In order to improve the quality of graduate dissertation and examine the quality of graduate education, the mechanism of graduate dissertation random inspection evaluation in Shanghai has been operated for more than ten years. Evaluation experts evaluate the quality of dissertation by using subitem evaluation method rather than comprehensive evaluation method to reduce the risk of misjudgment. Decision...
E-Learning is widely accepted to be the next generation of learning approach with extended features, while technology and theory step forward. However, the current model of e-Learning system lacks the scalable and sustainable infrastructure to support extended features. In this paper, we discuss the technical challenges faced in e-Learning and some common problems concerned by content providers. After...
Domain Name System is the most widely used protocol for domain name resolution in the Internet. Domain name resolution is necessary for most of Internet services and it is usually provided by DNS full resolvers. Unfortunately, many reports indicated that DNS protocol was also used in botnet communication recently. Botnet communications between bot-infected computers and Command and Control (C&C)...
Recent reports on Internet security have indicated that the DNS (Domain Name System) protocol is being used for botnet communication in various botnets; in particular, botnet communication based on DNS TXT record type has been observed as a new technique in some botnet-based cyber attacks. One of the most fundamental Internet protocols, the DNS protocol is used for basic name resolution as well as...
The attempts of malicious access and attacks from the Internet to the internal computers of organizations never stop today and corresponding countermeasure for each technique is required. Most organizations introduce some firewall facilities as one of the solutions to protect their internal computers as well networks from those attacks. However, in most organizations, the network administrator has...
In this paper, we propose a reversible data hiding method based on pixel difference histogram shifting and ripple strategy. Because the local area has similar pixel value distribution in the natural image, the pixel differences will be narrowed down within a small range. The ripple strategy is used to calculate the pixel difference using the pixels in the outer ripple to subtract the pixels in the...
Surveillance cameras account for a large portion of the security devices market and are used in an increasing number of areas. Recently, surveillance cameras have been evolved into high performance intelligent surveillance camera systems using many image processing algorithms including face and object recognition, image reconstruction, super resolution, and tracking. Most image processing algorithms...
Computer-games research has opened a door to a multi-discipline domain across artificial intelligence, computer-aided design and computer graphics. Chinese chess is one of the most popular board games worldwide and many researches on move generation, position evaluation, searching, opening and endgame play, have been developed. However, few work has been done in the basic representation of Chinese...
