Data mining, fraud detection and mobile telecommunications: call pattern analysis with unsupervised neural networks
(University of the Western Cape, 2005)Huge amounts of data are being collected as a result of the increased use of mobile telecommunications. Insight into information and knowledge derived from these databases can give operators a competitive edge in terms of ... -
Data Science techniques for predicting plant genes involved in secondary metabolites production
(University of the Western Cape, 2018)Plant genome analysis is currently experiencing a boost due to reduced costs associated with the development of next generation sequencing technologies. Knowledge on genetic background can be applied to guide targeted ... -
Deciphering a potential cytoprotective role of novel heat shock responsive proteins using a proteomic approach
(University of the Western Cape, 2011)Myocardial infarction, commonly known as a heart attack, is a condition where the blood supply to the heart tissue is cut off, starving the tissue from oxygen and nutrient supply, with consequent lethal damage to the heart ... -
Defining the African green monkey (Chlorocebus Aethiops): expression behaviour of selected lipid metabolism genes in response to niacin
(University of Western Cape, 2012)In this century most major medical advances have resulted in part from research on animals and non-human primates such as the African green monkey and therefore often serve as a critical link between basic research and ... -
Degradation of bisphenol-a and 2-Nitrophenol by combined advanced oxidation technologies
(University of the Western Cape, 2015)Emerging micropollutants such as bisphenol-A and 2-nitrophenol present a great threat in drinking water due to their adverse effects. Most conventional technologies in water and wastewater treatment are not designed to ... -
Degradation of persistent organic pollutants (pharmaceuticals & dyes) by combined dielectric barrier electrohydraulic discharge system and photo catalysts
(University of the Western Cape, 2019)Water pollution problems have continued to increase not only in South Africa but worldwide due to human activities. The presence of organic toxins and bacteria in water sources is mostly due to population growth, industrial ... -
The degradation of the endocrine disrupting chemical, bisphenol-A : a comparative study between fungal and bacterial laccases
(University of the Western Cape, 2015)The degradation of endocrine disrupting chemicals (EDCs) is a topic of high importance and one that research efforts are continually being focused on. These harmful chemicals are known to cause adverse health effects in ... -
Demitrios Tsafendas: race, madness and the archive
(University of the Western Cape, 2011)This thesis is concerned with the archival production on the life of Demitrios Tsafendas, the man who assassinated Hendrik Verwoerd on the 6 September 1966. Through an examination of three different archival registers: the ... -
Dendritic poly(3-hexylthiophene) star copolymer systems for next generation bulk heterojunction organic photovoltaic cells
(University of the Western Cape, 2018)The continuous increase in energy consumption and decrease in fossil fuels reserves are a primary concern worldwide; especially for South Africa. Therefore, there is an urgent need for alternative energy resources that ... -
Deposition and structural properties of silicon carbide thin films for solar cell applications.
(University of the Western Cape, 2014)The growth of hydrogenated amorphous silicon carbide (a-SiC:H) thin films deposited by Hot- Wire Chemical Vapour Deposition (HWCVD) for solar cell applications has been studied. The films were characterized for structural ... -
Deposition of silicon nanostructures by thermal chemical vapour deposition
(University of the Western Cape, 2015)In this thesis we report on the deposition of silicon nanostructures using a 3-zone thermal chemical vapour deposition process at atmospheric pressure. Nickel and gold thin films, deposited by DC sputtering on crystalline ... -
The depositional environment of Sandstone reservoirs, of wells within F-AH and F-AR field, offshore the Bredasdorp basin, South Africa
(University of the Western Cape, 2018)This study is located within the Bredasdorp Basin which is on the southern continental margin, offshore South Africa. The basin is located between Infanta and Agulhas arches and is a rift basin that is southeastern trending. ... -
Design and evaluation of fast dispersible tablets of lamivudine using selected natural superdisintegrants
(University of the Western Cape, 2018)Fast dispersible tablets (FDTs) are solid single-unit dosage forms that are placed in the mouth and allowed to disperse or dissolve in the saliva without the need of water. The basic approach to formulating FDTs consists ... -
The design and simulation of a new experimental set up to measure nuclear level lifetimes
(University of the Western Cape, 2016)Measurements of nuclear level lifetimes are an important aspect of experimental nuclear physics. Such measurements determine transition matrix elements for nuclear structure research and also provide the widths of relevant ... -
Design and synthesis of polycyclic amine derivatives for sigma receptor activity
(2013)New therapeutic strategies are needed for a diverse array of poorly understood neurological impairments. These include neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, and the psychiatric ... -
Design of a helium-6 production target for the iThemba LABS Radioactive-ion Beam Facility
(University of the Western Cape, 2018)It is well known, that there is a severe lack of information available pertaining to neutron rich nuclei, specifically of those nuclei with mass numbers ≥ 60. These neutron rich nuclei are not easy to access in current ... -
The design of ultrasensitive immunosensors based on a new multi-signal amplification gold nanoparticles-dotted 4-nitrophenylazo functionalised graphene sensing platform for the determination of deoxynivalenol
(University of Western Cape, 2014)A highly dispersive gold nanoparticle-dotted 4-nitrophenylazo functionalised graphene nanocomposite (AuNp/G/PhNO2) was successfully synthesised and applied in enhancing sensing platform signals. Three label-free ... -
Design, implementation and evaluation of a model for Service-learning in Pharmacy (SLIP) at a tertiary hospital
(University of the Western Cape, 2009)In recent years the focus of pharmacy practice has changed from being primarily 'drug-centred to' one which is 'patient-centred' (El-Awady et al., 2006, p. l ). Developments in pharmacy curricula worldwide are reflecting ... -
