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 ...

Deep learning-based solid component measuring enabled interpretable prediction of tumor invasiveness for lung adenocarcinoma

Jiancheng Yang, Li Zhang, Xinchao Wang, Hua Sun

Background: The nature of the solid component of subsolid nodules (SSNs) can indicate tumor pathological invasiveness. However, preoperative solid component assessment still lacks a reference standard.Methods: In this retrospective study, an AI algorithm w ...

Improvements in Resolution of 1H NMR of Solids

David Lyndon Emsley, Bruno Simões de Almeida

Magic angle spinning (MAS) in 1H NMR has allowed progress from featureless spectra in static samples to linewidths of a few hundreds of Hertz for powdered solids at the fastest spinning rates available today (100-150 kHz). While this is a remarkable improv ...

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 ...

Design of an intake and a thruster for an atmosphere-breathing electric propulsion system

Francesco Romano, Thomas Binderup Jensen

Challenging space missions include those at very low altitudes, where the atmosphere is the source of aerodynamic drag on the spacecraft, that finally defines the mission's lifetime, unless a way to compensate for it is provided. This environment is named ...

Re-entry analysis of critical components and materials for design-for-demise techniques

Pénélope Leyland, Stefano Mischler, Seong-Hyeon Park

The concern caused by the rising population of space debris has increased. One of the recommended mitigation measures is the safe re-entry disposal either in a controlled or uncontrolled manner. Performing a controlled re-entry, where the spacecraft is gui ...

Optimal Thrust Vector Control of an Electric Small-Scale Rocket Prototype

Colin Neil Jones, Roland Schwan, Petr Listov

Recent advances in Model Predictive Control (MPC) algorithms and methodologies, combined with the surge of computational power of available embedded platforms, allows the use of real-time optimization-based control of fast mechatronic systems. This paper p ...

Kinetics of mixing-water repartition in UHPFRC paste and its effect on hydration and microstructural development

Eugen Brühwiler, Karen Scrivener, Emmanuel Denarié, Arnaud Charles Albert Muller, Mohammadhadi Kazemi Kamyab

The hydration of an ultra-high performance fibre reinforced concrete (UHPFRC) paste with a water to cement ratio of 0.18 was followed by proton nuclear magnetic resonance (1H NMR) alongside more classical techniques for hydration kinetics, and microstructu ...
