Incremental volume rendering using hierarchical compression
(1996)
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 ...
A graphical representation for the formal description technique Estelle
(1998)
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 ...
SSDE : structured software development environment
(1990)
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, ...
The complexity of Petri net transformations
(1993)
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 ...
A distributed computing environment (DCE) based object request broker
(1996)
Object oriented technology has moved beyond being a tool for design and programming and is now being used to implement enterprise wide computer systems. Also, there has been a move from centralised mainframe systems to ...
An object-oriented library for shared-memory parallel simulations
(1996)
Programming shared-memory multiprocessor systems is becoming increasingly difficult as the gap between memory speed and processor speed increases. At the same time, this class of computer-based on standard microprocessors-is ...
An extension to optic flow analysis for the generation of computer animated images
(1998)
This dissertation seeks to develop image based animation methods using the technique of optic flow analysis developed for a moving planar object. Image based rendering is presented as a class of algorithm using two dimensional ...
Visually querying object-oriented databases
(1997)
As database requirements increase, the ability to construct database queries efficiently becomes more important. The traditional means of querying a database is to write a textual query, such as writing in SQL to query a ...
Exploiting persistence in CASE technology
(1997)
A Design Workbench has been built for Napier88 [MBC+94] as part of the natural progression towards developing better product systems and improving software construction tools. The system includes a Metamodeller (enabling ...
Distributed shared memory for virtual environments
(1997)
This work investigated making virtual environments easier to program, by designing a suitable distributed shared memory system. To be usable, the system must keep latency to a minimum, as virtual environments are very ...
