Blue lines as chromospheric diagnostics: The Si I lines at 3906 and 4103 Å
(IOP Publishing, 2001-05)
We present a complete atomic model for Si I line synthesis. We study how the computed profiles of two blue lines of this atom are influenced by the choice of the atomic parameters and find that, although several cross ...
Microlensing in H1413+117: disentangling line profile emission and absorption in a broad absorption line quasar
(2010)
On the basis of 16 years of spectroscopic observations of the four components of the gravitationally lensed broad absorption line (BAL) quasar H1413+117, covering the ultraviolet to visible rest-frame spectral range, we ...
Chemical abundance analysis of the Be star HD 171054
(ELSEVIER SCIENCE BV, 2011)
In this work the results of a spectroscopic study of the southern field narrow-line Be star HD 171054 are presented. High dispersion and signal-to-noise ratio spectra allowed the estimation of the fundamental photospheric ...

Simplified procedure to estimate the resistance parameters of transmission lines
(2013-09-01)
An alternative and simplified procedure is described to estimate the longitudinal resistances of transmission lines based on the real-time load profile. This method proposes to estimate the resistance parameters from the ...
