• 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
