Developing a generic request-processor for systems with limited request processing resources
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: This thesis describes the design, modelling and implementation of a prototype request-
processing software system, which can be used as the basis for a request processing frame-
work for systems with ...
The design of a high-performance, floating-point embedded system for speech recognition and audio research purposes
(Stellenbosch : Stellenbosch University, 2008-03)
This thesis describes the design of a high performance, floating-point, standalone embedded
system that is appropriate for speech and audio processing purposes.
The system successfully employs the Analog Devices TigerSHARC ...
Metrology and modelling of high frequency probes
(Stellenbosch : Stellenbosch University, 2008-03)
This study investigates high frequency probes through good metrology and
computation software such as CST. A factor that can strongly influence the accuracy
of measurements, is common mode (CM) current. Therefore, the ...
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 ...
Development of a low phase noise microwave voltage controlled oscillator
(Stellenbosch : Stellenbosch University, 2008-12)
The topic for this project entailed the development of a ‘Low Phase Noise –
Microwave – Voltage Controlled Oscillator’ for use in radar applications.
First of all, a low phase noise oscillator was designed. In order to ...
Autonomous flight of an unmanned helicopter
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: The successful development of an autopilot for an unmanned helicopter is
presented. The helicopter model is developed from first principles. The
model is decoupled to enable the design of four separate ...
Autonomous navigation using ad-hoc networking
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: A solution for autonomous navigation is described and demonstrated using simulations.
The novelty is to use a set of interconnecting nodes with self-locating properties for
navigation. This work defines ...
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 ...
