Sensors for early warning of post-harvest spoilage in potato tubers (2002)
Presentation / Conference
de Lacy Costello, B., Ewen, R., Gunson, H., Ratcliffe, N. M., & Spencer-Phillips, P. T. (2002, November). Sensors for early warning of post-harvest spoilage in potato tubers. Presented at BCPC Conference 2002 - Pests and Diseases, Brighton, UK

Post-harvest spoilage of potato tubers results in approximately 9 million annual loss in the UK alone. In this paper, we report work completed with funding from the British Potato Council to develop an electronic sensor system (e-nose) to enable the...

Highly sensitive mixed oxide sensors for the detection of ethanol (2002)
Journal Article
de Lacy Costello, B., Ewen, R., Guernion, N., & Ratcliffe, N. M. (2002). Highly sensitive mixed oxide sensors for the detection of ethanol. Sensors and Actuators B: Chemical, 87(1), 207-210. https://doi.org/10.1016/S0925-4005%2802%2900220-4

Sensors consisting of mixtures of tin dioxide and zinc oxide powders in a range of proportions were constructed. Each mixture was applied to an electrode-bearing alumina substrate either as a paste, or by screen printing. The responses of these senso...

Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond (2002)
Journal Article
Adamatzky, A., & de Lacy Costello, B. (2002). Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond. Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 66(4), 6. https://doi.org/10.1103/PhysRevE.66.046112

We exploit the particulars of diffusive wave front interactions in certain types of two-reactant reaction-diffusion medium to construct a laboratory prototype of an XOR gate. In the design, the values of the logic variables are represented by the pre... Read More about Experimental logical gates in a reaction-diffusion medium: The XOR gate and beyond.

Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton (2002)
Journal Article
Adamatzky, A., & de Lacy Costello, B. (2002). Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton. Naturwissenschaften, 89(10), 474-478. https://doi.org/10.1007/s00114-002-0363-6

We offer a new approach to computing a shortest collision-free path in a space containing obstacles, using an experimental chemical processor, based on the Belousov-Zhabotinsky (BZ) reaction. The chemical processor was then coupled via optical links... Read More about Collision-free path planning in the Belousov-Zhabotinsky medium assisted by a cellular automaton.

Addressing policy objectives of traffic control using evolutionary algorithms (2002)
Presentation / Conference
Sha'Aban, J., Tomlinson, A., HEYDECKER, B., & Bull, L. (2002, September). Addressing policy objectives of traffic control using evolutionary algorithms. Paper presented at European Transport Conference 2002, Cambridge, UK

This paper presents preliminary results from an ongoing research project that is investigating traffic management and signal control of evolutionary algorithms that use machine learning. It describes the application of novel technologies of machine l... Read More about Addressing policy objectives of traffic control using evolutionary algorithms.

We have produced an experimental implementation of a massively-parallel reaction-diffusion processor which performs one of the most essential parts of shape recognition - construction of a skeleton. A skeleton is a unique, stable and invariant repres... Read More about Experimental reaction-diffusion pre-processor for shape recognition.

The synthesis of 3-octadecyl- and 3-docosylpyrrole, their polymerisation and incorporation into novel composite gas sensitive resistors (2002)
Journal Article

3-Octadecylpyrrole and the novel 3-docosylpyrrole were synthesised in high yields. These monomers were polymerised with various oxidising agents to produce a range of 3-octadecylpolypyrroles and 3-docosylpolypyrroles with different counter-ions. Thes...
