According to the confluence theory of hydrology, the paper discuss the method of calculating the water-logging of the surface in the region. Combined using the spatial analysis in GIS with calculating the "Isochrones" in the confluence of regional water-logging, to describe the distribution of the confluence in space and the strength of the confluence in time. At the end of the procession, it gives the space and time maps of spatial and temporal distribution of the water-logging's confluence. The research evidence that the confluence's strength in time is closed to the elevation of the research region, and the confluence's distribution in space is closed to the distribution of the river.

To benefit of both regular topology and partially customized structure, we adopt application specified link removal strategy to minimize NoC (Network on Chip) area consumption with partial regularity twist and guaranteed performance. Our link removal for single application mainly includes iterative link removal selection algorithm based on low link utilization for topology optimization and turn model based deadlock free routing algorithm for irregular 2D Mesh with reduced links. In addition, we also consider multiapplication from realistic requirement and try to define various execution modes. The seamless combination of multiapplications and link removal method is achieved via corresponding interoperation of removed link set. Taking typical media applications VOPD and MWD for example, the simulation results verify proposed multi-application specified NoC link removal strategy valid for area cost optimization and acceptable performance degradation.

As a kind of hybrid financial instrument, the pricing of convertible bond (CB) has constituted a great challenge. This paper developed a novel method integrating support vector machine (SVM) with copula function. Different from existing single-factor or bifactor pricing models based on corporate value and the underlying stock price respectively, this model can effectively deal with many constrains on the CB pricing, such as nonlinearity, departure from normality, multivariate joint distribution, variable dependence structure, and so on. In particularly, the new model exhibited great flexibility in that copula function can portray dependence structure between the underlying stock price and interest rate, and that SVM can further tackle nonlinear relationship among variables. Empirical analysis showed that the proposed model enhanced generation ability of out-of-sample, with mark increase in CB pricing accuracy compared with the single SVM, and that the CB value sensitivity to the underlying stock and the dependence structure is also measured handily and effectively through the model.

In order to acquire the peak performance of one storage system quickly and accurately, an automatic parameter optimization method is used in performance test. By introducing artificial intelligence into storage test, the algorithms such as particle swarm optimization help to optimize parameters automatically on performance test. Experimental results show that this method can significantly improve efficiency and accuracy of performance test, so saving cost. The method based on intelligent optimization algorithms can acquire the optimal performance value of storage systems more quickly, especially in the case of there are too many parameters in performance test.

A cellular automaton model with extended neighborhood is presented to simulate an infectious disease outbreak. The model facilitates the study of the dynamics of epidemics of different infectious diseases. The effects of different infectivity parameters, infectious cycles, and medical intervention strategies have been studied. The proposed model can serve as a quantitative basis for future medical intervention strategies.

Location of retail stores in logistic system involves many factors, some of which are quantitative, others of which are qualitative. The weight of each retail place is calculated by using AHP on the basis of analyzing the factors, then a location model is proposed by combining AHP and 0-1 programming, for AHP can not solve the problem with constraint. Finally the model of retail place location in logistic system is proved to be effective by examples.

This study, based on a survey of 1000 manufacturing firms in central south, south and central China regions, examines the relationship among supply chain performance, competitive advantage and firm performance. By exploratory and confirmatory factor analyses, the scale of manufacturing firm's supply chain performance is obtained. The results show that supply chain performance can be conceptualized as a four dimensional construct: supplier performance, customer responsiveness, supply chain flexibility and supply chain cost. Furthermore, after testing research hypotheses by LISREL, we find that these four constructs all have significant effects on competitive advantage, and that each of them except supplier performance has significant effects on firm performance. The implications for our findings are also presented for the improvement of manufacturing firm's supply chain performance.

With the development of network, the online information has greatly enriched. It is increasingly difficult to obtain the desired information. The search engine can solve some problems, but far from satisfying people's needs. With the development of Web 2.0, RSS technology can solve some problems, greatly reducing spam, but as more and more channels appear, the user once again gets into the "information overload" situation. Therefore, in this paper, we use machine learning techniques and effective text classification techniques to solve the problem of information overload in a certain extent.

Matrix equation problem is one of the topics of active research in the context of computational mathematics. The Hermitian positive definite solutions of a matrix equation play an important role in real applications. In this paper, we present the sufficient conditions for the existence of the positive definite solution to the nonlinear matrix equation X -- A* 2m square root X-1 A = I and propose a natural and stable iteration algorithm for obtaining a positive definite solution of this matrix equation. Finally, two numerical examples for the convergence behavior of the proposed algorithm are conducted to demonstrate the effectiveness.
