Abstract: With the increase of softwares scale and complexity, peoples awareness of software quality guarantee gradually become stronger. The software engineering is faced with the practical problems of how to conduct softwares test, optimize the test, select the test act and increase the test effect. With multidimensional indexes of the test coverage, this study puts out an optimizing act which uses integration test coverage, test coverage satisfaction rate and test efficiency as the utility properties. The multiple attributive decision-making act of selection algorithm is used to measure the optimal act, reducing the dependency of subjective experience in testing, providing a rational and effective instruction for test.

Abstract: By designing high reliable modules with special functions, the paper realizes the identification to security compiler expansion grammar, shows compiling information of the control flow testing level and supports grammar security subset; it also achieves the grammar highlights of a variety of highly reliable security algorithm by using the dynamic profile approach, which provides more safety guarantee to the development of embedded systems from its beginning.

Abstract: Group signatures allow members of a group to sign messages anonymously on behalf of the group. Only a designated group manager is able to identify the group member who issued a given signature. In this paper we propose a new group signature scheme based on RSA, which is a blind signature algorithm. A multibank E-cash system has been presented based on the proposed scheme. A general design scheme including withdrawal, payment and deposit process is discussed particularly.

Abstract: With the development of China’s e-government, online digital government micro-blog (GMB) have become one of the emerging areas of the service-oriented administrative build-up. In this paper, we conducted a quantitative and qualitative probe on effect issue and are devoted into the applicability analyses. Based on Nielsen’s usability principle, a theoretical model of applicability is initially constructed. From the perspective of citizen’s needs, the paper evaluates the weight of indicators that represent applicability by the approach of Analytic Hierarchy Process(AHP) . Findings from the study suggested that China’s GMB practice is still at its early developmental stage under standard of quantitative scope and needs upheaval in system construction.

Abstract: By collecting the major group buy websites data, this paper using factor analysis and cluster analysis in data mining methods to analysis it, classify the group buy website, find and analysis the group buy website operating key strategy.

Abstract: With social network analysis to deeply resolve the social network of users and the network of the thematic network, this thesis is aimed to explore the natures of the node and the Internet as well, find out the potential community, and deepen the analysis of the community, in order to obtain information of structural holes in community. Besides, the feasibility and utility of methods exerted in the thesis were illustrated by experiments. The study of the thesis supplies the help to the online shopping platform with figures theoretically and technologically. On the other hand, through investigating people’s interest in goods, the thesis is also based on to study the user’s investment and the optimization of the online shopping platform.

Abstract: The paper firstly gives an analysis of the role of electronic commerce of agricultural products on agricultural development, and existing problems, and it raises the innovation of electronic commerce modes including the selection of P2B2C mode and P2G2B mode, and gives detailed suggestions such as setting up the third party e-commerce trade pattern, speeding up the construction of farmer agents, the construction of logistics system, and construction of agricultural standardization system.

Abstract: Aimed at the modeling of governments public strategic decision-making, this article proposes a decision-making optimization model for the traceable food system. A welfare function of industry producers, whose parameters would be estimated by actual data gained from market survey and statistics analysis, is established based on the decision-making model in concern of mean value. Finally, the decision-making procedure is converted into a convex optimization problem, which is solved by the inner point method. Investigation shows that the optimal ratio of government subsidy to pay for the technology expenses of every unit is 0.82%, which would lead to an 11.72% increase of expected profit for the enterprise whose decision is led by the traceable system and having large productive scale and high sales prices. Thus the optimal condition can be obtained in the implementation of the traceable system. At the same time, any enterprise with a suitable vertical integration rate and owning quality verification systems will find that it is easier to establish the traceable system.

Abstract: Drawing on the status of brand community research and the needs of enterprise practice, this paper explored the relationship between the motivation and the behavior of consumer engagement in online brand community from the consumer's perspective and concluded the driving forces of consumer engagement are social intercourse, information, entertainment, and benefit and achievement motivation. With factor analysis, motivation of consumers’ engagement in online brand community was studied to resolve the connotation underlying the brand community, which provides further reference for the company to select consumer-oriented strategy proposals on online brand community management.

Abstract: Traditionally most of the student attendance monitoring in colleges has manual based solutions, which are of low efficiency and poor accuracy. Using the contactless IC card technology, student attendance management system based on campus smart card platform has been realized, which will provide effective and accurate answer for monitoring absences with reduced workload. This system has achieved good practical performance, improved management quality and efficiency, and also accelerated the application of information technology.
