With widely use of pervasive computing, intelligent transportation system becomes more and more important in traffic management. Compared to some technologies, this paper constructed a detection and tracing algorithm of moving vehicles by using position prejudge and template matching technologies. Applied template matching technology can solved vehicles blocked or split, when tracking vehicle, and...
A semi-physical virtual reality system applying to MSV (manned submersible vehicle) control study is presented in this paper. This system is composed of three nodes: (1) control node for receiving sensors information and sending control command, (2) virtual sensors node for virtual devices and sensors and (3) Visualization node for virtual ocean environment and displaying the posture of MSV. The control...
Single-crystal GaN films have been deposited on (0112) sapphire substrates using trimethylgallium (TMGa) and NH 3 as sources. The morphological, crystalline, electrical and optical characterizations of GaN film are investigated. The carrier concentration of undoped GaN increases with decreasing input NH 3 -to-TMGa molar flow ratio.
