    Article
    Accés restringit per política de l'editorial
    The modulation by the Atlantic multidecadal variability (AMV) of the dynamical climate response to a Pinatubo-like eruption is investigated for the boreal winter season based on a suite of large ensemble experiments using ...

  • Flow over a realistic car model: wall modeled large eddy simulations assessment and unsteady effects 

    Aljure Osorio, David E.; Calafell Sandiumenge, Joan; Baez Vidal, Aleix; Oliva Llena, Asensio (2018-03-01)
    Article
    Accés restringit per política de l'editorial
    Numerical simulations are carried out on the flow over a realistic generic car geometry, the DrivAer-fastback car model. Pure large eddy simulations (LES) and wall-modeled large eddy simulations (WMLES) are used and compared ...

  • Multi-period power management optimization for operating isolated hybrid microgrids 

    Galceran-Feixas, M.; Aragüés Peñalba, Mònica; Bullich Massagué, Eduard; Vidal Clos, J.-A; Gomis Bellmunt, Oriol (2018)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The aim of this study is to develop an algorithm for ensuring optimal operation of isolated microgrids. The generic microgrid considered consists of a set of distributed controllable generators integrated to a distribution ...

  • Application of the 2D depth-averaged model, FLATModel, to pumiceous debris flows in the Amalfi Coast 

    Papa, Maria Nicolina; Sarno, Luca; Vitiello, Francesco Saverio; Medina Iglesias, Vicente César de (2018-08-29)
    Article
    Accés obert
    Few studies about modelling pumice debris flows are available in literature. An integrated approach based on field surveys and numerical modelling is here proposed. A pumiceous debris flow, which occurred in the Amalfi ...

  • Testing the performance of sensors for ozone pollution monitoring in a citizen science approach 

    Ripoll Ruiz, Aleix; Viana, Mar; Padrosa, Marc; Querol Carceller, Xavier; Minutolo, Andrea; Hou, Kun Mean; Barceló Ordinas, José María; García Vidal, Jorge (Elsevier, 2019-02-15)
    Article
    Accés obert
    Tropospheric ozone (O3) is an environmental pollutant of growing concern, especially in suburban and rural areas where the density of air quality monitoring stations is not high. In this type of areas citizen science ...

  • Brook GLES Pi: democratising accelerator programming 

    Trompouki, Matina Maria; Kosmidis, Leonidas (Association for Computing Machinery (ACM), 2018-08-10)
    Comunicació de congrés
    Accés obert
    Nowadays computing is heavily-based on accelerators, however, the cost of the hardware equipment prevents equal access to heterogeneous programming. In this work we present Brook GLES Pi, a port of the accelerator programming ...

  • A generalized computational model for the simulation of adsorption packed bed reactors – Parametric study of five reactor geometries for cooling applications 

    Papakokkinos, Giorgos; Castro González, Jesús; Lopez, Joan; Oliva Llena, Asensio (2019-02-01)
    Article
    Accés restringit per política de l'editorial
    Environmental concerns regarding global warming and ozone depletion urge towards sustainable solutions for satisfying the increasing cooling demand. Adsorption cooling technology could form part of the solution since it ...
