Stochastic finite-time \(H_\infty\) performance analysis of continuous-time systems with random abrupt changes

Abstract and Applied Analysis, 2013
Summary: The problem of \(H_\infty\) control performance analysis of continuous-time systems with random abrupt changes is concerned in this paper. By employing an augmented multiple mode-dependent Lyapunov-Krasovskii functional and using some integral inequalities, new sufficient conditions are obtained relating to finite-time bounded and an \(H_ ...

The Caputo Nonlocal Structural Derivative Ultraslow Diffusion Model of Language Change and the Microscopic Mechanism

Fractal and Fractional
Numerous studies have observed and analyzed the dynamics of language change from a diffusion perspective. As a complex and changeable system, the process of language change is characterized by a long memory that conforms to ultraslow diffusion.

A Randomized Pilot Study of Time-Restricted Eating Shows Minimal Microbiome Changes

Nutrients
Objective: TRE is an emerging approach in obesity treatment, yet there is limited data on how it influences gut microbiome composition in humans. Our objective was to characterize the gut microbiome of human participants before and after a TRE intervention.

Research of the Bifurcation Characteristic of Helical Gear System with Considering Random Perturbation of Mesh Stiffness

Jixie chuandong, 2019
In order to study the influence of the random perturbation of time-varying mesh stiffness on the dynamics of the helical gearing system, based on Newton's law, a stochastic dynamics model of a six-degree-of-freedom helical gear system is established and ...
