Beyond the Linear Damping Model for Mechanical Harmonic Oscillators
Randall D. Peters
The steady state motion of a folded pendulum has been studied using frequencies of drive that are mainly below the natural (resonance) frequency of the instrument. Although the fre…
Spreadsheet Filtering by FFT Gaussian-based Convolution
Randall D. Peters
Filtering of digital signals is accomplished on an Excel spreadsheet using fast Fourier transform (FFT) convolution in which the kernel is either a Gaussian or a cosine modulated G…
Postulated Mesoscale Quantum of Internal Friction Hysteresis
Randall D. Peters
Evidence is provided, from yet another experiment, for the existence of a mesoscale quantum of internal friction hysteresis, having the value of the electron rest energy divided by…
Folded Pendulum Measurements of Earth's Free Oscillations
Randall D. Peters
The nearly-incessant free oscillations of the Earth (not the larger, long-lived normal modes seen following intense quakes) were first observed by accident in the record of a tilt-…
