    Nowadays, the use of autonomous vehicles for ocean research has increased, since these vehicles have a better cost/performance ratio than crewed vessels or oceanographic ships. For example, autonomous surface vehicles can ...
  • An ocean kinetic energy converter for low-power applications using piezoelectric disk elements 

    Viñolo Monzoncillo, Carlos; Toma, Daniel; Manuel Lázaro, Antonio; Río Fernandez, Joaquín del (2013-09-30)
    Article
    Accés restringit per política de l'editorial
    The main problem facing long-term electronic system deployments in the sea, is to find a feasible way to supply them with the power they require. Harvesting mechanical energy from the ocean wave oscillations and converting ...
  • Testing otter board hydrodynamic performances in wind tunnel facilities 

    Mellibovsky Elstein, Fernando; Prat Farran, Joana d'Arc; Notti, Emilio; Sala, Antonello (2015-08-01)
    Article
    Accés restringit per política de l'editorial
    The feasibility and potential advantages of wind tunnel testing of otter board designs are assessed. Traditional flume tank tests incur high operational costs and present some limitations in terms of flexibility and accuracy. ...
