The new research on intrinsic correlation between the fraction of liquid-like zones and the beta-relaxation in high-entropy metallic glasses
Researchers Y. J. Duan, E. Pineda and D. Crespo, from the Group of Materials Characterization of the UPC, have made new progress to understand the mechanical properties of high-entropy metallic glasses. The work clarifies the correlation between the fraction of liquid-like zones, i.e. the fraction of atoms that can easily rearrange under the effect of external forces, and the secondary or β relaxation observed in these materials. Besides, the work reveals the high-entropy effect on the supercooled liquid dynamics of the metallic melt.

Manuel Mateos Villar defends his doctoral thesis on the prediction of aircraft trajectories in the pre-tactical phase using machine learning techniques
Manuel Mateos Villar defended his doctoral thesis, with industrial doctorate mention, co-supervised by Xavier Prats (UPC) and Oliva Garcia (Nommon Solutions and Technologies), entitled "Machine Learning for Aircraft Trajectory Prediction: a Solution for Pre-tactical Air Traffic Flow Management". The thesis presents a solution for traffic prediction in the pre-tactical phase that improves the predictive exercise of the current tool (PREDICT) and is able to deal with the entire set of flights in the ECAC network in a way computationally efficient. To do this, different trajectory prediction approaches based on machine learning models trained on historical data have been explored.
