Cost-effectiveness of Opportunity Charging in Non-electrified Railway Lines
(IEEE, 2021)
This paper analyses the cost-effectiveness of deploying opportunity charging points in long-distance non-electrified railway lines, which are driven by battery-based hybrid diesel-electric railway vehicles. A study case ...
Resonant Dual Active Bridge Partial Power Converter for Electric Vehicle Fast Charging Stations
(IEEE, 2021)
This paper presents an analysis and design of a DC-DC charging unit for an electric vehicle fast charging station. Due to the benefits that partial power processing achieves in terms of size reduction and efficiency ...
Characterization of Ti64 forging friction factor using ceramic coatings and different contact conditions
(Elsevier, 2017)
Hot forging processes are highly influenced by the contact conditions between the billet and the dies. A wrong definition of the contact conditions may lead to wrong predictions of the final component geometry, the quantity ...
Una aproximación conceptual para la definición de la mediación digital consensuada en edades tempranas
(Universidad de Sevilla, Grupo de Investigación Didáctica. Análisis tecnológico y cualitativo de los procesos de enseñanza-aprendizaje, 2022)
Ante la creciente tendencia del uso de las tecnologías digitales en la primera infancia y la falta de claridad entre la comunidad científica, son cada vez más las personas, agentes e instituciones alarmadas por cómo su uso ...
Influence of tool wear on residual stresses when turning Inconel 718
(Elsevier, 2016)
This paper analyzes the effect of tool wear on residual stresses when turning. Inconel 718 discs were machined for prolonged periods at several cutting speeds, feed-rates and depth of cut. Tests were interrupted to measure ...
Effect of innovative finishing operations on the tribological performance of steel 27MnCr5
(Elsevier Ltd., 2022)
Transmission shafts used in the automotive sector must have a good tribological performance, and therefore an enhanced surface integrity. This paper aims to study the effect of eco-friendly innovative finishing operations ...
Enhancing surface integrity of A7050-T7451 aluminium alloy by pneumatic machine hammer peening
