Abstract: Through analyzing the current application of 3S Technology and MIS system, the paper puts forth the idea to establish the MIS system integrity based on 3S technology, and design the general structure model of the integrity system. The disadvantages of the above two systems can be overcome and their advantages can be complemented. The MIS system integrity based on 3S technology can be expected to offer a new thinking way and method for scientific research, governmental administration, and social production.

Abstract: Recently, the successful development of MAPGIS software in China has challenged the monopoly status of the GIS software programmed abroad. The following paper, with the assistance of MAGIS system platform, designs and realizes Xiaolangdi water conservancy dam digital sand table, and establishes 3D visualization system, which offers a new developing way for the application of domestic GIS system software and the management and monitoring of water conservancy project.

Abstract: As a kind of new renewable energy, biogas is receiving more and more attentions. However, its combustion duration is longer than diesel, which causes the bigger thermal load of engine. A geometry model of a biogas engine’s piston is set up in Proe 4.0. The temperature fields, thermal stress and thermal deformation of the piston are calculated using ANSYS 10.0. The result shows that the thermal load of biogas engine is still within the thermal strength of the material, thus provides supporting evidence for the popularity of biogas.

Abstract: By means of factor analysis and logistic regression approaches, this paper predicted financial failures of Chinese listed companis in 2009 from the published data in 2006 of those companies. The study confirmed that by introducing non-financial indicators, the predictive power of financial failure analysis model has been further improved, from 80.77% up tp 86.54%.

Abstract: The three-dimensional geometric kinematics model of the loading mechanism of back-loaded compressed dust cart is established based on the robot kinematics principle and Denavit-Hartenberg（D-H） method. In this paper, the loading mechanism's principle is discussed and it’s institutions simplified robotize model is established, coordinate transformation process and gesture of the skateboard and scraper of the loading mechanism have been studied in the D-H coordinate, has certain significance for improving the product design methods and the manufacturing quality.

Abstract: In this paper, we design a typical automated packaging salt system, including multiple devices to stir, feed, packaging, weighing and other links. This requires the coordination of all sectors to achieve sequential switch, equipment failure alarming and maintenance. Therefore, salt packaging system adopts PLC control. According to different control objectives and requirements, we allocated the address reasonably; selected PLC and the modules. GX Developer software is used to programming and finally the control panel is designed. After commissioning and practical application, the effect is good, efficient, and precise.

Abstract: In this paper, adsorption of methane in actived carbon pores has been simulated by using the grand canonical ensemble Monte Carlo (GCMC) method. In the simulation, Lennard-Jones (LJ) potential is used for represent the fluid-fluid interaction, and the 10-4-3 potential is used for represent the interaction between fluid molecules and a slit carbon wall. Firstly, the adsorption isotherms of methane in actived carbon pores and local density profiles of methane in slit pore are obtained. Then, the interaction energy of methane in slit carbon pores with nine different pore sizes is obtained. Finally, the temperature, pressures, pore sizes affect the adsorption amount was studied, respectively.
