— One of the roles of e-government portals is to provide a one-stop service to users. In order to fulfill this role, it requires collaboration with other government agencies and businesses to provide an effective one-stop center for users to access and perform various services. Current e-government portals are mostly lack of interoperability whereby users(More)
Mobile Web pre-caching (Web prefetching and caching) is an explication of performance enhancement and storage limitation of mobile devices. In this paper, we present the granularity of Rough Set (RS) and rough set based inductive learning in reducing the size of rules to be stored in mobile devices. The conditional attributes such as Timestamp, Sizedocument(More)
Web caching is a technology to improve network traffic on the Internet. It is a temporary storage of Web objects for later retrieval. Three significant advantages of Web caching include reduction in bandwidth consumption, server load, and latency. These advantages make the Web to be less expensive yet it provides better performance. This research aims to(More)
The demand for Internet content rose dramatically in recent years. Servers became more and more powerful and the bandwidth of end user connections and backbones grew constantly during the last decade. Nevertheless users often experience poor performance when they access web sites or download files. Reasons for such problems are often performance problems(More)
Visualizing the artifacts of a software system graphically has proven to improve the cognitive strategies and understanding of the subject system by programmers. This is more crucial when they need to maintain a software system with outdated documentation or without system documentation at all. Many tools have emerged and they predominantly consist of a(More)
—This research is intended to improve the 'Theory of Inventive Problem Solving' TRIZ methodology by integrating with the Multi Criteria Decision Making (MCDM) tool; Analytical Hierarchy Process (AHP). This integration works as a support tool to assist the TRIZ practitioners or design engineers. AHP is employed to rank ideas generated by TRIZ in order to(More)
—Both Web caching and pre-fetching is a ubiquitous technique that can increase the speed of Web loading process. As mobile context has limited resources like speed and memory, a better technique for Web loading process is vital. This paper proposes a new technique known as an Intelligent Mobile Web Pre-fetching (IMWeP) that creates pre-fetching in a mobile(More)
E-learning is a one of e-services that has been used in Universiti Teknologi Malaysia (UTM) since 2005 so-called as e-Learning@UTM. The demand for e-learning content rose dramatically in every semester. The e-learning servers became graver during the increasing number of users for each semester. Nevertheless users often experience poor performance when they(More)
Understanding an existing software system to trace possible changes involved in a maintenance task can be time consuming especially if its design document is absence or outdated. In this case, visualizing the software artefacts graphically may improve the cognition of the subject system by software maintainers. A number of tools have emerged and they(More)
