The design of a communications strategy for an underwater sensor network
(Stellenbosch : Stellenbosch University, 2008-12)
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 ...
Benefits to processor load for quadrature baseband versus radio frequency demodulation algorithms
(Stellenbosch : Stellenbosch University, 2008-12)
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 ...
Cryogenic amplifiers for interfacing superconductive systems to room temperature electronics
(Stellenbosch : Stellenbosch University, 2008-12)
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 ...
Electronic voltage regulator technology for rural electrification
(Stellenbosch : Stellenbosch University, 2008-03)
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 ...
Design of a low power wireless sensor network for environmental monitoring
(Stellenbosch : Stellenbosch University, 2008-12)
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 ...
An infrared earth horizon sensor for a LEO satellite
(Stellenbosch : University of Stellenbosch, 2008-03)
Horizon sensing is an effective way to determine the pitch and roll of a LEO
satellite and Earth horizon sensors that operate in the visible range of the
electromagnetic spectrum are commonly used. These sensors have the ...

(Stellenbosch : Stellenbosch University, 2008-12)
This thesis presents the design of a control system for the autonomous
precision landing of an unmanned aerial vehicle aided by an infra red
camera for precision position measurements.
An optimal kinematics state estimator ...
An investigation into underwater navigation accuracy with regard to sensor combinations and quality
(Stellenbosch : Stellenbosch University, 2008-03)
A navigation performance sensitivity study with respect to the quality variation
of sensors and sensor combinations is presented in this thesis.
Navigation simulation software capable of using real-time and simulated
sensor ...
The design and analysis of a DC SQUID for a SQUID microscope
(Stellenbosch : Stellenbosch University, 2008-12)
This thesis relates to the analysis and design of a SQUID microscope. Superconductor theory is discussed
in depth to provide a thorough understanding of Josephson junctions and of dc SQUID magnetometers.
The behaviour ...
