In nature, as in everyday life, we are surrounded by resonance—the phenomenon that describes how each object has a frequency that it prefers to vibrate at. The note of a guitar string and the sound of ...

Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...

As a musician and sacred sound and light artist, Blanche has spent decades working with tone, harmonic entrainment, and the physiological effects of sound. His practice spans tuning forks applied ...

Physicists at Boston University have achieved what amounts to a long-sought benchmark in quantum measurement: detecting the spontaneous magnetic fluctuations of nuclear spins in a macroscopic sample ...

Low-frequency resonance is a bigger problem than high-frequency resonance in general industrial machines. This little-recognized distinction is crucial in determining the best way to correct it.

Harmonic distortion is not a problem unless it becomes a problem. Harmonics are a breakdown of a distorted waveform into its separate frequencies, which are integer multiples of the fundamental ...

Download this article in PDF format. Jacques and Pierre Curie, French physics, discovered the piezoelectric effect in 1880. When some solid material is mechanically compressed or stressed, the ...

Mechanical resonance is a pervasive problem in servosystems. Most resonance problems are caused by compliance of powertransmission components. Standard servocontrol laws are structured for rigidly ...
