A 3D STOCHASTIC MODEL FOR GEOMETRICAL CHARACTERIZATION OF PARTICLES IN TWO-PHASE FLOW APPLICATIONS
Image Analysis and Stereology, 2018 In this paper a new approach to geometrically model and characterize 2D silhouette images of two-phase flows is proposed. The method consists of a 3D modeling of the particles population based on some morphological and interaction assumptions.

A Process Calculus of Atomic Commit
Electronic Notes in Theoretical Computer Science, 2004 AbstractThis article points out a strong connection between process calculi and atomic commit. Process calculus rendezvous is an abstract semantics for atomic commitment. An implementation of process-calculus rendezvous is an atomic commit protocol. Thus, the traditional correctness properties for atomic commit are entailed by a bisimulation proof of a

Mixing Study in an Unbaffled Stirred Precipitator Using LES Modelling
International Journal of Chemical Engineering, 2012 This paper describes the CFD modelling of a reactor operating in the nuclear industry using LES approach. The reactor consists of an unbaffled stirred tank reactor in which plutonium precipitation reactions are carried out.

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.
