Theses and Dissertations (Computer Science): Recent submissions

  • Cone normal stepping 
    Burger, Divan Desmond (University of Pretoria, 2018)
    This dissertation examines several methods of relief mapping, such as parallax mapping and cone step mapping, as well as methods for soft shadowing and ambient occlusion of relief maps. Ambient occlusion is an approximation ...
  • Forensic attribution challenges during forensic examinations of databases 
    Hauger, Werner Karl (University of Pretoria, 2018)
    An aspect of database forensics that has not yet received much attention in the academic research community is the attribution of actions performed in a database. When forensic attribution is performed for actions executed ...
  • A new dialect of SOFL-Syntax formal semantics and tool support 
    van der Berg, Johan Sarel (University of Pretoria, 2018)
    Structured Object Orientated Formal Language (SOFL) is a formal method design methodology that combines data flows diagrams and predicates in order to describe processes that can be refined. This methodology creates a very ...
  • Fast Data Analysis Methods For Social Media Data 
    Nhlabano, Valentine Velaphi (University of Pretoria, 2018-08-07)
    The advent of Web 2.0 technologies which supports the creation and publishing of various social media content in a collaborative and participatory way by all users in the form of user generated content and social networks ...
  • The influence of fitness landscape characteristics on the search behaviour of particle swarm optimisers 
    Bosman, Phlippie Rudolph (University of Pretoria, 2019)
    Fitness landscapes facilitate the analysis of optimisation problems in a detailed, yet intuitive manner. Such an analysis can be used to select an appropriate algorithm to solve the problem, based on the strengths and ...

  • Case study research as a method for digital forensic evidence examinations 
    Oyelami, Oluwasayo Oyeyemi (University of Pretoria, 2018)
    At the heart of any forensic science discipline, there is the need to ensure that the method applied in the discipline is based on a valid scienti c method. The aim of any forensic examination is to make veri able and ...
  • A Digital Forensic Readiness Approach for e-Supply Chain Systems 
    Masvosvere, Derek Jens Emeth (University of Pretoria, 2019)
    The internet has had a major impact on how information is shared within supply chains, and in commerce in general. This has resulted in the establishment of information systems such as esupply chains (eSCs) amongst others ...
  • An intelligent method of predicting insurance claims fraud 
    Kenyon, David Leicester (University of Pretoria, 2018)
    Insurance fraud costs South Africa (and the global insurance industry) billions of Rands. Insurance claims fraud, which involves over-inflating claim amounts or fabricating a loss to result in a claim settlement, makes up ...
  • Driving dynamic multi-objective optimizations constrained by decision-makers' preferences 
    Adekoya, Adekunle Rotimi (University of Pretoria, 2019)
    Dynamic multi-objective optimization problems (DMOOPs) are an interesting and a relatively complex class of optimization problems where elements of the problems, such as objective functions and/or constraints, change ...
  • Evaluation and Identification of Authentic Smartphone Data 
    Pieterse, Heloise (University of Pretoria, 2019-07-09)
    Mobile technology continues to evolve in the 21st century, providing end-users with mobile devices that support improved capabilities and advance functionality. This ever-improving technology allows smartphone platforms, ...
  • Digital Forensic Readiness Architecture for Cloud Computing Systems 
    Ras, Dirk J. (University of Pretoria, 2019)
    Cloud computing underpins many of the current emergent and established technologies. As a result, cloud computing has an impact on many components of our daily lives, be it from online shopping and banking to usage of ...
  • Fitness Landscape Analysis of Feed-Forward Neural Networks 
    Bosman, Anna Sergeevna (University of Pretoria, 2019)
    Neural network training is a highly non-convex optimisation problem with poorly understood properties. Due to the inherent high dimensionality, neural network search spaces cannot be intuitively visualised, thus other means ...
  • A model for digital evidence admissibility assessment 
    Antwi-Boasiako, Albert (University of Pretoria, 2018)
    Riding on the tide of the current development in computing and internet technologies, criminals have transitioned to the use of computer systems and digital channels to commit crimes. This transformation of crime requires ...
  • Time series forecasting using dynamic particle swarm optimizer trained neural networks 
    Abdulkarim, Salihu Aish (University of Pretoria, 2018)
    Time series forecasting is a very important research area because of its practical application in many elds. Due to the importance of time series forecasting, much research e ort has gone into the development of forecasting ...
  • Social Engineering Attack Detection Model 
    Mouton, Francois (University of Pretoria, 2018-11)
    Information security is a fast-growing discipline, and relies on continued improvement of security measures to protect sensitive information. Human operators are one of the weakest links in the security chain as they are ...
  • Digital Forensic Readiness in Mobile Device Management Systems 
    Ros, Elsabe (University of Pretoria, 2018)
    Mobile devices have become very popular, and virtually everyone owns a smart device. As more employees became owners of smart devices, the organisations were put under pressure to allow employees to use their smart devices ...
  • Co-evolved genetic program for stock market trading
