Study electroencephalograph (EEG) of epileptic patients during different periods in order to do effective treatments. This paper studies wave forms and energy characteristics of the paroxysmal stage and the static epileptic EEG, adopts two different methods to classify. One is using Support Vector Machines (SVM) to rebuild and classify as to the characteristic signals. The other is applying Empirical Mode Decomposition (EMD) and SVM together to classify EEG. After experimenting and testing the epileptic data, the general discrimination of EEG is 94.5% and 96.05% respectively. The result indicates that using SVM and EMD can achieve more ideal effect, classify the epileptic EEG and normal EEG. Source

Recently, there are some concerns in auction duration and bid arrivals in study of online auctions. In online auctions, seller selects duration, and the bid arrivals pattern is deemed to the indicator of bidding strategies and behaviors of bidders. The best known phenomenon in bid arrival is the late bidding, which describe the following bidding strategy used frequently by many bidders: bidders tends to place bid as late as possible. Noticed there is a void in growing body of literature on online auctions in comparison study of participants' behavior across similar but different websites, we sampled eBay auctions from several global websites simultaneously and compared the duration distributions and bid arrivals patterns across these websites. The statistical results indicate that the comparison study is meaningful. Finally, we imply that more advanced data mining tools are needed in analysis of online auction data in further research. © 2011 IEEE. Source

In this paper, the approximate symmetry reduction for the initial-value problem of perturbed diffusion equations with source term is studied by the approximate generalized conditional symmetry. The classification of governing equations is given, and the Cauchy problem of partial differential equations is reduced to initial-value problem of ordinary differential equations. Finally, the approximate solution is obtained by solving the reduced system of equations. © Chinese Physical Society. Source

According to the effect of fog from images, a new defogging methodfor image based on depth region segmentation is proposed in this paper. This method reasonably applies the fuzzy cluster analysis thinking, Construct the edge characteristic vector based on multiresolution wavelet. It has achieved the depth region segmentation image based on closed boundary of the target object in the scene, thus attaining the effectively enhanced contrast by the equalizing transform of each histogram in the same depth. Experiment results show that this algorithm can efficiently improve the degradation of image and enhance the clearness of image. © 2012 Springer-Verlag GmbH. Source

With the development of our society, great changes have taken place in the way of people's work and life, sports are becoming more and more important. The sport as a part of culture and education, it's value can not be ignored. It can enrich people's life, improve the quality of life, additionally, their have great values in education, fitness and entertainment. Stadium Sports violence is a very troublesome social problem in the current world, to the pursuit of the harmonious development of human society, casting a shadow over the sports. This article will analyze the causes of violence from the sociological point, to provide a theoretical basis to the solution to the problem of violence. © 2011 Springer-Verlag Berlin Heidelberg.
