On behalf of The International Conference on Computer Science and Service System (CSSS 2011), it is my great pleasure to welcome you to the conference. This annual international event has attracted a great number of academies, scientists, engineers, postgraduates and other professionals from a large range of countries. CSSS 2011 will provide a forum to discuss a large array of computer science and...
This paper adopted Guizhou 2005 TM/ETM satellite image data and analyzed its rural Ecological landscape pattern(RELP) by using GIS software. It was shown that Guizhou rural landscape distribution difference was big, landscape fragmentation was high, agricultural landscape integrity was poor. Besides the fractal dimension of settlement landscape is relatively lower, the others were quite high. Rural...
Colorimetric characterization is the basic work of color reproduction. To find an optimized method to evaluate different types of displays is of great importance. The object of this study is to compare several universal algorithms which can be used for different types of displays. Different color space and whether gamma correction is applied are considered. The results illustrate both methods generated...
The data mining technology is more and more widely used in the telecom industry. But telecom data set always includes instances with missing values. Besides, many data mining models are sensitive for the missing value and distortion. Estimating missing values becomes an inherent problem. To address the problem, A prediction method is proposed for the missing value based on the BP neural network and...
A data processing software package is developed for passive seismic monitoring of hydraulic fracturing. The original seismic data is acquired by a surface array which has many stations work independently. The package converts original data files into SEG-Y format files, and files of all stations are synchronized and combined according to GPS time. Many methods are utilized to perform signal analyzing...
This paper proposes a GMPLS survivability choice scheme based differentiated services. This algorithm which is based on three normal GMPLS survivability scheme models (namely Global Protection, Reverse Backup and Local Repair) chooses evaluation function to decide in advance most suitable restoration model for working path of each kind of traffic, then only employs it to calculate the backup path...
Storage device performance prediction is a critical element of self-managed storage systems and application planning tasks, such as data assignment and configuration. We proposed a new hybrid method (RT-RBF), which combines regression tree (RT) and radial-based functions network(RBF), to model storage device performance. In our proposed algorithm, the RT is firstly used to split the large space of...
The newly proposed Two-human CardiffGA has been shown an improvement on the CardiffGA in some respects because it offers a new sort of framework for multiple population GAs which is much closer to modeling the real world. Current tests have shown the TH-CGA has a lower success rate than the S-CGA but requires fewer genetic operations and to be overall computationally faster than S-CGA when it does...
A global convergence Infeasible Interior point homotopy method for solving horizontal linear complementarity problem has been introduced in this paper. We give the homotopy equation and prove in details the existence of the smooth path from almost any positive orthant initial point to a solution of HLCP. We give several preliminary numerical results. Numerical results are presented to show the effectiveness...
Aim at the inefficient problem of existing QoS-based Web service selection approach, the paper defines the marks of new Web service to distinguish between current and new. It is an improvement of existing QoS-based Web service selection approach based on this paper. The range of Web Services selection has been limited, namely the best quality of Web Services are selected from the new Web Services...
In order to solve the problem of state-extend in network multicast, aggregated multicast algorithm was proposed. Based on the existing routing algorithms, this kind of swarm intelligence algorithm (ant colony algorithm) can construct matching between aggregated trees and communication groups in the concurrent multicast groups and consequently improves the communication quality of network. Group-tree...
Fuzzy preference relations are widely used in decision-making problems for representing decision maker's opinions on the alternatives. A new approach has been presented based on generalized consistency to rank all the alternatives in the decision making with fuzzy preference relation. Based on the concepts of multiplicative consistency and additive consistency, we propose the generalized consistency...
As optical networking becomes a promising choice to meet the ever-increasing demands on bandwidth, constructing multicast wavelength division multiplexing (WDM) switching networks with cheap components and low complexity is a key issue. On the basis of four-stage Clos network, we propose an optimal model of wide-sense nonblocking multicast (WSNBM) WDM optical switching networks. Our analysis shows...
Under the synchronous condition, based on the character of the receiving signal constructs and the theory of finite operator, a new decorrelating multi-user detection method is obtained. With this new method, the computation of the reverse matrix of the correlating matrix can be avoided, so it is very valid to decrease the computing complexity. Besides, the performance of this new MUD method can be...
