This paper proposes a safeguarded formation control algorithm for a position - velocity safeguarded formation control system using multi-agent theory. In our study, based on artificial potential approach, we present a distributed safeguarded formation control algorithm. It is guaranteed that the system asymptotically converges to the pre-specified safeguarded formation on the effect of the control. And it can be proved that during achieving the objective, collisions among the members in the formation are avoided. © 2014 IEEE. Source

Aimed to the difficult problem of detection information of video advertising from the massive video data, the novelty detection method of the video advertising based on the least squares support vector machine (LS-SVM) algorithm is introduced after analyzing and studying the feature of video advertising. The detection of the abrupt change shot and the gradual change shot in video data is realized by using color histogram algorithm, and the classification of the shot is achieved by using the particle swarm optimization and least squares support vector machine algorithm. The experiments show that the method based on the color histogram algorithm and LS-SVM algorithm has better Precision and recall, and can realize the accuracy detection of the video advertising. © 2015 SERSC.

In the background of aeronautical anti-submarine, the search range models of multistatic sonar, aircraft associated search models of dipping sonar and buoys, submarine moving models were built. Based on those models, the influence of the varieties of submarine initialization courses, sea environment noises, search manners in the experimentation was simulated and analyzed. The results show that it can save search time and improve search probability using multistatic aeronautical sonars composed of dipping sonar and buoys. And the factor of submarine initialization course had a litter effect on the aircraft associated search of dipping sonar and buoys, the factor of sea environment noises had a great effect on it.

X ray film is usually used for detecting the crack of the metal in the industry field, but it is inefficient and fallible for men to distinguish the crack from the noise background if the number of the X ray film is so many. In this paper, a very applied method based on the matched filtering is proposed. To realize the method, matched filtering the origin image, and then edge detecting. In order to realize the effect of the method , the crack will be measured and the edge of the crack will be marked with red color. According to the simulation, the method is feasible and reliable. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE). Source

Along with the change of troop's assignment and the mode of missile equipments' application, the work of deployed equipment's logistics support has changed a lot. Supportability demonstration also becomes an important job in the course of the missile equipments' developing, manufacture and deployment, and it has become the foundation of the missile materiel's research about Integrated Logistics Support. In this paper, studying on the trade off standard of missile equipments' supportability, and analyzing the support of combat mission and drill mission. Then EPC based model is built. All these works is done for offering some reference about the missile equipment's support planning. © 2011 IEEE. Source
