The D50 is the size in microns that splits the distribution with half above and half below this diameter. The Dv50 (or Dv0.5) is the median for a volume distribution, Dn50 is used for number distributions, and Ds50 is used for surface distributions. Since the primary result from laser diffraction is a volume distribution, the default D50 cited ...

A GUIDEBOOK TO PARTICLE SIZE ANALYSIS

Effect size is an essential component when evaluating the strength of a statistical claim, and it is the first item (magnitude) in the MAGIC criteria. The standard deviation of the effect size is of critical importance, since it indicates how much uncertainty is included in the measurement. A standard deviation that is too large will make the ...

Vertical variability in the raindrop size distribution (RSD) can disrupt the basic assumption of a constant rain profile that is customarily parameterized in radar-based quantitative precipitation estimation (QPE) techniques. This study investigates the utility of melting layer (ML) characteristics to help prescribe the RSD, in particular the mass-weighted mean diameter (Dm), of stratiform ...

Nov 01, 1988· If observed oil and gas field size distributions are obtained by random samplings, the fitted distributions should approximate that of the parent population of oil and gas fields. However, empirical evidence strongly suggests that larger fields tend to be discovered earlier in the discovery process than they would be by random sampling.

As explained above, the shape of the t-distribution is affected by sample size. As the sample size grows, the t-distribution gets closer and closer to a normal distribution. Theoretically, the t-distribution only becomes perfectly normal when the sample size reaches the population size.

The required particle-size distribution is shown to be quite broad, with approximately a power-law distribution, for all substances considered. The sizes for graphite are estimated to vary from about 0.005 to about 1 micron, and the observed uniformity of extinction over the sky is explained in terms of a rather uniform power-law exponent ...

The body size-species richness distribution is a pattern observed in the way taxa are distributed over large spatial scales. The number of species that exhibit small body size generally far exceed the number of species that are large-bodied. Macroecology has long sought to understand the mechanisms that underlie the patterns of biodiversity, such as the body size-species richness pattern.
