Figure 2From: Fractional Langevin model of gait variabilityEmpirical mass exponent and singularity spectrum: (a) The mass exponent is determined using the partition function from (28) and given by the dots for a typical data set. The solid curve is the quadradic least-squares fit of (29) to the calculated points. (b) The singularity spectrum is determined from the mass exponent using (9).Back to article page
