Speaker Prof. Harry H. YehThe Miles Lowell and Margaret Watt Edwards Distinguished Chair in EngineeringOregon State University Abstract Reflection of an obliquely incident solitary wave along a vertical wall may create the formation of the Mach stem. The previous laboratory and numerical experiments failed to validate the Mach reflection phenomenon predicted by Miles. Here we show that the discrepancy is primarily originated from the assumption of small incident wave angle. Ex- pressing the incident solitary wave with the quasi-two-dimensional Kadomtsev-Petviashvili (KP) theory, Miles's theory can be extended to the higher-order correction for the incident wave angle. With this revision, the laboratory and numerical results are now found to be in better agreement with the theory. Our results demonstrate that the ...

Speaker Prof. Shiaw-Shyan LUO Department of Transportation Management and Graduate Institute of Transportation Science Tamkang University, Taiwan Abstract The public transport is considered as the best solution to improve traffic congestion. Today it is urged to promote public transport to meet green environment and sustainable development. Based on the worldwide experiences we knew that it is not easy to promote public transport. Taiwan is a small island, major cities with high resident density are encountered with different level traffic problems and traffic is getting worse especially under current new urban development. Furthermore, the key role of the public transport is to take care of aged and handicapped. Residents in Taipei city and its adjoining cities use public transport often, the ...
