On Delay-independent Stability of a class of Nonlinear Positive Time-delay Systems [PDF]

open access: yesarXiv, 2013
We present a condition for delay-independent stability of a class of nonlinear positive systems. This result applies to systems that are not necessarily monotone and extends recent work on cooperative nonlinear systems.

Balancing for unstable nonlinear systems [PDF]

open access: yes, 1993
A previously obtained method of balancing for stable nonlinear systems is extended to unstable nonlinear systems. The similarity invariants obtained by the concept of LQG balancing for an unstable linear system can also be obtained by considering a past ...

Non-Mechanical Beam Steering with Polarization Gratings: A Review

open access: yesCrystals, 2021
Polarization gratings (PGs) enable a novel architecture for dynamic non-mechanical steering of light over large angles and with large clear apertures. This beam steering approach has many applications in active sensing and optical communications. In this

Higher order solitary solutions to the meta-model of diffusively coupled Lotka–Volterra systems

open access: yesAdvances in Difference Equations, 2021
A meta-model of diffusively coupled Lotka–Volterra systems used to model various biomedical phenomena is considered in this paper. Necessary and sufficient conditions for the existence of nth order solitary solutions are derived via a modified inverse ...
