  • Complete Monotonic Semantic Path Orderings
    Borralleras Andreu, Cristina; Ferreira, Maria; Rubio, Albert (Springer, 2000)
    Although theoretically it is very powerful, the semantic path ordering (SPO) is not so udeful in practice, since its monotonicity has to be proved by hand for each concrete term rewrite system (TRS). In this paper we present ...
  • Monotonic AC-Compatible Semantic Path Orderings
    Borralleras Andreu, Cristina; Rubio, Albert (Springer, 2003)
    Abstract. Polynomial interpretations and RPO-like orderings allow one to prove termination of Associative and Commutative (AC-)rewriting by only checkingthe rules of the given rewrite system. However, these methods have ...
  • Low-cost printed antennas design in the band of 2,4GHz
    Martí i Puig, Pere; Serra i Serra, Moisès; Carrabina, Jordi (SPIE, 2005)
    In this article we present a study and the corresponding implementation of low cost printed antennas in the 2,4GHz band. These antennas work with low cost transceivers that give a FR input/output signal in the band of ...
  • Improving Pitch Tracking Performance in Hard Noise Conditions by a Preprocessing Based on Mathematical Morphology
    Martí i Puig, Pere; Solé-Casals, Jordi; Reig Bolaño, Ramon (2009)
    In this paper we show how a nonlinear preprocessing of speech signal -with high noise- based on morphological filters improves the performance of robust algorithms for pitch tracking (RAPT). This result happens for a ...
  • Exploring Non-linear Transformations for an Entropybased Voice Activity Detector
    Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon (2009)
    In this paper we explore the use of non-linear transformations in order to improve the performance of an entropy based voice activity detector (VAD). The idea of using a non-linear transformation comes from some previous ...
  • Data compression of natural signals based on Discrete Wavelet transform analysis

  • On cumulant techniques in speech processing
    Zaiats, Vladimir; Solé-Casals, Jordi (2009)
    This paper analyzes applications of cumulant analysis in speech processing. A special focus is made on different second-order statistics. A dominant role is played by an integral representation for cumulants by means ...
  • Otoliths identifiers using image contours EFD
    Reig Bolaño, Ramon; Martí i Puig, Pere; Rodríguez, Sara; Bajo, Javier; Parisi Baradad, Vicenç (Springer Berlín / Heidelberg, 2010)
    Abstract. In this paper we analyze the characteristics of an experimental otolith identification system based on image contours described with Elliptical Fourier Descriptors (EFD). Otoliths are found in the inner ear of ...
  • Campus Móvil: Designing a Mobile Web 2.0 Startup for Higher Education Uses
    Pardo, Hugo; Brandt, Joel (Springer, 2010)
    In the intersection between the mobile Internet, social software and educational environments, Campus Móvil is a prototype of an online application for mobile devices created for a Spanish university community, ...

  • Guia multilingüe d'alimentació saludable
    Torres Moreno, Míriam; Vaqué Crusellas, Cristina; Vila Martí, Anna (2011)
    És una guia que té per objectiu facilitar la comprensió i comunicació en temes alimentaris en un entorn multicultural així com promocionar l'alimentació saludable.
  • m-Todos, tendencias y oportunidades de la movilidad digital
    Contreras, Ruth S. (Ruth Sofhía); García Medina, Irene (Universitat de Vic, 12-2011)
    La difusión de la tercera generación de dispositivos móviles y su integración con la World Wide Web son un reto para los medios de comunicación. Como en cualquier otro ecosistema, la llegada de una "nueva especie" crea ...
  • Convergència mediàtica digital: el consum de continguts i l'ús de nous mitjans per dones a Catalunya

  • Improving Early Diagnosis of Alzheimer's Disease Using Synchrony Measures
    Gallego Jutglà, Esteve; Solé-Casals, Jordi (IOS Press, 2013)
    It is well-known that Alzheimer's disease causes changes on the electroencephalography of the patients. However those changes are difficult to parameterize. In this paper a new ratio between synchrony in 0 and a band ...
