Resonant Absorption in the AGN spectra emerging from photoionized gas: differences between steep and flat ionizing continua [PDF]
, 1998 We present photoionization models accounting for both photoelectric and resonant absorption. Resonance absorption lines from C, O, Ne, Mg, Si S and Fe between 0.1 and 10 keV are treated.

Toroidal modeling of penetration of the resonant magnetic perturbation field [PDF]
, 2013 A toroidal, quasi-linear model is proposed to study the penetration dynamics of the resonant magnetic perturbation (RMP) field into the plasma. The model couples the linear, fluid plasma response to a toroidal momentum balance equation, which includes ...

Timoshenko beam effect in flexural resonant column tests
Soils and Foundations, 2019 Abstract Current methods for deriving Young’s modulus (E) from flexural resonant column tests do not account for the Timoshenko beam effect. Hence, the extent of the Timoshenko beam effect is investigated in this study using a series of numerical experiments performed by finite element program LS-DYNA.
