  • Biau, Emmanuel, 1985-; Morís Fernández, Luis, 1982-; Holle, Henning; Avila, César; Soto-Faraco, Salvador, 1970- (Elsevier, 2016)
    During public addresses, speakers accompany their discourse with spontaneous hand gestures (beats) that are tightly synchronized with the prosodic contour of the discourse. It has been proposed that speech and beat gestures ...
  • Manathunga, Kalpani; Hernández Leo, Davinia (International Forum of Educational Technology & Society, 2015)
    There is a growing interest in understanding to what extent innovative educational technologies can be used to/nsupport massive courses. Collaboration is one of the main desired elements in massive learning actions/ninvolving ...
  • Derkach, Dmytro; Ruiz Ovejero, Adrià; Sukno, Federico Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    In this paper we present a system that is able to estimate head pose using only depth information from consumer RGB-D cameras such as Kinect 2. In contrast to most approaches addressing this problem, we do not rely on ...
  • Ortigosa, Núria; Rodriguez López, Mérida; Bailón, Raquel; Sarvari, Sebastian Imre; Sitges, Marta; Gratacós Solsona, Eduard; Bijnens, Bart; Crispi Brillas, Fàtima; Laguna, Pablo (Elsevier, 2016)
    Intrauterine Growth Restriction (IUGR) and premature birth are associated with higher risk of cardiovascular diseases throughout adulthood. The aim of this study was to evaluate the influence of these factors in ventricular ...
  • Hernández Leo, Davinia; Agostinho, Shirley; Beardsley, Marc; Bennet, Sue; Lockyer, Lori (IATED, 2017)
    Designing learning experiences for students is a key responsibility of teachers. This involves designing stimulating and engaging tasks, selecting and creating appropriate resources, and deciding how best to support students ...
  • Bonet, Blai; Geffner, Héctor (Elsevier, 2008)
    The automatic derivation of heuristic functions for guiding the search for plans is a fundamental technique in planning. The type of heuristics that have been considered so far, however, deal only with simple planning ...
  • Segovia-Aguas, Javier; Jiménez, Sergio; Jonsson, Anders, 1973- (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    Finite State Controllers (FSCs) are an effective way/nto represent sequential plans compactly. By imposing/nappropriate conditions on transitions, FSCs/ncan also represent generalized plans that solve a/nrange of planning ...
  • Gil Rodríguez, Raquel; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    In this paper we present a simple and affordable method to generate high quality video from a high dynamic range scene. It is performed without utilizing extra lighting, neither alternating exposures, nor operating with ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Benton, DM (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This article proposes a frequency agile antenna whose operating frequency band can be switched. The design is based on a Vivaldi antenna. High-performance radio-frequency microelectromechanical system (RF-MEMS) switches ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Brittan, P. (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A frequency agile Vivaldi antenna whose operating frequency band can be switched is pro- posed. High-performance radio-frequency micro- electromechanical system (RF-MEMS) switches al- low tuning of the operational band ...
  • Montesinos, P.; Abascal, Juan F.P.J.; Chamorro Servent, Judit; Chavarrías, Cristina; Benito, M.; Vaquero, Juan J.; Desco, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Dynamic cardiac magnetic resonance imaging in small animals is an important tool in the study of cardiovascular diseases. The reduction of the long acquisition times required for cardiovascular applications is crucial ...
  • Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We analyze multiuser detection under the assumption that the number of users accessing the channel is unknown by the receiver. Our main goal is to determine the performance loss caused by the need for estimating the ...
  • Lozano Solsona, Angel; Tulino, Antonia M.; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    The analysis of the multiantenna capacity in the high-SNR regime has hitherto focused on the high-SNR slope (or maximum multiplexing gain), which quantifies the multiplicative /nincrease as function of the number of antennas. ...
  • Kaplan, Raphael; Adhikari, Mohit H.; Hindriks, Rikkert; Mantini, Dante; Murayama, Yusuke (Elsevier, 2016)
    The default mode network (DMN) is a commonly observed resting-state network (RSN) that includes medial temporal, parietal, and prefrontal regions involved in episodic memory [1-3]. The behavioral relevance of endogenous ...
  • Farrús, Mireia; Ejarque, Pascual; Temko, Andrey; Hernando, Javier (Springer, 2007)
    It has been shown that prosody helps to improve voice spectrum based speaker recognition systems. Therefore, prosodic features can also be used in multimodal person verification in order to achieve better results. In this ...
  • Rolls, Edmund T; Dempere-Marco, Laura; Deco, Gustavo (Public Library of Science, 2013)
    Human short term memory has a capacity of several items maintained simultaneously. We show how the number of short term memory representations that an attractor network modeling a cortical local network can simultaneously ...
  • Martin, Clara D.; García, Xavier, 1967-; Potter, Douglas; Melinger, Alissa; Costa, Albert, 1970- (Taylor & Francis (Routledge), 2016)
    Native speakers with different linguistic backgrounds differ in their usage of language, and particularly in their vocabulary. For instance, British natives would use the word "holiday" when American natives would prefer ...
  • Bereby‐Meyer, Yoella; Hayakawa, Sayuri; Shalvi, Shaul; Corey, Joanna Darrow, 1986-; Costa, Albert, 1970-; Keysar, Boaz (Wiley, 2018)
    Theories of dishonest behavior implicitly assume language independence. Here, we investigated this assumption by comparing lying by people using a foreign language versus their native tongue. Participants rolled a die and ...
  • Deco, Gustavo; Senden, Mario; Jirsa, Viktor K. (Frontiers, 2012)
    Resting state networks (RSNs) show a surprisingly coherent and robust spatiotemporal/norganization. Previous theoretical studies demonstrated that these patterns can be/nunderstood as emergent on the basis of the underlying ...
  • Barbieri, Francesco; Kruszewski, German; Ronzano, Francesco; Saggion, Horacio (ACM Association for Computer Machinery, 2016)
    Choosing the right emoji to visually complement or con- dense the meaning of a message has become part of our daily life. Emojis are pictures, which are naturally combined with plain text, thus creating a new form of ...
