  • Text Compression Techniques 
    Radue, J. E. (Computer Society of South Africa (on behalf of SAICSIT), 1979)
    The benefits associated with text compression include more efficient use of peripheral devices. faster information transfer rates and, in some cases, improved sorting speeds through the use of shorter sort keys. However. ...
  • The P-NP Question and Recent Independence Results 
    Philips, N.C.K. (Computer Society of South Africa (on behalf of SAICSIT), 1979)
    Despite intensive research the P = NP question is unresolved and the research suggests thatitis hard to answer. The corresponding question for query machines with recursive oracles is undecidable in set theory. Simply ...
  • A Hardware-Based Real-Time Operating System 
    Rodd, M. G. (Computer Society of South Africa (on behalf of SAICSIT), 1979)
    The efficient use of multiprogrammed industrial control computers is largely a function of the relationship between hardware and software. A shift in this relationship is desirable, since multiprogrammed computers typically ...
  • Real-Time Interactive Multiprogramming
