Editor's Note (Toru Nakagawa, Feb. 29, 2016)
I gave this Tutorial Lecture on USIT at ICSI 2015 held last July in Hong Kong. A lecture for 3 hours in English was my first experience, so I made much efforts for its preparation. I thought the completion of USIT Manual and A Collection of USIT Case Studies should be the best preparation. Thus I made them and published in Japanese on May 25, 2015 and also in English on Jun. 26, 2015.
This Tutorial is a full explanation of USIT to the beginners of it, using the USIT Manual and five USIT Case Studies (in A Collection of USIT Case Studies). It is the most comprehensive material for learning USIT. In the present page, the PDF file of the Tutorial slides (126 pages) and the outline of the talk are shown. In the Japanese page, only the outline is recorded.
Hints (TN, Feb. 29, 2016): In the PDF file
