Heat-loss effects on the chaotic behavior of cellular premixed flames generated by intrinsic instability

open access: yesJournal of Thermal Science and Technology, 2007
Heat-loss effects on the chaotic behavior of cellular premixed flames generated by intrinsic instability were studied by two-dimensional unsteady calculations of reactive flows based on the compressible Navier-Stokes equation.

Asymptotic behavior of the forecast–assimilation process with unstable dynamics

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2022
Extensive numerical evidence shows that the assimilation of observations has a stabilizing effect on unstable dynamics, in numerical weather prediction, and elsewhere. In this paper, we apply mathematically rigorous methods to show why this is so.

Aggressive Behavior and Unstable Mental States in Car Drivers

open access: yesВестник Кемеровского государственного университета, 2019
The present paper focuses on the connection between aggressive behavior and unstable mental states in car drivers. The hypothesis was that aggressive behavior of drivers is caused by an unstable mental state.

Dynamic Anomalies of Fluids with Isotropic Doubled-Ranged Potential [PDF]

open access: yes, 2003
Using molecular dynamics simulations we investigate the ability of an analytical three-dimensional double well in reproducing static and dynamic anomalies found experimentally in liquid water.

The Unstable Behavior of Low and High-Speed Compressors [PDF]

open access: yesJournal of Turbomachinery, 1993
By far the greater part of our understanding about stall and surge in axial compressors comes from work on low-speed laboratory machines. As a general rule, these machines do not model the compressibility effects present in high-speed compressors and therefore doubt has always existed about the application of low-speed results to high-speed machines ...

Asymptotic inference for nearly unstable AR(p) processes [PDF]

open access: yes, 1999
In this paper nearly unstable AR( p) processes (in other words, models with characteristic roots near the unit circle) are studied. Our main aim is to describe the asymptotic behavior of the least-squares estimators of the coefficients.

Buoyant Unstable Behavior of Initially Spherical Lean Hydrogen-Air Premixed Flames

open access: yesEnergies, 2014
Buoyant unstable behavior in initially spherical lean hydrogen-air premixed flames within a center-ignited combustion vessel have been studied experimentally under a wide range of pressures (including reduced, normal, and elevated pressures).

Late Time Behavior of Unstable Particles

open access: yesJournal of Nuclear and Particle Physics, 2012
Possible consequences of non-exponential behavior of the survival amplitude of an unstable particle at very late times are considered. We describe a new quantum phenomenon: Analyzing the transition time region between exponential and post-exponential form of the survival amplitude we find that the instantaneous energy of the considered unstable state ...
