Equivalent kernels $h_{composed}(t;\mu )={*}_{k=1}^K{h}_{exp}(t;{\mu }_k)$ with temporal variance τ = 1 corresponding to the composition of K = 4 or K = 7 truncated exponential kernels with different time constants defined from a self-similar distribution of the temporal scale levels according to Equations (38), (39) and (40) and corresponding to a uniform distribution in terms of effective temporal scale τ_eff = log τ for c = 2^3/4 and with their first- and second-order derivatives.
