  • Fourie, Coenrad Johann (Stellenbosch : Stellenbosch University, 2001-03)
    ENGLISH ABSTRACT: Rapid Single Flux Quantum (RSFQ) logic cells are discussed, and new cells developed. The expected yield of every cell is computed through a Monte Carlo analysis, and where necessary these cells are ...
  • Fourie, Gerhardus Johannes (Stellenbosch : University of Stellenbosch, 2006-12)
    This thesis relates to the design and characterization of a 10 kW L-band power combiner consisting of 8 input ports. The design is implemented in a non-radial planar transmission line architecture and operates between ...
  • De Villiers, J. W. L. (Stellenbosch : University of Stellenbosch, 2006-12)
    Modelling of the transport of fine cohesive sediments, as found in most South African reservoirs, has not been well developed. This is because the transport processes that are involved are complex and the theories not ...
  • Kilian, Anton Theo (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: This work discusses the design of a 3-axis Geomagnetometer SQUID System (GSS), in which HTS SQUIDs are used unshielded. The initial GSS installed at SANSA was fully operable, however the LN2 evaporation ...
  • Eriksson, Anders (Stellenbosch : Stellenbosch University, 1999-12)
    ENGLISH ABSTRACT: In recent years face recognition has been a focus of intensive research but has still not achieved its full potential, mainly due to the limited abilities of existing systems to cope with varying pose ...
  • Malan, Daniel Francois (Stellenbosch : University of Stellenbosch, 2005-03)
    Visually estimating three-dimensional position, orientation and motion, between an observer and a target, is an important problem in computer vision. Solutions which compute threedimensional movement from two-dimensional ...
  • Janssens, M.   Van Wijck, W.   Du Preez, N. D. (Department of Industrial Engineering, Stellenbosch University, 1999)
    ENGLISH ABSTRACT: This paper presents a method to automatically extract analytical entities like planes, spheres and cylinders from a file containing a cloud of points. The method facilitates the manipulation and reduction ...
  • Mostert, Sias (Stellenbosch : Stellenbosch University, 2000-12)
    ENGLISH ABSTRACT: The engineering of dependable real-time systems for mission critical applications is a resource intensive and error prone process. Achieving dependability requires a general consensus on the correctness ...
  • Steyn, Willem Hermanus (Stellenbosch : Stellenbosch University, 1995-12)
    ENGLISH ABSTRACT: New advanced control techniques for attitude determination and control of small (micro) satellites are presented. The attitude sensors and actuators on small satellites are limited in accuracy and ...
  • Walubita, Lubinda F. (Stellenbosch : Stellenbosch University, 2000-12)
    ENGLISH ABSTRACT: Accelerated pavement testing (APT) is the application of a wheel loading, to a prototype or actual layered, structural pavement system to determine pavement response and performance under controlled, ...
  • Peddle, Iain K. (Stellenbosch : Stellenbosch University, 2008-12)
    ENGLISH ABSTRACT: A strategy for the design of an effective, practically feasible, robust, computationally efficient autopilot for three dimensional manoeuvre flight control of Unmanned Aerial Vehicles is presented. The ...
  • Peddle, Iain K. (Stellenbosch : Stellenbosch University, 2008-12)
    A strategy for the design of an effective, practically feasible, robust, computationally efficient autopilot for three dimensional manoeuvre flight control of Unmanned Aerial Vehicles is presented. The core feature of ...
  • Alberts, Frederik Nicolaas (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: This thesis presents the analysis, design, simulation and practical implementation of a control system to achieve an accurate autonomous landing of a fixed-wing unmanned aerial vehicle in the presence ...
  • Schulze, Shaun (Stellenbosch : University of Stellenbosch, 2006-12)
    A great demand exits for higher data rates and increased reliability of future consumer based mobile communication systems while being more bandwidth and power efficient. Orthogonal frequency division multiplexing (OFDM) ...
  • Hansmann, Chirstine Henriette (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 ...
  • Van Wyk, M. D. (Stellenbosch : University of Stellenbosch, 2002-12)
    An efficient radiating strucllire was needed for borehole pulsed radar applications in the 10-100 MHz frequency band. Both resistively loaded and insulated wire antennas were investigated and an active antenna is proposed ...
  • Cawood, Andrew Dudley (Stellenbosch : University of Stellenbosch, 2006-12)
    A low earth orbit satellite is to provide the telecommunications link to facilitate email services to rural areas, where the infrastructure necessary for e-mail is lacking (e.g. no telephone lines). Communication time ...
  • Els, Ellis Raymond (Stellenbosch : Stellenbosch University, 2000-12)
    ENGLISH ABSTRACT: Adsorption tests were conducted with four different ion-exchange resins to determine the equilibrium adsorption of a range of precious and base metals. The adsorption characteristics were determined ...
  • Goliath, Elroy Mario (Stellenbosch : Stellenbosch University, 2002-03)
    ENGLISH ABSTRACT: This study describes the design, construction, complete industrialisation and operation of a dual bed vacuum swing adsorption (VSA) demonstration plant, which operates at atmospheric and sub-atmospheric ...
  • Haasbroek, Adriaan Lodewicus (Stellenbosch : Stellenbosch University, 2013-03)
    ENGLISH ABSTRACT: This work focussed on a local multiple chamber falling film evaporator (FFE). The FFE is currently under operator control and experiencing large amounts of lost production time due to excessive fouling. ...
