Lyapunov Spectrum of Nonautonomous Linear Young Differential Equations [PDF]

Journal of Dynamics and Differential Equations, 2019
Abstract We show that a linear Young differential equation generates a topological two-parameter flow, thus the notions of Lyapunov exponents and Lyapunov spectrum are well-defined. The spectrum can be computed using the discretized flow and is independent of the driving path for triangular systems which are regular in the sense of ...

Switchable Privacy Displays: Applications, Optical Measurements, and Evaluation With Focus on Automotive

Journal of the Society for Information Display, EarlyView.
Switchable‐privacy displays can be used to protect sensitive data in public spaces and to avoid driver distraction on codriver displays. The key optical parameters are the luminance in public and privacy modes, measured over the viewing angle, and the image quality for the intended observers.

Impulsive Control Strategy for a Nonautonomous Food-Chain System with Multiple Delays

Journal of Control Science and Engineering, 2016
A nonautonomous food-chain system with Holling II functional response is studied, in which multiple delays of digestion are also considered. By applying techniques in differential inequalities, comparison theorem in ordinary differential equations ...

Dynamic behaviors of a nonautonomous predator–prey system with Holling type II schemes and a prey refuge

Advances in Difference Equations, 2021
In this paper, we consider a nonautonomous predator–prey model with Holling type II schemes and a prey refuge. By applying the comparison theorem of differential equations and constructing a suitable Lyapunov function, sufficient conditions that ...

Nonuniform almost reducibility of nonautonomous linear differential equations [PDF]

Journal of Mathematical Analysis and Applications, 2020
We prove that a linear nonautonomous differential system with nonuniform hyperbolicity on the half line can be expressed as diagonal system with a perturbation which is small enough. Moreover we show that the diagonal terms are contained in the nonuniform exponential dichotomy spectrum.

Beyond Reality Avoidance: Unraveling the Paradox of Escapism Through Self‐Monitoring and Autonomy Mechanisms for Consumers' Life Satisfaction

Psychology &Marketing, EarlyView.
ABSTRACT This study introduces the Paradox of Escapism, exploring how the act of escaping reality can evolve from a short‐term avoidance strategy to a mechanism for self‐regulation and enhanced life satisfaction. Employing five rigorous, multimethod investigations, including qualitative interviews and sentiment analysis (Study 1), Structural Equation ...

Weighted Stepanov-Like Pseudoperiodicity and Applications

Abstract and Applied Analysis, 2014
By the weighted ergodic space, we propose a new class of functions called weighted Stepanov-like pseudoperiodic function and explore its properties. Furthermore, the existence and uniqueness of the weighted pseudoperiodic solution to fractional integro ...

Input–Output Finite‐Time Stability and Stabilization of Nonautonomous Nonlinear Quadratic Systems via State and Output Feedback

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper presents novel results regarding the input–output finite‐time stability (IO‐FTS) of nonlinear quadratic systems (NLQSs), a class of dynamical models particularly useful for the study of robotic systems, biochemical reaction networks, and other processes of interest to the applied sciences.
