Buch. Zustand: Neu. Neuware - 'Improving the performance of the power amplifier is the most pressing problem facing designers of modern radio-frequency (RF) transceivers. Linearity and power efficiency of the transmit path are of utmost importance, and the power amplifier has proven to be the bottleneck for both. High linearity enables transmission at the highest data rates for a given channel bandwidth, and power efficiency prolongs battery lifetime in portable units and reduces heat dissipation in high-power transmitters. Cartesian feedback is a power amplifier linearization technique that acts to soften the tradeoff between power efficiency and linearity in power amplifiers. Despite its compelling, fundamental advantages, the technique has not enjoyed widespread acceptance because of certain implementation difficulties. Feedback Linearization of RF Power Amplifiers introduces new techniques for overcoming the challenges faced by the designer of a Cartesian feedback system. The theory of the new techniques are described and analyzed in detail. The book culminates with the results of the first known fully integrated Cartesian feedback power amplifier system, whose design was enabled by the techniques described. Feedback Linearization of RF Power Amplifiers is a valuable reference work for engineers in the telecommunications industry, industry researchers, academic researchers. '.

Buch. Zustand: Neu. Neuware - Palmprint Authentication is the first book to provide a comprehensive introduction to palmprint technologies. It reveals automatic biometric techniques for personal identification using palmprint, from the approach based on offline palmprint images, to the current state-of-the-art algorithm using online palmprint images. Palmprint Authentication provides the reader with a basic concept of Palmprint Authentication. It also includes an in-depth discussion of Palmprint Authentication technologies, a detailed description of Palmprint Authentication systems, and an up-to-date coverage of how these issues are developed. This book is suitable for different levels of readers: those who want to learn more about palmprint technology, and those who wish to understand, participate, and/or develop a palmprint authentication system. Palmprint Authentication is effectively a handbook for biometric research and development. Graduate students and researchers in computer science, electrical engineering, systems science, and information technology will all find it uniquely useful, not only as a reference book, but also as a text book. Researchers and practitioners in industry, and R&D laboratories working in the fields of security system design, biometrics, immigration, law enforcement, control, and pattern recognition will also benefit from this volume.

Buch. Zustand: Neu. Neuware - This book is of interest to mathematicians, geologists, engineers and, in general, researchers and post graduate students involved in spline function theory, surface fitting problems or variational methods. From reviews: The book is well organized, and the English is very good. I recommend the book to researchers in approximation theory, and to anyone interested in bivariate data fitting.' (L.L. Schumaker, Mathematical Reviews, 2005).

Buch. Zustand: Neu. Neuware - An Introduction to Surface-Micromachining provides for the first time a unified view of surface-micromachining. Building up from the basic building block of microfabrication techniques, to the general surface-micromachining design, it will finish with the theory and design of concrete components. An Introduction to Surface-Micromachining connects the manufacturing process, microscale phenomena, and design data to physical form and function. This book will be of interest to mechanical engineers looking to scale down into micromachining and microelectronics designers looking to move horizontally to micromachining.

Buch. Zustand: Neu. Neuware - Automatic Quantum Computer Programming provides an introduction to quantum computing for non-physicists, as well as an introduction to genetic programming for non-computer-scientists. The book explores several ways in which genetic programming can support automatic quantum computer programming and presents detailed descriptions of specific techniques, along with several examples of their human-competitive performance on specific problems. Source code for the author's QGAME quantum computer simulator is included as an appendix, and pointers to additional online resources furnish the reader with an array of tools for automatic quantum computer programming.

Buch. Zustand: Neu. Neuware - The 21st century will witness the unprecedented marketing of therapeutic drugs developed from cannabinoids and the endocannabinoid system. Cannabinoids is a timely volume, which represents a comprehensive review of the most important issues in cannabinoid research as well as those of most likely therapeutic relevance. For the first time, the multi-faceted aspects of cannabinoid chemistry, biology and medicine are presented in one volume. Key topics of discussion: -major families of phytocannabinoids; -pharmacological activity of phytocannabinoids; -interactions of phytocannabinoids with their proposed molecular target; -components of the endocannabinoid system; -molecular mechanisms of the endocannabinoid system; -Physiological and pathological role of endocannabinoids; -industrial applications of studies on the cannabinoids; -therapeutic uses of agonists and antagonists of cannabinoids receptors. This book is a must for graduate and pre- and post-doctoral students in disciplines ranging from organic and natural product chemistry, pharmacology, biochemistry and medicine.

Buch. Zustand: Neu. Neuware - Community Operational Research: OR and Systems Thinking for Community Development sets out the current concerns of Community Operational Research (Community OR for short) and explores new possibilities for its continued development. Leading Community OR writers, with international reputations in operational research and systems thinking, have contributed chapters that illuminate different aspects of Community OR theory and practice. There is a focus on the value of systems approaches, and other significant perspectives are also represented. The result is a rich mix of theories, methodologies and case studies that will be a significant resource for both practitioners and academics engaged in community development.

Buch. Zustand: Neu. Neuware - Information Systems Research: Relevant Theory and Informed Practice comprises the edited proceedings of the WG8.2 conference, 'Relevant Theory and Informed Practice: Looking Forward from a 20-Year Perspective on IS Research,' which was sponsored by IFIP and held in Manchester, England, in July 2004. The conference attracted a record number of high-quality manuscripts, all of which were subjected to a rigorous reviewing process in which four to eight track chairs, associate editors, and reviewers thoughtfully scrutinized papers by the highly regarded as well as the newcomers. No person or idea was considered sacrosanct and no paper made it through this process unscathed. All authors were asked to revise the accepted papers, some more than once; thus, good papers got better. With only 29 percent of the papers accepted, these proceedings are significantly more selective than is typical of many conference proceedings. This volume is organized in 7 sections, with 33 full research papers providing panoramic views and reflections on the Information Systems (IS) discipline followed by papers featuring critical interpretive studies, action research, theoretical perspectives on IS research, and the methods and politics of IS development. Also included are 6 panel descriptions and a new category of 'bright idea' position papers, 11 in all, wherein main points are summarized in a pithy and provocative fashion.
