This paper proposes an improved cloud-element model for information security risk assessment. Combined with the characteristics of dynamic balance of information security risk, we propose the control means and uncontrollable factors as information security risk evaluation index. The method of constructing the sample cloud has been expatiated, and the correlation between the cloud droplet and the sample...
Electronic seal system is widely applied in actual business activies, giving the architecture and corresponding signature algorithm of Electronic Seal System based on digital watermark Technology. Discusses the steps respectively for digital signature algorithm and digital watermarking algorithm, and explain the nested with Word document in its practical application, At the end of paper, the method's...
In order to analyze safety of traffic accident scenes and avoid secondary accident, influence factors including human factors, vehicle factors, road and environment factors and management factors were analyzed. Based on system dynamic, system causality graph and flowchart of system dynamic were established. Changing input of every factor, importance degree of factors was obtained. Evaluation index...
Shock isolator with minimum settling time (SIMST) is a vital device in military and civil use. At present, the design of SIMST draws a lot of attention. Because one of the indexes of SIMST is time variable other than state variable, there is no computation method given so far, and the design of SIMST mainly depends on experiments. In this paper, genetic algorithm is applied to the design. The genetic...
