We present a novel approach to harmonic disturbance removal in single-channel wind
turbine acceleration data by means of time-variant signal modeling. Harmonics are …

Many parameters can be used to express a machine's condition and to track its evolution
through time, such as modal parameters extracted from vibration signals. Operational Modal …

The possibility of determining the integrity of a real structure subjected to non-invasive and
non-destructive monitoring, such as that carried out by a series of accelerometers placed on …

In the framework of the CORTEX EU project, several measurements from different KWU and
VVER reactors have been analyzed. The goal of this project is to develop and test core …

Operational modal analysis (OMA) has recently been applied to the condition monitoring of
rotating machinery. Conventional OMA is based on a one-dimensional signal. The natural …

Abstract Operational Modal Analysis techniques are widely used in civil, aerospace and
industrial applications. There are several methods and one of the most utilized is Enhanced …

Vibration-based structural monitoring is an interdisciplinary field within the Structural Health
Monitoring (SHM) domain. It refers to the implementation of a strategy that allows to monitor …

The significance of rotating machinery spans areas from household items to vital industry
sectors, such as aerospace, automotive, railway, sea transport, resource extraction, and …

Rotating machinery, especially if powered by electric motors in a lab environment, can
exhibit a low amount of random operational excitation. This can inhibit the excitation of …

Este trabalho apresenta um estudo geral sobre a aplicabilidade de métodos de
aprendizado de máquina não supervisionado combinados a métodos da Análise Modal …
