Support vector regression algorithm is applied to colleges recruiting students prediction in the paper. As colleges recruiting students prediction is a nonlinear regression problem, the input training data of colleges recruiting students are nonlinearly mapped into a high dimensional space in support vector regression model. The amount of colleges recruiting students of Sichuan province from 2000 to 2008 is used to prove the effectiveness of support vector regression method. Then,the forecasting curves of support vector regression method and BP neural network and the comparison of forecasting error for amount of colleges recruiting students between support vector regression method and BP neural network are given in this study.The comparison results of forecasting error for amount of colleges recruiting students between support vector regression method and BP neural network indicate that support vector regression method has a higher forecasting accuracy than BP neural network.

Through researching and concluding the BB-aided and Blog-aided English learning model, this paper mainly focuses on the comparisons between the two aspects like the traditional and the new modern methods. We can find that the BB-aided and Blog-aided teaching model is the new trend of the teaching technology in the digital era, which can especially enhance the efficiency of the language learning greatly. Furthermore, it would lead both teachers and students to study without the limit of time and place, which is beneficial to the choice and arrangement of the learning contents and schedule spontaneously. It is also helpful for both the teachers and students to communicate thoroughly, resulting in coaching students in accordance of their aptitude, cooperative, inquirybased, and dialogical studying, consequently causing the deep reformation of the English teaching, realising the opinion that teaching benefits teachers as well as students preferably.

This study explored the effect of screen luminance, subtitle, and viewing angle on preferred viewing distance for liquid crystal display high-definition television (LCD-HDTV). The results showed the mean preferred viewing distance was 3246 mm, about 4 times of television width. Preferred viewing distance increased as the scale of screen luminance went upward from scale 10 to scale 60, then decreased from scale 60 to scale 90. Whether there was subtitle or not did not have significant effect on viewing distance. Moreover, viewing angle was highly correlated with preferred viewing distance. The more deflected from the direct front view, the shorter the viewing distance was.

This paper mainly studies one kind of simple image encryption algorithm which can help general users to keep secret from the data information. The algorithm is modified from the DES whose processing may be divided into three steps: initial transform IP, 16 round iterations, and initial inversed transforms IP-1. Initial transformation and inverse transformation can enhance difficulty to be understood for data, and not to affect security of data. Modified encrypted algorithm, namely S-DES, carries on two round iterative encryptions to clear text. The length of block and secret key reduced. Therefore S-DES algorithm is more inexpensive than the DES encryption algorithm and remains many merits of DES.

When an enterprise information system develops into the stage of being a complex system, the relatively delayed evaluation process will result in a low success rate of information system development projects. In this article, we analyzed the characteristics of evaluation process for information system projects, studied the evaluation methodology of information systems. Based on our studies, we proposed to evaluate the information system using from qualitative to quantitative methodologies at different stages of the whole development process, guided by the theory of open complex giant system. At different stage, we should calculate expert weights according to different evaluation focus. Lastly, we illustrated the whole evaluation steps. Our proposal will improve the efficiency and accuracy of the evaluation results, which is very important to guide the information system development.

The exiting local binary pattern (LBP) operators have two disadvantages: (1) They produce rather long histograms, which slow down the recognition speed especially on large-scale face database, (2) Under some circumstances, they miss the local structure as they don't consider the effect of the central pixel. Aiming at these problems, we propose a novel feature extraction approach based on equalized uniform local binary pattern (EULBP) for face recognition. EULBP operator has two advantages: (1) It reduces significantly the histograms' dimension by doubling one-dimension pattern, (2) It considers the effect of the central pixel, thus improving the discrimination ability. The proposed feature extraction approach has been evaluated and compared with the conventional LBP and ULBP on two databases, FERET and Yale. Furthermore, in order to test the robustness of the proposed method under the condition that the resolution of the face image is low, we have also carried out experiments on the two databases by reducing the image resolution. The experimental results show that the proposed method gives the highest recognition accuracy in both normal and low-resolution conditions.
