Electric Vehicles (EVs) appear as an environmental solution for transport sector since they emit zero emissions while driving. Nonetheless, the carbon intensity (CI) of the energy sources involved in the electricity generation system could seriously compromise this solution. Hence, this study proposes a methodology to verify the sustainability of t...

Due to the pandemic provoked by COVID-19 in March 2020, the Polytechnic University of Valencia (UPV), following the Government's guidelines, changed the modality of the formal lectures from face-to-face to online teaching. Professors and students had the challenge of adapting to the new model to continue the semester. In this paper, the results of...

In the so-called society 4.0, Artificial Intelligence (AI) is being widely used in many areas of life. Machine learning uses mathematical algorithms based on "training data", which are able to make predictions or take decisions with the ability to change their behavior through a self-training approach. Furthermore, thanks to AI, a large volume of d...

The serious situation caused by the coronavirus has forced Authorities to take drastic decisions that have affected the normal functioning of the entire society. One of the most impactful measures taken has been the self-discipline of the social distancing as the entire society has been obliged to stay at home. At the education level, restrictions...

Group tutorials are becoming an ever-increasing learning methodology in University education due to the continuous knowledge feedback among students. Despite the positive impact of such kind of sessions on students, their previous organization phase remains most of the times misleading. The traditional way of arranging a group tutorial through e-ma...

In this research work, a 3 kW stove based on biomass gasification, together with a fuel obtained from agriculture wastes as an alternative to the commonly used charcoal, have been developed looking for sustainable cooking in poor communities. Alternative fuel (BSW) are briquettes obtained by carbonization and densification of agricultural solid was...

La docencia inversa, también llamada clase invertida, es una nueva forma metodológica de desarrollo de la actividad docente con un enfoque basado en invertir el esquema tradicional del proceso de aprendizaje y de dar mayor protagonismo al alumnado. La docencia inversa tiene el objetivo de incrementar el compromiso del estudiante y de mejorar su com...

En este paper se aplica la metodología de docencia inversa utilizada en la UPV, a la asignatura de Redes Eléctricas Inteligentes. Tiene especial interés dicha metodología debido a la pandemia producida por COVID-19 y el cambio de actividad académica de presencial a no presencial en la UPV. De acuerdo con el procedimiento, se realiza la presentación...

La educación universitaria está experimentando un proceso de cambio dinámico, desde un sistema de enseñanza tradicional hacia otro más flexible. En este contexto surge la metodología clase inversa, la cual comprende dos fases: conceptual y colaborativa. En la fase conceptual, desarrollada fuera del aula, el estudiante se prepara para la clase a par...

Eighty per cent of the people without access to electricity live in rural areas. Due to high investment costs in the grid, the solution to providing electricity to these people will mainly rely on the installation of islanded hybrid microgrids. Designers need to consider a variety of factors for the optimal design of hybrid microgrids. However, man...
