  • Viable inflationary evolution from Einstein frame loop quantum cosmology 

    Haro Cases, Jaume; Odintsov, Sergei D.; Oikonomou, V. K. (American Physical Society (APS), 2018-04-27)
    Article
    Accés obert
    In this work we construct a bottom-up reconstruction technique for loop quantum cosmology scalar-tensor theories, from the observational indices. Particularly, the reconstruction technique is based on fixing the functional ...

  • Bulk viscous quintessential inflation 

    Haro Cases, Jaume; Pan, Supriya (2018-04-01)
    Article
    Accés restringit per política de l'editorial
    In a spatially-flat Friedmann–Lemaître–Robertson–Walker universe, the incorporation of bulk viscous process in general relativity leads to an appearance of a nonsingular background of the universe that both at early and ...

  • Teaching engineers in the seventeenth century: european influences in Portugal 

    Fialho Conde, Antónia; Massa Esteve, Maria Rosa (2018-06-09)
    Article
    Accés restringit per política de l'editorial
    The practice of mathematics underwent a major transformation in the seventeenth century due to new procedures and concepts that also showed their utility for military architecture. The circulation of this knowledge can be ...

  • Antisymmetry of solutions for some weighted elliptic problems 

    Cabré Vilagut, Xavier; Lucia, Marcello; Sanchón, Manel; Villegas, Salvador (2018-03-17)
    Article
    Accés restringit per política de l'editorial
    This article concerns the antisymmetry, uniqueness, and monotonicity properties of solutions to some elliptic functionals involving weights and a double well potential. In the one-dimensional case, we introduce the continuous ...

  • Las habilidades sociales del docente universitario: una formación hacia la competencia interpersonal 

    Gómez Soberón, José Manuel Vicente; Berbegal-Mirabent, Jasmina; Cañabate Carmona, Antonio; Farrerons Vidal, Óscar; Montero Mercadé, Lídia; Mora Giné, Mercè; Santos Boada, Germán; Torre Martínez, María del Rocío de la; Del Corral, Ignacio; Huerta Carrillo, María (2014-07-14)
    Article
    Accés obert
    Desde el ICE de la UPC se ha planteado una nueva formación dirigida a todo el profesorado basada en la adquisición de competencias docentes. Uno de los módulos de formación puesto en marcha trabaja la adquisición de la ...

  • On geometric quantization of b-symplectic manifolds 

    Miranda Galcerán, Eva; Guillemin, Victor; Weitsman, Jonathan (2018-05-20)
    Article
    Accés obert
    We study a notion of pre-quantization for b-symplectic manifolds. We use it to construct a formal geometric quantization of b-symplectic manifolds equipped with Hamiltonian torus actions with nonzero modular weight. We ...

  • One inspection is not enough to estimate durability in building : a simulation study 

    Serrat Piè, Carles (2011)
    Comunicació de congrés
    Accés obert
    Decisions about intervention in existing buildings are generally based on information gathered from inspections, as a systematic tool for the identification of some injury in buildings. The goal of this research is to ...

  • Combinatorial structures to construct simple games and molecules 

    Molinero Albareda, Xavier (2017-03-01)
    Article
    Accés obert
    We connect three different topics: combinatorial structures, game theory and chemistry. In particular, we establish the bases to represent some simple games, defined as influence games, and molecules, defined ...

  • Hopf bifurcation for the hydrogen atom in a circularly polarized microwave field 

    Ollé Torner, Mercè; Pacha Andújar, Juan Ramón (2018-09-01)
    Article
    Accés obert
    We consider the Rydberg electron in a circularly polarized microwave field, whose dynamics is described by a Hamiltonian depending on one parameter, K¿>¿0. The corresponding Hamiltonian system of ODE has two equilibrium ...

  • Distributing the global carbon budget with climate justice criteria 

    Alcaraz Sendra, Olga; Buenestado Caballero, Pablo; Escribano Rodríguez de Robles, Beatriz; Sureda Carbonell, Bàrbara; Turon Florenza, Albert; Xercavins, Josep (2018-05-28)
    Article
    Accés restringit per política de l'editorial
    In this paper, a model for the distribution of the Global Carbon Budget between the countries of the world is presented. The model is based on the criteria of equity while also taking into account the different historical ...

  • TEC forecasting based on manifold trajectories 

    Monte Moreno, Enrique; García Rigo, Alberto; Hernández Pajares, Manuel; Yang, Heng (Multidisciplinary Digital Publishing Institute (MDPI), 2018-06-22)
    Article
    Accés obert
    In this paper, we present a method for forecasting the ionospheric Total Electron Content (TEC) distribution from the International GNSS Service’s Global Ionospheric Maps. The forecasting system gives an estimation of the ...

  • On bipartite-mixed graphs 

    Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel; López Lorenzo, Nacho (Wiley, 2018-04-24)
    Article
    Accés obert
    Mixed graphs can be seen as digraphs that have both arcs and edges (or digons, that is, two opposite arcs). In this paper, we consider the case where such graphs are bipartite. As main results, we show that in this context ...
