Omni-directional wheeled motion system with its flexible steering, stable structure and reliable control precision, become the basis of the mobile robot system which used indoor. In this paper two kinds of Omni-directions platform which wheeled by three Mecanum wheels are built up, by setting up the dynamical simulations about the two model based in simulation software, and according to the dynamic...
The size of the substation is constantly expanding with the development of electric power industry. The substation equipments which are long-term exposure to the outdoor affected by natural and industrial contamination are easily caused the flashover phenomenon. The substation equipment water washing robot with hot-line is used to water cleaning operations carried out on the post insulators in substation...
In this paper, we propose a novel large-scale social network community discovery algorithm based on probabilistic model to organize users with similar interests into a same group. Firstly, the user community discovery problem is illustrated. The large-scale social network can be regarded as a graph, in which edge represents the relationship between two nodes. Therefore, the user community detection...
In this paper, an intelligent development platform based on "one network, four bases and two engines", which can be used to develop a so-called expert system (ES) is proposed. This paper aims to provide a universal, convenient development environment for the expert systems. A four-layer architecture that is closely integrated with the application is presented. Additionally, three service...
Based on the injury estimate system of vehicle occupant in emergency brake is established. The vehicle occupant restraint system model is established based on software called MADYMO for front impact simulation, the system consists of body, safety belts and a dummy. After adjusting the model, occupant head and chest injury curves and injury values such as HIC, T3MS and Thpc are got, which are close...
In this paper, an analysis of the spatial and temporal landscape evolution of northwest Sichuan Province, China, is carried out based on the landscape theory, RS and GIS. Fucheng District in Mianyang City, Sichuan Province, is chosen as our study area, and the driving forces of its landscape evolution are discussed based on the land use maps, the Landsat TM/ETM+ and CBERS 2B remote sensing images...
Intelligence is a very important characteristic for cognitive radios (CR). Design of cognitive engine and application of artificial intelligence (AI) techniques are key to the implementation of this characteristic. Machine learning is one of the disciples in AI. This paper will propose a scheme of cognitive engine design, and use a learning algorithm based on neural network (NN) to implement a learner...
We have proposed the combining evaluation method of grey relational analysis and AHP method, and apply it to the destruction evaluation of airport target. It uses reciprocal judgment matrix to confirm the element weight of scheme measure hierarchy and introduce the triangular fuzzy number complementary judgment matrix to confirm the element weight of rule hierarchy. The evaluation and comprehensive...
Multi-domain unified modeling of complex product and optimization design technology is one integration description methodology, which can describe how to construct the unified modeling of complex product and carry out the synthetical optimization based on various fields. To achieve the seamless integration of unified modeling of complex product and optimization design and realize the system-level...
The development of E-Gov affair needs the support from all sorts of theory and practice urgently. The official information flow processing exists in different levels of governments and enterprises routine official activities broadly. So researching on that is with the great necessity. Firstly, the paper generalizes and analyzes KMpsilas contribution to official businesses. And then, analyzes the problems...
Based on the analysis of fuzzy control, combined with the form of PID control, the S plane control has been applied. For the default that particle swarm optimization (PSO) presents the phenomenon of precocity and getting in local minima, the basic PSO algorithm is improved. Based on the self-adaptive idea, a concept of dynamic learning factor is introduced. This method could improve the coordination...
