A Bibliometric Analysis of the Health Field Regarding Social Networks and Young People
(MDPI, 2019)Social networks have historically been used to share information and support regarding health-related topics, and this usage has increased with the rise of online social media. Young people are high users of social media, ... -
A Cost-Effective and Efficient Electronic Design for Photovoltaic Systems for Solar Hot Water Production
(MDPI, 2021)A significant percentage of energy consumption in buildings is to produce hot water. Photovoltaic solar heating can be considered a clean and renewable energy option—easy to install, silent, and without maintenance—to ... -
A critical assessment of the dislocation-driven model for superplasticity in yttria tetragonal zirconia polycrystals
(The American Ceramic Society, 2008)In this paper, the origin of the threshold stress in pure 3 mol %-yttria tetragonal zirconia polycrystals (YTZP) is analysed in detail. At this regard, the two explanations reported in literature are discussed thoroughly. ... -
A Discrete-Continuous PSO for the Optimal Integration of D-STATCOMs into Electrical Distribution Systems by Considering Annual Power Loss and Investment Costs
(MDPI, 2022)Currently, with the quick increase in global population, the energetic crisis, the environmental problematic, and the development of the power electronic devices generated the need to include new technologies for supporting ... -
A giant exoplanet orbiting a very-low-mass star challenges planet formation models
(American Association for the Advancement of Science, 2019)Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than gas giants around low-mass stars, as predicted by the core accretion theory of planet formation. We report the discovery of a giant ... -
A Hybrid Water Distribution Networks Design Optimization Method Based on a Search Space Reduction Approach and a Genetic Algorithm
(MDPI, 2017)This work presents a new approach to increase the efficiency of the heuristics methods applied to the optimal design of water distribution systems. The approach is based on reducing the search space by bounding the ... -
A Methodology for Buildings Access to Solar Radiation in Sustainable Cities
(MDPI, 2019)The growing need to improve the environmental and energy sustainability of buildings involves the use of solar radiation incident on their surfaces. However, in cities, this task is complicated due to the constructive ... -
A novel backtracking approach for two-axis solar PV tracking plants
(Elsevier, 2020)Solar tracking is a technique required to increase energy production in multiple photovoltaic (PV) facilities. In these plants, during low-elevation solar angle hours, shadows appear between the collectors causing a dramatic ... -
A Novel Proposal in Wind Turbine Blade Failure Detection: An Integrated Approach to Energy Efficiency and Sustainability
(MDPI, 2024)This paper presents a novel methodology for detecting faults in wind turbine blades using computational learning techniques. The study evaluates two models: the first employs logistic regression, which outperformed neural ... -
A VR Serious Game to Increase Empathy towards Students with Phonological Dyslexia
(IEEE, 2023)Dyslexia is a neurodevelopmental disorder that is estimated to affect about 5-10% of the population. In particular, phonological dyslexia causes problems in connecting the sounds of words with their written forms. This ... -
Actividades para reflexionar sobre los procesos de aprendizaje en la formación inicial del profesorado de enseñanza secundaria
(Universidad de Córdoba, UCOPress, 2014)En este trabajo hemos tratado de conocer cuáles son las concepciones personales en torno al aprendizaje de los alumnos del Máster de Formación del Profesorado de Enseñanza Secundaria de las especialidades de ciencias ... -
Additive-free superhard B4C with ultrafine-grained dense microstructures
(The American Ceramic Society, 2014)A unique combination of high-energy ball-milling, annealing, and spark-plasma sintering has been used to process superhard B4C ceramics with ultrafine-grained, dense microstructures from commercially available powders, ... -
Advancing sustainable education: design a novel steams model integrating technical and psychological factors
(IATED Publications, 2024)Over the past decade, the integration of Science, Technology, Engineering, MathemaICTs, and Social Sciences (STEAM) disciplines into educational models has emerged as a crucial aspect of preparing future generations. This ... -
All-sky brightness monitoring of light pollution with astronomical methods
(Elsevier, 2010)This paper describes a mobile prototype and a protocol to measure light pollution based on astronomical methods. The prototype takes three all-sky images using BVR filters of the Johnson-Cousins astronomical photometric ... -
An All-Sky Transmission Monitor: ASTMON
(IOP Science, 2011)We present here the All-Sky Transmission Monitor (ASTMON), designed to perform a continuous monitoring of the surface brightness of the complete night sky in several bands. The data acquired are used to derive, in addition, ... -
An investigation of an underwater steam plasma discharge as alternative to air plasmas for water purification
(IOP Publishing, 2015)An underwater steam plasma discharge, in which water itself is the ionizing media, is investigated as a means to introduce advanced oxidation species into contaminated water for the purpose of water purification. The steam ... -
Analysis of a kink pair model applied to a peierls mechanism in basal and prism plane slips in sapphire (α-Al2O3) deformed between 200° and 1800°C
(The American Ceramic Society, 2008)A model based on dislocation glide controlled by the nucleation and propagation of kink pairs in a high Peierls stress crystal is revisited and modified to account for changes in dislocation densities and segment lengths ...
