Machine learning (ML) in healthcare is crucial for establishing and enhancing performant automated disease detection systems that can be used in medical practice. This dissertation aims to improve ML classifiers for disease ...
Machine Learning (ML) or Artificial Intelligence (AI) approaches in a distribution protection system are proposed to detect and categorize distribution network (DN) issues with Distribution Generation. This study highlights ...
The objective of the thesis was two-fold: to investigate the potential of implicit modelling techniques for modelling geometallurgical parameters in mine planning and to generate synthetic geometallurgical data using ...
In this article a series of constrictions in the micron and sub-micron range
fabricated with the femtosecond laser on superconducting YBa2Cu3O7 thin
films is scanned with an atomic force microscope (AFM). The AFM images ...
Minerals should be sufficient to sustain security of the nation as well as
growth of the economy and employment. Countries without minerals may
source minerals from mineral-rich countries. South Africa is endowed with ...

Cryptographic attacks on Internet of Things (IoT) devices are not highly con sidered by the users of IoT. Most cryptographic algorithms commonly used on
IoT devices are vulnerable to cryptographic attacks. Cryptography ...
The use of crushed basalt aggregates as an alternative to sand aggregates
is gaining momentum. This is driven by efforts of ensuring sustainable
developments in shotcrete production. The main objective of this study ...
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 ...
This paper investigates the effect of the electric double layer capacitor (EDLC) in reducing
stress and prolonging the battery lifespan in a hybrid energy storage system (HESS). A 65 F, 16.2 V
EDLC supercapacitor was ...

The idea of a mid-term energy storage system (ESS) is becoming a popular option for
improving the performance of energy conservation, power efficiency and the power grid.
The goal of this research is to explore the ...
The South African power utility, Eskom, and, in turn, the metropolitan and local
municipalities, have difficulty meeting the country's growing demand for electricity. In this
study, electric water heaters have been ...
This paper investigates the characterization of an electric double-layer capacitor (EDLC). In this study, the 300 F and 400 F EDLC supercapacitors are connected in a circuit in a laboratory experiment to produce their ...
