Influence of Hysteresis on the Vibration Control of a Smart Beam with a Piezoelectric Actuator by the Bouc–Wen Model

open access: yesShock and Vibration, 2020
The hysteresis property in a smart structure has attracted much attention from researchers for several decades. Hysteresis not only affects the response precision of the smart structure but also threatens the stability of the system.

Is There Daily Growth Hysteresis versus Vapor Pressure Deficit in Cherry Fruit?

open access: yesHorticulturae, 2021
The growth of cherry fruit is generally described using a double sigmoid model, divided into four growth stages. Abiotic factors are considered to be significant components in modifying fruit growth, and among these, the vapor pressure deficit (VPD) is ...

Bistable fully developed mixed convection flow with viscous dissipation in a vertical channel [PDF]

open access: yesRoyal Society Open Science, 2018
It is shown that unstable dual solutions in fully developed mixed convection flow in a vertical channel disappear in the presence of relatively strong thermal radiation. In this case, we have a unique stable flow at each pressure gradient.
