In the CDMA cellular mobile communication system, the order of neighbor cell list (NCL) determines whether the mobile station can make a success handoff to the best neighbor in time. Therefore, the success rate of handoff depends on the suitability of the NCL's management, which directly affects network performance. Traditional NCL algorithm used the method of manual observation and was adjusted by the long-term performance data. This paper presents a new algorithm of optimizing NCL, which based on the pilot signal interference ratio (Ec / Io) from daily test data and realizes it in a real CDMA network. The simulation results show that this algorithm reduces manual labor and also considerably has reference value for daily optimization.

High-dimensional geometry is a vehicle to achieve biomimetic pattern recognition, which is a new model for recognition science and always to construct convex cell bodies for covering samples points in the space. By this way, in this paper, some k- dimension simplex were constructed for the purpose of covering the sample points of each class in the feature space, and then computed each the shortest distance between a sample waiting for recognizing and each simplex for face recognition. The method was applied for some famous face database, and the experimental results indicated that it was better than that of SVM,and indicated its effectiveness and feasibility.

Communications system with more antennas carried in vehicle, plane and ship is regarded as antenna and scatter body structure. Wire antenna and scatter body structure with faceted triangle and quadrangle surfaces are taken into consideration. An partition approach consisting of three steps is presented. The first step is to partition all surfaces of the scatter body by recursively bisecting each triangle and quadrangle to get the required sizes of all elements, neglecting the presence of antennas. The second step is to partition the elements connected with the wire antenna into smaller areas. The third step is to partition the narrow elements to improve their shape quality. Engineering applications show that this algorithm is stable, reliable, fast.

Despite the large-scale adoption of enterprise resource planning (ERP),attaining the expected benefits is still a challenging task.Organizational culture,a representative of holistic organizational context,is always neglected by prior studies when focusing on ERP assimilation.Through analyzing relative literatures, this paper drew upon five dimensions (interpersonal harmony, outcome orientation,innovation,control,and efficiency) of organizational culture in Chinese context,to explore its impact on ERP effective assimilation through the mediating roles of user participation.And then,a comprehensive research model was built, and then was tested.(Abstract)

With the development of nonlinear science, the existence of long memory in the financial market volatility has been found, which is inconsistent with the weak form of Efficient Market Hypothesis. With the brief introduction of Heterogeneous Market Hypothesis and Fractal Market Hypothesis, the long memory behavior of Shanghai Stock Index's returns volatility is tested, based on H/S analysis and GPH method. By using the realized volatility to measure the true volatility and combining with the analysis of ARFIMA-RV and HAR-RV model, Shanghai Stock Index's RV series' long memory behavior is confirmed, and HAR-RV model behaves better in the prediction of volatility.

High resolution radar system usually has a massive amount of raw data, so we have to carry out data fusion as quickly as possible. In this paper, we propose a fast clustering algorithm based on single dimensional distance calculation. The proposed algorithm divides raw data into subsets by single dimensional distance, and then merges subsets according to single dimensional distance and set-density. At last we apply the proposed algorithm to carry out data fusion for airport scene surveillance radar system. Experimental result shows the proposed algorithm has high execution efficiency and is not sensitive to noise data; it is useful for high resolution radar data fusion.

Medical image classification is an important part in domain-specific application image mining because there are several technical aspects which make this problem challenging. In this paper, we firstly quantify the domain knowledge about medical image (especially the symmetry), and then incorporate this quantified measurement into classification. We propose a multistrategical image classification method which utilizes various features by integrating two base classifiers. In our method, a base classifier is trained using the examples misclassified by another base classifier. Therefore, both base classifiers can be collaboratively trained. This complementary method gets a more efficient classification.
