  • Soliton content with quadratic nonlinearities 

    Artigas García, David; Torner Sabata, Lluís; Pérez Torres, Juan; Mihalache, Dumitru; Mazilu, Dumitru (Optical Society of American (OSA), 1999)
    Comunicació de congrés
    Accés obert
    Summary form only given. Quadratic solitons, that form through cascading in materials with second-order nonlinearities, are a topic of current intense investigation. Solitons have been observed in second harmonic generation ...
  • Ondas te en medios saturables no lineales 

    Pérez Torres, Juan; Torner Sabata, Lluís (1992)
    Text en actes de congrés
    Accés obert
    We show that universal V- b diagrams provide a powerful too! when analysing the stationary properties of the TE waves guided by a thin film bounded by a saturable nonlinear substrate or cladding. Relevant information for ...
  • Service provisioning and pricing methods in a multi-tenant cloud enabled RAN 

    Khodashenas, Pouria S.; Ruiz, Cristina; Ferrer Riera, Jordi; Fajardo, Jose Oscar; Taboada, Ianire; Blanco, Begoña; Liberal, Fidel; García Lloreda, J.; Pérez Romero, Jordi; Sallent Roig, José Oriol; Neokosmidis, Ioannis; Rokkas, Teodoros (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    The Cloud Enabled Small Cell (CESC) concept proposed in EU funded project SESAME has emerged as a promising solution to form a multi-tenant, multi-service architecture at the network edge according to 5G needs. It allows ...
  • Prosodic break prediction with RNNs 

    Pascual de la Puente, Santiago; Bonafonte Cávez, Antonio (Springer, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Prosodic breaks prediction from text is a fundamental task to obtain naturalness in text to speech applications. In this work we build a data-driven break predictor out of linguistic features like the Part of Speech (POS) ...
  • Impact of noisy annotators’ reliability in a crowdsourcing system performance 

    Cabrera Beán, Margarita Asuncion; Diaz Vilor, Carles; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Crowdsourcing is a powerful tool to harness citizen assessments in some complex decision tasks. When multiple annotators provide their individual labels a more reliable collective decision is obtained if the individual ...
  • Balanced tangential testing for the nonconforming discretization of the Electric-Field Integral Equation on open PeC surfaces 

    Úbeda Farré, Eduard; Sekulic, Ivan; Rius Casals, Juan Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Recent attention has been devoted to the development of nonconforming implementations of the Electric-Field Integral Equation (EFIE), which impose no continuity constraints in the expansion of the current between ...
  • Impact of amplitude calibration errors on SMOS global images 

    Durán Martínez, Israel; Corbella Sanahuja, Ignasi; Torres Torres, Francisco; Duffo Ubeda, Núria; Oliva, Roger; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Some of the artifacts observed in SMOS brightness temperature images are originated in an inconsistency between correlation and antenna temperature calibration errors, which produces a multiplicative bias that scales with ...
  • Mitigation of cross-polar antenna pattern errors in SMOS: simplified approach 

    Durán Martínez, Israel; Torres Torres, Francisco; Corbella Sanahuja, Ignasi; Duffo Ubeda, Núria; Lin, Wu; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper analyzes a simplified image reconstruction method that exclusively takes into account the dominant antenna pattern terms to model image inversion artifacts and mitigate SMOS polarimetric spatial bias over the ...
  • SMOS salinity retrievals enhancement in coastal areas by joint application of nodal sampling and corrected correlator efficiency 

    González Gambau, V.; Olmedo, Edson; Martinez, J.; Turiel Martínez, Antonio; Durán Martínez, Israel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This work is focused on the quality improvement of ESA's SMOS (Soil Moisture and Ocean Salinity) salinity retrievals, paying special attention to coastal regions. Two correction techniques have been applied to enhance the ...
  • On learning mobility patterns in cellular networks 

    Sánchez González, Juan; Pérez Romero, Jordi; Agustí Comes, Ramon; Sallent Roig, José Oriol (Springer, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper considers the use of clustering techniques to learn the mobility patterns existing in a cellular network. These patterns are materialized in a database of prototype trajectories obtained after having observed ...
