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 ...
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 ...
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. ...
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 ...
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 ...
Improving usability and correctness of a mobile tool to help a Deaf person with pharmaceutical instruction
(ACM, 2013)
The computing for development community knows how to build user interfaces using qualitative methods for text il- literate users, especially on mobile devices. However, lit- tle work has been done speci cally targeting ...
A novel document ranking algorithm that supports mobile healthcare information access effectiveness
(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 ...
Situation-aware routing based on link quality for static mesh networks with mobile nodes
(Telkom, 2011)
Situation-aware routing seeks to improve quality of service on hybrid wireless mesh networks by making routing decisions based on the current situation of the network. BATMAN-adv is a mesh routing protocol that counts ...
Asynchronous video telephony for the Deaf
(Telkom, 2007)
The South African Deaf community has very limited telephony options. They prefer to communicate in sign language, a visual medium. Realtime video over Internet Protocol is a promising option, but in reality, the quality ...
