Atomic processes in astrophysics

Astrophysics and Space Science, 1996
We review the atomic processes responsible for astrophysical emission line spectra, paying particular attention to the reliability of the rates used to determine the physical conditions in the emitting gas. We discuss particular cases where often-neglected processes play important roles.

Atomicity and isolation for transactional processes

ACM Transactions on Database Systems, 2002
Processes are increasingly being used to make complex application logic explicit. Programming using processes has significant advantages but it poses a difficult problem from the system point of view in that the interactions between processes cannot be controlled using conventional techniques.

Energetics of Surface Atomic Processes

Surface Science, 1990
The energies needed in various surface atomic processes such as surface diffusion, binding of small atomic clusters on the surface, interaction between two adsorbed atoms, dissociation of an atom from a small cluster or from a surface layer, binding of kink site atoms or atoms at different adsorption sites to the surface etc.

Atomicity of batches in stream processing

Journal of Ambient Intelligence and Humanized Computing, 2017
Stream processing is about processing continuous streams of data by programs in a workflow. Continuous execution is discretized by grouping input stream tuples into batches and using one batch at a time for the execution of programs. As source input batches arrive continuously, several batches may be processed in the workflow simultaneously.

Photoexcitation processes in atoms

2021
hence, there is a need to independently determine the MEE signal, the atomic absorption background (AAB) for the analyzed element, and remove it prior to analysis. In view of the scarcity of elements which can practically be prepared in a free-atom gas state, several approaches to approximate the AAB have been developed: analysis of disordered ...

ATOMICITY AND CONCURRENCY CONTROL IN PROCESS CALCULI

Fundamenta Informaticae, 1997
A process calculus where atomic actions cooperate via explicit synchronization policies is presented. Bisimulation semantics for the calculus is provided with a sound and complete axiomatization. The problem of modeling concurrency control strategies is also addressed.

Analyses of atomization processes

Fuel, 1982
Abstract Atomized fluid fuels can be mixtures of combustible components (solid, liquid, gas). Disintegration of any fluid fuel occurs due to some phenomena such as turbulence, aerodynamic interaction, microexplosion. There is an equilibrium droplet diameter for each phenomenon.

Muonic atom — atom collision processes

1991
Elastic and inelastic processes of interaction of mesohydrogen in mixture of hydrogen isotopes with light nuclei are considered. The role of the electron screening in the elastic scattering is shown to be very important. Isotopic exchange reactions as well as muon transfer to light nuclei are considered.

Atomic Scattering Processes

Reviews of Modern Physics, 1961
Atomic reaction measurements and calculations are surveyed. Electron elastic scattering by H atoms, slow heavy-particle reactions, fast reactions, excitation transfer, and threshold behavior are discussed. Fairly suc cessful calculations exist for most processes; most data include some deviations from theory.
