SUPERCONDUCTING cables, RUNNING training, ELECTRIC potential, SUPERCONDUCTING films, and CABLE manufacturing
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]

INFORMATION & communication technologies, TECHNOLOGY, INTERNET of things, and EDUCATION
Since 2001, the departments of Electrical and Electronics and Information and Communication Electronics Engineering of Faculty of Engineering, the University of Tokyo (UTokyo) have jointly given a lecture on autonomous electronic information devices for undergraduate students. According to the on-line questionnaire, 80% of students in 2010-2012 replied that the lecture was useful for their future career. The task given to students was to design and realise an autonomous electronic information devices (so-called 'the IoT-gadgets') by themselves, and conduct a live demonstration in front of their colleagues. The device must have an 'input', 'output', and some 'information processing'. Being aware of the speed of technology evolution as well as the short hours of the lecture, the professor tried not to give direct answers to students' questions on how-to instantly build and program an information device. Instead, the students were told to beware of their 'methods'. This refers to the deductive thinking introduced by René Descartes, and in the lecture's context how students should behave in order to realise the device. In this study, the backgrounds of various associated topics are discussed, such as the UTokyo's educational system, the world's rapid prototyping movement, open hardware, course design, students' reactions, and future directions.

FIFTH generation computers, ARTIFICIAL intelligence, PROGRAMMING languages, EXPERT systems (Computer science), and DECISION support systems
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.
