Tellurium attenuation of kesterite band-gap for improved photovoltaic efficiency
(University of the Western Cape, 2019)
Tellurium is a member of the chalcogen group in the periodic table and is known to be a better semiconductor material when compared to sulfur and selenium. By introducing tellurium into the kesterite structure there would ...
Spectroscopy of proton unbound states in 32Cl
(University of the Western Cape, 2019)
This project aimed to investigate proton unbound states in 32Cl
using the 32S(3He; t) charge-exchange reaction. This research is
relevant both in the context of nuclear structure and astrophysics.
Excited states in 32Cl ...
The paradox of enrichment in predator-prey systems
(University of Western Cape, 2020)
In principle, an enrichment of resources in predator-prey systems show prompts
destabilisation of a framework, accordingly, falling trophic communication, a phenomenon
known to as the \Paradox of Enrichment" [54]. After ...
South African Sign Language Recognition Using Feature Vectors and Hidden Markov Models
(University of the Western Cape, 2010)
This thesis presents a system for performing whole gesture recognition for South African Sign Language. The system uses feature vectors combined with Hidden Markov models. In order to construct a feature vector, dynamic ...
Evaluation of reporting all types of adverse drug reactions by parents of children younger than 18 years in South Africa
(University of the Western Cape, 2019)
Introduction: Medicines are created with the intention of helping patients but may be harmful to the patient by causing adverse reactions. The effect of adverse drug reactions (ADRs) on patients has become more evident ...
Missing imputation methods explored in big data analytics
(University of the Western Cape, 2018)
The aim of this study is to look at the methods and processes involved in imputing missing data and more specifically, complete missing blocks of data. A further aim of this study is to look at the effect that the imputed ...
Medicinal uses of Galenia africana: A study of the antimicrobial, antifungal and anticancer properties
(University of the Western Cape, 2018)
Medicinal uses of Galenia africana: A study of the antimicrobial, antifungal and anticancer properties
Over the years, microorganisms have become resistant to commonly used antimicrobial agents leading to multidrug resistance. ...
Methylgyoxal signalling in Phaseolus vulgaris under phosphate deficiency
(UWC, 2020)
In this study, we observed that phosphate (P) deficiency stunted plant growth and produced plants with poor morphological characteristics (yellow and small leaves). Furthermore, we treated plants with 0.8 mM (control) and ...
The ecohydrology of the Fransehoek Trust Wetland: water, soils and vegetation.
(University of the Western Cape, 2010)
The research was driven by a need to increase the knowledge base concerning wetland ecological
responses, as well as to identify and evaluate the factors driving the functioning of the
Franschhoek Trust Wetland.
An ...
Towards stimuli-responsive functional nanocomposites: Smart tunable plasmonic nanostructures au-v02
(University of the Western Cape, 2010)
The fascinating optical properties of metallic nanostructures, dominated by collective
oscillations of free electrons known as plasmons, open new opportunities for the
development of devices fabrication based on noble ...
