CABLE manufacturing, SUPERCONDUCTING cables, RUNNING training, ELECTRIC potential, and SUPERCONDUCTING films
Aiming to achieve a superconducting feeder cable system applicable to Japan, France, and other countries, we summarize the required specifications created for prototyping of superconducting cables. Superconducting cables manufactured based on the required specifications were subjected to voltage, current, and other tests and then verification tests using train. The abovementioned test results have given us good prospects for superconducting feeder cables that can be applied to actual lines in Japan and France. Simulation was conducted to check the effect of these superconducting cables in actual lines. Analysis results were obtained to confirm that the introduction of a 310-m superconducting cable had an effect of compensating for voltage drops. [ABSTRACT FROM AUTHOR]

ARTIFICIAL intelligence, PROGRAMMING languages, EXPERT systems (Computer science), DECISION support systems, and FIFTH generation computers
This article focuses on the Fifth Generation project of the Japanese Ministry of International Trade and Administration aimed to develop symbolic inference machines capable of reasoning through massive amounts of knowledge and data. The project's ten-year plan is divided into three successive stages. The first three-year stage is devoted to the development of a prototype machine, a personal PROLOG workstation that will have a knowledge base comparable to present-day expert systems but whose reasoning powers will be a million logical inferences per second. The second four-year stage is for engineering experimentation, prototyping, continuing experiments at significant applications, and the initial experiments at systems integration. The first thrust at the major problems of parallel processing will be done in those years. The final three-year phase will concentrate on advanced engineering, building the final major engineering prototypes, and further systems integration work. Thus Fifth Generation machines will understand spoken, written, and graphical input.
