    Article
    Restricted access - publisher's policy
    The present paper extends the conservative finite element convective scheme proposed by Charnyi et al.(Journal of Computational Physics 337, 2017, 289–308) originally formulated for incompressible flows to the low Mach ...
  • Urgent supercomputing of earthquakes: use case for civil protection 

    Puente, Josep de la; Rodríguez Rodríguez, Juan Esteban; Monterrubio Velasco, Marisol; Rojas, Otilio (Association for Computing Machinery (ACM), 2020)
    Conference report
    Open Access
    Deadly earthquakes are events that are unpredictable, relatively rare and have a huge impact upon the lives of those who suffer their consequences. Furthermore, each earthquake has specific characteristics (location, ...
  • Modeling active fault systems and seismic events by using a fiber bundle model – example case: the Northridge aftershock sequence 

    Monterrubio Velasco, Marisol; Zúñiga, F. Ramón; Carrasco Jiménez, José Carlos; Márquez Ramírez, Víctor; Puente, Josep de la (Copernicus Publications, 2019)
    Article
    Open Access
    Earthquake aftershocks display spatiotemporal correlations arising from their self-organized critical behavior. Dynamic deterministic modeling of aftershock series is challenging to carry out due to both the physical ...
  • Active flow control for external aerodynamics: from micro air vehicles to a full aircraft in stall 

    Lehmkuhl, Oriol; Lozano-Durán, Adrian; Rodríguez Pérez, Ivette María (Institute of Physics (IOP), 2020-04-01)
    Article
    Open Access
    We investigate the aerodynamic performance of active flow control of airfoils and wings using synthetic jets with zero net-mass flow. The study is conducted via wall-resolved and wall-modeled large-eddy simulation using ...
  • Probing the strongly driven spin-boson model in a superconducting quantum circuit 

    Magazzù, Luca; Forn Diaz, Pol; Belyansky, Ron; Orgiazzi, Jean-Luc; Yurtalan, Muhammet; Otto, Martin R.; Lupascu, Adrian; Wilson, Christopher; Grifoni, Milena (2018-04-11)
    Article
    Open Access
    Quantum two-level systems interacting with the surroundings are ubiquitous in nature. The interaction suppresses quantum coherence and forces the system towards a steady state. Such dissipative processes are captured by ...
