Numerical results show that direct transmission by asymptomatic infected individuals and indirect transmission via free-living viruses in contaminated environments are important factors which contribute to new HFMD infections.
From Figures 2 and 5, we observe the proposed SRS and MRS schemes perform better than the direct transmission in terms of OP and IP aspect, and the SRT performance improves when [P.sub.d] = 0.99.
As seen from Figures 3-7, the two proposed schemes AF1 and AF2 perform significantly better than the direct transmission DT in terms of outage and spoofing detection, and AF1 achieves the best performance among the three schemes as expected.
The cooperative transmission time [T.sub.coop] and the direct transmission time [T.sub.direct] are computed as
The authors in [13] evaluated the performance of coded modulation scheme based on LDPC codes considered direct transmission over additive white Gaussian noise (AWGN) and flat Rayleigh fading channels.
Firstly, when B-ACK mode is used, direct transmission time, [T.sub.SD], is given by
In this work, we simulate, analyze, and evaluate the performance of direct transmission (DT), opportunistic cooperative transmission (OCT), and the proposed CF-OCT based on activity probability.
Although cooperative communication promises to increase the capacity, an improper selection of relay node can result in an even smaller capacity than that under direct transmission. Therefore, the assignment of relay nodes plays a critical role in the performance of cooperative communication [2, 3, 6, 13, and 17].
Despite this apparent evidence of direct transmission, the virus's transmissibility remained "limited and non-sustainable," said the paper.
To this the leaders are said to have told the chairman that he could turn the direct transmission off if he felt that was necessary.
The sources revealed that the front-runners to become the 97th Armenian Patriarch of Jerusalem, in a direct transmission from the first patriarch, Abraham, are the Grand Sacristan, Archbishop Nourhan Manoogian and Director of Ecumenical Relations, Archbishop Aris Shirvanian, the current Locum Tenens.
Khoja welcomed the proposals, saying that the direct transmission of the Taraweeh (post-Isha) and Tahaggod (late prayer) in the nights of Ramadan will remain as scheduled over the previous years.
