We have learned that an effective way to passively control vibration is through the usage of a “vibration absorber”. A typical vibration absorber is a single-DOF spring/mass/dashpot system that is ...

Consider an undamped single degree-of-freedom system experiencing harmonic excitation whose equation of motion (EOM) is given by: Here omega n is known as the natural frequency of response. The ...

Over last few decades, study of topological phases of matter in solid-state electron systems has been extended to other research field, including synthetic dimensions, and motivates extensive research ...
