    Universities are increasingly required to respond to the ever evolving needs of an ever more sophisticated and globalised workplace, which requires well-rounded workers with more than mere technical knowledge. Employers ...
  • Bridging communications across the digital divide 

    Blake, Edwin H.; Tucker, William David (CTIT, 2004)
    Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centered approach to learn how interaction techniques can compensate for poor communication across ...
  • Browser-based sign language communication 

    Wang, Yuan Yuan; Tucker, William David (Telkom, 2010)
    This paper describes the design and evaluation of two browser-based video communication prototypes that support sign language communication between Deaf people. The research explores combinations of technologies, protocols ...

    Zulu, Docas Dudu; Tucker, William David (Telkom, 2010)
    This paper describes work in progress on call capacity optimization for voice over Internet Protocol on wireless mesh networks. In a developing country such as South Africa, evidence has shown that rural inhabitants find ...
  • Candida antifungal drug resistance in sub-Saharan African populations: A systematic review 

    Africa, Charlene Wilma Joyce; Abrantes, Pedro Miguel dos Santos (Science Navigation Group, 2017)
    BACKGROUND: Candida infections are responsible for increased morbidity and mortality rates in at-risk patients, especially in developing countries where there is limited access to antifungal drugs and a high burden of HIV ...
  • Capture zone simulation for boreholes located in fractured dykes using the linesink concept 

    Xu, Yongxin; van Tonder, Gerrit J. (Water Research Commission, 2002)
    Delineation of capture zones for groundwater source protection is normally performed by using numerical codes which are based on the porous medium flow equation. However, boreholes are often sited in or along permeable ...
  • Carbapenem resistance expressed by Gram-negative bacilli isolated from a cohort of Libyan patients 

    Shallouf, Mohamed; Abrantes, Pedro Miguel dos Santos; Africa, Charlene W.J. (BioMed Central, 2016)
