  • Ramonyalioa, Thethe Tshepo (Stellenbosch : Stellenbosch University, 2003-04)
    ENGLISH ABSTRACT: This thesis investigates the viability of implementing the AX.25 protocol in Java, for satellite applications. The AX.25 protocol forms part of the Communications subsystem of a micro-satellite. It ...
  • Nkadimeng, Calvin (Stellenbosch : University of Stellenbosch, 2010-03)
    ENGLISH ABSTRACT: The importance of Language Identification for African languages is seeing a dramatic increase due to the development of telecommunication infrastructure and, as a result, an increase in volumes of data ...
  • Olivier, Francois Jacobus (Stellenbosch : University of Stellenbosch, 2009-12)
    ENGLISH ABSTRACT: Low earth orbit (LEO) satellite communication presents a unique environment which inherently di ers from most other communication channels. Due to the varying orbital patterns of LEO satellites the link ...
  • De Wit, W. M. (Stellenbosch : University of Stellenbosch, 2006-03)
    The topic of millimeter wave radar systems is introduced. These radars are used in a wide range of applications in both the aviation and automotive field due to the resolution advantages which MMW systems have above their ...
  • Kritzinger, Carl (Stellenbosch : University of Stellenbosch, 2006-03)
    Despite enormous advances in digital communication, the voice is still the primary tool with which people exchange ideas. However, uncompressed digital speech tends to require prohibitively high data rates (upward of ...
  • Jacobs, M. J. (Stellenbosch : University of Stellenbosch, 1995-12)
    ENGLISH ABSTRACT: The Sunsat microsatellite is being developed at the University of Stellenbosch. It is equipped with a high resolution earth imager which requires a sophisticated attitude determination and control system. ...
  • Malan, Pieter Jacob De Villiers (Stellenbosch : University of Stellenbosch, 2005-12)
    In RF power transistor characterisation, the designer is confronted with low impedance measurements (typically from 1 Ohm to 12 Ohm). These transistors are contained in metal-ceramic packages of which the lead widths ...
  • Moes, Henderikus Jan (Stellenbosch : Stellenbosch University, 2008-03)
    This thesis discusses the design, development and measured results of a phase-locked loop based frequency synthesiser for X-band Doppler radar. The objective is to obtain phase noise comparable or lower than that typically ...
  • Van Wyk, Carel (Stellenbosch : University of Stellenbosch, 2011-03)
    ENGLISH ABSTRACT: The computational power of mobile smart-phone devices are ever increasing and high-end phones become more popular amongst consumers every day. The technical speci cations of a high-end smart-phone today ...
  • Bekker, Bernard (Stellenbosch : Stellenbosch University, 2004-12)
    ENGLISH ABSTRACT: This thesis investigates methods to extract the maximum amount of electrical energy from a py panel. The thesis is divided into four parts, focussing on different aspects relating to this topic. The ...
  • Badenhorst, J. (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 ...
  • Van der Merwe, Benjamin (Stellenbosch : Stellenbosch University, 2001-04)
    ENGLISH ABSTRACT: This thesis describes various software technologies implemented, or specifically developed, for the SUNSAT micro-satellite mission. With the discussion centered on the Mission Operations System functions ...
  • Geldenhuys, N. D. (Stellenbosch : Stellenbosch University, 2001-03)
    ENGLISH ABSTRACT: The topic of microwave frequency discriminators is introduced. Various applications and implementation techniques of these devices are given and discussed. This thesis may serve as reference foundation ...
  • Kotze, Daniel Johannes Van Wyk (Stellenbosch : University of Stellenbosch, 2011-03)
    ENGLISH ABSTRACT: An investigation is made to find a suitable routing protocol for a millimeter wave ad hoc wireless network. It is discovered that a hierarchical routing protocol is ideal for a high node density. Due to ...
  • Schoeman, Marlize (Stellenbosch : University of Stellenbosch, 2003-12)
    ENGLISH ABSTRACT: A complete mixed-potential integral equation formulation for the analysis of arbitrarily shaped scatterers in a planarly layered medium is presented. The integral equation is able to solve for simultaneous ...
  • Chewele, Youngie Klyv (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: The development of fast and efficient processors, programmable devices and high power semiconductors has led to the increased use of semiconductors directly in the power supply path in order to achieve ...
  • Rossouw, Jacques Stefan (Stellenbosch : Stellenbosch University, 2004-04)
    ENGLISH ABSTRACT: Improvements in the area of satellite orientation control in the presence of large actuator gain changes are investigated. Gain changes primarily originate from actuator failures, but may also result ...
  • Du Plessis, J. Prieur (Stellenbosch : Stellenbosch University, 2002-03)
    ENGLISH ABSTRACT: A Representative Unit Cell (RUC) model for flow through two-dimensional porous media is presented and applied to two industrial related problems. The first application is to that of cross-flow in tube ...
  • Van der Merwe, S (Stellenbosch : University of Stellenbosch, 2006-12)
    This research project investigates the design, modelling and application of an open-air capacitive voltage sensor assembly for the measurement of wideband High Voltage signals on three-phase transmission lines. The ...
  • Shifidi, S. K. (Stellenbosch : University of Stellenbosch, 2009-12)
    ENGLISH ABSTRACT: From a systems operation and design perspective, it is important to understand the behaviour of HVDC system insulation when presented with high voltage transients, such as induced by lightning and ...
