However, oxygen radical chemistry may also play a useful role in(More)

The throughput of a satellite channel communication is depending upon the link protocol. It is well known that the “classical” HDLC protocol is inadequate when applied to satellite links instead of short terrestrial links. Several modifications have been proposed to overcome this problem. The present paper gives an analysis and evaluation of a new class of(More)
