Modification of Empirical Strong Ground Motion Attenuation Relations to Include the Amplitude and Duration Effects of Rupture Directivity

, 1997
Rupture directivity effects cause spatial variations in ground motion amplitude and duration around faults and cause differences between the strike-normal and strike-parallel components of horizontal ground motion amplitudes, which also have spatial ...

Large Amplitude Elastic Motions in Proteins from a Single-Parameter, Atomic Analysis.

Physical Review Letters, 1996
Normal mode analysis (NMA) is a leading method for studying long-time dynamics and elasticity of biomolecules. The method proceeds from complex semiempirical potentials characterizing the covalent and noncovalent interactions between atoms.

Effect of Memory for Amplitude on Amplitude Discrimination

The Journal of the Acoustical Society of America, 1959
A two alternative forced-choice experiment (2 AFC) in which the observer is asked to state which is the larger of two segments of tones presented sequentially in time, is analyzed as an experiment involving only amplitude memory. Frequency, phase, starting time, and duration information is provided each trial by the stimuli.

Offset‐amplitude variation and controlled‐amplitude processing

GEOPHYSICS, 1985
The partition of plane seismic waves at plane interfaces introduces changes in seismic amplitude which vary with angle of incidence. These amplitude variations are a function of the elastic parameters of rocks on either side of the interface. Controlled‐amplitude processing is designed to obtain the true amplitude information which is geologic in ...

Quantitative measurements of vibration amplitude using a contact-mode freestanding triboelectric nanogenerator.

ACS Nano, 2014
A vibration sensor is usually designed to measure the vibration frequency but disregard the vibration amplitude, which is rather challenging to be quantified due to the requirement of linear response.
