Implementation of the Fletcher-Reeves optimization strategy into the GOSPEL optimization package is examined. An explanation of the GOSPEL package is provided, followed by the presentation of the Fletcher-Reeves strategy. Performance of all strategies in the updated GOSPEL package are compared for nine test cases. A user manual for GOSPEL operation as well as the source code are also included.

Thesis (MSc)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: Users are not supposed to modify an operating system kernel, but it is often necessary to add a device driver for a new peripheral device. Device driver development is a difficult and time-consuming process that must be performed by an expert. Drivers are difficult to debug and a malfunctioning driver could cause the operating system to crash. Ways are therefore needed to make the development of device drivers safer and easier. A number of different device driver development methods are examined in this thesis. An existing micro-kernel that supports in-kernel device drivers as well as extensible device drivers has been modified to support user-level and loadable drivers. These extensions ensured that all the development methods were implemented in the same environment and a comparison could thus be made on a fair basis. A comparison of the different methods with respect to the efficiency of the resulting device driver, as well as the ease of the development process, is presented. / AFRIKAANSE OPSOMMING: Gebruikers is nie veronderstelom aan 'n bedryfstelsel te verander nie, maar tog is dit gereeld nodig om 'n toesteldrywer vir 'n nuwe randapparaat by te voeg. Die ontwikkeling van 'n toesteldrywer is 'n tydrowende en moeilike proses en moet deur 'n kundige aangepak word. Toesteldrywers is moeilik om te ontfout en kan deur verkeerde werking die hele stelsel tot stilstand bring. Daar is dus tegnieke nodig om die ontwikkeling van toestelhanteerders makliker en veiliger te maak. 'n Aantal verskillende ontwikkelingsmetodes vir toesteldrywers word in hierdie tesis ondersoek. 'n Bestaande mikro-kern wat in-kern, sowel as uitbreibare toesteldrywers ondersteun, is aangepas om gebruikersvlak en laaibare toestelhanteerders te ondersteun. Hierdie uitbreiding het verseker dat al die ontwikkelingsmetodes in dieselfde omgewing geïmplementeer is. Dit was dus moontlik om die metodes op 'n regverdige grondslag te vergelyk. Die vergelyking is gedoen ten opsigte van die effektiwiteit van die resulterende toesteldrywer sowel as die moeilikheidsgraad van die ontwikkelingsproses.

Thesis (MBA)--Stellenbosch University, 1988. / INTRODUCTION: The object of this technical report is to enhance an already existing computer program which calculates the possible growth rate under certain given conditions. These enhancements would make the program more applicable to a variety of situations and possibly a more true indication of what would happen in real life. The existing program was initially written in the FORTRAN-77 language by J C d Bruin in 1982 and translated to the TRUE BASIC language in 1985. The main objective of the program is to determine the maximum growth % of a business subject to certain given parameters or constraints.
