  • Engineering of multicolor spatial solitons with chirped-period quasi-phase-matching gratings in optical parametric amplification 

    Schober, A M; Fejer, M M; Carrasco, S; Torner Sabata, Lluís (2005-08)
    Article
    Accés restringit per política de l'editorial
    We demonstrate the excitation of solitons in a parametric amplifier with enhanced signal content through the use of a chirped-period quasi-phase-matching grating. This technique affords a low soliton threshold at the input ...
  • Stable spatiotemporal solitons in Bessel optical lattices 

    Mihalache, Dumitru; Mazilu, D; Lederer, F; Malomed, B A; Kartashov, Yaroslav V.; Crasovan, L C; Torner Sabata, Lluís (2005-08)
    Article
    Accés restringit per política de l'editorial
    We investigate the existence and stability of three-dimensional solitons supported by cylindrical Bessel lattices in self-focusing media. If the lattice strength exceeds a threshold value, we show numerically, and using ...
  • Stable three-dimensional solitons in attarctive Bose-Einstein condensates loaded in an optical lattice 

    Mihalache, Dumitru; Mazilu, D; Lederer, F; Malomed, B A; Crasovan, L C; Kartashov, Yaroslav V.; Torner Sabata, Lluís (2005-08)
    Article
    Accés restringit per política de l'editorial
    The existence and stability of solitons in Bose-Einstein condensates with attractive interatomic interactions, described by the Gross-Pitaevskii equation with a three-dimensional (3D) periodic potential, are investigated ...
  • The spatial shape of entangled photon states in non-collinear, walking parametric downconversion 

    Pérez Torres, Juan; Molina Terriza, Gabriel; Torner Sabata, Lluís (2005-08)
    Article
    Accés restringit per política de l'editorial
    We address the spatial shape of entangled photon states generated in spontaneous parametric downconversion in non-collinear geometries, when the interacting waves exhibit Poynting vector walk-off. We discuss how such shape ...
  • Soliton topology versus discrete symmetry in optical lattices 

    Kartashov, Yaroslav V.; Ferrando, A; Egorov, A A; Torner Sabata, Lluís (2005-09)
    Article
    Accés restringit per política de l'editorial
    We address the existence of vortex solitons supported by azimuthally modulated lattices and reveal how the global lattice discrete symmetry has fundamental implications on the possible topological charges of solitons. We ...
  • Diseño de un sistema de disipación de energía para un edifico en altura 

    Palazzo, G.; López Almansa, Francisco; Roldán, Víctor; Calderón, Francisco (Asociación Chilena de Sismología e Ingeniería Antisísmica, 2015)
    Text en actes de congrés
    Accés obert
    Se considera en este trabajo un edificio sismorresistente aporticado de hormigón armado, de 21 niveles, diseñado para Guayaquil, Ecuador. El objetivo del estudio es desarrollar un procedimiento de diseño de un sistema de ...
  • Cuatro notas para un centenario 

    Granell Trias, Enrique (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    Con motivo del centenario del nacimiento del poeta y crítico de arte Juan Eduardo Cirlot, el autor publica documentos inéditos que interpretan facetas hasta ahora no tratadas de Cirlot.
  • Comparison between several criteria for selecting the parameters of hysteretic energy dissipators for seismic protection of steel building structures 

    Domínguez Santos, David Jesús; López Almansa, Francisco; Benavent Climent, Amadeo (China Architecture & Building Press, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This work deals with seismic protection of steel building structures using hysteretic energy dissipators. The sensitivity of the performance of these systems to the design parameters of the dissipative devices is numerically ...
  • Cost comparison of MRF, CBF and EBF mid-height steel buildings in Bogotá 

    López Almansa, Francisco; Montaña Peña, Miguel Angel (China Architecture & Building Press, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A number of mid-height steel buildings have been recently erected in Bogotá (Colombia). Their seismic risk might be high, given the new current microzonation of Bogotá and the lack of comprehensive previous studies. This ...
  • Enzymatic pretreatment of microalgae using fungal broth from Trametes versicolor and commercial laccase for improved biogas production 

    Hom Diaz, Andrea; Passos, Fabiana Lopes del Rei; Ferrer Martí, Ivet; Vicent, Teresa; Blánquez, Paqui (Elsevier, 2016-11)
    Article
    Accés restringit per política de l'editorial
    Coupling microalgae production to wastewater treatment can reduce the costs of microalgae production for non-food bioproducts and energy consumption for wastewater treatment. Furthermore, microalgae anaerobic digestion can ...
