Link prediction is a basic problem in the research of social networks. At present, most link prediction algorithms are based on the features extracted from network structure, few research concerns the effect of natural attributes of nodes for creating a link. In this paper we develop a novel way to predict links based on Random Walk algorithm using the information from both the network topology and...
We investigate the impact of the node-selfishness on the network connectivity and the path delay of information dissemination in large scale Ad-hoc networks based on the percolation theory. A network framework with links obeying stationary process is conceived by combining the effects of both node-selfishness and link qualities. The existence of the node cooperation probability boundary is proved...
In multimodal optimization, maintaining population diversity is one of the most critical issues in genetic algorithm design. A number of niching techniques have been developed and successfully applied to cope with this problem. For multi-population based parallel genetic algorithms, nevertheless, these approaches are obviously inapplicable, since it is very difficult to obtain global information about...
To increase the intelligently reconfigurable capability of manufacturing cell control system, the basic function block model adapting to intelligently reconfiguring is proposed, and intelligently reconfigurable manufacturing control system utilizing the model as function cell is constructed. Under the research background of a manufacturing cell, Unified Modeling Language (UML) class diagram method...
Death of part of the nodes in wireless sensor network is a key problem to affect lifetime of the whole network. To avoid early death of such nodes, we put forth a children parent scheme implemented with Leach protocol. The children parent scheme allows supplement of nodes when some node runs out of energy due to causes such as hot spot or unbalanced network topology. Experiment results show the scheme...
Okadaic acid (OA), a key diarrheic shellfish poisoning (DSP) toxin will possibly arouses DSP symptoms by consuming the contaminated shellfish. The DSP toxins are stable at high temperatures, and long-term DSP toxicity is carcinogenic. Therefore a fast and reliable analytical method for the detection of OA and analogues in shellfish is worth developing. In this paper, a direct competitive ELISA (dcELISA)...
Value-added tax revenue occupies an important position in China. The efficiency study of value-added tax has important practical significance in the critical point of Chinese value-added tax transformation. Using BCC model we estimate Chinese value-added tax comprehensive efficiency, pure technical efficiency and scale efficiency from 1995 to 2008 from a macro perspective. The study shows that value-added...
By investigation and study on present rural residence status in a typical Hot Summer and Cold Winter zone Zhejiang Province, this paper points out issues like high energy consumption, high cost, low life-span, low quality, etc. proposes the design strategy for green rural housing in New Countryside Construction. The author makes analysis from different aspects including the continuity of ecological...
Maintenance policy should be selected reasonably to reduce operation expenditure and increase production benefit, and in this flow all the related factors need considered. Usually, this work depends on RCM logic decision. This paper adopted the set pair analysis method to establish multi-attribute decision-making model of maintenance policy, so as to make the choice of maintenance policy effective...
The information industry can stimulate economic growth and create enormous social wealth. This paper analysis the integral part of China's information industry. At the same time, this paper researches its development status. Combining the characteristics of information industry, we find out the inadequacies of the information industrial policy. At last, this paper provides kinds of policy to promote...
This article described the concepts of workflow, scientific workflow and three open-source scientific workflow engine, illustrated on how to establish and modify scientific workflow model. And analyzed the implementation of a scientific workflow process.
Building on previous researches, this study empirically tested the relationship between undergraduates' academic stress and their perceived psychological distress, and the moderating effects of psychological capital. Using a sample of 118 undergraduates from a university located in Northern China. The hierarchical regression analysis with SPSS 16.0 was employed to test the hypotheses. The results...
