DOI: 10.1016/j.jsv.2017.09.033

Abstract: Abstract An efficient output-only Blind Source Separation (BSS) method was recently introduced for the modal identification of structures. BSS procedures recover a set of independent sources from their unknown linear mixtures when only mixtures are… read more here.

DOI: 10.1016/j.measurement.2020.108793

Abstract: Abstract Experimental modal analysis (EMA) is a well-established procedure for determining the modal parameters of a structure. Typically, a point-force is used to excite the structure and the translational response is measured. When performing an… read more here.

DOI: 10.1177/13694332241266533

Abstract: During the structural health monitoring of bridges, it has been observed that the vibration data collected can sometimes be randomly lost or sampled non-uniformly. This leads to a low signal-to-noise ratio in the spectral functions… read more here.
