  • Advanced methodology for wind resource assessment near hydroelectric dams in complex mountainous areas 

    Yang, Lin; Rojas Gregorio, José Ignacio; Villardi de Montlaur, Adeline de (2019-11-05)
    Article
    Restricted access - publisher's policy
    To increase renewable energy generation in some hydroelectric dams, a solution consisting in installing wind turbines close to dams is proposed. Indeed, dam surroundings are prone to benefit from wind speed-up effect, extra ...
  • Evidence for a dynamics crossover and its implication on the freezing temperature determination of relaxor ferroelectrics 

    Levit Valenzuela, Rafael; Ochoa Guerrero, Diego A.; Martínez García, Julio Cesar; García García, José Eduardo (Institute of Physics (IOP), 2019-09-27)
    Article
    Restricted access - publisher's policy
    Relaxor ferroelectrics are characterized by a broadened and dispersive permittivity peak in their temperature-dependent dielectric spectra. Although several models have been proposed to explain the nature of these materials, ...
  • Regularization of vertical-cavity surface-emitting laser emission by periodic non-Hermitian potentials 

    Ahmed, Waqas Waseem; Herrero Simon, Ramon; Botey Cumella, Muriel; Wu, Ying; Staliunas, Kestutis (2019-08-15)
    Article
    Restricted access - publisher's policy
    We propose a novel physical mechanism based on periodicnon-Hermitian potentials to efficiently control the complexspatial dynamics of broad-area lasers, particularly in vertical-cavity surface-emitting lasers (VCSELs), ...
  • Delay effects on the limit cycling behavior in resonant inverters with state feedback 

    Benadero García-Morato, Luis; El Aroudi, Abdelali; Ponce, Enrique (2019-10-01)
    Article
    Restricted access - publisher's policy
    Bifurcations of limit cycles in an H-bridge LC resonant inverter are reexamined taking into account a time delay in the switching transition. The analysis is accomplished by means of a model of the inverter that compresses, ...
  • Comparison of various guidance strategies to achieve time constraints in optimal descents 

    Dalmau Codina, Ramon; Prats Menéndez, Xavier; Verhoeven, Ronald; Bussink, Frank; Heesbeen, Bart (2019-01-01)
    Article
    Open Access
    Continuous Descent Operations (CDOs) have been subject of extensive research in the last decades. Even if proving successful in reducing the environmental impact [1], such operations suffer from a well-known drawback: the ...
  • [60]Fullerene for medicinal purposes, a purity criterion towards regulatory considerations 

    Keykhosravi, Sanaz; Rietveld, Ivo B.; Couto, Diana; Tamarit Mur, José Luis; Barrio Casado, María del; Céolin, René; Moussa, Fathi (Multidisciplinary Digital Publishing Institute (MDPI), 2019-08-01)
    Article
    Open Access
    Since the early nineties countless publications have reported promising medicinal applications for [60]fullerene (C60) related to its unparalleled affinity towards free radicals. Yet, until now no officially approved ...
  • The full lepton flavor of the littlest Higgs model with T-parity 

    del Aguila Jiménez, Francisco; Ametller Congost, Lluís; Illana, José Ignacio; Santiago, Jose; Talavera, Pere; Vega-Morales, Roberto (Springer, 2019-07-25)
    Article
    Open Access
    We re-examine lepton flavor violation (LFV) in the Littlest Higgs model with T-parity (LHT) including the full T-odd (non-singlet) lepton and Goldstone sectors. The heavy leptons induce two independent sources of LFV ...
  • A dynamic load balancing method for the evaluation of chemical reaction rates in parallel combustion simulations 

    Muela Castro, Jordi; Borrell Pol, Ricard; Ventosa Molina, Jordi; Jofre Roca, Lluís; Lehmkuhl Barba, Oriol; Pérez Segarra, Carlos David (Elsevier, 2019-08-15)
    Article
    Restricted access - publisher's policy
    The development and assessment of an efficient parallelization method for the evaluation of reaction rates in combustion simulations is presented. Combustion simulations where the finite-rate chemistry model is employed ...
  • An experimental and numerical study of repairs on composite substrates with composite and aluminum doublers using riveted, bonded, and hybrid joints 

    Pitta, Siddharth; Roure Fernández, Francisco; Crespo Artiaga, Daniel; Rojas Gregorio, José Ignacio (Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-14)
    Article
    Open Access
    In this work, experimental and numerical analyses of repairs on carbon fiber reinforced epoxy (CFRE) substrates, with CFRE and aluminum alloy doublers typical of aircraft structures, are presented. The substrates have a ...
  • One-dimensional harmonically confined SU(N) fermions 

    Gordillo Bargueño, Maria Carmen; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (American Physical Society (APS), 2019-08-05)
    Article
    Open Access
    We study the momentum distributions and spatial correlations of few harmonically confined SU(N) fermions using quantum Monte Carlo methods. In our study, we vary the spin degeneracy N from 2 to 6 and the total number of ...
  • The generalized Vogel-Fulcher-Tamman equation for describing the dynamics of relaxor ferroelectrics 

    Levit Valenzuela, Rafael; Martínez García, Julio Cesar; Ochoa Guerrero, Diego A.; García García, José Eduardo (Nature, 2019-08-27)
    Article
    Open Access
    Relaxor ferroelectrics (RF) are outstanding materials owing to their extraordinary dielectric, electromechanical, and electro-optical properties. Although their massive applications, they remain to be one of the most ...
  • Assessing beach and dune erosion and vulnerability under sea level rise: a case study in the Mediterranean Sea 

    Rodríguez Enríquez, Alejandra; Marcos Moreno, Marta; Falqués Serra, Albert; Roelvink, Dano (2019-01-25)
    Article
    Open Access
    In this study, we estimate the shoreline retreat, the vulnerability and the erosion rates of an open beach-dune system under projected sea level rise (SLR) and the action of wind-waves (separately and in combination). The ...
