Basis-updating for data compression of displacement maps from dynamic DIC measurements

TL;DR: A new algorithm is presented that addresses the need for efficiency in full-field data processing by making use of the data itself and combining the concept of sparse representation with Gram-Schmidt orthogonalisation, and the number of basis function used to represent the data can be reduced and a concise decomposition established.

Quickest detection in coupled systems

TL;DR: It is proved that the minimum of N CUSUMs is asymptotically optimal as the mean time between false alarms increases without bound.

Machine-learning-based methods for output-only structural modal identification

TL;DR: In this article, a self-coding deep neural network is designed to identify the structural modal parameters from the vibration data of structures, and a complex loss function is used to restrict the training process of the neural network, making the output of the third layer the modal responses we want, and the weights of the last two layers are mode shapes.

An automated operational modal analysis algorithm and its application to concrete dams

TL;DR: In this article , a three-stage automated OMA algorithm based on a combination of the second-order blind identification (SOBI) and the covariance-driven stochastic subspace identification (SSI-COV) is proposed, which takes full advantage of both parametric and nonparametric algorithms while overcoming the limitations.

A framework for quantifying the value of vibration-based structural health monitoring

TL;DR: In this paper , the authors present a framework for quantification of the value of vibration-based structural health monitoring (SHM) which can be flexibly applied to different use cases, from near real time diagnostics to the prognosis of slowly evolving deterioration processes over the lifetime of a structure.
