  • Score Function for Voice Activity Detection
    Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon; Zaiats, Vladimir (Springer, 2010)
    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 ...
  • Selenoproteins and bladder cancer risk: A case-control study
    Amaral, A.F.S.; Rothman, Nathaniel; Kogevinas, Manolis; Calle, M. Luz; Guey, Lin T.; García-Closas, Montserrat; Silverman, Debra T.; Chanock, Stephen; Real, Francisco X.; Malats i Riera, Núria (Elsevier, 2010)
  • Simulated Annealing, High-Order Statistics and Mutual Information for Separation of Sources
    Solé-Casals, Jordi; Puntonet, Carlos G.; Rojas, I. (2001)
    In this article, the fusion of a stochastic metaheuristic as Simulated Annealing (SA) with classical criteria for convergence of Blind Separation of Sources (BSS), is shown. Although the topic of BSS, by means of various ...
  • Source separation techniques applied to linear prediction
    Solé-Casals, Jordi; Jutten, Christian; Taleb, Anisse (2000)
    The prediction filters are well known models for signal estimation, in communications, control and many others areas. The classical method for deriving linear prediction coding (LPC) filters is often based on the minimization ...
  • Speaker recognition improvement using blind inversion of distortions
    Faundez-Zanuy, Marcos; Solé-Casals, Jordi (2004)
    In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into ...
  • Speech Enhancement: A Multivariate Empirical Mode Decomposition Approach
    Solé-Casals, Jordi; Gallego Jutglà, Esteve; Martí i Puig, Pere; Travieso, Carlos M.; Alonso, Jesús B. (Springer, 2013)
    Speech signals in real scenario ambient are usually mixed with some other signals, such as noise. This may interfere with posterior signal processing applied to the signals. In this work, a new technique of data denoising ...
  • Towards a low-complex breathing monitoring system based on acoustic signals
    Martí i Puig, Pere; Solé-Casals, Jordi; Masferrer Caralt, Gerard; Gallego Jutglà, Esteve (Springer, 2013)
    Monitoring the breathing is required in many applications of medical and health fields, but it can be used also in new game applications, for example. In this work, an automatic system for monitoring the breathing is ...
  • Two Families of Radix-2 FFT Algorithms With Ordered Input and Output Data
    Martí i Puig, Pere (IEEE, 2009)
    Two radix-2 families of fast Fourier transform (FFT) algorithms that have the property that both inputs and outputs are addressed in natural order are derived in this letter. The algorithms obtained have the same ...
  • Video observations of crescentic sandbar formation and modelling implications
    Coco, G.; Ruessink, B.G.; Van Enckevort, I.M.J.; Caballeria, Miquel; Falqués, Albert; Holman, R.A.; Plant, N.G.; Turner, I.L. (World Scientific, 2005)
    The development of surf zonc crescentic sandbars has beeo analyzed using video observations al lhrce sites: Duck (USA), Gold Coast (Australia). and NoordwiJk (The Netherlands). Video observations indicate the developmenl ...
  • Web didáctica para la aproximación de funciones mediante redes neuronales
    Comabella López, Julio; Solé-Casals, Jordi; Hosseini, Sharam; Jutten, Christian (2002)
    In this article we presents a project [1] developed to demonstrate the capability that Multi-Layer Perceptrons (MLP) have to approximate non-linear functions [2]. The simulation has been implemented in Java to be used ...
  • What determines the wavelength of self-organized shoreline sand waves?
    Falqués, Albert; Van den Berg, Niels; Ribas Prats, Francesca; Caballeria, Miquel (2012)
    Shoreline undulations extending into the bathymetric contours with a length scale larger than that of the rhythmic surf zone bars are referred to as shoreline sand waves. Many observed undulations along sandy coasts display ...
