A proper cost functional is a mathematical expression giving the traveling time as a function of the speed, geometrical considerations, and initial conditions of the system.
In cases where no particular name arises from geometrical or historical considerations, the name of a star is used instead.
The tabular values, however, must be determined from measurements or atmospheric models that derive from geometrical and physical considerations of Earth and its atmosphere.
In 1937, MacAdam suggested a "modified uniform chromaticity scale diagram", based on certain simplifying geometrical considerations:
Beginning from here, Heliade Rădulescu develops a kind of cosmology, by means of naïve although ingenious geometrical considerations.
From geometrical considerations, the resultant airspeed flow and the angle of attack are calculated as follows:
Tertiary structure is the locations of the atoms in three-dimensional space, taking into consideration geometrical and steric constraints.
With this approach, the original geometrical consideration is not necessarily obvious, but it is a much quicker way to get at the same algebraic result.
However, these systems still require an ablator, and the accuracy and geometrical considerations are even more important.
Due to geometrical considerations, smaller cycloalkenes are almost always the cis isomers, and the term cis tends to be omitted from the names.
