... is that the encountered wave elevation must be independently predicted with suf cient accuracy in real time. A lot of efforts have been made to acquire ocean wave information in the literature. Many researchers have attempted to reconstruct and predict ocean wave environments based on X-band radar measurement data...

..., the root mean squared error (RMSE) was reduced by 30 cm at Hitachinaka and Tsuruga. We constructed CNNs for wave predictions at arbitrary locations and confirmed a positive correlation between the accuracy of DA and the prediction accuracy of the CNNs. When actual wind data were fed to the CNNs...

... modeling. Its accuracy is validated by comparing its prediction with the experimental data. The results show that the lift coefficient and lift-to-drag ratio reach their maxima when the angles of attack are 25. and 10., respectively. The lift coefficient increases with increasing aspect ratio and relative...
