Noriaki IshiiNoriaki Ishii is Professor Emeritus, Osaka Electro-Communication University. He graduated from Kannonji-Daiichi High School in 1966 and entered the Department of Engineering Science of Osaka University as a member of their sixth graduating class. At saka University, he was well educated in using various methods to solve engineering problems, especially in the use of mathematical techniques. He studied the dynamic performance of centrifugal pumps in his B.S. thesis project and was awarded his B.S. degree in 1969. He then focused on the dynamics and performance optimization of reciprocating refrigerant compressors in collaboration with the Panasonic Company for his M.S. degree in 1971. After entering the doctoral Engineering Science course, he continued to study rotary rolling-piston refrigerant compressors and later scroll compressors. Ishii was not satisfied with studying small-sized engineering compressors, and so began his interest in investigating the dynamics of large hydraulic Tainter gates in 1972. His dissertation was on the failure analysis of Wachi-dam Tainter gate in Japan for which he received his Ph.D. from Osaka University in 1975. Immediately after his graduation, he joined the faculty at OECU. His main areas of research are in refrigerant compressor dynamics and optimization, flow-induced vibrations, and hydraulic gate instabilities. He has authored or co-authored over 97 journal articles and 146 conference papers. He holds Japan, European and United State patents entitled Hybrid Vehicle Driving System, Hybrid Vehicle, and Driving Method . Read More Read Less
