Análise modal operacional de uma bomba centrífuga submersa utilizando a decomposição melhorada no domínio da frequência
… modal analysis method employed was the Enhanced Frequency Domain Decomposition (EFDD). The same method was used to identify the modal parameters through impact tests. An EFDD algorithm was developed and tested using theoretical signals and impact test performed on a metal bar. In the case study, …

Dynamic modelling of arch dams in the ambient state
… on the cantilevered arch blocks. Finally, the Frequency Domain Decomposition (FDD) algorithm was used to analyse the acquired data and identify the natural frequencies of the dam.

Automatic operational modal analysis: challenges and applications to historic structures and infrastructures
… based on the inspection of any irreversible frequency variation. To such purpose, it is mandatory an extensive correlation study with environmental and operational factors which affect the frequency of the vibration modes. Conversely, one of the proposed strategy aims to use alternative …
