A cloud computing prototype system, UbiCloud, is developed to enable the ubiquitous terminals access to powerful and reliable computing resources anywhere and anytime through building a virtual computing environment between the front-end ubiquitous terminals and the back-end servers (cloud). The experiment results show that the system performance is good enough to support most applications deployment...
Polymorphism is one of the three most important characters of object-oriented technology. Not only it enhances the flexibility of programming and reused of codes, but also it brings new challenge for the software testing. After analyzing the software UML model document, we represent it in XML form. And then, under the guidance of control-flow graph, we integrated class diagram's information with collaboration...
MODIS (Moderate Resolution Imaging Spectroradiometer) is an advance earth observation system, which is the world's best remote sensing data of free receiving. However, there is a serious problem about duplicated establishment of MODIS data receive station in China, and it has brought a tremendous waste of money. Utilizing data grid technology could take advantages to integrate and share heterogeneous...
The research purchases more orders to the geo-computation data infrastructure. It should be distributed, platform-independent, extensible, robust, and can one-stop serve the applications. In this paper, based on grid technology, an SOA based 4-layered data infrastructure which is built up by data nodes, data sources, data agencies, client libraries, and other components is proposed. It adopts an XML...
The continuing research on geo-computation purchases more orders to the data infrastructure of geo-computation. It should be distributed, platform-independent, extensible, robust, autonomic, and can on-stop serve the users and applications. In this paper, based on spatial information grid (shortly SIG), a 4-layered data infrastructure which is built up by data nodes, data sources, data agencies, support...
