Spatio-Temporal Modeling of Zika and Dengue Infections within Colombia
2018
The aim of this study is to estimate the parallel relative risk of Zika virus disease (ZVD) and dengue using spatio-temporal interaction effects models for one department and one city of Colombia during the 2015&ndash
Cartografía de vulnerabilidad frente a inundaciones en llanos mediterráneos. Caso de estudio del Barranc de Carraixet y Rambla de Poyo
2008
Este trabajo aborda la cartografía de vulnerabilidad frente a inundaciones, en dos pequeños llanos mediterráneos pertenecientes al Barranc de Carraixet y la Rambla de Poyo. Ambos forman parte del Área Metropolitana de Valencia, integrando las comarcas de l¿Horta Nord y l¿Horta Sud, respectivamente. Constituye un ensayo metodológico, basado en estimadores socioeconómicos sencillos, obtenidos a partir de los usos del suelo. La vulnerabilidad se evalúa en función del valor económico del suelo y de la exposición humana al peligro. El valor económico del suelo se calcula a partir del Catastro. La exposición se calcula para tres supuestos de densidad de ocupación del espacio en función de la fran…
Quantification of synmagmatic flow structures: a tool for Rock Quality Evaluation
2013
The result of the analysis using methods based on fractal geometry provides information about magmatic flux directions and mineral equilibrium processes in the crystallizing magma chamber. Additionally, the used methods may also provide important information for the rock industry, because they allow a fast and automatically evaluation of rock quality.
Flexible Spare Core Placement in Torus Topology based NoCs and its validation on an FPGA
2021
In the nano-scale era, Network-on-Chip (NoC) interconnection paradigm has gained importance to abide by the communication challenges in Chip Multi-Processors (CMPs). With increased integration density on CMPs, NoC components namely cores, routers, and links are susceptible to failures. Therefore, to improve system reliability, there is a need for efficient fault-tolerant techniques that mitigate permanent faults in NoC based CMPs. There exists several fault-tolerant techniques that address the permanent faults in application cores while placing the spare cores onto NoC topologies. However, these techniques are limited to Mesh topology based NoCs. There are few approaches that have realized …
Active macro-zones algorithm via multidomain SBEM for strain-hardening elastoplastic analysis
2010
In this paper a strategy to perform strain-hardening elastoplastic analysis by using the Symmetric Boundary Element Method (SBEM) for multi-domain type problems is shown. The procedure has been developed inside Karnak.sGbem code by introducing an additional module.
Elastoplastic analysis for active macro-zones via multidomain symmetric Galerkin BEM
2010
In this paper a strategy to perform elastoplastic analysis by using the Symmetric Boundary Element Method (SBEM) for multidomain type problems is shown. This formulation uses a self-stresses equation to evaluate the trial stress in the predictor phase, and to provide the elastoplastic solution in the corrector one. Since the solution is obtained through a return mapping involving simultaneously all the plastically active bem-elements, the proposed strategy does not depend on the path of the plastic strain process and it is characterized by computational advantages due the considerable decrease of the plastic iterations number. This procedure has been developed inside Karnak.sGbem code [1] b…
Assessing the performance of a large-scale irrigation system by estimations of actual evapotranspiration obtained by Landsat satellite images resampl…
2019
Abstract Remote sensing techniques allow monitoring the Earth surface and acquiring worthwhile information that can be used efficiently in agro-hydrological systems. Satellite images associated to computational models represent reliable resources to estimate actual evapotranspiration fluxes, ETa, based on surface energy balance. The knowledge of ETa and its spatial distribution is crucial for a broad range of applications at different scales, from fields to large irrigation districts. In single plots and/or in irrigation districts, linking water volumes delivered to the plots with the estimations of remote sensed ETa can have a great potential to develop new cost-effective indicators of irr…
Una aproximación volumétrica a la desagregación espacial de la población combinando cartografía temática y datos LIDAR
2016
La disponibilidad de información sobre la distribución de la población a gran escala, e independiente de las unidades administrativas de recogida de la información, es una necesidad en muchos ámbitos: evaluación de riesgos de terremotos, inundaciones o incendios, integración de estadísticas demográficas con información medioambiental en formatos diversos, diseño de políticas de prestación de servicios públicos o estudios de accesibilidad y movilidad en las grandes ciudades. Por estas razones, la literatura ha explorado numerosos métodos de desagregación de la población, recogida a nivel municipal o de sección censal, en polígonos urbanos procedentes de los sistemas de información de cobertu…
A population density grid for Spain
2013
This article describes a high-resolution land cover data set for Spain and its application to dasymetric population mapping (at census tract level). Eventually, this vector layer is transformed into a grid format. The work parallels the effort of the Joint Research Centre (JRC) of the European Commission, in collaboration with Eurostat and the European Environment Agency (EEA), in building a population density grid for the whole of Europe, combining CORINE Land Cover with population data per commune. We solve many of the problems due to the low resolution of CORINE Land Cover, which are especially visible with Spanish data. An accuracy assessment is carried out from a simple aggregation of …
Updated Field Synopsis and Systematic Meta-Analyses of Genetic Association Studies in Cutaneous Melanoma: The MelGene Database
2015
We updated a field synopsis of genetic associations of cutaneous melanoma (CM) by systematically retrieving and combining data from all studies in the field published as of August 31, 2013. Data were available from 197 studies, which included 83,343 CM cases and 187,809 controls and reported on 1,126 polymorphisms in 289 different genes. Random-effects meta-analyses of 81 eligible polymorphisms evaluated in4 data sets confirmed 20 single-nucleotide polymorphisms across 10 loci (TYR, AFG3L1P, CDK10, MYH7B, SLC45A2, MTAP, ATM, CLPTM1L, FTO, and CASP8) that have previously been published with genome-wide significant evidence for association (P5 × 10(-8)) with CM risk, with certain variants pos…
