This is a self-contained, modern treatment of the algebraic theory of machines. Dr Holcombe examines various applications of the idea of a machine in biology, biochemistry and computer science and gives also a rigorous treatment of the way in which these machines can be decomposed and simulated by simpler ones. This treatment is based on fundamental ideas from modern algebra. Motivation for many of the newer results is provided by way of applications so this account should be accessible and valuable for those studying applied algebra or theoretical computer science at advanced undergraduate...

Dr Peter Milton, Director of Programme Review, Quality Assurance Agency I am grateful to the authors for giving me the opportunity to write this foreword, mainly because it represents the first occasion that the Fund for the Development of Teaching and Learning (FDTL) has led directly to a pUblication such as this. In my former capacity as Director of Quality Assessment at the Higher Education Funding Council for England (HEFCE), I chaired the FDTL Committee during 1996/7 and am delighted to see the projects which were selected so painstakingly leading to successful outcomes. Assessment of...

Correct Systems looks at the whole process of building a business process model, capturing that in a formal requirements statement and developing a precise specification. The issue of testing is considered throughout the process and design for test issues are fundamental to the approach. A model (language) and a methodology are presented that is very powerful, very easy to use and applicable for the "new world" of component based systems and the integration of systems from dependable components. This book discusses a new area which will be of interest to both software and hardware...
