经典OFDM教材,原书第二版 Multi-Carrier Digital Communications Theory and Applications of OFDM, Second Edition Multi-carrier modulation, Orthogonal Frequency Division Multiplexing (OFDM) particularly, has been successfully applied to a wide variety of digital communications applications over the past several years. OFDM has been chosen as the physical layer standard for a variety of important systems and its implementation techniques continue to evolve rapidly. This book is a valuable summary of the technology, providing an understanding of new advances as well as the present core technology. A unified presentation of OFDM performance and implementation over a wide variety of channels, including both wireline and wireless systems, is made. This will prove valuable both to developers of such systems and to researchers and graduate students involved in analysis of digital communications. In the interest of brevity, the authors have minimized treatment of more general communication issues. There exist many excellent texts on communication theory and technology. Only brief summaries of topics not specific to multi-carrier modulation are presented in this book where essential. As a background, it is assumed that the reader has a clear knowledge of basic fundamentals of digital communications. Highlights of the Second Edition During the past few years since the publication of the first edition of this text, the technology and application of OFDM have continued their rapid pace of advancement. As a result, it became clear that a new edition of the text would be highly desirable. The new edition provides the opportunity to make those corrections and clarifications whose need became apparent from continued discussions with many readers. However, the main purpose is to introduce new topics that have come to the forefront during the past few years, and to amplify the treatment of other subject matter. Because of the particularly rapid development of wireless systems employin

Density Functional Theory: A Practical Introduction offers a concise, easy-to-follow introduction to the key concepts and practical applications of DFT, focusing on plane-wave DFT. The authors have many years of experience introducing DFT to students from a variety of backgrounds. The book therefore offers several features that have proven to be helpful in enabling students to master the subject, including: Problem sets in each chapter that give readers the opportunity to test their knowledge by performing their own calculations Worked examples that demonstrate how DFT calculations are used to solve real-world problems Further readings listed in each chapter enabling readers to investigate specific topics in greater depth

并联机构外文资料,parallel mechanisms (PMs) have attracted a lot of attention from the academic and industrial communities. Compared with the more commonly used serial robots, the parallel one has attractive advantages in accuracy, rigidity, capacity, and load-to-weight ratio. The PMs have been and are being used in a wide variety of applications such as motion simulators, parallel manipulators, nanomanipulators, and micro-manipulators. In recent years, the research and application have evolved from general six-DOF PMs to lower-mobility PMs. The essential reason is that lower-mobility PMs have similar applications to general six-DOF PMs, while they are much simpler in structure and cheaper in cost. The research of lower-mobility PMs has become new hot point. A great deal of research on lowermobility PM has been carried out all over the world, and a large number of new mechanisms, such as Delta, Tricept, and medical robots, have been built for various applications.

最优传输理论的详细数学基础“When I was first approached for the 2005 edition of the Saint-Flour Probability Summer School, I was intrigued, flattered and scared.1 Apart from the challenge posed by the teaching of a rather analytical subject to a probabilistic audience, there was the danger of producing a remake of my recent book Topics in Optimal Transportation. However, I gradually realized that I was being offered a unique opportunity to rewrite the whole theory from a different perspective, with alternative proofs and a different focus, and a more probabilistic presentation; plus the incorporation of recent progress. Among the most striking of these recent advances, there was the rising awareness that John Mather’s minimal measures had a lot to do with optimal transport, and that both theories could actually be embedded in a single framework. There was also the discovery that optimal transport could provide a robust synthetic approach to Ricci curvature bounds. These links with dynamical systems on one hand, differential geometry on the other hand, were only briefly alluded to in my first book; here on the contrary they will be at the basis of the presentation. To summarize: more probability, more geometry, and more dynamical systems. Of course there cannot be more of everything, so in some sense there is less analysis and less physics, and also there are fewer digressions”
