The efficiency of drinking water treatment plants in removing immunotoxins
(University of the Western Cape, 2010)The aim of this study was to evaluate the effectiveness of water treatment processes of two drinking water plants to remove immunotoxins and steroid hormones. Raw and treated drinking water was screened for effects on ... -
Efficient Monte Carlo methods for pricing of electricity derivatives
(University of the Western Cape, 2012)We discuss efficient Monte Carlo methods for pricing of electricity derivatives. Electricity derivatives are risk management tools used in deregulated electricity markets. In the past,research in electricity derivatives ... -
Efficient numerical methods based on integral transforms to solve option pricing problems
(University of the Western Cape, 2012)In this thesis, we design and implement a class of numerical methods (based on integral transforms) to solve PDEs for pricing a variety of financial derivatives. Our approach is based on spectral discretization of the ... -
Efficient numerical methods to solve some reaction-diffusion problems arising in biology
(2013)In this thesis, we solve some time-dependent partial differential equations, and systems of such equations, that governs reaction-diffusion models in biology. we design and implement some novel exponential time differencing ... -
Efficient Variable Mesh Techniques to solve Interior Layer Problems
(University of Western Cape, 2020)Singularly perturbed problems have been studied extensively over the past few years from different perspectives. The recent research has focussed on the problems whose solutions possess interior layers. These interior ... -
Effluent water treatment utilising a combination of hydrodynamic shear and flotation technology for the specific application of wastewater from the oil and gas industry
(University of the Western Cape, 2022)Water plays an important role in the petrochemical production and refining processes. The wastewaters released by these processes are often rich in petroleum pollutants, that requires significant treatment prior to ... -

eLearning adoption in Eastern and Southern African higher education institutions
(University of the Western Cape, 2011)This research was undertaken to propose a model for eLearning adoption in Higher Education in Africa and to identify and empirically test measures to assess the model. The model identified eLearning, individual and ... -
Election promises and public policy: Never the twain shalt meet? the case of housing.
(University of the Western Cape, 2000)This research report examines whether election promises find their way into public policy. This question has a particular significance for a fledgling democracy such as South Africa's. During the run-up to South Africa's ... -
Electrical resistivity of the kondo systems (Ce1−xREx)In3, RE = Gd, Tb, Dy AND Ce(Pt1−xNix)Si2
(University of the Western Cape, 2008)The present study investigates the strength of the hybridization by substituting Ce atom in Kondo lattice CeIn3 with Gd, Tb, and Dy and by changing the chemical environment around the Ce atom in substituting Pt with Ni in ... -
Electro chemiluminescence and organic electronics of derivatised poly(aniline sulphonic acid) light-emitting diodes
(University of the Western Cape, 2011)Electrochemiluminescence (EeL) is applied for industrial applications that have considerable potential, such as clinical diagnostic, analytical chemistry, and light-emitting devices, due to selectivity, sensitivity for ... -
Electro sequence analysis and sequence stratigraphy of wells EM1, E-M3 and E-AB1 within the central Bredasdorp Basin, South Africa
(University of the Western Cape, 2015)The study area for this thesis focuses on the central northern part of the Bredasdorp Basin of southern offshore South Africa, where the depositional environments of wells E-M1, E-M3 and E-AB1 were inferred through electro ... -
