Line Profiles in Symbiotic Stars
Astrophysics and Space Science, 1986High resolution profiles of permitted and forbidden lines in symbiotic stars are described, with particular reference to the broad wings. An interpretation of the data in terms of an optically thin accretion disc around a hot subdwarf is presented.

Modeling of Geometric Variations for Line-Profiles
Volume 5: 37th Design Automation Conference, Parts A and B, 2011The geometric variations in a tolerance-zone can be modeled with hypothetical point-spaces called Tolerance-Maps (T-Maps) for purposes of automating the assignment of tolerances during design. The objective of this paper is to extend this model to represent tolerances on line-profiles.

Line profile-based fingerprint matching
2016 International Workshop on Computational Intelligence (IWCI), 2016Traditional fingerprint matching algorithms primarily focus on minutiae points on fingertip surface. In this paper, a novel approach is proposed for fingerprint matching that is based on ridge and valley characteristics of fingerprints. At first, the input fingerprint image is normalized and the registration point of that particular fingerprint is ...

Line-profile measurement of xerographic copy
Applied Optics, 1978An algorithm is presented which permits easy and rapid characterization of lines typically observed in xerographic copy. The outputs of the algorithm are line edge width, line width, and peak density. Auxiliary outputs are line darkness and spatial frequency content.

Nonthermal effects on hydrogen-line profiles
Physical Review A, 1985Experimentally determined level populations of hydrogen excited states from a low-density Z pinch are used as initial conditions in a simulation to derive electron-velocity distributions. These velocity distributions show excess electrons in the high velocity end of the distribution when compared to a Maxwellian velocity distribution.

Protein profile of the HeLa cell line
Journal of Chromatography A, 2004HeLa cells are widely used for all kinds of in vitro studies in biochemistry, biology and medicine. Knowledge on protein expression is limited and no comprehensive study on the proteome of this cell type has been reported so far. We applied proteomics technologies to analyze the proteins of the HeLa cell line.

Solar Physics, 1984
It is shown that comparing an observed Fraunhofer profile to a fitted gaussian yields more information on shape and asymmetry of the solar line than the simple bisector method.

The Interpretation of Line Profiles
International Astronomical Union Colloquium, 1977Observations of the shapes and intensities of spectral lines provide a bounty of information about the outer layers of the sun. In order to utilize this information, however, one is faced with a seemingly monumental task. The sun’s chromosphere and corona are extremely complex, and the underlying physical phenomena are far from being understood ...
