Electrical energy storage is very important. Energy storage devices such as batteries and capacitors can be used to store energy. In this dissertation we investigate the use of a supercapacitor or electric double-layer ...
Data acquisition system for pilot mill

Molepo, Isaih Kgabe (2016-04)

This dissertation describes the development, design, implementation and evaluation of a data acquisition system, with the main aim of using it for data collection on a laboratory pilot ball mill. An open-source prototype ...
Data mining and predictive analytics application on cellular networks to monitor and optimize quality of service and customer experience

Muwawa, Jean Nestor Dahj (2018-11)

This research study focuses on the application models of Data Mining and Machine Learning covering cellular network traffic, in the objective to arm Mobile Network Operators with full view of performance branches (Services, ...
Detection and identification of faulty modules in a large-scale photovoltaic installation

Yokwana, Xolani Phillip (2020-01)

The global warming and realisation that fossil fuel is limited, has been a drive over the years to move to renewable energy sources (RES). Consequently, solar energy and other renewable energy sources are currently being ...
Detection of pulmonary tuberculosis using deep learning convolutional neural networks

Norval, Michael John (2019-11)

If Pulmonary Tuberculosis (PTB) is detected early in a patient, the greater the chances of treating and curing the disease. Early detection of PTB could result in an overall lower mortality rate. Detection of PTB is ...
Development of neural network-based speech/non-speech discrimination algorithm for audio files

Redelinghuys, Herman (2022-01)

For research in speech processing and analysis of audio content in general, extensive data sets are required. Creating such a dataset manually turns out to be time and labour consuming, but it is a task very suitable ...
Driver attention and behaviour monitoring with the Microsoft Kinect sensor

Solomon, Cleshain Theodore (2015-11)

Modern vehicles are designed to protect occupants in the event of a crash with some vehicles better at this than others. However, passenger protection during an accident has shown to be not enough in many high impact ...
Evaluating of DNP3 protocol over serial eastern operating unit substations and improving SCADA performance

Njova, Dion (2021-07-14)

Supervisory Control and Data Acquisition (SCADA) is a critical part of monitoring and controlling of the electrical substation. The aim of this dissertation is to investigate the performance of the Distributed Network ...
