According to the characteristics of Fast Speed Mirror, the paper discusses that, in a FSM composite axis control system, the mechanism of the servo control, the main system performance, the speed loop of subsystem and effects of automatic zero locking system. Combined with traditional methods, a new structure of axial subsystem is proposed, to improve the rapid high-precision tracking technique. From theory to experimental model, the paper made a detailed analysis.

This paper covers the current situation of remote monitoring system, combined with the basic features and running environment of GoAhead web server, Put forward the solution to integrate GoAhead web server, Internet, embedded development platform and Linux operation system, design a remote monitoring system. By which the user can monitor voltage and control the stepper motor’s running in real time. The application results show that GoAhead web server reacts rapidly manipulates data quickly. It’s feasible to put into place and to achieve satisfied effect for the management and control of the embedded product.

The surface subsidence resulting from coal mining can lead to terrible land damage, thus studying the distribution of surface subsidence under thick alluvium is of crucial significance.Focusing on the example of Henghe coalmine in Jining, Shandong province, this paperestablished the prediction model for main section and arbitrary points in mining areas based on the probability integration method, by which the size of subsidence, tilt, curvature, horizontal movement and deformation were predicted after the exploitation of coalbeds 2# and 3#. And the result, which is basically consistent with the actual situation, shows that subsidence areais 78 hm2 and the settlement reaches 9987mm. The thick alluvium covered the mining area accountsfor the greater surface subsidence coefficient, subsidence value, horizontal movement coefficient,horizontal movement, subsidence area and smaller deviation of inflection point.

China is a country prone to natural disasters, especially the flood disaster. In order to improve the villages and towns flood emergency management, through a series of methods such as information management and simulation, the establishment of emergency decision support using information technology to reduce losses caused by floods, the visualization technology is used in the virtual reconstruction model of floods, intuitive way to simulate the dynamic spread of the process of the flood disaster, in a safe and economical method to obtain the number of indicators of disaster-related decision. It provides a new method and ideas, and then it gives a reliable basis for the flood prevention and emergency management. The visualization analysis and decision is achieved for the villages and towns flood control, and it provides great support for the villages and towns flood mitigation and prevention. The result shows that the system is useful and meaningful in the town flood mitigation.

In order to achieve the national energy saving targets, and track, supervise, manage and assess the energy-using condition of the key energy-using enterprise effectively, according to the user’s demand and the system feature, the Microsoft.Net framework and the MVC mode are chosen, and combined with the Ajax technology, the implemented plan is settled. The .net-based energy-saving information management system is designed and implemented, and it improves the condition of the information reporting and statistical analysis mean for key energy-using enterprise and relevant functional departments. The result shows that the system architecture is reasonable, and it improves the maintainability and extendibility of the system.

In this study, we will discuss a fast spatial indexing structure called QR*-tree based on R*-tree and quad-tree. Now, R*-tree and R-tree are widely used in spatial database as a spatial indexing structure, But for each algorithm alone, it is not suitable for the huge data volume. The hybrid structure that we proposed is composed of many R*-trees based on space partitioned by quad-tree. Although it demands more storage space than R*-tree or quad-tree, it gains better performance in insertion, deletion, and searching especially, and the more the amount of spatial data is, the better performance the hybrid-tree has.

Location decision of Service Networks is important for an enterprise to dominate market and to improve service level. Characteristics and the decentralized control strategies of service network were discussed for the enterprise of Denso class. A 0-1 mixed integer programming model was established for location problem of spare parts centers and solved by ILOG along with sensitivity analysis. Furthermore, a dynamic programming model was established for location problem of sales model shop and calculated by a numerical listing method.
