Steady energy transfer dependence granular temperature on single bouncing granular particle

Simulation of a system consisted of free particle bouncing on a vertically vibrated based is performed. Two different states, which are steady and unsteady energy transfer state are found. The vibrating based is hold at constant vibration frequency $f = 0.1$ as the vibration amplitude $A$ varied. Sinusoidal form is used. Granular temperature $T_g$ as function of based velocity and coefficient of restitution is used but shown no role in determining energy transfer state of the system. Peak of free particle trajectory $x_m$ around value 20 seperate region of the two states.
