A class of delayed oscillators and coupled systems to oscillation of El Nio-Southern Oscillation (ENSO) models are considered. Using the perturbed theory and
A reformed numerical model based on the “one-line theory” for beach deformation is presented. In this model, the change of beach slope during coastline proces
The underwater acoustic field influenced by a selected ocean internal wave was computed using the Parabolic Equation (PE) method and split-step difference algor
