A T-resonator technique for aperture plane admittance parameters of electrically short RF monopoles
(Stellenbosch : University of Stellenbosch, 2006-12)
This thesis focuses on the coaxial-microstrip T-resonator measurement technique to
determine the aperture plane capacitance and radiation resistance of electrically short
monopoles above a finite ground plane at Radio ...
An investigation of satellite maneuvering and orientation strategies using an air bearing table
(Stellenbosch : University of Stellenbosch, 2005-12)
In this thesis, the maneuvering and orientation of an inspection/service satellite is investigated.
This thesis will demonstrate a simplified satellite maneuver around another
satellite (for docking purposes). This is ...
Attitude determination and control system of a nanosatellite
(Stellenbosch : University of Stellenbosch, 2007-12)
The aim of this project was to design and test a partial attitude determination
and control system for a nanosatellite. The reaction wheel system was
designed and tested as an actuator for the nanosatellite. This reaction ...
An investigation into the phase noise of quartz crystal oscillators
(Stellenbosch : University of Stellenbosch, 2007-03)
As secondary objective an introduction to the quantification, theory and measurement of phase noise is presented to make this field of study more accessible for the novice to the field. Available phase noise theory is ...
Tree-based Gaussian mixture models for speaker verification
(Stellenbosch : University of Stellenbosch, 2005-12)
The Gaussian mixture model (GMM) performs very effectively in applications
such as speech and speaker recognition. However, evaluation speed is greatly
reduced when the GMM has a large number of mixture components. ...
The design and testing of a superconducting programmable gate array
(Stellenbosch : University of Stellenbosch, 2006-03)
This thesis investigates to the design, analysis and testing of a Superconducting Programmable
Gate Array (SPGA). The objective was to apply existing programmable logic concepts to
RSFQ circuits and in the process develop ...
