radius

1. a straight line joining the centre of a circle or sphere to any point on the circumference or surface

2. the length of this line, usually denoted by the symbol r

3. the distance from the centre of a regular polygon to a vertex (long radius) or the perpendicular distance to a side (short radius)

4. Anatomy the outer and slightly shorter of the two bones of the human forearm, extending from the elbow to the wrist

5. a corresponding bone in other vertebrates

6. any of the veins of an insect's wing

7. a group of ray florets, occurring in such plants as the daisy

8. the lateral displacement of a cam or eccentric wheel

RADIUS

(Remote Authentication Dial-In User Service) An authentication, authorization and accounting (AAA) protocol developed by Livingston Enterprises (later acquired by Lucent). RADIUS uses a challenge/response method for authentication and has been widely used prior to Diameter. See Diameter, network access server and challenge/response.

These are the same only in the infinitely far field where space-time is asymptotically Minkowski, (that is, pseudo-Euclidean) where the radii coalesce to become identical because, in Euclidean space, the radius of curvature and the proper radius are identical.

Vacuum forming of industrial parts is usually done over a male tool, which controls the inside surface of the part and usually has large radii. Pressure forming, however, typically occurs in a female tool, which controls the outside or appearance surface of the part and can achieve tight radii down to 0.005 in.
