A major challenge in the design and operation of High Temperature Superconducting (HTS) devices is the fabrication of reproducible Josephson junctions with good IcRn products. One objective of this thesis was to fabricate ...

This thesis relates to the design of a camera system for a nanosatellite based on a CMOS image sensor. The design specifications and constraints are considered followed by the proposal of a versatile design with all the ...

Integrated circuits are expensive to manufacture and it is important to verify the correct operation of a circuit before fabrication. Efficient, though accurate, parameter extraction of post-layout designs are required ...

SumbandilaSat is the second South African satellite, and is scheduled to be launched in April/May 2007. A software defined radio (SDR) automatic identification system (AIS) receiver is proposed as a possible experimental ...

This thesis is aimed at testing commercially available CMOS amplifier ICs at 4 K. Super Conducting Electronics (SCE) will also be used to amplify RSFQ signals for easier detection by CMOS technology and better ...

ENGLISH ABSTRACT: This thesis discusses the development of a 5 kVA single phase AC voltage regulator, specifically designed to assist in the reduction of electrification costs in sparsely populated rural areas. The voltage ...

An analysis of the attitude determination and control system required for a small geostationary satellite is performed in this thesis. A three axis quaternion feedback reaction wheel control system is the primary control ...

A WSN (wireless sensor network) consists of a collection of small, low power electronic devices that can sense their environment and communicate with each other in order to send data to a base station for logging and ...

The use of ground penetrating radar, and especially borehole radar in underground mines, is becoming increasingly attractive. This is due to the improvements in the user friendliness of this system. Borehole radar is ...

Ground penetrating radar is currently proving itself as an invaluable tool for the prediction of geological structures in the mining environment. Borehole radar is a specific application of this technology, useful in the ...
