The intrinsic line width of the Fe Ka line of AGN [PDF]
X-ray fluorescent lines are unique features of the reflection spectrum of the cold torus when irradiated by the central AGN. Their intrinsic line widths can be used to probe the line-emitting region. The line widths of the Fe \Ka line measured from the first order Chandra High Energy Grating (HEG) spectra are $3-5$ times larger than those measured with

Monitor variability of millimeter lines in IRC +10216 [PDF]
A single dish monitoring of millimeter maser lines SiS J=14-13 and HCN nu_2 = 1^f J=3-2 and several other rotational lines is reported for the archetypal carbon star IRC+10216. Relative line strength variations of 5%~30% are found for eight molecular line features with respect to selected reference lines.

Fault Location Estimation by Using Machine Learning Methods in Mixed Transmission Lines [PDF]
Overhead lines are generally used for electrical energy transmission. Also, XLPE underground cable lines are generally used in the city center and the crowded areas to provide electrical safety, so high voltage underground cable lines are used together with overhead line in the transmission lines, and these lines are called as the mixed lines.

Leveraging Structural Information to Improve Point Line Visual-Inertial Odometry [PDF]
Leveraging line features can help to improve the localization accuracy of point-based monocular Visual-Inertial Odometry (VIO) system, as lines provide additional constraints. Moreover, in an artificial environment, some straight lines are parallel to each other.

Text line extraction using fully convolutional network and energy minimization [PDF]
Text lines are important parts of handwritten document images and easier to analyze by further applications. Despite recent progress in text line detection, text line extraction from a handwritten document remains an unsolved task. This paper proposes to use a fully convolutional network for text line detection and energy minimization for text line ...

Emission and absorption lines of gamma-ray bursts affected by the relativistic motion of fireball ejecta [PDF]
We display by numerical calculation how rest frame spectral lines appear in the observed spectrum of gamma-ray bursts due to the Doppler effect in the fireball framework. The analysis shows that: a) in the spectrum of a relativistically expanding fireball, all rest frame lines would shift to higher energy bands and would be significantly smoothed; b ...
