  • Information and Communication Technology for Development (ICT4D) research: the quest for a shared conceptual framework continues 
    Van Biljon, Judy Alexander, Trish (In Proceedings of the 8th International Development Informatics Conference (IDIA2013), 2014)
    The Information and Communication for Development (ICT4D) research landscape can be described as a dynamic, fragmented adhocracy and hence, predictably, attempts at producing a shared conceptual framework for the field ...
  • Towards Increasing Supervision Capacity: The Pyramid Cohort Supervision Model 
    Van Biljon, Judy Van Dyk, Tobie Naidoo, Lizelle (Nelson Mandela Metropolitan University, 2014-06-25)

  • Risk management in software development 
    Labuschagne, Mariet (2000-01)
    This dissertation discusses risk management in the context of software development. It commences by investigating why so many software development projects fail. It then focuses on approaches to software development that ...
  • Products of diagonalizable matrices 
    Khoury, Maroun Clive (2002-09)
    Chapter 1 reviews better-known factorization theorems of a square matrix. For example, a square matrix over a field can be expressed as a product of two symmetric matrices; thus square matrices over real numbers can be ...
  • Temporal logics 
    Horne, Tertia (1999-09)
    We consider a number of temporal logics, some interval-based and some instant-based, and the choices that have to be made if we need to construct a computational framework for such a logic. We consider the axiomatisation ...
