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 ... -
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 ... -
Multiway Array Decomposition Analysis of EEGs in Alzheimer’s Disease
(2012)Methods for the extraction of features from physiological datasets are growing needs as clinical investigations of Alzheimer’s disease (AD) in large and heterogeneous population increase. General tools ... -
Physical activity promotion in general practices of Barcelona: a case study
(2006)This case study aimed to generate explanations for the lack of integration of physical activity (PA) promotion in general practices of Barcelona, the capital of Catalonia. This explanatory study adopted ... -
Attitudes and practices of physicians and nurses regarding physical activity promotion in the Catalan primary health-care system
(2005)Background: In Catalonia a high percentage of the population remains inactive. General practices are an ideal setting to advise on physical activity (PA). However, there is a lack of evidence regarding ... -
Change in work day step counts, wellbeing and job performance in Catalan university employees: a randomised controlled trial
(2008)Abstract: Using a randomised controlled trial design, this feasibility study assessed the impact of two walking interventions on quality of life (QoL) and job performance of Catalan university employees. A ... -
Promoting stair climbing in Barcelona: similarities and differences with interventions in English-speaking populations
(2010)This study evaluated the ability of three different messages to encourage stair climbing on the Barcelona underground. Two weeks of baseline were followed by three banner intervention periods with ... -
Referral from primary care to a physical activity programme: establishing long-term adherence? A randomized controlled trial. Rationale and study design
(2009)Background: Declining physical activity is associated with a rising burden of global disease. There is little evidence about effective ways to increase adherence to physical activity. Therefore, interventions ...
