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:

Static and dynamic testing of a full-composite VLA by using digital image correlation and output only ground vibration testing
TL;DR: Particular attention is dedicated to demonstrating the reliability of some innovative techniques, such as the Digital Image Correlation (DIC), the operational modal analysis (OMA) and the taxing vibration test (TVT), which cannot yet be used for certification purposes.

Output-only modal identification based on hierarchical Hough transform
TL;DR: In this article, a hierarchical Hough transform is applied to the TF coefficients hierarchically to identify the hyperplanes and the mixing matrix is calculated, and the modal responses are recovered by using l 1 -optimization and inverse STFT.

Uncertainty quantification for joint input-state estimation in structural dynamics
TL;DR: The uncertainty quantification approach is applied for a joint input-state estimation algorithm that is used for force identification and response estimation in structural dynamics and can be extended to other force and state estimation algorithms.
Structural Reliability Updating with Stochastic Subspace Damage Detection Information
Sebastian Thöns,Michael Döhler +1 more
TL;DR: The potential of the utilization of damage detection information for more reliable structural systems are demonstrated as the determination of a probability of detection distribution function for damage detection algorithms accounting for the relevant uncertaintie s and the concept of Bayesian updating of the structural reliability.
