  • Ramírez, Rafael,1966-; Hazan, Amaury; Gómez Gutiérrez, Emilia, 1975-; Maestre Gómez, Esteban; Serra, Xavier (Taylor & Francis (Routledge), 2005)
    If-then rules are one of the most expressive and intuitive knowledge representations and their application to represent musical knowledge raises particularly interesting questions. In this paper, we describe an approach ...
  • Parés, Narcís, 1966-; Masri, Paul; van Wolferen, Gerard; Creed, Chris (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    This paper presents an adaptive physical environment that allows children with severe autism to successfully interact with/nmultimodal stimuli, giving them a sense of control of the interaction and, hence, providing them ...
  • Bonet, Blai; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2005)
    We describe the version of the GPT planner to be used in the planning competition. This version, called mGPT, solves mdps specified in the ppddl/nlanguage by extracting and using different classes of lower bounds, along ...
  • Hernández Leo, Davinia; Asensio-Pérez, Juan I.; Dimitriadis, Yannis (International Forum of Educational Technology & Society, 2005)
    The identification and integration of reusable and customizable CSCL (Computer Supported Collaborative Learning) may benefit from the capture of best practices in collaborative learning structuring. The authors have proposed ...
  • Hernández Leo, Davinia; Asensio-Pérez, Juan I.; Dimitriadis, Yannis; Bote-Lorenzo, Miguel L.; Jorrín-Abellán, Iván M.; Villasclaras-Fernández, Eloy D. (ACTA Press, 2005)
    Designs of CSCL (Computer Supported Collaborative Learning)/nactivities should be flexible, effective and customizable to/nparticular learning situations. On the other hand, structured/ndesigns aim to create favourable ...
  • Tulino, Antonia M.; Lozano Solsona, Angel; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    This paper applies random matrix theory to obtain analytical characterizations of the capacity of correlated multiantenna channels. The analysis is not restricted to the popular separable correlation model, but rather it ...
  • 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 ...
  • Parés, Narcís, 1966-; Carreras, Anna; Durany, Jaume; Ferrer, Jaume; Freixa Font, Pere; Gómez, David; Kruglanski, O.; Parés, Roc, 1968-; Ribas, Joan Ignasi; Soler, M.; Sanjurjo, A. (Mary Ann Liebert, Inc, 2006)
    On starting to think about interaction design for low-functioning persons in the autistic spectrum (PAS), especially children, one finds a number of questions that are difficult to answer: Can we typify the PAS user? Can ...
  • Parés, Narcís, 1966-; Parés, Roc, 1968- (MIT Press, 2006)
    After analyzing how VR experiences are modeled within human computer interaction (CHI) we have found there is a deep theoretical gap. Similarly to how the scientific community has defined CHI models for multimedia applications, ...
  • Lozano Solsona, Angel; Tulino, Antonia M.; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    The analysis of the multiantenna capacity in the high-SNR regime has hitherto focused on the high-SNR slope (or maximum multiplexing gain), which quantifies the multiplicative /nincrease as function of the number of antennas. ...
  • Tulino, Antonia M.; Lozano Solsona, Angel; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    We characterize the capacity-achieving input covariance for multi-antenna channels known instantaneously at the receiver and in distribution at the transmitter. Our characterization, valid for arbitrary numbers of antennas, ...
  • Lozano Solsona, Angel; Tulino, Antonia M.; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    The mutual information of independent parallel Gaussian-noise channels is maximized, under an average power constraint, by independent Gaussian inputs whose power is allocated according to the waterfilling policy. In ...
  • 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 ...
  • Jorrín-Abellán, Iván M.; Ruiz-Requies, Inés; Hernández Leo, Davinia; Villasclaras-Fernández, Eloy D.; Dimitriadis, Yannis; Rubia-Avi, Bartolomé; Asensio-Pérez, Juan I. (International Forum of Educational Technology & Society, 2006)
    This paper introduces Collage, a high-level IMS-LD compliant authoring tool that is specialized for CSCL (Computer-Supported Collaborative Learning). Nowadays CSCL is a key trend in elearning since it highlights the ...
  • Ballester, Coloma; Bertalmío, Marcelo; Caselles, Vicente; Garrido Ostermann, Luis; Marques, Adrián; Ranchin, Florent (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Video is usually acquired in interlaced format, where each image frame is composed of two image fields, each field/nholding same parity lines. However, many display devices require progressive video as input; also, many ...
  • Deco, Gustavo; Scarano, Leandro; Soto-Faraco, Salvador, 1970- (Society for Neuroscience, 2007)
    Recent single-cell studies in monkeys (Romo et al., 2004) show that the activity of neurons in the ventral premotor cortex covaries with the animal's decisions in a perceptual comparison task regarding the frequency of ...
  • Ramírez, Rafael,1966-; Maestre Gómez, Esteban; Pertusa, Antonio; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    We propose a novel approach to the task of identifying performers from their playing styles. We investigate how skilled musicians (Jazz saxophone players in particular) express and communicate their view of the musical and ...
