Fractional stochastic vibration system under recycling noise
Published 2023-08-01“…Second, the Itô differential equations and One-dimensional Markov process are obtained according to the stochastic averaging method, using Oseledec multiplicative ergodic theorem and maximal Lyapunov exponent to judge local stability, and judging global stability is done by using the singularity theory. Lastly, the stochastic D-bifurcation behavior of the model is analyzed by using the Lyapunov exponent of the dynamical system invariant measure, and the stationary probability density function of the system is solved according to the FPK equation. …”

Bifurcation Analysis of a Micro-Machined Gyroscope with Nonlinear Stiffness and Electrostatic Forces
Published 2021-01-01“…Transition sets on the driving/detecting voltage plane that divide the parameter plane into 12 persistent regions and the corresponding bifurcation diagrams are obtained via the singularity theory. The results show that multiple solutions of the resonance curves appear with a large driving voltage and a small detecting voltage, which may lead to an uncertain output of the gyroscope. …”

Pierre Bayle and his reception in early eighteenth-century England: toleration in the Pensées Diverses and the Commentaire Philosophique
Published 2023“…Scholars usually speak of Bayle’s conception of toleration as if it were a singular theory. This thesis, however, contends that Bayle’s two most famous treatises on toleration, his Pensées diverses (1682) and his Commentaire philosophique (1686), introduced two notably different justifications for religious toleration. …”
