Eitan Altman,Tania Jiménez a production of over 468. 275 million tons (in 1988). Rice is attacked by a large number of pests and diseases which cause an enormous loss in its yield. Therefore, the major objectives in rice breeding are the development of disease resistance, tolerance to insects, adverse soil water, and drought

Classical queueing models, some general probability distribution, and the time it takes to transmit a packet is random as well distributed according to some other distribution. The fact that the transmission time varies may reflect a situation of a constant transmission rate but a varying size of a packet. The mathematical a
