The study of bubble dynamics, especially the interaction of bubbles, has drawn considerable attention due to its various applications in engineering and science. Meanwhile, the study of the oscillation effect of a bubble on the emitted pressure wave of another bubble in an acoustic field which has less been investigated. This issue is investigated in the present study using the coupling of Kell...

Speculative evaluation can improve the performance of parallel graph reduction systems through increased parallelism. Although speculation is costly, much of the burden can be absorbed by processors which would otherwise be idle. Despite the overhead required for speculative task management, our prototype implementation achieves 70% eeciency for speculative graph reduction, with little impact o...

In this paper, we approached the concept of real estate bubble, analyzing risk its bursting could generate for Chilean financial market. Specifically, analyzed relationship between housing prices, economic activity index, and mortgage interest rates denominated in inflation-linked units from 1994 to 2020. The analysis was based on a second order Markov switching model with predetermined variabl...

purpose: to investigate the results of deep lamellar keratoplasty (dlk) by big bubble method with using shifting bubble sign in patients suffering from keratoconus or corneal opacity methods: in this prospective interventional clinical trial, 20 eyes of 18 patients (10 males and 8 females) who underwent dlk by big bubble method using shifting bubble sign were investigated. mean age of cases wer...

In present paper acombination of three-dimensional isothermal and two-dimensional non-isothermal Lattice Boltzmann Method have been used to simulate the motion of bubble and effect of wetting properties of the surface on bubble separation. By combining these models, three-dimensional model has been used in two-dimension for decreasing the computational cost. Firstly, it has been ensured that th...

Abstract Australian housing markets experienced widespread and, in some cases, extraordinary growth prices between 2020 and 2023. Using recently developed methodology that accounts for fundamental economic drivers, we assess the existence degree of speculative behaviour, as well timing exuberance downturns these markets. Our findings indicate behaviour was indeed present six eight capital citie...

In this paper, a CFD model of syngas flow in slurry bubble column was developed. The model is based on an Eulerian-Eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. Numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. Also, the ef...
