Random model of vibrations for Foreign Object Damage detection in a civil aircraft engine
TL;DR: First evidence that a windowed autoregressive model may be used to detect the shock after it occurred is shown, and the windowed AR estimation algorithm seems to perform better than the adaptive one.

Robust early detection of hunting on railway vehicles: single-sensor based methods and critical comparisons
TL;DR: In this paper , two single-sensor "dynamics-based" methods employing adaptive recursive auto-regressive (RAR) modelling of the car-body lateral random vibration signal are postulated.
Basis Function Selection Criterion for Modal Monitoring of Non Stationary Systems
TL;DR: This paper introduces a criterion called Basis Function Selection Criterion which is based on the minimization of the difference between the model parameters estimated by two methods, namely FS-VTAR and the classic stationary VAR.

An Extended Modal Identification for Linear Periodically Time-Varying Systems Based on Stability-Preserving State Transformation
TL;DR: In this article, an extended modal identification method was proposed to extract the time-varying modes and poles of linear periodically time changing (LPTV) systems, where a set of poles defines a stability-preserving transformation relat ing the original LPTV state equation to a constant upper triangular state equation.

Parameter Estimation via Fokker-Planck Type Residual: Application to Linear Stationary Random Vibration
TL;DR: In this article, the authors proposed a new method that is useful for estimating unknown parameter values of stochastic differential equation (SDE) models, based on probability density function (PDF) data measured from random dynamical systems.

Estimating the Dimension of a Model
TL;DR: In this paper, the problem of selecting one of a number of models of different dimensions is treated by finding its Bayes solution, and evaluating the leading terms of its asymptotic expansion.
