The volume of data from future NASA space missions will be phenomenal. Here, we examine the expected data flow from the Space Station Freedom and describe techniques that are being developed to transport and process that data. Networking in space, th

Analogues of ring theory results concerning the Jacobson radical of a regular ring are obtained for near-rings with a two-sided zero. The quasiradical and the radical-subgroup of a regular near-ring are shown to be {0}. Some sufficient conditions are

Normal right submodules and right ideals need not coincide in an arbitrary near-ring. Berman and Silverman (1) have shown that in a near-ring (N, +, ·) with a two-sided zero (i.e. x · 0 = 0 · x = 0, for all x ∈ N) a right ideal is also a right s

Right ideals and right submodules need not coincide in an arbitrary nearring. Let T0(G) be the near-ring of all transformations of a group (G, +) int itself that map 0 into 0. Theorem 1. If G is a finite group which contains mor than two elements, th
