To reduce datacenter energy consumption and cost, current practice has considered demand-proportional resource provisioning schemes, where servers are turned on/off according to the load of requests. Most existing work considers instantaneous (Internet) requests only, which are explicitly or implicitly assumed to be delay-sensitive. On the other hand, in datacenters, there exist a vast amount of delay-tolerant...
When shipping corporations plan design their voyages and the method of port berthing, port jam is a factor of much concern to them.Through analysis of the features of the spatially inhomongeneous shipping flow phase, this article uses the master probability equation model and Kerner’s three-phase flow theory to explain the cause of the free flow phase’s conversion to the synchronized flow phase.Putting...
This paper proposed an improved video-based texture synthesis approach for simulating realistic natural phenomena. The algorithm measures similarity of every two frames to determine a preliminary playing sequence and then divide the preliminary playing sequence into several subsequences with different frame-to-frame delay so as to remove visual discontinuities. For removing the abrupt change from...
Collaborative virtual environment (CVE) is a multi-user virtual environment that supports distributed collaboration. The two main issues that CVE is facing are how to improve system scalability and quality of service. Combining Active routing and content-based publish/subscribe and taking bi-directional shared multicast tree as the communication structure of Interest Management, Active interest management...
