Mn nanoparticles encapsulated within mesoporous helical n-doped carbon nanotubes as highly active air cathode for zinc–air batterie
(Wiley Online Library, 2019)The practical application of clean energy conversion and storage technologies, such as fuel cells and metal–air batteries, have been significantly impeded by the high cost and scarcity of precious metal catalysts used for ... -
Mobile Communication Tools for a South African Deaf patient in a pharmacy context
(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 ... -
A mobile Deaf-to-hearing communication aid for medical diagnosis
(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 ... -
A mobile platform traffic generator for network performance evaluation
(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 ... -
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 ... -
Mobile vertical handover between infrastructure and ad hoc Wi-Fi networks
(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 ... -
Mobile video comparison to help Deaf people make informed choices: a South African case study with provincial data
(IIMC International Information Management Corporation, 2018)Deaf people use sign language to communicate and use mobile video calling to communicate with one another. Mobile video utilises much more bandwidth than text and voice communication modes, resulting in higher expenditure ... -
A Mobile-Health Information Access System
(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. ... -
A model for control of HIV/AIDS with parental care
(World Scientific Publishing, 2013)In this study we investigate the HIV/AIDS epidemic in a population which experiences a significant flow of immigrants. We derive and analyze a mathematical model that describes the dynamics of HIV infection among the ... -
Model of compact star with ordinary and darkmatter
(Springer Nature, 2020)We study compact stars formed by dark and ordinary matter, with attributes of both neutron star matter and quark star matter. We assume an equation of state for dark matter which is consistent with the rotational ... -
A model of HIV/AIDS population dynamics including ARV treatment and pre-exposure prophylaxis
(SpringerOpen, 2018)Antiretroviral treatment (ART) and oral pre-exposure prophylaxis (PrEP) have recently been used efficiently in management of HIV infection. Pre-exposure prophylaxis consists in the use of an antiretroviral medication to ... -
A model of malaria population dynamics with migrants
(Mathematical Biosciences and Engineering, 2021-08)We present a compartmental model in ordinary differential equations of malaria disease transmission, accommodating the effect of indoor residual spraying on the vector population. The model allows for influx of infected ... -
A model of population dynamics of TB in a prison system and application to South Africa
(BioMed Central, 2017)BACKGROUND: Tuberculosis (TB) continues to spread in South African prisons in particular, as prisons are over-capacitated and have poor ventilation. The awaiting trial detainees are not screened on admission and are at ... -
Model-independent constraints on dark energy and modified gravity with the SKA
(Proceedings of Science, 2014)Employing a nonparametric approach of the principal component analysis (PCA), we forecast the future constraint on the equation of state w(z) of dark energy, and on the effective Newton constant m(k; z), which parameterise ... -
Modeling the dynamics of an epidemic under vaccination in two interacting populations
(Hindawi, 2012)Mathematical modeling of the numerical evolution of infectious diseases has become an important tool for disease control and eradication when possible. Much work has been done on the problem of how a given population is ... -
Modeling the geographic spread and proliferation of invasive alien plants (IAPs) into new ecosystems using multi-source data and multiple predictive models in the Heuningnes catchment, South Africa
(Taylor and Francis, 2021)The geographic spread and proliferation of Invasive Alien Plants (IAPs) into new ecosystems requires accurate, constant, and frequent monitoring particularly under the changing climate to ensure the integrity and resilience ... -
Modeling the impact of combined use of Covid Alert SA app and vaccination to curb Covid-19 infections in South Africa
(Public Library of Science, 2023)The unanticipated continued deep-rooted trend of the Severe Acute Respiratory Syndrome Corona-virus-2 the originator pathogen of the COVID-19 persists posing concurrent anxiety globally. More effort is affixed in the ... -

A modelling approach to improving water security in a drought-prone area, West Coast, South Africa
(ScienceDirect, 2019)Due to severe droughts and rapid urbanization, Cape Town municipality including small towns along the West Coast of South Africa are facing water shortages. Managed aquifer recharge (MAR) seems to offer a solution to improve ... -
Modelling human protein interaction networks as metric spaces has potential in disease research and drug target discovery
(BMC, 2014)We have recently shown by formally modelling human protein interaction networks (PINs) as metric spaces and classified proteins into zones based on their distance from the topological centre that hub proteins are primarily ...
