    La gamificación es una estrategia metodológica que hace referencia a la integración de elementos del diseño de juegos en actividades de aprendizaje. Una forma de aplicar la gamificación es el Escape room, en el que se ...
  • A novel condition monitoring methodology based on neural network of pump-turbines with extended operating range 

    Zhao, Weiqiang; Egusquiza Estévez, Eduard; Valero Ferrando, Ma. del Carmen; Egusquiza Montagut, Mònica; Valentín Ruiz, David; Presas Batlló, Alexandre (2019)
    Conference report
    Open Access
    Due to the entrance of new renewable energies, water-storage energy has to be regulated more frequently to keep the stability of power grid. Consequently, pump-turbines have to work under offdesign conditions more than ...
  • Natural frequencies of rotating disk-like structures submerged viewed from the stationary frame 

    Presas Batlló, Alexandre; Valentín Ruiz, David; Egusquiza Estévez, Eduard; Valero Ferrando, Ma. del Carmen; Seidel, Ulrich (2021)
    Conference report
    Open Access
    To understand the effect of rotation in the dynamic response of pump-turbine runners, simplified models such as disk-like structures can be used. In previous researches the natural frequencies and mode shapes of rotating ...
