(MDPI, 2021)This study presents a thermal analysis of a temperature-driven microfluidic cell through a nonlinear self-adaptive micro valve that provides the mechanisms for the system to maintain a given critical temperature in an ... -
A data-driven method for unsupervised electricity consumption characterisation at the district level and beyond
(Elsevier, 2021)A bottom-up electricity characterisation methodology of the building stock at the local level is presented. It is based on the statistical learning analysis of aggregated energy consumption data, weather data, cadastre, ... -
Soil Quality Assessment after 25 Years of Sewage Sludge vs. Mineral Fertilization in a Calcareous Soil
(MDPI, 2021)The aim of this work was to identify the most sensitive soil quality indicators and assess soil quality after long-term application of sewage sludge (SS) and conventional mineral fertilization for rainfed cereal production ... -
Can Different Salt Formulations Revert the Depressing Effect of Salinity on Maize by Modulating Plant Biochemical Attributes and Activating Stress Regulators through Improved N Supply?
(MDPI, 2021)Salinity is a major constraint in improving agricultural productivity due to its adverse impact on various physiological and biochemical attributes of plants, and its effect on reducing nitrogen (N) use efficiency due to ... -
Full-color multiplexed reflection hologram of diffusing objects recorded by using simultaneous exposure with different times in photopolymer Bayfol® HX
(Elsevier, 2021)An optimized wavelength multiplexing procedure for color reflection holograms of diffusing objects recorded in Bayfol® HX photopolymer is proposed. It is based on simultaneous initial illumination of all the wavelengths ... -
Baseline Energy Use Modeling and Characterization in Tertiary Buildings Using an Interpretable Bayesian Linear Regression Methodology
(MDPI, 2021)Interpretable and scalable data-driven methodologies providing high granularity baseline predictions of energy use in buildings are essential for the accurate measurement and verification of energy renovation projects ... -
Data-Driven Virtual Replication of Thermostatically Controlled Domestic Heating Systems
(MDPI, 2021)Thermostatic load control systems are widespread in many countries. Since they pro vide heat for domestic hot water and space heating on a massive scale in the residential sector, the assessment of their energy performance ... -
Combined simulation and optimization framework for irrigation scheduling in agriculture felds
(Springer, 2021)In the context of growing evidence of climate change and the fact that agriculture uses about 70% of all the water available for irrigation in semi-arid areas, there is an increasing probability of water scarcity scenarios. ... -
Impacts of tillage and nutrient management on soil porosity trends in dryland agriculture
(Wiley, 2021)In dryland Mediterranean semi-arid areas, the use of slurries and no-till are encouraged to reduce costs. This paper evaluates the effect of such practices in terms of morphological changes of the topsoil porosity. The ... -
Intercropping of peanut–tea enhances soil enzymatic activity and soil nutrient status at different soil profiles in Subtropical Southern China
(MDPI, 2021-04-27)Intercropping is one of the most widely used agroforestry techniques, reducing the harmfulimpacts of external inputs such as fertilizers. It also controls soil erosion, increases soil nutrientsavailability, and reduces ... -
Deep genetic structure at a small spatial scale in the endangered land snail Xerocrassa montserratensis
(Nature Research, 2021-04-23)Species with small geographic ranges do not tend to have a high genetic structure, but some land snail species seem to be an exception. Xerocrassa montserratensis, an endangered land snail endemic to Catalonia (northeastern ... -
