Simulation of the different mass-spring attractors. The damped exponential decay of the dotted equals \( \cos \left( {2\pi t} \right){ \exp }\left( { - t} \right) \), and for the solid line \( \cos \left( {8\pi t} \right){ \exp }\left( { - t} \right) \). Log lines indicate an embedded invariant property in terms of the relation between systems’ attractor (solid blue line) and damping potential (dotted red line). V volts, au arbitrary unit. Plot of the inset denotes an undamped case
