Energy storage system decay rate table
Activity is usually measured in disintegrations per second (dps) or disintegrations per minute (dpm). The activity of a sample is directly proportional to the number of atoms of the radioactive isotope in the sample: [A = kN label{21.4.4}] Here, the symbol k is the radioactive decay constant, which has units of inverse time (e.g., s −1, yr −1) and a …

Optimal energy decay rates for abstract second order evolution equations with non-autonomous damping
By an idea of asymptotic rate-sharpening (among others), we obtain the optimal decay rate of the energy of the non-autonomous evolution equation in terms of γ(t) and f. As a byproduct, we show the optimality of the energy decay rates obtained previously in the literature when f is a monotone operator.

2.4: Rates of Radioactive Decay
In any sample of a given radioactive substance, the number of atoms of the radioactive isotope must decrease with time as their nuclei decay to nuclei of a more stable isotope. Using (N) to represent the number of atoms of the radioactive isotope, we can define the rate of decay of the sample, which is also called its activity ((A)) as the decrease in the …
