Abstract

During the past ten years the Soviet Bloc has designed, developed, and put into production a series of upward-compatible third-generation computers known as the Unified System or Ryad. This family is effectively a reverse engineering of the IBM S/360 system. Although backward by current Western and Japanese standards, the Unified System is of considerable technological, political, and economic importance. This paper is an attempt to present a comprehensive survey and analysis of the Ryad project. [ABSTRACT FROM AUTHOR]

Abstract

This article presents an engineering technological information regarding works of making of a new "flying train" in Japan as reported by the "New Scientist," a news periodical. It is reported that engineers in Japan are trying to develop the train using the "wing-in-ground" (WIG) effect, in which a high-pressure cushion of air forms beneath flying objects as they approach the ground. They believe that they can create trains that use only a quarter of the power required for magnetically levitated trains. Describing one of the model called Aerotrain, it was shown that the WIG effect can be used only when the train reached at the speed of 50 kph.
