Preference of helicon plasma discharge directionality due to standing waves Open
Helicon plasma has high ionization efficiency. It has been used in semiconductors, space propulsion, and nuclear fusion as a high-density plasma source. This paper establishes a three-dimensional numerical model of argon helicon plasma dis…

This paper is concerned with enhancing the performance of Lasso for squarefree hierarchical polynomial models. We propose a compound crite- rion that combines validation error with a measure of model complexity, and the measure of model co…
