The higher the frequency, the sharper the image becomes, revealing structure, size, and shape that was previously less discernible.

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 ...

f = frequency = number of waves produced by a source per second, in hertz Hz. T = period = time it takes for one complete vibration or oscillation, in seconds s. A boat at sea bobs up and down as ...
