Buch. Zustand: Neu. Neuware - Information Systems: The e-Business Challenge Indisputable, e-Business is shaping the future inspiring a growing range of innovative business models. To bring it to the point: the Internet has redefined the way electronic business is performed. In an electronic supported business all relationships are transformed -may it be a seller-to buyer relationship or a an agency-to-citizen relationship. So for instance in commerce new business models incorporate various activities: promoting and communicating company and product information to a global user base; accepting orders and payments for goods and services; providing ongoing customer support; getting feedback and spurring collaboration for a new product development. There are several ways of further differentiating e-Business such as sketching some diversions on various levels: e-Commerce, e-Government; B2C, B2B, B2G, G2C; Customer Relationship Management, Business Intelligence and so on. Further distinctions may follow divergent criteria such as separating in business stages. Thus particular problem domains emerge. They all state of its own guiding the development of adequate information systems.

Buch. Zustand: Neu. Neuware - Wireless Local Area Networks (WLANs) experience a growing popularity recently. Where WLANs were primarily used for niche applications in the past, they are now deployed as wireless extensions to computer networks. The increase of the datarates from 2 Mbps up to 11 Mbps for roughly a constant price has played a major role in this breakthrough. As a consequence, an even greater success can be envisioned for the more recent OFDM-based WLAN standards in the 5 GHz band, which offer up to 54 Mbps. At IMEC we have realised this potential already several years ago and have established a successful research programme on OF- based WLAN. In 1995, we started our research on wireless OFDM in the frame of a - operation project with SAIT, a Belgian telecom company. The goal of the project was to establish a robust network for industrial environments. This resulted in a first OFDM chip, supporting QPSK, for wireless networking at the end of the project (1999). 1999 was also the start of an intense co-operation with National Semiconductor Inc., which resulted in a second generation ASIC in 2000. This OFDM processor supports up to QAM-64 and has a more optimal channel estimation algorithm.

Buch. Zustand: Neu. Neuware - CMOS Circuit Design for RF Sensors is about CMOS circuit design for sensor and actuators to be used in wireless RF systems. The main application is implantable transducers for biomedical purposes such as sensing of nerve signals and electrical stimulation of nerves. Special focus is put on the power and data link in a wireless system with transducers which are powered via the RF link. Novel principles and methods are presented for the regulation of power to the sensors and for the distribution of data and power in an implanted transducer system. One of the main problems in such systems is the transmission of power via an RF link. This problem is analyzed in detail and solutions incorporating an RF magnetic link to the transducers are identified. The theoretical results are supported by experiments from CMOS chips including a system chip for functional electrical stimulation (FES).

Buch. Zustand: Neu. Neuware - The origins and development of civilization are vital components to the understanding of the cultural processes that create human societies. Comparing and contrasting the evolutionary sequences from different civilizations is one approach to discovering their unique development. One area for comparison is in the Central Andes where several societies remained in isolation without a written language. As a direct result, the only resource to understand these societies is their material artifacts.In this second volume, the focus is on the art and landscape remains and what they uncover about societies of the Central Andes region. The ancient art and landscape, revealing the range and richness of the societies of the area significantly shaped the development of Andean archaeology. This work includes discussions on: - pottery and textiles; - iconography and symbols; - ideology; - geoglyphs and rock art.This volume will be of interest to Andean archaeologists, cultural and historical anthropologists, material archaeologists and Latin American historians.

Buch. Zustand: Neu. Neuware - Foundations of Information Technology in the Era of Network and Mobile Computing is presented in two distinct but interrelated tracks: -Algorithms, Complexity and Models of Computation; -Logic, Semantics, Specification and Verification.This volume contains 45 original and significant contributions addressing these foundational questions, as well as 4 papers by outstanding invited speakers. These papers were presented at the 2nd IFIP International Conference on Theoretical Computer Science (TCS 2002), which was held in conjunction with the 17th World Computer Congress, sponsored by the International Federation for Information Processing (IFIP), and which convened in Montréal, Québec, Canada in August 2002.

Buch. Zustand: Neu. Neuware - The 11 th IFIP International Conference on Very Large Scale Integration, in Montpellier, France, December 3-5,2001, was a great success. The main focus was about IP Cores, Circuits and System Designs & Applications as well as SOC Design Methods and CAD. This book contains the best papers (39 among 70) that have been presented during the conference. Those papers deal with all aspects of importance for the design of the current and future integrated systems. System on Chip (SOC) design is today a big challenge for designers, as a SOC may contain very different blocks, such as microcontrollers, DSPs, memories including embedded DRAM, analog, FPGA, RF front-ends for wireless communications and integrated sensors. The complete design of such chips, in very deep submicron technologies down to 0.13 mm, with several hundreds of millions of transistors, supplied at less than 1 Volt, is a very challenging task if design, verification, debug and industrial test are considered. The microelectronic revolution is fascinating; 55 years ago, in late 1947, the transistor was invented, and everybody knows that it was by William Shockley, John Bardeen and Walter H. Brattein, Bell Telephone Laboratories, which received the Nobel Prize in Physics in 1956. Probably, everybody thinks that it was recognized immediately as a major invention.
