  • 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 ...
  • Cano Bastidas, Cristina; Bellalta, Boris; Sfairopoulou, Anna; Oliver Riera, Miquel; Barceló Vicens, Jaume (Springer, 2011)
    LWT-MAC is a new Low Power Listening MAC protocol for WSNs designed to rapidly react to instantaneous increases of the network load. It takes advantage of overhearing by waking up all nodes at the end of a transmission to ...
  • Amiri Nezhad, Maryam; Cerdà Alabern, Llorenç; Bellalta, Boris; Guerrero Zapata, Manel (Inderscience Enterprises Ltd, 2013)
    Channel assignment (CA) has been extensively researched for multi-radio wireless mesh networks (WMNs), but it is still very challenging when it comes to its implementation. In this paper we propose a semi-dynamic and ...
  • AlSkaif, Tarek; Guerrero Zapata, Manel; AlSkaif, Tarek; Bellalta, Boris; Nilsson, Anders (Springer, 2016)
    In microgrids, the integration of distributed energy resources (DERs) in the residential sector can improve power reliability, and potentially reduce power demands and carbon emissions. Improving the utilization of renewable ...
  • Meseguer, Pedro; Bouhmala, Noureddine; Bouzoubaa, Taoufik; Irgens, Morten; Sànchez Fibla, Martí (Springer, 2003)
    We summarize existing approaches to model and solve overconstrained problems. These problems are usually formulated as combinatorial optimization problems, and different specific and generic formalisms are discussed, ...
  • Bernardino Perez, Gabriel; Benkarim, Oualid M.; Sanz de la Garza, Maria; Prat Gonzàlez, Susanna; Sepúlveda Martínez, Álvaro; Crispi Brillas, Fàtima; Sitges, Marta; Butakoff, Constantine; De Craene, Mathieu; Bijnens, Bart; González Ballester, Miguel Ángel, 1973- (Elsevier, 2020)
    Statistical shape analysis is a powerful tool to assess organ morphologies and find shape changes associated to a particular disease. However, imbalance in confounding factors, such as demographics might invalidate the ...
  • 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 ...
  • Nikbakht, Rasoul; Mosayebi, Reza; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This letter proposes respective policies for uplink power control and downlink power allocation in cell-free wireless networks. Both policies rely only on large-scale quantities and are expressed in closed form, being ...
  • Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This paper formulates linear MMSE receivers that are both network- and user-centric for the uplink of cell-free wireless networks with centralized processing. Precisely, every user’s reception involves a distinct subset ...
  • Nuñez-Garcia, Marta; Bernardino Perez, Gabriel; Alarcón, Francisco; Caixal, Gala; Mont, Lluís; Camara, Oscar; Butakoff, Constantine (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Two-dimensional representation of 3D anatomical structures is a simple and intuitive way for analysing patient information across populations and image modalities. While cardiac ventricles, especially the left ventricle, ...
  • López Raventós, Álvaro; Bellalta, Boris (Elsevier, 2020)
    Enterprise Wireless Local Area Networks (WLANs) consist of multiple Access Points (APs) covering a given area. In these networks, interference is mitigated by allocating different channels to neighboring APs. Besides, ...
  • Pishtari, Gerti; Rodríguez-Triana, María Jesús; Sarmiento Márquez, Edna M.; Pérez Sanagustín, Maria del Mar; Ruiz Calleja, Adolfo; Santos Rodríguez, Patrícia; Prieto, Luis P.; Serrano Iglesias, Sergio; Väljataga, Terje (Wiley, 2020)
    Mobile and Ubiquitous Learning (m/u‐learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in ...
  • Cifra, Michal; Apollonio, Francesca; Liberti, Micaela; García Sánchez, Tomás; Mir, Lluis M. (Springer, 2020)
    Mechanisms of how electromagnetic (EM) field acts on biological systems are governed by the same physics regardless of the origin of the EM field (technological, atmospheric...), given that EM parameters are the same. We ...
