This book constitutes the refereed postworkshop proceedings of the Fourth Canadian Workshop on Information Theory, held in Lac Delage, Quebec, in May 1995.
The book contains 18 revised full papers selected from 30 workshop presentations; also included are three invited contributions. The book is divided into sections on algebraic coding, cryptography and secure communications, decoding methods and techniques, coding and modulation for fading channels, and signal processing and pattern recognition.

This text presents an up-to-date treatment of the concepts and techniques applied to the performance evaluation of computer systems. Computer systems in this context include computer systems hardware and software components, computer architecture, computer networks, operating systems, database systems and middleware This book covers analystic, simulation and empirically tested techniques applied to the evaluation of systems software and the computer systems which support them. It can be used as a reference text for researchers and practitioners in the computer systems engineering and performance evaluation fields or as a single or multiple semester book on computer systems performance evaluation The purpose of this book is to make analytic, simulation and instrumentation based modelling and performance evaluation of database and computer systems components possible and understandable to a wider audience of database and computer systems designers, developers, administrators, managers and users. The book assumes the reader has a familiarity with concepts in computer systems architecture, computer systems software, computer networks and elementary mathematics including calculus and
