When a valve, pump, heater, or some other device reaches the end of its scale, that device becomes the primary control element. If the process was not designed with the idea of having that device in such a role, you’re stuck. Webb9 jan. 2024 · In this paper, we study a Timoshenko system with local Kelvin–Voigt damping, which models the dynamics of a beam. We prove that the energy of the system decays exponentially or polynomially and the decay rate depends on properties of material coefficient function. bruised chest wearing heart monitor
