  • Asuntos de representación : Mondrian y la arquitectura moderna 

    Millán Gómez, Antonio; Díez, M. Teresa (2015)
    Article
    Accés obert
    Figurative representation in Mondrian's work evolved towards new-plastic language from a purified representation of reality. Progressive abstraction -of color and form- in search of the immutable and the bodily reduction ...
  • Asymetric modelling and control of an electronic throttle 

    Pujol Vázquez, Gisela; Vidal Seguí, Yolanda; Acho Zuppa, Leonardo; Vargas, Alessandro N. (2016-03)
    Article
    Accés obert
    This paper presents an improved model for an automotive electronic throttle inspired on the behavior observed in real-time experiments. Due to a number of issues, particularly the return-spring, the performance of the ...
  • Asymmetric light transmission by using 2D PT-symmetric photonic nanostructure 

    Turduev, M.; Botey Cumella, Muriel; Herrero Simon, Ramon; Kurt, H.; Staliunas, Kestutis; Giden, I. (Wiley-IEEE Press, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We propose for the first time a simple realization of a two-dimensional Parity-Time symmetric hexagonal shaped photonic structure composed of honeycomb lattice. The structure has a symmetric periodic modulation of the ...

  • Asymmetric soliton mobility in competing linear-nonlinear parity-time-symmetric lattices 

    Kartashov, Yaroslav V.; Vysloukh, Victor A.; Torner Sabata, Lluís (2016-09-15)
    Article
    Accés restringit per política de l'editorial
    We address the transverse mobility of spatial solitons in competing parity-time-symmetric linear and nonlinear lattices. The competition between out-of-phase linear and nonlinear lattices results in a drastic mobility ...
  • Asymmetric solitons and domain walls supported by inhomogeneous defocusing nonlinearity 

    Kartashov, Yaroslav V.; Lobanov, Valery E.; Malomed, Boris A.; Torner Sabata, Lluís (2013-12-01)
    Article
    Accés restringit per política de l'editorial
    We show that an inhomogeneous defocusing nonlinearity that grows toward the periphery in the positive and negative transverse directions at different rates can support strongly asymmetric fundamental and multipole bright ...
