Abstract: In this paper, a time series based detection algorithm is proposed utilizing the Gaussian Mixture Models. The two critical aspects of damage diagnosis that are investigated are detection and ...

Abstract: In this paper, a damage sensitive feature based on the wavelet transform of the vibration signal is derived. The theoretical aspects of wavelet decomposition of vibration signals are presented. ...

Abstract: The uncertainties related to the inherent properties of pavement subgrade subjected to the dynamic effect of vehicular and earthquake loading were studied extensively using probabilistic analysis. The dynamic effect of the ...

Abstract: This paper introduces three wavelet-based damage-sensitive features (DSFs) extracted from structural responses recorded during earthquakes to diagnose structural damage. Because earthquake excitations are nonstationary, ...
