  • A tag-like, linked navigation approach for retrieval and discovery of desktop documents 

    Mosweunyane, Gontlafetse; Carr, Leslie; Gibbins, Nicholas (Springer, www.springer.com, 2011)
    Computer systems provide users with abilities to create, organize, store and access information. Most of this information is in the form of documents in files organized in the hierarchical folder structures provided by ...

  • Assessing acceptance of adaptive educational hypermedia systems: prior knowledge vs. cognitive styles 

    Mampadi, F. (International Journal of Computer Science Issues, http://www.ijcsi.org/index.php, 2012)
    Perceived usefulness and ease of use have proved to be key determinants of the acceptance and usage of e-learning systems. On the contrary, little is known about students' perceptions in Adaptive Educational Hypermedia ...

  • Analyzing the load balance of term-based partitioning 

    Abusukhon, A.; Talib, M. (The Science and Information Organization Inc., http://ijacsa.thesai.org/, 2011)
    In parallel (IR) systems, where a large-scale collection is indexed and searched, the query response time is limited by the time of the slowest node in the system. Thus distributing the load equally across the nodes is ...

  • Using merkle tree to mitigate cooperative black-hole attack in Wireless Mesh Networks 

    Om, S.; Talib, M. (The Science and Information Organization Inc., www.ijacsa.thesai.org, 2011)
    Security is always a major concern and a topic of hot discussion to users of Wireless Mesh Networks (WMNs). The open architecture of WMNs makes it very easy for malicious attackers to exploit the loopholes in the routing ...
