NLTE Analysis of High-Resolution H-Band Spectra, V: Neutral Sodium
Universe, 2023 In order to derive sodium abundances and investigate the effects of non-local thermodynamic equilibrium (NLTE) on the formation of H-band Na I lines, we update the sodium atomic model by incorporating collision rates with hydrogen from new quantum ...

Animation of Flocks Flying in Line Formations [PDF]
Artificial Life, 2011 We provide a biologically motivated technique for modeling and animating bird flocks in flight, which produces plausible and realistic-looking flock animations. While most previous approaches have focused on animating cluster formations, this article introduces a technique for animating flocks that fly in certain patterns, so-called line formations. We

coiling as a linear value for making ceramic wall tiles
Journal of Architecture, Art & Humanistic Science, 2021 There are many materials that are used in wall tiles such as marble, granite and other materials used, and ceramic tiles remain the best solution because of its material used in it, which is a clay that has high flexibility, which makes it a rich ...

Iteration factors in the line formation problem with frequency dependent source function [PDF]
Serbian Astronomical Journal, 2010 In this paper some iteration factors families introduced previously to solve the pure line transfer problem are generalized to the case when the back- ground continuum is taken into account.

Mixing state of oxalic acid containing particles in the rural area of Pearl River Delta, China: implications for the formation mechanism of oxalic acid [PDF]
Atmospheric Chemistry and Physics, 2017 The formation of oxalic acid and its mixing state in atmospheric particulate matter (PM) were studied using a single-particle aerosol mass spectrometer (SPAMS) in the summer and winter of 2014 in Heshan, a supersite in the rural area of the Pearl ...

Review of Rydberg Spectral Line Formation in Plasmas
Atoms, 2023 The present review is dedicated to the problem of an array of transitions between highly-excited atomic levels. Hydrogen atoms and hydrogen-like ions in plasmas are considered here. The presented methods focus on calculation of spectral line shapes. Fast

Planetesimal formation starts at the snow line [PDF]
, 2017 Context. The formation stage of planetesimals represents a major gap in our understanding of the planet formation process. Late-stage planet accretion models typically make arbitrary assumptions about planetesimal and pebble distribution, while dust ...

Counting Critical Formations on a Line
SIAM Journal on Control and Optimization, 2014 Formation shape control for a collection of point agents is concerned with devising decentralized control laws which ensure that the formation will move so that certain interagent distances approximate prescribed values as closely as possible.

Stark Broadening of Neutral Boron Lines
Atoms, 2019 Stark broadening parameters, width and shift, of lines within B I 2s22p−2s2ns spectral series have been calculated. Semi-classical theory in impact approximation has been applied. Temperature dependence of Stark parameters has been studied.
