(ACM, 2013)
The computing for development community knows how to build user interfaces using qualitative methods for text il- literate users, especially on mobile devices. However, lit- tle work has been done speci cally targeting ...
A novel document ranking algorithm that supports mobile healthcare information access effectiveness
(Academic Journals Inc., 2011)
This study presented DROPT; an acronym for Document ranking Optmization algorithm approach, a new idea for the effectiveness of meaningful retrieval results from the information source. Proposed method extracted the frequency ...
Situation-aware routing based on link quality for static mesh networks with mobile nodes
(Telkom, 2011)
Situation-aware routing seeks to improve quality of service on hybrid wireless mesh networks by making routing decisions based on the current situation of the network. BATMAN-adv is a mesh routing protocol that counts ...
