Buch. Zustand: Neu. Neuware - Perspectives in Spread Spectrum brings together studies and recent work on six exciting topics from the spread spectrum arts. The book gives a wide, collective view of trends, ideas, and techniques in the spread spectrum discipline, due to the authors' extensive work on spread spectrum techniques and applications from different vantage points. The inexorable march of electronics towards ever faster, ever smaller, and ever more powerful electronic and optical circuitry has wrought, and will continue to enable, profound changes in the spread spectrum arts, by allowing increasingly complex signalling waveforms and statistical tests to be implemented as the theory beyond spread spectrum continues to evolve. Perspectives in Spread Spectrum is divided into six chapters. The first chapter deals with sequence spreading design. There is not a single metric for design of spreading sequences; rather, the design is ideally tailored to the specific scenario of usage. This chapter delves into recent and very promising synthesis work. The second chapter deals with OFDM techniques. As channels become wider and trans-channel fading (or jamming) becomes frequency selective across the band, OFDM techniques may provide a powerful alternative design perspective. The third chapter is a generalization of the venerable Walsh functions. A new modulation scheme, Geometric Harmonic Modulation, GHM for short, is reviewed and characterized as a form of OFDM. From GHM, a further generalization of the Walsh functions is derived for non-binary signalling. The fourth chapter is concerned with some new and exciting results regarding the follower jammer paradigm. A counter-countermeasure technique is reviewed, notable for its counterintuitive characteristic which can be understood from a simple yet elegant game framework. The fifth chapter recounts some results pertaining to random coding for an optical spread spectrum link. The technique is basedon laser speckle statistics and uses a coherent array of spatial light modulators at the transmitter but allows the receiver to be realized as a spatially distributed radiometric and therefore incoherent structure. The sixth and final chapter looks at an important and interesting application of spread spectrum to accurately locate a wideband, bent pipe , satellite transponder. It is, in a strong sense, an inverted GPS technique. Perspectives in Spread Spectrum serves as an excellent reference and source of ideas for further research, and may be used as a text for advanced courses on the topic.…

Buch. Zustand: Neu. Neuware - Adaptive Resonance Theory Microchips describes circuit strategies resulting in efficient and functional adaptive resonance theory (ART) hardware systems. While ART algorithms have been developed in software by their creators, this is the first book that addresses efficient VLSI design of ART systems. All systems described in the book have been designed and fabricated (or are nearing completion) as VLSI microchips in anticipation of the impending proliferation of ART applications to autonomous intelligent systems. To accommodate these systems, the book not only provides circuit design techniques, but also validates them through experimental measurements. The book also includes a chapter tutorially describing four ART architectures (ART1, ARTMAP, Fuzzy-ART and Fuzzy-ARTMAP) while providing easily understandable MATLAB code examples to implement these four algorithms in software. In addition, an entire chapter is devoted to other potential applications for real-time data clustering and category learning.…

Buch. Zustand: Neu. Neuware - Policy and outcome studies represent a new area of research in oncology. Understanding the factors that affect quality of life, costs of care, patterns of care, and outcomes in oncology is important to providing comprehensive care. Health services is meant to be both a productive area of research as well as a discipline that improves patient decision making. In sum, Cancer Policy highlights some of the important areas of health services research in oncology.…

Buch. Zustand: Neu. Neuware - There is broad interest in feature extraction, construction, and selection among practitioners from statistics, pattern recognition, and data mining to machine learning. Data preprocessing is an essential step in the knowledge discovery process for real-world applications. This book compiles contributions from many leading and active researchers in this growing field and paints a picture of the state-of-art techniques that can boost the capabilities of many existing data mining tools. The objective of this collection is to increase the awareness of the data mining community about the research of feature extraction, construction and selection, which are currently conducted mainly in isolation. This book is part of our endeavor to produce a contemporary overview of modern solutions, to create synergy among these seemingly different branches, and to pave the way for developing meta-systems and novel approaches. Even with today's advanced computer technologies, discovering knowledge from data can still be fiendishly hard due to the characteristics of the computer generated data. Feature extraction, construction and selection are a set of techniques that transform and simplify data so as to make data mining tasks easier. Feature construction and selection can be viewed as two sides of the representation problem.…

Buch. Zustand: Neu. Neuware - Today the Scottish electronics industry employs 40,000 people directly and a further 30,000 in the supply infrastructure. There are now more than 550 electronic manufacturing and supplier companies in ' Silicon Glen'. In terms of the contribution to the economy, electronics is by far the most valuable industry. Its value in 1996 was approximately £ 10billion and accounted for more than half of Scotland's exports. The major product groupings within the industry include: - PCs, laptops and workstations - Disk drives, cable harnessing - Printers, keyboards and peripherals - Semiconductor devices and PCBs - TV, VCRs, CDs, stereos and other consumer electronics - Cellular phones and telecommunications products - A TMs and funds transfer systems - Networking and security systems - Navigation and sonar systems - Microwave products - Power supplies - Software and compilers Many of these companies are multi-national OEMs, who came to Scotland as inward investing companies. Early inward investing companies were from USA, followed by companies from Japan, and more recently from Taiwan and Korea. An important segment of the industry is involved in the manufacture of computers, including IBM, Compaq, Digital and Sun. In fact approximately 40% of the PCs sold in Europe are built in Scotland. With five of the world's top eight computer manufacturers locating a manufacturing base in Scotland there has been an attraction for foreign companies keen to provide service for these multinationals. In 1995/96 the supply base output was worth £1. …

Buch. Zustand: Neu. Neuware - Infection is a major cause of morbidity and mortality in patients with neoplastic disease because of compromised host defenses. These defects result in an increased risk of infection and its complications. The nature of the underlying malignancy, the immunodeficiencies associated with it, and the treatments directed against it are all important determinants of infection. In recent years, the introduction of more intensive chemotherapeutic regimes and the widespread use of bone marrow and peripheral stem cell transplantation have changed the pattern of infection in many patients. Furthermore, the increasing use of central venous access devices and antimicrobial prophylaxis has changed the epidemiology of infection in these patients as well. The goal of this volume in the Cancer Treatment and Research series is to emphasize that while the management of infection in cancer patients is common, it is constantly changing. With the increasing complexity of these patients, optimal management requires a multidisciplinary approach. Ultimately, it is hoped that this book will assist clinicians in the diagnosis, management, and prevention of infection in order to optimize care for patients with cancer.…
