Book Reviews
1982 F.E. Cellier (Editor): Progress in Modelling and Simulation. Academic Press, London, 1982, 466 pages, g30.00, ISBN o-12-164780-3. Proceedings of the course presented during the IASTED Conference “Simulation ‘80” in Interlaeken. The major intention of this course was to summarize recent research efforts in the field of modelling and simulation methodology through invited lectures by well-known specialists, This volume is intended to help the reader to: _ consolidate previously acquired knowledge on modelling and simulation by placing it in a unified framework; _ open new perspectives for him of techniques and applications of simulation. Contents: Part Z: Progress in Modeling: Ill defined systems modelling (3 papers); Large-scale systems modelling (5 papers); Experimentation with models (1 paper); Modelling systems (1 paper). Part ZZ; Progress in Simulation: Large scale systems simulation (5 papers); Simulation software design (1 paper); Simulation systems (3 papers). A. Javor (Editor): Discrete Simulation and Related Fields. North-Holland Publishing Company, Amsterdam, 1982, 246 pages, Dfl. 75.00, ISBN O-444-86429-6. Proceedings of the IMACS European Simulation Meeting held in Kerzthely, Hungary on lo- 12 September 1980. The papers presented in this volume tackle with the subject of the meeting from various angles: methodology and principles of simulation, simulation systems and language design principles, various fields of applications, digital logic simulation and testing to be used as CAD tool, and the emerging possibilities provided by the boom of microelectronic technology in application of new parallel processing-multiprocessor based computing systems. Contents: 1, Philosophy, methodology, general questions (5 papers); 2. Simulation systems (9 papers); 3. Applications (9 papers); 4. Round table report: Future tools of simulation versus the

G.A. Keramidas: Variational Analysis and Approximate Solutions for Transport Phenomenas. Naval Research Laboratory Memorandum No. 4852, 1982, 82 pages, Washington, DC. Certain concepts of classical mechanics are utilized to derive the variational formulation for a field partial differential equation. By introducing suitable parameters, it is demonstrated that the concepts of virtual work and generalized coordinates can be extended to the general transport equation and this equation can be translated into Lagrange’s equations of mechanics. The system of equations may represent a large number of physical processes and it is not restricted by any means to a particular problem. The Lagrangian system of equations is most suitable for deriving approximate solutions and this is demonstrated by assuming a linear series expansion in terms of the generalized coordinates. furthermore, it is shown that approximate methods, such as the finite element method, can be directly derived as a special application of the generalized approach. Examples of approximate solutions are given for some typical problems encountered in transport processes. Contents: Introduction. Basic equations and definitions. Variational analysis: Fundamental variational principles, complementarity variational principles, Generalized coordinates. Approximate methods: Linear functionals, Finite element method (Displacement models and Conventional models). Numerical applications: Problem definition, Error analysis (Displacement models, Conventional models), Convergence of the numerical solution, Numerical examples (Advection equation, Convection-diffusion equation, Diffusion equation). Summary and conclusions, Akcnowledgements, References. T. Moto-Oka (Editor): Fifth Generation Computer Systems. North-Holland Publishing Company, Amsterdam, 1982, 286 pages, Dfl. 149.00, ISBN o-444-86440-7. Proceedings of the International Conference held in Tokyo in October 19-22, 1981.
