• Ideals of function rings associated with sublocales 

  Stephen, Dorca Nyamusi (2021-03)

  The ring of real-valued continuous functions on a completely regular frame L is denoted by RL. As usual, βL denotes the Stone-Cech compactification of ˇ L. In the thesis we study ideals of RL induced by sublocales of βL. ...
• Mathematical modelling of low HIV viral load within Ghanaian population 

  Owusu, Frank K. (2020-09)

  Comparatively, HIV like most viruses is very minute, unadorned organism which cannot reproduce unaided. It remains the most deadly disease which has ever hit the planet since the last three decades. The spread of HIV has ...
• Towards hybrid stochastic modeling and simulation of complex systems in multi-scale environments with case studies on the spread of tuberculosis in Democratic Republic of the Congo 

  Kabunga, Selain Kasereka (2020-10)

  Mathematical modeling of the spread of infectious diseases in a population has always been recognized as a powerful tool that can help decision-makers understand how a disease evolves over time. With the evolution of science ...
• Spectral factorization of matrices 

  Gaoseb, Frans Otto (2020-06)

  The research will analyze and compare the current research on the spectral factorization of non-singular and singular matrices. We show that a nonsingular non-scalar matrix A can be written as a product A = BC where the ...
• Well-posedness and mathematical analysis of linear evolution equations with a new parameter 

  Monyayi, Victor Tebogo (2020-01)

  In this dissertation we apply linear evolution equations to the Newtonian derivative, Caputo time fractional derivative and $-time fractional derivative. It is notable that the most utilized fractional order derivatives ...
• VLBI Imaging of ICRF Sources in the Southern Hemisphere using Geodetic and Astrometric Observations 

  Basu, Sayan (2020-05)
