In order to solve the problem of nonlinear maneuvering target tracking, a new cubature kalman filter (CKF) with constant acceleration model was researched. According to simulation result, CKF presented a problem of excessive delay when tracking maneuvering targets with fierce change on acceleration. In order to solve this problem, a backward iterative algorithm that amend the last state estimation with the predicted current state was applied in CKF (BI-CKF). By the end of this paper, a typical target model with turning maneuvering was applied to CKF and BI-CKF, the effect of the two algorithm were compared. The simulation results show that BI-CKF algorithm was better than CKF algorithm at dynamic characteristic.

Content-Centric network is a new network architecture which proposed to accommodate future changes in network traffic patterns, and to acquire the native support for scalable and efficient content. Content caching mechanism is one of the key research issues. It is too concentrated in selecting caching nodes of existing mechanisms, serious uneven with cache load distribution, greatly reducing the systems cache performance and utilization of network resources. This paper presents a cooperative caching mechanism based on cache migration, to ensure that the contents is in more important nodes with consideration the centrality as much as possible. At the same time, when the pressure in the cache is too large, it could select the appropriate neighbor node to metastasize cached content through the available buffer space, cache replacement rate and the stability of network connection and so on. The simulation results show that this mechanism can improve the cache hit rate and resource utilization.

Medical activities produce a huge amounts of medical data which include a large number of redundant data. Feature selection is an effective method to remove the redundant data. Selecting the feature attributes needs to determine a threshold. Currently, the thresholding value is mainly set by one's determination manually, which may lead to inaccurate threshold. In this paper proposes forward an adaptive threshold method combining Bhattacharyya distance and support vector machines (SVM). The experimental results show that the proposed method not only makes a high credibility threshold, but also improves classification work efficiency.
