Buch. Zustand: Neu. Neuware - The 'First International Conference on Traditional Chinese Medicine: Science, Regulation and Globalization' was held from August 30 to September 2, 2000 at the University of Maryland at College Park, Maryland. There were approximately 250 participants from the Peoples Republic of China, Taiwan, Hong Kong and the United States. This objective of this conference was to promote international collaboration for the modernization of Traditional Chinese herbal medicines (TCM) and their introduction into the global health care system. It was mainly sponsored by the Ministry of Science and Technology of the People's Republic of China and the NllI National Center for Complementary and Alternative Medicine (NCCAM). It was organized by Dr. William Tai, then director of the Institute of Global Chinese Affairs at the University of Maryland and Dr. Yuan Lin, president of Marco Polo Technologies, Bethesda, MD. This conference was conceived by Dr. Tai two years earlier recognizing that this was an appropriate time and also the unique location of the University of Maryland. Today, there is a growing recognition of the of alternative medicine in modem societies and the rapid loss of importance knowledge about traditional methods for the treatment of the multitude of human illnesses found throughout the world. TCM has been in common use in China for thousands of years; and many of its formulations are well defined.

Buch. Zustand: Neu. Neuware - The growth of telecommunications has been largely based on mobile and data services in the past 10 years and the growth will continue. For instance, it is forecasted that after 2005 the mobile traffic turnover in Europe will exceed that of fixed telephone traffic and the penetration of Internet access through mobile will exceed that of fixed access. It is expected that the new value added services will be Internet-based and the IP traffic will outweigh the amount of traditional ISDN based telephone traffic. The transition from the existing telecommunications services to mobile and Internet based ones will change the service infrastructure as well as the customer and service management structures. In wireless communications there are several new standards being developed and implemented to improve the data transmission rate over radio channels, to combine both voice, packet data and multimedia services in the terminals and to improve the service quality and usability. Narrow band packet radio standards such as General Packet Radio Service (GPRS) and i-Mode are already operative and broadband IMT-2000 standards, also called as Third Generation (3G) Mobile, have been developed in Japan, Europe and US. At the same time Wireless LAN and Bluetooth technologies mature and provide short-range data access to terminal devices. The emerging new technologies create opportunities not only to incumbent teleoperators but also to new network operators, IT companies and new service and content providers.

Buch. Zustand: Neu. Neuware - The broadband wireless communications field is growing at an explosive rate, stimulated by a host of important emerging applications ranging from 3G, 4G and wireless LAN. Wideband CDMA and CDMA2000 will be used for 3G. OFDM+CDMA might be a good choice for 4G, CDMA overlay will possibly be used for new-generation broadband wireless LAN. For system planners and designers, the projections of rapidly escalating demand for such wireless services present major challenges and meeting these challenges will require sustained technical innovation on many fronts. The text of this book has been developed through years of research by the author and his graduate students at the University of Hong Kong. The aim of this book is to provide a R&D perspective on the field of broadband wireless communications by describing the recent research developments in this area and also by identifying key directions in which further research is needed. As a background, I presume that the reader has a thorough understanding of digital communications and spread spectrum/CDMA. The book is arranged into 13 chapters. In chapter 1, some key specifications of 3G WCDMA are described and discussed. These techniques include channel coding, rate matching, modulation and spreading, power control, cell search, transmit diversity, soft-handoff, and so son. In Chapter 2, the coherent RAKE reception of Wideband CDMA signals with complex spreading is considered. A dedicated pilot channel, which is separate from data channels, is used for the purpose of channel estimation.

Buch. Zustand: Neu. Neuware - Faced with ever-increasing market demands, manufacturing industry is forced to seek innovation and technological breakthrough. This state-of-the-art text aims to integrate broad aspects of precision and production engineering to cope with rapid changes in market needs and technological developments as we enter the 21st century. It addresses basic theory, extensive research in advanced topics, industrial applications, and relevant surveys in related fields. Major subjects covered by this book include: Advanced manufacturing systems; Ultra-precision machining and micro machining; Nanotechnology for fabrication and measurement; Chemo-mechanical processes; Rapid prototyping technology; New materials and advanced processes; Computer-aided production engineering; Manufacturing process control; Planning. This volume contains the proceedings of the 10th International Conference on Precision Engineering (ICPE), which was held in July 2001, in Yokohama, Japan. ICPE is a well-established conference in the field of production and precision engineering, covering a wide range of topics for future-oriented manufacturing systems and processes; it is organized by the Japan Society for Precision Engineering (JSPE). This book can be used as a reference for graduate and undergraduate courses in precision and production engineering, and also for researchers and industrial engineers to capture current trends in this field.
