Data warehouses (DW) are built by gathering information from several information sources (ISs) and integrating it into one repository customized to users' needs. Recent work has begun to address the problem of view maintenance of DWs under concurrent data updates of diierent ISs. SWEEP proposed by Agrawal et al. AAS97] is one of the more popular solutions;(More)
Based on the user-centric paradigm for next generation networks, this paper describes a ubiquitous mobile healthcare (uHealth) system based on the ISO/IEEE 11073 personal health data (PHD) standards (X73) and cloud computing techniques. A number of design issues associated with the system implementation are outlined. The system includes a middleware on the(More)
Including dynamic, rather than static, graphs and tables in presentations can make them more effective, interactive and audience-engaging. The SAS ® GIFANIM device enables analysts to create GIF file-based slide shows for web and PowerPoint presentations, but it only supports device-based graphics and does not support SG procedure graphics. The GIFANIM(More)
Designing and implementing a large-scale parallel system can be time-consuming and costly. It is therefore desirable to enable system developers to predict the performance of a parallel system at its design phase so that they can evaluate design alternatives to better meet performance requirements. Before the target machine is completely built, the(More)
A novel clustering algorithm is proposed and applied to the multi-item replenishment processing. This new algorithm has two distinguished features: non-binary hierarchical tree and the feature of overlapping clustering. A non-binary hierarchical tree is much smaller than the binary-trees constructed by most traditional algorithms and, therefore, it clearly(More)
