Quasi-stability of a plasma bicylinder
Technical Physics, 2003Observations seem to indicate that, in the plasmas of tokamaks and Z-pinches, short-lived closed current loops (filaments) can arise, each of which is composed of a pair of countercurrents flowing within the two halves of the cross section of the plasma cylinder in directions perpendicular to that of the main magnetic field.

Quasi-stability regions of nonlinear dynamical systems: theory
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1996The concept of a stability region (region of attraction) of nonlinear dynamical systems is widely accepted in many fields such as engineering and the sciences. When utilizing this concept, the Lyapunov function approach has been found to give rather conservative estimations of the stability regions of many nonlinear systems.

Quasi‐stability and upper semicontinuity for coupled parabolic equations with memory
Studies in Applied Mathematics, 2020AbstractThis current study deals with the long‐time dynamics of a nonlinear system of coupled parabolic equations with memory. The system describes the thermodiffusion phenomenon where the fluxes of mass diffusion and heat depend on the past history of the chemical potential and the temperature gradients, respectively, according to Gurtin‐Pipkin's law.

Quasi-Stability of Real Coded Finite Populations
2014This contribution analyzes dynamics of mean and variance of real chromosomes in consecutive populations of an Evolutionary Algorithm with selection and mutation. Quasi-stable state is characterized with an area in which population mean and variance will remain roughly unchanged for many generations. Size of the area can be indirectly estimated from the

Thermodynamic quasi-stability of super entropic BTZ black hole
International Journal of Modern Physics A, 2022We know that criteria for thermodynamic stability of a most general black hole appears in the form of a series of inequalities connecting second-order derivatives of the black hole mass with respect to its parameters. Quasi-stable black holes satisfy some of these stability criteria in a certain regime of parameter space, but they never satisfy all ...

Quasi-stability regions of nonlinear dynamical systems: optimal estimations
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1996In this paper, we develop an effective scheme to estimate stability regions by using an energy function that is a generalization of the Lyapunov functions. It is shown that the scheme can optimally estimate stability regions. A fairly comprehensive study for the structure of the constant energy surface lying inside the quasi-stability region is ...
