The next subsections are dedicated to explain the valid assumptions that are used in the present investigation.
BO PVT property prediction algorithms, such as the Walsh Tower algorithm, are built around the presumably valid assumption that the total amount of stock tank oil (Nfg + Nfo + Np) and total amount of surface gas (Gfg + Gfo + Gp) would be conserved throughout the depletion process.
Finally, probably the least valid assumption is that the background intensity profile, in this case dominated by the weld geometry, is changing little compared to the change due to the pore.
The latter is a valid assumption, as in the supplementary material it is shown that the bone marrow activity concentration decreases with an effective half-life (73 h) that is shorter than the physical half-life of 89Zr (78.41 h).
Figure 10 shows the concentration profile of CO2 along the PVT cell, confirming that the infinite-acting boundary condition is a valid assumption under the test conditions.
Later, it will be shown that the infinite-acting boundary condition is a valid assumption under the test conditions.
The channel is spatially independent flat Rayleigh fading, which is a valid assumption when the antenna spacing is sufficiently large and the delay spread is small.
For these reasons, the frozen-in flow hypothesis proposed by Taylor (1938), interpreting the measured frequencies as pure Doppler shift due to the mean flow, is thought to be a valid assumption in the study of solar wind turbulence.
In the absence of research on this topic, a case fatality rate in the range 2.5-5% seems to be a valid assumption for the expected transition point.
This is surely a valid assumption for the RM; it may not be for the HtMM and, therefore, the possible introduced error on the elbow angle due to pronatoin/supination was estimated.
This is, however, not a valid assumption if the backhaul and access links are operated on adjacent carriers.
