In the intra coding of HEVC/H.265, the computational complexity of intra mode decision is very high because up to 35 intra prediction modes are supported. Though a fast intra mode decision based on rough mode decision (RMD) is adopted in reference software HM12.0, only a fixed number of intra modes are selected for rate distortion optimization (RDO). In this paper, an adaptive fast intra mode decision...
Software vulnerabilities are one of the root causes of network security issues. Software security testing is an essential part of secure software development. Fuzzing has been proven to be an effective dynamic software security testing method. In this paper we present a guided fuzzing approach based on dynamic taint analysis for security testing of network protocol software. This approach identifies...
Software Defined Networking (SDN) is an emerging networking paradigm which intends to merge networks into the age of the cloud, providing fine-grained control, simplified configurations, unprecedented flexibility and seamless scalability. However, due to the large set of unresolved challenges as well as the deployment cost, network evolution to fully SDN systems will take a long time. In fact, SDN...
Software security has become a very import part of information security in recent years. Fuzzing has proven successful in finding software vulnerabilities which are one major cause of information security incidents. However, the efficiency of traditional fuzz testing tools is usually very poor due to the blindness of test generation. In this paper, we present Sword, an automatic fuzzing system for...
In order to meet the requirement of the real-time data surveying of land utilization, an efficacious land survey GPS handset system was presented in this paper. In the system, a design pattern based framework was given out to increase its reusability, flexility and maintainability of Embedding GIS. Encapsulation for command like actions by applying COMMAND pattern was proposed for the problem of complex...
We investigated the current curriculum and the laboratory teaching of The Capital University of Economics and Business with a focus on those of the industrial engineering department. Concerning the existing difficulties of fewer laboratory teachings for students in non science/engineering majors and inefficient sharing of the resources within the science/engineering departments, we propose to construct...
A real time network is introduced to the development of a test system of SINS/GPS (ship's inertial navigation system/Global Position System) integrated navigation system. Because only the three-axis angular motions can but the three-axis linear motions can't be emulated by three-axis revolving table, the complete navigation computing is accomplished by external compensation of linear motions. A navigation...
Recent advances in wireless networking technologies and mobile computing devices have engendered a new paradigm of computing, mobile computing. In the meantime, applications on these mobile devices also present some challenges to software designers. In order to cope with these challenges, many research efforts have been focused on a new middleware system that can support the requirements imposed by...
