      Choi-Wiliams time frequency analysis of a three degree freedom non-linear system 

      Kyprianou, Andreas; Staszewski, W.; Worden, K. (Katholieke Universiteit Leuven, 2006)
      The response of a non-linear mechanical oscillator, depending on the type of non-linearity, to an excitation of particular harmonic might contain sub- and super-harmonics, transients and chaotic components. The conventional ...

      Cointegration and nonstationarity in the context of multiresolution analysis 

      Worden, K.; Cross, E. J.; Kyprianou, Andreas (Institute of Physics Publishing, 2011)
      Cointegration has established itself as a powerful means of projecting out long-term trends from time-series data in the context of econometrics. Recent work by the current authors has further established that cointegration ...

      Differential evolution based identification of automotive hydraulic engine mount model parameters 

      Kyprianou, Andreas; Giacomin, J.; Worden, K.; Heidrich, M.; Böcking, J. (2000)
      Hydraulic engine mounts are commonly used in an automotive applications, and numerical models exist for performing full-vehicle noise, vibration and harshness (NVH) studies by means of multibody simulation. The parameters ...

      Identification of hysteretic systems using the differential evolution algorithm 

      Kyprianou, Andreas; Worden, K.; Panet, M. (2001)
      A widely used model in the field of hysteretic or memory-dependent vibrations is that of Bouc and Wen. Different parameter values extend its use to various areas of mechanical vibrations. As a consequence an identification ...

      Identification of hysteretic systems using the differential evolution algorithm 

      Kyprianou, Andreas; Worden, K. (Affiliation: Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United KingdomCorrespondence Address: Kyprianou, A.Dept. of Mechanichal Engineering, University of Sheffield, Mappin Street, Sheffield S1 3JD, United Kingdomemail: Mep96Gak@sheffield.ac.uk, 1998)
      In system identification, it is well-known that any non-linear in the parameters system, possesses a complicated error surface with many local minima. In this case the conventional algorithms, such as those based on least ...

      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 ...
