Two approaches are considered: applying the sinusoidal model to filter bank subbands, and using signal-adaptive analysis and synthesis frame sizes. These specific methods are discussed after a consideration of multiresolution as exemplified by the discrete wavelet transform....
A sinusoidally oscillating bridge deck is subjected to free-stream sinusoidal gusts to excite a nonlinear interaction between the gust-induced and motion-induced forces at large angles of attack. The interaction is examined by comparing the time-dependent forces of the CFD model with their linear ...

The proposed algorithm used the ratio of the two spectra in the vicinity of the DFT peak to compensate the signal for energy and performed multiple iterations of frequency shift. The results showed that as the number of iterations increases, the variance of frequency estimation gradually approaches...
