  • Cano, Pedro; Koppenberger, Markus; Wack, Nicolas (ACM Association for Computer Machinery, 2005)
    We present a metadata free system for the interaction with massive collections of music, the MusicSurfer. MusicSurfer automatically extracts descriptions related to instrumentation, rhythm and harmony from music audio ...
  • Herrera Boyer, Perfecto; Bello, Juan; Widmer, Gerhard; Sandler, Mark; Celma Herrada, Òscar; Vignoli, Fabio; Pampalk, Elias; Cano, Pedro; Pauws, Steffen; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    The SIMAC project addresses the study and development of innovative components for a music information retrieval system. The key feature is the usage and exploitation of semantic descriptors of musical content that are ...
  • Eyras Jiménez, Eduardo; Reymond, Alexandre; Castelo Valdueza, Robert; Bye, Jacqueline M.; Cámara, Francisco; Flicek, Paul; Huckle, Elizabeth J.; Parra Farré, Genís; Shteynberg, David D.; Wyss, Carine; Rogers, Jane; Antonarakis, Stylianos E.; Birney, Ewan; Guigó Serra, Roderic; Brent, Michael R. (BioMed Central, 2005)
    Background: Despite the continuous production of genome sequence for a number of organisms,/nreliable, comprehensive, and cost effective gene prediction remains problematic. This is particularly/ntrue for genomes for which ...
  • Samardzija, Dragan; Lozano Solsona, Angel; Papadias, Constantinos B (Hindawi, 2005)
    In single-user MIMO communication, the first-order throughput scaling is determined by the smallest of the number of transmit and receive antennas. This typically renders terminals the constraining bottleneck. In a multiuser ...
  • Hernando, Javier; Farrús, Mireia; Ejarque, Pascual; Garde, Ainara; Luque, Jordi; Comunicació presentada a: SECRYPT 2006, International Conference on Security and Cryptography, celebrada a Setúbal, Portugal, del 7 al 10 d'agost de 2006 (INSTICC Press, 2006)
    Prosodic information can be used successfully for automatic speaker recognition, although most of the speaker recognition systems use only short-term spectral features as voice information. In this work, prosody information ...
  • Gouyon, Fabien; Widmer, Gerhard; Serra, Xavier; Flexer, Arthur (University of California Press, 2006)
    This article brings forward the question of which acoustic features are the most adequate for identifying beats computationally in acoustic music pieces. We consider many different features computed on consecutive short ...
  • Celma Herrada, Òscar; Herrera Boyer, Perfecto; Serra, Xavier (CEUR Workshop Proceedings, 2006)
    In this paper we present the music information plane and the dfferent levels of information extraction that exist in the musical domain. Based on this approach we propose a way to overcome the existing semantic gap in ...
  • Touriño Raposo, Clara; Maldonado, Rafael, 1961-; Valverde Granados, Olga (Springer, 2007)
    3, 4-Methylenedioxymethamphetamine (MDMA) and cannabis are widely abused illicit drugs that are frequently consumed in combination. Interactions between these two drugs have been reported in several pharmacological responses ...
  • Biglieri, Ezio (National Institute of Information and Communications Technology (NICT), 2008)
    We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number of active interferers. Using a statistical-physics approach, we compute the single-user channel ...
  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (European Association for Signal Processing (EURASIP), 2008)
    Silver Code (SilC) was originally discovered in [1–4] for 2×2 multiple-input multiple-output (MIMO) transmission. It has non-vanishing minimum determinant 1/7, slightly lower than Golden code, but is fast-decodable, i.e., ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975-; Herrera Boyer, Perfecto; Serra, Xavier (Taylor & Francis (Routledge), 2008)
    Motivated by evidence that image source statistics predict the response properties of several visual perception aspects, we provide an empirical analysis of the relation between chroma statistics and human judgments of ...
  • Almeida, Rita; Ledberg, Anders (BioMed Central, 2008)
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    In this paper, we introduce a pilot-aided multipath channel estimator for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. Typical estimation algorithms assume the number of ...
  • Biglieri, Ezio; Grossi, Emanuele; Lops, Marco; Tauste Campo, Adrià (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We study the minimum mean square error (MMSE) and the multiuser efficiency η of large dynamic multiple access communication systems in which optimal multiuser detection is performed at the receiver as the number and the ...
  • Rueda Pozo, Silvia; Artazcoz Lazcano, Lucía, 1963-; Navarro, Vicenç, 1937- (BMJ Publishing Group, 2008)
    Background: This paper analyses gender inequalities in health status and in social determinants of health among the elderly in Western Europe. Methods: Data came from the first wave of the “Survey of Health, Ageing and ...
  • Pérez Sanagustín, Maria del Mar; Hernández Leo, Davinia; Santos Rodríguez, Patrícia; Sayago Barrantes, Sergio; Blat, Josep; Griffiths, Dai (International Association of Online Engineering (IAOE), 2008)
    Dialogic learning and interactive groups have proved to be a useful methodological approach applied/nin educational situations for lifelong adult learners. The principles of this approach stress the/nimportance of dialogue ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (European Association for Signal Processing (EURASIP), 2008)
    In multiuser detection, the set of users active at any time may be unknown to the receiver. In these conditions, optimum reception consists of detecting simultaneously the set of active/nusers and their data, problem that ...
  • Purwins, Hendrick; Grachten, Maarten; Herrera Boyer, Perfecto; Hazan, Amaury; Marxer Piñón, Ricard; Serra, Xavier (Elsevier, 2008)
