    The DISTRIX operating system is a multiprocessor UNIX-like distributed operating system. It consists of a number of satellite processors connected to central servers. The system is based on the MINIX operating system, ...
  • Hing, RL (South African Institute of Computer Scientists and Information Technologists, 1990)
    An old approach used in classification systems has been revived by the discovery of new algorithms which use this approach to approximate complex non-linear functions. This approach, known as neurocomputing, classifies ...
  • Heidema, J; Labuschagne, WA (South African Institute of Computer Scientists and Information Technologists, 1990)
    The theory of semantic information is sketched in an algebraic setting, and automorphisms characterising various degrees of incompatibility are introduced. Data-dependent measures of semantic information are defined in ...
