community in Northern Eurasia (Fennoscandia, European Russia, Siberia, and the Far East of Russia) has grown dramatically in the last few years. It is a vast area about which very little is known. It is a region where temperature rise due to anthropogenic climate forcing is predicted to be the greatest, and where the consequent feedbacks to the atmosphere are potentially large. In addition, it is poised to undergo rapid economic development, which may lead to large and significant changes to its land cover. Much of this interest in Northern Eurasia, as in the high latitude regions in general, is centerd on its role in the global carbon cycle, which is likely to be significantly affected under global change. New research initiatives between Western and Eastern countries have been designed to address a series of phenomena, problems and management solutions.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Induced seismic events are of high scientific and economic significance. They are the result of human activities interacting with regional and local tectonics, changing the local crustal stress state by mining, extraction of rock masses, injection of fluids into the rock massif, and by changing the surface loading and pore pressure state near large reservoirs. Within Europe the study of induced seismic events has a long tradition and international scientific organizations have actively stimulated the co-operation in this field. During its General Assembly in September 1994, the European Seismological Society organized the symposium 'Induced Seismic Events'. The focus of this symposium was concentrated on induced events in central and eastern Europe, as well as in the former Soviet Union. The major contributions to the symposium, and also some Chinese, Canadian, and South African results are presented here. Case studies as well as data analyses and methodological studies are included. Seismologists and specialists working in the field of geohazard prevention will find much information in this volume that is pertinent to their work. 230 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The usage of data communications and computer networks are ever in creasing. It is one of the few technological areas which brings benefits to most of the countries and the peoples of the world. Without it many industries could not exist. It is the objective of this book to discuss data communications in a readable form that students and professionals all over the world can understand. As much as possible the text uses dia grams to illustrate key points. Most currently available data communications books take their view point from either a computer scientists top-down approach or from an electronic engineers bottom-up approach. This book takes a practical ap proach and supports it with a theoretical background to create a textbook which can be used by electronic engineers, computer engineers, computer scientists and industry professionals. It discusses most of the current and future key data communications technologies, including: - Data Communications Standards and Models; - Local Area Networks (Ethernet, Token Ring and FDDI); - Transmission Control ProtocollInternet Protocol (TCPIIP); - High-level Data Link Control (HDLC); - X.25 Packet-switching; - Asynchronous Communications (RS-232) and Modems; - Pulse Coded Modulation (PCM); - Integrated Digital Services Network (ISDN); - Asynchronous Transfer Mode (ATM); - Error Control; - X-Windows. The chapters are ordered in a possible structure for the presentation of the material and have not been sectioned into data communications areas. 384 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Much has already been written about the effects of the changes of the Cold War on conflict. The ongoing disengagement of East and West from bipolar Cold-War politics has resulted in an unstable international political situation which is characterized by regional conflicts. Most analyses now concentrate on the consequences for Europe and the former communist Central and East European states. This book, however, explores the effects for the Third World. The contributors provide major theoretical analyses of the causes of conflict in developing countries. Four main factors are distinguished: the processes of state-formation and nation-building; the rise or return of ethnicity and nationalism; socio-economic factors; and the armaments-conflict nexus. The volume also provides in-depth regional analyses, as well as policy perspectives on the issue of conflict and development. 376 pp. Englisch.

Producers have to decide today which amount of a good they will produce not knowing what demand will be tomorrow. Consumers have to decide what they spend for consumption today not knowing what prices will prevail tomorrow. Adopting the neo-classical point of view that economic agents are 'rational' in the sense that they behave in their own best interest given their expectations about future states of the ecomomy it is usually assumed that agents are Bayesian deci sion makers. But, as LUCAS points out, there remains an element of indeterminacy: Unfortunately, the general hypothesis that economic agents are Bayesian decision makers has, in many applications, lit tle empirical content: without some way of infering what an agent's subjective view of the future is, this hypothesis is of no help in understanding his behavior. Even psychotic behavior can be (and today, is) understood as 'rational', given a sufficiently abnormal view of relevant probabili ties. To practice economics, we need some way (short of psychoanalysis, one hopes) of understanding which decision problem agents are solving. (LucAs (1977, p. 15)) 2 CHAPTER 1.

This item is printed on demand - it takes 3-4 days longer - Neuware -We investigate a two-person game of litigation and settlement with incomplete information on one side. So far, various theoretical attempts have been made to answer the question of why some people choose not to resolve their disputes and instead go to court and incur litigation costs, even if bargaining leaves room for both parties to fare better when avoiding the conflict. We can distinguish between games which focus on strategic elements like games with incomplete information (see, for example, P'ng (1983), Samuelson (1982) and Schweizer (1989' and decision-theoretic models neglecting strategic elements (see, for example, Landes (1971) and Gould (1973'. The single-person decision theory approach to litigation assumes litigants to have a subjective estimate of the likelihood that the plaintiff will win the action. Differing views on the probability of winning the court case help to explain the fraction of cases that actually go to trial. Among others, P'ng (1983) points out the shortcomings of the single-person decision theory approach which does not take into account, for example, the different fee systems in England and the U.S. and the differences in information conflicting parties may have. P'ng constructs a model of one-sided incomplete information where the settlement terms are given exogenously. Schweizer (1989), on the other hand, extends P'ng's model and allows for two-sided asymmetric information where the settlement terms are determined endogenously. 188 pp. Englisch.

As a matter of fact an important number of papers have been based on analytical calculations. More recently numerical simulations have been extensively used. for instance for large displacement analysis. for shape optimization or even -in linear analysis -for composite material understanding. But all these works lie on a choice of a finite element scheme which contains usually three kinds of approximations: 1. a plate or shell mndel including smnll parameters associated to the thickness, 2. an approximntion of the geometry (the medium sUrface of a shell and its boundary), 3. afinite element scheme in order to solve the mndel chosen. VI Obviously the conclusions that we can draw are very much depending on the quality of the three previous choices. For instance composite laminated plates with damage like a delamination is still an open problem even if interesting papers have already been published and based on numerical simulation using existing fmite element and even plate models. - In our opinion the understanding of plate modelling is still an area of interest. Furthermore the links between the various models have to be handled with care. The certainly best understood model is the Kirchhoff-Love model which was completely justified by P. O. Ciarlet and Ph. Destuynder in linear analysis using asymptotic method. But the conclusion is not so clear as far as large displacements are to be taken into account. 252 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -America's relationship with Japan recently passed its 140th anniversary. Although over those years, hundreds of books and thousands of articles have explored different issues or periods of the relationship, no book has analyzed the entire relationship from beginning to present. The void can perhaps be explained by the relationship's complexity and changes over time. Two great cycles of initial partnership and eventual rivalry have shaped American-Japanese relations, one geopolitical (1853-1945) and the other geoeconomic (1945-present). This book fills that void as it systematically untangles the interrelated perceptions, convergent and divergent national interests, and shifting power relations which have shaped American policies toward Japan within those two great cycles. More specifically, it highlights the personalities, national moods, domestic issues and political alignments, and other pressing international concerns within which Washington has attempted to define and assert its interests toward Japan. 446 pp. Englisch.

Because of increasing life expectancy dementia poses a major health and socio economic problem. Alzheimer's disease accounts for 70-90% of mental decline in the elderly. Degenerative non-Alzheimer's dementi as are responsi ble for 7-30%. These include a variety of disorders clinically characterised by progressive cognitive dysfunction often combined with focal neurological def icits, e.g. Parkinson-plus syndromes, Lewy body dementia, lobar and multisys tem atrophies, other neurodegenerative disorders, and prion diseases. Often it is difficult to distinguish these illnesses from Alzheimer's disease and vascu lar dementia. In spite of considerable progress in molecular genetics, biochemistry, and neuropathology, the classification and pathogenesis of non-Alzheimer's dementias are still debatable. Diagnosis is frequently made only at postmor tem. Because disease markers are not available for the majority of non Alzheimer's dementias, consensus criteria for the identification of such diseas es are warranted. These criteria could serve at a basis for early diagnosis and distinction from other dementing disorders. 300 pp. Englisch.

Modem air travel effectively circumvents existing quarantine regulations as infected individuals thereby can reach almost every geographic location while stiIl in the incubation phase of the disease. Hence, infections previously restricted to distinet regions due to their strict association with non-human reservoirs or vectors can suddenly surface in non-endemic areas where lacking experience and technical means make clinical and laboratory diagnosis difficult. Excellent examples for such situations are many vector- or rodent-borne viruses but also hepatitis viruses, the human immunodeficiency virus and, last but not least, filoviruses. The following articles are based on papers presented at an international symposium on 'Imported Virus Infections' heI d at the Max von Pettenkofer Institute, University ofMunich, Munich, Germany on March 31 to Aprill, 1995. They illustrate today's knowledge on the epidemiology, dynamics of spread, as weIl as the frequently limited possibilities of prevention and therapeutic treat ment of associated disease. Special emphasis was placed on filovirus infections which, as if to highlight the topics of the symposium, reappeared and spread in Zaire in the first half of 1995.
