  • Software testing in small IT companies : a (not only) South African problem 
    Gruner, Stefan (Computer Society of South Africa, 2011-07)
    Small software companies make for the majority of software companies around the world, but their software development processes are often not as clearly de ned and structured as in their larger counterparts. Especially the ...
  • The South African Computer Journal : 1989 to 2010 
    Kourie, Derrick G. (Royal Society of South Africa, 2010-06)
    The South African Computer Journal (SACJ), as the successor of the Quæstiones Informaticæ journal founded by Derek Henderson, is part of his heritage to South Africa. This brief historical sketch of SACJ outlines the ...
  • Stability analysis of the multi-objective multi-guided particle swarm optimizer 
    Cleghorn, Christopher Wesley; Scheepers, Christiaan; Engelbrecht, Andries P. (Springer, 2018-10)
    At present particle swarm optimizers (PSO) designed for multi-objective optimization have undergone no form of theoretical stability analysis. This paper derives the sufficient and necessary conditions for order-1 and ...
  • A study of bi-space search for solving the one-dimensional bin packing problem 
    Beckedahl, Derrick; Pillay, Nelishia (Springer, 2020-10)
    Traditionally search techniques explore a single space to solve the problem at hand. This paper investigates performing search across more than one space which we refer to as bi-space search. As a proof of concept we ...
  • A survey of techniques for characterising fitness landscapes and some possible ways forward 
    Malan, Katherine Mary; Engelbrecht, Andries P. (Elsevier, 2013-08)
    Real-world optimisation problems are often very complex. Metaheuristics have been successful in solving many of these problems, but the difficulty in choosing the best approach can be a huge challenge for practitioners. ...
  • Taxonomy of challenges for digital forensics 
    Karie, Nickson M.; Venter, H.S. (Hein) (Wiley, 2015-07)
    Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital ...
  • Team trails, trials and tribulations - rigorously reckoning with requirements 
    Pieterse, Vreda; Du Toit, Cecilia Magdalena (Unisa Press, 2008)
    A major challenge to the efficacy of student team learning projects occurs when some members of a group are unable to contribute effectively to the collaborative endeavour due to their academic deficits. A graded benchmark ...
  • Technology-enhanced learning, data sharing, and machine learning challenges in South African education 
    Combrink, Herkulaas MvE; Marivate, Vukosi; Masikisiki, Baphumelele (MDPI, 2023-04-24)
    The objective of this paper was to scope the challenges associated with data-sharing governance for machine learning applications in education research (MLER) within the South African context. Machine learning applications ...
  • Text-line extraction from handwritten document images using GAN 
    Kundu, Soumyadeep; Paul, Sayantan; Bera, Suman Kumar; Abraham, Ajith; Sarkar, Ram (Elsevier, 2020-02)
    Text-line extraction (TLE) from unconstrained handwritten document images is still considered an open research problem. Literature survey reveals that use of various rule-based methods is commonplace in this regard. But ...
  • Three-valued bounded model checking with cause-guided abstraction refinement 
    Timm, Nils; Gruner, Stefan (Elsevier, 2019-04)
    We present a technique for verifying concurrent software systems via SAT-based three-valued bounded model checking. It is based on a direct transfer of the system to be analysed and a temporal logic property into a ...
  • Time series forecasting using neural networks : are recurrent connections necessary? 
    Abdulkarim, Salihu Aish; Engelbrecht, Andries P. (Springer, 2019-12)
    Artificial neural networks (NNs) are widely used in modeling and forecasting time series. Since most practical time series are non-stationary, NN forecasters are often implemented using recurrent/delayed connections to ...
  • A tool for interactive visualization of distributed algorithms 
    Gruner, Stefan; Mosbah, Mohamed; Bauderon, Michel (2001)
    We present a tool for the visualization of distributed computations. Special attention is payed to certain distributed algorithms which have been coded as rewriting systems. In order to study the behaviour of algorithms ...
  • Toward a general ontology for digital forensic disciplines 
    Karie, Nickson M.; Venter, H.S. (Hein) (Wiley-Blackwell, 2014-09)
    Ontologies are widely used in different disciplines as a technique for representing and reasoning about domain knowledge. However, despite the widespread ontology-related research activities and applications in different ...
  • Toward the visual understanding of computing curricula 
    Takada, Shingo; Cuadros-Vargas, Ernesto; Impagliazzo, John; Gordon, Steven; Marshall, Linda; Topi, Heikki; Van der Veer, Gerrit; Waguespack, Leslie (Springer, 2020-09)
    Various computing subdisciplines, such as computer science and software engineering, each have their own curricular guidelines. They can be very difficult to understand and compare for people such as prospective students, ...
  • Towards a digital policing in developing nations : the Nigerian context 
    Ismaila, Idris.; Legbo, Victor Y.; Ikuesan, Adeyemi Richard; Imavah, Shaka A.; Mohammad, Abdullahi B.; Abduldayan, Fatimah J.; Baba, Meshach. (Blue Eyes Intelligence Engineering and Sciences Publication, 2019-05)
