Abstract: In order to improve applied-information technology in supply chain collaborative system, it proposes a method of supply chain knowledge collaboration based on semantic Web service. Specific research process is as follows. Firstly, the Web knowledge service ontology based on OWL-S supply chain is introduced, and then analyzed the semantic Web service in the supply chain, three different type models of supply chain knowledge collaboration are also proposed from the standpoint of knowledge system construction, finally, the system structure of supply chain knowledge collaboration based on ontology is designed. The results show that using the model paper mentioned can improve the overall system performance of applied-information technology efficiently.

Abstract: This paper applied information technology and takes the exploratory action or state transfer formed experiences of control system as the basis, in the unsupervised condition obtaining planning and controlling rules from experiences as the control knowledge. In learning process, experiences will deduce to rules, then generate high-level concepts or rules, constitute multi-resolution knowledge architecture. In the experiment, mobile robot effective learning and planning system state and action control in quasi-optimal manner based with random experiences.

Abstract: The canvas in the HTML5 provides very powerful ability to realize complex graphics and image operations. It can be used for developing information application about graphics such as chart module, scientific computing visualization, drawing software, animation system and information visualization and so on. It will play an important role in the web game for PC or mobile platform because the HTML5 has the platform-independent feature. In this paper a system of graphics algorithm presentation is provided and it uses the prototype object and image data structure of canvas rendering context 2D model to define the custom function to implement the graphics algorithm. It demonstrates the realization process of the principle of graphics algorithms and it shows that the canvas has great flexibility and scalability characteristics.

Abstract: Particle swarm algorithm has been proven to be very good solving many global optimization problems. Firstly we improved particle swarm optimization algorithm, the improved PSO algorithm for continuous optimization problem, in solving the nonlinear combinatorial optimization problems and mixed integer nonlinear optimization problems is very effective. This design adopts the improved particle swarm algorithm to optimize the PID parameters of the control system, and the effectiveness of the improved algorithm is proved by experiment.

Abstract: Sandy conglomerate reservoir has the characteristics of poor sorting, complex pore structure, heterogeneity, and so sandy conglomerate oil layer is difficult to identify. In this paper, based on symmetrical effective medium conductance theory and poor sorting of grains of sandy conglomerate, a symmetrical effective medium resistivity model for sandy conglomerate reservoir is established by dividing sandy conglomerate reservoir into three components, including a non-conductive matrix, gas and water. The log data is processed and interpreted with the proposed model, and the interpretation result compared with gas production test data. It shows that the model is applicable to evaluate the fluid property of sandy conglomerate reservoirs.

Abstract: The paper introduced image processing technology based on image segmentation about on-line threads images, and describes in detail image processing technology from image preprocessing, image gmentation,and threaded parameter test. Threaded images of on-line processing parts obtained are introduced as the key technology, Target edge extraction process from the segmented image are also recounted. At last, this article shows a comparison between actual machining parameters of screw thread and the standard parameter , provides the criterion for error compensation.

Abstract: Power system storm disaster risk assessment need to simulate the storm scene, the storm induced electric field is one of the key places. Spatial and temporal distribution model of electronic technology is proposed to establish an electric field and magnetic storms inductively for 7-9 November 2004 geomagnetic storm scenario simulated observational data, and integration with the power system, as an application of the GIC were considered the standard case model risk analysis system running under the impact of the storm. Numerical results show that the electronic materials model can effectively simulate the storm scene and can easily be combined with the power system parameters.

Abstract: Computer simulation technology is a very complicated professional technology, data acquisition system using data acquisition card generally is expensive and difficult to exactly match with the actual demand. Sound card as the data acquisition card has the advantages of low cost, easy development and system flexibility. Is studied based on the model of activity of simulation technology, the concept of modern simulation methodology of system modeling method, simulation modeling method and simulation experiment, the simulation modeling of the commonly used algorithms and relevant issues, the simulation credibility concept and research content. In recent years, with the rapid development of information processing technology, simulation technology is rapid development. According to the author's research experience, this article attempts to from the meanings of the simulation, and discussed the modern reliability method, the modeling method, the simulation algorithm, simulation research and so on, to reasonably and effectively in the simulation operation simulation do some exploring new methods and new technologies.
