As the rapid development of social media, now massive data are produced every day. We need to know about users' view and comment on a hot event so that the government and relevant departments can control and guide public opinion, and people can have a correct understanding of the event. So it is necessary to analyze these data. While it is difficult to dig out sufficient information from these data...
In order to meet the overwhelming demands of content retrieval for mobile end users, the community effort has been made on designing next-generation Internet from a clean slate. In this paper, we present the design and performance evaluation of Integrated Caching, in which we assume each router on the Internet can cache contents that pass by and reply to content requests with its local copy. This...
With the development of Internet, the increasing volume of information posted on micro-blogging sites like Twitter necessitates the need for efficient information filtering. In conventional text classification problems, it is assumed that the feature vectors extracted from the available documents are sufficient to learn good classifiers. However, this conventional approach is not likely to work for...
The tamper-proof of web pages schemes mainly includes two aspects, one is the generation algorithm on pre-embedded watermarking, and the other is the program on the watermarking embedded. In this paper, a novel web page watermark scheme is proposed for detecting and locating tampered web-page. Proposed scheme realize the location of the target HTML page tampered. PCA digital watermarking and ULC (Upper-Lower...
In order to meet the overwhelming demands of content retrieval for mobile end users, a novel architecture for the next-generation Internet called Cache-and-Forward (CNF) has been proposed to transport content as large packages in a hop by hop manner towards the destination, instead of transporting a stream of small packets along an established TCP/IP connection. In this paper, we investigate how CNF...
In this paper we discuss the strategy behind and implementation of the joint engineering degree programmes offered by Beijing University of Posts and Telecommunications (BUPT) and Queen Mary, University of London (QM). These programmes, taught exclusively in English and entirely in Beijing lead to students gaining a degree from each university; they are also the only degree programmes of this kind...
In this paper, a robotic machine with 3 degrees of freedom (DOF) is proposed. First, the geometric structure of the 3-DOF parallel robot is presented; in the mechanism, a fourth kinematic link -a passive link connecting the base center to the moving platform center -is introduced. This last link is used to constrain the motion of the moving platform to only 3-DOF. Then, the kinematic and dynamic models...
