  • A visual modelling technique for controlling graph transformations 
    Gruner, Stefan; Kurt, Murat; Taentzer, Gabriele (Carleton Scientific, 2000)
    Sophisticated control concepts are necessary to make the application of graph grammars feasible for practical graph grammar engineering and specification tasks. For this purpose we introduce hybrid control graphs based on ...
  • Visualising basins of attraction for the cross-entropy and the squared error neural network loss functions 
    Bosman, Anna Sergeevna; Engelbrecht, Andries; Helbig, Marde (Elsevier, 2020-08)
    Quantification of the stationary points and the associated basins of attraction of neural network loss surfaces is an important step towards a better understanding of neural network loss surfaces at large. This work proposes ...
  • Weak factor automata : the failure of failure factor oracles? 
    Cleophas, L.G.W.A. (Loek); Kourie, Derrick G.; Watson, Bruce William (Computer Society of South Africa, 2014-08)
    In indexing of, and pattern matching on, DNA and text sequences, it is often important to represent all factors of a sequence. One e cient, compact representation is the factor oracle (FO). At the same time, any classical ...
  • Web services access control architecture incorporating trust 
    Coetzee, Marijke; Eloff, Jan H.P. (Emerald, 2007)
    PURPOSE – This paper seeks to investigate how the concept of a trust level is used in the access control policy of a web services provider in conjunction with the attributes of users. DESIGN/METHODOLOGY/APPROACH – A ...
  • A web-based mouse dynamics visualization tool for user attribution in digital forensic readiness 
    Ernsberger, Dominik; Adeyemi, Ikuesan Richard; Venter, H.S. (Hein); Zugenmaier, Alf (Springer, 2018-01)
    The Integration of mouse dynamics in user authentication and authorization has gained wider research attention in the security domain, specifically for user identification. However, same cannot be said for user identification ...
  • What is an address in South Africa? 
    Coetzee, Serena Martha; Cooper, Antony Kyle; Adam, John B. (AOSIS Open Journals, 2007-11)
    Addresses come in many forms as they have a variety of uses. In our paper we illustrate the need for standardized addresses in South Africa by describing scenarios where standardized addresses are required, or where ...
  • Which are harder? Soft skills or hard skills? 
    Pieterse, Vreda; Van Eekelen, Marko (Springer, 2016-10)
    This paper describes some technical and employability skills that are essential for our students to succeed in a career in software development. We conducted research aimed at understanding the students' problems when ...
  • Why is this an anomaly? Explaining anomalies using sequential explanations 
    Mokoena, Tshepiso; Celik, Turgay; Marivate, Vukosi (Elsevier, 2022-01)
    In most applications, anomaly detection operates in an unsupervised mode by looking for outliers hoping that they are anomalies. Unfortunately, most anomaly detectors do not come with explanations about which features make ...
  • Wind farm layout design using cuckoo search algorithm 
    Rehman, S.; Ali, S.S.; Khan, Salman Ahmad (Taylor and Francis, 2018)
    Wind energy has emerged as a strong alternative to fossil fuels for power generation. To generate this energy, wind turbines are placed in a wind farm. The extraction of maximum energy from these wind farms requires optimal ...
  • Windows registry harnesser for incident response and digital forensic analysis 
    Singh, Avinash; Venter, H.S. (Hein); Ikuesan, Adeyemi Richard (Taylor and Francis, 2020)
    The extraction of digital evidence from storage media is a growing concern in digital forensics, due to the time and space complexity in acquiring, preserving and analysing digital evidence. Microsoft Windows Registry is ...
