Inclined convection in a porous Brinkman layer: linear instability and nonlinear stability. [PDF]
Proc Math Phys Eng Sci, 2019 In this article, we deal with thermal convection in an inclined porous layer modelled by the Brinkman Law. Inertial effects are taken into account, and the physically significant rigid boundary conditions are imposed.

Nonlinear stability analysis of whirl flutter in a rotor-nacelle system. [PDF]
Nonlinear Dyn, 2018 Whirl flutter is an aeroelastic instability that affects propellers/rotors and the surrounding airframe structure on which they are mounted. Whirl flutter analysis gets progressively more complicated with the addition of nonlinear effects.

Contraction Theory for Nonlinear Stability Analysis and Learning-based Control: A Tutorial Overview [PDF]
Annual Reviews in Control, 2021 Contraction theory is an analytical tool to study differential dynamics of a non-autonomous (i.e., time-varying) nonlinear system under a contraction metric defined with a uniformly positive definite matrix, the existence of which results in a necessary ...

Nonlinear stability analysis of transitional flows using quadratic constraints [PDF]
Physical Review Fluids, 2020 The dynamics of transitional flows are governed by an interplay between the non-normal linear dynamics and quadratic nonlinearity in the Navier-Stokes equations. In this work, we propose a framework for nonlinear stability analysis that exploits the fact
