TLDR
In this paper, a novel approach of stochastic subspace identification is presented that incorporates the idea of the reference sensors already in the identification step: the row space of future outputs is projected into the rowspace of past reference outputs.About:

Cyclostationarity and the cepstrum for operational modal analysis of mimo systems-Part I Modal parameter identification
TL;DR: In this article, the cyclostationary properties of the input are exploited to estimate the cyclic spectral density, effectively reducing the system from a MIMO to a single input multiple output (SIMO) situation, and curve-fitted in the cepstrum domain.

Model Updating of Historical Belfries Based on Oma Identification Techniques
TL;DR: Central Italy Earthquakes occurred in 2016 pointed out once more the vulnerability of Cultural Heritage (CH), especially for what concerns bell-towers since they tend to get dramatically damaged as mentioned in this paper.

Vibration-based damage localization and quantification in a pretensioned concrete girder using stochastic subspace identification and particle swarm model updating:
TL;DR: A novel methodology for extracting and analyzing distributed acceleration data for condition assessment of bridge girders is proposed, enabling robust damage detection, localization, and quantification and can be used to create a high-fidelity finite element model of the girder that could be leveraged for condition prognosis and forecasting.
Journal ArticleDOI
Scaling-factor estimation using an optimized mass-change strategy
TL;DR: In this article, a procedure to optimize the mass-change strategy is proposed, which uses the modal parameters (natural frequencies and mode shapes) of the original structure as the basic information.
Journal ArticleDOI
Use of instantaneous estimators for the evaluation of structural damping
TL;DR: In this paper, the authors defined the definition of time-frequency instantaneous estimators to be employed in the identification of structural damping from signals measured in ambient vibration conditions and applied them to linear timefrequency representations of dynamic response signals.
