A frequency domain blind identification method for operational modal analysis using a limited number of sensors
(Sage Publications Ltd, 2020-01-14)
Operational modal analysis is an experimental modal analysis approach, which uses vibration data collected when the structure is under operating conditions. Amongst the methods for operational modal analysis, blind source ...
Reliability of using stereo photogrammetry to estimate modal parameters
(2017-01-01)
Stereophotogrammetry is a three-dimensional full-field measurement technique that has gained more importance in the area of modal analysis in the past few years. In this technique, full-field data can be taken in a single ...

Parameterized modal analysis using DIgSILENT Programming Language
(Springer International PublishingSpringer International Publishing, 2014)
A parameterized modal analysis is proposed to evaluate power system small signal stability and a simulation procedure using DIgSILENT Programming Language (DPL) is presented for this purpose. Modal analysis, or small-signal ...
