This study attempts to explore the possibility of estimation of linear and non-linear stiffness parameters of rolling element bearings in rotor systems experiencing harmonic excitation from unknown imbalance as well as random excitation from a variety of sources, primarily the progressive random det

Methods for using fourth order spectral quantities to estimate the unknown parameters in non-linear, randomly excited dynamic systems are developed. Attention is focused on the case where only the response is measurable and the excitation is unmeasurable and known only in terms of a stochastic proce
A method is presented for estimating an unknown parameter of a distributed parameter system which depends on the system state. The system considered is modelled by a class of non-linear partial differential equations of a parabolic type. Noisy observations are assumed to be taken through an arbitrar
