Current e-learning systems are primarily resource oriented, rather than cognition oriented. To reduce learners' cognitive overload in e-learning, we proposed a novel e-learning system Yotta tackling the problem of knowledge acquisition, knowledge presentation, and knowledge resources management. The granularity for knowledge acquisition in Yotta is based on knowledge units that are the smallest integral...
A Data Warehouse (DW) is characterized by a huge amount of data centralized in a single database. This centralization has negative impacts on its performance especially for distributed companies; such us elevated storage cost, high query execution time and hard maintenance task. Since a relational data warehouse has the same physical structure as a classical database, it can enjoy all the benefits...
We present a service resource selection and scheduling approach capable of maximizing the resource utilization rate (RUT) and the requirement satisfaction degree (RSD) by bundling multiple customer requirements (CRs). In traditional approaches, each CR is optimally satisfied by independently selecting a set of candidate service resources. This possibly leads to a low RUT and low RSD. In our approach,...
OSGi is a widely used service-oriented platform which provides support for the development and execution of component-based e-business applications. The component monitoring of OSGi-based software is important to the software reliability analysis and abnormality diagnosis. However, current approaches not only bring significant overhead, but also lack interaction behavior analysis. This paper focuses...

Archival workflow is a precise representation of the archival process, reflecting the formal coordination mechanisms between archival activities and manual processes with respect to the specific requirements of the local governing body. Understanding key performance indicators of archival processes is considered as...
Cloud computing often uses the multi-tenancy architecture where tenants share system software. To support dynamically increasing demands from multi-tenants, the cloud service providers have to duplicate computing resources to cope with the fluctuation of requests from tenants. This is currently handled by virtualization and duplication at the application level in the existing cloud environment, such...
