→ skos:note → "Since flow behaviour in the grey zone cannot be predicted, the
parameters of these areas are usually chosen empirically. It is not always
possible to carry out a sufficient number of experiments and therefore these
areas are usually not sufficiently optimised, resulting in increased losses
and resistance. Consequently, the elimination of grey areas indirectly
leads to an increase in conductivity through better optimisation."@en
→ skos:definition → "Transition from a flow that contains areas in which its
behaviour cannot be predicted with sufficient accuracy to a flow that is
free of such areas."@en
→ skos:example → "A grey area is also the area where the flow of advertising
information interacts with potential consumers, causing advertising costs to
be overspent and ineffective. This area can be eliminated by various means,
such as targeting ads to supposedly homogenous groups, for example, Barbie
dolls are advertised in cartoons targeted at girls, or the charms of
military service in the commercial breaks of martial arts movies."@en, "Fishing. A school of fish cannot be seen underwater and its
behaviour cannot be accurately predicted, so ensuring a steady flow of fish
from the sea to the fishing vessel is difficult -- causing many unnecessary
costs in unsuccessful net casts and idle crossings.<br/> Sonar has been used
to eliminate the grey zone - it is now possible to see whether fish are
present and to target the trawl."@en
