  • Adapting usage control as a deterrent to address the inadequacies of access controls 
    Padayachee, Keshnee; Eloff, Jan H.P. (Elsevier, 2009)
    Access controls are difficult to implement and evidently deficient under certain conditions. Traditional controls offer no protection for unclassified information, such as a telephone list of employees that is unrestricted, ...
  • Adding digital forensic readiness as a security component to the IoT domain 
    Kebande, Victor Rigworo; Karie, Nickson M.; Venter, H.S. (Hein) (Indonesian Society for Knowledge and Human Development, 2018)
    The unique identities of remote sensing, monitoring, self-actuating, self–adapting and self-configuring “things” in Internet of Things (IoT) has come out as fundamental building blocks for the development of “smart ...
  • Address databases for national SDI : comparing the novel data grid approach to data harvesting and federated databases 
    Coetzee, Serena Martha; Bishop, Judith (International Journal of Geographical Information Science, 2009-09-07)
    The original purpose of addresses was to enable the correct and unambiguous delivery of postal mail. The advent of computers and more specifically geographic information systems (GIS) opened up a whole new range of ...
  • An algorithm for mapping short reads to a dynamically changing genomic sequence 
    Iliopoulos, Costas S.; Kourie, Derrick G.; Mouchard, Laurent; Musombuka, Themba K.; Pissis, Solon P.; De Ridder, Corne (Elsevier, 2012-01)
    Next-generation sequencing technologies have redefined the way genome sequencing is performed. They are able to produce tens of millions of short sequences (reads), during a single experiment, and with a much lower cost ...
  • Analysing drivers’ preferences for privacy enhancing car-to-car communication systems : a study from South-Africa 
    Islami, Lejla; Fischer-Hubner, Simone; Hammond, Eunice Naa Korkoi; Eloff, Jan H.P. (Springer, 2021-04)
    While privacy-enhancing solutions for car-to-car communication are increasingly researched, end user aspects of such solutions have not been in the focus. In this paper, we present a qualitative study with 16 car drivers ...
  • An application of CNN to classify barchan dunes into asymmetry classes 
    Van der Merwe, Barend Jacobus; Pillay, Nelishia; Coetzee, Serena Martha (Elsevier, 2022-06)
    Barchan morphometric data have been used as proxies of meteorological and topographical data in environments where this data is lacking (such as other planetary bodies), gaining insights into barchan dune field dynamics ...
  • Application of deep reinforcement learning in asset liability management 
    Wekwete, Takura Asael; Kufakunesu, Rodwell; Van Zyl, A.J. (Gusti) (Elsevier, 2023-11)
    Asset Liability Management (ALM) is an essential risk management technique in Quantitative Finance and Actuarial Science. It aims to maximise a risk-taker’s ability to fulfil future liabilities. ALM is especially critical in ...
  • Application of the feature-detection rule to the negative selection algorithm 
    Poggiolini, Mario; Engelbrecht, Andries P. (Elsevier, 2013-08)
    The Negative Selection Algorithm developed by Forrest et al. was inspired by the way in which T-cell lymphocytes mature within the thymus before being released into the blood system. The mature T-cell lymphocytes exhibit ...
  • The architecture of a digital forensic readiness management system 
    Reddy, Kamil; Venter, H.S. (Hein) (Elsevier, 2013-02)
    A coordinated approach to digital forensic readiness (DFR) in a large organisation requires the management and monitoring of a wide variety of resources, both human and technical. The resources involved in DFR in large ...
  • Argitektuur vir die proaktiewe verkryging en analise van forensiese inligting in wolkstelsels 
    Ras, D.J.; Venter, H.S. (Hein) (AOSIS Open Journals, 2016)
    Cloud systems have to deal with massive amounts of distributed, volatile data which makes forensic investigations difficult. Using the NIST reference architecture, a system is devised to proactively capture forensic data ...
