The calculation method of the Arithmetic Mean Deviation (Ra) is presented for rotational turning. necessary equations Ra are given beginning from equation cut surface theoretical profile, and we determine values in studied range technological parameters. Cutting experiments with these data were performed roughness machined surfaces measured. Then carried out a comparative analysis measured calc...

A central limit theorem and a moderate deviations principle for the ratio of geometric p-generalized arithmetic mean are shown. Also Berry–Esseen-type upper bound on rate convergence in is proved. This has implications probabilistic version question whether inequality between can be reversed or improved up to multiplicative constants. The involved random vectors we study belong class distributi...

The amplitude distribution in a SAR image can present a heavy tail. Indeed, very high–valued outliers can be observed. In this paper, we propose the usage of the Harmonic, Geometric and Arithmetic temporal means for amplitude statistical studies along time. In general, the arithmetic mean is used to compute the mean amplitude of time series. In this study, we will show that comparing the behavi...
