Taschenbuch. Condición: Neu. Neuware -A technological book is written and published for one of two reasons: it either renders some other book in the same field obsolete or breaks new ground in the sense that a gap is filled. The present book aims to do the latter. On my return from industry to an academic career, I started writing this book because I had seen that a gap existed. Although a great deal of information appeared in the published literature about various technical aspects of advanced manufacturing technology (AMT), surprisingly little had been written about the systems con text within which the sophisticated hardware and software of AMT are utilized to increase efficiency. Therefore, I have attempted in this book to show how structured approaches in the design and evaluation of modern manufacturing plant may be adopted, with the objective of improving the performance of the factory as a whole. I hope this book will be a contribution to the newly recognized, multidisciplinary engineering function known as manufacturing sys tems engineering. The text has been designed specifically to demonstrate the systems aspects of modern manufacturing operations, including: systems con cepts of manufacturing operation; manufacturing systems modelling and evalua tion; and the structured design of manufacturing systems~ One of the major difficulties associated with writing a text of this nature stems from the diversity of the topics involved. I have attempted to solve this problem by adopting an overall framework into which the relevant topics are fitted.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 432 pp. Englisch.

Buch. Condición: Neu. Neuware -Writing this book would have been impossible without the help of certain institutions and persons. For a gas-producing and oil-processing country like the Netherlands, there was surprisingly very little, publicly available, research material. Public libraries' collections contained, with a certain degree of inconsistency, little of the more specialised sources. I would therefore like to express my gratitude towards Royal Dutch Shell, and especially the library staff in The Hague, for allowing me to use the company's library, thanking them for their assistance in finding and supplying the required data. I am also grateful for the financial assistance of the 'Nederlandse organisatie voor wetenschappelijk onderzoek' (NWO) and the Faculty of Law of the University of Leiden. They provided the financial means to work a (crucial) month in the very well equipped library of the Oxford Institute for Energy Studies. I am indebted to the staff of the Oxford Institute for Energy Studies, and particularly to Robert Mabro and Jeremy Turk, for their comments, support, and friendship. After I spent a month in the Institute in July 1989, I was able to return for two five-month periods in 1990 and 1991. For both periods, the Oxford Institute and the Leiden Law Faculty provided me with the necessary means. I would also like to express special gratitude to some people who have been a great support and supplied me with valuable comments at various stages of the study. 240 pp. Englisch.

Buch. Condición: Neu. Neuware -This book brings together much of the best policy-oriented research on state and local mortgage revenue bond (MRB) programs. Most of this re search was conducted to evaluate the impact of MRB subsidies on housing markets and potential home buyers. All of the research is concerned with the 'so what' question often ignored by economists: it addresses the implications of the research results for public policy decisions concerning MRBs. The need for this book becomes apparent when reading the transcripts of congressional hearings on MRBs. At those hearings, the policy debate seems underinformed. Aside from discussions of the General Accounting Office's periodic evaluations of MRB programs and impassioned rebuttals by MRB proponents, the hearing testimony consists mostly of assertions and anecdotal evidence, with some 'yes MRBs work' and 'no they don't' exchanges. Although the research in this book may not improve the level of the policy debate on MRBs, it can inform decision makers, experts, and citizens interested in housing policy about issues that should be examined when considering the future of MRBs. Also, it can point other researchers interested in housing policy in the direction of the questions about MRB programs that need additional attention.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Buch. Condición: Neu. Neuware -In the last ten years offshore mineral exploration programmes have increasingly concentrated on the 200 mile Exclusive Economic Zones adjacent to coastal states. This book gives an integrated treatment of the various mineral types occuring in these zones, their genesis, distribution and economic importance. The book opens with a broad overview of the subject and discusses the legislative issues relevant to marine and mineral exploitation. Chapters then deal in turn with aggregates, placers, precious coral, phosphorites, manganese nodules, cobalt-rich manganese crusts and hydrothermal deposits. An international set of case studies illustrates each type of deposit, many studies based on the author's own experience in marine mineral evaluation programmes around the world during the past 25 years.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condición: Neu. Neuware -Gertrudis Van de Vijver Seminar of Logic and Epistemology University of Ghent Before being classified under the fashionable denominators of complexity and chaos, self-organization and autonomy were intensely inquired into in the cybernetic tradition. Despite all rejections that cybernetics has gone through in the second half of this century, today its importance is more and more recognized. Its decisive influence for connectionist theories, autopoietic and constructivist theories, for different forms of applied or experimental epistemology, is being more and more understood and generally accepted. It is mainly due to the success of connectionist models that we observe today a revival of interest for cybernetics. The 1943 article by McCulloch and Pitts is evidently a founding article. Cybernetics has however a much broader interest than the one linked to technical-mathematical details relevant to the construction of networks. For instance, the evolution from first to second order cybernetics, the ways of approaching biological and cognitive phenomena in the latter and the limits that were formulated there, are particularly meaningful to understand current developments and divergences in connectionism. A nuanced picture of cybernetic's history and its present state is therefore clearly epistemologically essential.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Condición: Neu. Neuware -The field of structural optimization is still a relatively new field undergoing rapid changes in methods and focus. Until recently there was a severe imbalance between the enormous amount of literature on the subject, and the paucity of applications to practical design problems. This imbalance is being gradually redressed. There is still no shortage of new publications, but there are also exciting applications of the methods of structural optimizations in the automotive, aerospace, civil engineering, machine design and other engineering fields. As a result of the growing pace of applications, research into structural optimization methods is increasingly driven by real-life problems. t-.Jost engineers who design structures employ complex general-purpose software packages for structural analysis. Often they do not have any access to the source program, and even more frequently they have only scant knowledge of the details of the structural analysis algorithms used in this software packages. Therefore the major challenge faced by researchers in structural optimization is to develop methods that are suitable for use with such software packages. Another major challenge is the high computational cost associated with the analysis of many complex real-life problems. In many cases the engineer who has the task of designing a structure cannot afford to analyze it more than a handful of times.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 508 pp. Englisch.

Buch. Condición: Neu. Neuware -The debate between the proponents of 'classical' and 'Bayesian' statistica} methods continues unabated. It is not the purpose of the text to resolve those issues but rather to demonstrate that within the realm of actuarial science there are a number of problems that are particularly suited for Bayesian analysis. This has been apparent to actuaries for a long time, but the lack of adequate computing power and appropriate algorithms had led to the use of various approximations. The two greatest advantages to the actuary of the Bayesian approach are that the method is independent of the model and that interval estimates are as easy to obtain as point estimates. The former attribute means that once one learns how to analyze one problem, the solution to similar, but more complex, problems will be no more difficult. The second one takes on added significance as the actuary of today is expected to provide evidence concerning the quality of any estimates. While the examples are all actuarial in nature, the methods discussed are applicable to any structured estimation problem. In particular, statisticians will recognize that the basic credibility problem has the same setting as the random effects model from analysis of variance.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Buch. Condición: Neu. Neuware -In this volume we have included some contributions among the plenary lectures, oral presentations and posters that have been presented at the 1st Joint Greek-Italian Meeting on 'The Chemistry of Biological systems and Molecular Chemical Engineering' organized at Loutraki, Club Poseidon, Greece 1990. We hope similar meetings will follow every two years alternating between the two countries in order to strengthen the scientific ties among the scientists working in this field. The inter disciplary aspect of the meeting has been evident by the wide presence of scientists in bioinorganic, bio-organic, biological fields and molecular engineers who will get together and exchange ideas and experiences. We take this opportunity to thank the Greek Chemical Society, the Italian Chemical Society, the 'Gruppo Interdivisionale di Chimica dei Sistemi e dei Processi Biologici', Consiglio Nazionale delle Ricerche, Nuclear Research Center 'Demokritos' and the Greek Ministry for Research and Technology.

Buch. Condición: Neu. Neuware -This monograph is written within the framework of the quantum mechanical paradigm. It is modest in scope in that it is restricted to some observations and solved illustrative problems not readily available in any of the many standard (and several excellent) texts or books with solved problems that have been written on this subject. Additionally a few more or less standard problems are included for continuity and purposes of comparison. The hope is that the points made and problems solved will give the student some additional insights and a better grasp of this fascinating but mathematically somewhat involved branch of physics. The hundred and fourteen problems discussed have intentionally been chosen to involve a minimum of technical complexity while still illustrating the consequences of the quantum-mechanical formalism. Concerning notation, useful expressions are displayed in rectangular boxes while calculational details which one may wish to skip are included in square brackets. Beirut HARRY A. MAVROMATIS June, 1985 IX Preface to Second Edition More than five years have passed since I prepared the first edition of this mono graph. The present revised edition is more attractive in layout than its predecessor, and most, if not all of the errors in the original edition (many of which were kindly pointed out by reviewers, colleagues, and students) have now been corrected. Additionally the material in the original fourteen chapters has been extended with significant additions to Chapters 8, 13, and 14.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Buch. Condición: Neu. Neuware -In recent years slugs have become increasingly important, partly because several species are agricultural and horticultural pests and partly because theyhave proved to be useful experimental animals, particularly in the field of neurophysiology. Most of the early works which included slugs were essentially taxonomic but the book byTaylor (1902-1907) contained a great deal of biological information about slugs, some of which is still relevant today. The publication of the book by Runham and Hunter (1970) represented a milestone in slug research, providing a comprehensive survey of current knowledge about slugs. The book by Godan (1983) on snailsand slugswas mainly concerned with theeconomic importanceof theseanimals. The purpose of the present book is to present a review of current knowledgeofthebiologyandecologyofslugs, togetherwith theirstatusand control as pests. Although relatively little is known about the biology and ecology of tropical slugs and most information is taken from work on European slugs, the European pest species have become widely distributed throughout temperate regions and this book should be of interest world wide. It is written as a source of information for people seeking to control slug pests and, also, for those wishing to use slugs for research or teaching purposes. The book is intended particularly to provide a starting point for those beginning research on slugs and an extensive bibliography has been provided.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 444 pp. Englisch.

Buch. Condición: Neu. Neuware -This book has a fundamental relationship to the International Seminar on Fuzzy Set Theory held each September in Linz, Austria. First, this volume is an extended account of the eleventh Seminar of 1989. Second, and more importantly, it is the culmination of the tradition of the preceding ten Seminars. The purpose of the Linz Seminar, since its inception, was and is to foster the development of the mathematical aspects of fuzzy sets. In the earlier years, this was accomplished by bringing together for a week small grou ps of mathematicians in various fields in an intimate, focused environment which promoted much informal, critical discussion in addition to formal presentations. Beginning with the tenth Seminar, the intimate setting was retained, but each Seminar narrowed in theme; and participation was broadened to include both younger scholars within, and established mathematicians outside, the mathematical mainstream of fuzzy sets theory. Most of the material of this book was developed over the years in close association with the Seminar or influenced by what transpired at Linz. For much of the content, it played a crucial role in either stimulating this material or in providing feedback and the necessary screening of ideas. Thus we may fairly say that the book, and the eleventh Seminar to which it is directly related, are in many respects a culmination of the previous Seminars.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.

Buch. Condición: Neu. Neuware -Advanced Mathematical Thinking has played a central role in the development of human civilization for over two millennia. Yet in all that time the serious study of the nature of advanced mathematical thinking ¿ what it is, how it functions in the minds of expert mathematicians, how it can be encouraged and improved in the developing minds of students ¿ has been limited to the reflections of a few significant individuals scattered throughout the history of mathematics. In the twentieth century the theory of mathematical education during the compulsory years of schooling to age 16 has developed its own body of empirical research, theory and practice. But the extensions of such theories to more advanced levels have only occurred in the last few years. In 1976 The International Group for the Psychology of Mathematics (known as PME) was formed and has met annually at different venues round the world to share research ideas. In 1985 a Working Group of PME was formed to focus on Advanced Mathematical Thinking with a major aim of producing this volume. The text begins with an introductory chapter on the psychology of advanced mathema- cal thinking, with the remaining chapters grouped under three headings: ¿ the nature of advanced mathematical thinking, ¿ cognitive theory, and ¿ reviews of the progress of cognitive research into different areas of advanced mathematics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 314 pp. Englisch.

Buch. Condición: Neu. Neuware -Berkeley's philosophy has been much studied and discussed over the years, and a growing number of scholars have come to the realization that scientific and mathematical writings are an essential part of his philosophical enterprise. The aim of this volume is to present Berkeley's two most important scientific texts in a form which meets contemporary standards of scholarship while rendering them accessible to the modern reader. Although editions of both are contained in the fourth volume of the Works, these lack adequate introductions and do not provide com plete and corrected texts. The present edition contains a complete and critically established text of both De Motu and The Analyst, in addi tion to a new translation of De Motu. The introductions and notes are designed to provide the background necessary for a full understanding of Berkeley's account of science and mathematics. Although these two texts are very different, they are united by a shared a concern with the work of Newton and Leibniz. Berkeley's De Motu deals extensively with Newton's Principia and Leibniz's Specimen Dynamicum, while The Analyst critiques both Leibnizian and Newto nian mathematics. Berkeley is commonly thought of as a successor to Locke or Malebranche, but as these works show he is also a successor to Newton and Leibniz.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Buch. Condición: Neu. Neuware -This book contains twenty-eight papers by participants in the NATO Advanced Study Institute (ASI) on 'Cognitive and Linguistic Aspects of Geographic Space,' held in Las Navas del Maxques, Spain, July 8-20, 1990. The NATO ASI marked a stage in a two-year research project at the U. S. National Center for Geographic Infonnation and Analysis (NCOIA). In 1987, the U. S. National Science Foundation issued a solicitation for proposals to establish the NCGIA-and one element of that solicitation was a call for research on a 'fundamental theory of spatial relations'. We felt that such a fundamental theory could be searched for in mathematics (geometry, topology) or in cognitive science, but that a simultaneous search in these two seemingly disparate research areas might produce novel results. Thus, as part of the NCGIA proposal from a consortium consisting of the University of California at Santa Barbara, the State University of New York at Buffalo, and the University of Maine, we proposed that the second major Research Initiative (two year, multidisciplinary research project) of the NCOIA would address these issues, and would be called 'Languages of Spatial Relations' The grant to establish the NCOIA was awarded to our consortium late in 1988.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 528 pp. Englisch.

Buch. Condición: Neu. Neuware -The ciliated protozoa are important members of the interstitial biotope by virtue of their numbers and biomass. These single celled organisms form complex communities in the spaces between sandgrains in many marine sediments. Despite their important role in benthic ecology, there has been a lack of detailed studies on this large and fascinating group. Although difficult and demanding to work with, the most important aspect that has hampered research on these fragile organisms has been the lack of a suitable identification guide.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 370 pp. Englisch.

Buch. Condición: Neu. Neuware -Tea is a unique crop and, incidentally, a very interesting and attractive one. The tea bush, its cultivation and harvesting do not fit into any typical cropping pattern. Moreover, its processing and marketing are specific to tea. Thus the Tea Industry stands apart and constitutes a self contained entity. This is reflected in the title given to this book, Tea: Cultivation to consumption, and its treatment of the subject. The book is logically planned - starting with the plant itself and finishing with the traditional'cuppa'. Every aspect of tea production is covered, inevitably some in greater detail than others. However, it gives an authentic and comprehensive picture of the tea industry. The text deals in detail with cultural practices and research, where desirable, on a regional basis. The technology of tea cultivation and processing has been developed within the industry, aided by applied research which was largely financed by the tea companies themselves. This contributed to a technically competent industry but tended to bypass the more academic and fundamental investigations which might bring future rewards. The sponsorship of research has now widened and the range and depth of tea research has increased accordingly. The editors and authors of this book have played their part in these recent developments which are well reported in the book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 796 pp. Englisch.

Buch. Condición: Neu. Neuware -Anoxic basins are ofgreat interest to oceanographersofall disciplines. Theirextreme conditionsresult from acombinationofhigh oxygen utilization and restricted circulation. It is necessery to understand present -day anoxic environments ifwe are to understand the early evolution of the oceans (e.g. SiIlen, 1965). Sarmiento et al.(1988a) explored the causes of anoxia in the global ocean, which is in effect a 'closed' basin and in marginal seas such as the Eastern Mediterranean (Sarmiento et al. 1988b). Anoxic conditions have been proposed toexist in various ocean basins at different times in the geological past (e.g. the Crataceous period; Weissert, 1981) and possibly as recent as the last glacial maximum (e.g., Sarmiento and Toggweiler,1984). The modern Black Sea has been considered as the type anoxic basin. It is the world's 2 3 largest permanaently anoxic basin (area = 423,000 km ; volume = 534,000 km ) and is thought to be aquasi-steady state system. It is extremely isolated from the rest ofthe world's oceans. Only the narrow and shallow Bosporus Strait provides water exchange with the Mediterranean. Concentrationsofhydrogen sulfide reach valuesof350 Mm in the deep water and the oxygen-hydrogen sulfide Interface exists between 80 and 200m waterdepth. The hydrographic regime is characterized by low salinity surface water of riverine origin overlying high salinity deep waterofMediterranean origin. Asteep pycnocline is the primary phycical barrier to mixing and is the origin of the stability of the anoxic interface.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 508 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The purpose of this book is to bring together the most recent knowledge concerning the genetic improvement of ornamental plant species. Active researchers of many aspects of the genetics and breeding of these species have written chapters organized into three sections: Cytogenetics, Quantitative Genetics and Molecular Genetics. These titles identify the basic tools used in a variety of breeding situations. Some are traditional and well established; others offer new and exciting challenges for the future. vii Introduction The purpose of this book is to bring together recent knowledge concerning the genetic improvement of ornamental plant species. In the 20th century flower breeding has become widespread leading to many improvements in phenotypic and production characteristics of ornamental species. These methods depends on the creation and subsequent selection of genetic vari ability. Lack of variability in gene pools has been a chief limitation to the success of flower breeding. Recent progress in molecular biology makes it possible to add genetically well-defined characteristics to gene pools, thus increasing the potential for genetic improvement. These methods also enable the specific silencing of genetic information to accomplish an intentional loss of function. This book compiles current knowledge of the cytogenetics, quantitative genetics, and molecular genetics of ornamental plant species. The three sections identify the basic tools used in a variety of breeding situations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 444 pp. Englisch.

As a major source of information for reducing uncertainty in the alJocation of merit based educational, training, and employment opportunities, testing affects the life chances of individuals. Moreover, testing inOuences the way in which our societyjudgesitselfandprovides for ourcollective future. Test scores may determine a child's admission to lcindergarten and promotion to the fIrst grade. Most states award the high school diploma only ifa student has passed a minimum competency test. Major institutions of higher education typically require applicants to supplement their records of academic achievement with scores on college admissions tests. In the labor market, as a condition of employment or assignment to training programs, more and more employers are requiring workers to sit for personnel selection tests. Additionally, it has become commonplace to use test scores to calibrate our national sociopolitical condition and our capacity to compete with other countries in the global economy. In short, with increasing frequency and intensity, scores on examinations that purport to be objective and precise measures of individual knowledge, abilities, and potential are playing a critical role in the opportunity marketplace. Similarly, test scores are exercising growing influence in assessments of our social and economic institutions and in policy decisions about the relative invesunents that should be made in each. In all these instantiations, test scores are at the center of high-stakes decision making about the future of individuals and of the nation itself.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

Neuware -Members of the family Cyprinidae dominate most of the aquatic habitats of Europe, from eutrophic warm water ponds to mountain lakes. The family comprises generalists and specialists, herbivorous, planktovorous and even one piscivorous species; slow-moving grazers as well as fast-swimming inhabitants of the pelagial of lakes. Due to their diversity and abundance, cyprinids play key roles in every ecosystem in which they occur. Being of little economic importance, however, the family has for the most part failed to arouse keen scientific interest.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.
