Taschenbuch. Zustand: Neu. Neuware -Advances in Non-Linear Modeling for Speech Processing includes advanced topics in non-linear estimation and modeling techniques along with their applications to speaker recognition.Non-linear aeroacoustic modeling approach is used to estimate the important fine-structure speech events, which are not revealed by the short time Fourier transform (STFT). This aeroacostic modeling approach provides the impetus for the high resolution Teager energy operator (TEO). This operator is characterized by a time resolution that can track rapid signal energy changes within a glottal cycle.The cepstral features like linear prediction cepstral coefficients (LPCC) and mel frequency cepstral coefficients (MFCC) are computed from the magnitude spectrum of the speech frame and the phase spectra is neglected. To overcome the problem of neglecting the phase spectra, the speech production system can be represented as an amplitude modulation-frequency modulation (AM-FM) model. To demodulate the speech signal, to estimation the amplitude envelope and instantaneous frequency components, the energy separation algorithm (ESA) and the Hilbert transform demodulation (HTD) algorithm are discussed.Different features derived using above non-linear modeling techniques are used to develop a speaker identification system. Finally, it is shown that, the fusion of speech production and speech perception mechanisms can lead to a robust feature set.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The present NATO Advanced Study Institute held in CARGESE (Corsica) from Au gust 8th to August 18th, 1989 was devoted to Hadronic Physics. We tried to give this school a key educational role in this new and rapidly developing interdisciplinary field.

Taschenbuch. Zustand: Neu. Neuware -This book is the result of an informal association between the editors which extends back to 1974. At the beginning, it was a tenuous alliance between physicians in quite different medical subspecialties-urology and psychiatry. As the alliance was forged, subspecialty rivalries and mistrust were replaced by a common clinical interest in the diagnosis and treatment of erectile problems. We quickly became aware of the high prevalence of such disorders, how poorly prepared we were to make accurate and re sponsible diagnosis and treatment plans, and how complicated an etiol ogical diagnosis could prove to be. A variety of biological and psychological influences bear on sexual function, and in many clinical contexts, diagnosis and treatment planning involves consideration of complex interactive var iables. The need for an expanded multidisciplinary team became obvious. The requisite knowledge base extended across too many subspecialty boundaries, and the necessary information was not available in a conve nient source. As we began accumulating the information base, we became aware that this information might be of value to other physicians. The authors enjoy the luxury of an academic setting in which special expertise can be readily assembled. Such resources are often unavailable to the physician in practice. Thus, it is our hope that this text can serve as a multi specialty team for the physician in solo practice. R.

Taschenbuch. Zustand: Neu. Neuware -An intense charged particle beam can be characterized as an organized charged particle flow for which the effects of beam self-fields are of major importance in describing the evolution of the flow. Research employing such beams is now a rapidly growing field with important applications ranging from the development of high power sources of coherent radiation to inertial confinement fusion. Major programs have now been established at several laboratories in the United States and Great Britain, as well as in the USSR, Japan, and several Eastern and Western European nations. In addition, related research activities are being pursued at the graduate level at several universities in the US and abroad. When the author first entered this field in 1973 there was no single reference text that provided a broad survey of the important topics, yet contained sufficient detail to be of interest to the active researcher. That situation has persisted, and this book is an attempt to fill the void. As such, the text is aimed at the graduate student, or beginning researcher; however, it contains ample information to be a convenient reference source for the advanced worker.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book is a major revision and extension of my earlier book, Experimental Psychology and Human Aging, which appeared in 1982. The intervening years have seen a remarkable expansion of psychological research on human aging, especially on topics dealing with cognition. They have also seen research on cognitive aging gain increasing importance within the mainstream of basic cognitive research. As my lecture notes for my course in the psychology of aging grew, so did my apprehension regarding the task ahead of me in revis ing the first edition. The research explosion in cognitive aging forced several major changes in content from the first to the second edition. Two chapters on learning and memory in the first edition were necessarily expanded to six chapters in the present edition. Similarly, the single prior chapter on percep tion and attention became two chapters, as did the single prior chapter on thinking. Another change from the first edition is in the addition of some review of the effects of abnormal aging on various cognitive processes, parti cularly in regard to memory functioning. To keep the revision within reason able length, some sacrifices had to be made. The multiple chapters on metho dology and theory in the first edition were condensed into the present, single chapter. However, the major topics from the first edition were retained and, in fact, added to by the inclusion of important topics and issues that emerged over the past eight years.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 872 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The calculus of variations, whose origins can be traced to the works of Aristotle and Zenodoros, is now Ii vast repository supplying fundamental tools of exploration not only to the mathematician, but-as evidenced by current literature-also to those in most branches of science in which mathematics is applied. (Indeed, the macroscopic statements afforded by variational principles may provide the only valid mathematical formulation of many physical laws. ) As such, it retains the spirit of natural philosophy common to most mathematical investigations prior to this century. How ever, it is a discipline in which a single symbol (b) has at times been assigned almost mystical powers of operation and discernment, not readily subsumed into the formal structures of modern mathematics. And it is a field for which it is generally supposed that most questions motivating interest in the subject will probably not be answerable at the introductory level of their formulation. In earlier articles,1,2 it was shown through several examples that a complete characterization of the solution of optimization problems may be available by elementary methods, and it is the purpose of this work to explore further the convexity which underlay these individual successes in the context of a full introductory treatment of the theory of the variational calculus. The required convexity is that determined through Gateaux variations, which can be defined in any real linear space and which provide an unambiguous foundation for the theory. 384 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -By itself or in combination with an affective disorder, early onset schizophrenia (EOS) ¿ the onset of symptoms before 18 years of age ¿ can create severe deficits in young people¿s academic performance, family and peer relationships, and even the ability to acquire new skills. The relative rarity of the condition, meanwhile, can leave school personnel unsure of how to meet ¿ or even recognize ¿ student needs.Identifying, Assessing, and Treating Early Onset Schizophrenia at School emphasizes the importance of providing teachers and students alike with the support needed to enhance academic performance and improve social skills of children and adolescents with EOS within educational settings. In addition, its evidence-based framework enables school professionals to achieve greater confidence and accuracy in identifying students with EOS and provide appropriate services, both in special education and general classes.In this authoritative and accessible volume, experts offer the most salient information on early onset schizophrenia, including:Contributing factors and risk factors.Prevalence and epidemiology.Screening and assessment procedures.Guidelines for determining eligibility for special education programs under IDEIA and Section 504.Latest findings on school-based and off-campus interventions for EOS.A useful resource appendix.Identifying, Assessing, and Treating Early Onset Schizophrenia at School gives school psychologists and allied education professionals both a practical understanding of this disabling condition and the most up-to-date strategies for providing earlier and effective interventions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Since the 1960s, x-ray fluorescence spectrometry (XRF), both wavelength and energy-dispersive have served as the workhorse for non-destructive and destructive analyses of archaeological materials. Recently eclipsed by other instrumentation such as LA-ICP-MS, XRF remains the mainstay of non-destructive chemical analyses in archaeology, particularly for volcanic rocks, and most particularly for obsidian. In a world where heritage and repatriation issues drive archaeological method and theory, XRF remains an important tool for understanding the human past, and will remain so for decades to come.Currently, there is no comprehensive book in XRF applications in archaeology at a time when the applications of portable XRF and desktop XRF instrumentation are exploding particularly in anthropology and archaeology departments worldwide.The contributors to this volumeare the experts in the field, and most are at the forefront of the newest applications of XRF to archaeological problems. Itcovers all relevant aspects of the field for thoseusing the newest XRF technologies to deal with very current issues in archaeology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

His cases of exploration and are chosen very carefully and deliberately. The textbook achieves its purpose of taking new students of complex algebraic geometry through this a deep yet broad introduction to a vast subject, eventually bringing them to the forefront of the topic via a non-intimidating style.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Graphical models in their modern form have been around since the late 1970s and appear today in many areas of the sciences. Along with the ongoing developments of graphical models, a number of different graphical modeling software programs have been written over the years. In recent years many of these software developments have taken place within the R community, either in the form of new packages or by providing an R interface to existing software. This book attempts to give the reader a gentle introduction to graphical modeling using R and the main features of some of these packages. In addition, the bookprovides examples of how more advanced aspects of graphical modeling can be represented and handled within R. Topics covered in the seven chapters include graphical models for contingency tables, Gaussian and mixed graphical models, Bayesian networks and modeling high dimensional data.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 192 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -As cognitive models of behavior continue to evolve, the mechanics of cognitive exceptionality, with its range of individual variations in abilities and performance, remains a challenge to psychology. Reaching beyond the standard view of exceptional cognition equaling superior intelligence, the Handbook of Individual Differences in Cognition examines the latest findings from psychobiology, cognitive psychology, and neuroscience, for a comprehensive state-of-the-art volume.Breaking down cognition in terms of attentional mechanisms, working memory, and higher-order processing, contributors discuss general models of cognition and personality. Chapter authors build on this foundation as they revisit current theory in such areas as processing effort and general arousal and examine emerging methods in individual differences research, including new data on the role of brain plasticity in cognitive function. The possibility of a unified theory of individual differences in cognitive ability and the extent to which these variables may account for real-world competencies are emphasized, and commentary chapters offer suggestions for further research priorities.Coverage highlights include:The relationship between cognition and temperamental traits.The development of autobiographical memory.Anxiety and attentional control.The neurophysiology of gender differences in cognitive ability.Intelligence and cognitive control.Individual differences in dual task coordination.The effects of subclinical depression on attention, memory, and reasoning.Mood as a shaper of information.Researchers, clinicians, and graduate students in psychology and cognitive sciences, including clinical psychology and neuropsychology, personality and social psychology, neuroscience, and education, will find the Handbook of Individual Differences in Cognition an expert guide to the field as it currently stands and to its agenda for the future.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 520 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book contains the proceedings of an interna tional symposium devoted to Modeling and Analysis of Defense Processes in the context of land/air warfare. It was sponsored by Panel VII (on Defense Applications of Operational Research) of NATO's Defense Research Group (DRG) and took place 27-29 July 1982 at NATO headquarters in Brussels. Except perhaps for the Theater-Level Gaming and Analysis Workshop, sponsored by the Office of united 1 states Naval Research in 1977 , this symposium was the first international scientific meeting on Operations Research/Systems Analysis in the area of land/air war fare since the conference on Modeling Land Battle Systems 2 for Military Planning sponsored by NATO's Special Pro gramme Panel on Systems Science in 1974. That conference dealt primarily with modeling small unit (company, bat talion) engagements and, to a lesser extent, large unit (corps, theater) campaigns with principal emphasis on attrition processes and movement in combat. It was considered as rather successful in that it revealed the state-of-the art around 1972 and identified problem areas and promising approaches for future developments. lWith regard to foreign attendance, this wo- shop was largely limited to participants from the United Kingdom and the Federal Republic of Germany (see L.J. Low: Theater-Level Gaming and Analysis Workshop for Force Planning, Vol II-Summary, Discus sion of Issues and Requirements for Research, SRI Report, May, 1981).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 932 pp. Englisch.

Buch. Zustand: Neu. Neuware -Metadata standards in today¿s ICT sector are proliferating at unprecedented levels, while automated information management systems collect and process exponentially increasing quantities of data. With interoperability and knowledge exchange identified as a core challenge in the sector, this book examines the role ontology engineering can play in providing solutions to the problems of information interoperability and linked data. At the same time as introducing basic concepts of ontology engineering, the book discusses methodological approaches to formal representation of data and information models, thus facilitating information interoperability between heterogeneous, complex and distributed communication systems. In doing so, the text advocates the advantages of using ontology engineering in telecommunications systems. In addition, it offers a wealth of guidance and best-practice techniques for instances in which ontology engineering is applied in cloud services, computer networks and management systems.Engineering and computer science professionals (infrastructure architects, software developers, service designers, infrastructure operators, engineers, etc.) are today confronted as never before with the challenge of convergence in software solutions and technology. This book will help them respond creatively to what is sure to be a period of rapid development.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The present volume contains the edited transcript of a Totts Gap Colloquium held May 19-21, 1980 sponsored by the Muscular Dystrophy Association. The aim of the colloquium was to bring into focus data relating to cell membranes that might contribute to understanding the pathogenic mechanism of Duchenne muscular dystrophy. A major impediment to progress in understanding the patho genesis of muscular dystrophy has been the failure, so far, to identify the basic genetic defect. Pending the identification of the genetic lesion in Duchenne dystrophy and, in view of scattered but persistent indications of a basic membrane disturbance, it seemed worthwhile to explore in open dialogue the current state of knowledge of membrane morphology and chemistry with an eye to possible leads for further investigation. The participants, drawn from a variety of interested disciplines, attempted to synthesize and reconcile their findings and to identify crucial areas of ignorance in need of exploration. For the most part they avoided specialized jargon and spoke in a language that could be understood by the rest of the group. Apart from providing a review of widely varying approaches to the study of the composition and behavior of cell membranes, the discussions brought together current think~g on strategies and approaches to the study of the pathogenesis of muscular dystrophy. Already the personal contacts made at the colloquium have led to new inter-institutional collabora tive investigations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Buch. Zustand: Neu. Neuware -A number of food engineering operations, in which heat is not used as a preserving factor, have been employed and are applied for preparation (cleaning, sorting, etc.), conversion (milling, agglomeration, etc.) or preservation (irradiation, high pressure processing, pulsed electric fields, etc.) purposes in the food industry. This book presents a comprehensive treatise of all normally used food engineering operations that are carried out at room (or ambient) conditions, whether they are aimed at producing microbiologically safe foods with minimum alteration to sensory and nutritive properties, or they constitute routine preparative or transformation operations. The book is written for both undergraduate and graduate students, as well as for educators and practicing food process engineers. It reviews theoretical concepts, analyzes their use in operating variables of equipment, and discusses in detail different applications in diverse food processes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 376 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The nutritional quality of a protein depends on the proportion of its amino acids-especially the essential amino acids-their physio logical availability, and the specific requirements of the consumer. Availability varies and depends on protein source, interaction with other dietary components, and the consumer's age and physiological state. In many foods, especially those from plants, low levels of various essential amino acids limits their nutritive value. This is particularly important for cereals (which may be inadequate in the essential amino acids isoleucine, lysine, threonine, and tryto phan) and legumes (which are often poor sources of methionine). Moreover, these commodities are principle sources of protein for much of the earth's rapidly growing population. At the current annual growth rate of about 2 percent, the world population of about 4 billion will increase to 6.5 billion by the year 2000 and to 17 billion by the year 2050. Five hundred milliQn people are presently estimated to suffer protein malnutrition, with about fifteen thousand daily deaths. The ratio of malnourished to adequately nourished will almost surely increase. For these reasons, and especially in view of the limited availability of high quality (largely animal) protein to feed present and future populations, improvement of food and feed quality is especially important.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 900 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Research over the last decade has brought about the development of high-performance systems such as powerful workstations, sophisticated computer graphics, and multimedia systems such as real-time video and speech recognition. A significant change in the attitude of users is the desire to have access to this computation at any location without the need to be connected to the wired power source. This has resulted in the explosive growth of research and development in the area of wireless computing over the last five years.Technologies for Wireless Computing deals with several key technologies required for wireless computing. The topics covered include reliable wireless protocols, portable terminal design considerations, video coding, RF circuit design issues and tools, display technology, energy-efficient applications, specific and programmable design techniques, energy efficiency metrics, low-voltage process technology and circuit design considerations, and CAD tools for low-power design at the behavior, logic and physical design level.Technologies for Wireless Computing is an edited volume of original research comprising invited contributions by leading researchers. This research work has also been published as a special issue of the Journal of VLSI Signal Processing Systems (Volume 13, Numbers 2 & 3).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Pest Management Programs for Deciduous Tree Fruits and Nuts attempts to present the current status of pest management programs in orchard ecosystems. The book is a collection of papers from a symposium convened on the subject for the 1977 National Meeting of the Entomological Society of America and invitational papers on commodities not covered during the symposium. In recent years, books have appeared on 'integrated pest management (IPM)'; however, most of these have concentrated on field crop IPM with an occasional chapter on fruits. No publication presently exists which brings together information on the pest management programs currently being conducted on the major nut crops, almonds, pecans and walnuts. Because it is the first treatment for almonds and walnuts, the authors of these chapters have attempted not only to present the current IPM technology but the historical data which led to the contemporary programs. Two chapters appear on pecan IPM. The first concentrates on the development of a management program for the pecan weevil, the key arthropod pest of pecans, while the second discusses the implementation of pilot pecan IPM programs in two southeastern states. The latter chapter illustrates that even with a limited data bank, the pesticide load in pecan orchards can be reduced by the adoption of the IPM approach to pest control.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 272 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Substantial progress has been made during the past three decades in the development of a variety of chemical means to control insect pests. A large number of highly effective insecticides have been developed, and many of them have contributed to a great extent to increasing agricultural productivity and eradicating diseases transmitted by vectors. However, contamination of our environment caused by various pesticides has become a serious problem, and various attempts have been made to develop newer methods of con trolling insect pests. One of the approaches is to develop newer insecticides which cause less contamination of the environment without losing their insecticidal potencies. Another approach, among other things, is to utilize pheromones to control certain species of insects. No matter what approach one may choose, it is imperative to understand the mechanism of action of pesticides for efficient development and utilization of these chemicals. One important feature common to most insecticides and pheromones is their inter action with the nervous system which is the main target site. Thus the mechanisms of action of these chemicals on the nervous system represent one of the most critical aspects in pesticide toxicology. In comparison to the chemical and biochemical studies dealing with the metabolism of various pesticides, the study of neurotoxicology has lagged behind to a considerable extent for various reasons. Technical complications involved in neuroto- co logical experiments appear to be one of the contributing factors.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 320 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The subject matter of this volume was the basis for a confer ence held in Philadelphia in June, 1981, and is an important one in the contemporary area of how the host interacts with micro organisms. In conception, it grew out of a graduate course entitled, 'The Infectious Process,' which has been taught in the Department of Microbiology and Immunology at Temple University School of Medicine during the past twelve years. This course has explored the broad areas of mechanisms of microbial pathogenesis and host resistance by in-depth consideration of selected models of experimental infection and immunity, as well as the clinical literature. It is noteworthy that there is no adequate text for this material, as the subject matter naturally crosses a wide spectrum of traditional disciplinary lines, encompassing topics as diverse as the mechanisms of action of bacterial toxins, the role of complement and antibody in phagocytosis, and the importance of cross-reacting bacterial polysaccharide antigens in vaccine development. A major portion of the course has always considered 'cellular immunity' as it applies to host defenses to intracellular pathogens. It is in this area that the necessity for amalgamation of information from different disciplines is most evident, for one must be intimately concerned with the interactions between the microbe and the phagocyte, both before and after specific immune recognition.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 556 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Fluidized beds have gained prominence in many process in dustries (including chemicals, petroleum, metallurgy, food and pharmaceuticals) as a means of bringing particulate solids into contact with gases and/or liquids. Many fluidized bed operations are physical in nature (e.g. drying, coating, classification, granulation, and rapid heat transfer as in quenching or annealing). Other operations involve chemical reactions including the cata lytic cracking of hydrocarbons, the manufacture of acry10nitrite and phthalic anhydride, the roasting of metallurgical ores, and the regeneration of spent catalysts. In recent years fluidized beds have been of special interest because of their potential as the central component in new processes for utilizing coal as a source of energy, notably in coal combustion and gasification processes. The fluidized bed offers a number of advantages over most other methods of contacting, in particular high rates of heat transfer, temperature uniformity and solids mobility. Among the disadvantages are particle losses by entrainment, attrition of solids, limited reactor efficiency due to gas bypassing and gas and solids backmixing, and difficulties in design and scale-up due to the complexity of fluidized beds. The International Fluidization Conference held in Henniker, New Hampshire, U.S.A. from 3-8 August 1980 was the fifth inter national congress devoted to the entire field of fluidization.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 624 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This text originated as a lecture delivered November 20, 1984, at Queen's University, in the undergraduate colloquim series established to honor Professors A. J. Coleman and H. W. Ellis and to acknow ledge their long lasting interest in the quality of teaching under graduate students. In another colloquim lecture, my colleague Morris Orzech, who had consulted the latest edition of the Guilllless Book oj Records, remainded me very gently that the most 'innumerate' people of the world are of a certain tribe in Mato Grosso, Brazil. They do not even have a word to express the number 'two' or the concept of plurality. 'Yes Morris, I'm from Brazil, but my book will contain numbers different from 'one.' ' He added that the most boring 800-page book is by two Japanese mathematicians (whom I'll not name), and consists of about 16 million digits of the number 11. 'I assure you Morris, that in spite of the beauty of the apparent randomness of the decimal digits of 11, I'll be sure that my text will include also some words.' Acknowledgment. The manuscript of this book was prepared on the word processor by Linda Nuttall. I wish to express my appreciation for the great care, speed, and competence of her work. 504 pp. Englisch.
