In today's highly competitive global economy, information resources representing enterprise-wide information are essential to the survival of an organization. The development of and increase in the use of personal computers and data communication networks are supporting or, in many cases, replacing the traditional computer mainstay of corporations. The client/server model incorporates mainframe programming with desktop applications on personal computers. The aim of the research is to compile a technology model for the development of client/server software. A comprehensive overview of the individual components of the client/server system is given. The different methodologies, tools and techniques that can be used are reviewed, as well as client/server-specific design issues. The research is intended to create a road map in the form of a Technology Reference Model for Client/Server Software Development. / Computing / M. Sc. (Information Systems)

Computers have become indispensable in all walks of life, causing people to rely increasingly on their accurate performance. Defective computer programs, the incorrect use of computer programs and the non-use of computer programs can cause serious damage. Expert systems are an application of artificial intelligence techniques whereby the human reasoning process is simulated in a computer system, enabling the system to act as a human expert when executing a task. Expert systems are used by professional users as an aid in reaching a decision and by nonprofessional users to solve a problem or to decide upon a specific course of action. As such they can be compared to a consumer product through which professional services are sold. The various parties that may possibly be held liable in the event of damage suffered by the use of expert systems are identified as consisting of two main groups, namely the producers and the users. Because of the frequent exemption of liability for any consequential loss in standard form computer contracts, the injured user may often have only a delictual action at her disposal. The faultbased delictual actions in SA law give inadequate protection to unsuspecting software users who incur ·personal and property damage through the use of defective expert systems since it is almost impossible for an unsophisticated injured party to prove the negligence of the software developer during the technical production process. For this reason it is recommended that software liability be grounded on strict liability in analogy to the European Directive on Liability for Defective Products. It is also pointed out that software standards and quality assurance procedures have a major role to play in the determination of the elements of wrongfulness and negligence in software liability and that the software industry should be accorded professional status to ensure a safe standard of computer programming. / Private Law / LL.D.

The focus of the dissertation is on software quality assurance for object-oriented information systems development. A Quality Assurance Reference Model is proposed with aspects dealing with technical and managerial issues. A revised Spiral life cycle model is adopted as well as the Object Modelling Technique. The Quality Assurance Reference Model associates quality factors at various levels, quality criteria and metrics into a matrix framework that may be used to achieve quality assurance for all cycles of the Spiral Model. / Computing / M.

Práce se zabývá návrhem automobilové elektronické řídicí jednotky (ECU) s funkcí partial networking definovanou normou ISO 11898-6. Cílem je navrhnout a vytvořit demonstrační ECU s použitím system basis chip NCV7471. Protože NCV7471 obsahuje standardní CAN transceiver, funkce partial networking je realizována pouze softwarem řídicí jednotky. Práce zvažuje možné způsoby realizace jak HW, tak SW části, tak aby byla zajištěna nízká spotřeba ECU v různých operačních módech, a snaží se sledovat současné trendy v automobilovém průmyslu.
