  • Deco, Gustavo; Tagliazucchi, Enzo; Laufs, Helmut; Sanjuán, Ana; Kringelbach, Morten L. (Society for Neuroscience, 2017)
    A precise definition of a brain state has proven elusive. Here, we introduce the novel local-global concept of intrinsic ignition characterizing the dynamical complexity of different brain states. Naturally occurring ...
  • Oramas Martin, Sergio; Gómez, Francisco; Gómez Gutiérrez, Emilia, 1975-; Mora, Joaquín (International Society for Music Information Retrieval (ISMIR), 2015)
    Online information about flamenco music is scattered over different sites and knowledge bases. Unfortunately, there is no common repository that indexes all these data. In this work, information related to flamenco ...
  • González-Suárez, Ana; Herranz, David; Berjano, Enrique J.; Rubio-Guivernau, Jose L.; Margallo-Balbás, Eduardo (Wiley, 2017)
    Background/Objective: Radiofrequency (RF) catheter ablation is a minimally invasive medical procedure used to thermally destroy the focus of cardiac arrhythmias. Novel optical techniques are now being integrated into RF ...
  • Pérez, Juan J.; González-Suárez, Ana; Berjano, Enrique J. (Taylor & Francis (Routledge), 2017)
    Purpose: The thermal effect of the intramyocardial blood perfusion on the size of lesions created by radiofrequency cardiac ablation (RFCA) has not been adequately studied to date. Our objective was to assess the impact ...
  • Oramas, Sergio; Espinosa-Anke, Luis; Sordo, Mohamed; Saggion, Horacio; Serra, Xavier (Elsevier, 2016)
    The rate at which information about music is being created and shared on the web is growing exponentially. However, the challenge of making sense of all this data remains an open problem. In this paper, we present and ...
  • George, Geordie; Mungara, Ratheesh K.; Lozano Solsona, Angel; Haenggi, Martin (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This paper shows how the application of stochastic geometry to the analysis of wireless networks is greatly facilitated by: (i) a clear separation of time scales; (ii) the abstraction of small-scale effects via ergodicity; ...
  • Senanayake, Rajitha; Lozano Solsona, Angel; Smith, Peter; Evans, Jamie (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper considers distributed massive MIMO networks where a large number of antennas, either collocated or geographically scattered over a region, communicate with mobile users. This communication is impaired by ...
  • George, Geordie; Mungara, Ratheesh K.; Lozano Solsona, Angel; Haenggi, Martin (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    The application of stochastic geometry to the analysis of wireless networks is shown to be propelled by (i) a clean separation of time scales, (ii) abstraction of small-scale effects via ergodicity, and (iii) an interference ...
  • Mungara, Ratheesh K.; Thibault, Ilaria; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This paper characterizes, through a stochastic geometry analysis, the increase in spectral efficiency that full-duplex transmission brings about in wireless networks. While, on isolated links, full-duplex promises a doubling ...
  • George, Geordie; Venugopal, Kiran; Lozano Solsona, Angel; Heath, R. W., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This paper investigates the feasibility of mmWave frequencies for personal networks of wireless wearable devices in enclosed settings (e.g., commuter trains, subways, airplanes, airports, or offices). At these frequencies, ...
  • Paun, Bruno; Bijnens, Bart; Butakoff, Constantine (Wiley, 2017)
    Contemporary imaging modalities offer non-invasive quantification of myocardial deformation; however, they make gross assumptions about internal structure of the cardiac walls. Our aim is to study the possible impact of ...
  • Cerdà, Ramon; Farrús, Mireia; Hernando, Javier; Veyrat Rigat, Montserrat (Dirección Xeral de Creación e Difusión Cultural, 2007)
    La presente comunicación no ofrece todavía resultados de ningún experimento ya ejecutado, sino, com su título indica, una serie de comentarios en torno a la noción de "campo de dispersión fonemática" (o "fonológica") o ...
  • Farrús, Mireia; Anguita, Jan; Hernando, Javier; Cerdà, Ramon (Dirección Xeral de Creación e Difusión Cultural, 2007)
    Los sistemas automáticos de reconocimiento de locutor más utilizados recientemente están basados en características acústicas de bajo nivel, como las magnitudes espectrales, las frecuencias de los formantes, etc. Sin ...
  • Farrús, Mireia; Erro, Daniel; Hernando, Javier (Universidad de Valladolid, 2008)
    Security systems relying on voice identification can be threatened by human voice imitation or synthetic voices. As voice conversion can be seen as a sort of voice imitation, this paper analyses the performance of an ...
  • Manathunga, Kalpani; Hernández Leo, Davinia (Wiley, 2017)
    Collaborative Learning Flow Patterns (CLFPs) formulate best practices for the orchestration of activity sequences and collaboration mechanisms that can elicit fruitful social interactions. Mobile technology features offer ...
  • Leiva, Víctor; Freire, Ana (Springer, 2017)
    The statistics presented by the World Health Organization inform that 90% of the suicides can be attributed to mental illnesses in high-income countries. Besides, previous studies concluded that people with mental illnesses ...
  • Morenza-Cinos, Marc; Casamayor-Pujol, Victor; Soler Busquets, Jordi; Sanz, José Luis; Guzmán, Roberto; Pous Andrés, Rafael (Springer, 2017)
    AdvanRobot proposes a new robot for inventorying and locating all the products inside a retail store without the need of installing any fixed infrastructure. The patent pending robot combines a laser-guided autonomous ...
  • Bengoetxea, Kepa; Atutxa, Aitziber; Iruskieta, Mikel (Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2017)
    En este artículo presentamos el primer detector de la Unidad Central (UC) de resúmenes cient´ıficos en euskera basado en técnicas de aprendizaje automático. Después de segmentar el texto en unidades de discurso elementales, ...
  • Bel Rafecas, Núria; Diz Pico, Jorge; Marimon, Montserrat; Pocostales Mercè, Joel (Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2017)
    We present the system for the classification of sentences and short texts into Marketing Mix classes developed within the LPS-BIGGER project. The system classifies short texts from Social Media into categories that are ...
  • Barbieri, Francesco; Espinosa-Anke, Luis; Ballesteros, Miguel; Soler Company, Juan; Saggion, Horacio (ACL (Association for Computational Linguistics), 2017)
    Videogame streaming platforms have become a paramount example of noisy usergenerated text. These are websites where gaming is broadcasted, and allows interaction with viewers via integrated chatrooms. Probably the ...
