  • Colombaro, Ivano; Giusti, Andrea; Mentrelli, Andrea (Springer, 2023)
    We investigate the specific attenuation factor for the Bessel models of viscoelasticity. We find that the quality factor for this class can be expressed in terms of Kelvin functions and that its asymptotic behaviours confirm ...
  • Galí Pérez, Olga; Sayis, Batuhan; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2021)
    The present study analyses the effectiveness of a mixed reality (MR) face-to-face full-body system to foster social interaction behaviors (SIBs) in a child with ASC and a play partner, a child without ASC (non-ASC). An MR ...
  • Andrzejak, Ralph Gregor; Espinoso Palacín, Anaïs (American Institute of Physics (AIP), 2023)
    Different across-layer synchronization types of chimera states in multilayer networks have been discovered recently. We investigate possible relations between them, for example, if the onset of some synchronization type ...
  • Diaz-Vilor, Carles; Lozano Solsona, Angel; Jafarkhani, Hamid (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Recently, cell-free (CF) architectures, in which every user can potentially communicate with every base station, have received a lot of attention. This paper considers the uplink of fully and partially centralized CF ...
  • Guardiola, Marta; Buitrago, Santiago; Fernández-Esparrach, Gloria; O’Callaghan, Joan M.; Romeu, Jordi; Cuatrecasas, Miriam; Córdova, Henry; González Ballester, Miguel Ángel, 1973-; Camara, Oscar (American Association of Physicists in Medicine (AAPM), 2018)
    Purpose: Colorectal cancer is highly preventable by detecting and removing polyps, which are the precursors. Currently, the most accurate test is colonoscopy, but still misses 22% of polyps due to visualization limitations. ...
  • Gómez Balduz, Olga; Okumura, Kenichi; Honjo, Osami; Sun, Mei; Ishii, Ryo; Bijnens, Bart; Friedberg, Mark K. (American Psychological Association (APA), 2018)
    The objective of the present study was to investigate mechanisms of heart rate (HR) reduction on biventricular function and interactions in experimental pulmonary arterial hypertension (PAH). We compared cardiac cycle ...
  • Martinez, Alfonso; Font Segura, Josep; Colombaro, Ivano (Springer, 2021)
    This paper characterizes the symmetric rank-2 stress–energy–momentum tensor associated with fields whose Lagrangian densities are expressed as the dot product of two multivector fields, e.g., scalar or gauge fields, in ...
  • Caselles, Vicente; Sapiro, Guillermo; Solé, Andrés; Ballester, Coloma (SIAM (Society for Industrial and Applied Mathematics), 2006)
    A geometric representation for images is studied in this work. This is based on two complementary geometric structures for the topographic representation of an image. The first one computes a description of the Morse ...
  • Valls, Victor; Sánchez, José Luis; Cano Bastidas, Cristina; Bellalta, Boris; Oliver Riera, Miquel (Elsevier, 2013)
    The paper presents two mechanisms for designing an on-demand, reliable and efficient collection protocol for Wireless Sensor Networks. The former is the Bidirectional Link Quality Estimation, which allows nodes to easily ...
  • Law, Mark; Russo, Alessandra; Bertino, Elisa; Broda, Krysia; Lobo, Jorge (Association for the Advancement of Artificial Intelligence (AAAI), 2020)
    Inductive Logic Programming (ILP) systems aim to find a set of logical rules, called a hypothesis, that explain a set of examples. In cases where many such hypotheses exist, ILP systems often bias towards shorter solutions, ...
  • Fedorov, Vadim; Arias Martínez, Pablo; Facciolo Furlan, Gabriele; Ballester, Coloma (Springer, 2016)
    Patch-based approaches are used in state-of-the-art methods for image inpainting. This paper presents a new method for exemplar-based image inpainting using transformed patches. The transformation is determined for each ...
  • Crespo Bojorque, Paola, 1985-; Toro Soto, Juan Manuel, 1976- (American Psychological Association (APA), 2016)
    Traditionally, physical features in musical chords have been proposed to be at the root of consonance perception. Alternatively, recent studies suggest that different types of experience modulate some perceptual foundations ...
  • Ballester, Coloma; Caselles, Vicente; Igual, Laura; Verdera, Joan; Rougé, Bernard (Springer, 2006)
    We propose an algorithm to increase the resolution of multispectral satellite images knowing the panchromatic image at high resolution and the spectral channels at lower resolution. Our algorithm is based on the assumption ...
  • Ballester, Coloma; Caselles, Vicente; Igual, Laura; Garrido, Luís (Springer, 2007)
    This paper discusses the interest of the Tree of Shapes of an image as a region oriented image representation. The Tree of Shapes offers a compact and structured representation of the family of level lines of an image. ...
  • Cravotta, Alice; Busà, Maria Grazia; Prieto Vives, Pilar, 1965- (American Speech-Language-Hearing Association, 2019)
    Purpose: Previous studies have investigated the effects of the inability to produce hand gestures on speakers' prosodic features of speech; however, the potential effects of encouraging speakers to gesture have received ...
  • Zapata González, José Ricardo; Davies, Matthew E. P.; Gómez Gutiérrez, Emilia, 1975- (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A recent trend in the field of beat tracking for musical audio signals has been to explore techniques for measuring the level of agreement and disagreement between a committee of beat tracking algorithms. By using beat ...
  • Cárcamo Ulloa, Luis; Cárdenas Neira, Camila; Scheihing-García, Eliana; Sáez-Trumper, Diego; Vernier, Matthieu; Blaña-Romero, Carlos (MDPI, 2023)
    Citizens get informed, on a daily basis, from social networks in general and from the media in particular. Accordingly, the media are increasingly expressing their concern about phenomena related to disinformation. This ...

    Small and medium enterprises are significantly hampered by cyber-threats as they have inherently limited skills and financial capacities to anticipate, prevent, and handle security incidents. The EU-funded PALANTIR project ...
  • Hernández Leo, Davinia; Amarasinghe, Ishari; Beardsley, Marc; Hakami, Eyad; Ruiz Garcia, Aurelio; Santos Rodríguez, Patrícia (SpringerNature, 2023)
    This chapter unfolds some elements of responsible research in the educational technology field and provides examples about how these elements have been considered in initiatives by the Interactive and Distributed Technologies ...
  • Michaelides, Michael; Adame, Toni; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    The Industrial Internet of Things (IoT) has gained a lot of momentum thanks to the introduction of Time Slotted Channel Hopping (TSCH) in IEEE 802.15.4. At last, we can enjoy collision-free, low-latency wireless communication ...
