Mathematical and numerical analysis of electrospraying electrodynamics
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: The electrodynamics of arbitrary, point-to-plane electrospraying geometries,
were investigated in this research both analytically and numerically. Electrospraying
is the process during which particles ...
Optimal estimation and sensor selection for autonomous landing of a helicopter on a ship deck
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: This thesis presents a complete state estimation framework for landing an unmanned
helicopter on a ship deck. In order to design and simulate an optimal state estimator,
realistic sensor models are ...
Time domain metrology for MeerKAT systems
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: This work in this study covers a powerful technique to derive propagation and scattering information
in an expedient fashion. Expedient because time-domain (TD) data gathers a broad spectrum
in a single ...
Intelligent elevator control based on adaptive learning and optimisation
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: Machine learning techniques have been around for a few decades now and
are being established as a pre-dominant feature in most control applications.
Elevators create a unique control application where ...
A 3-axis attitude control system hardware design for a CubeSat
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: With CubeSats becoming popular as a cheap alternative to larger satellites, the need
for advanced miniature attitude determination and control systems (ADCS) arises to
meet the pointing requirements of ...
Development of a satellite network simulator tool and simulation of AX.25, FX.25 and a hybrid protocol for nano-satellite communications
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: Nano-satellites are mostly used in lower earth orbit applications, where communication
intervals are limited, often to a combined total of less than one hour per day. With these type
of inherent limitations ...
Design and development of a satellite ground station for water resource monitoring
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: The SU Department of Forestry has the responsibility to monitor, assess and suggest
management processes for water resources in some remote areas. The researchers need
information on wind speed, wind ...
The design and implementation of a prototype digital video watermarking scheme with dynamic traitor tracing
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: We design and implement a prototype digital watermarking scheme that uses
spread-transform dither modulation to embed hidden binary message signals
into uncompressed digital video signals. The hidden ...
Design and implementation of generic flight software for a CubeSat
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: The main on-board computer in a satellite is responsible for ensuring the correct
operation of the entire system. It performs this task using flight software. In order to
reduce future development costs, ...
Position sensorless control of a transverse-laminated reluctance synchronous machine
(Stellenbosch : Stellenbosch University, 2014-12)
ENGLISH ABSTRACT: The focus of this thesis is position sensorless control of a transverse-laminated reluctance
synchronous machine. Rotor position information is required for high-performance closedloop
control of the ...
