They have irregular crimp (curvature), with the finer fibre generally showing lower growth rates and higher crimp. The fibre surface is rough due to the outer layer of overlapping cuticle cells. By far the most important dimension is the fibre diameter. Wool fibres exhibit a range of diameters...
Curvature bounded above CAT(K) Length estimate 1. Introduction We give in this paper basic properties of total curvature and a sharp upper estimate on the length of a curve in a CAT(K) space through its total curvature and chordlength. This estimate is of a type due to E. Schmidt. See...
The focal length is half the radius of curvature and is as f=R2, where f is the focal length, and R is the radius of curvature. Convex and Concave Mirrors Convex and concave mirrors are sections of a whole spherical mirror. A concave mirror has a reflecting surface on the inner part ...
of the retina.) The axial length of the eye at birth is approximately 17 mm and reaches approximately 24 mm in adulthood. It is typically longer than 24 mm in myopes and shorter than 24 mm in hyperopes. Each mm of change in axial length of the eye corresponds to approximately 2.5 DSee...

The length of a dead-end street or cul-de-sac shall not exceed 750 feet, as measured from the first point of curvature of the cul-de-sac loop to the right of way line of the intersecting roadway, unless a greater length is deemed desireable by the Planning Board, because of ...
Background The height of patients with idiopathic scoliosis (IS) is diminished due to the curvature of the spine. Several clinical parameters (BMI, vital capacity, others) are dependent on the patient's height [ 1 , 2 ]. We developed a formula to calculate the corrected length of the ...

The two ends are then pulled apart, which reduces the radius of curvature of the loop. Microscopy is typically used to measure the radius of curvature at the top of the loop. Fukuda et al. [99] later developed mechanics equations to calculate this radius of curvature based on the ...
