Methods: Using information engineering technology to establish a set of information platforms for health law enforcement and administration management, then combine the data resources from all the national, provincial and municipal information platforms and develop a set of data analysis and Early warning mechanisms. Results: The municipal information platform was established and put into use successfully in Qingdao health inspection bureau. Conclusion: The application of the information system improved work efficiency greatly, reduce administrative cost, and helps the authorities to comprehensive grasp of the health law enforcement situation, scientifically assess, early warn, timely and effectively intervene and correct the health law enforcement works in the health inspection agencies.

Abstract: Based on MIMO state feedback linearization, the suspension module control system model had been established, and it completed decoupling between double suspension points. Double-suspension system model is very accuracy for investigating stability property and control algorithm of suspension control system. When magnetic flux signal is taken back to control system, suspension modules antijamming characteristics for resisting suspension load variety and external force interference has been enhanced. Some experiments had been done on CMS04 magnetic suspension vehicle in national mid-low speed maglev experiment field of Tangshan city in China. Therefore, the stable property of double-electromagnet suspension control system has been enhanced.

Abstract: Tracking objects in the video sequences remains challenging problems such as occlusion and changes in appearance. Recently, the tracking-by-detection framework is widely used. We propose a simple and effective framework based on tracking-by-detection to determine the target position. The main idea is to combine Random Ferns and Implicit Shape Model. By combining these two detection methods, the position of a target can be tracked even when it is not fully appeared. Experiments show significant improvement in handling 3D-motion, fast appearance change and background clutter. We only focus on one target tracking problem.

Abstract: A MEMS variable optical attenuator (VOA) with only one shutter for dual signals simultaneous operation is designed for advanced tuning functions. Theoretical electro-mechanism model has also been developed to provide optimization for the VOA design. In experiment, the fabricated VOA device has demonstrated a over 40-dB attenuation range with respect to the driving voltage of one shutter, and it has also realized low polarization-dependent performance. The superior specifications make this device very promising for optical network systems and laboratory equipment.

Abstract: The system of uranyl nitrate aqueous solution and tributylphosphate (TBP) dissolved in kerosene is widely used all around the world, no matter in nuclear fuel cycle or analysis of impurities in uranium. The extraction process is mature, but the amount of consumption of organic reagent and generation of radioactive waste solution is huge, that is not environment friendly. Microfluidic is very popular nowadays, and one of its many applications is extraction. Here in this paper, we studied the flow situation of water and 20%TBP-kerosene, find the relationship between width ratio and flow rate ratio. And we used chemical modification to get a good separated outlet, and we observed the stability of OTS modified glass, that is stable in our circumstance. Finally we use the modified channels to achieve the extraction process, and find the extraction ratio is increases by contact time increases, and has no relationship of initial concentration.

Abstract: In this paper, a monolithically integrated device composed of optical switch (OS) and variable optical attenuator (VOA) is described. The device shows more functionality and more compactness in the all optical networks. Besides the advantage of wide attenuation range, its fabrication is simple and reliable. In our laboratory, a monolithically integrated optical device has been fabricated and setup for investigation. Experimental results have shown that the proposed approaches improve the compositive performance.

Abstract: this thesis puts forward the idea of using the searching method to retrieve two kinds of data points of the circle and the square to generate DEM data of the collected discrete points by means of using C# language and OpenGL DLL, thus realizing the visualization of the three-dimensional virtual terrain from contours on the two-dimensional surface. This thesis makes a comparison and analysis of the visualization effect which indicates that this algorithm is quick and effective. This research has a certain reference value for the formation of the virtual battlefield terrain.

Design computing from function-to-form mapping and shape decomposition etc is reported. Modelling of non-manifold polyhedron is the key issue to develop function to form mapping process; and research on function to form mapping could help to develop the creative computational design tools.

Abstract: Owing to high performance and tiny size, micromechanical radial-contour disk resonator as competitive candidate demonstrates an impressive prospect to replace traditional frequency selecting module in RF devices, so as to improve performance of modern RF transceivers. The influence of package atmospheres on resonance performance of micromechanical radial-contour disk resonator was investigated. By model construction and FEM calculation, resonance performance of micromechanical radial-contour disk resonator was analyzed, which indicate its resonance frequency as well as unique deformation style. In addition, effect on resonance performance of radial-contour disk resonator caused by package atmosphere was analyzed. The analysis result of resonance parameters variation of resonator immerged in different gases reveals that as the gas viscosity increases, the resonance frequency decreases. The phenomenon was interpreted by damping effect and recovery delay of disk deformation introduced by gases, which can be a reference for micromechanical resonator design and package selection in different applications.
