Wavelet transform modulus maxima decay lines: Damage detection in varying operating conditions
(IGI Global, 2015)An important task in structural health monitoring (SHM) is that of damage detection under varying environmental and operational conditions. Structures, under varying environmental conditions, change their mass, elasticity ...

Identification of hysteretic systems using the differential evolution algorithm
(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 ...

Differential evolution based identification of automotive hydraulic engine mount model parameters
(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 ...

The effect of correlated and point defects on the vortex lattice melting transition in single-crystal YBa2Cu3O7-δ
(1994)The vortex melting transition Tm in several untwinned and twinned crystals is measured resistively in fields up to 8T. A Lindemann criterion for vortex lattice melting is obtained in addition to a sharp hysteresis in the ...

Stochastic control for nanoparticle manipulation using electric fields
(2018)A simplified model is used to study the dynamics of a nanoparticle suspended in a fluid under Dielectrophoretic (DEP) force. The model considers the DEP force (considering only dipoles formed and not higher order polarisation) ...

Disturbance attenuation of uncertain beams
(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 ...
