    Technology enhanced learning (TEL) research connects Learning Sciences, Educational Psychology, and Computer Science, in order to investigate interventions based on digital technologies in education and training settings. ...
  • Di Pietro, Roberto; Oligeri, Gabriele; Salleras Soler, Xavier; Signorini, Matteo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    In this paper we propose N-Guard: a portable, effective, and efficient solution to thwart contactless skimming of NFC cards. Our solution enables an NFC-compliant smartphone to protect the user's cards, preventing the ...
  • Di Pietro, Roberto; Salleras Soler, Xavier; Signorini, Matteo; Waisbard, Erez (ACM Association for Computer Machinery, 2018)
    One of the biggest challenges for the Internet of Things (IoT) is to bridge the currently fragmented trust domains. The traditional PKI model relies on a common root of trust and does not fit well with the heterogeneous ...
  • Salleras Soler, Xavier; Daza, Vanesa (Hindawi, 2020)
    5G communications proposed significant improvements over 4G in terms of efficiency and security. Among these novelties, the 5G network slicing seems to have a prominent role: deploy multiple virtual network slices, each ...
  • Daza, Vanesa; Salleras Soler, Xavier (SciTePress. Science and Technology Publications, 2019)
    Since Remote Keyless Entry (RKE) systems started to be widely used, several vulnerabilities in their protocols have been found. Attacks such as jamming-and-replay attacks and relay attacks are still effective against most ...
  • Truong, Kien T.; Lozano Solsona, Angel; Heath, R. W., Jr. (UNLISTED PUBLISHERVDE Verlag, 2014)
    Massive multiple-input multiple-output (MIMO) communication promises the full potential of MIMO communication realized through the deployment of hundreds of antennas at each base station. Accurate channel state information ...
  • Triay, Joan; Minguillón, Julià; Sancho Vinuesa, Teresa; Daza, Vanesa (CEUR Workshop Proceedings, 2016)
    The huge amount of gathered data in a MOOC allows providing professors and course managers with insightful information about real course usage and consumption. The main aim of this work is to explore how efficient ...
  • Llorach, Gerard; Agenjo, Javier; Blat, Josep; Sayago Barrantes, Sergio (Springer, 2019)
    Within Human-Computer Interaction, there has recently been an important turn to embodied and voice-based interaction. In this chapter, we discuss our ongoing research on building online Embodied Conversational Agents (ECAs), ...
  • Sukno, Federico Mateo; Aspandi, Decky; Martínez, Oriol; Sukno, Federico Mateo; Binefa i Valls, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Human facial tracking is an important task in computer vision, which has recently lost pace compared to other facial analysis tasks. The majority of current available tracker possess two major limitations: their little use ...
  • Carrascosa Zamacois, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    WiFi densification leads to the existence of multiple overlapping coverage areas, which allows user stations (STAs) to choose between different Access Points (APs). The standard WiFi association method makes the STAs select ...
  • Martorell Domínguez, Agustín; Gómez Gutiérrez, Emilia, 1975- (Taylor & Francis, 2015)
    This work presents a systematic methodology for set-class surface analysis using temporal multi-scale techniques. The method extracts the set-class content of all the possible temporal segments, addressing the representational ...
  • Kosta, Katerina; Ramírez, Rafael,1966-; Bandtlow, Oscar F.; Chew, Elaine (Taylor & Francis, 2016)
    Loudness variation is one of the foremost tools for expressivity in music performance. Loudness is frequently notated as dynamic markings such as p (piano, meaning soft) or f (forte, meaning loud). While dynamic markings ...
  • Serra, Xavier (Taylor & Francis (Routledge), 1997)
    When generating musical sound on a digital computer, it is important to have a good model whose parameters provide a rich source of meaningful sound transformations. Three basic model types are in prevalent use today for ...
  • Kringelbach, Morten L.; Deco, Gustavo (Elsevier, 2020)
    Within the field of computational neuroscience there are great expectations of finding new ways to rebalance the complex dynamic system of the human brain through controlled pharmacological or electromagnetic perturbation. ...
  • Héroux, Isabelle; Giraldo, Sergio; Ramírez, Rafael,1966-; Dubé, Francis; Creech, Andrea; Thouin-Poppe, Louis-Édouard (Frontiers, 2020)
    Philosophers, composers, and musicians have long argued whether instrumental music finds meaning in its formal structure and musical content (Hanslick, 1986) or through reference to extra-musical elements, like narratives, ...
  • Eladly, Ahmed; Del Valle, Jaume; Minguillon, Jesus; Mercadal, Borja; Becerra Fajardo, Laura; Navarro, Xavier; Ivorra Cano, Antoni, 1974- (IOP Publishing Ltd., 2020)
    Objective. It is known that multi-site interleaved stimulation generates less muscle fatigue compared to single-site synchronous stimulation. However, in the limited number of studies in which intramuscular electrodes were ...
  • Korzeniowski, Filip; Nieto Caballero, Oriol; McCallum, Matthew C.; Won, Minz; Oramas, Sergio; Schmidt, Erik M. (International Society for Music Information Retrieval (ISMIR), 2020)
    The mood of a song is a highly relevant feature for exploration and recommendation in large collections of music. These collections tend to require automatic methods for predicting such moods. In this work, we show that ...
  • Doras, Guillaume; Yesiler, Furkan; Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975-; Peeters, Geoffroy (International Society for Music Information Retrieval (ISMIR), 2020)
    Recent works have addressed the automatic cover detection problem from a metric learning perspective. They employ different input representations, aiming to exploit melodic or harmonic characteristics of songs and yield ...
  • Serrà Julià, Joan; Yesiler, Furkan; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2020)
    Version identification systems aim to detect different renditions of the same underlying musical composition (loosely called cover songs). By learning to encode entire recordings into plain vector embeddings, recent systems ...
  • Külebi, Baybars; Öktem, Alp; Peiró Lilja, Àlex; Pascual, Santiago; Farrús, Mireia (International Speech Communication Association (ISCA), 2020)
    We present Catotron, a neural network-based open-source speech synthesis system in Catalan. Catotron consists of a sequence-to-sequence model trained with two small opensource datasets based on semi-spontaneous and read ...
