Web Usage mining, also known as Web Log mining, is an application of data mining algorithms to Web access logs to find trends and regularities in Web users' traversal patterns. The results of Web Usage Mining have been used in improving Web site design, business and marketing decision support, user profiling, and Web server system performance. Web page(More)
In this paper, we consider the problem of data sharing in scientific workflows running on the cloud. We present the design and evaluation of a peer-to-peer approach to help solve this problem. We compare the performance of our peer-to-peer file manager with that of two network file systems for storing data for a typical data-intensive workflow application.(More)
Finding relevant information on the web is an ongoing problem. Commercial search engines like Google rely on sophisticated algorithms to index huge collection of web pages to make them accessible to user queries. Users, however, are still frequently overloaded with irrelevant results. The required information is available in replicated manner scattered in(More)
Superparamagnetic iron oxide nanoparticles (SPIONs) have attracted increasing attention in many biomedical fields. In magnetic drug targeting SPIONs are injected into a tumour supplying artery and accumulated inside the tumour with a magnet. The effectiveness of this therapy is thus dependent on magnetic properties, stability and biocompatibility of the(More)
Most of the communications in the century is accomplished through the wireless medium. There are various standards for simultaneous running of different applications. WLAN (Wireless Local Area Network) is a common wireless communication standard. Among the five bands announced by IEEE in 802. 11 standards for wireless LAN, two most common bands are 2. 4 GHz(More)
