Various types of organic compounds have been detected in Jupiter, Titan, and cometary coma. It is probable that organic compounds were formed in primitive Earth and Mars atmospheres. Cosmic rays andâ€¦ (More)

We show that necessary and sufficient conditions for the existence of a semi-evenly partite star factorization of the symmetric complete tripartite digraph K~I,n2,n3 are (i) k is even, k 2 4 and (ii)â€¦ (More)

A new balanced file organization scheme of order two for binary-valued records is given which we call HUBFS2 (Hiroshima University balanced file organization scheme). It can be constructed for a wideâ€¦ (More)

We show that a necessary and sufficient condition for the existence of an Sk-factorization of the symmetric complete bipartite digraph K * , is m = n -~ 0 (mod k(k 1)).

In this paper, it is shown that a necessary and sufficient condition for the existence ofa Ckfactorization of K,.,. is (i) m = n = 0 (rood 2), (ii) k 0 (mod 2), k > 4 and (iii) 2n 0 (mod k) withâ€¦ (More)
