  • AlSkaif, Tarek; Guerrero Zapata, Manel; Bellalta, Boris (Elsevier, 2015)
    In the area of Wireless Sensor Networks (WSNs), improving energy efficiency and network lifetime is one of the most important and challenging issues. Most of the considered WSNs are formed by nodes with limited resources, ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Emerging display technologies are able to produce images with a much wider color gamut than those of conventional distribution gamuts for cinema and TV, creating an opportunity for the development of gamut extension ...
  • Vazquez-Corral, Javier; Bertalmío, Marcelo (Society for Imaging Science and Technology, 2017)
    Visual attention retargeting attempts to modify an image such that the viewer’s attention is directed to specific regions. Goals include highlighting a particular object or hiding possible problems in the image. In this ...
  • Zamir, Syed Waqas; 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 ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Society for Imaging Science and Technology, 2017)
  • Sarnago, Héctor; Burdío, José Miguel; García Sánchez, Tomás; Mir, Lluis M.; Álvarez Gariburo, Ignacio; Lucía, Óscar (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Biomedical applications often require high-performance power supplies for diagnosis and treatment systems. In particular, modern electroporation techniques for cancer treatment require high-voltage generators with versatile ...
  • Sanchis, Laura; Sanz de la Garza, Maria; Bijnens, Bart; Giraldeau, Geneviève; Grazioli, Gonzalo; Marin, Josefa; Gabrielli, Luigi; Montserrat, Silvia; Sitges, Marta (Taylor & Francis, 2017)
    Background: High-intensity training has been associated with atrial remodelling and arrhythmias in men. Our purpose was to analyse atrial performance in female endurance athletes, compared to male athletes and controls. ...
  • Colombaro, Ivano; Font Segura, Josep; Martinez, Alfonso (Springer, 2020)
    This paper presents an exterior-algebra generalization of electromagnetic fields and source currents as multivectors of grades r and r−1, respectively, in a flat space-time with n space and k time dimensions. Formulas for ...
  • Lai, I-Wei; Shih, Jhih-Wei; Chen, Kwang-Cheng; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Opportunistic links are emerging as a novel technology for state-of-the-art wireless networks, such as cognitive radio networks, energy-harvesting networks, and low-latency vehicular networks. To increase the reliability ...
  • Andrzejak, Ralph Gregor; Ruzzene, Giulia; Malvestio, Irene (American Institute of Physics (AIP), 2017)
    Networks of coupled oscillators in chimera states are characterized by an intriguing interplay of synchronous and asynchronous motion. While chimera states were initially discovered in mathematical model systems, there is ...
  • Aragón, Pablo; Gómez, Vicenç; García, David; Kaltenbrunner, Andreas (SpringerOpen, 2017)
    Online discussion in form of written comments is a core component of many social media platforms. It has attracted increasing attention from academia, mainly because theories from social sciences can be explored at an ...
  • Beg, Abul Hashem; Islam, Md Zahidul; Estivill-Castro, Vladimir (Elsevier, 2016)
    Many popular clustering techniques including K-means require various user inputs such as the number of clusters k, which can often be very difficult for a user to guess in advance. Moreover, existing techniques like K-means ...
  • Ferradans Ramonde, Sira; Bertalmío, Marcelo; Caselles, Vicente (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Demosaicking is a particular case of interpolation problems where, from a scalar image in which each pixel has either the red, the green or the blue component, we want to interpolate the full-color image. State-of-the-art ...
  • Vohryzek, Jakub; Deco, Gustavo; Cessac, Bruno; Kringelbach, Morten L.; Cabral, Joana R. B. (Frontiers, 2020)
    Functionally relevant network patterns form transiently in brain activity during rest, where a given subset of brain areas exhibits temporally synchronized BOLD signals. To adequately assess the biophysical mechanisms ...
  • Dutra, T. B.; Marques, Ricardo; Cavalcante‐Neto, J.B.; Vidal, C. A.; Pettré, J. (Wiley, 2017)
    Most recent crowd simulation algorithms equip agents with a synthetic vision component for steering. They offer promising perspectives through a more realistic simulation of the way humans navigate according to their ...
  • Bettinardi, Ruggero G.; Tort-Colet, Núria; Ruiz Mejias, Marcel; Sanchez-Vives, Maria V.; Deco, Gustavo (Elsevier, 2015)
    Intrinsic brain activity is characterized by the presence of highly structured networks of correlated fluctuations between different regions of the brain. Such networks encompass different functions, whose properties are ...
  • Munteanu, Cristian R.; Aguiar Pulido, Vanessa; Freire, Ana; Martínez Romero, Marcos; Porto Pazos, Ana B.; Pereira, Javier; Dorado, Julian (Bentham Science Publishers, 2015)
    The complex information encoded into the element connectivity of a system gives rise to the possibility of graphical processing of divisible systems by using the Graph theory. An application in this sense is the quantitative ...
  • Melero Merino, Javier; Hernández Leo, Davinia; Manathunga, Kalpani (Elsevier, 2015)
    Within the field of Game-based Learning (GBL) location-based games are based on pervasive and mobile learning to allow the creation of in situ learning activities considering gamification mechanisms. In these learning ...
  • Ikumi Montserrat, Nara, 1986-; Soto-Faraco, Salvador, 1970- (Frontiers, 2017)
    Perception in multi-sensory environments involves both grouping and segregation of events across sensory modalities. Temporal coincidence between events is considered a strong cue to resolve multisensory perception. However, ...
