Many studies have been conducted on supporting communication in home and office spaces, but relatively few studies have explored supporting communication in large-scale public spaces, despite the importance of such environments in our daily lives. We propose a transcendent means of communication as an emerging style in this pervasive computing era: a system(More)
Reducing IR-drop in the test cycle during at-speed scan testing has become mandatory for avoiding test-induced yield loss. An efficient approach for this purpose is post-ATPG test modification based on <i>X</i>-identification and <i>X</i>-filling since it causes no circuit/clock design change and no test vector count inflation. However, applying this(More)
Test data modification based on test relaxation and X-filling is the preferable approach for reducing excessive IR-drop in at-speed scan testing to avoid test-induced yield loss. However, none of the existing test relaxation methods can control the distribution of identified don't care bits (X-bits), thus adversely affecting the effectiveness of IR-drop(More)
We developed a 3D virtual space environment for social psychological experiments. By using this, researcher can conduct social psychological experiments quickly in the virtual space even if they don't have much knowledge on computer. There are two advantages for us to conduct these experiments in the virtual space. One of the advantages is elimination of(More)

This paper describes analyzing elements of letters in a letter management system. The primary elements of a letter are a sender, a receiver, and terms which are words and named entities appeared in the letter. A letter management system is developed for letters in the Avery Brundage Collection, named LMBC. By analyzing a collection of such letters,(More)
