  • Ezeoke, Maurice; Borda Fortuny, Cristina; Tong, Kenneth (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A barefaced terrain scattering model for oil sand exploration will enable the discrimination of different terrain types using incoherent polarimetric decomposition. We use computer electromagnetic modeling with finite ...
  • Amiri, A.; Borda Fortuny, Cristina; Tong, Kin-Fai (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Two different reconfigurable techniques for spectrum-monitoring antenna are presented. The first method inserts high-performance RF-MEMS switches along the microstrip feed line and back slot of a Vivaldi antenna ...
  • 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 ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Wong, Kai-Kit (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    This article proposes a novel liquid switch to reconfigure the operating frequency of a frequency-independent antenna. A Vivaldi antenna using a low-cost GaAs MMIC RF switch is used as a landmark to compare the measured ...
  • 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 ...
  • Saggion, Horacio; Ferrés, Daniel; Sevens, Leen; Schuurman, Ineke; Ripollés, Marta; Rodríguez, Olga (ACM Association for Computer Machinery, 2017)
    The Able to Include project aims at improving the living conditions of people with intellectual or developmental disabilities (IDD) in key areas of society. One of its focus points concerns improving the integration of ...
  • Espinosa-Anke, Luis; Saggion, Horacio (Springer, 2014)
    Definition Extraction (DE) is the task to automatically identify definitional knowledge in naturally-occurring text. This task has applications in ontology generation, glossary creation or question answering. Although the ...
  • Barbieri, Francesco; Marujo, Luís; Karuturi, Pradeep; Brendel, William; Saggion, Horacio (CEUR Workshop Proceedings, 2018)
    The frequent use of Emojis on social media platforms has created a new form of multimodal social interaction. Developing methods for the study and representation of emoji semantics helps to improve future multimodal ...
  • Espinosa-Anke, Luis; Oramas, Sergio; Camacho-Collados, Jose; Saggion, Horacio (2016)
    Lexical taxonomies are tree or directed acyclic graph-like structures where each node represents a concept and each edge encodes a binary hypernymic (is-a) relation. These lexical resources are useful for AI tasks like ...
  • Espinosa-Anke, Luis; Ronzano, Francesco; Saggion, Horacio (Springer, 2015)
    Hypernym extraction is a crucial task for semantically motivated NLP tasks such as taxonomy and ontology learning, textual entailment or paraphrase identification. In this paper, we describe an approach to hypernym extraction ...
  • Rodríguez, Sonia; Gómez Gutiérrez, Emilia, 1975-; Cuesta i Mussarra, Helena (Folk Music Analysis, 2018)
    This work deals with the automatic transcription and characterization of flamenco guitar, with a focus on short melodic interludes improvised between sung verses. These are called falsetas in the flamenco argot and are ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2012)
    It has been shown recently that the complexity of belief tracking in deterministic conformant and contingent planning is exponential in a width parameter that is often bounded and small. In this work, we introduce a new ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2012)
    In the presence of non-admissible heuristics, A* and other best-first algorithms can be converted into anytime optimal algorithms over OR graphs, by simply continuing the search after the first solution is found. The ...
  • Gómez Gutiérrez, Emilia, 1975-; Guerrero, Alba; Rodríguez, Sonia (2018)
    Cante Flamenco Tech es un proyecto pedagógico cuyo objetivo es el de generar materiales docentes online para el aprendizaje del cante flamenco, siguiendo un énfasis tecnolégico. Para ello, el proyecto integra las tecnologías ...
  • Cuesta i Mussarra, Helena; Gómez Gutiérrez, Emilia, 1975-; Martorell Domínguez, Agustín; Loáiciga, Felipe (2018)
    Choir singers synchronize their fundamental frequency (f0) and timing when they perform together. In this work, we investigate several expressive characteristics of choir singing, with special emphasis on unison ...
  • Slizovskaia, Olga; Gómez Gutiérrez, Emilia, 1975-; Haro Ortega, Gloria (ACM Association for Computer Machinery, 2017)
    This paper presents a method for recognizing musical instruments in user-generated videos. Musical instrument recognition from music signals is a well-known task in the music information retrieval (MIR) field, where current ...
  • Blaauw, Merlijn; Bonada, Jordi, 1973- (International Speech Communication Association (ISCA), 2017)
    We present a new model for singing synthesis based on a modified version of the WaveNet architecture. Instead of modeling raw waveform, we model features produced by a parametric vocoder that separates the influence of ...
  • Baumgartner, Laura; González Ballester, Miguel Ángel, 1973-; Noailly, Jérôme (International Research Council on Biomechanics of Injury (IRCOBI), 2018)
    The causes of intervertebral disc (IVD) ruptures continue to elude both biomechanists and clinicians. It is widely accepted that unique traumatic high‐load impacts are unlikely to lead to isolated IVD herniation. Therefore, ...
  • Schmitt, Kai‐Uwe; Baumgartner, Laura; Muser, Markus; Furter, Kerstin; Scholz, Stefan; Lüber, Barbara; Thomas, Pete; Simma, Anja (International Research Council on Biomechanics of Injury (IRCOBI), 2014)
    National accident statistics in European countries as well as in many other countries are based on data recorded by the police. Generally, such data also include police reported estimates of the injury severity of accident ...
  • Barbieri, Francesco; Espinosa-Anke, Luis; Camacho-Collados, Jose; Schockaert, Steven; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    Human language has evolved towards newer forms of communication such as social media, where emojis (i.e., ideograms bearing a visual meaning) play a key role. While there is an increasing body of work aimed at ...
