Abstract: rrigation district informative construction is an effective way to improve the management and to rational allocate and effectively utility irrigation water resources. This paper is directed against the characteristics such as large-scale monitoring data amount, complex data types, high real-time requirement, strong spatial correlation, etc. combine Multi-Agent theory with irrigation district information system together, and use GSM communication network as the communication network of system, established an agricultural irrigation district information system based on Multi-Agent and GSM, which can full utility intelligent of Agent and the good communication coordination of Multi-Agent system, so to provide comprehensive technical support for irrigation management and decision making.

Abstract: This paper presents a novel omni-directional steering system for electric vehicle. In order to guarantee the stability and the steerability of the electric vehicle, the proposed novel steering system consists of 2 conditional front wheel steering configuration and 4 wheel omni-directional independent steering configuration. The design of the 2 conditional front wheel steering configuration can guarantee the stability and the steerability of the vehicle. And the four wheel independent steering can achieve omni-directional motions such as zero radius turning (ZRT) and later parking (LP). This system was tested in simulation environment, and the last performance evaluation demonstrates the validity of the proposed omni-directional steering system.

Abstract: In the context of endogenous infinite plane lattice, the literature [ characterizes the accurate features of equilibrium structure and absorbing set based on location strategic interaction under different levels of the cost of link formation. On this basis, this paper make further efforts on the stochastic stability of absorbing state in some specific circumstances.

Abstract: The booming e-commerce industry is suffering from serious information security problems. As a potential and effective security solution, information hiding technology has been widely applied in many fields and drawn unprecedented attention. Based on our research, this paper provides a survey on the current state of the art information hiding technology, mainly covering the fundamental concepts, basic model, the recent progress of information hiding methods and its applications in e-commerce security sector. At last, possible research and development trends of information hiding technology are discussed.

Abstract: This paper studied the Service-oriented software architecture. Recently service-oriented architecture is a research hot because it is open and flexible. But all people only concern its application in a certain field. Almost no one puts forward a general method for various field systems. Also there are no service-oriented developing software and tools. This paper proposes a service-orientation solution to the management information system based on SOA (Service-oriented architecture). Business process can be designed by interactive interface library. Users can complete the design of system by simply dragging the mouse. For various systems it is an efficient method because business process can be designed by interactive interface.

Abstract: This work studied the situation of today’s data integration. To better solve the complexity and diversity in data integration, we propose a new idea of data integration service platform based on SaaS. The model architecture of data integration and its work principles are introduced. In the platform source data and result data are two interface.in the form of service. In the data integration platform, data are filtered and combined. the data are produced by the users’ requirements. Users call SaaS service to get the data that they wanted. Finally we analyze the model’s characters. This model of platform is more intelligent, efficient and personalized in solving complicate data integration.

Abstract: Agricultural expert consultation and decision system is an important technology for the development of precision agriculture. But current agricultural expert system of consultation and decision is mostly based on static knowledge, and it can not be dynamically updated. The system is low universal and difficult to the rural application. To solve these problems, the smart phone was used as the carrying platform with expert system, which was built together with computer. Smart phone, which embedded with agricultural expert decision system, is a carrying terminal to provide cloud services, communicating with computer and mobile network. All of the management process, greenhouse environment control, expert consultation, diagnosis of disease and other functions can be implemented by this system. The agricultural expert consultation and decision system is distributive, collaborative, portable, universal and dynamic update. It can really be applied to the agricultural production with high benefit.

Abstract: We used the principle of hyperlink analysis method to mine the website data according to the indicators of the hyperlink analysis. We selected Taobao.com as an object of study. The evaluation indicators of network marketing effect were page views, sales quantity, sales, the number of adding store to bookmark . According to our research, we find Taobao.com stores can use data mining tool to obtain the very good marketing effect.

Abstract: The parameters optimization for injection molding based on digital signal processing is gave in this paper. First, design the optimization program of injection molding parameters with orthogonal test; Second, gating system, cooling systems and related injection molding process parameters are chosen as the experimental analysis factors to optimize injection molding process, and analyze the range and variance of test data by MATLAB, to determine the factors that affect the forming quality of the process significantly; Third, the model of process optimization is established by regression analysis; Finally, the optimal process parameters is found by genetic algorithm. The experimental results shown this optimization method can achieved the best parameters for practical produce. So, the method has important practical significance.

Abstract: A numerical method for modeling equivalent electrical conductivity of closed-cell aluminum foams material based on CST software has been presented. The equivalent electrical conductivity is calculated through summing up the total loss produced in the multicomponent aluminum foams model which has been analyzed by the CST software. The influences of porosity on the electrical conductivities are investigated numerically and the mathematical formulas of the relationship between porosity and conductivity are also shown. The validity of the proposed model was verified through applications of the model in many practical problems, where excellent agreement between measured and calculated results was obtained.
