The use of wavelets for noise detection in the images taken by the analog and digital photogrammetric cameras... As the second noise indicator the analysis of changing of relative variance during decomposition was researched....
Influence of statistical fluctuations on $k/\pi$ ratios in relativistic heavy ion collisions... It is shown that the distributions of theratio in these cases are Gaussian, and the mean and relative variance are givenanalytically.Comment:...
Weighting functions and data truncation in the fitting of multi-exponential functions (short communication)... The variation corresponded to either constant or relative variance for the data error....
Effective prestressing force testing method of external prestressed bridge based on frequency method... The analysis results show that the fundamental frequency of the prestressed tendons under fixed boundary condition is higher than that under hinged-support support boundary condition, and the relative variance decreases with the increase of tensioning force....
