  • 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 ...
  • Hernández Leo, Davinia; Agostinho, Shirley; Beardsley, Marc; Bennet, Sue; Lockyer, Lori (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 ...
  • Segovia-Aguas, Javier; Jiménez, Sergio; Jonsson, Anders (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 ...
  • 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 ...
  • 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 ...
  • Michos, Konstantinos; Hernández Leo, Davinia; Jiménez-Morales, Manel (CEUR Workshop Proceedings, 2017)
    A range of data analytics is provided to educators about the profile, behavior and satisfaction of students participating in a Massive Open Online Course (MOOC). However, limited research has been conducted on how ...
  • Barbieri, Francesco; Camacho-Collados, Jose (ACL (Association for Computational Linguistics), 2018)
    In this paper we analyze the use of emojis in social media with respect to gender and skin tone. By gathering a dataset of over twenty two million tweets from United States some findings are clearly highlighted after ...
  • Barbieri, Francesco; Camacho-Collados, Jose (ACL (Association for Computational Linguistics), 2018)
    In this paper we analyze the use of emojis in social media with respect to gender and skin tone. By gathering a dataset of over twenty two million tweets from United States some findings are clearly highlighted after ...
  • Farrús, Mireia; Wagner, Michael; Anguita, Jan; Hernando, Javier (International Speech Communication Association (ISCA), 2008)
    Voice imitation is one of the potential threats to security systems that use automatic speaker recognition. Since prosodic features have been considered for state-of-the-art recognition systems in recent years, the question ...
  • 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 ...
  • Albó Pérez, Laia; Hernández Leo, Davinia (Springer, 2018)
    Despite the existing variety of learning design tools, there is a gap in their understanding and adoption by the educators in their everyday practices. Sharing is one of the main pillars of learning design but sometimes ...
  • Hernández Leo, Davinia; Asensio-Pérez, Juan I.; Derntl, Michael; Prieto, Luis P.; Chacón Pérez, Jonathan, 1986- (Springer, 2014)
