    According to the Encyclopadia Britannica, the establishment of the Royal Society of London for Improving Natural Knowledge (Royal Society), the "oldest national scientific society in the world," was on November 28, 1660. ...
  • Caro Repetto, Rafael (Universitat Autònoma de Barcelona. Grupo de Investigación Inter Asia. Centro de Estudios e Investigación sobre Asia Oriental, 2012)
    Con el objetivo de evaluar las principales tendencias que afectan a las producciones contemporáneas de ópera de Beijing, el presente artículo estudiará los procesos por los cuales a lo largo del siglo XX y la primera década ...
  • Marín, Victoria I.; Asensio-Pérez, Juan I.; Villagrá-Sobrino, Sara L.; Hernández Leo, Davinia; García-Sastre, Sara (Taylor & Francis, 2018)
    This article describes a study of online collaborative design in the context of teacher professional development. Twenty-five teachers from different Spanish universities participated in the online course. The aim was to ...
  • Öktem, Alp; Farrús, Mireia; Bonafonte, Antonio (International Speech Communication Association (ISCA), 2019)
    Dubbing is a type of audiovisual translation where dialogues are translated and enacted so that they give the impression that the media is in the target language. It requires a careful alignment of dubbed recordings ...
  • Accuosto, Pablo; Saggion, Horacio (ACL (Association for Computational Linguistics), 2019)
    In this work we propose to leverage resources available with discourse-level annotations to facilitate the identification of argumentative components and relations in scientific texts, which has been recognized as a ...
  • Albó, Laia; Barria-Pineda, Jordan; Brusilovsky, Peter; Hernández Leo, Davinia (Springer, 2019)
    Although many efforts are being made to provide educators with dashboards and tools to understand student behaviors within specific technological environments (learning analytics), there is a lack of work in supporting ...
  • Domínguez Bajo, Mónica; Rohrer, Patrick Louis; Soler-Company, Juan (International Speech Communication Association (ISCA), 2019)
    PyToBI is introduced as a user-friendly toolkit for the automatic annotation of intonation contours using the Tones and Breaks Indexes convention, known as ToBI. Index Terms: speech prosody, ToBI, automatic annotation, speech ...
  • Porcaro, Lorenzo; Gómez Gutiérrez, Emilia, 1975- (2019)
    Listening to music radios is an activity that since the 20th century is part of the cultural habits for people all over the world. While in the case of analog radios DJs are in charge of selecting the music to be ...
  • Daza, Vanesa; Herranz, Javier; Morillo, Paz; Ràfols, Carla (Springer, 2007)
    In a threshold broadcast encryption scheme, a sender chooses (ad-hoc) a set of n receivers and a threshold t, and then encrypts a message by using the public keys of all the receivers, in such a way that the original ...
  • Daza, Vanesa; Morillo, Paz; Ràfols, Carla (Elsevier, 2007)
    Identity-Based cryptography has been proposed in mobile ad-hoc networks (MANETs) to provide security. However, the figure of the Private Key Generator (PKG) is not adequate in the MANET setting, since it may not be ...
  • Daza, Vanesa; Herranz, Javier; Morillo, Paz; Ràfols, Carla (Elsevier, 2008)
    In a threshold broadcast encryption scheme, a sender chooses (ad-hoc) a set of n receivers and a threshold t, and then encrypts a message by using the public keys of all the receivers, in such a way that the original plaintext ...
  • Morillo, Paz; Ràfols, Carla (Springer, 2009)
    The relation between list decoding and hard-core predicates has provided a clean and easy methodology to prove the hardness of certain predicates. So far this methodology has only been used to prove that the O(log logN) ...
  • Herranz, Javier; Laguillaumie, Fabien; Ràfols, Carla (Springer, 2010)
    Attribute-based cryptography has emerged in the last years as a promising primitive for digital security. For instance, it provides good solutions to the problem of anonymous access control. In a ciphertext- policy ...
  • Herranz, Javier; Laguillaumie, Fabien; Ràfols, Carla (Elsevier, 2011)
    Semantic security and anonymity are the two main properties that an identity-based encryption scheme can satisfy. Such properties can be de ned in either an adaptive or a selective scenario, which di er on the moment ...
  • Herranz, Javier; Laguillaumie, Fabien; Libert, Benoît; Ràfols, Carla (Springer, 2012)
    Attribute-based cryptography is a natural solution for fine- grained access control with respect to security policies. In the case of attribute-based signatures (ABS), users obtain from an authority their secret keys ...
  • Attrapadung, Nuttapong; Herranz, Javier; Laguillaumie, Fabien; Libert, Benoît; De Panafieu, Elie; Ràfols, Carla (Elsevier, 2012)
    Attribute-based encryption (ABE), as introduced by Sahai and Waters, allows for fine- grained access control on encrypted data. In its key-policy flavor (the dual ciphertext-policy scenario proceeds the other way around), ...
  • Escala, Alex; Herold, Gottfried; Kiltz, Eike; Ràfols, Carla; Villar, Jorge (Springer, 2013)
    We put forward a new algebraic framework to generalize and analyze Di_e-Hellman like Decisional Assumptions which allows us to argue about security and applications by considering only algebraic properties. Our D`;k-MDDH ...
  • Vogl, Richard; Leimeister, Matthias; Nuanáin, Carthach Ó; Hlatky, Michael; Jordà Puig, Sergi; Knees, Peter (Audio Engineering Society, 2016)
    Drum tracks of electronic dance music pieces are a central and style-defining element. Yet,creating them can be a cumbersome task, mostly due to lack of appropriate tools and inputdevices. In this work we use a UI prototype ...
  • Gong, Rong; Serra, Xavier (2017)
    Music Information Retrieval (MIR) technologies have been proven useful in assisting western classical singing training. Jingju (also known as Beijing or Peking opera) singing is different from western singing in terms ...
  • Monte Ordoño, Julia, 1989-; Toro Soto, Juan Manuel, 1976- (Public Library of Science (PLoS), 2017)
    The extraction of abstract structures from speech (or from gestures in the case of sign languages) has been claimed to be a fundamental mechanism for language acquisition. In the present study we registered the neural ...
