  • Canonical realization of (2+1)-dimensional Bondi-Metzner-Sachs symmetry 

    Batlle Arnau, Carles; Campello, Víctor; Gomis Torné, Joaquin (2017-07-12)
    Article
    Accés obert
    We construct canonical realizations of the (2+1)-dimensional Bondi-Metzner-Sachs (bms3) algebra as symmetry algebras of a free Klein-Gordon (KG) field in 2+1 dimensions for both massive and massless cases. We consider two ...
  • Non-relativistic Bondi-Metzner-Sachs algebra 

    Batlle Arnau, Carles; Delmastro, Diego; Gomis Torné, Joaquin (2017-09-21)
    Article
    Accés obert
    We construct two possible candidates for non-relativistic bms(4) algebra in four space-time dimensions by contracting the original relativistic bms(4) algebra. bms(4) algebra is infinite-dimensional and it contains the ...
  • PM-Assisted Synchronous Reluctance Machine flux weakening control for EV and HEV applications 

    Trancho, Elena; Ibarra Basabe, Edorta; Arias Pujol, Antoni; Kortabarria, Iñigo; Jurgens, Jonathan; Marengo, Luca; Fricasse, Antonio; Gragger, Johannes (Institute of Electrical and Electronics Engineers (IEEE), 2017-08-31)
    Article
    Accés obert
    IEEE In this manuscript, a novel robust torque control strategy for Permanent Magnet Assisted Synchronous Reluctance Machine drives applied to electric vehicles and hybrid electric vehicles is presented. Conventional control ...
  • Distributed parameter model-based control of water activity and concentration of reactants in a polymer electrolyte membrane fuel cell 

    Sarmiento Carnevali, Maria Laura; Serra, Maria; Batlle Arnau, Carles (2017-01-01)
    Article
    Accés restringit per política de l'editorial
    Water management is still a key challenge for optimal performance and durability of polymer electrolyte membrane (PEM) fuel cells. Water levels along the channel in a PEM fuel cell present important spatial variations that ...
  • Energy management strategy for fuel cell-supercapacitor hybrid vehicles based on prediction of energy demand 

    Carignano, Mauro; Costa Castelló, Ramon; Roda Serrat, Vicente; Nigro, Norberto; Junco, Sergio; Feroldi, Diego Hernan (2017-08-31)
    Article
    Accés restringit per política de l'editorial
    Offering high efficiency and producing zero emissions Fuel Cells (FCs) represent an excellent alternative to internal combustion engines for powering vehicles to alleviate the growing pollution in urban environments. Due ...
  • Observation of the electrochemically active surface area in a proton exchange membrane fuel cell 

    Luna Pacho, Julio Alberto; Usai, Elio; Husar, Attila Peter; Serra, Maria (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés obert
    In this paper a methodology for the estimation of the Electrochemically active Surface Area (ECSA) of a Proton Exchange Membrane Fuel Cell (PEMFC) is developed. Specifically, the ECSA in the Cathode Catalyst Layer (CCL) ...
  • Tachyons in the Galilean limit 

    Batlle Arnau, Carles; Gomis Torné, Joaquin; Mezincescu, Luca; Townsend, Paul K. (2017-04-20)
    Article
    Accés obert
    The Souriau massless Galilean particle of “colour” k and spin s is shown to be the Galilean limit of the Souriau tachyon of mass m = ik and spin s. We compare and contrast this result with the Galilean limit of the Nambu-Goto ...
  • Nonlinear predictive control for durability enhancement and efficiency improvement in a fuel cell power system 

    Luna Pacho, Julio Alberto; Jemei, Samir; Yousfi-Steiner, Nadia; Husar, Attila Peter; Serra, Maria; Hissel, Daniel (2016)
    Article
    Accés obert
    In this work, a nonlinear model predictive control (NMPC) strategy is proposed to improve the efficiency and enhance the durability of a proton exchange membrane fuel cell (PEMFC) power system. The PEMFC controller is based ...
  • Extended Galilean symmetries of non-relativistic strings 

    Batlle Arnau, Carles; Gomis Torné, Joaquin; Not, Daniel (2017-02-09)
    Article
    Accés obert
    We consider two non-relativistic strings and their Galilean symmetries. These strings are obtained as the two possible non-relativistic (NR) limits of a relativistic string. One of them is non-vibrating and represents a ...
  • Nonlinear model predictive control methodology for efficiency and durability improvement in a fuel cell power system 

    Luna Pacho, Julio Alberto; Jemei, Samir; Yousfi-Steiner, Nadia; Husar, Attila Peter; Serra, Maria (2016)
    Text en actes de congrés
    Accés obert
    The main contribution of this work is the improvement of the efficiency of a PEMFC power system while guaranteeing conditions that also improve its durability. Adopting the NMPC scheme with the distributed parameter model ...
