In order to increase the accuracy of abnormal event detection in crowd video surveillance, this paper proposes a novel hybrid optimization of feature selection and support vector machine (SVM) training model based on genetic algorithm. For reducing dimensions of multi-feature, we propose an adaptive genetic simulated annealing algorithm (ASAGA) feature selection method. The ASAGA takes advantage of the local search ability of simulated annealing algorithm (SA) to solve the slow convergence and high complexity drawbacks of genetic algorithm (GA). And also improve the SVM training model performance based on genetic algorithm. Experimental results demonstrate that the proposed hybrid optimization based on genetic algorithms can quickly obtain the optimal feature subset and SVM parameters. Therefore the proposed scheme reduces time and improves the accuracy of surveillance video anomaly detection.

Due to the fluctuation and intermittency of wind power, it is necessary for power systems to provide flexible power to ensure the power balance of supply and demand. Meanwhile, as the increasing installed capacity of wind power, more flexible power is required, and the amount would be significant and the balancing cost would be more expensive. In this paper, the balancing cost is calculated from the viewpoint of economic dispatch, which is the difference between the total power system costs with and without wind power. For the case without wind power, an energy proxy is proposed to replace it, which does not need other resources to balance. The result shows that the balancing cost is increasing with the increase of penetration and volatility of wind power.

Based on the analysis of user behavior in social network, knowledge is introduced into social subject's behavior and explores the online social network public opinion research in the related method. First of all, based on the multi-dimensional social relationship between the users participating subject discussion, two-layer overlay network model of topic keywords with the user based on implicit link is put forward targeting at the problem of short text and semantic sparse in a new generation of online social network represented by Weibo system. The model takes the user as the center, the keyword as the basic unit, and applies the clustering method. The model can be used on the real data sets to show that all kinds of important users and user groups of the hot topics, and discuss different users and user group of the topics of concern in the form of a keyword to. It is found that the same role in different groups of users have different motives in the real social network. These findings have important practical significance for discovery and control of public opinion in the social network systems.

In this paper, the effect of different reflective surface and unequal transmitter and receiver antenna height on channel characteristics of the hexapolarized multiple input multiple output (HMIMO) system are investigated, by establishing HMIMO communication channel model. In a simplified reflected channel, we select three different reflected surfaces and compute their channel eigenvalues and channel capacity, respectively. Computation results show that the relative dielectric constant of reflected surface is a main factor which impacts the channel capacity of HMIMO system, as the relative dielectric constant becomes big, the channel capacity becomes small. In perfect electric conducting (PEC) ground reflected channel, the different receiver antenna height is studied. It suggests that the channel capacity will increase with the increase of the receiver antenna height.
