Nonlinear stability of laboratory quasi-Keplerian flows. [PDF]

Physical review. E, Statistical, nonlinear, and soft matter physics, 2014
Experiments in a modified Taylor-Couette device, spanning Reynolds numbers of 10(5) to greater than 10(6), reveal the nonlinear stability of astrophysically relevant flows.

Conformal-type energy estimates on hyperboloids and the wave-Klein-Gordon model of self-gravitating massive fields

Communications in Analysis and Mechanics, 2023
In this article we revisit the global existence result of the wave-Klein-Gordon model of the system of the self-gravitating massive field. Our new observation is that, by applying the conformal energy estimates on hyperboloids, we obtain mildly ...

Nonlinear Stability of the Current‐Vortex Sheet to the Incompressible MHD Equations [PDF]

, 2015
In this paper, we solve a long‐standing open problem: nonlinear stability of the current‐vortex sheet in the ideal incompressible magnetohydrodynamics under the Syrovatskij stability condition.

On sharp vorticity gradients in elongating baroclinic eddies and their stabilization with a solid‐body rotation

Geophysical Research Letters, 2016
Wide compensated vortices are not able to remain circular in idealized two‐layer models unless the ocean depth is assumed to be unrealistically large. Small perturbations on both cyclonic and anticyclonic eddies grow slower if a middle layer with uniform

Nonlinear Dynamic Stability of Cylindrical Reticulated Shells with Initial Damage

Buildings, 2023
As large-span structures, reticulated shells are widely used in large-scale public building and act as emergency shelters in the event of sudden disasters.

Stability Analysis of Parameter Varying Genetic Toggle Switches Using Koopman Operators

Mathematics, 2021
The genetic toggle switch is a well known model in synthetic biology that represents the dynamic interactions between two genes that repress each other.

Thermal Convection in a Rotating Anisotropic Fluid Saturated Darcy Porous Medium

Fluids, 2017
The stability of the thermal convection in a fluid-saturated rotating anisotropic porous material is investigated. We take into account the rotation of a layer of saturated porous medium about an axis orthogonal to the planes bounding the layer.

Revisiting the Complexity of Stability of Continuous and Hybrid Systems [PDF]

, 2014
We develop a framework to give upper bounds on the "practical" computational complexity of stability problems for a wide range of nonlinear continuous and hybrid systems.

Nonlinear stability of shear deformable eccentrically stiffened functionally graded plates on elastic foundations with temperature-dependent properties

Science and Engineering of Composite Materials, 2017
This article investigates the nonlinear stability of eccentrically stiffened moderately thick plates made of functionally graded materials (FGM) subjected to in-plane compressive, thermo-mechanical loads.

Stability and Analytic Solutions of an Optimal Control Problem on the Schrödinger Lie Group

Open Physics, 2016
The nonlinear stability and the existence of the periodic solutions for an optimal control problem on the Schrödinger Lie group are discussed. The analytic solutions via optimal homotopy asymptotic method of the dynamics and numerical simulations are ...
