Hardening prediction of diverse materials using the Digital Image Correlation technique
(Elsevier, 2018)
In recent years, due to the introduction of higher resistance materials in the automotive sector, sheet metal-forming tool-makers have been forced to deal with more challenging process designs. Therefore, the optimisation ...
Fe nanoparticles produced by electric explosion of wire for new generation of magneto-rheological fluids
(IOP Publishing, 2018)
Iron magnetic nanoparticles were produced by the technique of the electric explosion of a wire (EEW). The major crystalline phase (95 ± 1%) was α-Fe with lattice parameter a = 0.2863(3) nm. The size of the coherent diffraction ...

Digital Interferometry Applied to Thermogravitational Technique
(Springer, 2018)
In this work, we have applied Optical Digital Interferometry approach to thermogravitational micro-column technique. By the new analysis, we examine the entire height of the micro-column and determine the complete concentration ...
Performance and internationalization effects of the use of ICT in diversified companies
(Universidad Politécnica de Cartagena, 2018)
The relationship between Information and Communication Technologies (ICT) and business performance has been a topic of great importance for academics from different areas for several decades. In this sense, this study ...
Simple voltage balancing method to protect series-connected devices experimentally verified in a 5L-MPC converter
(IEEE, 2018)
This paper presents a solution for the voltage balance problem of the series-connected devices that can be applied to multilevel converters in which the series-connected devices need to block twice their switched voltage. ...
Optimization of the CRTM process by means of monitoring techniquesOptimización del CRTM mediante técnicas de monitorizado de procesos
(Scipedia, 2018)
In this work the feasability of the monitoring system, composed of flow-rate and injection pressure sensors, in addition to the pressure sensors integrated in the mold, is demonstrated to determine the optimal process ...
Fatigue life prediction of spherical gear couplings
(American Gear Manufacturers Association (AGMA), 2018)
Spherical gear couplings are mechanical components that allow transmitting torque between misaligned shafts by means of equally spaced teeth. For instance, they are used in roll-levelling machines in order to transmit power ...
Influence of thermal distortion on spur gear tooth contact
(American Gear Manufacturers Association (AGMA), 2018)
The reduction of component size and oil volume of current automotive and aeronautical transmissions along with the increasing input speed are pushing gear teeth bulk temperatures to their scuffing limit. Although new ...
Modelizado bidimensional de engranajes cilíndricos por elementos finitos
(UNED, 2018)
El análisis de la distribución de carga, rigidez y error de transmisión de engranajes cilíndricos es fundamental para predecir los efectos de la geometría del dentado sobre las vibraciones, resistencia y eficiencia. El uso ...
