In cloud computing,the system should avoid wasting resources as a result of under-utilization and avoid lengthy response times as a result of *** research has focused on the globally optimal solution in virtualized data ***,the globally optimal solution makes a lot of unnecessary migrations and cannot work in a large-scale cloud computing *** this paper,we propose a new model for distributed load balancing allocation of virtual machine in cloud data center using the TOPSIS *** show that our system can achieve better load balancing in a large-scale cloud computing environment with less VM migration.

The concept of self access learning has been widely promoted and implemented in the higher education arena around the globe(Gardner&Miller,2011).As a result,the establishment of the self-access centre can be found in nearly every *** review of this paper emphasizes on the importance of needs analysis in the development of self-access learning materials and tasks by including different stakeholders,such as students and teachers,in the process(Gardner&Miller,1999;Sheerin,1991).The purpose of this study is to find out the perceptions that a group of second language(ESL)learners and instructors have of their/students'English skills and learning needs for self-access English learning.A total of 110 ESL students majoring in different academic fields and 6 English instructors participated in the questionnaire survey of this *** them,20 students and 4 instructors were invited to attend in-depth interviews to provide further *** and interview information included respondents and interviewees'perceptions or evaluations on two major areas:English skills and learning *** results show there are both discrepancies and similarities of perceptions between students and instructors on English skills and learning *** implications for the present context are provided.

Emergency material allocation is the core of the emergency relief response activities. This paper focuses on the problem of emergency material allocation based on maximum material utility. First, affected areas' material demand urgency and emergency donations' effectiveness evaluation index systems are proposed based on the analysis of emergency material allocation system. Then an optimal model based on maximum material utility is suggested to avoid the blind donation of emergency material. Finally, the solution of the model is analyzed and a simulation case is given with results that prove the effectiveness of the model.
