An alternative formula has been derived to enable aclose prediction of the radius of curvature of a thinbimetallic strip that at initial ambient temperature, isboth flat and straight, but at above ambienttemperature, forms into an arc of a circle. The formulaenables the evaluation of the radius...

Spheres. A great circle in a sphere Σ ⊂ R3 is a circle cut from Σ by a plane P through the center (Fig. 5.32). If a is a constant-speed parametrization of any circle, we know that its acceleration α″ points toward the center of the circle. In the case of a great circle ...
A quantitative way of defining curvature is to consider a circle on the surface of interest and make it small, with a geodesic radius of distance a. Now measure the circumference, C. If a and C are related by a factor of 2π, then the surface is flat. If the circumference is less ...

Curvature can be defined as the reciprocal of the radius of a circle that is tangent to the given curve at a point. Thus curvature will be large for a curve that is bent more and will be zero for a straight line. Mathematically, curvature may simply be defined as a second order derivat...
The average curvature of the arc of a circle is equal to the reciprocal of the circle’s radius and thus gives an intuitive characterization of the degree of curvature of a circle: the arc’s curvature increases with decreasing radius.
The main display routines for users are the evolution of curvatures at various vertices during the curvature flow, the evolution of transition rates of edges emanating from vertices, and the display of individual weighted graphs with vertices arranged in a circle. The relevant routines are the follo...
insteadof considering the familiar rate of change in direction of the tangent. Thelatter approach is easily visualized via the osculating circle, which, however,does not lend itself to generalization to higher dimensions, since surfaceshave no osculating spheres (at non-umbilical points, of course)...
1) error due to curvature of position circle 船位线曲率误差2) position line error 船位线误差1. But the direction of position line error is overlooked in the textbook, with the result that the formula of standard error of transferred position line and running fix is mistaken. 但是,由于都...
