Buch. Condición: Neu. Neuware - The papers in this book are organized as follows: insect-plant communities, host-plant selection, genetics and evolution, host-plant resistance and application of transgenic plants, and multitrophic interactions. Besides seven invited papers and a paper with concluding remarks, this volume also contains the short communications of all 115 oral presentations and posters. Included too, are the summaries of four European Science Foundation workshops held over the past two years, where European scientists discussed the state-of-the-art and the future of major topics in insect-plant interactions in order to develop better integrated research programs. The field of insect-plant interactions nowadays includes almost all of biology, as well as parts of chemistry and physics. It takes a central position in biology because insects are the most abundant animal group, half of them are herbivores and they dominate all terrestrial ecosystems. Knowledge of insect-plant interactions is thus fundamental to an understanding of the evolution of life on Earth. Two major topics of worldwide concern give this field an extra dimension. First, large amounts of food crops are still lost due to insect pests. With the increasing concern for environmental pollution and the subsequent plans to drastically reduce pesticides, integrated pest management and development of resistant crops become a major focus in agriculture. The importance of the study of insect-plant relationships is thus continuously augmented. Clearly, successful pest control demands sufficient fundamental knowledge of pest-host interactions. Second, such work can contribute towards stopping or even counterbalancing the threatening biodiversity crisis thanks to an understanding of how the interaction of insects and plants has influenced and still influences the diversification and speciation (evolution) of both groups. These problems should, of course, be approached at a multitrophic level.…

Buch. Condición: Neu. Neuware - Agroforestry reserach and development in Australia has been largely fragmented and many of the research results have never been published and are unknown. The purpose of this volume is to comprehensively review all of the research that has taken place in the field of agroforestry in Australia, including previously unpublished results, providing readers with the latest technical and economic information about using trees in agriculture for the control of salinity and erosion, for shelter and shade, and for the production of timber, fodder and minor forest products. The book provides information concerning planted trees within all of these categories and includes special review of the management of native vegetation on farms. These papers also examine research needs where appropriate. This book stems from the National Australian Conference on 'The Role of Trees in Sustainable Agriculture' which took place in Albury, Victoria, Australia in October, 1991. Each national review paper is based upon a summary of six or more state review research and development papers, prepared specifically for the national conference. The book thus provides readers with a comprehensive overview of agroforestry rsearch in Australia, which is introduced and summarised in the first chapter.…

Buch. Condición: Neu. Neuware - One of the most intriguing questions about the new computer technology that has appeared over the past few decades is whether we humans will ever be able to make computers learn. As is painfully obvious to even the most casual computer user, most current computers do not. Yet if we could devise learning techniques that enable computers to routinely improve their performance through experience, the impact would be enormous. The result would be an explosion of new computer applications that would suddenly become economically feasible (e. g. , personalized computer assistants that automatically tune themselves to the needs of individual users), and a dramatic improvement in the quality of current computer applications (e. g. , imagine an airline scheduling program that improves its scheduling method based on analyzing past delays). And while the potential economic impact ofsuccessful learning methods is sufficient reason to invest in research into machine learning, there is a second significant reason: studying machine learning helps us understand our own human learning abilities and disabilities, leading to the possibility of improved methods in education. While many open questions remain aboutthe methods by which machines and humans might learn, significant progress has been made.…

Buch. Condición: Neu. Neuware - Computer-Aided Verification is a collection of papers that begins with a general survey of hardware verification methods. Ms. Gupta starts with the issue of verification itself and develops a taxonomy of verification methodologies, focusing especially upon recent advances. Although her emphasis is hardware verification, most of what she reports applies to software verification as well. Graphical presentation is coming to be a de facto requirement for a `friendly' user interface. The second paper presents a generic format for graphical presentations of coordinating systems represented by automata. The last two papers as a pair, present a variety of generic techniques for reducing the computational cost of computer-aided verification based upon explicit computational memory: the first of the two gives a time-space trade-off, while the second gives a technique which trades space for a (sometimes predictable) probability of error. Computer-Aided Verification is an edited volume of original research. This research work has also been published as a special issue of the journal Formal Methods in System Design, 1:2-3.…

Buch. Condición: Neu. Neuware - William Darity, Jr. In 1984 the Kluwer series in Modern Economic Thought, under the editorial direction of Warren Samuels, brought out a book under my editorship entitled Labor Economics: Modern Views. It consisted of a series of essays and commentaries that sought, in a critical fashion, to assess the state of the art in the field of labor economics with respect to several themes. These included methodology versus practice, the analysis of discrimination by gender and race, the phenomenon of persistent racial differences in un employment exposure, occupational safety and health regulation, dual versus segmented labor markets, and the remnants of the Phillips curve trade-off between unemployment and inflation. Nearly a decade later I was approached by Warren Samuels and Kluwer about editing a new book that would again address where things stand in labor economics. In proceeding with the development of this current book I was a struck by the extent to which the research thrust that was apparent in the early 1980s remains intact as we move toward the 21st century. The vast majority of scholarship in the labor subfield is dominated by the methodological orientation of applied neoclassical microeconomics, supplemented by incursions from the themes that occupy the so-called 'pure theorists,' particularly of the game theoretic variety. …

Buch. Condición: Neu. Neuware - Most queuing analyses performed in the literature are based on characterization of queueing phenomena in continuous-time items. Recently in the telecommunication industries, BISDN (broadband integrated services digital network) has received considerable attention since it can provide a common interface for future communication needs including video, data, and speech. Since information in BISDN is transported by means of dicsrete units of 53-octet ATM (asynchronous transfer mode) cells, interests in discrete-time systems have increased. Discrete-Time Models for Communication Systems Including ATM provides a general framework for queueing analyses of dicrete-time systems. After a brief look at past studies of discrete-time systems, a detailed description and analysis are presented for a generic discrete-time model with a single server, arbitrary service times and independent arrivals. The book then follows a less stringent approach and focuses more on the average statistics and on different queueing disciplines. Conventional first-in-out and last-in-first-out disciplines are discussed in terms of the average statistics. Systems with multiple classes of messages without class-dependent priorities are considered to establish a discrete-time conservation law. Multiple classes with priorities are also considered to derive performance measures of priority scheduling disciplines. Finally, a multi-queue system with cyclic service is analyzed in the context of round-robin service ordering. This is followed by analyses of discrete-time queueing systems with `more complicate' input and output processes. Specifically, single-server systems are investigated whereby either the arrivals or the server is subject to random interruptions. Results are mainly obtained in terms of generating functions and mean values of the principal performance measures. The influence of the nature of the arrival correlation and the server interruptionson the queueing behavior is discussed. Finally, the book explores queueing models directly associated with ATM switches and multiplexers. This book is a valuable reference and may be used as a text for and advanced course on the subject.…

Buch. Condición: Neu. Neuware - 1.1 Overview We are living in a decade recently declared as the 'Decade of the Brain'. Neuroscientists may soon manage to work out a functional map of the brain, thanks to technologies that open windows on the mind. With the average human brain consisting of 15 billion neurons, roughly equal to the number of stars in our milky way, each receiving signals through as many as 10,000 synapses, it is quite a view. 'The brain is the last and greatest biological frontier', says James Weston codiscoverer of DNA, considered to be the most complex piece of biological machinery on earth. After many years of research by neuroanatomists and neurophys iologists, the overall organization of the brain is well understood, but many of its detailed neural mechanisms remain to be decoded. In order to understand the functioning of the brain, neurobiologists have taken a bottom-up approach of studying the stimulus-response characteristics of single neurons and networks of neurons, while psy chologists have taken a top-down approach of studying brain func tions from the cognitive and behavioral level. While these two ap proaches are gradually converging, it is generally accepted that it may take another fifty years before we achieve a solid microscopic, intermediate, and macroscopic understanding of brain.…

Buch. Condición: Neu. Neuware - Insect Learning is a comprehensive review of a new field. Until recently, insects were viewed as rigidly programmed automatons; now, however, it is recognized that they can learn and that their behavior is plastic. This fundamental change in viewpoint is causing a re-examination of all aspects of the relationship between insects and their environment. This change in perspective is occurring at a time of heightened interest in brain function in both vertebrates and invertebrates. Insects potentially play a major role in this expanding area. Because of their experimental tractability and genetic diversity, they provide unique opportunities for testing hypotheses on the ecology and evolution of learning. As organisms of economic importance, they are perennial objects of research by both basic and applied scientists. Insect Learning covers both social and non-social insects from multiple perspectives. The book covers mechanisms; syntheses of work on physiology, behavior, and ecology; and micro- and macroevolution. The concluding section discusses future directions for research, including applications to pest management.…

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book will attempt to give a first synthesis of recent works con cerning reactive system design. The term 'reactive system' has been introduced in order to at'oid the ambiguities often associated with by the term 'real-time system,' which, although best known and more sugges tive, has been given so many different meanings that it is almost in evitably misunderstood. Industrial process control systems, transporta tion control and supervision systems, signal-processing systems, are ex amples of the systems we have in mind. Although these systems are more and more computerized, it is sur prising to notice that the problem of time in computer science has been studied only recently by 'pure' computer scientists. Until the early 1980s, time problems were regarded as the concern of performance evalu ation, or of some (unjustly scorned) 'industrial computer engineering,' or, at best, of operating systems. A second surprising fact, in contrast, is the growth of research con cerning timed systems during the last decade. The handling of time has suddenly become a fundamental goal for most models of concurrency. In particular, Robin Alilner 's pioneering works about synchronous process algebras gave rise to a school of thought adopting the following abstract point of view: As soon as one admits that a system can instantaneously react to events, i. e. 188 pp. Englisch.…
