Frequentist and Bayesian approaches for interval-censored data
(2004)Interval censoring appears when the event of interest is only known to have occurred within a random time interval. Estimation and hypothesis testing procedures for interval-censored data are surveyed. ... -
Aproximación al tratamiento paliativo del enfermo con enfermedad oncológica avanzada
(2013)Los pacientes con enfermedad avanzada y/o terminal presentan múltiples síntomas, con un impacto global en la persona que requieren un abordaje integral de los mismos y una intervención multidisciplinar. ... -
Domestic Knowledge, Inequalities and Differences
(2000)This article explores the articulation of domestic knowledge, which is portrayed as a feature of the feminine difference, with class and sexist inequalities. It argues that domestic knowledge can ... -
Análisis de la responsabilidad social corporativa en empresas del mercado continuo español
(2011)En este trabajo se presenta un análisis descriptivo de la responsabilidad social corporativa, en el área medioambiental. En concreto, se estudia la información medioambiental que detallan las empresas ... -
Automatic Trend Line Generation f or timeseries analysis: a Graphical Approach
(2013)Trend lines are revealed useful to explain the past evolution of timeseries of prices that are represented on graphics. However, in practice, there are a huge amount of possible trend lines to be ... -
¿Llegamos a un acuerdo?
(2007)Negociar es un arte pero también una ciencia. El abogado que conozca los elementos y procesos fundamentales envueltos en la negociación estará en las mejores condiciones para gestionarla y llegar a un ... -
Improving Early Diagnosis of Alzheimer's Disease Using Synchrony Measures
(2013)It is well-known that Alzheimer's disease causes changes on the electroencephalography of the patients. However those changes are difficult to parameterize. In this paper a new ratio between synchrony ... -
Blind source separation for solid-state chemical Sensors Arrays
(2004)Electronic noses and tongues are two recent examples in chemical sensing that employ statistical array techniques in order to overcome the intrinsic limitations of current solid-state chemical sensors ... -
Improving algorithm speed in PNL mixture separation and Wiener system inversion
(2003)This paper proposes a very simple method for increasing the algorithm speed for separating sources from PNL mixtures or invertingWiener systems. The method is based on a pertinent initialization of ... -
Algoritmos interactivos para la separación de fuentes y deconvolución de canal mediante Java
(2000)El objetivo de estos programas es crear una herramienta que nos permita, de una manera fácil, entender mejor la separación de fuentes y la deconvolución de canal . Por eso se presenta el diseño, ... -
Climate change impacts on lakes: an integrated ecological perspective based on a multi-faceted approach, with special focus on shallow lakes
(2014)Freshwater ecosystems and their biodiversity are presently seriously threatened by global development and population growth, leading to increases in nutrient inputs and intensification of eutrophicat ... -
A Gradient based algorithm for blind inversion of Wiener System using multi-variate score functions
(2003)A Wiener system is a linear time-invariant filter, followed by an invertible nonlinear distortion. Assuming that the input signal is an independent and identically distributed (iid) sequence, we ... -
Blind Inversion of Wiener System using a minimization-projection (MP) approach
(2003)In this paper, a new algorithm for blind inversion of Wiener systems is presented. The algorithm is based on minimization of mutual information of the output samples. This minimization is done through ... -
Simulated Annealing, High-Order Statistics and Mutual Information for Separation of Sources
(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 ... -
Source separation techniques applied to linear prediction
(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 ... -
Defining ecologically relevant water quality targets for lakes in Europe
(2014)1. The implementation of the Water Framework Directive requires EU member states to establish and harmonize ecological status class boundaries for biological quality elements. In this paper, we describe ... -
La colaboración científica en turismo: grupos y redes de investigación en Cataluña
(2014)El objetivo del presente artículo es analizar la colaboración científica en el campo del turismo en Cataluña: caracterizar a los grupos de investigación; estudiar la colaboración de grupos, instituciones ...
