Among the group of physics honors students huddled in 1957 on a Colorado mountain watching Sputnik bisect the heavens, one young scientist was destined, three short years later, to become a key player in America’s own top-secret spy satellite program. One of our era’s most prolific mathematicians, Karl Gustafson was given just two weeks to write the first US spy satellite’s software. The project would fundamentally alter America’s Cold War... more...

The use of mobile communication devices has grown phenomenally throughout the world during the last few years. With strong consumer demand to increase data delivery (large emails, browsing the Internet on wireless devices, transferring video images, etc.), engineers are faced with the challenge of enhancing CDMA to provide larger data capabilities while improving voice signals for clearer reception. In November 2001 the U.S. Federal Communications... more...

Presents main concepts of mobile communication systems, both analog and digital Introduces concepts of probability, random variables and stochastic processes and their applications to the analysis of linear systems Includes five appendices covering Fourier series and transforms, GSM cellular systems and more

Alan Mathison Turing (1912-1954) made major contributions to several areas of science. Today his name is mentioned frequently in philosophical discussions about the nature of Artificial Intelligence. He was a pioneer researcher in computer architecture and software engineering - his work in pure mathematics and mathematical logic extended considerably further. His last work was "On Morphogenesis in Plants". Turing was one of the leading figures in 20th... more...

The topics dealt with are algorithms and data structures, applications, combinatorial enumeration, combinatorial optimization,... more...

Information is everywhere, and defines everything in today's society. Moreover, information is a key concept in a wide range of academic disciplines, from quantum physics to public policy. However, these disciplines all interpret the concept in quite different ways. This book looks at information in several different academic disciplines - cybernetics, ICT, communications theory, semiotics, information systems, library science, linguistics, quantum... more...


This book provides a concise survey of principles and state-of-the-art techniques for secure group communications (SGC) over data networks. It offers an overview of secure algorithms and protocols for group communication linking areas such as applied cryptography and computer networking. Also included is a coverage of challenges in deploying secure group communication-based applications over wireless networks. These challenges include the limited... more...
