Recent Submissions

  • Crowell, Ciera; Mora Guiard, Joan; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2018)
    When players enter into an interactive game setting, they undertake a process of discovery and subsequent distinguishing of the rules and goals which will prevail in the play context. However, this process of forming ...
  • Crowell, Ciera; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2018)
    Interpersonal distance is defined as the area which we choose to keep between ourselves and others, revealed through observation and cultural components. Although previous studies have suggested the possibility of alterations ...
  • 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- (CEUR Workshop Proceedings, 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 ...
  • 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; 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 ...
  • 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 ...
  • 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 ...
  • Herold, Gottfried; Hesse, Julia; Hofheinz, Dennis; Ràfols, Carla; Rupp, Andy (Springer, 2014)
    At Eurocrypt 2010, Freeman presented a framework to convert cryptosystems based on composite-order groups into ones that use prime-order groups. Such a transformation is interesting not only from a conceptual point of ...
  • Escala, Alex; Herranz, Javier; Libert, Benoît; Ràfols, Carla (Springer, 2014)
    Lossy trapdoor functions, introduced by Peikert and Waters (STOC’08), have received a lot of attention in the last years, because of their wide range of applications. The notion has been recently extended to the ...
  • Ràfols, Carla (Springer, 2015)
    Groth, Ostrovsky and Sahai constructed a non-interactive Zap for NP-languages by observing that the common reference string of their proof system for circuit satisfiability admits what they call correlated key generation. ...
  • González, Alonso; Hevia, Alejandro; Ràfols, Carla (Springer, 2015)
    A sequence of recent works have constructed constant-size quasi-adaptive (QA) NIZK arguments of membership in linear subspaces of ^Gm, where ^G is a group equipped with a bilinear map e : G x H --> T. Although applicable ...
  • Morillo, Paz; Ràfols, Carla; Villar, Jorge L. (Springer, 2016)
    We put forward a new family of computational assumptions, the Kernel Matrix Diffi-Hellman Assumption. Given some matrix A sampled from some distribution D, the kernel assumption says that it is hard to find \in the ...
  • Ramires, António; Serra, Xavier (2019)
    Reusing recorded sounds (sampling) is a key component in Electronic Music Production (EMP), which has been present since its early days and is at the core of genres like hip-hop or jungle. Commercial and non-commercial ...
  • Nuñez-Garcia, Marta; Bernardino Perez, Gabriel; Doste, Rubén; Zhao, Jichao; Camara, Oscar; Butakoff, Constantine (Springer, 2019)
    Two-dimensional standard representations of 3D anatomical structures are a simple and intuitive way for analysing patient information across populations and image modalities. They also allow convenient visualizations that ...
