Independent formant and pitch control applied to singing voice
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: A singing voice can be manipulated artificially by means of a digital computer for the
purposes of creating new melodies or to correct existing ones. When the fundamental frequency
of an audio signal ...
The development of a methodology to compile an insulator pollution severity application map for South Africa
(Stellenbosch : Stellenbosch University, 2005-04)
ENGLISH ABSTRACT: The main objective of this research project was to develop a methodology which can be
used to assist in developing an insulator pollution severity application map (INSMAP),
more particularly for South ...
Rotor design and performance evaluation of a PM-assisted reluctance synchronous traction machine
(Stellenbosch : Stellenbosch University, 2005-04)
ENGLISH ABSTRACT: The thesis describes the optimum rotor design and performance of a 110kW
Permanent-Magnet assisted (PM-assisted) Reluctance Synchronous traction Machine
(RSM) using bonded permanent magnet sheets. ...
Design of a Self Regulated and Protected Electrification Transformer
(Stellenbosch : University of Stellenbosch, 2007-03)
Electrification of rural areas is one of the biggest challenges faced by ESKOM and
methods are required to extend medium voltage distribution lines to these often
remote areas. As loads increase due to line-extension, ...
Design of a haptic controller for excavators
(Stellenbosch : University of Stellenbosch, 2009-03)
The input orientation of the excavators in use today usually comprises
two joysticks that control the actuator links individually. In order to perform
an excavation task, several different combinations of joystick ...
Autonomous docking for a satellite pair using monocular vision
(Stellenbosch : University of Stellenbosch, 2009-03)
Autonomous rendezvouz and docking is seen as an enabling technology. It allows, among
others, the construction of larger space platforms in-orbit and also provides a means for the
in-orbit servicing of space vehicles.
In ...
Active capacitor voltage stabilisation in a medium-voltage flying-capacitor multilevel active filter
(Stellenbosch : University of Stellenbosch, 2005-03)
A switching state substitution must be developed that will make use of both single-phase
redundancies and three-phase redundancies in the flying-capacitor topology. Losses should
be taken into consideration and the ...
Electricity theft detection on a low voltage reticulation environment
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: Electricity theft in South Africa has become a major problem. This led to several developments
from both industries and research institutes to counter these actions. Since equipment is already
installed ...
Path planning for an unmanned terrestrial vehicle in an obstacle ridden environment
(Stellenbosch : University of Stellenbosch, 2009-03)
This thesis relates to the successful development of an unmanned terrestrial
vehicle (UTV) capable of operating in an obstacle ridden environment. The
primary focus of the project is on the specific path planning algorithms. ...
Design and implementation of a DSP based controller for power electronic applications
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: In the field of power electronic engineering, there is a need for a reconfigurable power electronic
controller. Such a controller will enable engineers to stay focussed on their main field
of study, not ...
