As a new teaching mode, Flipped Classroom facilitates the reform of education model and innovative talent cultivation. In China, English Linguistics is an important course in English major. However, as to the content is abstract, it is difficult for the students to learn. The students are in a passive role to learn in class. The learning outcome is unsatisfactory. Therefore, it is urgent to change the current situation and adopt new mode.展开更多

With the advent changes of technologies pertaining to location transparency in storage of data, there arises different access control scenarios. Cloud storage, the predominant storage that is being in use currently, also paves way to various access control problems. Though there are various access control mechanisms such as RBAC, ABAC, they are designed on the user’s perspective such as the role held by the user or other attributes assigned to the user. A new access control mechanism called object relationship based access control (RoBAC) has been developed based on the relations held among the users. The policy decision of access control is based on the relationship among the classes followed in the Java programming. Results have shown that this model best suits various scenarios in the cloud environment, and it also shows that the time for making decision either to allow or to deny is reduced compared to the existing system.展开更多
