A methodology for railway track maintenance modelling using Plausible Petri nets (2018)
Presentation / Conference
Chiachio, M., Chiachio, J., Prescott, D., & Andrews, J. (2018, September). A methodology for railway track maintenance modelling using Plausible Petri nets. Paper presented at Probabilistic Safety Assessment and Management PSAM 14

This paper proposes a new mathematical methodology to model expert systems with the ability to sequentially learn from data. To this end, the Plausible Petri nets (PPNs) methodology, first developed in M. Chiachío et al. [Proceedings of the Future Te...

Electro-deoxidation of solid chromium oxide in molten chloride salts (2005)
Presentation / Conference
Gordo, E., Chen, G. Z., & Fray, D. J. (2005, February). Electro-deoxidation of solid chromium oxide in molten chloride salts. Paper presented at TMS Annual Meeting 2005, San Francisco, California, U.S.A

Chromium is industrially produced by aluminothermic reduction of Cr 2O3 or electrodeposition from the aqueous NH 4Cr(SO4)2 solution. The former makes more a expensive product than an electrolytic method because the reductant, aluminium, is produced b...

The use of electro-deoxidation to reduce titanium dioxide and other metal oxides (2001)
Presentation / Conference
Fray, D. J., & Chen, G. Z. (2001, October). The use of electro-deoxidation to reduce titanium dioxide and other metal oxides. Paper presented at Proceedings of the Fourth International Conference on Materials Engineering for Resources

Titanium is usually extracted by the Kroll process in which titanium tetrachloride is reduced by magnesium to form titanium sponge and magnesium chloride. This is an expensive and time consuming process which makes titanium a very expensive metal. Al... Read More about The use of electro-deoxidation to reduce titanium dioxide and other metal oxides.
