Automatic programming assessment has recently become an important method in assisting lecturers and instructors of programming courses to automatically mark and grade students' programming exercises as well as to provide useful feedbacks on students' programming solutions. As part of the method, test data generation process plays as an integral part to(More)
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)
Software engineering is one of the most demanding jobs in software industry nowadays and its demand keeps on increasing. However, there are several issues arise with regard to readiness of Information Technology (IT) or Computer Science (CS) graduates from the point of views of software industry. This perspective causes the supply of graduates mainly in(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)
Adopting design pattern while designing web applications can promote reusability and consistency of the web application. Without the adoption of design patterns or wrong selection of them will make the development of web application more complex and hard to be maintained. Thus knowledge in design patterns is essential in selecting the most appropriate(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)
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 This is more crucial when they need to maintain a software system with outdated documentation or without system documentation at all.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)

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 sets (RS) and RS based inductive learning in reducing the size of rules to be stored in mobile devices. The conditional attributes such as 'timestamp', 'size document'(More)
