Please call ME.N.U.4EVER: designing for “Callback” in rural Africa
(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’ ... -
Policy-based network management of legacy equipment in Next Generation Networks
(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 ... -
A preliminary study of a graphene fractal sierpinski antenna
(Institute of Physics Publishing, 2020)We provide a preliminary study of a Graphene fractal antenna operating at THz frequencies with the opportunity to modulate the emission. There are many advantages of the fractal design, namely multiband/wideband ability, ... -
Preparation of Deaf end-users and the softbridge for semi-automated relay trials
(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 ... -
A query-based SMS translation in information access system
(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 ... -
Real-time gesture recognition using eigenvectors
(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 ... -
Reflection on three years of rural wireless Internet Protocol communication
(Telkom, 2007)This paper reports on three years of research and fieldwork with a rural wireless Internet Protocol communication project. We built a long-range WiFi network and custom communication software to support a rural telehealth ... -
Regional rainfall prediction using support vector machine classification of large-scale precipitation maps
(Institute of Electrical and Electronics Engineers Inc., 2020)Rainfall prediction helps planners anticipate potential social and economic impacts produced by too much or too little rain. This research investigates a class-based approach to rainfall prediction from 1-30 days in advance. ... -
Relevant computing curricula in Sub-Saharan Africa
(2011)The principle objective of this research was to establish what computing curricula are required for the Sub-Saharan Africa region. Input from academics, businessmen and the analyses of curricula from several African ... -
Reliable communication across ad hoc networks
(Telkom, 2008)This paper presents a fully decentralised peer-topeer voice communication tool intended for use across mobile ad hoc networks (MANET) by distributed groups who desired collaboration. We examined the synergy between MANETs ... -
Renewing Felsenstein’s phylogenetic Bootstrap in the era of big data
(Nature Publishing Group, 2018)Felsenstein’s application of the bootstrap method to evolutionary trees is one of the most cited scientific papers of all time. The bootstrap method, which is based on resampling and replications, is used extensively to ... -
A review of the fractal market hypothesis for trading and market price prediction
(MPDI, 2022)This paper provides a review of the Fractal Market Hypothesis (FMH) focusing on financial times series analysis. In order to put the FMH into a broader perspective, the Random Walk and Efficient Market Hypotheses are ... -
The role of Outcome Mapping in developing a rural telemedicine system
(International Information Management Corporation, 2008)We describe the use of Outcome Mapping to guide the design of a rural telemedicine consultation system in South Africa. While Outcome Mapping was not primarily intended to guide design, we show that it tied in well with a ... -
Rural Wireless Mesh Network Analysis on Mobile Devices
(Telkom SA, 2014)The aim of this research effort is to build an efficient and accurate mobile traffic generator based on open source computer-based traffic generator software. A high performance mobile traffic generator would make the ... -
Secure contactless smart card transactions on mobile devices
