(Springer, 2015-09)We present a model of biofilm growth in a long channel where the biomass is assumed to have the rheology of a viscous polymer solution. We examine the competition between growth and erosion-like surface detachment due ...
-
(University of Pretoria, 2018)This dissertation examines the market efficiency and arbitrage opportunities between 04 January 2000 and 31 December 2015 on selected JSE-listed stocks and equity indices. To assess market efficiency, four tests were ...
-
(University of Pretoria, 2019)This study investigates the cryptocurrency called bitcoin. A cryptocurrency is a type of currency that depends on cryptography to issue new units instead of depending on government decree like fiat currencies. The study ...
-
(Springer, 2011)Building on prior joint work by Mallios and Ntumba, we study transvections (J. Dieudonn´e), a theme already important from the classical theory, in the realm of Abstract Geometric Algebra, referring herewith to symplectic ...
-
(Springer, 2014-11)Please read abstract in the article.
-
(Taylor and Francis, 2019)This paper focuses on the students who are registered in the University of Pretoria’s academic development programme, named the Four-year Programme (FYP). The programme was introduced as a gateway for students who are ...
-
(Duke University Press, 2016)This paper provides a semantic analysis of admissible rules and associated completeness conditions for arbitrary deductive systems, using the framework of abstract algebraic logic. Algebraizability is not assumed, so ...
-
(University of Pretoria, 2015)We introduce a new framework of generalized operators to handle vector valued distributions, intertwined evolution operators of B-evolution equations and Fokker Planck type evolution equations. Generalized operators capture ...
-
(University of Pretoria, 2018)In this dissertation, Szemer edi's Theorem is proven using ergodic theoretic techniques via the Furstenberg Multiple Recurrence Theorem. Brief historical remarks, along with a non-technical layout of the ideas behind the ...

Analysis and dynamically consistent nonstandard discretization for a rabies model in humans and dogs (Springer, 2016-09)Rabies is a fatal disease in dogs as well as in humans. A possible model to represent rabies transmission dynamics in human and dog populations is presented. The next generation matrix operator is used to determine the ...
-
(Wiley, 2018-11)Fragmentation‐coagulation processes, in which aggregates can break up or get together, often occur together with decay processes in which the components can be removed from the aggregates by a chemical reaction, evaporation, ...

Analysis of a time implicit scheme for the Oseen model driven by nonlinear slip boundary conditions (Springer, 2016-12)This work is concerned with the time discrete analysis of the Oseen system of equations driven by nonlinear slip boundary conditions of friction type. We study the existence of solutions of the time discrete model and ...
-
(Springer, 2017-04)In this work, four finite volume methods have been constructed to solve the 2D convective Cahn–Hilliard equation with specified initial condition and periodic boundary conditions. We prove existence and uniqueness of ...
-
(Elsevier, 2009)The S-layer differential transform produces subsurface conductivity-depth images from Time Domain Electromagnetic (TDEM) data. It is a very fast method, but suffers from high noise levels due to the implementation of two ...
-
(Taylor and Francis, 2014)In this work, we study Brinkman-Forchheimer equations driven under slip boundery conditions of friction type. We prove the existence and uniqueness of weak solutions by means of regularization combined with the Faedo-Galerkin ...
-
(University of Pretoria, 2006-08-26)Please read the abstract/summary in the section 00back of this document.
-
(University of Pretoria, 2022)Research on vibrations of flexible structures is ongoing in engineering and applied mathematics fields. Flexible structures in practice can be considered as systems of interconnected rod-like components. This dissertation ...
-
(Springer, 2019-01)In the paper we present a survey of recent results obtained by the author that concern discrete fragmentation–coagulation models with growth. Models like that are particularly important in mathematical biology and ecology ...
-
(Elsevier, 2017-10)Angular equivalence is introduced and shown to be an equivalence relation among the norms on a fixed real vector space. It is a finer notion than the usual (topological) notion of norm equivalence. Angularly equivalent ...
-
(University of Pretoria, 2012)This dissertation is based on the papers written by Platen and Rebolledo (1996), and Platen (1999). The papers focuses on modeling the short term interest rate by optimizing relative entropy of two probability measures Q ...
