Biohydrogen production with fixed-bed bioreactors
Jo-Shu Chang

An investigation on anaerobic hydrogen production was conducted in fixed-bed bioreactors containing hydrogen-producing bacteria originated from domestic sewage sludge. Three porous materials, loofah sponge (LS), expanded clay (EC) and activated carbon (AC), were used as the support matrix to allow retention of the hydrogen-producing bacteria within the fixed-bed bioreactors. The carriers were …

Multiple targets characterization of electromagnetic vulnerability
Tiee-Jian Wu

The proper functioning of a complex electronic system is increasingly threatened by electromagnetic interference (EMI) from internal sources and high-power external sources encountered in their operating environments. Because experimental testing of the electromagnetic compatibility of these systems in their operational environments comes late in the acquisition process, simulation tools are …

INTERMODAL COMPETITION WITH HIGH SPEED RAIL- A GAME THEORY APPROACH
Oliver Feng-Yeu Shyr

Before the inauguration of Taiwan High Speed Rail (THSR) in January of 2007, it was estimated that approximately 50% of the air trips, 20% of rail trips, and 15% of freeway bus trips in Taiwan’s western corridor would be replaced by the new competitor. With relatively remote locations of its stations, poorer service quality, and more expensive fares, THSR did not attract most of the passengers …

An Embedded Isolation Moat Structures With Wide Stopband and Low Parasitic Effect for Elimination Simultaneous Switching Noise
Mau-Phon Houng

we use two embedded isolation moats which have different size to obtain the wide stopband elimination performance. The proposed structure is realized by embedding the double isolation moats between power and ground planes. The suppression frequency range of the proposed structures is from 1.2 to 7.2 GHz and the peak noise improvement in time domain is 36%. Furthermore, the proposed structure uses …
