  • Brooks, Clive Raymond (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The main focus of this thesis is to document the formulation, extraction and validation of nonlinear models for the on-wafer gallium nitride (GaN) high-electron mobility (HEMT) devices manufactured at ...
  • Esterhuizen, Gerhard (Stellenbosch : University of Stellenbosch, 2003-03)
    ENGLISH ABSTRACT: Probability density functions (PDFs) and cumulative distribution functions (CDFs) play a central role in statistical pattern recognition and verification systems. They allow observations that do not ...
  • Le Riche, Pierre (Pierre Jacques) (Stellenbosch : Stellenbosch University, 2000-12)
    ENGLISH ABSTRACT: Handwritten signature verification (HSV) is the process through which handwritten signatures are analysed in an attempt to determine whether the person who made the signature is who he claims to ...
  • Sindle, Colin (Stellenbosch : Stellenbosch University, 2003-12)
    ENGLISH ABSTRACT: Handwritten signatures are provided extensively to verify identity for all types of transactions and documents. However, they are very rarely actually verified. This is because of the high cost of ...
  • Krige, Ernst (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: The implementation of the Caprivi Link Interconnector (CLI) High Voltage Direct Current (HVDC) scheme in 2010 connecting the weak Namibian and Zambian Alternating Current (AC) transmission networks via ...
  • McIver, Stuart Roderick Arthur (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The thesis details the design, construction and experimental evaluation of 30W, 35W and 250W L-Band LDMOS Radar amplifiers. Each amplifier module contains an integrated high speed power supply in order ...
  • Van Rhyn, P. D. (Stellenbosch : University of Stellenbosch, 2006-03)
    This thesis presents the design and implementation of a high voltage DC-DC converter using a series stacked topology. The converter’s specifications were set by Spoornet and the converter forms part of a DC-AC inverter ...
  • Stander, Tinus (Stellenbosch : University of Stellenbosch, 2009-12)
    ENGLISH ABSTRACT: This dissertation presents a synthesis method for broadband high-power absorptive microwave lters by cascading a wide stop-band wa e-iron lter with an absorptive harmonic pad. The classical image ...
  • Snetler, Lukas Hendrick (Stellenbosch : University of Stellenbosch, 2005-03)
    High-temperature superconductive (HTS) logic has become a large research field worldwide. The HTS advantages compared to the low-temperature circuits are the reduced cooling requirements, increased or comparable operation ...
  • Krige, Willie (Stellenbosch : Stellenbosch University, 2008-03)
    A singing transcription system transforming acoustic input into MIDI note sequences is presented. The transcription system is incorporated into a pronunciation-independent sight-singing tutor system, which provides ...
  • Northeast, David Bernard (Stellenbosch : University of Stellenbosch, 2011-03)
    ENGLISH ABSTRACT: The design and simulation of hot electron bolometer sensors for the detection of millimeter and terahertz wave radiation is presented. These devices can be used for the formation of images or for ...
  • Wilson, John E. (Stellenbosch : University of Stellenbosch, 2009-03)
    This thesis details the development and comparison of two linear control systems that performhover control for a vertical take-off and landing unmanned aerial vehicle. A non-linear mathematical model of the aircraft ...
  • Lezar, Evan (Stellenbosch : Stellenbosch University, 2008-03)
    The nite element method (FEM) is a powerful tool for the computational analysis of a wide range of electromagnetic problems. As the complexity of the problems is increased so are the demands in terms of the computational ...
  • Ellis, Loftie (Stellenbosch : University of Stellenbosch, 2007-12)
    In this thesis we present a human-computer interface (HCI) system for disabled persons using only a basic web camera. Mouse movements are simulated by small movements of the head, while clicks are simulated by eye blinks. ...
  • Groch, Matthew (Stellenbosch : Stellenbosch University, 2013-12)
    ENGLISH ABSTRACT: The deployment of Unmanned Aerial Vehicles (UAV) for power line inspection requires the definition of safe-fly zones. Transient Over-Voltages (TOVs) on the Overhead Transmission Lines (OHTLs) put the ...
  • Meyer, Frans J. C. (Frans Johannes Christiaan) (Stellenbosch : Stellenbosch University, 1991-02)
    ENGLISH ABSTRACT: A two-dimensional Coupled Element Method (CEM) for solving electromagnetic scattering problems involving lossy, inhomogeneous, arbitrarily shaped cylinders, was investigated and implemented. The CEM ...
  • Nazo, Syanda (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: Radar Cross Section (RCS) is an important parameter in radar engineering. Often, electrically large structures are of interest in RCS analysis due to the high operating frequencies of radar systems. ...
  • Croucher, Darren Armstrong (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: Massively Multiplayer Online Games are large virtual worlds co-inhabited by players over the Internet. As up to thousands of players can be simultaneously connected to the game, the server and network ...
  • Holtzhausen, Petrus Jacobus (Stellenbosch : University of Stellenbosch, 2006-12)
    A radar system observes an aircraft once during each scan of the airspace, and uses these observations to construct a track representing a possible route of the aircraft. However when aircraft interact closely there is the ...
