The complex land system is the major weapon system of army, which accomplish the manifold mission of army on the land. How to test and evaluation the capability and efficiency of the complex land system in the join operations face lots of problems. The demand and conceptual architecture study of land complex system simulation test is the first problem should to be resolve. So, we need first to analysis the demand and conceptual of complex land system, then, we can develop the simulation test system for land complex system which has architecture combat, semi-physical simulation, and engineer compute ability to meet the requirement of the land complex system simulation test. The major point of this paper is to put forward the conceptual model of the land complex land system test and build the architecture of the simulation test environment.

C4ISR system is the multiplicator of System of Armament systems (SoAS). An analysis method for Contribution Degree of C4ISR system is proposed in the paper. Firstly, Overall-Effect based evaluation method for operational effectiveness of SoAS is introduced. Secondly, Contribution Degree of C4ISR system is defined and experiment flow based on exploratory simulation is designed. On this basis, an analysis method for Contribution Degree of C4ISR system is put forward. Finally, a simulation experiment is executed to prove the effectiveness of the method.
In this paper, we address a critical task, i.e. dangerous object recognition for web surveillance system. Instead of investigating how to define an object is dangerous by analyzing human's activities (e.g. leaving...

In simulation grid, information sharing is very important for the grid units to cooperate with each other effectively and efficiently. In this paper, to resolve the problem of semantic heterogeneity, an ontology-based approach is proposed. In this approach, firstly, the local ontologies are merged into a global ontology based on their similarities. Then, with the merged global ontology, the semantic heterogeneity is resolved by comparing the classes and attributes of the local information source schemas. An example of how to resolve semantic heterogeneity in the E-government simulation grid is presented to illustrate this approach.

Existing frequency-domain-oriented methods of parameter identification for uniform linear motion blur (ULMB) images usually dealt with special scenarios. For example, blur-kernel directions were horizontal or vertical, or degraded images were of foursquare dimension. This excludes those identification methods from being applied to real images, especially to estimate undersized or oversized blur kernels. Pointing against the limitations of blur-kernel identifications, discrete Fourier transform (DFT)-based blur-kernel estimation methods are proposed in this paper. We analyze in depth the Fourier frequency response of generalized ULMB kernels, demonstrate in detail its related phase form and properties thereof, and put forward the concept of quasi-cepstrum. On this basis, methods of estimating ULMB-kernel parameters using amplitude spectrum and quasi-cepstrum are presented, respectively. The quasi-cepstrum-oriented approach increases the identifiable blur-kernel length, up to a maximum of half the diagonal length of the image. Meanwhile, directing toward the image of undersized ULMB, an improved method based on quasi-cepstrum is presented, which ameliorates the identification quality of undersized ULMB kernels. The quasi-cepstrum-oriented approach popularizes and applies the simulation-experiment- focused DFT theory to the estimation of real ULMB images. Compared against the amplitude-spectrum-oriented method, the quasi-cepstrum-oriented approach is more convenient and robust, with lower identification errors and of better noiseimmunity.
