  • Assessing quality in software engineering : a pragmatic approach 
    Acton, Daniel (University of Pretoria, 2013)
    As long as software has been produced, there have been efforts to strive for quality in software products. In order to understand quality in software products, researchers have built models of software quality that rely ...
  • An assessment of selected algorithms for generating failure deterministic finite automata 
    Nxumalo, Madoda (University of Pretoria, 2016)
    A Failure Deterministic Finite Automaton (FDFA) o ers a deterministic and a compact representation of an automaton that is used by various algorithms to solve pattern matching problems e ciently. An abstract, concept lattice ...
  • The Axial line placement problem 
    Sanders, Ian Douglas (University of Pretoria, 2005-10-17)
    Visibility, guarding and polygon decomposition are problems in the field of compu¬tational geometry which have roots in real world applications. These problems have been the focus of much research over a number of years. ...
  • A case-study based assessment of Agile software development 
    Theunissen, William Herman Morkel (University of Pretoria, 2005-09-30)
    This study set out to determine various aspects of the agile approaches to software development. These included an investigation into the principles and practices driving these methodologies; determining the applicability ...
  • Constructing concept lattices and compressed pseudo-lattices 
    Van der Merwe, Frederik Johannes (University of Pretoria, 2006-09-22)
    Please read the abstract in the section 00front of this document
  • Constructing minimal acyclic deterministic finite automata 
    Watson, Bruce William (University of Pretoria, 2010)
    This thesis is submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Ph.D) in the FASTAR group of the Department of Computer Science, University of Pretoria, South Africa. I present ...
  • A critical analysis of two refactoring tools 
    Drozdz, Martin Zbigniew (University of Pretoria, 2008-08-19)
    This study provides a critical analysis of refactoring by surveying the refactoring tools in IDEA and Eclipse. Ways are discussed to locate targets for refactorings, via detection of code smells from static code analysis ...
  • Design and implementation of a high resolution soft real-time timer 
    Grobler, Johannes Petrus (University of Pretoria, 2007-09-04)
    There are several timing mechanisms on presently available commercial operating systems. Two operating system platforms that immediately come to mind are the Microsoft Windows environment (the WIN32 platform) and its ...
  • Developing a consumer health informatics decision support system using formal concept analysis 
    Horner, Vincent Zion (University of Pretoria, 2008-08-07)
    A consumer health decision support system (CDSS) is being developed at the South African Medical Research Council (MRC). It is a software program intended to help members of the public decide when they may be at risk of ...
  • An empirically derived system for high-speed rendering 
    Rautenbach, Helperus Ritzema (University of Pretoria, 2012-09-26)
    This thesis focuses on 3D computer graphics and the continuous maximisation of rendering quality and performance. Its main focus is the critical analysis of numerous real-time rendering algorithms and the construction of ...
  • An empirically derived system for high-speed shadow rendering 
    Rautenbach, Helperus Ritzema (University of Pretoria, 2009-06-29)
    Shadows have captivated humanity since the dawn of time; with the current age being no exception – shadows are core to realism and ambience, be it to invoke a classic Baroque interplay of lights, darks and colours as the ...
  • An exposition of the nature of volunteered geographical information and its suitability for integration into spatial data infrastructures 
    Cooper, Antony Kyle (University of Pretoria, 2016)
    This thesis presents an analysis of the nature of volunteered geographical information (VGI) and on its applicability for use in a spatial data infrastructure (SDI) to supplement official and commercial sources, particularly ...
  • Fine-grain transformations for refactoring 
    Saadeh, Emmad I.M. (University of Pretoria, 2009)
    This thesis proposes a new approach to formalize refactorings, principally at the UML class diagram design level (but incorporating a limited amount of code-level information—basic access-related information). A set of ...
  • Fingerprinting Encrypted Tunnel Endpoints 
    Izadinia, Vafa Dario (University of Pretoria, 2005)
    Operating System fingerprinting is a reconnaissance method used by Whitehats and Blackhats alike. Current techniques for fingerprinting do not take into account tunneling protocols, such as IPSec, SSL/TLS, and SSH, which ...
  • Finite state automaton construction through regular expression hashing 
    Coetser, Rayner Johannes Lodewikus (University of Pretoria, 2009)
    In this study, the regular expressions forming abstract states in Brzozowski’s algorithm are not remapped to sequential state transition table addresses as would be the case in the classical approach, but are hashed to ...
  • Flexible finite automata-based algorithms for detecting microsatellites in DNA 
    De Ridder, Corne (University of Pretoria, 2010-09-13)
    Apart from contributing to Computer Science, this research also contributes to Bioinformatics, a subset of the subject discipline Computational Biology. The main focus of this dissertation is the development of a data-analytical ...
