  • Two conjectures on 3-domination critical graphs 
    Moodley, Lohini (1999-01)
    For a graph G = (V (G), E (G)), a set S ~ V (G) dominates G if each vertex in V (G) \S is adjacent to a vertex in S. The domination number I (G) (independent domination number i (G)) of G is the minimum cardinality ...
  • Ubiquitous computing and cellular handset interfaces - are menus the best way forward?

  • Understanding the joint effect of the behavioural and biological risk reduction factors on HIV 
    Gundidza, Patricia Tapiwa (2021-10-01)
    The conventional approach in determining HIV risk factors fails to consider the influence behavioural and biological factors may have when modelled jointly. This study investigates the extent of influence behavioural and ...
  • Universal homophonic coding 
    Stevens, Charles Cater (1996-11)
    Redundancy in plaintext is a fertile source of attack in any encryption system. Compression before encryption reduces the redundancy in the plaintext, but this does not make a cipher more secure. The cipher text is still ...
  • The universal relation as a database interface 
    Philips, M.J.; Berman, Sonia (South African Institute of Computer Scientists and Information Technologists, 1991)
    The universal relation is a way of overcoming users' prime database access difficulty, namely navigation through database structures. As a result there is reduced user involvement with the underlying logical database ...
