unpublished
A two-stage Bayesian spectral density approach was formulated for ambient modal analysis recently. The interaction between spectrum variables (e.g., frequency, damping ratio as well as the magnitude of modal excitation and prediction error) and spatial variables (e.g., mode shape components) can be decoupled so that they can be identified separately. The proposed method can be implemented in the environment of a wireless sensor network through a distributed computing strategy so that local mode
