Análisis mercado eléctrico español
The electricity sector is a very important part of the gross domestic product of a country, besides this, it is a very good indicator of the economic health of any state, and Spain it is not an exception. For this reason ... -
Aplicación del aprendizaje profundo para la predicción de caudal frente a escenarios de inundación del río Arga
La modelización del caudal en cuencas hidrográficas de rápido flujo es un problema altamente complejo en el que los modelos hidrológicos comúnmente utilizados a menudo tienen limitaciones. La existencia de una predicción ... -
Crop classification based on temporal signatures of Sentinel-1 observations over Navarre province, Spain
Crop classification provides relevant information for crop management, food security assurance and agricultural policy design. The availability of Sentinel-1 image time series, with a very short revisit time and high spatial ... -
Crop type mapping based on Sentinel-1 backscatter time series
The high revisit time of Sentinel-1 (S1) observations enables the design of crop type mapping approaches exploiting the backscatter time series observed for the different crops. The objective of this study is to propose a ... -
Detecting intentional herding: what lies beneath intraday data in the Spanish stock market
This paper examines the intentional herd behaviour of market participants, using Li´s test to compare the probability distributions of the scaled cross-sectional deviation in returns in the intraday market with the ... -
Elaboración de una base de datos de áreas pseudoinvariantes (API) en Europa mediante imágenes multitemporales MODIS para la mejora de procesos de corrección radiométrica
Los modelos simplificados de corrección radiométrica que utilizan valores de referencia de la reflectividad de cubiertas invariantes en largos periodos de tiempo, definidos como áreas pseudoinvariantes (API), permiten ... -
The information environment, informed trading and volatility
The relation between informed trading and volatility is analyzed using the change in the proportion of informed transactions calculated through the probability of informed trading variable. The analysis relates to the ... -
Inter-comparison of atmospheric correction methods on Sentinel-2 images applied to croplands
Atmospheric correction of high resolution satellite scenery is a necessary preprocessing step for applications where bottom of atmosphere (BOA) reflectances are needed. The selection of the best atmospheric correction ... -
Large-scale unsupervised spatio-temporal semantic analysis of vast regions from satellite images sequences
Temporal sequences of satellite images constitute a highly valuable and abundant resource for analyzing regions of interest. However, the automatic acquisition of knowledge on a large scale is a challenging task due to ... -
New methodology for wheat attenuation correction at C-Band VV-polarized backscatter time series
Wheat is one of the most important crops worldwide, and thus the use of remote sensing data for wheat monitoring has attracted much interest. Synthetic Aperture Radar (SAR) observations show that, at C-band and VV polarization, ... -
On the performances of trend and change-point detection methods for remote sensing data
Detecting change-points and trends are common tasks in the analysis of remote sensing data. Over the years, many different methods have been proposed for those purposes, including (modified) Mann-Kendall and Cox-Stuart ... -
Relleno de huecos en series temporales de índices Sentinel-2 en cubiertas agrícolas con datos procedentes de Sentinel-1
La teledetección ofrece la posibilidad de realizar un seguimiento del desarrollo de los cultivos mediante la adquisición de imágenes de forma repetida por sensores alojados en plataformas satelitales. El objetivo del ... -
Utilidad de los parámetros fenológicos derivados de series temporales de índices de vegetación de Sentinel-2 para determinar la fecha de cosecha de cereal
La escasez de agua crónica en España, agravada por sequías frecuentes debido al cambio climático, ha causado problemas económicos importantes, con un pago récord de 406,2 millones de euros por parte de Agroseguro a los ...
