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 ...
Abstract
Direct carbon fuel cell (DCFC) is a promising technology with high energy efficiency and abundant fuel. To date, a variety of DCFC configurations have been investigated, with molten hydroxide, molten ...
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 ...
Externally applied loads from high winds or impacts may cause structural damage to the
wind-turbine blade, and this may further affect the aerodynamic performance of the blade.
Wind-turbine blades experience high vibration ...
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 ...
The implications of comminution practices on the planning of a typical open pit mine was investigated in this study by means of computer simulation. The objective was to assess the effects of mining costs as well as ...
Supercapacitor is the best potential candidate of the energy storage system due to the
superior charge or discharge efficiency, high power density (>10 kW kg-1), and long cycling life. Porous carbon materials as the ...
The global community has accepted Fischer Tropsch synthesis as one of the sustainable pathways to transportation fuels and chemicals due to the ever-depleting reserves of fossil fuels and its detrimental impact on the ...
Cardiovascular diseases (CVD) remain one of the leading causes of deaths worldwide. The formation and
presence of aneurysm is a very important question in the study of this CVDs. An aneurysm is a balloon-like
bulge on a ...
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 ...
This study described an alternative approach for flotation circuit optimization using a mathematical programming technique. Mathematical formulation resulted in mixed integer nonlinear programming problem. Experimental ...
Abstract
This paper presents the findings of an investigation into the influence of green-synthesized nano-TiO2 on the characteristics of wood ash (WA) cement mortar. Mortar specimens were prepared by partial ...
This project provides a solution that alerts management if an Air Traffic Service Unit (ATSU) tower is unmanned during operational hours. The project makes provision for an access control with an automated on duty notification ...
In this paper, I report on the fabrication of micron-sized constrictions in YBCO thin films using the femtosecond laser technique.
The constrictions are S-shaped superconducting weak links fabricated on YBCO thin films. ...
The project arose as a result of the need to use the femtosecond laser to fabricate sub-micron and Nano-sized bridges that could be analyzed for the Josephson effect. The femtosecond laser has a low pulse duration of 130 ...
