The term risk has experienced a dramatic growth in usage over the last few years. This is mainly due to the growing concern about the future of mankind, but also to a greater awareness of the limited nature of our resources. People want to know what can go wrong. In the beginning terms such as risk, disaster, indeterminacy and uncertainty are discussed in detail in this book. Furthermore disasters and risks are categorized into natural, technical, health and social risks, and then major disasters in these categories are listed. Risk parameters are introduced to allow the objective description of risks. The explanation of risk parameters (such as mortalities, fatal accident rates, the family of F-N curves and the concept of lost life years) leads to the quality of life parameters as measurements of risk. In general this parameter permits the comparison of the efficiency of all safety measures over the entire human society. However, limitations of this concept are also disclosed. The book clearly shows the interdependence of risk measures. Safety and risks cannot be discussed only by looking at specific problems, since increasing safety in individual fields might lead to a decrease of safety over the entire society. more...

This title explores what it means to be rational in a variety of contexts, from personal decisions to those affecting large groups of people. It introduces ideas from economics, philosophy, and other areas, showing how the theory applies to particular situations such as gambling and the allocation of resources. more...

Although recently they've become most closely associated with computer security, the art and science of cryptography have histories and applications stretching along disciplines and millennia. Mollin (mathematics, U. of Calgary, Canada) creates an accessible survey of that history from antiquity to the present, but rightly devotes most of his effor more...

There are two basic methods of error control for communication, both involving coding of the messages. With forward error correction, the codes are used to detect and correct errors. In a repeat request system, the codes are used to detect errors and, if there are errors, request a retransmission. Error detection is usually much simpler to implement than error correction and is widely used. However, it is given a very cursory treatment in almost all textbooks on coding theory. Only a few older books are devoted to error detecting codes. This book begins with a short introduction to the theory of block codes with emphasis on the parts important for error detection. The weight distribution is particularly important for this application and is treated in more detail than in most books on error correction. A detailed account of the known results on the probability of undetected error on the q-ary symmetric channel is also given. more...

The inaugural research program of the Institute for Mathematical Sciences at the National University of Singapore took place from July to December 2001 and was devoted to coding theory and cryptology. As part of the program, tutorials for graduate students and junior researchers were given by world-renowned scholars. These tutorials covered fundamental aspects of coding theory and cryptology and were designed to prepare for original research in these areas. The present volume collects the expanded lecture notes of these tutorials. more...
