Improving and still passing the ALife test: Component-normalised activity statistics classify evolution in Geb as unbounded (2003)
Book Chapter
Channon. (2003). Improving and still passing the ALife test: Component-normalised activity statistics classify evolution in Geb as unbounded. In Artificial Life VIII: proceedings of the Eighth International Conference on Artificial Life (173 -181)

Bedau, Snyder & Packard’s (1998) classification system for long-term evolutionary dynamics provides a test for openended evolution. Making this ALife test more rigorous, and passing it, are two of the most important open problems in the field. Previo...

Connectionist learning of regular graph grammars (2001)
Journal Article
Fletcher. (2001). Connectionist learning of regular graph grammars. Connection science, 127 - 188. https://doi.org/10.1080/09540090110072327

This paper presents a new connectionist approach to grammatical inference. Using only positive examples, the algorithm learns regular graph grammars, representing two-dimensional iterative structures drawn on a discrete Cartesian grid. This work is i...

Ceramic fuel cells to replace metal burners (2001)
Journal Article
Kendall, K., Finnerty, C., Austin, J., & Alston, T. (2001). Ceramic fuel cells to replace metal burners. Journal of Materials Science, 36, 1119–1124. https://doi.org/10.1023/A%3A1004869522984

Global warming is thought to result from emissions largely caused by combustion reactions. Designs of burners and specifications of their materials are therefore of primary importance in restraining the warming phenomena. This paper proposes a new ty...

Towards the evolutionary emergence of increasingly complex advantageous behaviours (2000)
Journal Article
Channon. (2000). Towards the evolutionary emergence of increasingly complex advantageous behaviours. International Journal of Systems Science, 843 -860. https://doi.org/10.1080/002077200406570

The generation of complex entities with advantageous behaviours beyond our manual design capability requires long-term incremental evolution with continuing emergence. In this paper, we argue that artificial selection models, such as traditional gene... Read More about Towards the evolutionary emergence of increasingly complex advantageous behaviours.

Thefractal dimension of kaolin flocs suspended in water was increased by the addition of potassium chloride and indirectly monitored by low-power ultrasonic pulses in a test cell with a “pitch-catch” configuration. The results from these measurements... Read More about The detection of structural transformations in kaolin suspensions by ultrasound.

Ultrasonic propagation through aqueous kaolin suspensions during degassing (1999)
Journal Article

A degassing procedure is necessary prior to taking ultrasonic measurements in aqueous kaolin suspensions as well as many other liquid based colloids. In this work we compare two degassing methods and show that subjecting a sample to a power ultrasoun... Read More about Ultrasonic propagation through aqueous kaolin suspensions during degassing.

(1999). Buckling of an elastic half-space with surface imperfections. In 1st Canadian Conference on Nonlinear Solid Mechanics: CanCNSM, Victoria, British Columbia, Canada, June 16-June 20, 1999 (99 -107)

Over the years, linear analysis of the stability of pre-stressed elastic half-spaces has been carried out for various kinds of materials and various forms of pre-stress; see Biot (1965), Nowinski (1969a, b), Willson (1973a, b), Usmani \& Beatty (1974...
