Efectos de la actividad agraria sobre los recursos hídricos y la erosión del suelo. Análisis y modelado en cuencas experimentales de la zona media de Navarra
(2014)
Tesis doctoral / Doktoretza tesia,
Este trabajo caracteriza el comportamiento hidrológico y erosivo de la cuenca agraria
experimental de La Tejería del valle de Yerri en Navarra, de 164 ha. Se evalúa el
modelo hidrológico de contaminación difusa AnnAGNPS, ...
Diseño, fabricación y ensayo de estructuras autodesplegables de protección al vuelco (AD-ROPS)
(2015)
Tesis doctoral / Doktoretza tesia,
En esta tesis se desarrolla una ROPS (Roll Over Protection Structure) de despliegue automático, diseñado principalmente para tractores estrechos, utilizando infladores de airbag, capaces de aumentar al mismo tiempo la ...
On the added value of quad-pol data in a multi-temporal crop classification framework based on RADARSAT-2 imagery
(MDPI, 2016)
Artículo / Artikulua,
Polarimetric SAR images are a rich data source for crop mapping. However, quad-pol
sensors have some limitations due to their complexity, increased data rate, and reduced coverage
and revisit time. The main objective of ...
Clasificación de cultivos en la zona media de Navarra mediante imágenes radar polarimétricas
(Universidad Politécnica de Valencia, 2010)
Artículo / Artikulua,
Navarra lleva años empleando la técnica de clasificación
supervisada de imágenes multiespectrales
de satélite para la realización de la estadística
agraria. La cubierta nubosa, muy
habitual en esta zona, limita e incluso ...
The added value of stratified topographic correction of multispectral images
(MDPI, 2016)
Artículo / Artikulua,
Satellite images in mountainous areas are strongly affected by topography. Different studies demonstrated that the results of semi-empirical topographic correction algorithms improved when a stratification of land covers ...
Effects of spatial sampling interval on roughness parameters and microwave backscatter over agricultural soil surfaces
(MDPI, 2016)
Artículo / Artikulua,
The spatial sampling interval, as related to the ability to digitize a soil profile with a certain number of features per unit length, depends on the profiling technique itself. From a variety of profiling techniques, ...
Validation of a simplified model to generate multispectral synthetic images
(MDPI, 2015)
Artículo / Artikulua,
A new procedure to assess the quality of topographic correction (TOC) algorithms applied to remote sensing imagery was previously proposed by the authors. This procedure was based on a model that simulated synthetic scenes, ...
Combined spatial and temporal effects of environmental controls on long-term monthly NDVI in the Southern Africa savanna
(MDPI, 2013)
Artículo / Artikulua,
Deconstructing the drivers of large-scale vegetation change is critical to predicting and managing projected climate and land use changes that will affect regional vegetation cover in degraded or threated ecosystems. We ...
Residual stresses with time-independent cyclic plasticity in finite element analysis of welded joints
(MDPI, 2017)
Artículo / Artikulua,
Due to the intense concentration of heat in a reduced area when Gas Metal Arc Welding (GMAW) is used to join mechanical components, the regions near the weld bead are subjected to severe thermal cycles. Firstly, the region ...
Analysis of surface roughness in agricultural soils using in-situ measurements and remote sensing techniques
(2017)
Tesis doctoral / Doktoretza tesia,
El término rugosidad superficial del suelo es utilizado para describir las variaciones de elevación de la superficie del suelo (micro-relieve). La rugosidad afecta diferentes procesos hidrológicos importantes como el ...
