Computer analysis of asymmetric peaks in gas chromatography
… peak symmetry, position and dispersion by central statistical moments. Benzene samples were chromatographed on squalane for columns of 3, 6 and 12 foot lengths and 1/8", 1/ 4" and 1/2" diameters as a function of sample size. Peak symmetry was monitored by measuring skew, γ₁ , and "excess," …

A stand level multi-species growth model for Appalachian hardwoods
… recovery method used employed the first two non-central moments of dbh (arithmetic mean dbh and quadratic mean dbh squared) to generate Weibull parameters. Future diameter distributions were generated for the whole stand and every species group but one; the diameter distribution of the remaining …

Compatible whole-stand and diameter distribution models for loblolly pine plantations
… The first used equations for the non-central moments of dbh. For the beta pdf, equations for the predicted first moment (average dbh) and second moment (basal area per acre/(0.005454 N)) were used to compute the analytic solution for parameter α and β. The endpoints of the pdf were …

Memory As First Breath: Critiquing and Disrupting the Lingering Politics of Memory of the Francoist Regime Through an Artistic Practice Involving a Personal Archive of Photographs
… (1975) and Law of Amnesty (1977) as the central moments of memory construction of the Francoist past during the Transition. This research examines the relationship between these events and the lingering discourses and affects of previous mnemonic narratives, especially those regarding …

Search for clustering of strange quarks in relativistic heavy ion collisions at the LHC
… clustering signature. We measured the higher moments of these distributions and compared them with the baselines, which have no clustering. These baselines are achieved either through simple statistical considerations of Poissonian particle production, leading to Gaussian signatures, or …

Some properties of the sample coefficient of variation
… values of the S.C.V. is discussed and the moments of the S.C.V. are shown not to exist. The above mentioned frequency function is then factored into a form suitable for computer calculations and an exact table of percentage points is derived and given in the Appendix. All moments of the …

A methodology based on local resolution of turbulent structures for effective modeling of unsteady flows
… data is achieved for the first and second central moments of the velocity components. These results illustrate the potential of the STRUCT approach to provide accurate LES-like predictions with a computational cost only about 10% higher than that of URANS while orders of magnitude lower …
