"Sailors were reminded of the planet's
roundness every time they climbed a mast to see further over the horizon or looked to the stars to determine their position.
However, measurements of
roundness seem to be insufficient way to evaluate form deviations of spherical elements.
P-values (0.000 and 0.042) underlined in Table 3 show that the main effects "Material" is significant for G-ratio and surface roughness which, unlike feed rate and material, are not significant for
roundness error.
For a quantitative analysis, the mean
roundness parameter is evaluated for each frame as the ratio between the minor ([A.sub.m]) and the major axis ([A.sub.M]) averaged over 20 microwells within a single field-of view of the microscope.
In this tempting Espresso, Livanto's balance and
roundness is complemented with the rich aromas of pastry, baked apples and a hint of cinnamon.
It is concluded that the measurements of root
roundness (R) and flattening (F) are consistent with microscopic observations and can be used to quantify root deformation under soil compaction.
From the quantities described above we can calculate the sphericity and
roundness, which have been defined as
Honing is the same process used to make diesel fuel injectors with bore
roundness and straightness controlled to fractions of a micron (<0.000040"), with surface finish Ra [less than or equal to]0.15 [micro]m (6 [micro]in).
CD34-stained sections were evaluated for MVD, and vascular architecture parameters including vessel area, diameter, perimeter, and
roundness were analyzed by using an image analyzer system (WinROOF, Mitani Corporation, Japan); WinROOF is an integrated software system for image processing, measurement, and data processing to support all image analysis-related operations [17, 18].
