The involvement of the students determines their study effectiveness, which has influence on the quality of high education in university in turn. In this way, it's necessary to explore the antecedents from the student perspective. Prior research indicates that major commitment influences study engagement significantly. Therefore, we collect the data in eight Chinese business schools to test the above...
E-business has developed quickly in China and China is rich in tourism resources. Compared with other countries, however, the development of tourism e-commerce in China has not developed as well as people had expected. It is worth considering what hinders its development? This paper mainly discusses the hindrances to the development of tourism e-commerce from two aspects. One is analyzed from technical...
A steganographic algorithm for embedding secret bits into uncompressed video sequence was proposed in this paper. The difference between adjacent frames, which is called motion component, indicates the motion of video, and is not obviously affected by video compression. So motion component was used to embed secret bits for increasing the capability of resisting video compression. Motion component...
A discrete three-level food-chain model with Beddington–DeAngelis functional response is investigated. It is shown that the system is permanent under some appropriate conditions.
In this paper, a steganographic algorithm in MPEG compressed video stream was proposed. In each GOP, the control information for to facilitate data extraction was embedded in I frame, in P frames and B frames, the actually transmitted data were repeatedly embedded in motion vectors of macro-blocks that have larger moving speed, for to resist video processing. Data extraction was also performed in...
