To avoid unpredictable losses because of network failure, the reliability of the network needs to be evaluated in some application scenarios. This paper start the network failure prediction research upon 14 months' network alarm logs we collected. The logs are of one Metropolitan area network. The research method is shown as below: firstly, construct features to represent network characteristics by...
Understanding the intelligence of human behaviors by mining petabytes of network data represents the tendency in social behaviors research and shows great significance on Internet application designing and service expansion. Meanwhile, the running mobile networks that generate huge data can be the best social sensor for these studies. This paper investigates a practical case of mobile network aided...
In Web database integration, crawling data pages is important for data extraction. The fact that data are contained by multiple result pages increases the difficulty of accessing data for integration. Thus, it is necessary to accurately and automatically crawl query result pages from Web database. To address this problem, we propose a novel approach based on URL classification to effectively identify...
Based on management features of digital mine, this paper makes full use of the spatial data processing of GIS (Geographic Information System) to analyze the module designing and system development of GIS-based mine management information system. It also discusses the spatial data presentation, data manipulation, data queries and data storing in the process of mine management system application.
A method is developed in this paper to reconstruct triangular surface meshes from a bunch of contours. Contours on adjoining slices are decomposed into contour pairs with simple topologies according to the definition of contour distance. Based on the idea of simple constrained triangulation, an revised algorithm is applied for contour pair triangulation and meshes generation. The method presented...
Heroin addiction caused oxidative stress was testified for the first time in mice. After administered with heroin, mice not only showed decreased total antioxidant capacity as well as antioxidant enzymes such as, SOD, CAT and GPx in brain, but also include oxidative damage of DNA, protein and lipid. On the other hand, exogenous antioxidants could restrain the oxidative stress, even alleviate withdrawal...
Taking the estimation of area-percent about different land use in certain city as an example, we evaluated the effect of simple random sampling, stratified sampling based on administrator region, stratified sampling based on knowledge and stratified-systematic sampling based on spatial autocorrelation. Sample size and precision (standard deviation) were made decision criteria to estimate the effect...
