STRUCTURE OPTIMIZATION OF MICROBRIDGE BASED ON MEMS ULTRASONIC TRANSDUCER by HE JianLong, AN Kun, YANG LiangXing, WANG YaFeng, LIU Jie, MENG Jiang

“…Aimed at the low frequency of traditional ultrasonic transducers in low frequency domain,a new theoretical model of microbridge was designed,with analysis and research of the mechanical behavior. Solid modeling,modal analysis and electrostatic analysis were carried out with COMSOL 5. 4 for the silicon-based microbridges of the antiferroelectric thick film,which can produce the effect of phase-transition induced strain. …”

Method of Webshell detection based on multi-view feature fusion by Feng LIN, Liujing XU, Xiaohua CHEN, Weiqiang QI, Ke CHEN, Tiantian ZHU

“…Webshell is a malicious script file on the Web.It is usually uploaded by the attacker to the target server to achieve the purpose of illegal access control.In order to overcome the shortcoming of the existing Webshell detection methods,such as single network traffic behavior,simple by passed signature comparison,and easily bypassed signature comparison,a method of Webshell detection based on multi-view feature fusion for PHP Webshell detecting was proposed.Firstly,multiple features including lexical features,syntactic features,and abstract features were extracted.Secondly,fisher score was used to sort and filter all features according to the degree of importance.Finally,a model that can effectively distinguish Webshell from normal scripts was established through SVM.The large-scale experiment in real-world scenario shows that the final accuracy of our model can reach 92.1%.…”

CHA: cross-chain based hierarchical architecture for practicable blockchain regulatory by Pujie JING, Liangmin WANG, Xuewen DONG, Yushu ZHANG, Qian WANG, Sohail Muhammad

“…Researching the problems with blockchain regulation is crucial.In view of this, CHA (cross-chain based hierarchical architecture) was proposed to address the problems in blockchain regulatory, and a “chain of custody-business chain” cross-chain collaboration chain-based regulatory model was designed.The decentralized of information system regulatory was improved by building a decentralized governance chain, which realized regulatory by separating the strategy layer from the regulatory layer and the business layer, and achieved separation of regulatory behavior and regulatory technology, thus ensuring the versatility of the blockchain regulatory structure.Finally, the distributed feasibility of the regulatory framework is demonstrated through a formal analysis method, and then the technical feasibility of the scheme in terms of cross-chain regulatory reliability, general feasibility and scalability applicable to different regulatory services are proved.…”
