In this paper, based on the three-dimensional finite element model of surface grinding, the finite element analysis was employed to analyze the influence of grinding parameters on grinding force during the machining of SiCp/Al composites using diamond grinding wheel. The results indicate that model can reflect tendency of grinding force. Simulated results are consistent with experimental results. The results will provide a theoretical guidance to optimize for cutting process.

All modern indoor swimming pools have a large volume, the water temperature control system is the serious delay and serious inertia nonlinear system. The traditional PLC control system based on PID controller can not meet the control requirements. This paper presents an integrated control system composed of a fuzzy automatic optimization algorithm and the Smith predictor compensator to adjust the temperature of pool water. Experiments and applications show that the proposed control scheme to solve the serious delay and serious inertia system can achieve good control effect.

Software reliability is a hot issue of software engineering research. In order to improve the prediction accuracy of software reliability's failure data, the researchers introduced the entropy weight to build the combination forecast model on the basis of establishing single forecasting methods. Data simulation results indicate that this method has higher precision of prediction than that of the single forecasting methods, and thus is applicable in certain fields.

Background segmentation is the key step in image processing. The greenness method can satisfy the request of background segmentation of corn crops. Aiming at the different distribution of corn seedling stage in the field, segmentation operator of the greenness method is based on the ratios of R, G and B pixels in the total pixels. By researching on clear and unclear image of distribution between background and vegetation, the segmentation edge is found. By simulation, the greenness method can successfully divide image into background and vegetation.

A tribological analysis scheme for multibody system with clearance joints is presented by integrating frictional contact model, wear calculation with multibody dynamics. Clearance joints are modeled as a continuous contact model with friction. Progressive wear process is simulated by a widely used a finite-element-based iterative scheme. Frictional effect and wear of multibody system can be predicted combining the effects of changing joint clearance and dynamic behaviors. It is shown that maximum slider acceleration increases with friction efficient and wear of the bushing occurs more distinctly in specific zones.

This paper presents an approach based on hybrid particle swarm optimization to solve weapon-target assignment (WTA) problem. The mathematical model of WTA problem is explained in detail. Then the idea of basic particle swarm optimization (PSO) is introduced. A hybrid PSO algorithm (HPSO) is structured by introducing the mutation operator and changing the inertia weight with the generation. The results of simulation indicate that this approach is effective to solve WTA problem.
