-
(University of Pretoria, 2022)Microgrids are gaining popularity due to their ability to integrate distributed renewable energy generation. In addition, direct current (DC) - based operation results in significantly higher operational efficiency. However, ...
-
(University of Pretoria, 2022)The addition of a short-term energy-storage system in conjunction with the battery to reduce fuel consumption, reduce emissions, and increase the service life of the battery is considered. A quasi-static simulation approach ...
-
(University of Pretoria, 2023)Detailed steady and transient state models of vapor compression (VC) systems have been suggested in this work so that the governing parameters of the refrigerant dynamics such as pressure, enthalpy and temperature could ...
-
(University of Pretoria, 2022)The development of wireless technologies such as the Long Range Wide Area Network (LoRaWAN) protocol has enabled connectivity for a wide range of devices for optimisation and automation purposes. These types of technologies ...
-
(University of Pretoria, 2023)Over the past few decades radar cross section (RCS) manipulation has become increasingly important. This increase in interest is due to the development and improvement of stealth technology. While many RCS manipulation ...
-
(University of Pretoria, 2022)Virtual Reality (VR) allows the visualisation and exploration of detailed 3D environments. Recent advances in technology have made the use of VR more accessible for research and industry applications. VR is especially ...
-
(University of Pretoria, 2022)In several quadcopter-related research work, the research mainly focuses on the image processing application and generally provides an inadequate description of the navigation and control of the quadcopter. While image ...
-
(University of Pretoria, 2020)In the recent years there has been a great deal of attention on the optimal demand and supply side strategy. The increase in renewable energy sources and the expansion in demand response programmes has shown the need for ...
-
(University of Pretoria, 2022)This study investigates the implementation of a controller strategy to emulate flare trajectories on a Hardware-in-the-loop Simulation (HILS) platform. Flares are employed as countermeasures in aerial defence systems and ...
-
(University of Pretoria, 2022)Complex systems are in place for the localization and tracking of High Speed Trains. These methods tend to perform poorly under certain conditions. Localization using 5G infrastructure has been considered as an alternative ...
-
(University of Pretoria, 2022)Power system restoration after a blackout incident requires an integrated effort between the generation, transmission and distribution utilities. Restoration planning of the South African interconnected power system (SA ...
-
(University of Pretoria, 2021)Conventional receivers for high-frequency (HF) waveforms using phase-shift keying (PSK) or quadrature amplitude modulation (QAM) symbol mapping contain an equaliser to equalise channel effects and a forward error correction ...
-
(University of Pretoria, 2015)Solar-blind Ultraviolet cameras are used to detect missile plumes and perform the detection of corona on high voltage electrical lines. This study investigates the influence of the spectral transfer function of a specific ...
-
(University of Pretoria, 2021)Advanced driver-assistance systems (ADAS) are more prevalent in high-end vehicles than in low-end vehicles. The research proposes an alternative for drivers without having to wait years to gain access to the safety ADAS ...
-
(University of Pretoria, 2021)Cell differentiation is a fundamental process in biology by which cells progress through different stages of maturation to become specialised cell types. Owing to the importance of understanding the process of cell ...
-
(University of Pretoria, 2021)Underrating of underground cables could result in the drying out of the soil around the cable. This results in inferior cable performance and has potential negative environmental impacts. IEC 60287 is used for cable ...
-
(University of Pretoria, 2021)Motion segmentation is part of the computer vision field and aims to find the moving parts in a video sequence. It is used in applications such as autonomous driving, surveillance, robotics, human motion analysis, and video ...
-
(University of Pretoria, 2020)System specifications and testing model for increasing the rated power output, rotor diameter, hub height, and maximum tip speed of horizontal axis wind turbines is designed and implemented on the system advisor model ...
-
(University of Pretoria, 2021)Medium voltage feeders are evolving from traditional radial topologies to interconnected feeders with distributed generation. For a feeder with a source at either end, the circuit breakers at both ends have to open to ...
-
(University of Pretoria, 2020)This dissertation studied the problem of face recognition when facial images have partial occlusions like sunglasses and scarfs. These partial occlusions lead to the loss of discriminatory information when trying to recognise ...
