There is no accepted standard for the object-oriented database paradigm at present, which has led to different definitions of features and conformance requirements. HOOD is a Higher-Order Object-Oriented Database system ...

Digital rights management (DRM) can be defined as a technology that enables persistent access control. The common understanding of DRM is that of a technology that enables means to thwart piracy of digital multimedia through ...

Office automation systems have become an essential tool for the operation of the modern office. With the emphasis of a modern office being placed on efficiency and ease of communication, office automation systems have ...

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 ...

Persistence is measured by the length of time an object is retained and is usable in a system. Persistent languages extend general purpose languages by providing the full range of persistence for data of any type. Moreover, ...

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 ...

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 ...

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 ...

Although learning management systems (LMSs) have been widely adopted by universities in developing countries, their potential to support students' learning has not been fully exploited due to several factors. Some of the ...

There exist several challenges in supporting mobile applications. For example, creating a separate target application for each device type, leaving developers with a huge maintenance chore. Most desktop applications run ...

The ubiquity of mobile phones provides an opportunity to use them for learning programming beyond the classroom. This would be particularly useful for novice learners of programming in resource- constrained environments. ...

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 ...

There are many industries that have long been utilizing Geographical Information Systems (GIS) for spatial analysis. In many parts of the world, it has gained less popularity because of inaccurate geocoding methods and a ...

The performance analysis of parallel programs is a complex task, particularly if the program has to be efficient over a wide range of parallel machines. We have designed a performance analysis system called Chiron that ...

The research has been based on the thesis that efficient volume rendering of datasets, contained on the Internet, can be achieved on average personal workstations. We present a new algorithm here for efficient incremental ...

This dissertation concerns the specification and description of complex communicating systems using Formal Description Techniques. Specifically, we propose a standard graphical representation for the Formal Description ...

This study investigates the complexity of various reduction and synthesis Petri net transformations. Transformations that preserve liveness and boundedness are considered. Liveness and boundedness are possibly the two most ...

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 ...

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 ...

Software engineers have identified many problem areas regarding the development of software. There is a need for improving system and program quality at design level, ensuring that design costs remain within the budget, ...
