We present a method for estimating the seismic intensity in terms of MMI or MSK scale using Fourier amplitude spectra of ground acceleration. The method implies that severity of earthquake ground motion is determined by spectral amplitudes in relatively narrow frequency band: so-called "representative...

Amplitude and Intensity Formulas in Physics Lesson Summary FAQs Activities How is intensity measured in physics? In physics, intensity is a measure of time-averaged power over area. The most common units for intensity are Watts per meter squared or Watts per centimeter squared. What is the co...

In the time-domain, the single point detection system is called time-correlated single-photon counting (TCSPC). The principle of the TSCPC system is shown in Figure 6. For each excitation pulse a trigger signal is sent to a time-to-amplitude converter (TAC) within which a capacitor starts...
A study of pure-tone intensity discrimination is presented in which amplitude changes are detected in 1000 Hz tone bursts 15鈥 20 msec in duration. The masking function (log detectable increment vs log background intensity) is found to ha... WJ Mcgill,JP Goldberg - 《Perception & Psychophysics...
