However, in the studies carried out afterwards, it has been shown that the water equivalent diameter ([D.sub.w]) acts as the most appropriate size indicator since it discriminates between different body regions with similar geometric dimensions but different attenuation properties (thorax, abdomen, pelvis) (9, 10).
equivalent diameter, the former is the latest high performance macro-synthetic fiber developed from the Fibermesh-pioneered HPP technology.
The terminal velocity of the bubbles as function of the equivalent diameter using the drag force coefficients of (7) and (12) is compared in Figure 5.
Nine morphology features were calculated: six from the size of the nucleus (area, perimeter, equivalent diameter, convex area, length of the major axis, and length of the minor axis) and three from the shape of the nucleus (eccentricity, solidity, and extent).
Two main factors to consider with the relief hole is the diameter or equivalent diameter and the length of the relief hole.
I then calculate the area of that gate and convert it to the equivalent diameter. For the part above: 0.060 x 0.120 in.
When the bed particles are not spherical they are represented as an equivalent sphere of the same volume which can be characterized by the equivalent diameter or by the sphericity (a particles deviation from a perfect sphere), When the particles are spherical the equivalent diameter simply reduces to the particle diameter.
In addition, the relationship between the heating time and oil shale particle equivalent diameter was established.
(5) Equivalent diameter: the diameter of spherical particle with the same volume of nonspherical particle
Since there is a large difference between the compressive modulus of a steel bar and an FRP bar, the equivalent flexural rigidity of an SFCB is defined as [E.sub.s][I.sub.sf_Is.sup.e] = [E.sub.s][I.sub.s] + [E.sub.f][I.sub.f] (Figure 8), and the corresponding equivalent diameter ([d.sub.sf_ls.sup.e]) and equivalent compressive strength ([f.sub.sf_Is.sup.e]) of SFCB can be calculated using (6) and (7), respectively:
Different formulations exist to compute the equivalent diameter as shown by Lamarche [18] or by Chiasson [9].
