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 ... -
Thoughts on the future of higher education in the UK: A personal view with a historical context
(MPDI, 2021)Before the effect of the COVID-19 Pandemic, there had been continued debate about the future of Higher Education (HE) in the UK. It is now accepted that the effect of the pandemic will have a long-lasting effect on HE ... -
A mobile survey for collecting data from deaf people who use sign language for communication
(Institute of Electrical and Electronics Engineers Inc, 2021)Hearing researchers and practitioners might have encountered challenges in collecting data from Deaf people who mainly rely on sign language for communication. This could be due to language barriers and the non-user-friendly ... -
Intelligent transportation related complex systems and sensors
(MPDI, 2021)Building around innovative services related to different modes of transport and traffic management, intelligent transport systems (ITSs) are being widely adopted worldwide to improve the efficiency and safety of the ... -
Emotion and stress recognition related sensors and machine learning technologies
(MPDI, 2021)Intelligent sociotechnical systems are gaining momentum in today’s informationrich society, where different technologies are used to collect data from such systems and mine this data to make useful insights about our ... -
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, ... -
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 ... -
Water distribution network leak detection management
(Curran Associates Inc., 2020)Water is becoming an increasingly scarce commodity and must be effectively managed to ensure minimal losses. Water is a basic human resource and during both a physical and a cyber war, limiting, or interrupting the supply ... -
An ontology for the south african protection of personal information act
(Curran Associates Inc., 2020)The protection and management of data, and especially personal information, is becoming an issue of critical importance in both the business environment and in general society. Various institutions have justifiable reasons ... -
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. ... -
Complex sequential data analysis: A systematic literature review of existing algorithms
(SAICSIT, 2020)This paper provides a review of past approaches to the use of deep-learning frameworks for the analysis of discrete irregularpatterned complex sequential datasets. A typical example of such a dataset is financial data ... -
Video Relay Service for Deaf people using WebRTC
(University of the Western Cape, 2019-03)This paper reports on an experimental open source video relay service prototype that helps Deaf people communicate with hearing people by accessing a third party sign language interpreter on a mobile device. Deaf people ... -
Challenges for the adoption of ICT for diabetes selfmanagement in South Africa
(University of the Western Cape, 2019)The increasing disease burden in developing countries inhibits the provision of quality care to citizens. However, the increased availability of information communication and technology (ICT) tools makes this a viable ... -
Evaluating energy consumption on low-end smartphones
(2015)The relationship between battery consumption in smartphones and the usage statistics of a phone is direct. Modern smartphones, even low-end, are equipped with multiple wireless technologies, e.g. GSM, 3G, WiFi and ... -
Investigating battery consumption in low- end smartphones: preliminary results
(International Information Management Corporation, 2017)Due to lack of electricity in the rural communities of Africa, users often have to incur extra expense on recharging their mobile phones. The limited battery capacities of low-end smartphones, therefore, present a barrier ... -
Investigation of a dual-band dual radio indoor mesh testbed
(2018)Scalability of community wireless mesh networks in terms of mesh nodes and mobile end-users along with their anticipated usage profile remains unexplored territory. However, conducting such experiments on a live community ... -
Internet-of-Things in motion: A UAV coalition model for remote sensing in smart cities
(MDPI AG, 2018)Unmanned aerial vehicles (UAVs) or drones are increasingly used in cities to provide service tasks that are too dangerous, expensive or difficult for human beings. Drones are also used in cases where a task can be performed ... -
A comprehensive survey on Fog Computing: State-of-the-art and research challenges
(IEEE, 2018)Cloud computing with its three key facets (i.e., Infrastructure-as-a-Service, Platform-as-a-Service, and Softwareas- a-Service) and its inherent advantages (e.g., elasticity and scalability) still faces several challenges. ... -
Towards a model for user-centred design using a positive deviance approach: A case for diabetes self-management
(University of Cape Town, 2017)Over the past twenty years there have been substantive efforts across the African continent to ensure penetration and reach of mobile technology to the citizenry. However there continues to be a debate on precisely how ...
