• Sensitivity analysis of multilayer neural networks 

      Engelbrecht, Andries Petrus (Stellenbosch : Stellenbosch University, 1999-12)
      ENGLISH ABSTRACT: The application of artificial neural networks to solve classification and function approximation problems is no longer an art. Using a neural network does not simply imply the presentation of a data set ...
    • Solving embedding problems with bounded ramification 

      Ramiharimanana, Nantsoina Cynthia (Stellenbosch : Stellenbosch University, 2016-12)
      ENGLISH ABSTRACT : Given a Galois extension K/K0 of number fields, a finite group G, and an epimorphism α: G→ Gal(K/K0) with solvable kernel, our goal is to embed K into a Galois extension N of K0 with Galois group ...
    • Spectral theory in commutatively ordered banach algebras 

      Muzundu, Kelvin (Stellenbosch : Stellenbosch University, 2012-12)
      ENGLISH ABSTRACT: See full text.
    • Spreading waves of invasive species 

      Ramanantoanina, Andriamihaja (Stellenbosch : Stellenbosch University, 2014-03)
      ENGLISH ABSTRACT: Invasive species are well known to harm economy as well as ecological assets and impair ecosystems functioning around the world. Timely control and management of new incursions of invasive species ...
    • Stochastic visual tracking with active appearance models 

      Hoffmann, McElory Roberto (Stellenbosch : University of Stellenbosch, 2009-12)
      ENGLISH ABSTRACT: In many applications, an accurate, robust and fast tracker is needed, for example in surveillance, gesture recognition, tracking lips for lip-reading and creating an augmented reality by embedding a ...
    • Structure-from-motion for enclosed environments 

      Hakl, Henri (Stellenbosch : University of Stellenbosch, 2007-12)
      A structure-from-motion implementation for enclosed environments is presented. The various aspects covered include a discussion on optimised luminance computations—a technique to compute an optimally weighted luminance ...
    • A topological framework for modeling belief revision 

      Jeftha, Lindsey Craig (Stellenbosch : University of Stellenbosch, 2010-12)
      ENGLISH ABSTRACT: Classical formulations model belief revision as a deterministic process. Under certain circumstances, the process may have more than one outcome, which suggests that belief revision is non-deterministi ...
    • Two new combinatorial problems involving dominating sets for lottery schemes 

      Grundlingh, Werner R. (Stellenbosch : University of Stellenbosch, 2004-12)
      Suppose a lottery scheme consists of randomly selecting an unordered winning n-subset from a universal set of m numbers, while a player participates in the scheme by purchasing a playing set of any number of unordered ...
    • A video-based traffic monitoring system 

      Magaia, Lourenco Lazaro (Stellenbosch : University of Stellenbosch, 2006-12)
      This thesis addresses the problem of bulding a video-based traffic monitoring system. We employ clustering, trackiing and three-dimensional reconstruction of moving objects over a long image sequence. We present an ...
    • Weighted centrality, and a further approach to categorical commutativity 

      Shaumbwa, Vaino Tuhafeni (Stellenbosch : Stellenbosch University, 2019-12)
      ENGLISH ABSTRACT: We investigate weighted commutators, that is, weighted subobject commutator and weighted normal commutator, as well as commutators in the sense of Huq, Higgins, Ursini and Smith, which are all special ...
