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.

Through analyzing the theoretical basis and approach features of system-of-systems and cloud computing technology, the designing infrastructure and application flow of the meta-synthetic environment for equipment system-of-systems demonstration have been given with a combination of construction and application requirements of equipment system-of-systems centered on information. When designing the meta-synthetic environment for equipment system-of-systems demonstration, we adopted the way of Service Oriented Architecture (SOA), and put forward a model registration mechanism. By establishing the model registration principle, we designed and generated the model registration system, realized the model registration and management of the meta-synthetic environment to solve the quantification and evaluation issue and realized Design on Demand and Service on Demand of evaluation of the equipment system-of-systems demonstration meta-synthetic environment.

In order to resolve the problems resulting from various combinations of equipment selection, numerous uncertainties of future demands and the development process, a planning method based on the Markowitz model is proposed. First a qualitative analysis is performed and models of a combination planning method are produced, then a Markowitz model of the development plan of system-of-systems under uncertainty is built and solved by adopting a searching algorithm based on vector operation. Finally the effectiveness of the method is checked by scouting the development planning examples of the early warning surveillance system.
