By the use of the Bionic Wavelet Transform and adaptive threshold function, this paper presents an improved wavelet-based speech enhancement method, Adaptive Bionic Wavelet Speech Enhancement. Due to the integration of human auditory system model into the wavelet transform, the main advantage of the proposed method is that the over thresholding of speech segments which is usually occurred in conventional wavelet-based speech enhancement schemes can be avoided. Then it can track the variation of noisy speech without the estimation of the a priori knowledge of SNR. As a consequence, the enhanced speech quality of the proposed method can be increased substantially from those of conventional approaches.

In road traffic, there exists foggy condition very often. The foggy affects traffic efficiency, even leads to traffic accidents. So it is important to measure the visibility in foggy road traffic.With this problem, two foggy estimated algorithms are proposed in this paper. In first algorithm, two iamges are used to estimate visibility togather with Atmospheric Scattering Model.The two image must be in same scene and different weather condition.The second algrithm is used one foggy image to estimate the visibility. But there are two key points in the scene,and these points have similar illuminate property.Experments show that these algrithms are effective.

We present and analyze a model of Opinion Dynamics and Bounded Confidence on the stochastic movement world. There are two mechanisms for interaction. ‘Eyeshot’ limits the set of neighbors around the agent and ‘Bounded Confidence’ chooses the agents to exchange the opinion in the set. Every time step, agent i looks for the agents in its eyeshot and adjusts their opinion based on the algorithm of Bounded Confidence. When the exchange ends, every agent moves itself in a random direction and waits for the next time step. There are three special agents in the model, infector, extremist and leader. The infector is specified as an agent with large eyeshot and the extremist is the agent with high confidence. The leader possesses both high confidence and large eyeshot. We simulated the opinion formation process using the proposed model, results show the system is more realistic than the classic BC model.

The reliability indices of distribution network are practically to reflect the structures and operate characteristics of the whole system. If there are many types of distribution networks need to be assessed, it is very difficult and waste to compute reliability indices repeatedly. In this case, it is very useful to define simple indices to determine distribution network reliability, and avoid terrible computation of indices. In this paper, a self-organizing competition ANN classifier was built to estimate load reliability of distribution network, with redefining indices, which combined reliability and topological structure of distribution network, and reflected the load failure rate. It was helpful to improve the efficiency of network reliability analysis.

Multi-charges exploded synchronously are very useful to improve explosion power. But, there is few of information concerning the peak pressure calculation of two charges' shock wave in present research. The calculation method based on distribution of emitted energy proposed in this paper, considered that under the influence of first charge's emitted energy, the second charge's propagation is changed. Then the correctness of the method has been proved through a series of experiments. Finally, the second charge's peak pressure and its change in entire plane are proposed. This method provides reference information for underwater explosion implement of multi-charges.
