Research on Tension Distributed Characteristic of Scraper Chain based on State Observer by Xing Zhang, Fan Jiang, Chenxi Jia, Yutan Li, Chuanjin Zhang

“…Aiming at the structural complexity of chain drive system and the difficulty in tension distribution analysis of the scraper chain，the tension distributed characteristics of the scraper chain are studied based on the design of state observer.A chain-drive virtual prototype model is constructed by the Adams simulation software，and the discrete mathematical model of the chain drive system is then established based on the finite element analysis.Through design of the state observer，the estimation of tension distribution of the scraper chains is accomplished，so as to provide an effective basis for the operation status assessment of the scraper conveyor.…”

New approach to evaluate the capacity of signature-based intrusion detection systems by SUN Mei-feng1, GONG Jian1, YANG Wang1

“…For improving the accuracy of IDS evaluation,after the detection method of signature-based IDS was analyzed,pointed out that the current methods are not reasonable,and proposed the principle to evaluate the capability of IDS im-plementation and the capability of rule base respectively.The method to evaluate the capability of IDS implementation,which views the human knowledge as parameters,was introduced.The definition of metrics and how to calculate the value of metrics are mainly discussed.A prototype was implemented which shows that this new method can evaluate the real capacity better for a signature-based IDS.…”

Differential data update scheme on network-coding-based cloud storage system by Long-jiang WANG, Yue CHEN, Xin-cheng YAN, Kai-xiang HUANG

“…In order to solve the problem that the communication overhead of date update was too large on network-coding-based cloud storage system,a new differential data update scheme was proposed.By encoding and compressing the updated part of file,the communication overhead was reduced significantly.A network-coding-based storage prototype system was designed and implemented,and update scheme was deployed in the real network settings.Experimental results show that the proposed scheme has less communication overhead and better scalability than the existing schemes.…”
