Minimum relative entropy criterion for damage detection and location
Kyprianou, Andreas; Mares, C.; Charalambous, Charalambos D.; Mottershead, J. E. (2007)Relative entropy has been employed, as an alternative to other regularization methods, in solving ill-conditioned linear inverse problems. Damage detection when treated as structural modification imparted by the damage ...

Modelling and Simulation of Bolted Joints under Harmonic Excitation
Oldfield, M.; Ouyang, H.; Mottershead, J. E.; Kyprianou, Andreas (2003)Bolted metal joints under harmonic loading exhibit hysteretic behaviour. This is the major source of damping in frame structures with bolted joints, since the material damping of these structures is very small. In this ...

Modelling study of liquid crystals orientation in the presence of corrosion potential
Kossivas, P.; Kyprianou, Andreas (2010)The anchoring and orientation of liquid crystal (LC) molecules are influenced by several parameters. This paper presents theoretical work that aims to explain how surface changes and potential due to corrosion, affect the ...

A multiresolution approach to cointegration for enhanced SHM of structures under varying conditions - An exploratory study
Worden, K.; Cross, E. J.; Antoniadou, I.; Kyprianou, Andreas (2014)Cointegration has now been established as a powerful means of projecting out long-term trends from time-series data in the context of econometrics. Recent work has further established that cointegration can be applied ...

Relations between information theory, robustness and statistical mechanics of stochastic uncertain systems via large deviation theory
Charalambous, Charalambos D.; Kyprianou, Andreas; Rezaei, F. (Springer Berlin Heidelberg, 2006)Robustness issues of stochastic uncertain controlled systems are intimately related to concepts from information theory and statistical mechanics. These relations are unveiled by using the theory of large deviations through ...
