Recent Submissions

  • Bellalta, Boris; Faridi, Azadeh; Barceló Vicens, Jaume; Daza, Vanesa; Oliver Riera, Miquel (Elsevier, 2014)
    Multiuser Multi-Packet Transmission (MPT) from an Access Point (AP) equipped with multiple antennas to multiple single-antenna nodes can be achieved by exploiting the spatial dimension of the channel. In this paper we ...
  • Daza, Vanesa; Herranz, Javier; Sáez, Germán (Elsevier, 2009)
    Dutta and Mukhopadhyay have recently proposed some very efficient self-healing key distribution schemes with revocation. The parameters of these schemes contradict some results (lower bounds) presented by Blundo et al. In ...
  • Daza, Vanesa; Domingo-Ferrer, Josep; Sebe, Francesc; Viejo, Alexandre (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    Vehicular ad hoc networks (VANETs) allow vehicle-to-vehicle communication and, in particular, vehicle-generated announcements. Provided that the trustworthiness of such announcements can be guaranteed, they can greatly ...
  • Daza, Vanesa; Di Pietro, Roberto; Lombardi, Flavio; Signorini, Matteo (Elsevier, 2017)
    As services steadily migrate to the Cloud, the availability of an overarching identity framework has become a stringent need. Moreover, such an identity framework is now critical in the Internet of Things. To address this ...
  • Martí Juan, Gerard; Sanromà, Gerard; Piella Fenoy, Gemma (Elsevier, 2020)
    Background and Objectives: Recently, longitudinal studies of Alzheimer’s disease have gathered a substantial amount of neuroimaging data. New methods are needed to successfully leverage and distill meaningful information ...
  • Freire, Ismael T.; Moulin-Frier, Clement; Sánchez Fibla, Martí; Arsiwalla, Xerxes D.; Verschure, Paul F. M. J. (Public Library of Science (PLoS), 2020)
    What is the role of real-time control and learning in the formation of social conventions? To answer this question, we propose a computational model that matches human behavioral data in a social decision-making game that ...
  • Katina, Stanislav; Kelly, Brendan D.; Rojas, Mario A.; Sukno, Federico Mateo; McDermott, Aoibhinn; Hennessy, Robin J.; Lane, Abbie; Whelan, Paul F.; Bowman, Adrian W.; Waddington, John L. (Elsevier, 2020)
    As understanding of the genetics of bipolar disorder increases, controversy endures regarding whether the origins of this illness include early maldevelopment. Clarification would be facilitated by a ‘hard’ biological index ...
  • Balaguer-Ballester, Emili; Nogueira Mañas, Ramon; Abofalia, Juan M.; Moreno Bote, Rubén; Sanchez-Vives, Maria V. (Public Library of Science (PLoS), 2020)
    Shared neuronal variability has been shown to modulate cognitive processing. However, the relationship between shared variability and behavioral performance is heterogeneous and complex in frontal areas such as the ...
  • Sabri Abdalla, Aly; Powell, Keith; Geraci, Giovanni; Marojevic, Vuk (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Unmanned aerial vehicles (UAVs) are emerging as enablers for supporting many applications and services, such as precision agriculture, search and rescue, temporary network deployment or coverage extension, and security. ...
  • Oliva Rota, Mercè (SAGE Publications, 2020)
    This article explores ‘downward celebrity migration’, that is, when a celebrity enters a field that is less legitimate than their field of origin. It does so by studying the case of Lucía Etxebarria, a Spanish literary ...
  • Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2019)
    Multiple-exposure approaches for high dynamic range (HDR) image generation share a set of building assumptions: that color channels are independent and that the camera response function (CRF) remains constant while changing ...
  • Cyriac, Praveen; Canham, Trevor; Kane, David; Bertalmío, Marcelo (Springer, 2020)
    Many challenges that deal with processing of HDR material remain very much open for the film industry, whose extremely demanding quality standards are not met by existing automatic methods. Therefore, when dealing with HDR ...
  • Colomer, Marc; Sebastián-Gallés, Núria (Elsevier, 2020)
    Infants expect native and non-native speech to communicate, i.e. to transfer information between third-parties. Here, we explored if infants understand that communication depends on the use of shared conventional systems ...
  • Celma Miralles, Alexandre, 1991-; Toro Soto, Juan Manuel, 1976- (Springer, 2020)
    The musical motives of a song emerge from the temporal arrangement of discrete tones. These tones normally have few durational values, and are organized in structured groups to create metrical patterns. In the present study ...
  • Bogdanov, Dmitry; Wack, Nicolas; Gómez Gutiérrez, Emilia, 1975-; Gulati, Sankalp; Herrera Boyer, Perfecto, 1964-; Mayor, Oscar; Roma Trepat, Gerard; Salamon, Justin; Zapata González, José Ricardo; Serra, Xavier (ACM Association for Computer Machinery, 2014)
    Over the last decade, audio analysis has become afield of active research in academic and engineeringworlds. It refers to the extraction of information andmeaning from audio signals for analysis, ...
  • Raad, Lara; Oliver Parera, Maria; Ballester, Coloma; Haro Ortega, Gloria; Meinhardt Llopis, Enric (IPOL, 2020)
    This work describes two anisotropic optical flow inpainting algorithms. The first one recovers the missing flow values using the Absolutely Minimizing Lipschitz Extension partial differential equation (also called infinity ...
  • Roma Trepat, Gerard; Herrera Boyer, Perfecto, 1964-; Nogueira, Waldo (Springer, 2018)
    Recognition of environmental sound is usually based on two main architectures, depending on whether the model is trained with frame-level features or with aggregated descriptions of acoustic scenes or events. The former ...
  • Accuosto, Pablo; Saggion, Horacio (Elsevier, 2020)
    Argument mining consists in the automatic identification of argumentative structures in texts. In this work we leverage existing discourse-level annotations to facilitate the identification of argumentative components and ...
  • Mercadal, Borja; Vicente, Rubén; Ivorra Cano, Antoni, 1974- (Elsevier, 2020)
    Pulsed radiofrequency (PRF) treatments for chronic pain consist in the delivery of a train of sinusoidal electric bursts to the targeted nerve. Despite numerous clinical evidence of its efficiency, the mechanism of action ...
  • AbuRa’ed, Ahmed; Saggion, Horacio; Shvets, Alexander; Bravo Serrano, Àlex, 1984- (Springer, 2020)
    Related work sections or literature reviews are an essential part of every scientific article being crucial for paper reviewing and assessment. However, writing a good related work section is an activity which requires ...
