For the current problems in the security situation of colliery equipment ,and based on non-linear relationship among the parameters of colliery equipment ,this paper presents a method for forecasting the safety of colliery equipment based on BP neural network.By using BP neural network in the colliery safety equipment monitoring and warning issues,we established a multi-index comprehensive monitoring...
Coal mine water inrush is a very difficult problems which should be solved more earlier, and it have long plagued safe production of coal mines. The reliable operation of coal mine drainage systems plays a vital role in safe production of coal mines. Based on the non linear relationship of the state parameters of the coal mine drainage facilities, we propose a safety monitoring method based on BP...
In view of the severe situation in coal mine safety production, using tomcat6.0 as the Web server software, through the dynamic web page struts technology and ibatis framework technology to realize database connectivity, using Myeclipse 5.5.1 as a development tool, we develope the web-based system which is monitoring and managing of the coal mine safety equipment intelligently. For different units,...
The system utilizes the object-oriented analysis method and the broad-based B / S / D software architecture. Then researching and developing the coal mining security equipment's intelligent monitoring and management system of being based on the web-environment, the Web server software on this system using the tomcat6.0. Connecting the database by struts and ibatis dynamic web page technology and framework...
Random linear network coding can be used in peer-to- peer networks to increase the efficiency of content distribution and distributed storage. However, these systems are particularly susceptible to Byzantine attacks. We quantify the impact of Byzantine attacks on the coded system by evaluating the probability that a receiver node fails to correctly recover a file. We show that even for a small probability...
Recent research has shown that network coding can be used in content distribution systems to improve the speed of downloads and the robustness of the systems. However, such systems are very vulnerable to attacks by malicious nodes, and we need to have a signature scheme that allows nodes to check the validity of a packet without decoding. In this paper, we propose such a signature scheme for network...
