Stabilised explicit Adams-type methods

Журнал Белорусского государственного университета: Математика, информатика, 2021
In this work we present explicit Adams-type multi-step methods with extended stability intervals, which are analogous to the stabilised Chebyshev Runge – Kutta methods.

Absolute stability of large-scale time-delay Lurie indirect control systems with unbounded coefficients

Advances in Difference Equations, 2017
We study the absolute stability of large-scale time-delay Lurie indirect control systems with unbounded coefficients. Based on Lyapunov-Krasovskii functional approach, we derive some novel absolute stability conditions for this class of Lurie systems ...

Absolute instability of double annular jets: local stability analysis

Archives of Mechanics, 2021
The paper presents the local linear stability analysis of the double annular jets. The calculations show that the first absolutely unstable helical mode can be generated in the non-swirling annular jets by the back-flow in the central recirculation zone ...

Absolute rate theories of epigenetic stability [PDF]

Proceedings of the National Academy of Sciences, 2005
Spontaneous switching events in most characterized genetic switches are rare, resulting in extremely stable epigenetic properties. We show how simple arguments lead to theories of the rate of such events much like the absolute rate theory of chemical reactions corrected by a transmission factor.

Inherent Stability of Multibody Systems with Variable-Stiffness Springs via Absolute Stability Theory

Complexity, 2021
In this paper, the inherent stability problem for multibody systems with variable-stiffness springs (VSSs) is studied. Since multibody systems with VSSs may consume energy during the variation of stiffness, the inherent stability is not always ensured ...
