This paper establishes the index system of the safety evaluation of navigation environment from perspective of which affects the navigation safety. After that, Bayesian network security evaluation method is introduced and the fuzzy set theory is combined to construct a safety state evaluation model. Then the safety condition of the navigation environment is expressed in the form of safety probability.
Security risks brought by web page information has been a matter that can no longer be ignored. Malicious script is a major challenge the web sites security is facing currently. According to the data from the Google Research Centre, more than 10% of web pages is malicious. Especially in China, the proportion of malicious web pages has reached 43.21%. This paper presents a detection system which is...
Coupled Tent Map Lattices system (CML) has made a good combination between confusion and diffusion, which can be well adopted in the design for Hash function and sequential cipher and possesses high value in cryptographic application. Whereas, Coupled Tent Map Lattices system parameters cast a direct influence on cryptographic performance. This paper chooses tent map as the non-linear function of...
Safety producing behavior of construction enterprises is the main step and measure to prevent and control the accidents, and has been in a continuous improvement process. This paper, proposes three stages for the improvement of the safety producing behavior of construction enterprises, systematic studies the external environment and internal economic momentum to improve the safety producing behavior,...
