This paper presents an experimental method especially adapted for the computation of structural power flow using spatially dense vibration data measured with scanning laser Doppler vibrometers. In the proposed method. the operational deflection shapes measured over the surface of the structure are curve-fitted using a two-dimensional discrete Fourier series approximation that minimize... https://www.markbroyard.com/best-catch-acure-ultra-hydrating-plant-ceramide-daily-facial-lotion-50ml-fashion-great-buy/
