Theses and Dissertations (Computer Science): Recent submissions

  • A near-miss analysis model for improving the forensic investigation of software failures 
    Bihina Bella, Madeleine (University of Pretoria, 2014)
    The increasing complexity of software applications can lead to operational failures that have disastrous consequences. In order to prevent the recurrence of such failures, a thorough post-mortem investigation is required ...
  • Set-Based Particle Swarm Optimization 
    Langeveld, Joost (University of Pretoria, 2016)
    Particle swarm optimization (PSO) algorithms have been successfully applied to discrete-valued optimization problems. However, in many cases the algorithms have been tailored specifically for the problem at hand. This study ...
  • Light beam tracing for multi-bounce specular and glossy transport paths 
    Duvenhage, Bernardt (University of Pretoria, 2015)
    Light beam tracing is an e cient rendering algorithm for simulating caustics, the envelopes of light that are scattered from shiny curved surfaces and focussed into lines or spots of concentrated light. Light beam tracing ...
  • A comprehensive and harmonised digital forensic investigation process model 
    Valjarevic, Aleksandar (University of Pretoria, 2015)
    Recent decades have seen a significant increase in the importance of the field of digital forensics as a result of the rapid development of information and communication technologies and their penetration into every ...
  • XML accounting trail : a model for introducing forensic readiness to XML accounting and XBRL 
    Kotze, Dirk J.J. (University of Pretoria, 2015)
    In the 21st century, our worlds are becoming increasingly digitised and the business world is no exception. Financial transactions and accounting data are stored electronically, allowing for sharing and electronic ...
  • Digital Forensic Model for a Cloud Environment 
    Sibiya, Mhlupheki George (University of Pretoria, 2015)
    Cloud computing is a relatively new computing paradigm that builds upon virtualisation technologies to provide hardware, platforms and software as services over the Internet. The cloud can be deployed in four basic ...
  • An Analysis of Overfitting in Particle Swarm Optimised Neural Networks 
    van Wyk, Andrich Benjamin (University of Pretoria, 2014)
    The phenomenon of overfitting, where a feed-forward neural network (FFNN) over trains on training data at the cost of generalisation accuracy is known to be speci c to the training algorithm used. This study investigates ...
  • Touch Biometrics for Unobtrusive Continuous Authentication on Smartphones 
    Kroeze, Christina J. (University of Pretoria, 2015)
    Mobile devices such as smartphones have until now been protected by traditional authentication methods, including passwords or PINs. These authentication mechanisms are di cult to remember and often disabled, leaving the ...
  • Evaluating a Semantic Approach to Address Data Interoperability 
    Tewolde, Noh Teamrat (University of Pretoria, 2014)
    Semantic approaches have been used to facilitate interoperability in different fields of study. Current literature, however, shows that the semantic approach has not been used to facilitate the interoperability of addresses ...
  • Using depth information to aid stereoscopic image forensics 
    Fouche, Mark-Anthony (University of Pretoria, 2014)
    With the advances in image manipulation software, it has become easier to manipulate digital images. These manipulations can be used to increase image quality, but can also be used to depict a scene that never occurred. ...
  • Digital Audio Restoration of Gramophone Records 
    Stallmann, Christoph Frank (University of Pretoria, 2015)
    Gramophones were the main audio recording medium for more than seven decades and regained widespread popularity over the past few years. Being an analogue storage medium, gramophone records are subject to distortions caused ...
  • Digital Forensics in Second Life 
    Rakitianskaia, A.S. (Anastassia Sergeevna) (University of Pretoria, 2015)
    Computers and the internet have become an integral part of our lives. People have grown accustomed to feeling constantly connected to the outside world, and in the past couple of decades online social networks and ...
  • A Computational Intelligence Approach to Clustering of Temporal Data 
    Georgieva, Kristina Slavomirova (University of Pretoria, 2015)
    Temporal data is common in real-world datasets. Analysis of such data, for example by means of clustering algorithms, can be difficult due to its dynamic behaviour. There are various types of changes that may occur to ...
  • Reconstruction in Database Forensics 
    Adedayo, Oluwasola Mary (University of Pretoria, 2015)
    The increasing usage of databases in the storage of critical and sensitive information in many organizations has led to an increase in the rate at which databases are exploited in computer crimes. Databases are often ...
  • Design of a hybrid command and control mobile botnet 
    Pieterse, Heloise (University of Pretoria, 2014)
    Mobile devices have excelled in the 21st century due to the increasing popularity and continuous improvement of mobile technology. Today mobile devices have become all-in-one portable devices, providing inter-connectivity, ...
  • Automated usability analysis and visualisation of eye tracking data 
    De Bruin, Jhani Adre (University of Pretoria, 2014)
    Usability is a critical aspect of the success of any application. It can be the deciding factor for which an application is chosen and can have a dramatic effect on the productivity of users. Eye tracking has been ...
  • An investigation into the consistency and usability of selected minisatellite detecting software packages 
    Masombuka, Koos Themba (University of Pretoria, 2013)
    A tandem repeat is a sequence of adjacent repetitions of a nucleotide patternsignature, called its motif, in a DNA sequence. The repetitions may either be exact or approximate copies of the motif. A minisatellite is a ...
  • A Chain of findings for digital investigations 
    De Souza, Pedro (University of Pretoria, 2013)
    Digital Forensic investigations play a vital role in our technologically enhanced world, and it may incorporate a number of different types of evidence — ranging from digital to physical. During a Digital Forensics ...
  • Characterising continuous optimisation problems for particle swarm optimisation performance prediction 
    Malan, Katherine Mary (University of Pretoria, 2014)
    Real-world optimisation problems are often very complex. Population-based metaheuristics, such as evolutionary algorithms and particle swarm optimisation (PSO) algorithms, have been successful in solving many of these ...
