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 for health-care: Patient condition recognition
(University of the Western Cape, 2019)The emergence of the Internet of Things (IoT) and Artificial Intelligence (AI) have elicited increased interest in many areas of our daily lives. These include health, agriculture, aviation, manufacturing, cities management ... -
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 ... -
Deciphering the determinants of molecular physiological responses to drought and heat stress in sorghum lines contrasting in stress tolerance via a proteomics approach
(University of the Western Cape, 2022)Sorghum is an important crop in Sub-Saharan Africa and South Asia. The predicted rise in global temperatures will increase the probability of exposing sorghum to heat waves in combination with drought. Thus, production ... -
A decision-making framework for groundwater management in arid zones (with a case study in Namaqualand).
(University of the Western Cape, 2004)The main aim of the work on which this thesis is based was to develop a framework for sustainable management of groundwater resources in arid zones with emphasis on Namaqualand in the north western region of South Africa. ... -
A deep learning approach to predicting potential virus species crossover using convolutional neural networks and viral protein sequence patterns
(University of the Western Cape, 2022)Medical science has made substantial progress toward diagnosing, understanding the pathogenesis, and treating various causative agents of infectious disease; however, novel microbial pathogens continue to emerge, and ... -
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 ... -
