Virtual Machine Migration (VMM) is a key technology in data centers. Due to the uncertainty of applications in resource allocation, the imbalance of resource utilization is badly poor. In this paper, an Auto-regression Moving Average model is proposed to predict the resource requirement of a certain virtual machine, while the resource utilization rate of the physical machine is analyzed. Since the existing VMM scheme basically follows one by one migration, which makes the migration be unable to achieve the global optimum and save more energy, the paper introduces migrated cost matrix, and recommends a set of migrations with the best performance from a global point of view to carry out the migration, and improves the ``three-step'' method in the traditional migrated scheme to achieve energy efficiency. Simulation experiments show that the proposed scheme in the paper can effectively reduce the energy consumption, and can improve the quality of service in a certain degree.

Trust model is proposed in grid entity transcation because of dynamics and uncertainly of campus grid. In this paper, a trust model in autonomous domain is presented. Researching on trust value calculating and updating in domain discuss the trust value calculating model in campus grid domain, This paper proposes the algorithms about trust value calculating and updating in grid entity.

Concerning the low scheduling ratio caused by complicated QoS process and precise match in learning resource scheduling of campus grid, the authors classified and defined QoS parameters. Finally simulations were performed to compare the performance of the maximum matching scheduling algorithm with that of the multiple QoS-based resource scheduling algorithm. The paper improve a mode of learning resource dispatching which fit to campus grid, also improve the algorithm of multi-level resource dispatching.

Multimedia courseware making skills is a basic skill of normal college students in the information age. The paper analysis the existing condition on courseware making skills of 3-year Normal College Students by analysizing the sample of courseware making skills in some normal college. In addition, the paper has exploration and practice on training of the skills, constructs the multi-level skill training system, creates a multi-level and multi-channel teaching model.
