  • Farrús, Mireia (Universitat de Barcelona, 2011)
    La biometria té com a objectiu el reconeixement de persones mitjançant un o més identificadors biomètrics com la veu, la cara o les empremtes dactilars, entre d'altres. Gràcies a la bona acceptació social i el poc intrusisme ...
  • Farrús, Mireia; Noguera, Ingrid; Santanach, Francesc; Moré, Quim; López Pérez, Cristina; Appel, Christine (Col·legi Oficial de Bibliotecaris-Documentalistes de Catalunya, 2011)
    Durant les últimes dècades, en un context en què impera la influència de les TIC, el model de l'ensenyament universitari ha canviat radicalment. Paral·lelament, els rols de l'estudiant i del professor també s'han vist ...
  • Andrzejak, Ralph Gregor; Laiou, Petroula (American Physical Society, 2017)
    The understanding of interacting dynamics is important for the characterization of real-world/nnetworks. In general real-world networks are heterogeneous in the sense that each node of the/nnetwork is a dynamics with di ...
  • Yeonan-Kim, Jihyun; Bertalmío, Marcelo (Public Library of Science (PLoS), 2016)
    Retinal lateral inhibition is one of the conventional efficient coding mechanisms in the visual system that is produced by interneurons that pool signals over a neighborhood of presynaptic feedforward cells and send ...
  • Ballesteros, Miguel; Bohnet, Bernd; Mille, Simon; Wanner, Leo (Cambridge University Press, 2016)
    ‘Deep-syntactic’ dependency structures that capture the argumentative, attributive and co-/nordinative relations between full words of a sentence have a great potential for a number/nof NLP-applications. The abstraction ...
  • Lord, Louis-David; Expert, Paul; Fernandes, Henrique M.; Giovanni, Petri; Van Hartevelt, Tim J.; Vaccarino, Francesco; Deco, Gustavo; Turkheimer, Federico; Kringelbach, Morten L. (Frontiers, 2016)
    In recent years, the application of network analysis to neuroimaging data has provided useful insights about the brain's functional and structural organization in both health and disease. This has proven a significant ...
  • Zamir, Syed Wagas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Gamut mapping transforms the colors of an input/nimage to the colors of a target device so as to exploit the full/npotential of the rendering device in terms of color rendition. In/nthis paper we present spatial gamut ...
  • Basart i Muñoz, Josep M.; Farrús, Mireia; Serra, Montse (Elsevier, 2015)
    This paper is about the intersection of three related areas: ethics, gender and the field of engineering. It is important to focus on the attitudes and values woven through this intersection because they become essential ...
  • Montbrió, Ernest, 1974-; Pazó, Diego (American Physical Society, 2016)
    Collective chaos is shown to emerge, via a period-doubling cascade, from quasiperiodic partial synchronization in a population of identical inhibitory neurons with delayed global coupling. This system is thoroughly ...
  • Andrzejak, Ralph Gregor; Rummel, Christian; Mormann, Florian; Schindler, Kaspar A. (Nature Publishing Group, 2016)
    Conceptually and structurally simple mathematical models of coupled oscillator networks can show a rich variety of complex dynamics, providing fundamental insights into many real-world phenomena.A recent and not yet fully ...
  • Samardzija, Dragan; Lozano Solsona, Angel; Papadias, Constantinos B (Hindawi, 2005)
    In single-user MIMO communication, the first-order throughput scaling is determined by the smallest of the number of transmit and receive antennas. This typically renders terminals the constraining bottleneck. In a multiuser ...
  • Chung, Seong Taek; Lozano Solsona, Angel; Huang, Howard C.; Sutivong, Arak; Cioffi, John M. (Hindawi, 2004)
    This paper presents an extension of the vertical Bell Laboratories Layered Space-Time (V-BLAST) architecture in which the closed-loop multiple-input multiple-output (MIMO) capacity can be approached with conventional scalar ...
  • Mungara, Ratheesh K.; Zhang, Xinchen; Lozano Solsona, Angel; Heath, Robert W. (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Device-to-device (D2D) communication allows serving local wireless traffic bypassing the system’s/ninfrastructure. One way to control the interference in D2D networks is to carefully channelize/ntransmissions. This paper ...
  • Schedl, Markus; Gómez Gutiérrez, Emilia, 1975-; Urbano, Julián (Now Publishers Inc., 2014)
    We provide a survey of the field of Music Information Retrieval (MIR), in particular paying attention to latest developments, such as semantic auto-tagging and user-centric retrieval and recommendation approaches. We first ...
  • Rubio Ballester, Belén; Maier, Martina; San Segundo Mozo, Rosa María; Castañeda, Victoria; Duff, Armin; Verschure, Paul F. M. J. (BioMed Central, 2016)
    Background: After stroke, patients who suffer from hemiparesis tend to suppress the use of the affected extremity, a condition called learned non-use. Consequently, the lack of training may lead to the progressive deterioration ...
  • Becerra Fajardo, Laura; Schmidbauer, Marieluise; Ivorra Cano, Antoni, 1974- (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Existing implantable stimulators use powering approaches that result in stiff and bulky systems or result in systems incapable of producing the current magnitudes required for neuromuscular stimulation. This hampers their ...
  • Mercadal Cavaller, Borja; Vernier, P. Thomas; Ivorra Cano, Antoni, 1974- (Springer, 2016)
    It is widely accepted that electroporation occurs when the cell transmembrane voltage induced by an external applied electric field reaches a threshold. Under this assumption, in order to trigger electroporation in a ...
  • Schmitz, Judith, 1984-; Díaz Menéndez, Begoña, 1979-; Sebastián Gallés, Núria (Taylor & Francis (Routledge), 2016)
    Previous studies showed that manipulating the speech production system influenced speech perception. This influence was mediated by task difficulty, listening conditions, and attention. In the present study we investigated ...
  • Overvliet, Krista E.; Karana, Elvin; Soto-Faraco, Salvador, 1970- (Elsevier, 2016)
    In many daily contexts, we prefer natural ‘materials’ over un-natural ones. Textiles embodied in garments that are worn on the body all day, or in bed sheets slept under every night touch us literally, on a daily basis. ...
  • ten Oever, Sanne; Romei, Vincenzo; van Atteveldt, Nienke; Soto-Faraco, Salvador, 1970-; Murray, Micah M.; Matusz, Pawel J. (Springer, 2016)
    Our understanding of how perception operates in real-world environments has been substantially advanced by studying both multisensory processes and “top-down” control processes influencing sensory processing via activity ...
