To obtain, understand and evaluate numerous factors of affecting network security with network security situation perception, it can predict the future development tendency, it is a kind of means of analyzing the network security quantitatively, and it is also a fine measurement of network security, studying the situation perception technology has the important meaning. This paper combining visualization...
The network security situation perception technology as active defense technology has become the new research direction of network security field. On the basis of analyzing and summarizing the basic concept and the model of network security situation perception, put forward a method of network security situation perception based on artificial life. This method builds an artificial life model which...
The gas outburst forecasts model is brought forward in this paper. Firstly, rough set requires discrimination data, considering distributed information of class, and continual condition attributes are discredited adopting information entropy theory. On the basis of that, redundancy attributes are eliminated using rough set reduction algorithm. Reduction attributes and rules are gained. Finally, through...
Modular design is a systematic design method, which needs modeling technology to prepare framework for construction and evolution of product system. In this paper, a multi-view modeling methodology is proposed to prepare such an structure for correlation's evolution of product family based on relationship constraint network. According to evolutionary process of modular design, demands of modeling...
Lever-arm effect and flexure are the major error factors for transfer alignment of carrier aircraft's INS which affect the speed and accuracy of transfer alignment. The conditional compensation method of lever-arm effect is directly compensated according to the value which is gotten from calculation with the angular velocity and angular acceleration with lever-arm length under thinking the lever-arm...
