[3G01] Criticality Analysis of Inverse Power Law Random Media with Spectral Range Control
Keywords:spectral range, power spectrum, incomplete randomized Weierstrass function, criticality analysis, inverse power law
In the power spectrum measurement of natural and engineering phenomena, there are upper and lower limits in the frequency domain variables. Therefore, in this excerpt, we report that the randomized Weierstrass function for the modelling of inverse power law power spectrum has been extended so that the range of frequency domain variable can be set arbitrarily. This extension is born out of breaking the relationship with the convergence issue in the fractalness of Weierstrass function and thus named an incomplete randomized Weierstrass function (IRWF). As a demonstration of the engineering usefulness of IRWF, the uncertainty evaluation of neutron effective multiplication factor is shown for the fuel debris in a sufficiently water-moderated environment.
