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:

Condensation of the correlation functions in modal testing
TL;DR: A method to avoid over fitting by reducing the physical channels to a reduced number of pseudo channels condensing the relevant physical information and leveling the level of energy in each channel is suggested.

Dynamic monitoring system for utility-scale wind turbines: damage detection and fatigue assessment
TL;DR: In this article, a dynamic monitoring system was developed to monitor the structural integrity of utility-scale wind turbines, based on automated techniques of operational modal analysis, aiming to deliver important information regarding the actual condition of the wind turbine: early detection of structural changes (i.e., damage) and evaluation of fatigue condition of support structure.

Modal Analysis of Fuel Injection Systems and Determination of a Transfer Function between Rail Pressure and Injection Rate
TL;DR: In this paper, a lumped parameter model of the high-pressure hydraulic circuit from the pump delivery to the injector nozzle has been realized, and the model outcomes have been validated through a comparison with frequency values that were obtained by applying the peak-picking technique to the experimental pressure traces acquired from the pipe that connects the injectors to the rail.
