Impact of Commutation Failure Preventions on HVDC System Based on a Multi-Index Value Set Approach
IEEE Access, 2021 This paper proposes a systematic method, based on rational approximation and value set approach, to unravel the impact of commutation failure preventions (CFPREVs) on HVDC system dynamics.

Stark Broadening from Impact Theory to Simulations
Atoms, 2017 Impact approximation is widely used for calculating Stark broadening in a plasma. We review its main features and different types of models that make use of it.

The Second Workshop on Lineshape Code Comparison: Isolated Lines
Atoms, 2014 In this work, we briefly summarize the theoretical aspects of isolated line broadening. We present and discuss test run comparisons from different participating lineshape codes for the 2s-2p transition for LiI, B III and NV.

Approximating spectral impact of structural perturbations in large networks [PDF]
Physical Review E, 2010 Determining the effect of structural perturbations on the eigenvalue spectra of networks is an important problem because the spectra characterize not only their topological structures, but also their dynamical behavior, such as synchronization and cascading processes on networks.

ZEST: A Fast Code for Simulating Zeeman-Stark Line-Shape Functions
Atoms, 2018 We present the ZEST code, dedicated to the calculation of line shapes broadened by Zeeman and Stark effects. As concerns the Stark effect, the model is based on the Standard Lineshape Theory in which ions are treated in the quasi-static approximation ...

Positron Impact Excitation of the nS States of Atomic Hydrogen
Atoms, 2020 The excitation cross sections of the nS states, n = 2 to 6, of atomic hydrogen at various incident positron energies (10.23 to 300 eV) were calculated using the variational polarized-orbital method.

Focusing of high-energy particles in the electrostatic field of a homogeneously charged sphere and the effective momentum approximation [PDF]
, 2007 The impact of the strongly attractive electromagnetic field of heavy nuclei on electrons in quasi-elastic (e,e') scattering is often accounted for by the effective momentum approximation.

On the Application of Stark Broadening Data Determined with a Semiclassical Perturbation Approach
Atoms, 2014 The significance of Stark broadening data for problems in astrophysics, physics, as well as for technological plasmas is discussed and applications of Stark broadening parameters calculated using a semiclassical perturbation method are analyzed.
