    STUDIE SDEVOTED TOP REDETERMINATION of ground resistance on the basis of geometric dimensions and ground resistivity generally assume that the resistivity of the soil is uniform. While this assumption is frequently justified in view of the usually meager knowledge of the actual ground resistivity distribution and the mathematical difficulties caused by any nonuniformity of the ground resistivity, ...

    LEONID ALEXANDER UMANSKY was born in Nikolaiev, Russia, an industrial and shipbuilding town, on July 23, 1890. His father was a mechanical engineer, and some of his forebears, including a grandfather who pioneered the coal mining industry in southern Russia, were engaged in one form or another of industrial activity. After the usual boyhood training in what we call the elementary and high schools,... View full abstract»

    I WOULD BE LESS THAN HUMAN if I did not feel a deep gratitude to the Institute, and its Edison Medal Committee for the high honor bestowed on me—and if I did not feel a certain amount of pride in this honor. Yet, I fully realize that, although an individual is often singled out, it is really associates amongst whom he has spent his active years, that jointly deserve the honor. These associa...

    IN THE PAST FEW YEARS a great interest has developed in the use of digital computers for solving the engineering problems of utility companies. The utility engineer already was familiar with t h e use of computers such as the network analyzer for power system studies, but many types of problems were encountered which were either long and tedious or impossible of solution on the network analyzer.

    MOTOR NOISE must be reduced to ever lower levels to meet the new demands of motor users. Today, an increasing awareness of noise is largely caused by the progressive mechanization of our lives, requiring use of noise-producing machines, as well as by the emphasis in recent years on physiological and psychological effects.

    X-ray studies of the internal workings of critical moving components have been hampered until recently by the inability to obtain a satisfactory brightness level. Through use of image intensification, it is now possible to make X-ray motion studies in many applications previously considered impractical. View full abstract»

    MAGNETIC-AMPLIFIER CIRCUITS, which once were limited to several-cycle delays, have been improved by the availability of high-performance rectangular core materials, as well as by the introduction of circuits which yield a complete response within a half cycle. The adoption of pulse techniques, which employ only magnetic and semiconductor materials, has made it possible to design decicycle magnetic... View full abstract»

    A FREQUENCY TRANS DUCER recently developed uses a circuit that converts frequency into d-c millivolts. Any standard d-c millivoltmeter, either indicating or recording with dial or paper marked in cycles, may be used to measure its output, thus simplifying and broadening the scope of frequency meters.

    PREVIOUS AIEE REPORTS covered the performance, operation, and maintenance of shunt capacitors.1,2 These reports contained little information about capacitor switching. In recent years, the use of switched capacitors has increased. This report has been formulated to provide a resume of existing literature and known experience concerning the factors to be considered in such applications. View full abstract»

    A SIMPLE CONTROL and /or memory circuit of four coils represents 24 = 16 possible combinations. The mental juggling required to keep these sorted calls for a properly organized score card. Relay requirements can be minimized and the score card, or “map,” delineates circuit synthesis. View full abstract»

    Studies in preparation for the installation of a second unit at Hiwassee Dam showed that the 26-per-cent additional installed cost of a pumpturbine-type unit was justified by economic and operating advantages. Design and operation characteristics of this 80,000-hp unit, as well as the field test to begiven after initial operation, are discussed. View full abstract»
