Nonlinear prediction based on score function
(2002)The linear prediction coding of speech is based in the assumption that the generation model is autoregresive. In this paper we propose a structure to cope with the nonlinear effects presents in the ... -
Interval censoring: model characterizations for the validity of the simplified likelihood
(2004)En analyse de durées de vie, le problème de la censure par intervalle a généralement été traité par des méthodes vraisemblantistes. Comme la vraisemblance est complexe, on suppose souvent que les ... -
Distribución espacial de la población inmigrante en los municipios catalanes: igualdad, exposición, concentración y centralidad
(2006)Dado el importante crecimiento de la población inmigrante en España, es interesante estudiar su distribución sobre el territorio urbano. Desde la estadística se dispone de diferentes indicadores con ... -
Tutorial on methods for interval-censored data and their implementation in R
(2009)Interval censoring is encountered in many practical situations when the event of interest cannot be observed and it is only known to have occurred within a time window. The theory for the analysis of ... -
A copula-based method for synthetic microarray data generation
(2012)In this work, we propose a copula-based method to generate synthetic gene expression data that account for marginal and joint probability distributions features captured from real data. Our method ... -
ICA Cleaning procedure for EEG signals analysis: application to Alzheimer's disease detection
(2010)To develop systems in order to detect Alzheimer’s disease we want to use EEG signals. Available database is raw, so the first step must be to clean signals properly. We propose a new way of ICA cleaning ... -
Improving the Quality of EEG Data in Patients With Alzheimers Disease Using ICA
(2008)Does Independent Component Analysis (ICA) denature EEG signals? We applied ICA to two groups of subjects (mild Alzheimer patients and control subjects). The aim of this study was to examine whether ... -
Reducción del vector de características de reconocimiento facial
(2008)In this present work, we are proposing a characteristics reduction system for a facial biometric identification system, using transformed domains such as discrete cosine transformed (DCT) and discrete ... -
Improved Sparse Bump Modeling for Electrophysiological Data
(2008)Bump modeling is a method used to extract oscillatory bursts in electrophysiological signals, who are most likely to be representative of local synchronies. In this paper we present an improved sparse ... -
Beyond the Votes: A European Perspective on the Use of Public Relations to Legitimize Authority in Obama’s Campaign
(2011)In political campaigns in Western society, there are many examples of public relations being behind opinion leaders in getting grassroots committed to a candidate; Obama’s campaign was one example. ... -
Observatorio Barça 2010. La Campaña a la Presodencia del FC Barcelona en prensa deportiva y las redes sociales
(2011)El artículo tiene como objetivo analizar la cobertura que los principales periódicos deportivos catalanes (Sport, Mundo Deportivo, El 9 Esportiu y Gol) hicieron de la campaña a la presidencia del ... -
An Evolutionary Approach for Blind Inversion of Wiener Systems
(2007)The problem of blind inversion of Wiener systems can be considered as a special case of blind separation of post-nonlinear instantaneous mixtures. In this paper, we present an approach for nonlinear ... -
Estimación de funciones no lineales en mezclas post-no lineales
(2007)This paper proposes a new method for blindly inverting a nonlinear mapping which transforms a sum of random variables. This is the case of post-nonlinear (PNL) source separation mixtures. The importance ... -
Prevalence and characteristics of patients with advanced chronic conditions in need of palliative care in the general population: A cross-sectional study
(2014)Background: Of deaths in high-income countries, 75% are caused by progressive advanced chronic conditions. Palliative care needs to be extended from terminal cancer to these patients. However, direct ... -
Cost-benefit and cost-effectiveness of the incorporation of the pneumococcal 7-valent conjugated vaccine in the routine vaccination schedule of Catalonia (Spain)
(2005)The health and economic costs and benefits of vaccinating a cohort of 60,000 children born in Catalonia in the year 2000 with the pneumococcal 7-valent conjugated vaccine were compared with the alternative ... -
Efficiency of the incorporation of the hepatitis A vaccine as a combined A+B vaccine to the hepatitis B vaccination programme of preadolescents in schools
(2005)In 1998, the Department of Health of Catalonia (Spain) began universal vaccination of preadolescents against hepatitisAby replacing the simple hepatitisBvaccine with a combined hepatitisA+Bvaccine. ... -
‘Having words for everything’. Institutionalizing gender migration in Spain (1998–2008)
(2011)Working from an interdisciplinary perspective, this article examines the development of gender identity categories and the institutionalization of sex-reassignment procedures based on two different ... -
An integrated framework combining a traffic simulator and a driving simulator
(2011)Driving simulation has been used for many years now in research, industry and training to simulate virtual driving conditions. This is largely because simulation saves engineering time and costs, and ...
