Interpretative 3D MHD modelling of deuterium SPI into a JET H-mode plasma

Cristian Sommariva, Umar Sheikh, Haomin Sun, Mengdi Kong

The pre-thermal quench (pre-TQ) dynamics of a pure deuterium ( D 2 ) shattered pellet injection (SPI) into a 3 MA / 7 MJ JET H-mode plasma is studied via 3D non-linear MHD modelling with the JOREK code. The interpretative modelling captures the overall evo ...

Covariant formulation of relativistic mechanics

Miguel Alexandre Ribeiro Correia

Accretion disks surrounding compact objects, and other environmental factors, deviate satellites from geodetic motion. Unfortunately, setting up the equations of motion for such relativistic trajectories is not as simple as in Newtonian mechanics. The prin ...

A Dynamic Multi-Region MFD Model for Ride-Sourcing Systems with Ridesplitting

Nikolaos Geroliminis, Caio Vitor Beojone

Dynamic network-level models directly addressing ride-sourcing services can be useful for the development of efficient traffic management strategies both for city and company operators. Recent developments presented models under equilibrium situations for ...

Acoustic emission techniques for the detection of simulated failures in historical vehicles engines

Stefano Mischler, Laura Brambilla

Technical and industrial heritage artefacts are characterized by the presence of mechanisms. The possibility to activate, or reactivate, these mechanisms is an integral part of the cultural values of this kind of patrimony. The artefacts' functionality, ho ...

Multiple-Station Measurements of a Return-Stroke Electric Field From Rocket-Triggered Lightning at Distances of 68-126 km

Antonio Sunjerga, Qi Li, Mi Zhou

Far-field measurements of lightning-produced electromagnetic fields are of high importance for lightning location systems. Data from recorded lightning strokes can be, for example, used to assess the risk of lightning-induced damage in some geographical ar ...
