Análisis y previsión de fenómenos naturales peligrosos
(Universitat Politècnica de Catalunya. Escola Tècnica Superior d'Enginyers de Camins Canals i Ports de Barcelona, 2011-11-16)
Conference lecture
Open AccessLa toma de decisiones referentes al diseño o en sistemas de alerta requieren el estudio de las acciones externas (frecuentemente meteorológicas), la descripción probabilista del sistema (vulnerabilidad, susceptibilidad) ... -
Bayesian estimation of the orthogonal decomposition of a contingency table
(2015)
Conference report
Open AccessContingency tables can be parametrized by probabilities of each cell in a multinomial sampling. These probabilities constitute the joint probability function of the two or more discrete random categorical variables. These ... -
Bayesian estimation of the orthogonal decomposition of a contingency table
(2016)
Article
Open AccessIn a multinomial sampling, contingency tables can be parametrized by probabilities of each cell. These probabilities constitute the joint probability function of two or more discrete random variables. These probability ... -
Bayesian trend analysis for daily rainfall series of Barcelona
(2010-07-15)
Article
Open AccessA Point-Over-Threshold approach using a reparameterization of the Generalized Pareto Distribution (GPD) has been used to assess changes in the daily rainfall Barcelona series (1854–2006). A Bayesian approach, considering ... -

Article
Open AccessThis research investigates the traffic share evolution of the container throughput in the Mediterranean ports from 2000 to 2015 considering hierarchical clustering and concentration indexes. Compositional Data analysis ... -
Characterizing the evolution of the Yangtze River Delta multi-port system using compositional data techniques
(2021-09-12)
Article
Open AccessThe Yangtze River Delta multi-port system (YMPS) receives increasing attention due to its relevance in world trade and excellent competitiveness in the container traffic market. To insight into the development pattern of ... -
Checking model-data weather hazard occurrence fit in the context of climate change
(2011)
Conference report
Open AccessIn climate change impact studies it is common to run a given response model (from ecosystem changes to wavestorm or landslide occurrence) nested into one of the available long-term Global or Regional Circulation Models ... -
Climate change in a Point-Over-Threshold model: an example on ocean-wave-storm hazard in NE Spain
(2010-09-27)
Article
Open AccessA reparametrization of the Generalized Pareto Distribution is here proposed. It is suitable to parsimoniously check trend assumptions within a Point-Over-Threshold model of hazardous events. This is based on considerations ... -
