The Symmetrical List Processor SLIP; developed by Professor Joseph Weizenbaum of MIT, was implemented with considerable modifications and additions on the University of Cape Town computer. A package to perform automated ...

Marsaglia and Maclaren combined two linear congruential generators in order to produce a pseudo random number sequence uniformly distributed in the range [0,2³⁵]. Their method is a considerable improvement compared with ...

The thesis describes the design and implementation of a PL/I subset compiler which produces a hypothetical stack code as output. The compiler was based on a Pascal compiler developed by N. Wirth and U. Amman of Eidgenössische ...

The thesis describes the design and implementation of a simulation model. The model is patterned after the EXEC-8 multiprogramming time sharing operating system on the UNIVAC 1106 computer at the computer centre of the ...

An integrated payroll-pension system designed specifically for commercial users with limited computer resources is presented. This system combines in a single system the usual functions of both a payroll system and a pension ...

Three of the branches of image processing are touched upon herein: image capture, enhancement and display. Image capture here means 'the making available of an image for further processes to be carried out on it'. This is ...

Since the emergence of the digital computer in the 1940s, computer architecture has been largely dictated by the requirements of mathematicians and scientists. Trends have thus been towards processing data as quickly and ...

The use of computer technology and magnetic storage media for production typing led to a new term "word processing". In this research word processing is considered to be part only of a more comprehensive concept - electronic ...

A very-high-level data manipulation language for a database system is one in which the user specifies in non-procedural terms the operations that are to be performed on the data stored in the database; the actual method ...

The development of software for data processing systems has, during the last 25 years, grown into a large industry. Thus the efficiency of the software development process is of major importance. It is indicative of the ...

The automatic database design system is a design aid for network database creation. It obtains a requirements specification from a user and generates a prototype database. This database is compatible with the Data Definition ...

ADA is a high level programing language sponsored by the United States Department of Defence primarily for use in real-time systems. It has all the structures present in modern algorithmic languages with additional features ...

A graphical language is developed as a generalization of the structured flowcharts proposed by Nessi and Shneiderman. This language can be used in the specification of procedures, procedure interfaces and data structures. ...

Context conditions - also called static semantics - are the constraints on computer programs that cannot be reasonably expressed by a context-free grammar, but that can be statically checked without considering the execution ...

This thesis discusses the University of Cape Town implementation of a table driven back end processor. The back end processor takes as input an intermediate tree representation of a high level programming language. It ...

The design and implementation of a method to software interface high level applications programs used for the control and monitoring of a Particle Accelerator is described. Effective methods of interfacing the instrumentation ...

This thesis concentrates on several important issues in expert system research, namely - representation of knowledge - control of reasoning - implementation of non-monotonic logics via truth maintenance systems. There are ...

The increasing development and use of computer networks has necessitated international standards to be defined. Central to the standardization efforts is the concept of a Formal Description Technique (FDT) which is used ...

The DISTRIX operating system is a multiprocessor distributed operating system based on UNIX. It consists of a number of satellite processors connected to central servers. The system is derived from the MINIX operating ...

Two technologies, distributed operating systems and UNIX are very relevant in computing today. Many distributed systems have been produced and many are under development. To a large extent, distributed systems are considered ...
