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 ... -
Influència de dos programes d'entrenament amb relació a les manifestacions de la força a les extremitats inferiors i la qualitat de vida d'un col·lectiu de persones grans
(2013)La societat està envellint de forma progressiva i previsible. Aquest fenomen ens dirigeix cap a noves estructures demogràfiques amb un nombre elevat d’ancians. Les polítiques sociosanitàries de la majoria ... -
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 ... -
A Canonical Genetic Algorithm for Blind Inversion of Linear Channels
(2006)It is well known the relationship between source separation and blind deconvolution: If a filtered version of an unknown i.i.d. signal is observed, temporal independence between samples can be used ... -
A Robust Multiple Feature Approach To Endpoint Detection In Car Environment Based On Advanced Classifiers
(2005)In this paper we propose an endpoint detection system based on the use of several features extracted from each speech frame, followed by a robust classifier (i.e Adaboost and Bagging of decision trees, ... -
Integrative analysis of the Regulatory Region of the FGFR3 Oncogene
(2011)The study of transcriptional regulation often needs the integration of diverse yet independent data. In the present work, sequence conservation, predic-tion of transcription factor binding sites (TFBS) ... -
Maximum likelihood Linear Programming Data Fusion for Speaker Recognition
(2009)Biometric system performance can be improved by means of data fusion. Several kinds of information can be fused in order to obtain a more accurate classification (identification or verification) of ...
