摘要：
This paper addresses a method of automatic detection of digital audio signal tampering based on feature fusion. Aiming at the insertion and deletion operations in the digital audio signal tamper chain. In this paper, the Electric Network Frequency (ENF) component of the digital audio signal is extracted and the consistency of the ENF component is analyzed to determine whether the audio signal is tampered with. In this paper, a general framework for passive tamper detection of audio signal based on ENF component consistency and a general framework for ENFC feature extraction are proposed. The feature set is used to quantify the amplitude of the phase and instantaneous frequency variations of the ENF component and to serve as an indicator of the consistency of the ENF component. SVM classifier is used to classify the extracted feature sets. The experimental results show that this method can classify the original signal and the edit signal which is inserted and deleted.

摘要：
Interactive Educational Mode which emphasizes various kinds of actions during teaching process is targeted at cultivating students' discovery, analyzing and solving problem, improving autonomous learning ability and fostering the mode of incentive thinking, in a large extent, it embodies the "double-subject" position. However, as a new information technological tool, electronic interactive whiteboard has been concerned by lots of experts and scholars for its powerful interactive function. Therefore, for improving the instructional quality and reforming the educational mode, it has an important significance that how to apply interactive whiteboard to Interactive Classroom Teaching.

摘要：
Nowadays, Internet goes deep into human beings' daily routines and brings us many remarkable conflicts between mass digital information and our limited capabilities of acquiring them. Search engine thus becomes an important channel of obtaining information. But conventional search engines can index less than 16% of the publicly indexable Webs, and the other 84% are "invisible". Moreover, the public information on the Invisible Web is 400-550 times larger than WWW. Thus users are searching only 0.03% of available pages. Therefore, it's urgent to seek efficient methods to solve the retrieval problem of Invisible Web. This thesis elaborates the reasons why Invisible Web is invisible, puts forward several effective strategies of hunting up invisible resources, and expects to bring human beings enlightenment in network information retrieval and utilization.
