Automatic signature verification system
(2013)In this thesis, we explore dynamic signature verification systems. Unlike other signature models, we use genuine signatures in this project as they are more appropriate in real world applications. Signature verification ... -
Automorphism groups of some designs of steiner triple systems and the atomorphism groups of their block intersection graphs
(University of the Western Cape, 2014)A Steiner triple system of order v is a collection of subsets of size three from a set of v-elements such that every pair of the elements of the set is contained in exactly one 3-subset. In this study, we discuss some ... -
Autonomous facial expression recognition using the facial action coding system
(University of the Western Cape, 2016)The South African Sign Language research group at the University of the Western Cape is in the process of creating a fully-edged machine translation system to automatically translate between South African Sign Language and ... -
The availability of persons nominated for adverse drug reporting and associated challenges in Gauteng regional and district public hospitals
(University of the Western Cape, 2019)Background and Objectives: The reporting of adverse drug reactions (ADRs) is a major public health necessity. It is estimated that only six to 10 percent of all ADRs are reported worldwide. This number is far less than the ... -
The availability, applicability and utility of information systems engineering standards in South African higher education
(University of the Western Cape, 2016)Higher education institutions in South Africa have invested heavily in information technology and information systems, with variable outcomes. Organisations in other sectors, such as engineering, the defence industry, ... -
Avatar animation from SignWriting notation
(University of the Western Cape, 2015)The SASL project at the University of the Western Cape is in the process of developing a machine translation system that can translate fully-fledged phrases between South African Sign Language (SASL) and English in ... -
Awareness regarding non-steroidal anti-inflammatory drug-related side effects in Johannesburg, South Africa
(University of Western Cape, 2021)Non-steroidal anti-inflammatory drugs (NSAIDs) are amongst the most commonly used medications globally, as they are highly effective and easily accessible. The NSAIDs are indicated for mild to moderate pain management. The ... -
Bacillus licheniformis isolated from Mozambican soil capable of producing 2, 3-butanediol
(The University of the Western Cpae, 2018)Due to the current fossil fuel sources rapidly depleting as a result of the increased global need, alternative, sustainable and renewable sources are required. Biofuels, which are environmentally friendly, meet all the ... -
Bacteriophage diversity in haloalkaline environments
(University of the Western Cape, 2013)There are limited reports on virus population in haloalkaline environments; therefore the aim of this study was to investigate the genetic diversity and biology of bacteriophage communities in these environments. Bacteria ... -
Baobab LIMS: An open source biobank laboratory information management system for resource-limited settings
(University of the Western Cape, 2019)A laboratory information management system (LIMS) is central to the informatics infrastructure that underlies biobanking activities. To date, a wide range of commercial and open source LIMS are available. The decision ... -
Barley anther culture: determining the optimal pre-treatment for green plant regeneration
(2013)Doubled Haploid (DH) Technology is an important tool for plant breeding and biotechnological applications as it accelerates the breeding cycle of plants by shortening the time required to attain homozygosity. Anther culture ... -
A baseline evaluation of the cytotoxicity of gold nanoparticles in different types of mammalian cells for future radiosensitization studies
(University of the Western Cape, 2020)Recently nanoparticles (NPs) have been introduced and used in combination with therapeutic approaches to develop nanotechnology-enabled medicine. These nanostructures allow for the exploitation of the physiochemical ... -

Basin Evaluation of Turonian Deposits in the Lower Congo Basin using outcrops, cores, well-logs and seismic
(University of the Western Cape, 2017)This manuscript presents a review of the Turonian series of the Congolese Coastal Basin using outcrop, core, well-logs and seismic data in order to provide a comprehensive model for the series and increase the oil recovery. ... -
The behaviour and feeding ecology of extralimital giraffe within Albany Thicket vegetation in the Little Karoo, South Africa
(University of the Western Cape, 2018)Due to their popularity for tourism, giraffes are being introduced into Thicket areas within the Little Karoo region of the Western Cape. However, information regarding the activity budgets and diet selection of these ... -
Being a mother and owning an informal hairdressing business in Cape Town, South Africa : a study on Congolese female migrants
(University of the Western Cape, 2015)This study investigates how female migrants negotiate the tension that arises from being entrepreneurs, being mothers, and having families. It shows how entrepreneurship offers them self-emancipation but limits the time ... -
Bioactive actinobacteria associated with two South African medicinal plants, Aloe ferox and Sutherlandia frutescens
(University of Western Cape, 2021)Actinobacteria, a Gram-positive phylum of bacteria found in both terrestrial and aquatic environments, are well-known producers of antibiotics and other bioactive compounds. The isolation of actinobacteria from unique ... -
Bioactivity and genome guided isolation of a novel antimicrobial protein from Thalassomonas viridans
(University of the Western Cape, 2019)The continued emergence of bacterial resistance to the antibiotics currently employed to treat several diseases has added to the urgency to discover and develop novel antibiotics. It is well established that natural products ... -
Bioactivity guided fractionation of Sutherlandia frutescens extracts for the induction of apoptosis
