We propose a novel scheme, called Cooperative Semantic Caching Scheme (CSCS) for multi-level super-peer networks that support hierarchical P2P architecture. Peers share information according the semantic proximity between peers and between shared files to self-organise into clustered groups. In this paper we tackle the problem of exploiting the semantic locality of peer requests to improve the performance of a P2P network by the use of cooperative semantic caches. Such caches group together peers with similar interests as well as files with similar request patterns. Simulation experiments show that the CSCS mechanism achieves significant improvements in terms of access latency and global cache hit ratio.

Emotion recognition from Electrocardiography (ECG) signal has become an important research topic in the field of affective computing. In the current work, ECG signals from multiple subjects were collected when film clips shown to them, and then feature sets were extracted from precise location of P-QRS-T wave by continuous wavelet transform (CWT). Hybrid Particle Swarm Optimization (HPSO) was utilized for feature selection, whose discrimination criteria was the correct rate of fisher classifier and the number of features selected. For recognizing two emotions of joy and sadness, effective features and better recognition rate were obviously obtained. Experimental results indicate that the features that acquired from experimental simulation can represent the changes of emotions, HPSO and fisher classifier are effective ways for emotion recognition.

The traditional algorithm for smoothing fingerprint orientation fields was based on the low-pass filter. To improve this algorithm, a variable window adaptive smoothing algorithm for the fingerprint orientation fields is proposed based on the fingerprint orientation consistency. Our algorithm uses the correctness of the fingerprint orientation field to compute the weighted average of the orientation field. Experiments show that our algorithm can effectively deal with the orientation field images which have noises and really describe the topological structure of the fingerprint ridge.

In designing new wells, hydrogeologic operators often make a rough estimation through drawing lines method, according to stratum, aquifer and electric measuring curve of reference wells. This method can not meet the requirement of imprecise for its insufficiency of utilizing data of reference wells. How to analyze the distribution of stratums and aquifers of new well has become a serious problem to be solved urgently in groundwater management. This paper tries to make full use of GIS capacity of data management and strong analysis and the Piecewise Bilinear Interpolation theory to get the aquifer distribution in designing new well and show Cross-section of new well. First, designing database, including graphics database and hydrogeological database. Secondly, according to different wells, choosing reference wells and forming the section graphics of reference wells. From these graphics, the stratum and aquifer of reference wells is displayed. Thirdly, Piecewise Bilinear Interpolation theory is applied to calculate the stratum and aquifer position of new well. The new method shows its advantages in higher precision and efficiency.
