In view of the facts in the infection and propagation of COVID-19, a stochastic reaction–diffusion epidemic model is presented to analyse and control this infectious diseases. Stationary distribution and Turing instability of this model are discussed for deriving the sufficient criteria for the persistence and extinction of disease. Furthermore, the amplitude equations are derived by using Taylor series expansion and weakly nonlinear analysis, and selection of Turing patterns for this model can ...

To avoid structural failure, the issue of the dynamic reliability of a wrinkled-film-substrate structure has become one of the most key problems for the design of the film-substrate-type flexible electronics. In this paper, an improved theoretical model of such a structure with finite deformation is established, which takes the shear stress at the interface between the film and substrate into account. Post-buckling mode would take place when that structure is subjected to further repeated stretc...

A nonlinear analysis is performed on a two-degree-of-freedom wing-based system. Structural nonlinearities are introduced in the pitch degree of freedom when considering two different forms of the aerodynamic loads. Comparisons between quasi-steady and unsteady aerodynamic representations are investigated and discussed including stall effects. The nonlinear aeroelastic response is carried out in the presence of quadratic and cubic nonlinearities in the pitch degree of freedom. The effects of the ...

The prediction and control of excessive vibration are one of the most important concerns in the design and development of geared systems. For any gear set, parametric resonance is the main source of instability, resulting in the separation of gears in mesh and chaotic behavior. In many works, gears are modeled with rigid mountings, and various analytical and numerical approaches have been used to investigate the dynamic characteristics of the system in different regimes: permanent contact (no im...

By adopting the absolute nodal coordinate formulation, a novel and general nonlinear theoretical model, which can be applied to solve the dynamics of combined straight-curved fluid-conveying pipes with arbitrary initially configurations and any boundary conditions, is developed in the current study. Based on this established model, the nonlinear behaviors of a cantilevered L-shaped pipe conveying fluid with and without base excitations are systematically investigated. Before starting the researc...

An integrated strategy is proposed for asteroid orbiting, consisting of stationkeeping, autonomous navigation, and real-time geodetical recovery. It is designed to maintain the spacecraft on its nominal trajectory under some uncertainties from the spacecraft and the asteroid. Furthermore, it performs adaptive estimations on the mass and thruster of spacecraft, as well as the spherical harmonic coefficients and spin rate of the gravity field of asteroid. These estimations are then substituted int...
