A load management system for fixed appliances in a safe DC RDP house
(Cape Peninsula University of Technology, 2017)This dissertation represents the design and development of a load management system for fixed appliances in a safe direct current (DC) Reconstruction and Development Programme (RDP) house. A combination of valley filling, ... -
Mission design of a CubeSat constellation for in-situ monitoring applications
(Cape Peninsula University of Technology, 2017)Real-time remote monitoring of Africa’s resources, such as water quality, by using terrestrial sensors is impeded by the limited connectivity over the vast rural areas of the continent. Without such monitoring, the effective ... -
Numerical study of non-linear spectroscopy and four-wave-mixing in two and multi-level atoms
(Cape Peninsula University of Technology, 2017)In this research, we undertake a numerical study of the interaction between laser beams and two as well as multi-level atoms. The main aim of this research is to obtain a deeper understanding of laser-atom interactions ... -
Saturated absorption spectroscopy of rubidium and feedback control of LASER frequency for Doppler cooling
(Cape Peninsula University of Technology, 2018)This research investigates the absorption spectra of rubidium and the feedback control of an external cavity diode laser. This research is a necessary prerequisite for laser (Doppler) cooling and trapping of rubidium ... -
Reconfigurable photovoltaic modules for robust nanosatellite power systems
(Cape Peninsula University of Technology, 2018)Until recently, the focus of most solar technology development for space was towards more efficient, more radiation-resistant and increasingly powerful arrays. During a space mission, solar cells are not only exposed to ... -
Development of methods for modelling, parameter and state estimation for nonlinear processes
(Cape Peninsula University of Technology, 2017)Industrial processes tend to have very complex mathematical models that in most instances result in very model specific optimal estimation and designs of control strategies. Such models have many composition components, ... -
Investigation of process parameters and development of a mathematical model for the purposes of control design and implementation for a wastewater treatment process
(Cape Peninsula University of Technology, 2009)The problem for effective and optimal control of wastewater treatment plants is very important recently because of the increased requirements to the quality of the effluent. The activated sludge process is a type of ... -
Investigation of 3 terminal differential protection using standard-based numerical relays
(Cape Peninsula University of Technology, 2017)Transmission lines are a vital part of the electrical distribution system, as they provide the path to transfer power between generation and load. Factors like de-regulated market environment, economics, etc. have pushed ... -
Implementation of a reverberation chamber for electro-magnetic compatibility measurements
(Cape Peninsula University of Technology, 2017)This research project focuses on the implementation of a Reverberation Chamber (RC) by the transformation of an existing electromagnetically shielded room. The reverberation chamber is a kind of shielded room designed to ... -
Optimisation of doping profiles for mm-wave GaAs and GaN gunn diodes
(Cape Peninsula University of Technology, 2017)Gunn diodes play a prominent role in the development of low-cost and reliable solid-state oscillators for diverse applications, such as in the military, security, automotive and consumer electronics industries. The primary ... -
Condition monitoring of squirrel cage induction generators in wind turbines
(Cape Peninsula University of Technology, 2017)Globally governments are faced with challenges in the energy sector which are exacerbated by uncertain financial markets and resource limitations. The over utilization of fossil fuels for electricity generation has had a ... -
Thermal electric solar power conversion panel development
(Cape Peninsula University of Technology, 2017)The world has been experiencing energy-related problems following pressuring energy demands which go along with the global economy growth. These problems can be phrased in three paradoxical statements: Firstly, in spite ... -
Design and development of a fuel cell power supply unit
(Cape Peninsula University of Technology, 2017)Fuel cell (FC) technology is one of the most sought-after renewable energy technology. However, the output voltage of FC stacks is inherently unstable; as such, it is of little or no use for most power supply applications. ... -
Design and operation of a stand-alone solar pathway for public park lighting
(Cape Peninsula University of Technology, 2017)The development of solar roads to convert insolation on vast stretches of land to electrical energy, otherwise dedicated solely for transportation, is in its nascent stage. A great potential is seen for PV application ... -
Mitigating interference from switch-mode power supplies in sampling receivers
