Along with the request of higher precision method to identify more complex geological targets, higher precision and accurate information of oil reservoirs underground must be provided through geophysical technologies for reservoirs prospecting and developing. By digital grating sensor of vibration measurement, mechanical vibrating signal of the seismic wave can be transformed into light modulating signal - moire fringes, and then converts by photoelectric element to digital electrical signal. The sensor samples the signal by counting the numbers of the moire fringes, which may prevent quality of the output data from being influenced by electric circuits, and the packaging technology is also simplified. The working principle, theoretical arithmetic, configuration design, test method and acquired data by digital grating sensor are presented in the paper.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.

The sensitive properties of the film to H/sub 2/S were investigated, and the R-T relation was measured in temperature pulsed operation mode and in simple temperature ramp mode in order to understand the sensitive properties. The results are used to discuss the effect of Ag additive on the R-T relation and sensitive properties of the film. The variation of film resistance shows that the silver promotes the chemical processes on the surface of films.

First the method employs an energy function to extract a dummy skeleton of a human body from the silhouette, and then estimates the position of the joints by the knowledge of anthropotomy and three rules given by the standard human skeleton model. The three rules can help us to judge whether a point on the skeleton is a joint or not. The experimental results show that, the method is effective. It requires no any additional restrictions on the motion and color of a human body. Meantime the method is robust against the noise in the silhouette. Especially it has good performance in the case of complicated background.","PeriodicalId":297178,"journal":{"name":"International Conference on Information Acquisition, 2004.
