摘要：
This paper proposes a new feature of fingerprint, called corner-cue. It is based on the curvature of fingerprint ridges. To extract the corner-cue, we first compute the curvature of fingerprint ridges and find the local maximum curvature points. Without regard to the high curvature points near minutiae, corner-cues are obtained. Corner-cues are further utilized in the matching stage to enhance the system's performance. Since high curvature points are important features of a fingerprint, the proposed method can obtain better results than conventional solely minutiae-based methods. Experimental results illustrate its effectiveness.
摘要：
emerged as a promising technology for nextgeneration wireless network. In WMNs, many important applications, such as audio/video conferencing and distance education, require the support of multicast communication with quality-ofservice (QoS) guarantee. In this paper, we investigate the issues of QoS multicast routing in wireless mesh networks. The paper studies TDMAbased timeslot allocation, and presents an effective heuristic algorithm for calculating end-to-end bandwidth on a path. We also propose a novel source-based multicasting routing algorithm to build a multicast tree among all the multicast members. Simulation results show that compared with MAODV, our proposed QoS routing algorithm can significantly improve the performance of QoS multicast routing in WMNs in terms of success ratio and network cost.

摘要：
In order to enhance terrain data network service performance, P2P technology is gradually used in large scale terrain data roaming system. It is vital to research on how to construct terrain data peer-to-peer (P2P) storage model according to its features. In this paper, we present a terrain data P2P storage model according to the pyramid model. In our terrain data P2P storage model, terrain data is organized as multi-resolution pyramid model based on multiple of 2, and data blocks among different levels are denoted in quad tree structure. Furthermore, system structure based on the P2P storage model is logically divided as three layers: terrain data server layer, terrain data service layer and terrain data download layer. Terrain data server layer is composed of data servers in traditional C/S model, and its main function is not directly to provide download service to terrain data users, but to manage, distribute and update terrain data in the system. Terrain data service layer is composed of part of clients in traditional C/S model, and its main function is to provide data search service and maintain terrain data download layer. Terrain data download layer is composed of another part of clients in traditional C/S model, and its main function is to store terrain data and provide data download service each other. From the primary test of this model, we find that the terrain data can be downloaded from more than a node so that the download speed is greatly accelerated using the terrain data P2P storage model, which can realize the massive data transmission at the lower cost compared with the single broadcast.

摘要：
The selection of the bridge type generally depends on the designer's experiences at the present time. It exist some subjectivity and one-sidedness unavoidably. On the basis of the characteristics of complexity and the uncertainty of optimal selection of bridge type scheme, grey relational analysis model in bridge type multi-scheme selection application has been put forward in this paper. The index system of influencing bridge type selection is determined. Application model and procedures of the grey relational analysis method are introduced. According to the degree how close it is with the ideal dot, the optimal scheme is easy to be selected out. Through the optimization analysis of Soueryu Bridge type schemes, it is proved that the optimal scheme of bridge type based on grey relational analysis has the strong recognition judgment ability. It is convenient, quantitative, and strict. It provided a new method and a possible new way for optimal selection of bridge type scheme.

摘要：
On the basis of communication process a Stochastic Petri Net (SPN) model is constructed to analyze the performance of Wireless Sensor Networks (WSNs). The effects of arrival rate, data packet number, sink node's buffer size on average time delay, throughput and the utilization of the sink node buffer are also analyzed by solving the linear equations from corresponding isomorphic Markov Chains of the SPN model under different parameters. The proposed approach has great benefit to the design and performance evaluation of WSNs.

摘要：
As a new evolutionary algorithm, particle swarm optimization (PSO) algorithm has been gained much attention and wide applications in different fields during the past decade. However, for nonlinear, nondifferentiable and multi-modal problems, the PSO algorithm often suffers the problem of being trapped in local optima so as to be premature convergence. To enhance the performance of standard PSO, the particle velocity variation strategy (PVVS) is introduced in PSO, and variation PSO (VPSO) algorithm is proposed. Compared with SPSO, The results of the numerical experiment show that the proposed method can not only significantly speed up the convergence, but also effectively search the global optimal point.

摘要：
The traditional education teaching model is no longer adapted to the current situation with technology advancements, modem teaching methods development and quality education policy implementation. Classroom teaching efficiency should be improved, traditional teaching information transfer mode also should be reformed in order to make up for deficiency of the traditional teaching model. It is a great subject of higher education reform using multimedia technology to implement information teaching, which can promote quality education. Both teaching and learning is the principle, mobilizing the student enthusiasm and subjective initiative cognition is the target and student subject position is the kernel in the teaching implementation process using multimedia, Then the pertinence multimedia teaching has been carried out, the interaction in teaching and learning and the relationship between teachers and students has been studied, and the benefits of multimedia teaching, such as improving student capacity of obtaining information, cultivating the innovation capacity, improving the teaching efficiency and quality has been analyzed. It can not only cultivate students' innovation, but also optimize the teaching effectiveness.

摘要：
As we all known that a socioeconomic system is a complicated system. A system designed here may be expected to get good control effects. Firstly, grey state modeling and modal decomposition is proposed. Secondly, an approach to modal control, which is to control the socioeconomic system's behavior in advance is designed. The applicable field of modal control systems is rather far and wide especially for varieties of multivariable complicated systems.
摘要：
We propose a scalable routing architecture for next generation gatekeeper. The design principle is that gatekeeper call routing may be separated from its call process. Next generation multimedia networks, with large capability and multi-domains, consist of Connecting Domain for call routing and Service Domain for call process. Next generation gatekeeper adopts Telephony Routing over IP to realize dynamic routing. We consider this routing as a special type of service and investigate the method of routing creation and routing provisioning. Validation in a testing platform shows that the proposed routing architecture can provide admirable routing performance.

摘要：
Regional gross national product (GDP) is an important indicator of national economic accounting. Regional GDP is an important part of the country's GDP, and it is of great significance for formulating scientifically the strategy and the policy of regional development that to effectively forecast regional GDP. A method based on genetic algorithm optimizing grey modeling process is introduced in this paper. This method makes full use of the advantages of the grey forecast model and characteristics of genetic algorithm to find global optimization. So the forecast model is more accurate. According to data from a province, the GM (1, 1) model for forecasting regional GDP was given based on the grey system theories and genetic algorithm. The result indicates that the model can be used as regional GDP an effective tool for forecasting.
