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.

RIGHT SIDED RADII SHOWS THE ABOVE MENTIONED RESULTS:
From Figure 23, we can see that excess loss is increasing as the coupler bending radii pair is increasing.
In other atoms the similar phenomenon is expected, because their atomic radii are greater than the Bohr one and therefore still greater than the finite elliptic ones:

The number of fillet radii in one pattern should be the minimum possible, preferably only one.
One of such revolutionary carpool applications is "Radii."
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.
