Counter-checking uncertainty calculations in Bayesian operational modal analysis with EM techniques

Counter-checking uncertainty calculations in Bayesian operational modal analysis with EM techniques

Bayesian operational modal analysis makes inference about the modal properties (e.g., natural frequency, damping ratio) of a structure using ‘output-only’ ambient vibration data. With sufficient data in applications, the posterior probability density function (PDF) of modal properties can be approxi...
