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 ...
Over the past fifty years Valve Regulated Lead Acid (VRLA) battery has been deployed with Uninterruptable Power Supplies (UPS) backup systems as a last line of defense against primary power outages, due to its affordability ...
The worldwide utilisation of renewable energy in electric power systems is growing rapidly due to concerns about the environment and the depletion of the sources of conventional power generation. The Weibull distribution ...
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 ...
There exists a need to understand the behaviour of wet mill loads by numerical simulation. However, the challenge is to adequately combine solid-based and liquid-based computer algorithms into one realistic framework. This ...
The production of low-carbon energy products from biomass gasification is encouraged,
in order to expand our sources of energy and to mitigate the harmful impact of the pollutants on the climate and the environment. The ...
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 ...
The recent advances of e-commerce and e-payment systems have sparked an increase in financial fraud cases such as credit card fraud. It is therefore crucial to implement mechanisms that can detect the credit card fraud. ...
Maize (zea mays) is the staple food of Southern Africa and most of the African regions. This staple food has
been threatened by a lot of diseases in terms of its yield and existence. Within this domain, it is important ...
In this paper, we demonstrate the fabrication of S-shaped micron-sized constrictions on steel (Fe3CII) surface using the femtosecond
laser ablation technique. The femtosecond laser used has a wavelength of 775 nm, a power ...
In the field of computer vision, multi-class outdoor weather classification is a difficult task to
perform due to diversity and lack of distinct weather characteristic or features. This research
proposed a novel framework ...
We live in a world with ever-increasing digital technology, hence the need for enhanced security systems is vital. In the past a simple PIN or password would have been sufficient to maintain the integrity of security ...
This system monitors and controls the temperature in a marine aquarium. This system measures the water temperature in an aquarium and then uses a heater and cooling fan to control the temperature within a range of 25-27°C. ...
Small-scale wind turbines were not considered viable in the past due to their poor
efficiencies, mainly because of their aerodynamic effects around the irfoil shape. Recently
researchers have renewed interest in enhancing ...
The PID controller is regarded as a dependable and reliable controller for process industry systems. Many researchers have devoted time and attention to PID controller tuning and they all agree that PID controllers are ...
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 ...
The work title ‘Use of Recovery-by-Size Data from Batch Testing in Estimating the
Performance of Continuous Flotation Operations’ seeks to validate available
theories against recovery-by-size batch flotation data and ...
Facial expression recognition (FER) is still a challenging concept, and machines struggle to
comprehend effectively the dynamic shifts in facial expressions of human emotions. The
existing systems, which have proven to ...
The objective of this thesis was to identify the mechanisms associated with the recurrence of rock-slope instability along the R518 and R523 roads in Limpopo. Advanced geotechnical methods and ASTER imagery were used for ...
