Abstract: This paper presents a method for estimating Coulomb and viscous friction coefficients from responses of a harmonically excited dual-damped oscillator with linear stiffness. The identification method ...

Abstract: Wavelet transforms were compared between various simulated friction models and real stick-slip data. While simulations of several models produced stick-slip transition oscillations seen in the real ...

Abstract: This study addresses the identification of nonlinear systems. It is assumed that the function form in the nonlinear system is known, leaving some unknown parameters to be estimated. Since Haar ...

Abstract: AbstractA novel approach to estimate the effective ionic diffusivity of concrete is introduced in this paper. The ionic diffusivity in pore solution is calculated considering interactions between ions. Based on conductivity ...
