The phrase "a significant underestimation of" is correct and usable in written English.
It can be used when discussing a situation where the true value or impact of something has been greatly undervalued or miscalculated.
Example: "The report revealed a significant underestimation of the project's costs, leading to budget overruns."
Alternatives: "a considerable misjudgment of" or "a major undervaluation of".
This simplification leads to a significant underestimation of strength in combined bending and compression.
Large gauge vacuum-assisted core needles have improved accuracy; but a significant underestimation of malignancy remains.
Our study suggests a significant underestimation of sea-level rise impacts predicted by commonly used models on coastal wetlands affected by man-made flow restrictions.
These results indicate that a significant underestimation of groundwater recharge can be introduced if this enhancement effect is neglected in the CMB application.
A satisfactory agreement between experimental and predicted fatigue limits was found for unpeened gears, whereas for peened specimens a significant underestimation of fatigue strength was found.
The results suggest that under near-fault conditions, when the directivity pulse has substantial content near the frequency of the second convective mode, current provisions may lead to a significant underestimation of the maximum height of the sloshing wave.
In conclusion, PWP can be estimated by the Doppler early peak flow velocity to flow propagation velocity ratio, although a significant underestimation of PWP may be observed in patients with a restrictive filling pattern and preserved ventricular function.
The study demonstrates how low-resolution bias can result in a significant underestimation of burned areas and/or a shift in the seasonal burned area profile in areas where mosaic burning occurs.
Experiments were conducted using a range of soot-in-oil mixtures according to the widely used thermogravimetric standard method ASTM 5967-08 which showed a significant underestimation of the soot content in the oil as a result of carbon mass loss due to combustion and/or pyrolysis effects.
Although prior research indicates that the assumption of zero rotational stiffness of the column base-plate connection could result in a significant underestimation of the overall lateral stiffness of horizontally loaded moment frames (leading to less economical designs), there has been no systematic study to investigate this issue.
As a result, the following problems of the evaluated libraries were pointed out: the cross-sections of the (n,2n) reaction in JENDL-3.3 for lead isotopes are too large and cause a significant underestimation of the neutron flux above 10 MeV, which appeared in the analysis of the above experiment.
