Radiation detection and measurement

introduces the reader to the DARE P simulation system. The DARE P system is an equation-oriented continuous system simulation language developed by the authors at the University of ArizonaIt is designed for batch-mode processing, and the system programs are coded in ASNI Fortran IV. Several examples from the disciplines of electrical circuits, control systems, and aerospace engineering are given to illustrate the versatility of the DARE P system. In Chapter 5 the design and application of minicomputer interactive stimulation systems is described with particular reference to the DARE/ELEVEN system. Chapter 6 describes methods for increasing the computing speed of the simulation language. A comparison of the performance of different simulation-language systems is also given. Appendix A contains a discussion of integration routines. Appendix B contains Fortran subroutines while Appendix C discusses numerical techniques. Since the general purpose digital computer is replacing the analog computer as the primary tool of engineers and scientists for the simulation of continuous time systems, a book on this subject is important to the scientific community. This book is valuable in that it gives a simple overview and a logical development of the subject, and together with the DARE package enables the user to obtain a digital simulation of a continuous system without becoming overly involved in the intracacies of the simulation language itself. In our opinion this book provides a good introduction to the subject of digital simulation of continuous systems. It is not suitable as a classroom textbook. However, to those who avail themselves of the DARE system (the programs are available from the authors at a nominal cost) it would serve as a valuable companion to the users’ manual. Unfortunately the book is difficult to read. The authors use specific terms and phrases without adequately defining them. In many instances the narration is too brief and confusing. The technique of providing explanations under the figures themselves rather than in the main body of the text makes for disjointed reading.
