  • Yi, Long; Connan, James (Association for Computing Machinery, 2007)
    Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ...
  • Yi, Long; Tucker, William D. (Telkom, 2008)
    This paper describes Kiara, an open source SIPbased communication system that provides the building blocks to enable Deaf relay services. We have implemented a prototype that provides real-time text, voice and video to a ...
  • Chininthorn, Prangnat; Glaser, Meryl; Freudenthal, Adinda; Tucker, William D. (IIMC International Information Management Corporation, 2012)
    This paper presents a case for iterative community-based co-design to facilitate the emergence of an innovative mobile system to address a potentially life-threatening scenario for Deaf people in South Africa. For Deaf ...
  • Mutemwa, Muyowa; Tucker, William D. (Telkom, 2010)
    This paper describes how a deaf to hearing communication aid built for a mobile phone can be used to provide semi-synchronous communication between a Deaf person and a hearing person who cannot sign. Deaf people with access ...
  • Adesina, Ademola Olusola; Nyongesa, Henry O. (Telkom, 2013)
    Patients using the Mobile-Health Information System can send SMS requests to a Frequently Asked Questions (FAQ) web server with the expectation of receiving an appropriate feedback on issues that relate to their health. ...
  • Tiemeni, Ghislaine L. Ngangom; Venter, Isabella M.; Rey-Moreno, Carlos; Tucker, William D. (Telkom, 2013)
    This work in progress paper presents an overview of the development of an efficient and accurate mobile traffic generator based on an open source computer-based traffic generator software. A high performance mobile traffic ...
  • Chitedze, Zimani; Tucker, William D. (Telkom, 2011)
    This paper addresses mobility management issues in an environment with both wireless LAN and wireless mesh networks. We first examine wireless mesh network client side transparency within mesh mobility management protocols ...
  • Tucker, William D.; Vuza, Xolisa; Chetty, Marshini; Blake, Edwin H.; Marsden, Gary; Pearson, Murray; Westerveld, Rudi (2007)
    For four years we have been iteratively evolving MUTI, a rural telehealth system, for hospitals and clinics in a remote rural part of the Eastern Cape in South Africa (Chetty, 2005; Chetty et al., 2003, 2004a; Maunder et ...
  • Agbele, Kehinde K.; Adesina, Ademola Olusola; Nyongesa, Henry O.; Febba, Ronald (Medwell Journals, 2010)
    The significant roles play by ranking function in the performance and success of Information Retrieval (IR) systems and search engines cannot be underestimated. Diverse ranking functions are available in IR literature. ...
  • Agbele, Kehinde K.; Adesina, Ademola Olusola; Azeez, Nureni A.; Abidoye, Ademola P.; Febba, Ronald (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 ...
  • Tucker, William D.; Blake, Edwin H.; Marsden, Gary (Telkom, 2004)
    We looked for and found two situations within the South African Digital Divide where constant and severe macro-scale latencies would most likely interfere with the usage of Information and Communication Technology (ICT) ...
  • Rey-Moreno, Carlos; Tucker, William David; Simo-Reigadas, Javier (Telkom SA, 2014)
    This paper presents the business context and results of an optimisation exercise for a single-radio mid-range multi-hop wireless mesh network for the provision of VoIP services. This WiFi mesh network physically covers 30 ...
  • Ufitamahoro, Marie Josee; Venter, Isabella; Rey-Moreno, Carlos; Tucker, William David (ACM, 2014)
    This paper describes the role participatory design can play in developing and implementing an information and communication technology for development project in a rural area. It shows how the process of co-designing an ...
  • Azeez, Nureni A.; Abidoye, Ademola P.; Adesina, Ademola Olusola; Agbele, Kehinde K.; Iyamu, Tiko; Venter, Isabella M. (Akamai University, 2011)
    Currently, both Peer-to-Peer Computing (P2P) and Grid Computing have remained the most vibrant and useful forms of distributed computing all over the world. Their applications are such that they cut across both academia ...
  • Tiemeni, Ghislaine Livie Ngangom; Venter, Isabella; Tucker, William David (ACM, 2014)
    The problem of generating different patterns of traffic to emulate real user behaviour is receiving considerable attention with the construction of new and more complex network architectures. The theoretical modelling of ...
  • Bidwell, Nicola J.; Lalmas, Mounia; Marsden, Gary; Dlutu, Bongiwe; Ntlangano, Senzo; Manjingolo, Azola; Tucker, William D.; Jones, Matt; Robinson, Simon; Vartiainen, Elina; Klampanos, Iraklis (Product & Systems Internationalisation, Inc, 2011)
    Designers and developers are naïve about the ways impoverished people in rural Africa innovate new uses of mobile technology to circumvent access difficulties. Here, we report on the local appropriation of an USSD ‘Callback’ ...
  • Naidoo, Vaughn; Tucker, William D. (Telkom, 2001)
    Next Generation Networks use policy-based network management and QoS protocols to provide voice services on IP networks. Large numbers of older equipment still push IP packets. We present several solutions that include ...
  • Glaser, Meryl; Tucker, William D.; Mashao, Daniel (Telkom, 2004)
    Following on the development of several prototypes, we have built a semi-automated Deaf Telephony prototype on the SoftBridge platform. This prototype relays text and speech between Deaf users on the Internet and hearing ...
  • Adesina, Ademola Olusola; Agbele, Kehinde K.; Azeez, Nureni A.; Abidoye, Ademola P. (Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd., 2011)
    Mobile technology has contributed to the evolution of several media of communication such as chats, emails and short message service (SMS) text. This has significantly influenced the traditional standard way of expressing ...
  • Segers, Vaughn; Connan, James (2009)
    This paper discusses an implementation for gesture recognition using eigenvectors under controlled conditions. This application of eigenvector recognition is trained on a set of defined hand images. Training images are ...
