Abstract: An electronic tongue which composed of selective electrodes is applied to mineral water recognition (optimization of sensor array). The task of the system is to distinguish among five brands of mineral water. For this purpose, various pattern recognition (PARC) procedures are employed: principle components analysis (PCA), independent component analysis, linked-like adaptive genetic algorithm (LAGA), et al. LAGA networks are proved to exhibit the best performance both in array optimization and mineral water recognition. Their further advantages, such as fast training and robustness, make them the suggested pattern classifiers for sensor array data.

Abstract: Multi-channel Virtual reality simulation technology is a kind of simulation technology, which support the grand scene and high degree of immersion, has better visualization effect. In this paper, a moving target monitoring collaboratory simulation technology based on multi-channel is studied. Firstly, study the mathematical modeling foundation of Multi-Channel technology systematically, based on the mobile target spatial model and co-simulation technology, select the appropriate applications of multi-channel technology, building laboratory simulation platform and achieved a space-based six-degree of freedom simulation of multi-channel moving target monitoring simulation. The experiment has proved that in multi-channel target monitoring co-simulation technology used in this paper has strong practicality, combine with a moving target-space model and co-simulation technology, the advantages of objective observation to solve the requirements like large-scale, realism, immersion requirements, etc.

Abstract: Public verifiability in signcryption achieves public verification of signature by a trustable third party; it ensures the reliability and secure parity of signcryption scheme. In the paper, we analyzed the public verification algorithm in signcryption and presented signcryption scheme without verifiability based on discrete logarithm problem as a comparison. Signcryption without verifiability satisfies the basic requirements of authenticated encryption; it can achieve secret message transmission and identity authentication in a single protocol. But the signcryption sender can cheat in the protocol with forged information for lack of supervision by public verification. Then we presented an improved signcryption scheme with public verifiability, in the scheme signcryption message is generated with private key of message sender and other public parameters, any trustable third party can verify the signcryption without disclosing private key or secret parameters. Besides, the attack on the signcryption and secret parameters via public verification data is computationally infeasible. The scheme reinforces the security and reliability of signcryption and effectively improves its efficiency for engineering application.

Abstract: As community informationization is the extension of e-government, to perform informationization construction in city community construction could enforce community construction and management, perfecting community functions and improve community service quality. However, as there are differences in the environment, conditions and aims of community management both at home and abroad and among domestic cities, community construction can't adopt one same model or to copy entirely from others. Considering this, research on the development laws and model of community informationization is the necessary premise of successfully making community informationization construction. Through analysis on the present state of community informationization both at home and abroad and in major domestic cities, this paper makes a summary of community informationization construction and explores relevant development models, providing helpful references for government to make community informationization construction.

Abstract: Community informationization has become one of the most active and attracting fields in city informationization. It attracts large amounts of capital, technology and talents. The governments, companies and community residents pay much attention to it. To construct community informationization is not only one issue of city informationization, but also is the basis and an important part of city informationization construction. The paper has made a conclusion and research on the problems existing in the construction of community informationization in connection with the process of present city informationization construction. Furthermore, relevant strategies and advice are presented according to the existing problems, providing some help to the community informationization construction in the city informationization construction.

Abstract: In this paper we propose an image corner detector based on the direct curvature scale space (DCSS) technique, referred to as the curvature product DCSS (CP-DCSS) corner detector. After the contours of interested objects are extracted from a real-world image, their curvature functions are respectively convolved with the Gaussian function as its standard deviation gradually increases. By measuring the product of the curvature values computed at several given scales, true corners on the contours can be easily detected since false or insignificant corners have been effectively suppressed. A point is declared as a corner when the absolute value of the curvature product exceeds a given threshold and is a local maximum at the mentioned point. CP-DCSS combines the advantages of two recently proposed corner detectors, namely, the DCSS corner detector and the multi-scale curvature product (MSCP) corner detector. Compared to DCSS, CP-DCSS omits a parsing process of the DCSS map, and hence it has a simpler structure. Compared to MSCP, CP-DCSS works equally well, however, at less computational cost.

Abstract: As an important role of supply chain, management impact deeply on the efficiency of the supply chain. This article first introduced the relational theory of rough set, then described the application on the customer risk management based on the analysis of a large number of historical transactions, gave the realization of computer program, and detailed the practical application. It has greatly proved the effective of the theory.

Abstract: Paper introduces a kind of design method of electronic component searching system. System acts ASP language as development way of dynamic web based on B/S mode. System can realize electronic component browser, searching, PDF file material uploading and download, etc. In this paper, we mainly introduce design of system parts of function sub-system and each web pages source file in detail. Though system practical running on web server and user feedback information, we get uniform good reputation. System can help student study electronic component function and use way, etc. In addition, some of system function sub-system can be replant into other web system. Through experiment, system has widely replanting and application value.

Abstract: The designed and experimental process of the teaching and playback(T&P) control system for R-CUBE is narrated. The control system was connected by CAN bus and has a distributed structure. The design thought and basic work principles of the control system about R-CUBE that regards the C8051F040 as the core are introduced, the basic circuit diagram of the hardware system and the software design projects are also provided. The teaching and playback progress was executed as several modes, with the control of three operator model, the teaching and playback of motion for R-CUBE could be realized.
