Large-Eddy Simulation of Low-Frequency Flow Oscillations for NACA0012 and Dynarig Sail at Large Attack Angles

Journal of Marine Science and Engineering
Unmanned sailboats, harnessing wind for propulsion, offer great potential for extended marine research due to their virtually unlimited endurance. The sails typically operate at high attack angles, which contrasts with aircraft that maintain small angles

Music and (Touristic) Meaning on Cruise Ships: The Musicscape of the MV Carnival Paradise as a Semiotic Tourism Product [PDF]

IASPM Journal, 2014
The cruise industry is a part of the ‘post-tourism’ sector that, in contrast to cultural tourism, does not seek to represent culture for consumption by the tourist, but fabricates it, creating a hyperreal tourist experience. The music is a core aspect of

Extreme Short-Term Prediction of Unmanned Surface Vessel Nonlinear Motion Under Waves

Journal of Marine Science and Engineering
Under complex hydrodynamic conditions, Unmanned Surface Vessel (USV) exhibits non-stationary and nonlinear dynamic behaviors. Extreme short-term prediction of such nonlinear motion is therefore critical for ensuring navigational safety.
