Item An efficient linear numerical scheme for the Stefan problem, the porous medium equation and nonlinear cross-diffusion systems(SPEKTRUM STU Publishing, 2017-12-29) Molati, M.; Murakawa, H.This paper deals with nonlinear diffusion problems which include the Stefan problem, the porous medium equation and cross-diffusion systems. We provide a linear scheme for these nonlinear diffusion problems. The proposed numerical scheme has many advantages, namely, it is very easy-to-implement, the ensuing linear algebraic systems are symmetric, it requires low computational cost, the accuracy is comparable to that of the well-studied nonlinear schemes, the computation is much faster than the nonlinear schemes to obtain the same level of accuracy. In this paper, numerical experiments are carried out to demonstrate efficiency of the proposed scheme.Item Symmetry classification of coupled heat-diffusion systems via low dimensional Lie algebras(World Scientific Publishing, 2013) Mahomed, F.M.; Molati, M.We review second-order system of coupled heat-diffusion equations. The system under consideration contains several arbitrary elements the forms of which are specified via the method of group classification based on the use of low-dimensional Lie algebras. We collect and present several results.Item Software Support for Creating Digital Health Training Materials in the Field(University of Cape Town, 2013) Molapo, M.; Marsden, G.In this paper, we present the design, implementation, and deployment of a tool developed to help rural health trainers to create digital training content for low-literate Community Health Workers (CHWs) in Lesotho; the digital content being mobile videos created from combining images, voice-over, and/or video clips. Our results show that when health professionals who are based in rural areas were empowered by the tool to create their own content, they were able to supplement nationally and globally produced health training materials with more locally relevant content that addresses unique information needs within their communities. We discuss other lessons learned from an eight-months deployment of this tool in Lesotho, and conclude with recommendations on how a similar project can be implemented in other developing regions.Item Health Education in Rural Communities with Locally Produced and Locally Relevant Multimedia Content(University of Cape Town, 2013) Molapo, M.; Marsden, G.Health education in rural communities is one of the main ways in which developing countries are addressing prevalent health issues like maternal and child mortality, HIV/Aids, tuberculosis (TB) and malaria. In many rural villages, Community Health Workers (CHWs) act as proxies through which health education information is spread in their communities. In this paper, we discuss important principles to consider when designing solutions for creating and distributing digital health content in rural communities, based on previous work in the area of health education and the training of CHWs. We then introduce our model of content creation and distribution, which involves providing tools that allow rural health professionals to independently create health content from within their local communities. We also present the lessons learned from our deployment of this model in Lesotho - highlighting the opportunities presented by the use of locally produced hence locally relevant digital content in health education.Item Planning & Settlement Upgrading In Maseru(2014) Leduka, R.
