  • Representing chemical structures using OWL and description graphs 
    Hastings, Joanna Kathleen (2010-11)
    Objects can be said to be structured when their representation also contains their parts. While OWL in general can describe structured objects, description graphs are a recent, decidable extension to OWL which support ...
  • Representing quadrics on a computer 
    Coetzee, MA; Baart, ML (2000)
    In our research on transfinite interpolation with quadric patches, we needed to draw the part of some quadratic surface that lies between two given planes. In this talk, we discuss a way to parameterize a quadric patch ...
  • Requirements for an eModeration System in Private Schools in South Africa 
    Rajamany, Vanitha; Van Staden, Corne Johandia; Van Biljon, Judy (Springer Nature Switzerland AG, 2020)
    Despite the growing importance of digitization in all aspects of teaching and learning, digital moderation (eModeration) has received little attention in research or practice. Considering the secondary school environment, no ...
  • Research collaboration in asymmetric power relations: A study of postgraduate students’ views 
    Van Biljon, Judy; Mwapwele, Samwel (AOSIS, 2023-02-16)
    Collaboration among researchers and across disciplinary, organisational and cultural boundaries is essential for addressing the increasingly complex challenges and opportunities facing international development. Despite ...
  • Research computeracy 
    Pirow, Peter Cluver (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    This paper describes the concept of computeracy as it applies to research workers and argues that research will be improved if the level of computeracy can be raised.
  • Research directions in information systems 
    Mende, J. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    The success of a research project depends upon the inputs and outputs selected by the researcher, a poor choice entailing useless results or wasted efforts.To avoid this one might consider the following alternatives: t. ...
  • Research in information technology at South Africans Technikons 
    Von Solms, R (1995)
    Traditionally, Technikon training was focused on career-oriented education and training. This has changed over the last few years and research has started to play a major role in Technikon education. This additional objective ...
  • Research on Mobile Cloud Computing in Teaching and Learning: A Conceptual Model 
    Van Biljon, Judy; Van der Merwe, Ronell (Academic Conferences and Publishing International Limited, 2018)
    Advances in cloud computing technology coupled with increasing volumes of data has driven the growth and differentiation of cloud-based solutions in teaching and learning. The cloud computing industry has matured over the ...
  • Research trends in the implementation of eModeration Systems: A Systematic Literature Review 
    Rajamany, Vanitha; Van Biljon, Judy; van Staden, Corne Johandia (Springer, 2021)
    The 2020 COVID-19 health pandemic has accelerated the trend towards digitizing education. Increased digitization necessitates a robust and regulatory framework for monitoring standards in a knowledge society, which ...
  • Researching the effects of culture on usability 
    Ford, Gabrielle (2005-01)
    An experiment was conducted to determine the effects of subjective culture on the usability of computerized systems. The results of the experiment did not provide sufficient evidence to conclude that any of the tested ...
  • Response surface analysis as a technique for the visualization of linear models and data 
    Terblanche, F; Hattingh, G (1998)
    Response surface analysis aims of exploring the behavior of a response function in some region. Some authors (see e.g. [BRU] and [DEV]), have used this approach to get "better" interpretations of the behavior of linear ...
  • Restructuring of the Conceptual Schema to produce DBMS Schemata 
    Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    An overall methodology for database design is presented. This includes creation of a data dictionary and relational analysis. An algorithm is presented to create a conceptual schema or logical database design from the set ...
  • Rethinking IS Curricula for South Africa 
    Froneman, L; Roode, JD (1995)
