Taschenbuch. Zustand: Neu. Neuware - Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework.The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used remain simple and most analyses are graphical rather than algebraic. The text will therefore appeal to students, scientists and policy makers in the field of ecology, fisheries, pollution studies and water management, and also to theoreticans who will benefit from the many real-world examples of topics such as predation and competition theory, bifurcation analysis and catastrophe theory. Perhaps most importantly, the book is a remarkable example of how large field experiments and simple models can catalyze our insight into complex ecosystems.Marten Scheffer wrote this book while at the Institute of Inland Water Management and Waste Treatment, RIZA, Lelystad, The Netherlands. He is currently at the Department of Water Quality Management and Aquatic Ecology of the Wageningen Agricultural University.Reviews`Much rarer are textbooks that so succinctly sum up the state-of-the-art knowledge about a subject that they become instant `bibles'. This book is one of these. It is probably one of the best biological textbooks I have read. Scheffer masterfully pulls all this information together under one cover and presents a coherent account, which will serve as a benchmark for the subject. The reader will not gain any great insight into the breeding biology of pike from this book, nor learn much about dragonflies or newts. They will, however, come to understand the essential nature of shallow lakes or, as the author puts it, `how shallow lakes work'. Overall, this book will be of great interest to practical and theoretical ecologists, students and managers in all fields of biology. All freshwater ecologists should certainly read it.' Simon Harrison in Journal of Ecology, 86 `The book by Scheffer can be seen as a milestone in the recognition of shallow lakes as a research topic in its own right. Scheffer uses three approaches concurrently to unravel the functioning of shallow lakes: 1) statistical analysis of large datasets from a variety of lakes; 2) simple abstract models made up of a few non-linear ordinary differential equations, which he calls `mini-models'; and 3) logical reasoning based on a mixture of results from fieldwork, experiments and models. What is new is that Scheffer links mathematics very nicely with what one feels is a correct description of the functioning of a shallow lake. Employing logical reasoning, Scheffer combines all these sources of knowledge into a general, coherent picture of the functioning of a shallow lake.' Wolf Mooij in Aquatic Ecology, 32.…

Buch. Zustand: Neu. Neuware - Every day we experience the annoyance of having to queue. The phenomenon is becoming more prevalent in our increasingly congested and urbanised society. Not only the visible queues in traffic jams, airport check in desks and supermarkets, but the more common invisible queues caused by voice calls and data packets in optical and wireless channels. Queues cost us time, money and resources; so what is the solution to our greater demand for services than there are facilities Queuing control plays a crucial role in manufacturing and communication networks around the world. This pioneering approach, using fuzzy control to solve queuing control problems, determines explicit solutions to various types of control in queuing systems. The bulk of results have been developed over the past decade and are presented here together for the first time. 21 detailed case studies demonstrate an efficient departure from classical techniques.Unique work creating a new Research and Development topic.Multidisciplinary approach that will benefit researchers and students throughout the fields of artificial intelligence, operations research, optimal control, Internet techniques, communications and traffic control industries.Equipped with an extensive bibliography for easy reference and scope for further study. Existing practical problems, especially those that are unresponsive to conventional control techniques, are solved with the introduction of this novel approach. A systematic framework of the 'fuzzy control of queuing networks' is developed through each individual case.…

Buch. Zustand: Neu. Neuware - Medical imaging has been transformed over the past 30 years by the advent of computerized tomography (CT), magnetic resonance imaging (MRI), and various advances in x-ray and ultrasonic techniques. An enabling force behind this progress has been the (so far) exponentially increasing power of computers, which has made it practical to explore fundamentally new approaches. In particular, what our group terms 'model-based' modalities-which produce tissue property images from data using nonlinear, iterative numerical modeling techniques-have become increasingly feasible.Alternative Breast Imaging: Four Model-Based Approaches explores our research on four such modalities, particularly with regard to imaging of the breast: (1) MR elastography (MRE), (2) electrical impedance spectroscopy (EIS), (3) microwave imaging spectroscopy (MIS), and (4) near infrared spectroscopic imaging (NIS). Chapter 1 introduces the present state of breast imaging and discusses how our alternative modalities can contribute to the field. Chapter 2 looks at the computational common ground shared by all four modalities. Chapters 2 through 10 are devoted to the four modalities, with each modality being discussed first in a theory chapter and then in an implementation-and-results chapter. The eleventh and final chapter discusses statistical methods for image analysis in the context of these four alternative imaging modalities.Imaging for the detection of breast cancer is a particularly interesting and relevant application of the four imaging modalities discussed in this book. Breast cancer is an extremely common health problem for women; the National Cancer Institute estimates that one in eight US women will develop breast cancer at least once in her lifetime. Yet the efficacy of the standard (and notoriously uncomfortable) early-detection test, the x-ray mammogram, has been disputed of late, especially for younger women. Conditions are thus ripe for the development of affordable techniques that replace or complement mammography. The breast is both anatomically accessible and small enough that the computing power required to model it, is affordable. …

Buch. Zustand: Neu. Neuware - Wolfgang Glatzer Johann Wolfgang Goethe-Universitiit Franlifurt am Main, Germany ABSTRACT Challenges for the quality of life in the contemporary world were the focus of the Fifth International Quality of Life-Conference in Frankfurt am Main in the year 2003, hosted and organized by the Interna tional Society for Quality of Life Studies. The first part of this introductory article is concerned with a general assessment of contemporary quality of life research. At present, the concept of quality of life is a kind of umbrella which keeps together a reasonable number of international social scientists who have similar research interests. The second part of the introduction describes the topics of this book: The five chapters are concerned with the societal goal discussion on quality of life, the scientific monitoring of quality of life, the economic challenges for quality of life, its cultural challenges, and finally the options and restrictions for improving quality of life. Altogether, the contributions are related to present interna tional investigations and discussions of basic questions of quality of life.

Buch. Zustand: Neu. Neuware - The growing interest in health risks associated with toxigenic fungi and related mycotoxins has led to the development of a number of research projects during the past decade in several European countries and a great deal of information has been produced on the natural occurrence of mycotoxins in plants, foods and feeds. The differences in environmental conditions (temperature, light, rainfall etc. ) and in exposed cultivated plants (type of cereals, cultivars etc. ) in the distinct European countries have significantly influenced the distribution of specific toxigenic fungi and related mycotoxicological problems. In addition, biogeographically structured lineages within some important toxigenic fungi have been recently discovered, of reproductive isolation. Transglobal showing a long evolutionary history transposition of plant products seems to have significantly contributed to the spreading of toxigenic species and lineages worldwide. Therefore, the migration of agriculturally important toxigenic fungi generated by trade exchanges may represent a major source of inoculum for new plant diseases in Europe and for a wider genetic diversity of local populations. It was our goal to provide the reader with an update of researches and surveys on the natural occurrence of toxigenic fungi and mycotoxins performed at a European level during the last 5-10 years. The editors are extremely grateful to the EU-COST-835 'Agriculturally important toxigenic fungi' for the financial support that allowed a number of European scientists to meet several times over the past five years to collaborate and exchange information about research advances on toxigenic fungi and mycotoxins.…

Buch. Zustand: Neu. Neuware - There has continuously been a massive growth of Internet traffic for these years despite the 'bubble burst' in year 2000. As the telecom market is gradually picking up, it would be a consensus in telecom and data-com industries that the CAPEX (Capital Expenditures) to rebuild the network infrastructure to cope with this traffic growth would be imminent, while the OPEX (Operational Expenditures) has to be within a tight constraint. Therefore, the newly built 2r^-century network has to fully evolve from voice-oriented legacy networks, not only by increasing the transmission capacity of WDM links but also by introducing switching technologies in optical domain to provide full-connectivity to support a wide variety of services. This book stems from the technical contributions presented at the Optical Networks and Technology Conference (OpNeTec), inaugurated this year 2004 in Pisa, Italy, and collects innovations of optical network technologies toward the 2V^ century network. High-quality recent research results on optical networks and related technologies are presented, including IP over WDM integration, burst and packet switchings, control and managements, operation, metro- and access networks, and components and devices in the perspective of network application. An effort has been made throughout the conference, hopefully reflected at least partially in this book, to bring together researchers, scientists, and engineers working both academia and industries to discuss the relative impact of networks on technologies and vice versa, with a vision of the future.…

Buch. Zustand: Neu. Neuware - The fast detection of explosives from the vapor phase would be one way to enhance the protection of society against terrorist attacks. Up to now the problem of detection of explosives, especially the location of explosives whether at large areas e. g. station halls, theaters or hidden in cars, aircraft cargo, baggage or explosives hidden in crowds e. g. suicide bombers or bombs in bags has not been solved. Smelling of explosives like dogs do seems to be a valuable tool for a security chain. In general different strategies can be adopt to the basic problem of explosive detection: - bulk detection - vapor detection Normally meetings cover both aspects and applications of the detection. Even though both methods might fulfill special aspects of a general security chain the underlying scientific questions differ strongly. Because of that the discussions of the scientists and practitioners from the different main directions are sometimes only less specific. Therefore the NATO Advisory Panel in Security-Related Civil Science and Technology proposed a small series of NATO ARW's which focuses on the different scientific aspects of explosives detection methods. This book is based on material presented at the first NATO ARW of this series in Moscow which covered the topic: Vapor and trace detection of explosives. The second ARW was held in St. Petersburg and treated the topic Bulk detection methods. The third workshop was held in Warwick and focused on electronic noses which cover a somewhat different aspect of vapor detection. …

Buch. Zustand: Neu. Neuware - The Indian subcontinent is a vast land mass inhabited by over one billion people. Its rich and varied history is reflected by its numerous racial and ethnic groups and its distinct religious, cultural and social characteristics. Like many developing countries in Asia, it is passing through both demographic and epidemiological transitions whereby, at least in some parts, the diseases of severe poverty are being replaced by those of Westemisation; obesity, diabetes, and heart disease, for example. Indeed, as we move into the new millennium India has become a land of opposites; on the one hand there is still extensive poverty yet, on the other hand, some of the most remarkable developments in commerce and technology in Asia are taking place, notably in the fields of information technology and biotechnology. India has always fascinated human geneticists and a considerable amount of work has been done towards tracing the origins of its different ethnic groups. In the current excitement generated by the human genome project and the molecular and genetic approach to the study of human disease, there is little doubt that this field will develop and flourish in India in the future. Although so far there are limited data about genetic diseases in India, enough is known already to suggest that this will be an extremely fruitful area of research. …

Buch. Zustand: Neu. Neuware - In the quest for higher data density in information technology manipulation of magnetization by other means than magnetic fields has become an important challenge. This lead to a startling revival of the magnetoelectric effect, which characterizes induction of a polarization by a magnetic field or of a magnetization by an electric field. The magnetoelectric crosslink of material properties opens just those degrees of freedom which are needed for the mutual control of magnetic and electric states. The book gives a state-of-the-art review on magnetoelectrics research, classifies current research tendencies, and points out possible future trends. Novel compounds and growth techniques and new theoretical concepts for the understanding of magnetoelectric coupling phenomena are introduced. Highlights are the discovery of 'gigantic' magnetoelectric effects which are strong enough to trigger electric or magnetic phase transitions; the concept of magnetochirality; and development 'structural' magnetoelectric effects in artificial multiphase compounds. The book is addressed to condensed-matter physicists with a particular focus on experts in highly correlated systems.…

Taschenbuch. Zustand: Neu. Neuware - Nella pratica clinica, l'iniziale orientamento nel labirinto delle Pneumopatie Infiltrative Diffuse è dato sempre più spesso dalla Tomografia Computerizzata ad Alta Risoluzione (HRTC) che consente di formulare le prime ipotesi diagnostiche e di programmare gli accertamenti successivi. Gli Autori propongono di usare l'HRTC come 'filo d'Arianna' per districarsi nel dedalo di queste pneumopatie partendo dalla TX del paziente, si identifica il pattern predominante per mezzo di immagini di riferimento e poi, con l'aiuto di tavole sinottiche, si restringe il ventaglio delle ipotesi diagnostiche ad una o comunque ad un numero limitato di malattie. Ciascuna malattia è poi trattata in uno spazio dedicato che ne descrive da una parte l'epidemiologia ed i fattori di rischio, le modalità di presentazione e i dati funzionali e dall'altra gli aspetti anatomopatologici, radiologici e i reperti del lavaggio broncoalveolare per proporre infine l'iter diagnostico migliore. Nell'attuale panorama della letteratura scientifica, l'opera si distingue per diversi aspetti contenutistici e grafici: impostazione innovativa di stile fortemente didattico-approccio pratico alla diagnosi a partire dai pattern HRTC-tavole sinottiche illustrate per facilitare il collegamento dal pattern alla malattia, multidisciplinarità vera per compenetrazione delle competenze cliniche, anatomopatologiche e radiologiche all'interno della trattazione-ricca iconografia sia anatomopatologica che radiologicaLa pubblicazione si rivolge a pneumologi, anatomopatologi, radiologi ma anche al mondo vasto e articolato della medicina generale. Qualche malattia ha dei link verso il mondo oncologico, pediatrico, ematologico, della patologia infettiva, della terapia intensiva, della medicina del lavoro e della chirugia toracica.…
