WebOn the interaction of ocean waves and turbulence by José F. Beyá A thesis submitted for the degree of Master of Engineering by Research School of Civil and Environmental Engineering WebIn this thesis, we mainly target two different types of problems-mapping highly nonlinear physical relations and predicting time series, to prove the feasibility of such a framework. More specifically, one problem is the short-term wave prediction based on realtime measurements and its application to the advanced controls of renewable energy.
