Fractional Stability of Trunk Acceleration Dynamics of Daily-Life Walking: Toward a Unified Concept of Gait Stability

open access: yesFrontiers in Physiology, 2017
Over the last decades, various measures have been introduced to assess stability during walking. All of these measures assume that gait stability may be equated with exponential stability, where dynamic stability is quantified by a Floquet multiplier or ...

Exponential stability for nonlinear filtering [PDF]

open access: yesAnnales de l'Institut Henri Poincare (B) Probability and Statistics, 1997
The authors study the asymptotic dependence of the optimal filter on the initial law of the signal, and the relation between this dependence and the corrupting noise intensity. This is relevant for numerical and practical computations of the approximations of the filter.

Semi-Global Exponential Stability of Augmented Primal-Dual Gradient Dynamics for Constrained Convex Optimization

open access: yes, 2020
Primal-dual gradient dynamics that find saddle points of a Lagrangian have been widely employed for handling constrained optimization problems. Building on existing methods, we extend the augmented primal-dual gradient dynamics (Aug-PDGD) to incorporate ...

Exponential stability of abstract evolution equations with time delay [PDF]

open access: yes, 2014
We consider abstract semilinear evolution equations with a time delay feedback. We show that, if the $C_0$-semigroup describing the linear part of the model is exponentially stable, then the whole system retains this good property when a suitable ...

A unified framework of rapid exponential stability and optimal feedback control for nonlinear systems

open access: yesAdvances in Mechanical Engineering, 2019
A novel framework of rapid exponential stability and optimal feedback control is investigated and analyzed for a class of nonlinear systems through a variant of continuous Lyapunov functions and Hamilton–Jacobi–Bellman equation.

On (non-)exponential decay in generalized thermoelasticity with two temperatures [PDF]

open access: yes, 2016
Konstanzer Schriften in Mathematik ; 355We study solutions for the one-dimensional problem of the Green-Lindsay and the Lord-Shulman theories with two temperatures. First, existence and uniqueness of weakly regular solutions are obtained.

Global exponential stabilization of freeway models [PDF]

open access: yesInternational Journal of Robust and Nonlinear Control, 2015
SummaryThis work is devoted to the construction of feedback laws, which guarantee the robust global exponential stability of the uncongested equilibrium point for general discrete‐time freeway models. The feedback construction is based on a control Lyapunov function approach and exploits certain important properties of freeway models.

Almost Sure Exponential Stability of Numerical Solutions for Stochastic Pantograph Differential Equations with Poisson Jumps

open access: yesMathematics, 2022
The stability analysis of the numerical solutions of stochastic models has gained great interest, but there is not much research about the stability of stochastic pantograph differential equations.

Investor demand in syndicated EFSF/ESM bond issuances [version 2; peer review: 1 approved, 2 approved with reservations]

open access: yesOpen Research Europe
The European Financial Stability Facility (EFSF) and the European Stability Mechanism (ESM) were set up at the peak of the European sovereign debt crisis to issue bonds and lend to countries under current funding stress.

The split step theta balanced numerical approximations of stochastic time varying Hopfield neural networks with distributed delays

open access: yesResults in Control and Optimization, 2023
In this paper, split step theta balanced Euler approximations for stochastic time-varying delay Hopfield neural networks (HNN) with distributed delays are examined for their exponential stability and strong convergence.
