  • Modelling of end-pumped Ho:YLF amplifiers 
    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 ...
  • Development and application of tunable VUV laser sources 
    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 ...
  • Geodesics and resonances of the Manko-Novikov spacetime 
    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, ...
  • Spectral and temporal modulation and characterization of femtosecond ultra-short laser pulses 
    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 ...
  • Terahertz (THz) spectroscopy 
    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 ...
  • A quantum hall effect without landau levels in a quasi one dimensional system 
    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 ...
  • Theoretical investigation of dielectrophoresis and electrophoresis as techniques for silver deflections 
    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 ...
  • Scattering in soliton models and crossing symmetry 
    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 ...
  • Numerical design of an optical solid-state amplifier 
    Van der Westhuizen, Gysbert Johannes (Stellenbosch : Stellenbosch University, 2007-12)
    Please refer to full text for abstract
  • Assessment of microbial levels in the Plankenburg and Eerste Rivers and subsequent carry-over to fresh produce using source tracking as indicator 
    Huisamen, Nicola (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: The agricultural sector of South Africa is currently facing a serious water crisis. The decreased availability of water as a result of climate change and the constantly growing population has left many ...
  • Statistical thermodynamics of long-range quantum spin systems 
    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 ...
  • Density functional calculation of simple molecules 
    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 ...
  • Ultrafast electron diffraction on the charge density wave compound 4Hb-TaSe2 
    Boshoff, Ilana (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: Ultrafast electron diffraction is a powerful method to study atomic movement in crystals on sub-picosecond timescales. This thesis consists of three parts. In part one the ultrafast electron diffraction ...
  • Test of fast neutron detectors for spectroscopy with (3He,n) two proton stripping reactions 
    Elbasher, Mohamed Elbasher Ahmed (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: Nine 100x100x600 mm3 plastic scintillators, formerly built for the neutron time of ight measurements at iThemba LABS, were refurbished. The position resolution of these detectors was determined using ...
  • A non-commutative walecka model as an effective theory for interacting nucleons of finite size 
    Groenewald, Hendrikus Wilhelm. (Stellenbosch : Stellenbosch University, 2012-03)
    ENGLISH ABSTRACT: The nite size of nucleons should play an important role in the description of high density nuclear matter as found in astro-physical objects. Yet we see that the Walecka model, which is generally used ...
