(University of the Western Cape, 2019)Air pollution is becoming a challenging issue in our daily lives due to advanced industrialization. This thesis presents a solution to collection and dissemination of pollution data. Most of the devices that monitor air ... -
Smart renewable energy : architectures, dimensioning and monitoring
(University of the Western Cape, 2017)The Smart Renewable Energy project at the University of The Western Cape, under the guidance of the Intelligent Systems and Advanced Telecommunication (ISAT) group, aims at developing a dynamic system that enables users ... -
Social and technical issues of IP-based multi-modal semi-synchronous communication: rural telehealth communication in South Africa
(University of the Western Cape, 2005)Most rural areas of developing countries are faced with problems like shortage of doctors in hospitals, illiteracy and poor power supply. Because of these issues, Information and Communication Technology (ICT) is often ... -
South African Sign Language Hand Shape and Orientation Recognition on Mobile Devices Using Deep Learning
(University of the Western Cape, 2017)In order to classify South African Sign Language as a signed gesture, five fundamental parameters need to be considered. These five parameters to be considered are: hand shape, hand orientation, hand motion, hand location ... -
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 constuct a feature vector, dynamic ... -

Static MySQL Error Checking
(University of the Western Cape, 2010)Coders of databases repeatedly face the problem of checking their Structured Query Language (SQL) code. Instructors face the difficulty of checking student projects and lab assignments in database courses. We collect and ... -
The strategic role of software development within the software industry of the Western Cape (South Africa)
(University of the Western Cape, 2016)Africa’s mobile phone penetration has surpassed that of the United States of America and information communication technologies, according to the World Bank, contribute more to its gross domestic product than the global ... -
Synergistic use of promoter prediction algorithms: A choice for small training dataset?
(University of the Western Cape, 2000)This chapter outlines basic gene structure and how gene structure is related to promoter structure in both prokaryotes and eukaryotes and their transcription machinery. An in-depth discussion is given on variations types ... -
Synergistic use of promoter prediction algorithms: a choice of small training dataset?
(University of the Western Cape, 2000)Promoter detection, especially in prokaryotes, has always been an uphill task and may remain so, because of the many varieties of sigma factors employed by various organisms in transcription. The situation is made more ... -
A technique for the evaluation of free and open source e-learning systems
(University of the Western Cape, 2010)Evaluating software is a universal and complex problem. The question is: how should software be selected and adopted, or rather, which of the software packages is the most suitable for a specific environment? Extensive ... -
Toward Authentication Mechanisms for Wi-Fi Mesh Networks
(University of the Western Cape, 2011)Wi-Fi authentication mechanisms include central authentication, dynamic and distributed authentication and some encryption methods. Most of the existing authentication methods were designed for single-hop networks, as ... -
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 ... -
Towards a unified modelling framework for adaptive networks.
(University of the Western Cape, 2014)Adaptive networks are complex networks with nontrivial topological features and connection patterns between their elements which are neither purely regular nor purely random. Their applications are in sociology, biology, ... -
Towards ensuring scalability, interoperability and efficient access control in a triple-domain grid-based environment
(2012)The high rate of grid computing adoption, both in academe and industry, has posed challenges regarding efficient access control, interoperability and scalability. Although several methods have been proposed to address ... -
