Grid resource management plays an important role while enabling the sharing and coordinating of resources in grid computing environments. Resource reservation is an important part of the grid resource management. An advance reservation is a scheduling object which reserves a group of resources for a particular timeframe for access only by a specified entity or group of entities. Combining resource...
A major challenge facing grid applications is the appropriate handling of failures. Data replication is a key technique of data grid, from which, we can get better access performance. It is a fault-tolerant approach, but at the same time bringing some hidden trouble for security, so security and fault-tolerance should be colligated to research. Combining data replication with security, we propose...
Mobile learning means learners can access learning resources at anywhere and anytime with mobile devices; Because these devices operate in different ways and have different capabilities, so some learning resources may not be in a format that different mobile devices accept. In order to provide learners with appropriate courses, a project on mobile learning platform supporting three-layered structure...
Full scope simulator was adopted to teach simulation practice of power plant operation in North China Electric Power University. It solves the contradiction between the safety of power plant operation and teaching practice. College students can startup, shut down the devices, adjust running parameters and treat malfunction on simulator. Compared with practice in real power plant, the teaching effect...
Entrepreneurial development has been viewed as a driving force for the successful transition from planned to market economies. Based on social cognition and self-efficacy theory, this study proposes an entrepreneurial self-efficacy based model of entrepreneurial intention. The model presents the complex interaction among entrepreneurs' individual characteristics, transition environment, entrepreneurial...
Based on the theories of arc and gas discharge, a novel hybrid arc model in vacuum circuit breaker is proposed, considering the factors influencing on the arc formation from both microcosmic and macroscopic views. The evolution from initial discharge channel forming with breakdown to steady arc state is simulated. The results show that the radii of discharge channels are enlarging and the shapes of...
In order to evaluate impact of port development on regional economy, this paper adopted fuzzy comprehensive evaluation, a combination of qualitative and quantitative methods, and established an evaluation index system which includes four main criteria: total economic output, industrial structure, relevant industries and environment. The findings reveal both positive and negative impacts of port development...
The lead-time for the retailer's inventory system may be changed with different suppliers in chinapsilas low technology industries. A multi-agent simulation system is proposed to simulate this category of dynamic supply chain. In the simulation system, the retailer's stock was controlled by (S, s) policy, and then four categories of supply chain scenarios were suggested. Four propositions were achieved...
We consider user cooperation in a relay network that comprises a large collection of transmitters sending wireless data to a common receiver. A new framework exploiting the network coding technology, referred to as adaptive network coded cooperation (ANCC), is proposed to combat the lossy nature of wireless links and to adapt to the changing network topology. The central idea is to match network-on-graph,...
