To efficiently utilize their infrastructure and thus increase their revenue, cloud providers need mechanisms to provide resource allocation and performance isolation for different tenants in the shared platform. In particular, network bandwidth sharing is a critical yet still an open problem to most cloud providers. In this paper, we study the problem of virtual machine (VM) allocation under the consideration...
Fault location estimation, which can actually be addressed as a classification or categorization problem, is a vital feature in protective relaying scheme for power transmission lines. In this paper, a novel three-phase fault location approach based on a Multiple Classifier System (MCS) not only using the information of the faulty lines but also considering others lines adjacent with the faulty line...
This paper focuses on space-time non-linear intelligent modeling for regional data, researches how to apply back-propagation neural network (BPN) into analysis of regional data. Thinking about sectional instability of spatial pattern, this paper divided space units of researching regions into different subregions by improved K-means algorithm based on spatial adjacency relationship. Then build a space-time...
According to mapping relationship of the relative internal efficiency of low pressure cylinder of condensing steam turbine and its affection, a mathematical model based on the Immune system's wavelet network was established. It can be used for calculating the relative internal efficiency of low pressure cylinder of 300 MW steam turbine. The application of the model shows that the proposed method is...
