  • Gain through losses in nonlinear optics 

    Perego, A.M.; Turitsyn, S.K.; Staliunas, Kestutis (2018-08-01)
    Article
    Accés obert
    Instabilities of uniform states are ubiquitous processes occurring in a variety of spatially extended nonlinear systems. These instabilities are at the heart of symmetry breaking, condensate dynamics, self-organisation, ...

  • New approaches for the fabrication of photonic structures of nonlinear optical materials 

    Carvajal, J J; Peña, A; Kumar, R.; Pujol, M. C.; Mateos, X.; Aguiló Díaz, Magdalena; Díaz, F; Vázquez De Aldana, J. R.; Méndez, Carlos Alberto; Moreno, P; Roso, L; Todorov Trifonov, Trifon; Rodríguez Martínez, Ángel; Alcubilla González, Ramón; Král, Z; Ferré Borrull, J.; Pallarès Marzal, Josep; Marsal, L F; Finizio, Sergio Di; Martorell Pena, Jordi; Macovez, Roberto (2009-12)
    Article
    Accés restringit per política de l'editorial
    We revisited two different strategies to fabricate 1D photonic crystals of nonlinear optical dielectric materials based on ultrafast laser ablation of the surface of an RbTiOPO4 crystal, and selective etching of ferroelectric ...
  • Rigid covariance, equivalence principle and Fermi rigid coordinates: gravitational waves 

    Jaen Herbera, Javier (2018-11-01)
    Article
    Accés restringit per política de l'editorial
    For a given space-time and for an arbitrary time-like geodes ic, we analyze the conditions for the construction of Fermi coordinates so that they are also rigi d covariant. We then apply these conditions to linear plane ...
  • Exergy as an indicator for enhancing evaluation of environmental management performance in the hospitality industry 

    Stylos, Nikolaos; Koroneos, Christopher; Roset Calzada, Jaime; González-Sánchez, Cynthia; Xydis, George; Muñoz Salinas, Francisco (2018)
    Article
    Accés restringit per política de l'editorial
    The importance of investigating both energy and exergy flows for assessing the environmental profile of buildings has long been acknowledged. Nevertheless, although an ample number of standalone case studies have performed ...
  • Revisit the calibration errors on experimental slant total electron content (TEC) determined with GPS 

    Nie, Wenfeng; Xu, Tianhe; Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Chen, Wu; Xu, Guochang (2018-06-26)
    Article
    Accés restringit per política de l'editorial
    The calibration errors on experimental slant total electron content (TEC) determined with global positioning system (GPS) observations is revisited. Instead of the analysis of the calibration errors on the carrier phase ...
  • White dwarf-main sequence binaries from LAMOST: the DR5 catalogue 

    Ren, J. J.; Rebassa Mansergas, Alberto; Parsons, S. G.; Liu, X. W; Luo, Jun; Kong, X; Zhang, C. (Oxford University Press, 2018-07-01)
    Article
    Accés obert
    We present the data release (DR) 5 catalogue of white dwarf–main sequence (WDMS) binaries from the Large sky Area Multi-Object fibre Spectroscopic Telescope (LAMOST). The catalogue contains 876 WDMS binaries, of which 757 ...
  • Conflict-free trajectory optimization with target tracking and conformance monitoring 

    Vilardaga García-Cascón, Santi; Prats Menéndez, Xavier; Duan, Pengfei; Uijt de Haag, Maarten (2018-05-01)
    Article
    Accés obert
    This paper proposes an optimization framework that computes conflict-free optimal trajectories in dense terminal airspace, while continuously monitoring trajectory conformance in an effort to improve predictability. The ...
  • Influence of carbon content on microstructure and properties of a steel matrix cermet 

    Alvaredo Olmos, Paula; Bruna Escuer, Pere; Crespo Artiaga, Daniel; Gordo Odériz, Elena (2018-09-01)
    Article
    Accés restringit per política de l'editorial
    There is a marked correlation between the composition, microstructure and properties in TiCN-based cermets. In the case of using iron alloys as metallic matrix the carbon content is of particular significance, as not only ...
  • The population of single and binary white dwarfs of the Galactic bulge 

    Torres Gil, Santiago; García-Berro Montilla, Enrique; Cojocaru, Elena Ruxandra; Calamida, Annalisa (Oxford University Press, 2018-05-01)
    Article
    Accés obert
    Recent Hubble Space Telescope observations have unveiled the white dwarf cooling sequence of the Galactic bulge. Although the degenerate sequence can be well fitted employing the most up-to-date theoretical cooling sequences, ...
  • Assessment of advanced natural ventilation space cooling potential across southern European coastal region 

    Pesic, Nikola; Roset Calzada, Jaime; Muros Alcojor, Adrián (2018-09)
    Article
    Accés obert
    Analyzing the Köppen–Geiger climate classification and available climate data for the southern European Mediterranean coast, eight reference geolocations were selected for this analysis: the cities of Valencia, Barcelona, ...
  • The extreme floods in the Ebro River basin since 1600 CE 

    Balasch Solanes, Josep Carles; Pino González, David; Ruiz Bellet, Josep Lluís; Tuset Mestre, Jordi; Barriendos Valve, Mariano; Castelltort, Xavier; Peña, Juan Carlos (Elsevier, 2018-07-28)
    Article
