Each individual Ca2+ spark is characterized by a set of spatio-temporal properties: the spatial half-width (full-width at half-maximum, FWHM), the rise time, the temporal “half-duration” (full-duration at half-maximum), and the peak amplitude. The decay time constant provides a temporal ...

But if we assume that log(.36) is close enough to -1, then we have a simple estimate for the time constant as simply: ThemeCopy tc = t0 - t_36 But that ONLY applies to the very simple case of an absolutely pure exponential decay. What you are trying to do completely invalidates ...
time domainThe time decay constant or "tau" of airborne electromagnetic (AEM) systems is commonly used to indicate the presence and relative conductivity or conductance of conductors in the survey area. In fact, it is not a constant because it depends on the system, the survey design and the...
Exponential decay of charge on a polymer surface with a time constant τ (Cross, 1987). It has been shown that charge decay from surfaces of textile materials is characterized by relatively fast initial decay, followed by slow final decay (Sessler, 1987). 17.5.2 Effect of moisture Water ...
The decay time constant increased as the square root of the inspection duration for values be- tween 1 min and 15 min of inspection. The ratings suggested that the MAEs consisted of three phases: an initial maximum-strength phase, a decay phase, and a tail. The duration of all three ...
