... ABSTRACT The paper deals with a prediction procedure from which global wave-induced responses can be deterministically predicted a short time, 10–50 s, ahead of current time. The procedure relies on the autocorrelation function and takes into account prior measurements only; i.e. knowledge...

... to derive the free decay signal, from which the damping ratios were estimated. In addition, the autocorrelation functions of the filtered signal were calculated and a comparison was made with the free decay signal obtained from the random decrement technique. The wet damping ratios for each sea state group...

.... The nonlinear wave force spectrum and fatigue stress spectrum are achieved using the autocorrelation function and the Fourier transform. The fluctuating wind load acted on the rotor is analyzed based on the BEM (blade element momentum) theory. We use a 1.5MW wind turbine model for the simulations; calculate...

... component being zero-mean Gaussian processes, the relationship between autocorrelation functions of wave profile and the first order wave component is established using the nonlinear spectral analysis. The spectral densities of nonlinear random waves are then obtained. An experience formula is proposed...

... Boussinesq equations. The method of spectral evaluation from autocorrelation function is used in the analysis of the numerical results. INTRODUCTION Prediction for wave transformation in the nearshore region often is necessary in engineering applications. The Boussinesq equations, after years...
