  • A comparative study on the impact of different fluxes in a discontinuous Galerkin scheme for the 2D shallow water equations 

    Rasolofoson, Faraniaina (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: Shallow water equations (SWEs) are a set of hyperbolic partial differential equations that describe the flow below a pressure surface in a fluid. They are widely applicable in the domain of fluid dynamics. ...
  • Modelling the dynamics of HIV related malignancies 

    Akinlotan, Deborah Morenikeji (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: In recent years, HIV-associated cancers have proven to be the bane of our time, since HIV is decimating humanity across the globe, even in the twilight of the last century. Cancer rates continue to rise ...
  • Grain regression analysis 

    Sullwald, Wichard (Stellenbosch : Stellenbosch University, 2014-04)

    Basson, Dirk Johannes (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: Rank 2 Drinfeld modular forms have been studied for more than 30 years, and while it is known that a higher rank theory could be possible, higher rank Drinfeld modular forms have only recently been de ...
  • Decision forests for computer Go feature learning 

    Van Niekerk, Francois (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: In computer Go, moves are typically selected with the aid of a tree search algorithm. Monte-Carlo tree search (MCTS) is currently the dominant algorithm in computer Go. It has been shown that the inclusion ...
  • Investigating the effect of compression on the permeability of fibrous porous media 

    Van Heyningen, Martha Catharina (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: Fluid flow through porous media plays an important role in a variety of contexts of which filtration is one. Filtration efficiency of fibrous filters depends on the micro-structural characterization of ...
  • Random walks on graphs 

    Oosthuizen, Joubert (Stellenbosch : Stellenbosch University, 2014-04)
    ENGLISH ABSTRACT: We study random walks on nite graphs. The reader is introduced to general Markov chains before we move on more specifically to random walks on graphs. A random walk on a graph is just a Markov chain ...
  • Model checking rational agents 

    Bordini, Rafael H.; Fisher, Michael; Wooldridge, Michael; Visser, Willem (IEEE - -Institute of Electrical and Electronics Engineers, 2004-10)
    Agent-oriented programming techniques seem appropriate for developing systems that operate in complex, dynamic, and unpredictable environments. We aim to address this requirement by developing model-checking techniques for ...
  • Property-based slicing for agent verification 

    Bordini, Rafael H.; Fisher, Michael; Wooldridge, Michael; Visser, Willem (Oxford University Press (OUP), 2009-12)
    Programming languages designed specifically for multi-agent systems represent a new programming paradigm that has gained popularity over recent years, with some multi-agent programming languages being used in increasingly ...
  • A survey of new trends in symbolic execution for software testing and analysis 

    Pasareanu, Corina S.; Visser, Willem (Springer Verlag, 2009-10)
    Symbolic execution is a well-known program analysis technique which represents program inputs with symbolic values instead of concrete, initialized, data and executes the program by manipulating program expressions involving ...
