There will be lots of complicated stochastic problems in any mine-sweeping fight, and it is difficult even impossible to evaluate it and present its solution which is based on deterministic method. However, to find a key to solve the problem related to estimation of mine area status is very important, especially without some necessary parameters, such as working condition of mine, sweeping probability, maxcount of mine etc. In this article, a scientific model founded on Monte Carlo simulations and Markov process was put forward, its validity was tested and verified by means of emulation.

Warfare simulation needs to render a realistic virtual 3D battlefield environment efficiently to ensure the authenticity and real-time interaction. However, modeling special phenomena which are common in battlefield environment has proved difficult with the existing techniques of computer graphics. A method for special effect modeling and simulation by using particle system is proposed. Based on detailed discussion on the theory of particle system, the general particle system model for special effect simulation is designed, and its concrete implementation is presented. By capturing common features of various effects and carefully structuring into the model composition, the model can be reuse in different effects simulation with little modification, making it an efficient way to create various convincing special effects in virtual battlefield environment. With its flexibility, the model is easy to manipulate and implement. Its Level of Detail can be easily adjusted. Finally, concrete special effects simulation examples by using the model are also given to test its efficiency. ©2010 IEEE. Source

It is hard to estimating effect without some necessary parameters such as working condition of mine, sweeping probability etc. This article designed an improved model which is based on Markov chains in consideration of some special situations, for example, if the mine field is swept one time, some mines can be affected many times. After analyzing the constraints of the model, we investigate the solving method for the model: stepwise regression and genetic algorithm. At last the emulation is carried out to demonstrate the calculation of the effectiveness indexes with relative analysis. The result shows that the estimating model can get exact outline of mines even in the condition of small sample data. Source

As the next generation video display technique after 2D display based on DTV/HDTV, multi-view autostereoscopic three-dimensional (3D) display has been one of the most popular research issues in the world. And 3D displays are classified into two types: stereoscopic 3D display and autostereoscopic 3D display. The former includes head mount system, anaglyph system, polarized filter system, field sequential system and so on. The latter is also called true 3D display, it provides 3D perception without the need for special glasses or other head gear. In this paper we research on the multi-view autostereoscopic 3D display. Focusing on the multi-view stereoscopic 3D key technologies, the latest international development trends and existing problems is analyzed. Meanwhile a solution for implementing we designed an autostereoscopic multi-view 3D display that has pivot function in this 3D display several viewers without wearing eyeglass can see 3D stereo images on the prototype of the display. © 2010 IEEE.

This paper presents a novel approach towards showing how contractor in agent-based simulation for complex warfare system such as multi-sensor battlefield reconnaissance system can be selected in Contract Net Protocol (CNP) with high efficiency. We first analyze agent and agent-based simulation framework, CNP and collaborators, and present agents interaction chain used to actualize CNP and establish agents trust network. We then obtain contractor's importance weight and dynamic trust by presenting fuzzy similarity-based algorithm and trust modifying algorithm, thus we propose contractor selecting approach based on maximum dynamic integrative trust. We validate the feasibility and capability of this approach by implementing simulation, analyzing compared results and checking the model. © 2012 Copyright the authors. Source
