According to the energy yield of wind turbines, a new design method for optimizing wind turbine blades based on the aerodynamics is presented. The design object is the minimum cost of energy which is calculated from the Annual Energy Production (AEP) and the cost of the rotor. The design variables used in the current study are the chord and twist angle. The blade shape parameters and the loads of the blades are considered as the constraints. With the model in this paper, one 2 MW wind turbine rotor is designed. The aerodynamic characteristics of the designed rotor are simulated and plotted. To prove the reliability of the results, the comparison between the designed 2 MW rotor and one existing widely used 2 MW rotor is completed. The rated wind speed is reduced from the 15m/s to 12.8 m/s that displays the designed rotor has high power at the low wind speed. The maximum power coefficient is increased from 0.463 to 0.49 that can effectively improve the annual power generation.

In order to improve the ability to get rid of partial extreme spot and the diversity of population in evolution, the immunity mechanism of IA algorithm is imported into PSO algorithm to form IA-PSO algorithm. For the purpose of raising fault rate and shortening test pattern generation time, CA algorithm is imported into IA-PSO algorithm to form CAIA-PSO algorithm. Finally, adopting single stuck-at fault and using different algorithms to the simulation experiment of test pattern generation for digital integrated circuits, the result of the experiment is that CA-IA-PSO algorithm can solve the problem of test pattern generation more practically and efficiently, especially the bigger digital integrated circuits.

Image restoration is an important research field of image processing. The purpose of image restoration is to improve the observed visual effect of image to make it close to the original image. This paper proposes an image restoration algorithm of smoothness constraints constructed by adaptive fuzzy edge evaluation function. First, image degradation/restoration model is introduced, based on the degradation function to solve the ill-posed problem of image restoration. Then, with the process of iteration, more image details can be detected, while the algorithm adaptively produces a more reasonable smoothness constraints. This algorithm can base on restricted adaptive image restoration algorithm, by increasing the sophistication of weight to improve the recovery of adaptive control capabilities. Finally, an experiment can be conducted to prove the effectiveness and feasibility of the image restoration algorithm proposed in this paper.

The K-means clustering algorithm have played an important role in the data analysis, pattern recognition, image processing, and market research. Classical K-means algorithm randomly selected initial cluster centers, so that the clustering results unstable. In this paper, through deeply study on classical k-means algorithm, we proposed a new K - means algorithm of Clustering based on double attributes of objects. The algorithm is based on the dissimilarity degree matrix which generated by high density set to construct the Huffman tree, and then according to K value to select initial cluster centers points in the Huffman tree, using this method effectively overcomes the defects of classical K-means algorithm for clustering random selection caused the initial cluster centers result unstable defects. In this paper, the new algorithm uses two UCI data sets to validate. The results of experiment show that the new k-means algorithm can choose the initial cluster center of high quality stable, so as to get better clustering results.
