Book NOTES
mately twenty-two guest speakers, all specialists in the field, participated in the course entitled, " A Survey of Nucelar Engineering for Management." The purpose of this survey course was to present on a management level the fundamentals of nuclear engineering, in order to help management personnel understand some of its problems. Basic engineering principles or method of approach for the solution of engineering problems are therefore not discussed. The presentation of material is then directed toward the mature industrialist with an engineering degree, but inactively engaged in engineering for five to ten years. ELECTRICAL NOISE, by W. R. Bennett. 280 pages, diagrams, 6 X 9 in. New York, McGraw-Hill Book Co., Inc., 1960. Price, $10.00. This book presents a comprehensive account of how noise originates in electrical circuits, how it is measured, and how circuits may be designed to minimize undesirable effects from noise. It describes in qualitative terms the physical nature of various important noise sources, including thermal agitation or resistance noise, shot noise in vacuum tubes and semi-conductor junctions, noise from spontaneous emission of electromagnetic radiation, and noise in gas discharges. The fundamentals needed for analyzing basic sources of noise are stressed as well as the methods of measurement and design. In addition to the standard theory of noise figure and its significance, a treatment of the more comprehensive Haus-Adler theory of noise measure is given. The author also reviews noise in the various methods of signal transmission such as amplitude modulation, frequency modulation, and the different kinds of pulse modulation. MANAGEMENT CONTROL SYSTEMS, edited by Donald G. Malcolm and Alan J. Rowe. 375 pages, diagrams, 6 X 9 in. New York, John Wiley & Sons, Inc., 1960. Price, $7.25. These are the proceedings of a symposium held at the System Development Corporation in Santa Monica, California, July 29-31, 1959. A comprehensive treatment on management controls by some thirty experienced individuals in all areas of management is presented

in this volume. The editors and contributors have constructed a case for "designed" controis to produce better results in management patterns now and for the long-range future. The problem of designing adequate controls is herein given careful consideration, especially in relation to the fact that the design of systems is currently at best a systematic process rather than one where analytical evaluation is possible. Special attention is given to computers and their role in this problem. Contributors to this symposium have described and weighed the advantages of using computer applications to simulate company activities so as to create a management-laboratory where the effects of policy and procedures can be tested and evaluated prior to their adoption. COMPUTER LOGIC: THE FUNCTIONAL DESIGN OF DIGITAL COMPUTERS, by Ivan Flores. 458 pages, diagrams, 6 X 9 in. Englewood Cliffs, New Jersey, Prentice-Hall, Inc., 1960. Price: $12.00 (trade); $9.00 (text). This volume is the first of its kind to offer a complete block diagram analysis of each operational unit of a digital computer---describing and illustrating in detail just how a computer is put together and how it works. The author emphasizes the organization and functional interrelation of fundamental units and discusses these relationships from the viewpoint of operational necessity rather than mathematical logic, Boolean algebra or circuit theory. Especially helpful to the reader is the extensive treatment given two oftenneglected topics: ( I ) i n p u t / o u t p u t and (2) control of computer function. Problems are included that provide a means of acquiring facility with computer terms, and the final chapter reviews in detail what happens from the time the programmer receives the problem until the answer is ready. A complete glossary of terms is provided at the end of the book. ELECTRICAL ENGINEERING PROBLEMS, by E. M. Williams and F. J. Young. 294 pages, diagrams, 6 X 9 in. New York, McGrawHill Book Co., Inc., 1960. Price, $7.75. A collection of engineering problems ideally suited for laboratory activities is presented in this volume. Ranging from intermediate
