Flight safety at both high and low altitude airspace become more and more important in the recent years. In this paper, considering the free flight characteristic of aircrafts in airspace, a decentralized approach based on satisficing game theory is proposed. This method can eliminate conflicts among aircrafts effectively, and it can also solve collisions with obstacles which mainly include the special use airspace (SUA), severe weather regions in high altitude airspace, and obstacles in low altitude airspace. The simulations show good performance in a complex scenario, which includes a large number of aircrafts flying through a airspace with obstacles at the same time.

The moving object detection is a prerequisite and difficult point to realize tracking in the video tracking system. In order to detect moving object effectively, an object tracking algorithm is proposed based on combination of dynamic template matching and Kalman filter. First, get the area of the moving object by using inter-frame difference method and extract the SIFT feature points. Then, find the location of the candidate object that is most matched with the object template in the search area by Kalman filter and match it with the object template in the current frame. Finally, the feature points' loss rate will serve as the limited threshold, and we update template according to dynamic template updating strategy. By the number of the frames of the target's matching failures we determine whether the moving target is disappeared. Several experiments of the object tracking show that the approach is accurate and fast, and it has a better robust performance during the attitude changing, the size changing and the shelter instance.

The instability of Magneto Hydrodynamics (MHD) in tokamak plasma is a main factor in deciding high performance operation of the device. The occurrence of MHD instability will lead to deterioration of plasma confinement and even split of plasma discharge in severe instance, which can poke potential risk of damage to the device and its work staff. This paper presents a HT-7 MHD real-time detection system based on Radial Basis Probabilistic Neural Networks (RBPNN). The article firstly expands on measurement of MHD in HT-7 and corresponding character analysis of it. According to the signal frequency of MHD, RBFNN training samples can be constructed via mass data acquired through repeated discharges and thus completes the task of sample training. During the discharge, high speed data acquisition board DAQ2010 with double buffer is used to finish the job of real-time data acquisition while the trained RBPNN works spontaneously to process MHD signal. Repeated Tokamak discharges proved the effectiveness of the method described above.

This paper proposed a new method for extracting visualness attributes (the extent to which an attribute can be perceived visually) that based on conceptual graphs (CGs). By providing a small scale seed attributes, this method acquire the context which contain these seed attributes by two steps, primary entity matching and sentence selection, then transform the selected sentences into CG templates, after systematic expansion of its semantic information on the basis of HowNet lexicon, extract the attribute concepts by computing the similarity between CG templates and textual CGs, then compute the visualness of these attribute concepts and retain the attributes with the visualness value greater than the threshold. At last, we construct the relationship among the attributes by bringing in world knowledge. Experiments have demonstrated the effectiveness of our conceptual graph based method when compared with the state of art ones.

In view of the low efficiency of depending on one extracting method, this paper proposes a blending extracting method based on the combination of statistics, regulations and managing nature language. By employing template construction to extract conceptual relations, this method adopts transfer learning to obtain concept pairs and by using the advantages of concept graph in knowledge representation, matches templates through conjoining the Hownet in order to gain template set and extract conceptual relations. The experimental results show that this method can raise the accuracy rate in relation extraction.

A new epsilon constrained biogeography-based optimization is proposed to solve constrained optimization problems. In the proposed algorithm, the epsilon constrained method is utilized to handle the constraints. Simultaneously, based on the feature of epsilon constrained method, a new ordering rule based on epsilon constrained is used to obtain the immigration rate and emigration rate. Additionally, a new dynamic migration strategy is shown to enhance the search ability of migration mechanism. Eventually, with the purpose of improving the precision of convergence, the piecewise logistic chaotic map is introduced to improve the variation mechanism. Numerical experiments on 13 well-known benchmark test function have shown that the proposed algorithm is competitive with other optimization algorithms. Furthermore, the proposed algorithm can avoid effectively the convergence before the optimal results have been found, and balance the exploitation and the exploration.

Non-photorealistic rendering (NPR) such as stylization has received much concern in area of computer graphics and image processing. In this paper, a simple and effective method is proposed for streamline stylization. Through a kind of sequential filters, the method performs a series of operations, including detail removal, region smoothing, structure enhancement, and edge sharpen, to transform common pictures into Impressionist oil-painting like images with streamline style. Experimental results on a gallery of images demonstrate that our method can render images in good NPR style impressively and provide encouraging visual effects.

In this paper, we propose one adaptive pinning synchronization scheme in complex dynamical networks, whose adaptive law is simple in form. When a nonlinear vector field meets different conditions, we prove that the scheme is synchronous and that the synchronous solution is locally and globally asymptotically stabile. We analyze the process of using maximum eigenvalues of low matrix to judge pinning synchronization, and give one method to calculate the number of pinning nodes. At last, three numerical simulations are given to verify the effectiveness of the proposed scheme. The first two examples show relations between maximum eigenvalues of the principal submatriecs and the number of pinning nodes under the conditions of three pinning strategies in a scale-free network and under the conditions of the random pinning strategy in a nearest-neighbor network, respectively, and the last one shows effectiveness of the adaptive pinning synchronization by selecting pinning nodes randomly in a scale-free network.
