After optimizing filter back projection (FBP) algorithm of CT with the theory of symmetric transformation group and based on the fact that regular hexagons have the most symmetry axis among all the regular polygons which could pave the two dimensional plane without chink (total six symmetry axis compare three of regular triangle and four of square), a fast reconstruction algorithm is founded to reduce calculating time cost in the back projection part of FBP. Since the back projection part is the major time-consuming part of FBP, the new algorithm accelerates image reconstruction significantly. Compared with the accelerating algorithms appeared recently in the same condition, the reconstruction speed of the proposed method is improved greatly.

The coupling relations of all variables during fermentation process with fermentation are discussed. Since the parameters are always changing as time-varying, nonlinearity and randomicity during biology fermentation control process. the scheme for biology fermentation control process using feed forward decoupling intelligent algorithm for multivariable based on FNN is presented. Fuzzy-Neural controller and decoupling units were designed independently, where the Fuzzy controller combined with neural network and the radial basis function neural network was employed for decoupling. The optimized training algorithm based on the system output error was used for online adjustment of network weights, thus realizing dynamic decoupling, which eliminated the need of identifying the plants. This method, with a simple architecture and a small amount of computation is proved to be effective by simulation and application results.

This paper introduced the concept of Proportional Hazards Model (PHM), it took advantage of the Weibull PHM to establish the failure rate model of transformer maintenance based on condition monitoring information. The failure rate threshold through the maximum availability method was determined, and then the maintenance decision model for the electric transformer was established. Finally, we used a simple case, i.e. an analysis of gases in transformer oil, to illustrate the maintenance decision-making process based on PHM, and to verify the feasibility of this model for the transformer repair.

This paper introduced the control strategy of back-to-back full-scale PWM converter in direct-driven wind power system with PMSG (Permanent Magnetic Synchronous Generator). A simulation model has been built to demonstrate the maximum wind energy capture, DC voltage stability and decouping control of active and reactive power. In addition, the dynamic responses of system parameters during typical voltage sag and the role of dumping load at DC side have been tested. The simulation result shows that direct-driven wind power system has good capability of low voltage ride through.

A method for automatic segmentation of steel bars' image is put forward to solve the counting problems of steel bars in the steel factories at present. The approximate radius of steel bar is measured by chain coding. The edges of steel bars are detected by Sobel operator, and separation of steel bars and background is carried out by Otsu method. Then the improved Hough transformation is adopted in the image of steel bars in order to accumulate the gray values, and the locations of steel bars are got by the threshold segmentation, then max. gray values in a region are founded. After experiments, the accurate counting method of approximate circle images such as steel bars is realized.
