Semantic data access for relational databases using an ontology
(University of the Western Cape, 2024)Data analysis-based decision-making is performed daily by domain experts. As data grows in size and heterogeneity, accessing relevant data becomes challenging. In an Ontology-based data access (OBDA) approach, ontologies ... -
On the efficacy of enhanced feature selection methods for supervised crime prediction
(University of the Western Cape, 2023)The challenge of crime across the globe has necessitated several considerations for crime preventive measures. There exist a variety of crime prevention strategies, such as the use of necessary weapons or tools to respond ... -
Exploring low-cost solution for 3D crime scene data gathering with immersive technology
(University of the Western Cape, 2023)3D crime scene data gathering is critical for law enforcement and investigators during crime scene investigations. Crime scene investigations have seen the effective usage of Light Detection and Ranging (LiDAR) scanners ... -
Application of Several Time Series Methods to Three Important Financial Time Series
(University of the Western Cape, 2007)This study is concerned with three different financial time series over an eight year period, namely: the government repurchase rate, the Rand-Dollar exchange rate and the Allshare Index. The aim is to better understand ... -
Semi-synchronous video for deaf telephony with an adapted synchronous codec
(University of the Western Cape, 2009)As Information and Communication Technology (ICT) matures, communication services must be improved to meet the needs of all types of users. For some uses, current Video over Internet Protocol (IP) brings unsatisfactory ... -
Long short-term memory recurrent neural networks for signature verification
(UWC, 2003)Handwritten signature verification is defined as the classification process that strives to learn the manner in which an individual makes use of the muscular memory of their hands, fingers, and wrist to reproduce a signature. ... -
Towards a chereme based dynamic South African sign language gesture recognition system
(University of the Western Cape, 2007)Hand gestures are a natural and intuitive way of human to human communication. Motivated by the achievements made towards automatic speech recognition, and by the ease with which people sign, many researchers started ... -
Automatic real-time facial expression recognition for signed language translation
(University of the Western Cape, 2006)We investigated two computer vision techniques designed to increase both the recognition accuracy and computational efficiency of automatic facial expression recognition. In particular, we compared a local segmentation of ... -
Handwritten alphabet character recognition using audio signatures and machine learning
(University of the Western Cape, 2023)This research investigates the creation of an audio-based character recognition system that is able to segment, process and recognise uppercase English letters continuously drawn by the user on a given writing surface ... -
A comparative evaluation of population-based optimization algorithms for workflow scheduling in cloud-fog environments
(University of the Western Cape, 2022)Scientific workflows are denoted by interdependent tasks and computations that are aimed at achieving some scientific objectives. The scheduling of these workflows involve the allocation of the tasks to particular ... -
Credit Card Transactions Fraud Detection, and Machine Learning: Modelling Time with LSTM Recurrent Neural Networks
(University of the Western Cape, 2007)In recent years, topics such as fraud detection and fraud prevention have received a lot of attention on the research front, in particular from plastic card issuers. The reason for this increase in research activity can ... -
Geo-physical parameter forecasting on imagery{based data sets using machine learning techniques
(University of Western Cape, 2021)This research objectively investigates the e ectiveness of machine learning (ML) tools towards predicting several geo-physical parameters. This is based on a large number of studies that have reported high levels of ... -
KernTune: Self-tuning Linux Kernel Performance Using Support Vector Machines
(University of the Western Cape, 2006)Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ... -
The Efficacy of the Eigenvector Approach to South African Sign Language Identification
(University of the Western Cape, 2010)The communication barriers between deaf and hearing society mean that interaction between these communities is kept to a minimum. The South African Sign Language research group, Integration of Signed and Verbal Communication: ... -
A comparative evaluation of 3d and spatio-temporal deep learning techniques for crime classification and prediction
(University of Western Cape, 2021)This research is on a comparative evaluation of 3D and spatio-temporal deep learning methods for crime classification and prediction using the Chicago crime dataset, which has 7.29 million records, collected from 2001 ... -
Chereme- Based Recognition of Isolated, Dynamic Gestures from South African Sign Language with Hidden Markov Models
(University of the Western Cape, 2006)Much work has been done in building systems that can recognise gestures, e.g. as a component of sign language recognition systems. These systems typically use whole gestures as the smallest unit for recognition. Although ... -
A Digital Identity Management System
(University of the Western Cape, 2007)The recent years have seen an increase in the number of users accessing online services using communication devices such as computers, mobile phones and cards based credentials such as credit cards. This has prompted most ... -
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 ... -
Security related self-protected networks: Autonomous threat detection and response (ATDR)
(University of Western Cape, 2021)Cybersecurity defense tools, techniques and methodologies are constantly faced with increasing challenges including the evolution of highly intelligent and powerful new-generation threats. The main challenges posed by ... -
Self-tuning Linux Kernel Performance Using Support Vector Machines
(University of the Western Cape, 2006)In this chapter, we provide the motivation and background behind the automatic optimisation of an operating system. We begin with a discussion of some of the difficulties of automatic operating system optimisation and ...
