Taschenbuch. Condizione: Neu. Neuware - The Athens Conference on Applied Probability and Time Series in 1995 brought together researchers from across the world. The published papers appear in two volumes. Volume II presents papers on time series analysis, many of which were contributed to a meeting in March 1995 partly in honour of E.J. Hannan. The initial paper by P.M. Robinson discusses Ted Hannan's researches and their influence on current work in time series analysis. Other papers discuss methods for finite parameter Gaussian models, time series with infinite variance or stable marginal distribution, frequency domain methods, long range dependent processes, nonstationary processes, and nonlinear time series. The methods presented can be applied in a number of fields such as statistics, applied mathematics, engineering, economics and ecology. The papers include many of the topics of current interest in time series analysis and will be of interest to a wide range of researchers.

Buch. Condizione: Neu. Neuware - Parsing with Principles and Classes of Information presents a parser based on current principle-based linguistic theories for English. It argues that differences in the kind of information being computed, whether lexical, structural or syntactic, play a crucial role in the mapping from grammatical theory to parsing algorithms. The direct encoding of homogeneous classes of information has computational and cognitive advantages, which are discussed in detail. Phrase structure is built by using a fast algorithm and compact reference tables. A quantified comparison of different compilation methods shows that lexical and structural information are most compactly represented by separate tables. This finding is reconciled to evidence on the resolution of lexical ambiguity, as an approach to the modularization of information. The same design is applied to the efficient computation of long- distance dependencies. Incremental parsing using bottom-up tabular algorithms is discussed in detail. Finally, locality restrictions are calculated by a parametric algorithm. Students of linguistics, parsing and psycholinguistics will find this book a useful resource on issues related to the implementation of current linguistic theories, using computational and cognitive plausible algorithms.

Buch. Condizione: Neu. Neuware - This book was inspired by a gatheringofscientists in Los Angeles in 1994 under the auspices of the UCLA Clinical Nutrition Research Unit which is funded by the National Cancer Institute to promote new research into nutrition and cancer prevention. This unit supports research integrating basic and metabolic/clinical investigations which examine observations from epidemiologic studies and their application to the prevention ofcommon forms ofcancer through nutritional intervention. There is a great deal ofinformation from epidemiologic, experimental and metabolic studies implicating elements ofthe diet as important in the development and progression of common forms ofcancer including breast cancer, colon cancer, prostate cancer, and uterine cancer. When these forms ofcancerareexaminedcarefully, it isclearthat they share anumber ofcommon etiologic factors related to dietary fat, lipids, and hormones. A human cancer is usually discovered at a point where it has formed a detectable mass. For many forms of cancer, this may require 10 to 15 years from the time when the cancer is first initiated. Nutritional efforts at prevention may delay the progression ofcancer to a detectable mass resulting in reduced incidence and may retard the clinical progression and metastatic spread ofcancer after its primary treatment.

Buch. Condizione: Neu. Neuware - This book introduces the ten nation region of Southeast Asia: The main themes of the book are diversity, differential development and changing socio-economic and political setting affecting these characteristics in the 1990s. The nations of Southeast Asia have different languages, three dominant religions - Buddhism, Islam and Christianity, varied levels of economic development that range from bare agricultural subsistence to highly urbanized and highly developed. The historically based core areas of these countries have evolved on their own. Moreover, the effects of Indian, Chinese, Islamic, and Western cultures have been experienced differently in different nations at different times in their histories. This book is intended to be understood by all those who want an initial introduction to Southeast Asia. As many aspects of the book are the result of an in-depth research, carried out by the contributing authors, it is also a valuable reference. The contributing authors have portrayedthe basic spatial aspects of the region as well as their relevance in the 1990s based in novel ways and through original interpretations. All fIrst and some second authors of chapters are professors. All but one have Ph. Os. Most contributing authors are geographers but with different sub-specialties: P. P.

Buch. Condizione: Neu. Neuware - This volume contains the proceedings of the IFIP WG 6. 1 International Workshop on Testing of Communicating Systems (lWTCS'96), held in Darmstadt, Germany, on September 9 through II, 1996, continuing the IFIP WG 6. 1 series of International Workshops on Protocol Test Systems (IWPTS). In this series of working conferences, held annually since 1988, many valuable contributions have been presented with an emphasis both on the OSI conformance testing methodology and framework as well as the standardization effort on formal methods in conformance testing. While there are stilI open issues and divergencies between theory and practice in these fields, the scope of the series started expanding to related fields of growing practical relevance, for example to testing with regard to the B-ISDN protocol reference model, in particular ATM, the ODP reference model, and the Internet protocol suite, as well as to interoperability testing and performance testing. To reflect the extended scope, the program committee agreed on a new name for this series of working conferences, to be applied the first time to the 1996 conference. However, in order to emphasize the tradition of IWPTS, the numbering of this series was continued, such that IWTCS'96 is counted as the 9th International Workshop on Testing of Communicating Systems. As in the years before, the workshop aims at bringing together researchers and practi tioners, furthering the exchange of views, and correlating the work of both sides.

Buch. Condizione: Neu. Neuware - Food production remains the highest agricultural priority, subject to the constraint that it be done in harmony with nature, or at least with minimum environmental pollution. The amount of fertilizer applied can be controlled using modern application techniques, including soil and crop management, guaranteeing higher economic profit and lower environmental cost. It is in such a context that the present book addresses the efficient and rational use of mineral and organic fertilizers while preserving environmental quality. The book discusses the impact on surface and groundwaters, soils and crops, and experience of nitrate leaching, denitrification, ammonia volatilization, heavy metal pollution, agricultural and urban waste management, and international and national legislation. Audience: Agronomists, environmentalists, soil and food chemists, ecologists, policy makers, and managers in the fertilizer industry concerned with the trend of public opinion.

Buch. Condizione: Neu. Neuware - Historically, the field of hematopoietic growth factor research began with the work of Carnot and Deflandre-in 1906 they suggested that the rate of erythropoiesis is regulated by a humoral factor found in the blood, namely, erythropoietin. From this comparatively early start, accelerating progress has been made in erythropoietin research, which demon strates the general trends in this field of study. Erythropoietin was purified to homogeneity by 1977 (from enormous quantities of urine from aplastic anemia patients). Subsequently, the gene for erythropoietin has been cloned (1985), and massive quantities of this growth factor have been produced for clinical trials (late 1980s onward). Erythropoietin has become established as a pharmaceutical product of great value in the treatment of a number of diseases, most notably chronic renal failure. Once the ligand had been cloned, interest turned to the erythropoietin receptor, which was cloned in 1989. Since then, structure/ function studies have been performed on receptor mutants, cellular signaling events down stream from the occupied receptor have been identified, and the specific producer cell types and molecular stimuli for erythropoietin production have been thoroughly investigated, as has the regulation of erythropoietin gene transcription. This schedule of events since the 1970s typifies that seen for a number of hematopoietic growth factors. Along the way, the hematopoietic growth factors have been recognized as members of the cytokine family of signaling molecules that are important in a number of different physiological and patholog ical situations (see below).

Buch. Condizione: Neu. Neuware - TRACK 1: Innovative Applications in the Public Sector The integration of multimedia based applications and the information superhighway fundamentally concerns the creation of a communication technology to support the ac tivities of people. Communication is a profoundly social activity involving interactions among groups or individuals, common standards of exchange, and national infrastruc tures to support telecommunications activities. The contributions of the invited speakers and others in this track begin to explore the social dimension of communication within the context of integrated, information systems for the public sector. Interactions among businesses and households are described by Ralf Strauss through the development within a real community of a 'wired city' with information and electronic services provided by the latest telecommunications technologies. A more specific type of interaction between teacher and student forms the basis of education. John Tiffin demonstrates how virtual classrooms can be used to augment the educational process. Carl Loeffler presents yet another perspective on interaction through the integration of A-life and agent technologies to investigate the dynamics of complex behaviors within networked simulation environments. Common standards for communication in the form of electronic documents or CSCW (Computer Supported Cooperative Work), according to Roland Traunmiiller, provide en abling technologies for a paradigm shift in the management of organizations. As pointed out by William Olle, the impact of standardization work on the future of information technology depends critically upon the interoperability of software systems.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Heisenberg group comes from quantum mechanics and is the simplest non-commutative Lie group. While it belongs to the class of simply connected nilpotent Lie groups, it turns out that its special structure yields many results which (up to now) have not carried over to this larger class. This book is a survey of probabilistic results on the Heisenberg group. The emphasis lies on limit theorems and their relation to Brownian motion. Besides classical probability tools, non-commutative Fourier analysis and functional analysis (operator semigroups) comes in. The book is intended for probabilists and analysts interested in Lie groups, but given the many applications of the Heisenberg group, it will also be useful for theoretical phycisists specialized in quantum mechanics and for engineers. 156 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -When the destination sign on Scrooge's train reads 'HEAT DEATH' instead of 'HEATHROW,' when his dead partner Marley's face appears inexplicably as a talking head in a department store tv, and when the street lights outside his luxurious London flat begin acting strangely, it's a sign of a bad night to come. Like his famous ancestor, the modern Scrooge--who hews tightly to the credo 'it Is enough for a man to understand his own business and look to his own advantage'--is about to be visited by ghosts. But it's not his hard heart that needs opening this time; it's his closed mind. The wisdom these ghosts bring is not love and charity but Science. Physicist Robert Gilmore, author of the popular Alice in Quantumland, here presents a delightful takeoff on Charles Dickens' A Christmas Carol, where the three visitations represent Science Past (the Spirits of Energy and Entropy, who explain the laws of thermodynamics, equilibrium and that troublesome HEAT DEATH sign), Science Present (the Spirit of Time, who tells him of inconstancy, of change and also of creation), and Science Future (the surreal world of quantum uncertainty, where it is the observer or measurement that creates a unique reality). For everyone who wants a playful, painless yet surprisingly sophisticated introduction to the ideas of modern physics, this is a brilliant tour de force and a charming read. 268 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For several years now I have been teaching courses in computer algebra at the Universitat Linz, the University of Delaware, and the Universidad de Alcala de Henares. In the summers of 1990 and 1992 I have organized and taught summer schools in computer algebra at the Universitat Linz. Gradually a set of course notes has emerged from these activities. People have asked me for copies of the course notes, and different versions of them have been circulating for a few years. Finally I decided that I should really take the time to write the material up in a coherent way and make a book out of it. Here, now, is the result of this work. Over the years many students have been helpful in improving the quality of the notes, and also several colleagues at Linz and elsewhere have contributed to it. I want to thank them all for their effort, in particular I want to thank B. Buchberger, who taught me the theory of Grabner bases nearly two decades ago, B. F. Caviness and B. D. Saunders, who first stimulated my interest in various problems in computer algebra, G. E. Collins, who showed me how to compute in algebraic domains, and J. R. Sendra, with whom I started to apply computer algebra methods to problems in algebraic geometry. Several colleagues have suggested improvements in earlier versions of this book. However, I want to make it clear that I am responsible for all remaining mistakes. 288 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Disciplines, including Human-Computer Interaction (HCI), consist of knowledge supporting practices which solve general problems (Long & Dowell, 1989). A disci pline thus requires knowledge to be acquired which can be applied by practitioners to solve problems within the scope of the discipline. In the case of HCI, such knowledge is being acquired through research and, less formally, through the description of successful system development practice. Some have argued that knowledge is further embodied in the artefacts. HCI knowledge is applied to solve user interface design problems. Such applica tion is facilitated if the knowledge is expressed in a conception which makes explicit the design problems of practitioners. A conception has been proposed by Dowell & Long (1989). The conception provides a framework within which to reason about the implications of designs for system performance. The framework is concordant with the trend towards design, discernible in recent HCI research. It is further compatible with notions of top-down design, fundamental to software engineering practice. 2 Teaching and the HeI Research and Development Gap 2.1 An Assessment of Current HCI Education Teaching is one means by which practitioners learn to specify discipline problems. It is also a means by which they acquire knowledge to enable the problems to be solved. 416 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -People must have watched the skies from time immemorial. Human beings have always shown intellectual curiosity in abundance, and before the invention of modern distractions people had more time-and more mental energy-to devote to stargazing than we have. Megaliths, Chinese oracle bones, Babylonian clay tablets, and Mayan glyphs all yield evi dence of early peoples' interest in the skies. To understand early astronomy we need to be familiar with various phenomena that could-and still can-be seen in the sky. For instance, it seems that some early people were interested in the points on the horizon where the moon rises or sets and marked the directions of these points with megaliths. These directions go through a complicated cycle-much more complicated than the cycle of the phases of the moon from new to full and back to new, and more complicated than the cycle of the rising and setting directions of the sun. Other peoples were interested in the irregular motions of the planets and in the way in which the times of rising of the various stars varied through the year, so we need to know about these phenomena, i. e. , about retrogression and about heliacal rising, to usc the technical terms. The book opens with an explanation of these matters. Early astronomers did more than just gaze in awe at the heavenly bodies; they tried to understand the complex details of their movements.
