Massive amounts of multimedia data (i.e., text, audio, video, graphics and animation) are being generated everyday. Conventionally, managed by the platforms maintained service providers, which generally designed using centralised architecture. However, such architecture may lead to a single point failure disputes over royalties or other rights. It is hard ensure integrity track fulfilment oblig...

Content syndication specifications such as Atom have become a popular mechanism to disseminate information across the Internet, with many sites providing Atom feeds for users to subscribe to and consume. Such a scenario typifies the originally intended use of Atom; however, our research has explored an alternative domain for this syndication technology. This research has evaluated Atom for its ...

The explosive growth of scientific visualization in the past 10 years demonstrate a consistent and tacit agreement among scientists that visualization offers a better representation system for displaying complex data than traditional charting methods. However, most visualization works have not been unable to exploit the full potential of visualization techniques. The reason may be that these at...

We present incremental view maintenance algorithms for a data warehouse derived from multiple distributed autonomous data sources. We begin with a detailed framework for analyzing view maintenance algorithms for multiple data sources with concurrent updates. Earlier approaches for view maintenance in the presence of concurrent updates typically require two types of messages: one to compute the ...

Large numbers of low-cost, low-reliability commodity components are rapidly replacing high-quality, mainframe-class systems in data centers. These commodity clusters are far less expensive than the systems they replace, but they can bring new administrative costs in addition to heat and power-density challenges. This proposal introduces a data center architecture based upon macro-modules of sta...
