Floor control arbitration for a hybrid voice/text web-board
(Telkom, 2003)We have built a hybrid voice/text web–board that utilizes floor control for handling resources such as microphone and interface events. The aim of this research is to determine the most appropriate floor control mechanism ... -
A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks
(Telkom, 2000)The multi-service, multi-architecture nature of NGNs is so complex that the management of services, in addition to networks, emerges as a research challenge. Despite QoS limitations, VoIP (as opposed to VoATM), dominates ... -

Grafting an ATM network onto an existing ethernet network
(Telkom, 1998)Grafting an ATM network onto an existing Ethernet network is a non-trivial exercise in network configuration. The process of mating ATM technology to an Ethernet network without tampering the underlying backbone and network ... -
Granny gets smarter but junior hardly notices
(College of Communication and Information, 2016)To ensure that university computing students are sensitized to the needs of diverse user groups, a course project was designed to allow students to get a realistic understanding of the needs and abilities of the older ... -
Groundwater prediction using machine-learning tools
(MPDI, 2020)Predicting groundwater availability is important to water sustainability and drought mitigation. Machine-learning tools have the potential to improve groundwater prediction, thus enabling resource planners to: (1) anticipate ... -
Guaranteed delivery of semi-synchronous IP-based communication
(Telkom, 2004)This research aims to find an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IP-based communication domain. The communication infrastructure that is ... -
Guaranteed delivery of semi-synchronous IP-based communication
(Telkom, 2005)This paper presents an empirical solution for guaranteeing the delivery of synchronous and asynchronous messages within a semi-synchronous IPbased communication domain. The communication infrastructure that is needed between ... -
Handheld fast-track feedback instant messaging
(Telkom, 2003)As mobile devices and networks become more data-centric, text messaging requires an extension of co-presence capabilities for better interactive discussion between input/output handicapped handheld users and their free ... -
Higher education students’ perceptions of online learning during Covid-19—A comparative study
(MPDI, 2021)The pandemic and subsequent ‘lockdowns’ dramatically changed the educational landscape of higher education institutions. Before-COVID-19, traditional universities had choices in pedagogical practice, which included a ... -
