Anna Senyé : Notes biogràfiques i recorregut poètic
(2011)Anna Senyé Ramisa (Manlleu, 1881-Barcelona, 1956) fou una dona de caràcter aventurer que va tenir una vida poc convencional. Va escriure en diferents revistes i diaris catalans des de 1914 i durant ... -
Quasi-Nonparametric Blind Inversion of Wiener Systems
(2001)An e cient procedure for the blind inversion of a nonlinear Wiener system is proposed. We proved that the problem can be expressed as a problem of blind source separation in nonlinear mixtures, for ... -
Non-Linear and Non-Conventional Speech Processing: Alternative Techniques
(2010)This special issue aims to cover some problems related to non-linear and nonconventional speech processing. The origin of this volume is in the ISCA Tutorial and Research Workshop on Non-Linear Speech ... -
A non-linear VAD for noisy environments
(2010)This paper deals with non-linear transformations for improving the performance of an entropy-based voice activity detector (VAD). The idea to use a non-linear transformation has already been applied ... -
Investigation of ICA algorithms for feature extraction of EEG signals in discrimination of Alzheimer disease
(2008)In this paper we present a quantitative comparisons of different independent component analysis (ICA) algorithms in order to investigate their potential use in preprocessing (such as noise reduction ... -
Coherency and sharpness measures by using ICA algorithms. An investigation for Alzheimer’s disease discrimination
(2009)In this paper, we present a comprehensive study of different Independent Component Analysis (ICA) algorithms for the calculation of coherency and sharpness of electroencephalogram (EEG) signals, in ... -
Contribució a l'estudi de la presència de Balmes en l'obra de Verdaguer
(2011)A partir d’una recerca exhaustiva dins l’obra de Verdaguer, l’article ressegueix la presència de Balmes en la producció de l’escriptor de Folgueroles. Tot i no ésser irrellevant, es constata que el ... -
¿ Sólo informar o también persuadir? Museos y publicidad en España
(2011)Este artículo explora la actual relación de la publicidad convencional con los museos de arte españoles, presentando los dos modelos existentes: el que sólo se preocupa por informar y otro que explora ... -
Norbert Elias : una proposta d’intellectual portrait vint anys després de la seva mort
(2011)L’estiu de 1990 moria a Amsterdam un dels sociòlegs més preeminents del segle XX, l’alemany Norbert Elias. La seva vida i la seva obra, profundament imbricades, són un reflex de la complexitat, de les ... -
Open source software in translator training
(2011)La formació de traductors implica l´ús de procediments i eines que permetin els estudiants familiaritzar-se amb contextos professionals. El software lliure especialitzat inclou eines de qualitat ... -
Tema y narración en Eyes Wide Shut
(2011)A partir de la complejidad argumental y temática de la película Eyes Wide Shut, dirigida por Stanley Kubrick, se presenta una propuesta interpretativa que analiza la relación entre el tema de la ... -
Les nou preguntes que Norbert Elias es va formular : debats, interrogants i pistes per a la sociologia del segle XXI
(2011)En aquest article dedicat a Norbert Elias en commemoració dels vint anys de la seva mort, proposem revisar, de manera resumida, la seva obra a partir dels interrogants ontològics, epistemològics i ... -
Automatic Recognition of Leaves by Shape Detection Pre-Processing with Ica
(2009)In this work we present a simulation of a recognition process with perimeter characterization of a simple plant leaves as a unique discriminating parameter. Data coding allowing for independence of ... -
Improving a leaves automatic recognition process using PCA
(2009)In this work we present a simulation of a recognition process with perimeter characterization of a simple plant leaves as a unique discriminating parameter. Data coding allowing for independence of ... -
Blind channel deconvolution of real world signals using source separation techniques
(2005)In this paper we present a method for blind deconvolution of linear channels based on source separation techniques, for real word signals. This technique applied to blind deconvolution problems is ... -
Parametric Approach to Blind Deconvolution of Nonlinear Channels
(2002)A parametric procedure for the blind inversion of nonlinear channels is proposed, based on a recent method of blind source separation in nonlinear mixtures. Experiments show that the proposed algorithms ... -
Initialisation of Nonlinearities for PNL and Wiener systems Inversion
(2003)This paper proposes a very fast method for blindly initial- izing a nonlinear mapping which transforms a sum of random variables. The method provides a surprisingly good approximation even when ... -
Fast Approximation of Nonlinearities for improving inversion algorithms of PNL mixtures and Wiener systems
(2005)This paper proposes a very fast method for blindly approximating a nonlinear mapping which transforms a sum of random variables. The estimation is surprisingly good even when the basic assumption is ... -
Post-Nonlinear Mixtures and Beyond
(2004)Although sources in general nonlinear mixturm arc not separable iising only statistical independence, a special and realistic case of nonlinear mixtnres, the post nonlinear (PNL) mixture is separable ... -
Application of the Mutual Information Minimization to speaker recognition / identification improvement
(2006)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 ...
