In this paper, the Kanade Lucas Tomasi (KLT) feature tracker, which is used in the moving target tracking algorithm, is used in the motion estimation. This method is more accurate and faster than the general feature-based motion estimation method. The basic idea of electronic image stabilization algorithm based on KLT tracking algorithm is to obtain camera motion parameters through tracking feature points, and then carry out motion compensation, so as to obtain a stable display effect.

In order to improve the efficiency, reliability, maintenance ability and expansibility of modeling, the object-oriented method for modeling the 6-DOF (six-degree-of-freedom) simulation system of aero craft is proposed in this paper. UML (Unified Modeling Language) is adopted to model the system. Firstly, from users' view, we analyzed the basic requirements of the simulation system and modeled it by use case diagram. Secondly, from the view of system realization the classes and their relationships are designed. The main events and activities were modeled by sequence diagram simultaneously. Finally, taking the hardware realization into account we established deployment diagram of the system. The simulation result of the trajectory shaping guidance shows that the time consuming of simulation is decreased while guaranteeing the identical of the result. At the same time, the portability, security, reusability, maintainability and modeling efficiency of the simulation system is upgraded.

In order to improve the accuracy of data preprocessing in Web log mining, the basic procedure of data preprocessing is introduced firstly in this paper. Then the traditional session identification algorithm is fully analyzed, on the basis of which, a session identification algorithm based on dynamic timeout is presented. At the beginning of the algorithm, the initial timeout is computed for each page according to the statistical result, combining with the importance degree of page; then during the procedure of session identification, timeout is dynamically adjusted, and user sessions is determined judging by the dynamic timeout. Comparing experiment shows that the algorithm proposed can obtain a better performance on session identification.

As an important part of combat simulation, scenario editor often deals with large quantities of equipment entities and equipment's type, So collaboration editing becomes more and more urgent. When scenario editor deals with different types of scenario data, It also has a bad effect on editing efficiency. The share range must be dynamic changed to enhance the data access efficiency, which stored in storage nodes. Combined with the characteristics of the data and scenario application, this paper gave a share stated adjustment algorithm(SSAA), it can effectively solve above problem.

The algorithm, which avoids drawbacks of conventional approaches, has been presented for not resetable lines using GTL(Global Temporal Logic). This model checking algorithm are subject to constant improvement so that the size of manageable circuits will future increased. In this paper, based on the global temporal logic that defined by forward and reverse operator, a common formal framework for test generation is presented. In addition, heuristic for accelerating the testing process and implementation are given.
