Therefore, it is important to realistically estimate the possible damage conditions due to underwater explosions in the design stage.
Furthermore, investigations using the model were carried out where the attaching force under the basemat was taken into account, in order to more realistically estimate the basemat uplift behavior.
We show that it is currently possible to realistically estimate variability of animal colours as perceived by them, something difficult to achieve with other traits.

The delaying effects of fine particle filtration à la Civan (1998) are then compared with the time delay of the fractional derivative model; thus, the fractional derivative order for this filtration is realistically estimated.
Modelling the skimming energetics of a 10 m span azhdarchid suggests that even an unfeasibly lightweight (50 kg) individual would lack the metabolic energy to skim-feed, and this assertion applies even more to a realistically estimated 200 kg individual [75].
However, presently available in vitro skin models have a too low barrier function for realistically estimating dermal absorption by the in vivo human skin.
