Filamentary extension of the mem-con theory of memristance and its application to titanium dioxide sol-gel memristors (2012)
Preprint / Working Paper

Titanium dioxide sol-gel memristors have two different modes of operation, believed to be dependent on whether there is bulk memristance, i.e. memristance throughout the whole volume or filamentary memristance, i.e. memristance caused by the connecti...

Branch cutting algorithm for unwrapping photoelastic phase map with isotropic point (2012)
Journal Article

A branch cutting algorithm is proposed to solve the wrapped isoclinic causing isochromatic discontinuity and thus to decouple the isoclinicisochromatic interaction of photoelastic phase maps. Rather than pixel by pixel, the branch-cutting isoclinic w... Read More about Branch cutting algorithm for unwrapping photoelastic phase map with isotropic point.

Modelling state of interaction from head poses for social human-robot interaction (2012)
