M.Com. (Computer Auditing) / The implementation of EDI into South Africa business has only started in the recent past. The main reason for this is the fact that the huge benefits in terms of faster processing of business transactions, reduced costs of processing and the formation of strategic business alliances with key business partners, is only now being accepted by management. The other reason is due to the fact that large, commercially operated Value Added Networks (VANs) have only been in existence in this country during the last two years. The primary objective of this short dissertation can be summarised as follows: a) To provide a brief overview of the developments which are currently taking place in South Africa in the Electronic Data Interchange (EDI) environment and the Value Added Network (VAN) environment; b) To highlight how EDI is currently being implemented in South Africa; c) To develop a simplistic framework of key information systems controls which an auditor should consider when evaluating the information systems at a client; and d) To apply this controls framework to the EDI and VAN environments in order to derive lists of the information systems controls which should be reviewed by the auditor when their client makes use of an EDI VAN.

A microscope was interfaced to a PDP-9 computer in order to develop techniques suitable for on-line classification of white blood cells. The computer visual-input system is composed of an image dissector optically coupled to a microscope used in a transmitted light mode. The position of the slide under the microscope and the fine focus control are controllable from the computer. A technique of auto-focusing was developed to efficiently focus the microscope under computer control. This algorithm is described in detail, followed by a discussion of the physical factors that affect the performance of this technique. A method of locating or isolating the leukocytes (white blood cells) is described next. A constant, referred to as the "contrast ratio' is used to extract the threshold for the nuclei of the leukocytes based on the average background intensity. Finally, contour tracing and curvature function extraction are used as a means of testing the system. A specific test is conducted to obtain a comparison of the system's efficiency as compared to that of "manual" techniques used by a technician. The system described here is not only suitable for automatic leukocyte classification, but could also be used for many other routine tests requiring the examination of microscopic cells. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
