Aiming at the multimedia services in the 3G and 4G CDMA mobile communication system, a soft handover model, in which an overlaid cellular architecture including one macrocell and seven microcells with video service, is given, and link equation of CDMA discrete system in frequency domain is established. Balancing the forward link and reverse link, adjusting the parameters such as the distance and direction between mobile station and base station, the relationship between the soft handover add threshold of marcocell system and the load factor of microcell system is analyzed quantitatively, and their corresponding performances are simulated in both time domain and frequecy domain. The results are shown: the variance of distance is more sensitive to the soft handover performance than the variance of direction does.

Grid is the next generation of Internet, and it has attracted the attentions of research communities recently. In practical applications, the nodes in the grid domain need to transact with other strange nodes to acquire the services provided by those nodes. Recently, trust has been recognized as an important factor for Grid security. And it is important for them to make a trust evaluation for those strange nodes before transactions, because some nodes are dishonest. Currently, the method to solve this problem is to establish an effective trust mechanism in grid domain based on reputation. However, there are still some disadvantages in existence in some cases, as the dynamicity of the grid environment, although it can be risk-averse to some extent. Like some malicious nodes contribute high trust value through numerous good interaction behaviors at first, and then change to attack. In view of those problems and disadvantages, this paper proposes a dynamic grid trust model based on recommendation credibility, called DyGridTrust (Dynamic Grid Trust Model). This model can distinguish honest and dishonest recommendation and adjust the weight of trust evaluation dynamically. In addition, this trust model is able to obtain the trust value more objectively, so as to enhance the security of the grid system. Finally, in this paper, those perspectives have been confirmed by simulations, which are developed by Matlab R2008a.

As the progress of information technology, some financial systems used for long time can no longer meet the requirement of customers in both user interface and business process, and need reengineering imminently. In order to save the human resource and financial effort, this article raises a reengineering approach by encapsulating the back-end data access code of legacy system and only refactoring the front-end user interface and business logic. In the reengineering work, this article uses MVP (Model-View-Presenter) Architecture. By extracting screen logic into Presenters, the display code in View is independent from logic code in Presenter. Also, the introduction of MVP Architecture greatly enhances the reusability and the testability of business logic code, and finally improves the efficiency of development and test work significantly.

This paper presents a method to compute liquidity risk of stock market with model of VaR. Firstly, a measure for liquidity is defined, which reflects the volatility of return caused by unite ratio of the position to be liquidated to the tradable shares. Secondly, the density function of the measure for liquidity is estimated with support vector machine, with which the liquidity VaR of stocks is calculated. Finally, some stocks of Shanghai and Shenzhen stock markets are chosen, according to their tradable shares, to compute liquidity VaR. The results show that the liquidity VaR is bigger than the traditional VaR that is calculated without considering liquidity, which means the latter does underestimate the risk.

Same layer webpage have similar presentation styles and noise blocks. The first step of data mining is to remove noise blocks from web pages. Different from traditional similarity measurement method based on DOM trees, a noise removal method based on image features is proposed in this paper. In this method, web pages are processed as images. And then, all of image features can be flexibly used as criteria to measure similarity of noise blocks. As a result, noise blocks and information blocks can be distinguished after measuring similarity, and the reduction of noise is realized. The results of experiment demonstrate that this method is accurate and reliable and it can support joint measurement of multiple image features.

Driver fatigue and decentralization of spirit at night is a major factor causing the night-time traffic accident. Eyes locations are the precondition to monitor driver's fatigue state with image processing technique. Based on Otsu threshold segmentation algorithm, with the help of horizontal projection and vertical projection in binary image, the paper locates the driver face region accurately, and establishes eyes location based on the region labeling algorithm. The paper using Laplace edge detection gets eyes contours points, and then fits these points by ellipse fitting. Experiments have proved good reliability and validity of the algorithms.
