Calculation of atomic integration data

Journal of Computational Chemistry, 2000
The calculation of average properties of atoms in molecules and interatomic surfaces is a difficult problem that requires the evaluation of two- and three-dimensional integrals over regions with nontrivial borders. A mathematical formalism is presented that maps these regions onto the whole of ℝ2 and/or ℝ3 and allows the construction of efficient and ...

Atom web portal for atomic data and computation

2021
We have designed a web portal that is able to provide the scientific community with easily accessible high-quality atomic transition data. The application codes used for the portal are capable of calculating a very broad range of atomic properties to answer the significant needs of atomic, plasma, and astrophysics communities. ☐ There is a demonstrated

Uncertainties on Atomic Data

Fusion Science and Technology, 2013
AbstractThere have been long outstanding requests from the modeling community for uncertainty estimates on atomic data. This paper outlines a systematic approach from fundamental atomic structure and collisional calculations, through to well-known spectral diagnostic lines, correlating the uncertainties from each contributing process.

Linguistic support for atomic data types

ACM Transactions on Programming Languages and Systems, 1988
The problems of concurrency and failures in distributed systems can be addressed by implementing applications in terms of atomic data types: data types whose objects provide serializability and recoverability for transactions using them. The specifications of the types can be used to permit high levels of concurrency among transactions while still ...

Atomic Tin Data

2010
A spectrum of Sn in the region around 135 A arises from transitions in Sn ions with the 4d electrons in the ground configuration. Because of the very complex structure of these transitions, the spectrum is largely unknown. Only four lines were identified in Sn XIV, where the ground configuration is 4p64d.

Atomic Data for Titanium

Physica Scripta, 1991
In order to carry out a computer model of a non-LTE plasma, data for a variety of processes for several stages of ionization are needed. A recently developed set of computer codes has been used to calculate such data for all ionization stages of titanium.

Python shared atomic data types

Software: Practice and Experience, 2023
AbstractAlthough atomicity plays a key role in data operations of shared variables in parallel computation, researchers haven't treated atomicity in Python in much detail. This study provides a novel approach to integrate the CPU‐based atomic C APIs into Python shared variables by C Foreign Function Interface for Python (CFFI) on all major platforms ...

Atomic and Molecular Data

1988
The Commission has, since its inception, been devoted to the continually increasing needs of astronomy and astrophysics for reliable atomic and molecular data a) for diagnostic interpretation of astronomical observations, and b) for support of theoretical modelling of astrophysical situations. At the 1985 Delhi General Assembly, the Commission reviewed
