(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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, ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(University of Pretoria, 2018)This thesis compares the profitability of trading rules evolved by a single population genetic program (GP), a co-operative co-evolved GP, and a competitive co-evolved GP. Profitability was determined by trading thirteen ...
-
(University of Pretoria, 2016)Computational science is a practice that requires a large amount of computing time. One means of providing the required computing time is to construct a distributed computing system that utilises the ordinary desktop ...
-
(University of Pretoria, 2017)Email forensic investigations rely on the collection and analysis of digital forensic evidence collected from email systems. Problems arise when the digital forensic evidence needed for the email forensic investigation is ...
-
(University of Pretoria, 2018)The cloud has exacerbated the difficulty of digital forensic investigations because data may be spread over an ever-changing set of hosts and data centers. The normal search and seizure approach digital forensic investigators ...
-
(University of Pretoria, 2017)Particle swarm optimisation (PSO) is a stochastic, population-based optimisation algorithm. PSO has been applied successfully to a variety of domains. This thesis examines the behaviour of PSO when applied to high dimensional ...
-
(University of Pretoria, 2017)The ubiquity of the cloud has accelerated an abundance of modern Information and Communication Technology (ICT)-based technologies to be built based on the cloud infrastructures. This has increased the number of internet ...
-
(University of Pretoria, 2018-07)The particle swarm optimization (PSO) algorithm is a stochastic, population-based optimization technique influenced by social dynamics. It has been shown that the performance of the PSO algorithm can be greatly improved ...
-
(University of Pretoria, 2018-04)In the thesis of “Mohammed Aijaz Mohiuddin”, Engineering Nature-Inspired Heuristics for the Open Shortest Path First Weight Setting Problem, nature inspired heuristics were developed. Besides the existing two objectives, ...
-
(University of Pretoria, 2017)An exploratory analysis in low-dimensional objective space of the vector evaluated particle swarm optimization (VEPSO) algorithm is presented. A novel visualization technique is presented and applied to perform the exploratory ...
