  • Gumede, Sthembiso R. (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: The advent of the synthesis or manufacturing of controlled structures on submicron scales as well as experimental developments enabling the investigation of physics in speci c biological systems at ...
  • Steyn, Ruan (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: Non-destructive portable X-ray Fluorescence (pXRF) and Particle Induced X-ray Emission (PIXE) were used to measure the elemental concentration of rock art fragment paintings. For pXRF the Amptek Silicon ...
  • Kimene Kaya, Boniface Dimitri Christel (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: We present a theoretical approach that allows for the description of trapped Bose-Fermi mixtures with a tunable interspecies interaction in the vicinity of a Feshbach resonance magnetic field.The many-body ...
  • Astl, Stefan Ludwig (Stellenbosch : Stellenbosch University, 2013-12)
    ENGLISH ABSTRACT: Techniques for estimating a signal in the presence of noise which contains outliers are currently not well developed. In this thesis, we consider a constant signal superimposed by a family of noise ...
  • Coetzee, Riaan Stuart (Stellenbosch : Stellenbosch University, 2013-12)
    ENGLISH ABSTRACT: The following work focuses on the development and characterization of efficient, high-power, Thulium doped fibre lasers. Lasers emitting light around ~2 μm have generated a large amount of interest owing ...
  • Elnour, Huzifa Mohammed Ahamed Mohammed (Stellenbosch : Stellenbosch University, 2013-12)
    ENGLISH ABSTRACT: A Magneto Optical Trap (MOT) is a configuration formed by three orthogonal pairs of counterpropagating circularly polarized laser beams and a magnetic field gradient. A MOT is used to cool, capture and ...
  • Okoye, Raphael (Stellenbosch : Stellenbosch University, 2013-12)
    ENGLISH ABSTRACT: An ultra-fast laser pulse can be described in the time or frequency domain. If the timebandwidth product of an ultra-fast pulse is not satisfied, then the pulse is stretched. Stretching can be described ...
  • Collett, Oliver John Philip (Stellenbosch : Stellenbosch University, 2013-03)
    This work is a thesis regarding the energy scaling of end-pumped Ho:YLF amplifiers. The work includes: a brief review of laser physics and models, the development of a suitable three dimensional time resolved numerical ...
  • Nortje, Anton Christiaan (Stellenbosch : Stellenbosch University, 2013-03)
    ENGLISH ABSTRACT: A tunable narrow-bandwidth vacuum ultra violet laser source was developed and characterised. Two-photon resonant four-wave sum-frequency mixing of two pulsed dye laser beams in magnesium vapour was used ...
  • Geyer, Marisa (Stellenbosch : Stellenbosch University, 2013-03)
    ENGLISH ABSTRACT: In this thesis I study compact objects described by the Manko-Novikov spacetime. The Manko- Novikov spacetime is an exact solution to the Einstein Field Equations that allows objects to be black hole-like, ...
  • Mbanda Nsoungui, Gaelle Carine (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: Ultra-short laser pulses are useful in materials processing like melting and cutting metals, and medical applications such as surgery and many other fields. In this study, we characterize and control ...
  • Numan, Nagla Numan Ali (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: Terahertz radiation is currently used in security, information and communication technology (ICT), and biomedical sciences among others. The usability of terahertz (THz) radiation, in many of its ...
  • Brand, Janetta Debora (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: The experimental observation of the quantum Hall effect in a two-dimensional electron gas posed an intriguing question to theorists: Why is the quantization of conductance so precise, given the imperfections ...
  • Mokgalapa, Naphtali Malesela (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: The primary circuit components of very high temperature reactors (VHTRs) experience various unwanted fission products such as Kr, Xe, I, Cs, Sr, and Ag. These particle are generated during normal ...
  • Abdelhady, A. M. H. H. (Stellenbosch : Stellenbosch University, 2012-12)
    ENGLISH ABSTRACT: Crossing symmetry relates scattering and annihilation processes to each other. Its derivation is straightforward in perturbative approaches to quantum field theory: it merely reflects the exchange of ...
  • Bartlett, Bruce (Stellenbosch : Stellenbosch University, 2003-03)
    ENGLISH ABSTRACT: This thesis presents an overview of the flow equations recently introduced by Wegner. The little known mathematical framework is established in the initial chapter and used as a background for the entire ...
  • Boonzaaier, Leandro (Stellenbosch : Stellenbosch University, 2002-12)
    ENGLISH ABSTRACT: In this thesis we give an overview of self-organised criticality and its application to studying seismicity. We recall some of the basic models and techniques for studying self-organised critical systems. ...
  • Van der Westhuizen, Gysbert Johannes (Stellenbosch : Stellenbosch University, 2007-12)
    Please refer to full text for abstract
  • Olivier, G. J. F. (Gerrit Jacobus Francois) (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT:In this thesis we discuss some of the anomalies present in systems with long-range interactions, for instance negative speci c heat and negative magnetic susceptibility, and show how they can be related ...
  • Olaoye, Olufemi Opeyemi. (Stellenbosch : Stellenbosch University, 2012-03)
    AFRIKAANSE OPSOMMING: Berekeninge met Density Functional Theory (DFT) is ’n nuttige tegniek om die dinamika van molekules op potensiële energievlakke te verstaan. Beginnende met ’n prototipe molekuul formaldimien, wat ...
