Individual-based computer models (IBM) feature prominently in current theoretical ecology but have only been applied in a small number of parasitological studies. Here we designed an IBM to simulate the infection dynamics of gyrodactylid parasites an...

Steering via the image in local, distributed and collaborative settings (2007)
Presentation / Conference Contribution
Wright, H., & Wood, J. D. Steering via the image in local, distributed and collaborative settings

Computational steering is a valuable mechanism for scientific investigation in which the parameters of a running program can be altered and the results visualized immediately. In a previous paper we put forward an architecture for computational steer... Read More about Steering via the image in local, distributed and collaborative settings.

In this paper, we present a new set of blending operations for implicitly defined geometric shapes. The proposed shape operators are piecewise polynomial and blending range controllable, and can be constructed to any required degree of smoothness. Th...

Classical Fault Tree Analysis (FTA) can determine the effects of combinations of failure events on a system but cannot capture the significance of the temporal order of events, which may be critical. In this paper, we propose an extension based on fo... Read More about Synthesis and analysis of temporal fault trees with PANDORA: the time of Priority AND gates.

Immersive visualization with automated collision detection for radiotherapy treatment planning (2007)
Journal Article

Intensity modulated radiotherapy (IMRT) is a technique for treating cancer tumours using external delivery of radiation. To create a treatment plan the directions of the external radiation beams (typically 5 to 9) need to be specified. Normally the b...

Radiotherapy training tools for yesterday’s future (2007)
Book Chapter
(2007). Radiotherapy training tools for yesterday’s future. In Imaging and Oncology (30 - 35). Deeson Group

Radiotherapy techniques have evolved rapidly in recent years. However, the uptake and clinical implementation of novel techniques, such as intensity modulated radiotherapy (IMRT), was slower than was initially anticipated. One of the reasons often gi...

Face recognition in pictures is affected by perspective transformation but not by the centre of projection (2006)

Recognition of unfamiliar faces is susceptible to image differences caused by angular sizes subtended from the face to the camera. Research on perception of cubes suggests that apparent distortions of a shape due to large camera angle are correctable...
