proximity space
1Proximity space — In topology, a proximity space is an axiomatization of notions of nearness that hold set to set, as opposed to the better known point to set notions that characterize topological spaces.The concept was described by Frigyes Riesz in 1908 and… …
2Proximity-1 Space Link Protocol — is a short haul delivery protocol designed to establish a two way communications link between a lander and an orbiter, negotiate data rate and communications mode, and reliably deliver data during short orbiter to surface contacts. Developed by… …
3proximity — proximity, propinquity are often used almost interchangeably to denote nearness. Proximity, however, commonly implies simple and often temporary nearness in space; it may be used with reference to either persons or things found in the same… …
