  • Efficient analysis of thick curved metal sheets 

    Úbeda Farré, Eduard; Rius Casals, Juan Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    The scattering analysis of perfectly conducting plates with the method-of-moment discretization of the Electric-Field Integral Equation has been traditionally carried out according to the thin-sheet approximation, which ...
  • Fourier analysis of submillimeter-wave scattering from the human cornea 

    Zarrinkhat, Faezeh; Lamberg, Joel; Tamminen, Aleksi; Baggio, Mariangela; Ala-Laurinaho, Juha; Khaled, Elsayed E. M.; Rius Casals, Juan Manuel; Romeu Robert, Jordi; Taylor, Zachary (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    Wave scattering from a human cornea illuminated with a submillimeter-wave Gaussian beam is explored with Fourier analysis. This new approach enabled us to investigate the cornea as a coated sphere rather than a homogenized ...
  • Multilingual machine translation: Closing the gap between shared and language-specific encoder-decoders 

    Escolano Peinado, Carlos; Ruiz Costa-Jussà, Marta; Rodríguez Fonollosa, José Adrián; Artetxe Zurutuza, Mikel (Association for Computational Linguistics, 2021)
    Conference lecture
    Open Access
    State-of-the-art multilingual machine translation relies on a universal encoder-decoder, which requires retraining the entire system to add new languages. In this paper, we propose an alternative approach that is based on ...
  • Estimation of information in parallel Gaussian channels via model order selection 

    López Molina, Carlos Alejandro; Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference lecture
    Open Access
    We study the problem of estimating the overall mutual information in M independent parallel discrete-time memory-less Gaussian channels from N independent data sample pairs per channel (inputs and outputs). We focus on the ...
  • RESim - Automated detection of duplicated requirements in software engineering projects 

    Motger de la Encarnación, Joaquim; Palomares Bonache, Cristina; Marco Gómez, Jordi (CEUR-WS.org, 2020)
    Conference report
    Open Access
    Collaborative software development experience in recent years proves that the management of large sets of requirements has become a critical issue. Among the main problems of requirements engineering, the detection and ...
  • Experimental assessment of SDN-enabled sliceable OPSquare data center network with deterministic QoS 

    Xue, Xuwei; Wang, Fu; Agraz Bujan, Fernando; Pagès Cruz, Albert; Yan, Fulong; Spadaro, Salvatore; Calabretta, Nicola (2019)
    Conference report
    Restricted access - publisher's policy
    An SDN-enabled sliceable DCN with deterministic QoS guarantees is experimentally assessed. Flow priorities are dynamically assigned to each network-slice to prevent statistical latency and packet-loss due to packet ...
  • Machine-learning based traffic forecasting for resource management in C-RAN 

    Guerra Gómez, Rolando; Ruiz Boqué, Sílvia; García Lozano, Mario; Olmos Bonafé, Juan José (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report

    The assumption of a fixed computational capacityat the Baseband Unit (BBU) pools in a Cloud Radio Access Network (C-RAN) deployment results in underutilized resourcesor unsatisfied users depending on ...
  • Prediction of the optimal phase shift between control signals in dual-input power amplifiers 

    Guillena Berenguer, Estefanía; Li, Wantao; Gilabert Pinal, Pere Lluís; Montoro López, Gabriel
    Conference report
    Restricted access - publisher's policy
    This paper evaluates the effect of the phase shift between the two control signals in a dual-input load modulated balanced amplifier (LMBA). While the drain efficiency of the LMBA is not significantly affected by the phase ...
  • An UWB Tapered Slot Vivaldi Antenna (TSA) with improved characterestics 

    Akazzim, Youness; Kanjaa, Mohammed; El Mrabet, Otman; Jofre Roca, Lluís; Essaaidi, Mohamed (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    In this paper, an UWB Tapered Slot Vivaldi Antenna (TSA) is presented. The proposed TSA is optimized in order to increase the bandwidth and ensure a good impedance matching at low and bandwidth frequencies while respecting ...
  • The flexible microwave payload -2: design, implementation, and optimization of a GNSS-R and radiometry processor for cubesat-based earth observation missions 

    Muñoz Martin, Joan Francesc; Fernandez Capon, Lara Pilar; Ruiz De Azúa Ortega, Juan Adrián; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Restricted access - publisher's policy
    The Flexible Microwave Payload 2 (FMPL-2) is a Remote Sensing payload carried on board 3 Cat-5/A, one of the two 6-unit CubeSats of the FSSCat mission. FMPL-2 is a payload based on a Software Defined Radio (SDR), integrating ...
  • Precise orbit observation techniques for geosynchronous synthetic aperture radar (GEOSAR) 

    Nicolás Álvarez, Jorge; Broquetas Ibars, Antoni; Aguasca Solé, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Restricted access - publisher's policy
    The orbit accuracy requirements for a Geosynchronous Synthetic Aperture Radar (GEOSAR) are studied. Compared to telecommunication GEO satellites' station keeping needs, focusing the GEOSAR synthetic aperture demands a more ...
  • Refining the methodology to correct the faraday rotation angle from SMOS measurements 

    Rubino, Roselena; Duffo Ubeda, Núria; González Gambau, Verónica; Corbella Sanahuja, Ignasi; Durán Martínez, Israel; Torres Torres, Francisco; Martín Neira, Manuel
    Conference report
    Restricted access - publisher's policy
    In this work, a refined methodology to correct the Faraday Rotation angle (FRA) for the SMOS mission is proposed. The method is based on calculating the FRA using the SMOS full-pol radiometric data to obtain VTEC maps ...
