  • Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    This paper addresses the performance improvement that structured pilot assignment policies can bring about, relative to a random pilot assignment, in cell-free massive MIMO wireless networks. It is shown that structured ...
  • Purohit, Hemant; Castillo, Carlos; Imran, Muhammad; Pandey, Rahul (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    xtensive research on social media usage during emergencies has shown its value to provide life-saving information, if a mechanism is in place to filter and prioritize messages. Existing ranking systems can provide a ...
  • Pasarella Sánchez, Ana Edelmira; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    In this paper we show that the logical framework proposed by Becker et al. [1] to reason about security policy behavior in a trust management context can be captured by an operational framework that is based on the language ...
  • 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 ...
  • Dyer, Chris; Kuncoro, Adhiguna; Ballesteros, Miguel; Smith, Noah A. (ACL (Association for Computational Linguistics), 2016)
    We introduce recurrent neural network grammars,/nprobabilistic models of sentences with/nexplicit phrase structure. We explain efficient/ninference procedures that allow application to/nboth parsing and language modeling. ...
  • Mayor, Oscar; Llimona Torras, Quim; Marchini, Marco, 1984-; Papiotis, Panagiotis, 1985-; Maestre Gómez, Esteban (ACM Association for Computer Machinery, 2013)
    In this technical demo we present repoVizz (http://repovizz.upf.edu), an integrated online system capable of structural formatting and remote storage, browsing, exchange, annotation, and visualization of synchronous ...
  • Mayor, Oscar; Llop, Jordi; Maestre Gómez, Esteban (International Society for Music Information Retrieval (ISMIR), 2011)
    RepoVizz is a data repository and visualization tool for/nstructured storage and user-friendly browsing of music performance/nmulti-modal recordings. The primary purpose of/nRepoVizz is to offer means for the scientific ...
  • Martínez, Kenia; Joshi, Anand A.; Madsen, Sarah K.; Joshi, Shantanu; Karama, Sherif; Román, Francisco J.; Villalon-Reina, Julio; Burgaleta, Miguel; Thompson, Paul M.; Colom, Roberto (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Neuroimaging techniques are now widely used to understand relationships between brain features and cognitive performance. Nevertheless, studies do not always implicate the same anatomical neural networks in intellectual ...
  • Gialampoukidis, Ilias; Moumtzidou, Anastasia; Tsikrika, Theodora; Vrochidis, Stefanos; Kompatsiaris, Ioannis (ACM Association for Computer Machinery, 2016)
    Searching for multimedia objects with heterogeneous modal- ities is critical for the construction of e ective multimedia retrieval systems. Towards this direction, we propose a framework for the multimodal fusion of visual ...
  • Burga Díaz, Alicia; Öktem, Alp; Wanner, Leo (ACL (Association for Computational Linguistics), 2017)
    In this paper, we present a revision of the training set of the METU-Sabancı Turkish syntactic dependency treebank composed of 4997 sentences in accordance with the principles of the Meaning-Text Theory (MTT). MTT reflects ...
  • Gómez Marín, Daniel; Jordà Puig, Sergi; Herrera Boyer, Perfecto (International Workshop on Musical Metacreation, 2016)
    We present and discuss our view on rhythm spaces, as metaphors to visualize and interact with rhythms. We take advantage on existing research on alternative lowdimensional music spaces, music cognition, music interaction ...
  • Farrús, Mireia; Wagner, Michael; Anguita, Jan; Hernando, Javier (International Speech Communication Association (ISCA), 2008)
    Prosody plays an important role in the human recognition process; therefore, prosodic elements are normally used by impersonators aiming to resemble someone else. Since such voice imitation is one of the potential threats ...
  • Arcos, Josep Lluís; López de Mántaras, Ramon; Serra, Xavier (International Computer Music Conference, 1997)
    We have studied the problem of generating expressive musical performances in the context of tenor saxophone interpretations. We have done several recordings of a tenor sax playing dierent Jazz ballads with dierent degrees ...
  • Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2013)
    Tonic is a fundamental concept in many music traditions/nand its automatic identification should be relevant for establishing/nthe reference pitch when we analyse the melodic/ncontent of the music. In this paper, we present ...
  • Pons Puig, Jordi; Gong, Rong; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    This paper introduces a new score-informed method for the segmentation of jingju a cappella singing phrase into syllables. The proposed method estimates the most likely sequence of syllable boundaries given the estimated ...
  • Gong, Rong; Obin, Nicolas; Dzhambazov, Georgi Bogomilov; Serra, Xavier (Folk Music Analysis, 2017)
    This paper introduces a new unsupervised and score-informed method for the segmentation of singing voice into syllables. The main idea of the proposed method is to detect the syllable onset on a probability density ...
  • Dzhambazov, Georgi Bogomilov; Sentürk, Sertan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2015)
    Search by lyrics, the problem of locating the exact occurrences of a phrase from lyrics in musical audio, is a recently emerging research topic. Unlike key-phrases in speech, lyrical key-phrases have durations that bear ...
  • Anguera Miró, Xavier, 1978-; Farrús, Mireia; Hernando, Javier (2004)
    L'evolució de la societat de la informació ha esdevingut un incessant increment de continguts audiovisuals que s’emeten constantment en cadenes de televisió i emissores de radio locals i nacionals en llengua catalana. ...
