This project investigates two problems related to satellites that contain cold gas thrusters and reaction wheels. The first problem concerns the estimation of the thruster force response to a pulse command. An optimal data ...

In an ideal software defined radio (SDR), all parameters are defined in software, which means the radio can be reconfigured to handle any communications standard. A major technical challenge that needs to be overcome ...

The aim of the thesis is to design a Control Moment Gyro (CMG) actuator which can be used in small satellite applications. The hardware and software of the CMG has to be designed according to specifications given. A ...

The open-ended coaxial probe is revisited as a broadband measurement system for general high frequency permittivity measurements. Three coaxial probes were developed that are suited for the measurement of both liquids ...

This thesis is about the dynamic control of a permanent magnet assisted reluctance synchronous machine (PMA RSM). The PMA RSM in this thesis is a 110 kW traction machine and is ideal for the use in electrical rail vehicles. ...

This thesis covers the design and development of a radio telemetry system to assist in management of the Grumeti reserves. This was accomplished through the integration of a digital data transmission system into the ...

The African Speech Technology (AST) project ran from 2000 to 2004 and involved collecting speech data for five South African languages, transcribing the data and building automatic speech recognition systems in these ...

There is currently a disparity in the amount of research done in underwater communication when compared to terrestrial communication. Therefore, it was the goal of this work to try and make an initial step towards bridging ...

The continued advancement and improvement of software-defined radio technology has been a key factor in furthering research into the implementation of most signal processing algorithms at baseband. Traditionally, these ...

The purpose of this study was to investigate multi-spectral tracking. Various algorithms were investigated and developed to enhance the contrast between target and non-target classes. Different tracking algorithms were ...
