In this paper we proposed a dictionary learning and dimensionality reduction (DLDR) scheme for image steganalysis. We construct a structural discriminative dictionary which is learned from the reduced dimension space and exploit the discriminative information in stego-images. Simulation results verify the effectiveness of the proposed approach and the performance is considerable. Both the dictionary...
This paper proposes to utilize the latent semantic relations implied by co-occurrence terms in the sample documents, calculate the co-occurrence rate and establish the topic-oriented database of Word Co-occurrence to obtain Biased Summarization. The database is a semantic repository that can be expanded and updated in the particular topic filed. Then the automatic extraction method of Multi-document...
This paper aims to give an insight into the importance of green ICT course in the curriculum of Master and PhD level studies. An attempt has been made to demonstrate its necessity, implementation issues and strategic plans to execute this course. General structural plans along with details of the course content are discussed in this paper. The course aims to provide a unified view of sustainable embedded...
A novel topology of wind power generator system based on Z-source dc/dc converter is presented in this paper. With wide dc output voltage range, this topology is suitable for series dc wind farm. The operation characteristic and control method of Z-source dc/dc converter are analyzed. Simulation results of 3 series wind generators show that the wind farm interconnected with this topology is feasible.
The paper extracts acoustic emission signals between the normal condition and the crack state through the micro crack experiment of drawing parts. The local wave decomposition of acoustic emission signals was achieved to get the nine intrinsic mode functions and a tendency by the MATLAB software. The energy value of the former 8th-order IMF (Intrinsic Mode Function) were extracted as the initial characteristic...
In the communications of network, different RED parameters can be set to the WRED algorithm to suit for different levels of business, to reach the goal of differentiating the services. The package loss curve of the WRED algorithm is improved in this paper. Thus the throughput of the network enlarges and the rate of the package loss becomes lower. The improvement is testified by simulation of PTN network...
The poly(aniline)(PANI) which is a conductive polymer was blended to general-purpose polymer (polystyrene PS). Then, the PANI/PS blend films of gradient distribution composing of each component under casting conditions from polymer blend NMP solutions by using self-organization based on non-equilibrium phenomena. Electric properties of the films were examined by conducting Atomic Force Micro scope...
Under Intranet or Internet environment, it becomes more and more important how to make application systems communicate and share data seamlessly, thus eliminates the huge information isolated island, realizes the information sharing and exchange. Web services is one of the best solution for enterprise application integration (EAI). In this paper, after analyzing the architecture and the protocols...
Taking the technology of the processing and utilization of coal resource and clean coal technology as its characteristic, the discipline of mineral processing engineering of China University of Mining and Technology (CUMT) is a Chinese national key discipline, and it has formed a passel of world advanced research achievements and became an important base for the education and scientific research of...
Trade of education services developed rapidly in the past years. To begin with, this article reviews other people's research on trade of education service. Secondly, the author chooses three factors to analyze and make assumption. Then Shanghai statistics are used to verify assumptions. The verification result indicates university ranking and university location both have strong correlation with international...
