Taschenbuch. Zustand: Neu. Neuware -This book shows amateur astronomers how to use one-shot CCD cameras, and how to get the best out of equipment that exposes all three color images at once. Because this book is specifically devoted to one-shot imaging, 'One-Shot Color Astronomical Imaging' begins by looking at all the basics - what equipment will be needed, how color imaging is done, and most importantly, what specific steps need to be followed after the one-shot color images are taken.What is one-shot color imaging Typically, astronomical cooled-chip CCD cameras record only one color at a time - rather like old-fashioned black & white cameras fitted with color filters. Three images are taken in sequence - in red, blue, and green light - and these are then merged by software in a PC to form a color image. Each of the three images must be taken separately through a suitable color filter, which means that the total exposure time for every object is more than tripled. When exposure times can run into tens of minutes or even hours for each of the three colors, this can be a major drawback for the time-pressed amateur.'One-Shot Color Astronomical Imaging' describes the most cost-effective and time-efficient way for any amateur astronomer to begin to photograph the deep-sky.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The Andromeda Galaxy ¿ Messier¿s M31 ¿ has an almost romantic appeal. It is the most distant object and the only extragalactic object that is visible to the unaided human eye. Now known to be about 2¿ million light-years away, it appears in the sky to be several times the width of the full Moon under good seeing conditions. The Andromeda Galaxy and the Rise of Modern Astronomy examines the astronomical studies of Andromeda and its importance to our developing knowledge of the universe. The book discusses how M31 was described both by the Ancients, but more importantly, by astronomers from the nineteenth century to the present.While at the start of the twentieth century the universe was thought of as a finite cosmos dominated by the Milky Way, the study of Andromeda galaxy shattered that image, leading ultimately to the conception of an infinite universe of countless galaxies and vast distances. Even today, M31 is a major focal point for new astronomical discoveries, and it also remains one of the most popular (and rewarding) celestial objects for amateur astronomers to observe and study. This book reveals the little-known history of M31 and the scientists who study it.For all who are interested in astronomy, the skies, and perhaps even the origins of the universe, The Andromeda Galaxy and the Rise of Modern Astronomy provides a first-of-its-kind accessible, informative, and highly readable account of how the study and observation of this celestial object has driven the development of astronomy from ancient times to the present.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -¿¿¿¿¿¿Now more than ever, marketing is assuming a key boundary-spanning role¿a role that also redefined the composition of the marketing organization. In this Brief, the marketing organization¿s integrative and mutually reinforcing components of marketing activities, customer value-creating processes, networks, and stakeholders are delineated within their boundary-spanning roles. Expanding upon his article published in the Journal of the Academy of Marketing Science in 2011, Tomas Hult draws thematic marketing insights from the integration of thirty-one organization theories to advance knowledge on the boundary-spanning marketing organization within four areas: strategic marketing resources, marketing leadership and decision making, network alliances and collaborations, and the domestic and global marketplace.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 88 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -¿¿¿Progressives need a balanced federal budget morethan Conservatives, because they believe that government has an important role toplay in modern life. Lack of a long term plan to move toward a sustainablebudget crowds out short term Progressive priorities: infrastructure spendinggreen technology, education and needed governmental interventions in the shortterm to support and improve our weak economy. The federal budget is unsustainable. For all the bluster of the debt ceilingdebate, the plan passed so far does not address the changes most obviouslyneeded if we are to ever have a balanced budget again: an increase in taxes andthe next steps on health reform to address the biggest driver of our long termbudget deficit, health care costs.Slowing the rate at which health care costs are growing is a necessary, but nota sufficient condition to developing a long range balanced budget. You shouldask any politician saying they think a balanced budget is a priority onequestion: what is your health reform plan Without one, they have no hope ofachieving their goal. This book offers progressives solutions to health care reform and a balanced budget, and will be of interest to academics, students and educated readers interested in politics, public policy andgovernment finance.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 124 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This symposium was not only a happy event for the University of Nebraska, but it marked a milestone in the history of the biological sciences here. The symposium cele in the most appropriate way possible, the creation of the new School of Life brated, Sciences and ushered in what I believe will be a period of substantial development for biology on this campus. I am immensely proud of the faculty of this new School, and I have every confidence that the School's reputation and achievements will continue to grow. As you all know, this university has had and still has distinguished scientists in the biological sciences and has offered fme programs at both the undergraduate and graduate level. But both the formation of the School of Ufe Sciences and the construction of the new Ufe Sciences Building promise a brighter future in this important area The School of Life Sciences was formed from the Departments of Botany, Micro biology, and Zoology, together with staff members in Biochemistry (from both the Department of Chemistry and from the former Department of Biochemistry and Nutri tion in the College of Agriculture) as well as staff members in the College of Agriculture's Department of Plant Pathology. Our whole notion was to build a core unit in biology that would cross the lines between the College of Arts and Sciences and the College of Agriculture in order to combine strengths which exist in both areas.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The study of animal behaviour, particularly from evolutionary and ecological viewpoints, has been one of the major growing points in biology over the last 10 to 15 years. The degree of quantitative rigour in theoretical, observational and experimental approaches to behaviour has increased dramatically. As more of the rapidly growing research literature be comes a basic requirement for students reading animal behaviour at undergraduate level, there is a need for a readily comprehensible text, covering all major aspects of behaviour study, to accom pany their courses. This book, based on my first, second and third year under graduate lectures at the University of No ttingham , is designed to meet that requirement. The book begins with a discussion of the physiological and anatomical bases of behaviour: the relationship between nervous system structure and function and behaviour; hormonal effects on behaviour; biological c1ocks; perceptual mechanisms; and stimulus filtering. This leadsto a consideration in Chapter 2 of how the animal integrates internal and external stimuli in making decisions about its behaviour and the way natural selection has shaped decision-making processes and the organisation of motivation. The first two chapters therefore deal with the instigation or causation of behaviour within the animal. Chapters 3 and 4 deal with developmental aspects of behaviour. Chapter 3 discusses behaviour genetics, inc1uding the relationship between specific genes and behaviour, the heritability of behaviour patterns, the site of gene action in the body and the evolutionary consequences of a genetic basis to behaviour.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This year, Orbis Scientiae 1976, dedicated to the Bicentennial of the United States of America, was devoted entirely to recent developments in high energy These proceedings contain nearly all of the physics. papers presented at Orbis, held at the Center for Theoretical Studies, University of Miami, during January 19-22, 1976. The organization of Orbis this year was due mainly to the moderators of the sessions, principally Sydney Meshkov, Murray Gell-Mann, Yoichiro Nambu, Glennys Farrar, Fred Zachariasen and Behram Kursunoglu, who was also chairman of the conference. The coherence of the various sessions is due to their efforts, and special thanks are due to Sydney Meshkov who was responsible for coor dinating many.of the efforts of the moderators and for including essentially all of the frontier developments in high energy physics. Because of the number of papers and their integrated length, it has been necessary to divide these proceedings into two volumes. An effort has been made to divide the material in the two volumes into fundamental questions (including the appearance of magnetic charge in particle physics) and recent high energy results and attendant phenomenology. These volumes were prepared by Mrs. Helga Billings, Mrs. Elva Brady and Ms. Yvonne Leber, and their dedication and skill are gratefully acknowledged. Their efforts v PREFACE during Orbis were supplemented by those of Mrs. Jacquelyn Zagursky, with our appreciation.

Taschenbuch. Zustand: Neu. Neuware -As the aquaculture industry has expanded throughout the world, it has embraced the experiences of many fields of study to meet increasing technological challenges. The complexities of modern hatchery methodology, more intensive growout systems, and the application of diverse biological and physical sciences to aquatic animal husbandry have reached beyona the ability of most aquaculturists to enjoy an in-depth knowledge of all phases of the aquaculture process. More importantly, in order for tne culturist to have at hand the information necessary to make basic decisions, it requires an extensive library of textbooks and scientific literature. The Aquaculture Desk Reference serves as a concise compila tion of tables, graphs, conversions, formulas and design specifica tions useful to the aquaculture industry. It also provides examples, in a straightforward manner, of how information in tabulature can be used to derive values for specific system design and process strategies. Tables and graphs in this volume also provide back ground documentation and authority for further reference. The Aquaculture Desk Reference is a convenient source book that will alleviate the need for an extensive personal library to access basic information useful for practicing aquaculturists. Many thanks to Mrs. Ruth Aldrich for her assistance in the preparation of this book. My family, friends and associates also deserve my special appreciation for their encouragement and sup port.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Applications that require a high degree of distribution and loosely-coupled connectivity are ubiquitous in various domains, including scientific databases, bioinformatics, and multimedia retrieval. In all these applications, data is typically voluminous and multidimensional, and support for advanced query operators is required for effective querying and efficient processing. To address this challenge, we adopt a hybrid P2P architecture and propose novel indexing and query processing algorithms. We present a scalable framework that relies on data summaries that are distributed and maintained as multidimensional routing indices. Different types of data summaries enable efficient processing of a variety of advanced query operators.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 96 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Since the publication of the previous volumes many new aspects of the physical and life sciences have been developed in which the properties of water play a dominant role. Although, according to its preface, Volume 5 was to be the last one of the treatise, these recent developments have led to a revision of that statement. The present volume and its companion, still in preparation, deal with topics that were already mentioned in the preface to Volume 5 as gaining in importance. The recent development of X-ray and, more particularly, neutron scattering techniques have led to studies of 'structure' in aqueous solutions of electrolytes on the one hand, and to the role of water in protein structure and function on the other. Both these topics have reached a stage where reviews of the present state of knowledge are useful. The application of ab initio methods to calculations of hydration and conformation of small molecules has a longer history, but here again a critical summary is timely. The role of solvent effects in reaction kinetics and mechanisms should have had a place in Volume 2 of this treatise, but, as sometimes happens, the author who had taken on this task failed tQ live up to his promise. However, since 1972 the physical chemistry of mixed aqueous solvents has made considerable strides, so that the belated discussion of this topic (by a new author) is built on evidence that was not available at the time of publication of Volume 2.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 472 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Almost all theories of fundamental interactions are nowadays based on the gauge concept. Starting with the historical example of quantum electrodynamics, we have been led to the successful unified gauge theory of weak and electromagnetic interactions, and finally to a non abelian gauge theory of strong interactions with the notion of permanently confined quarks. The. early theoretical work on gauge theories was devoted to proofs of renormalizability, investigation of short distance behaviour, the discovery of asymptotic freedom, etc . . , aspects which were accessible to tools extrapolated from renormalised perturbation theory. The second phase of the subject is concerned with the problem of quark confinement which necessitates a non-perturbative understanding of gauge theories. This phase has so far been marked by the introduc tion of ideas from geometry, topology and statistical mechanics in particular the theory of phase transitions. The 1979 Cargese Institute on 'Recent Developments on Gauge Theories' was devoted to a thorough discussion of these non-perturbative, global aspects of non-abelian gauge theories. In the lectures and seminars reproduced in this volume the reader wilf find detailed reports on most of the important developments of recent times on non perturbative gauge fields by some of the leading experts and innovators in this field. Aside from lectures on gauge fields proper, there were lectures on gauge field concepts in condensed matter physics and lectures by mathematicians on global aspects of the calculus of variations, its relation to geometry and topology, and related topics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 452 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The present book contains the Proceedings of a two day Symposium on Uremic Toxins organized at the University of Ghent in Belgium. A series of guest lectures, free communications and posters have been presented. An international audience of 163 scientists from 16 nationalities listened to and discussed extensively a spectrum of topics brought forward by colleagues and researchers who worked for many years in the field of Uremic Toxins. There is a striking contrast between all the new dialysis strategies available in the work to 'clean' the uremic patients and the almost non-progression of our knowledge on uremic toxins in the past decade. In this sense the symposium was felt by all participants as a new start for the research in the biochemical field of the definition of uremia. If the present volume would stimulate new work in this field in order to define uremia, or identify the uremic toxins, the purpose of the organizers would be maximally fulfilled.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Although 5-fluorouracil (Fura) is the drug of choice for the treat ment of patients with advanced colorectal cancer, this agent has limited effectiveness with a reported response rate of 10-20% and a duration of response of only 6-9 months. The large percentage of treatment failures with this agent has spurred a continuing effort to delineate the mechanism(s) of resistance to Fura and to evaluate approaches that would selectively modulate the therapeutic efficacy of this agent. The therapeutic efficacy of FUra has been attributed to its selec tive incorporation into RNA and to its inhibition of thymidylate syn thase, leading to potent inhibition of DNA synthesis. Studies of cell lines in vitro and model systems in vivo have demonstrated that although mechanism~sensitivity and resistanc; to Fura are multifactorial, in the presence of citrovorum factor (CF, 5-formyltetrahydrofolate) the site of action of Fura becomes predominantly the pronounced and pro longed inhibition of thymidylate synthase. This action is the result of stabilization of the covalent ternary complex between FdUMP, an active metabolite of FUra, 5,10-methylenetetrahydrofolates, and thymidylate synthase. This effect of CF is thus an example of the concept of meta bolic modulation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -It is now generally recognized that the field of combinatorics has, over the past years, evolved into a fully-fledged branch of discrete mathematics whose potential with respect to computers and the natural sciences is only beginning to be realized. Still, two points seem to bother most authors: The apparent difficulty in defining the scope of combinatorics and the fact that combinatorics seems to consist of a vast variety of more or less unrelated methods and results. As to the scope of the field, there appears to be a growing consensus that combinatorics should be divided into three large parts: (a) Enumeration, including generating functions, inversion, and calculus of finite differences; (b) Order Theory, including finite posets and lattices, matroids, and existence results such as Hall's and Ramsey's; (c) Configurations, including designs, permutation groups, and coding theory. The present book covers most aspects of parts (a) and (b), but none of (c). The reasons for excluding (c) were twofold. First, there exist several older books on the subject, such as Ryser [1] (which I still think is the most seductive introduction to combinatorics), Hall [2], and more recent ones such as Cameron-Van Lint [1] on groups and designs, and Blake-Mullin [1] on coding theory, whereas no compre hensive book exists on (a) and (b).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 492 pp. Englisch.

The abnor mality present during pregnancy is now accepted as what is inherited with the diabetic predisposition, or what can be recognized as the diabetic susceptibility. It occurs before hyperglycemia, during the phase of dy namic resistance to diabetes, during the prediabetic period. Prediabetes means before diabetes, and was applied for the first time by Mara~on in Spain, to signify the stage before hyperglycemia. Foglia in Argentina used the term in 1944 for his pancreatectomized rats.

Potter and Dr. Henry Pitot (at McCardle Laboratory in Madison, Wisconsin), Dr. Tetsuo Ono (then at McCardle Laboratory and now at the Japanese Foundation for Cancer Research in Tokyo, Japan) and Dr. Harold P. Morris (then at the National Cancer Institute and now at Howard University, Washington, D. C. ) decided that an experimental cancer model would be an invaluable tool to examine neoplastic changes in cells. Since they were study ing the various highly specific metabolic processes which are unique to liver tissues, they determined that a transplantable liver cancer model would be the ideal system to work with. This system would provide for comparison of normal liver tissue of the non-tumor bear ing animal, the tumor bearing animal's (host) liver and the liver cancer. Dr. Morris undertook a series of rat studies employing several chemicals known to cause liver cancer. Soon the first Morris hepatomas (#3683, 3924A, 5123) were being studied by several labs. During the next 18 years, Dr. Morris developed and transplanted numerous strains of hepatomas of which no two were identical. These tumors ranged from the very slowly-growing, highly differentiated cancer tissues, e. g. , 96l8A which is a diploid tumor containing gly cogen and a 'nearly normal' complement of enzymes, to a large group of rapidly-growing, poorly differentiated cancer tissues, e. g.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 788 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Some time ago a group of present and former collaborators of Professor John O'M. Bock ris, following a suggestion by Professor J. D. Mackenzie (Los Angeles), conceived the idea of an International Symposium devoted to reviewing the active and developing aspects of the science of electrochemistry. From this beginning has sprung the 'Electrochemistry Symposium-The Past Thirty and the Next Thirty Years,' which took place at Imperial College, London, from April 3-6, 1975. The plan for this symposium is unusual, since it features pairs of invited addresses, one to summarize the 'state of the art' and the other to suggest directions for future re search in particular aspects of electrochemistry. This volume of proceedings gives these papers in their fmal, considered, and fully referenced form, arranged in the sequence of their delivery at the symposium. Also in cluded are introductory addresses given by Professor Ubbelohde, Professor Frumkin, Dr. Egan, and Dr. Inman. Both aspects of nearly every topic, plus the discussions, are integrated in a Report or Summary. A synopsis of the matters raised at the symposium and prepared by Professor John O'M.

Neuware -Second order equations with nonnegative characteristic form constitute a new branch of the theory of partial differential equations, having arisen within the last 20 years, and having undergone a particularly intensive development in recent years. An equation of the form (1) is termed an equation of second order with nonnegative characteristic form on a set G, kj if at each point x belonging to G we have a (xHk~j ~ 0 for any vector ~ = (~l' . '~m)' In equation (1) it is assumed that repeated indices are summed from 1 to m, and x = (x l' ¿¿¿ , x ). Such equations are sometimes also called degenerating m elliptic equations or elliptic-parabolic equations. This class of equations includes those of elliptic and parabolic types, first order equations, ultraparabolic equations, the equations of Brownian motion, and others. The foundation of a general theory of second order equations with nonnegative characteristic form has now been established, and the purpose of this book is to pre sent this foundation. Special classes of equations of the form (1), not coinciding with the well-studied equations of elliptic or parabolic type, were investigated long ago, particularly in the paper of Picone [105], published some 60 years ago.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The papers in the present volume were presented on November lst-3rd, 1973, in Rome on the occasion of an International Post graduate Course sponsored by the Italian Society for the Study of Atherosclerosis, the Istituto Superiore di Sanita, and the Fondazione Giovanni Lorenzini. The purpose of this course was to gather information and to draw attention to the role of diet in the pathogenesis of experi mental and human arteriosclerosis, as well as its prevention and therapy. Konrad Bloch, in the opening lecture, emphasized the features unique to fatty acid synthesis in animal tissues and discussed the importance of comparative biochemical research in the study of control mechanisms of lipid biosynthesis. The lectures in the morning were followed in the afternoon by short practical demonstrations (R. Angelico, O. Lostia, A. Menotti, D.H. Blankenhorn, A. Ferro Luzzi). Particular attention was paid to the problem of dietary edu cation in Italy, during a round-table discussion on November 2nd (G. Bergami, G. Ricci, G. Crepaldi, F. Fidanza, S.F. Feruglio, M. Proia, A. Mariani, L. Ribolzi). The educational purpose of the course is obvious in Italy, a country where the people had been accustomed for centuries to the intake of a virtually nonatherogenic diet, until, quite recently, the migration from agricultural to industrialized areas assumed sociologically significant levels. It was then found that the lipoproteinemic patterns of the migrated population had shifted toward higher levels.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The topics in this book represent the presentations given at the Fifth Annual Meeting entitled 'Cardiac Surgery: Current Issues' held at the Frenchman's Reef Beach Resort, St. Thomas, U.S. Virgin Islands, November 18-20, 1993. This symposium was sponsored by the Division of Cardiothoracic Surgery, the School of Cardiovascular Perfusion and the Department of Nursing Education and Quality Assurance of Cooper Hospital/University Medical Center, the University of Medicine and Dentistry of New Jersey, Robert Wood Johnson Medical School, Camden, New Jersey, as well as the Academy of Medicine of New Jersey. Chapter authors were charged with the task of writing brief overviews of major issues related to the field of cardiac surgery. The book is specifically tailored to the needs of cardiothoracic surgeons, cardiovascular perfusion ists, allied health professionals and nursing personnel involved in all phases of caring for the cardiac surgical patient. Although intended as a reference source with emphasis on up-dated approaches applied in cardiac surgery, it is hoped that the discussion of these topiCS will compliment other texts and manuscripts. Obviously, a book of this length cannot cover the whole multidisciplinary and complex field of cardiac surgery. However, co-editors are certain that the annual appearance of this text will highlight comprehensive, new and Interesting approaches to the field of cardiac surgery.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 208 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -At 8:15 A.M., August 6, 1945, the Enola Gay released her load. For forty three seconds, the world's first atomic bomb plunged through six miles of clear air to its preset detonation altitude. There it exploded, destroying Hiroshima and eighty thousand of her citizens. No war had ever seen such instant devastation. Within nine days Japan surrendered. World War II was over and a nuclear arms race had begun. Fifty years later, the National Air and Space Museum was in the final stages of preparing an exhibition on the Enola Gay's historic mission when eighty-one members of Congress angrily demanded cancellation of the planned display and the resignation or dismissal of the museum's director. The Smithsonian tnstitution, of which the National Air and Space Museum is a part, is heavily dependent on congressional funding. The Institution's chief executive, Smithsonian Secretary I. Michael Heyman, in office only four months at the time, scrapped the exhibit as requested, and promised to personally oversee a new display devoid of any historic context. In the wake of that decision I resigned as the museum's director and left the Smithsonian.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 504 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Some 10 years ago, Leo Apostel presented an analysis of developments taking place in genetic epistemology and artificial intelligence, and re marked that the two disciplines appeared to be converging, without one dominating or assimilating the other. In his view, significant formal and experimental progress would be required in the post-Piagetian era: ge netic epistemology would need to take into account developments in artificial intelligence, while remaining an independent discipline at the frontiers of biology, logic, and psychology. The work of David Leiser and Christiane Gillieron, both psychol ogists with a Genevan training who are concerned by the procedural aspects of intelligence, is an important contribution. Their studies, which open up new theoretical perspectives, are carried out with metic ulous attention to research methodology. Going beyond merely ad dressing criticisms about the status of Piagetian operational structures, their work will help fill the gap between genetic epistemology and cog nitive science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Efficiency is one of the most frequently used terms in thermodynamics, and it indicates how well an energy conversion or process is accomplished. Efficiency is also one of the most frequently misused terms in thermodynamics and is often a source of misunderstanding. This is because efficiency is often used without being properly defined first. This book intends to provide a comprehensive evaluation of various efficiencies used for energy transfer and conversion systems including steady-flow energy devices (turbines, compressors, pumps, nozzles, heat exchangers, etc.), various power plants, cogeneration plants, and refrigeration systems. The book will cover first-law (energy based) and second-law (exergy based) efficiencies and provide a comprehensive understanding of their implications. It will help minimize the widespread misuse of efficiencies among students and researchers in energy field by using an intuitive and unified approach for defining efficiencies. The book will be particularly useful for a clear understanding of second law (exergy) efficiencies for various systems. It may serve as a reference book to the researchers in energy field. The definitions and concepts developed in the book will be explained through illustrative examples.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Machine learning and nonparametric function estimation procedures can be effectively used in forecasting. One important and current application is used to make forecasts of ¿future dangerousness' to inform criminal justice decision. Examples include the decision to release an individual on parole, determination of the parole conditions, bail recommendations, and sentencing. Since the 1920s, 'risk assessments' of various kindshave been used in parole hearings, but the current availability of large administrative data bases, inexpensive computing power, and developments in statistics and computer science have increased their accuracy and applicability.In this book, these developments are considered with particular emphasis on the statistical and computer science tools, under the rubric of supervised learning, that can dramatically improve these kinds of forecasts in criminal justice settings. The intended audience is researchers in the social sciences and data analysts in criminal justice agencies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 128 pp. Englisch.
