SR definition

language
Synchronizing Resources.
A language for concurrent programming.
"Resources" encapsulate processes and variables they share. Each Resource can be separately compiled. "Operations" provide the primary mechanism for process interaction.
SR provides a novel integration of the mechanisms for invoking and servicing operations. Consequently, it supports local and remote procedure call, rendezvous, message passing, dynamic process creation, multicast, semaphores and shared memory.

sr

unit of solid-angle measure in the International System of Units (SI), defined as the solid angle of a sphere subtended by a portion of the surface whose area is equal to the square of the sphere's radius. Since the complete surface area of a sphere is 4pi times the square of its radius, the total solid angle about a point is equal to 4pi steradians. Derived from the Greek for solid and the English word radian, a steradian is, in effect, a solid radian; the radian is an SI unit of plane-angle measurement defined as the angle of a circle subtended by an arc equal in length to the circle's radius
