Predicting Performance of Hall Effect Ion Source Using Machine Learning
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.This study introduces HallNN, a machine learning tool for predicting Hall effect ion source performance using a neural network ensemble trained on data generated from numerical simulations. HallNN provides faster and more accurate predictions than numerical methods and traditional scaling laws, making it valuable for designing and optimizing Hall ...

global study of hot flow anomalies using Cluster multi-spacecraft
measurements, Ann. Geophys., 27, 2057-2076,
https://doi.org/10.5194/angeo-27-2057-2009, 2009, 2018 Hot flow anomalies (HFAs) are studied using observations of the magnetometer and the plasma instrument aboard the four Cluster spacecraft. We study several specific features of tangential discontinuities on the basis of Cluster measurements from the time periods of February-April 2003, December 2005-April 2006 and January-April 2007, when the ...

Archaeological Prospection, EarlyView.ABSTRACT Temperate river floodplains present a significant challenge for archaeologists, as cultural and palaeoenvironmental remains are often difficult to locate but can be exceptionally well preserved, especially where groundwater levels are high. In these alluvial environments, the deposition of thick, fine‐grained sediments has potential to deeply ...

Batteries &Supercaps, EarlyView.A model for blend electrodes is developed, parameterized, and validated using experimental data from a SiOx/Gr electrode. The model provides information about local states, such as the degree of lithiation or material‐specific C‐rates, distinguishing between the two active materials.

First Cluster results of the magnetic field structure of the mid- and high-altitude cusps [PDF]
Annales Geophysicae, 2001 Magnetic field measurements from the four Cluster spacecraft from the mid- and high-altitude cusp are presented. Cluster underwent two encounters with the mid-altitude cusp during its commissioning phase (24 August 2000). Evidence for field-aligned

Statistically determined dispersion relations of magnetic field fluctuations in the terrestrial foreshock [PDF]
, 2016 We obtain dispersion relations of magnetic field fluctuations for two crossings of the terrestrial foreshock by Cluster spacecraft. These crossings cover plasma conditions which differ significantly in their plasma $\beta$ but not in the properties of the encountered ion population, both showing shell-like distribution function.
