Abstract: A remote power automatic meter reading system based on GPRS is introduced in this paper. The system using GPRS for communication and collecting the energy data in real-time, realize the optimization of the system resources. The components, structure, working process and the GPRS wireless transmission used in the remote power automatic meter reading meter are described and the practical application shows that the system obtained the desired results.

Abstract: Vehicle License plate recognition system includes license plate location, character segmentation, character recognition three important aspects. Image Processing is the VLPRS is one of the three key technologies, this gray-scale transformation of the image, contrast enhancement, image smoothing, edge detection, binarization and other methods were discussed and studied through the Image Processing technology to improve image Quality, strengthen the image area. Experimental results show that this treatment method is simple, real time, dealing with the right rate to achieve a practical standard.

Abstract: Auto-loading system is as an important part of weapons and equipment, its work reliability determines the combat effectiveness and their own safety of weapon systems. As the core of the automatic loading system control, the control software’s reliability of automatic loading system is especially important. In introducing the importance of software testing, from the basic method of software testing starts, design methods is detailing on test and a case of black box test of the automatic loading system, and finally, combined with the equip software testing, software evaluation model was constructed, Results consistent with test results from platform, shooting range, altitude, cold regions, thermal zone, they are proved the software testing and evaluation are valid.

Abstract: Community structure is a common property that exists in social networks. Community structure analysis is important for understanding network structure and analyzing the network characteristics. Recently community detecting methods are reported continually, but within community the structure is still complex. This paper proposed a method applied to classify community by using Laplacian spectrum feature, and defined the distance measure between the features extracted from difference community. As experiments, this paper studied three complex network models: the random graph of Erdös-Rényi, the small world of Watts and Strogatz and the scale-free graph, and classified them based on Laplacian spectrum feature successfully. The result shows the Laplacian spectrum feature and similarity measure are effective for classification.

Abstract: In this paper, the numerical solutions in pure squeeze motion are explored by using hydrodynamic lubrication (HL) and elastohydrodynamic lubrication (EHL) models at constant squeeze velocity with power law lubricants. This paper also proposes a closed form solution to calculate the relationship between central pressure and central film thickness under HL condition. In order to save time calculation, the present closed form solution can be used as the initial condition for analysis of EHL at the high-pressure stage. In addition, this paper also discussed the HL and EHL squeeze film characteristics.

Abstract: With the severe competition in the market, the risk that enterprises are faced with is more and more big. But so far, the development of the risk early-warning management system of enterprises in China is relative laggard. Based on this background, the theory of integrate risk early-warning system is studied and applied in Enterprise. The author hopes that it can offer some use to researching on enterprise integrated risk early-warning management.

Abstract: After researching the mould coating and the effect of different matrix hardness on the service life, it can be concluded that under the condition, the matrix materials match with its obdurability well, the higher the matrix hardness, the longer the service life after the mould’s being coated. What’s more, it is put forward that when the heat treatment technology and the coating technology are worked out, the effect of the coating temperature on the matrix hardness should be turned over so as to avoid the matrix’s being annealing again and then have a further influence on the capability after being coated.

Abstract: The paper is focused on the Min-Max Vehicle Routing Problem (MMVRP). Tabu search algorithm is an algorithm based on neighborhood search. According to the features of the problem, the essay centered the longest route to construct neighborhood structure. For the operation, 1-move and 2-opt were applied, it can also fasten the speed of convergence, and boost the search efficiency. Finally, the good performance of this algorithm can be proved by experiment calculation and concrete examples.

Abstract: The enterprise information integration (EII) based on service-oriented architecture (SOA) is a good methodology to solve power enterprise application integration (EAI). A business information integration platform is built to solve problems the power enterprise EAI based on SOA, and a technical solution is introduced on the architecture through a practical case of power enterprise information integration.

Abstract: A DSS of business-oriented theme has been established by using the EPM information integration platform. Under the EPM business requirements, the DSS toolkits have been solved and a comprehensive algorithm for decision support has been achieved on the basis of these toolkits. Through a practical application case, the analysis reports and the prediction evaluations for the EPM business can be processed flexibly with this system.
