Assignment of natural frequencies by an added mass and one or more springs
Kyprianou, Andreas; Mottershead, J. E.; Ouyang, H. (2004)The problem of assigning natural frequencies to a multi-degree-of-freedom undamped system by an added mass connected by one or more springs is addressed. The added mass and stiffnesses are determined using receptances from ...

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 ...

Disturbance attenuation of uncertain beams
Kyprianou, Andreas; Mares, C. (Katholieke Universiteit Leuven, 2008)In control theory disturbance attenuation is analyzed by the H8 theory and through certain dissipation inequalities. Even though this theory has been applied in controlling deterministic vibrating structures the control ...

Estimation of rotational frequency responses
Mottershead, J. E.; Kyprianou, Andreas; Ouyang, H. (2003)Rotational frequency response functions are potentially valuable for structural damage detection but are difficult to obtain because of the practical problems of applying a pure moment. In the literature various indirect ...

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 ...
