From the perspective of the dynamic system, four-dimensional theory of educational management services has been established, which consists of school education, social environment,...
Analytical solutions are considered as increasingly important for modern enterprises. Currently, systematical adoption of analytical solutions is limited to only a small set of large enterprises, as the deployment cost is high due to high performance hardware requirement and expensive analytics software.

It is becoming common practice to migrate signal-based video workflows to IT-based Video workflows. Video workflows have some inherent features, including: 1) necessary human involvements in video workflows introduce security and authorization concerns; 2) the frequent change of video workflow contexts requires a flexible approach to acquiring performance data; 3) the content-centric nature of video...
According to the widely used IEEE 802.15.4, one of the most effective ways to reduce the power consumption of sensor nodes is to enable the optional sleep mode by radio shutdown. In this paper, we propose an extended Markov-based analytical model for IEEE 802.15.4 slotted carrier sense multiple access/collision avoidance (CSMA/CA) algorithm considering the newly enabled sleep mode. For taking account...
