A spatio-temporal Poisson hurdle point process to model wildfires
Serra, Laura; Sáez Zafra, Marc; Juan, Pablo; Varga, Diego; Mateu, Jorge Springer (2013-11)Wildfires have been studied in many ways, for instance as a spatial point pattern or through modeling the size of fires or the relative risk of big fires. Lately a large variety of complex statistical models can be fitted ... -
Air Quality Trend of PM10. Statistical Models for Assessing the Air Quality Impact of Environmental Policies
Vicente, Ana Belen; Juan, Pablo; Meseguer Costa, Sergio; Serra, Laura; Trilles, Sergio MDPI (2019)A statistical modelling of PM10 concentration (2006–2015) is applied to understand the behaviour, to know the influence of the variables to exposure risk, to treat the missing data to evaluate air quality, and to estimate ... -
Bayesian spatio-temporal prediction of cancer dynamics
Vlad, Iulian T.; Juan, Pablo; Mateu, Jorge Elsevier (2015-09)In this paper we analyze the spatio-temporal dynamics of brain tumors. These objects are originally processed from computer tomography images, and can be depicted as a collection of image pixels with varying degrees of ... -
Data on CO2, temperature and air humidity records in Spanish classrooms during the reopening of schools in the COVID-19 pandemic
Trilles, Sergio; Juan, Pablo; Chaudhuri, Somnath; Vicente, Ana Belen Elsevier (2021-10-17)In order to reduce the advance of the pandemic produced by COVID-19, many actions and restrictions have been applied and the field of education has been no exception. In Spain, during the academic year 2020–2021, face-to-face ... -
Geostatistical methods to identify and map spatial variations of soil salinity
Juan, Pablo; Mateu, Jorge; Jordán Vidal, Manuel Miguel; Mataix-Solera, Jorge; Meléndez-Pastor, I.; Navarro Pedreño, José Elsevier (2011-01)The problem of estimating and predicting spatial distribution of a spatial stochastic process, observed at irregular locations in space, is considered in this paper. Environmental variables usually show spatial dependencies ... -
Hierarchical spatial modeling of the presence of Chagas disease insect vectors in Argentina. A comparative approach
Juan, Pablo; Díaz-Avalos, Carlos; Mejía-Domínguez, Nancy R.; Mateu, Jorge Springer Verlag (2016)We modeled the spatial distribution of the most important Chagas disease vectors in Argentina, in order to obtain a predictive mapping method for the probability of presence of the vector species. We analyzed both the ... -
Integración de modelos medioambientales en infraestructuras de datos espaciales: Un caso de uso en predicción de incendios
Trilles, Sergio; Juan, Pablo; Díaz Sánchez, Laura; Huerta, Joaquin Institut Cartogràfic de Catalunya (2012-02)Hoy en día los incendios forestales son unas de las principales amenazas medioambientales más crecientes a las que nos exponemos [2]. Esto produce la pérdida de bienes humanos y lo que es peor, la destrucción de la parte ... -
Integration of Environmental Models in Spatial Data Infrastructures: A Use Case in Wildfire Risk Prediction
Trilles, Sergio; Juan, Pablo; Díaz, Laura; Aragó Galindo, Pau; Huerta, Joaquin Institute of Electrical and Electronics Engineers (IEEE) (2013)Achieving sustainable growth in our society implies monitoring our environment in order to measure human impact and detect relevant changes and detrimental driving factors such as wildfires and desertification. In order ... -
Pinpointing spatio-temporal interactions in wildfire patterns
Juan, Pablo; Mateu, Jorge; Sáez Zafra, Marc Springer-Verlag (2012-12)The spatial and spatio-temporal patterns of wildfire incidence and their relationship to various geographical and environmental variables are analyzed. Such relationships may be treated as components in particular point ... -
Reliability Evaluation of the Data Acquisition Potential of a Low-Cost Climatic Network for Applications in Agriculture
Trilles, Sergio; Juan, Pablo; Díaz-Avalos, Carlos; Ribeiro, Sara; Painho, Marco MDPI (2020)Temperature, humidity and precipitation have a strong influence on the generation of diseases in different crops, especially in vine. In recent years, advances in different disciplines have enabled the deployment of sensor ... -
Reliability Validation of a Low-Cost Particulate Matter IoT Sensor in Indoor and Outdoor Environments Using a Reference Sampler
Trilles, Sergio; Vicente, Ana Belen; Juan, Pablo; Ramos, Jose Francisco; Meseguer Costa, Sergio; Serra, Laura MDPI (2019)A suitable and quick determination of air quality allows the population to be alerted with respect to high concentrations of pollutants. Recent advances in computer science have led to the development of a high number of ... -
Significance tests for covariate-dependent tredns in inhomogeneous spatio-temporal point processes
Díaz-Avalos, Carlos; Juan, Pablo; Mateu, Jorge Springer Verlag (2014-03)Modeling and inference for spatial and spatio-temporal point processes is an issue that has been broadly investigated in the last years. Application fields such as forestry, epidemiology and ecology have been the main ... -
Similarity measures of conditional intensity functions to test separability in multidimensional point processes
Díaz-Avalos, Carlos; Juan, Pablo; Mateu, Jorge Springer-Verlag (2013-07)Separability in the context of multidimensional point processes assumes a multiplicative form for the conditional intensity function. This hypothesis is especially convenient since each component of a separable process may ... -
Space.time interpolation of daily air temperatures
Sáez Zafra, Marc; Barceló, M.A.; Tobías, Aurelio; Varga, Diego; Ocaña-Riola, R.; Juan, Pablo; Mateu, Jorge UCLA Department of Statistics (2012)We propose a model to describe the mean function as well as the spatio-temporal covariance structure of 15 years of both maximum and minimum daily temperature data from 190 stations throughout the region of Catalonia ... -
