## Distance

distance in depth between servicemen, guns, vehicles, and subunits or units (ships) when formed in ranks, on the march (cruise), or in combat formation and also between aircraft when flying in formation or in a combat formation.

## Distance

an important geometric concept whose meaning depends on the kind of entities for which it is defined. The distance between two points is the length of the line segment joining the points. The distance from a point to a line or a plane is the length of the perpendicular from this point to the line or plane. The distance between two parallel lines or planes is the length of a common perpendicular to the lines or planes. The distance between two nonintersecting nonparallel lines in space is equal to the distance between the parallel planes in which the lines lie—that is, the length of the line segment that joins the lines and is perpendicular to both.

(mathematics)
A nonnegative number associated with pairs of geometric objects.
The spatial separation of two points, measured by the length of a hypothetical line joining them.
For two parallel lines, two skew lines, or two parallel planes, the length of a line joining the two objects and perpendicular to both.
For a point and a line or plane, the length of the perpendicular from the point to the line or plane.

Jayaraman, who got off the tablets a month after joining FFD in 2014, vouches that the reversal can persist as long as patients keep the excess weight off, and the changes they make in their eating and exercise habits are maintained.
Additionally, it is noted that our FFD solver was parallelized in OpenCL to run on the GPU, largely consistent with Tian et al.

The same ROIs are used in the "affine" and "FFD" schemes.
3, HA consumes less 16.2%-76% cost than FFD for leasing VMs from public cloud.
Finally, Bland and Altman plots were created and bias statistics calculated, and 95% limits of agreement.[23] To investigate the concurrent validity of the FFD test, the relationship of the test outcome was examined with the concurrent digital dual inclinometry measures using Pearson correlation coefficients.
The test groups were treated with increasing doses of 0.1, 0.5, 2.5 and 12.5 g/kg of FFD, respectively.
FFD Financial expects that its stock will be delisted from Nasdaq about 21 June after which date its shares will likely trade on the over-the-counter markets.
