As more and more organizations and individuals tend to outsource their data to cloud storage, the security and user privacy protection attract more attention. Previous work mostly focused on the user identity authentication to keep the security, while in this paper, a novel model of cloud secure storage is proposed, which combines the Hadoop distributed file system(HDFS) with symmetric and public-key...
The three-dimensional integrated modeling of Coal Mine surface and subsurface has a widely needs and applications. It becomes one of important research issues inland and overseas. In view of the deficiencies of present modeling methods, an integrated model based on GTP data model is presented. It applies ground engineering, terrain, geological body, underground engineering model and be comprised of...
3D geological modeling is an important research issue with the studying of the digital city in china. In view of the deficiencies of present modeling methods, a new method to model 3D geological body including faults based on generalized tri-prism (GTP) model is presented. Four geological knowledge inference rules about 3D geological modeling are put forward. The method mainly includes three steps:...
Today the serious casualties of Chinese coal mines happened frequently and caused great casualties and property losses. This situation is extremely associated with scarcity of advanced emergency management(EM) methods for emergences forecast & precaution and decision-making. Data integration of coal mine safety production (CMSP) system is the foundation of solving above problems. According to...
Relevance vector machines have been successfully used in many domains, while their application in software reliability prediction is still quite rare. We proposed an RVM-based model for software reliability prediction, the RVM learning scheme is applied to the failure time data, forcing the network to learn and recognize the inherent internal temporal property of software failure sequence in order...
