Switching theory is concerned with the development of models and techniques for the analysis and synthesis of those circuits in which information is represented in discrete or digital form, as opposed to the analog form in which information is represented in a continuous manner. The application of digital techniques over a wider range of human activities has already profoundly affected modern life, and there is no visible limit to their future utility.

Elements of Neutron Interaction Theory is a first-year textbook for graduate students in nuclear engineering, dealing with the interactions of neutrons, photons, and charged particles with nuclei, atoms, and electrons. The aim of the book is to present, as simply as possible, those aspects of neutron interaction theory which follow directly from conservation laws and elementary quantum mechanics. It is intended to be understood by anyone who has obtained the equivalent of a bachelor's degree in physics, chemistry, or one of the engineering disciplines.

"Nature designs everything from atoms; hence, we should be able to create any feasible kind of material and device with foresight, if we understood the Periodic System in all its implications. Yet—like weather forecasters—we find ourselves still members of the gambling profession." This was the tenor of the third summer session on modern materials research sponsored by the Laboratory for Insulation Research at MIT in 1963. Its program—organized by Arthur R.

The national interest in large radio and radar telescope systems spans the entire engineering and scientific community, and there is every indication that the country will embark upon the construction of still more of these systesm in the near future. Radio and radar astronomers now require very large mechanical devices. The system specifications lead to structural criteria which are unique and outside the immediate interest and/or capability of most of the structures community.

Rapidly quenched metals are the subject of an increasing research effort, spurred on both by advancements in metal processing techniques that have made commercial utilization of these metals feasible and by the recent discoveries of unique and potentially useful properties of these materials. Among the processes that have been perfected is "splat cooling," in which a liquid metal is cooled by being spread as a thin film against a metal substrate. Other processes involve vacuum evaporation, "sputtering," and chemical deposition.

The advanced model rocketeer will find that this book allows him to predict every aspect of his model's performance. It is a comprehensive and rigorous treatment of the trajectory analysis, aerodynamics, and flight dynamics of model rockets; it contains many original methods and demonstrates a wealth of complex problems that still require solutions in model rocketry.

Theory and Applications

This is the first full exposition in print of a subject in whose development over the past fifteen years the author has been a prime participant. As an approach to the study of mechanical vibrations, statistical energy analysis (SEA) has found new applications and adherents with each passing year. The name SEA was coined to emphasize the essential feature of the approach: "Statistical" indicates that the dynamical systems under study are presumed to be drawn from statistical populations or ensembles in which the distribution of the parameters is known.

Solar Resources takes stock of the resource - sunlight - on which any plan for solar heat conversion technologies must be based. It describes the evolution of theoretical models, algorithms, and equipment for measuring, analyzing, and predicting the quantity and composition of solar radiation, and it reviews and directs readers to insolation databases and other references that have been compiled since 1975.

Artificial Neural Networks (ANNs) offer an efficient method for finding optimal cleanup strategies for hazardous plumes contaminating groundwater by allowing hydrologists to rapidly search through millions of possible strategies to find the most inexpensive and effective containment of contaminants and aquifer restoration. ANNs also provide a faster method of developing systems that classify seismic events as being earthquakes or underground explosions.

Algorithms and Codes

Large-scale optimization is becoming increasingly important for students and professionals in electrical and industrial engineering, computer science, management science and operations research, and applied mathematics.
