MHD Stability Calculations of High-Beta Quasi-Axisymmetric Stellarators

open access: yes, 1999
The MHD stability of quasi-axisymmetric compact stellarators is investigated. It is shown that bootstrap current driven external kink modes can be stabilized by a combination of edge magnetic shear and appropriate 3D plasma boundary shaping while ...

Generalized approximation Hyers-Ulam-Rassias type stability of generalized homomorphisms in quasi-Banach algebras

open access: yes, 2022
In this paper, we study to solve the Hyers-Ulam-Rassias stability of generalized homomorphisms in quasi-Banach algebras, associated with Jensen-type additive functional equation with 2k-variables.

Stability and quasi-periodicity of many-body localized dynamics

open access: yesNew Journal of Physics
The connection between entanglement dynamics and non-equilibrium statistics in isolated many-body quantum systems has been established both theoretically and experimentally.

Enhanced performance and stability of quasi two-dimensional perovskite solar cells by conductive phosphine oxide

open access: yesResults in Physics
Recently, quasi two-dimensional (quasi-2D) perovskite solar cells (PSCs) have been paid more attentions due to their good stability. While the efficiency of 2D PSCs is lower than that of 3D ones due to their poor charge transport property.

Pullback attractors via quasi-stability for non-autonomous lattice dynamical systems

open access: yesDiscrete and Continuous Dynamical Systems - B, 2022
<p style='text-indent:20px;'>In this paper we study long-time behavior of first-order non-autono-mous lattice dynamical systems in square summable space of double-sided sequences using the cooperation between the discretized diffusion operator and the discretized reaction term.

The critical merger distance between two co-rotating quasi-geostrophic vortices [PDF]

open access: yes, 2005
This paper examines the critical merger or strong interaction distance between two equal-potential-vorticity quasi-geostrophic vortices. The interaction between the two vortices depends on five parameters: their volume ratio, their height-to-width aspect

Design of high-performance millimeter wave and sub-millimeter wave quasi-optical isolators and circulators [PDF]

open access: yes, 2007
Faraday rotators using permanently magnetized ferrite materials are used to make quasi-optical isolators and circulators at millimeter wave and sub-millimeter wave frequencies that have far higher performance than their waveguide equivalents.

Quasi-contractivity, Stability and convergence of WCT operators [PDF]

open access: yes
In this paper we characterize quasi-contraction, stable and convergent weighted conditional type (WCT) operators on $L^p(\mu)$. Indeed we provide equivalent conditions for quasi-contraction WCT operators.

Design controler of the quasi-time optimization approach for stabilizing and trajectory tracking of inverted pendulum

open access: yesMATEC Web of Conferences, 2018
This article describes the method of stabilizing and tracking the trajectory of the inverted pendulum with the quasi-time optimization approach. The controller proposed in this paper is not only to stabilize the inverted pendulum in a vertical position ...

Including Social Nash Equilibria in Abstract Economies [PDF]

open access: yes
We consider quasi-variational problems (variational problems having constraint sets depending on their own solutions) which appear in concrete economic models such as social and economic networks, financial derivative models, transportation network ...
