    Engineers are concerned with the preparation of young men to serve a civilization and culture based largely upon the results of technological developments. This fact makes necessary a multisided, better educated, and more roundly interested individual. Combined with the increasing body of fundamental technical knowledge and high standards of technical education, the adequacy of a 4 year profession... View full abstract»

    The theory and design of a new distance relay suitable for ground protection are described in this paper, and the results of 2 groups of extensive field tests are presented. These results demonstrate that the new relay performs in a manner that can be predicted mathematically, and that it avoids certain difficulties involved in the application of conventional distance relays to ground protection.

    Carrier pilot relaying has been regarded by many as the nearest approach to a perfect protective relay system; however, it has not been adopted generally because of its high cost. With the intention of making still further improvements and reducing the cost of carrier pilot systems, a careful investigation has been made. The results of the investigation are presented in this paper, and a new carri... View full abstract»

    In this paper the mechanical failure of porcelain is discussed with special reference to 3 seldom recognized characteristics: the effect of the porcelain surface on the strength, the apparent anomalous distribution of individual mechanical test values, and the effect of time on mechanical strength. A method of evaluating the result of these factors on electrical insulator performance is suggested. View full abstract»

    More than half of the highway fatalities occur during the hours of darkness with a quarter of the daytime traffic volume. This is significant of conditions beyond the control of driver or pedestrian. Campaigns for education of driver and pedestrian, to be effective both day and night, must be accompanied by measures to improve night visibility, such as systems of fixed lights along the highways.
