Riemann conventional

Transformation of data from the time to the frequency domain enables noise to be more easily eliminated. The FFT approach also has an advantage over digital smoothing techniques in that the latter introduces distortions in the smoothed signal (.31). Another example of a useful transform technique is the worlT of Soong and Maloy who employed the Riemann Liouville transform to discriminate the faradaic current form the capacitive and adsorptive currents in polarographic measurements (32). The use of this transform technique affords a sensitivity tliat compares favourably with conventional pulse or differential pulse... 

GRPo denotes the conventional Riemann Problem (RP) with two constant functions as initial condition.
