Integrating Domain Knowledge in Data-Driven Earth Observation With Process Convolutions
2022
The modelling of Earth observation data is a challenging problem, typically approached by either purely mechanistic or purely data-driven methods. Mechanistic models encode the domain knowledge and physical rules governing the system. Such models, however, need the correct specification of all interactions between variables in the problem and the appropriate parameterization is a challenge in itself. On the other hand, machine learning approaches are flexible data-driven tools, able to approximate arbitrarily complex functions, but lack interpretability and struggle when data is scarce or in extrapolation regimes. In this paper, we argue that hybrid learning schemes that combine both approa…
La Neología del Turismo 2.0: Análisis de la Creación Léxica y Retos para la Traducción
2018
[EN] This study analyses the lexical neology and the formation of words from anglicisms in the professional language of tourism to gauge their difficulty for translation. To this end, a corpus of tourist management reports has been compiled and through a semi-automatic extraction methodology, the identification and classification of the candidates for neologisms has been carried out to study the most frequently used word formation mechanisms and offer a perspective of these new words that helps the translation of tourism texts.
Temperature-responsive cellulose-based hydrogels as draw agents in Forward Osmosis
2016
Forward Osmosis is a powerful tool to produce clean water at a low cost if appropriate draw agents and regeneration methods are employed (1). In this frame, stimuli-responsive hydrogels are interesting candidates due to their ability to uptake water and release it under physical stimuli, such as hydrostatic pressure and temperature variations. In particular, temperature-responsive hydrogels that are able to absorb large amount of water at room temperature and release it upon a slight temperature increase are very appealing candidates because they can be regenerated easily and with very low energy consumption (2). Chemical stability and biocompatibility are two further requirements that hydr…
Nanofiltration of secondary effluent for wastewater reuse in the textile industry
2008
Abstract Textile industries represent an important environmental problem due to their high water consumption. In many Spanish regions with water scarcity, this fact can be an argument to make wastewater reuse necessary. In this work, a biologically treated wastewater from a cotton thread factory was subjected to nanofiltration (NF) in two ways, direct NF treatment and NF after a pre-treatment stage by ultrafiltration (UF). Nowadays, the factory effluent is treated by an activated sludge process. This effluent has high values of COD (200mgO 2 L −1 ) and TDS (5000mg L −1 ) which makes its use in the textile processes impossible. In such situations, reverse osmosis (RO) has been typically used…
