Rational Unfoldings of
and Their Relation with Geometric
W. Kuyk (in real life, Willem Kuijk - here are a few other
of his many works) and
Applicandae Mathematicae, volume 19 (1990), pages 87-95.
In this paper, two theorems determine the locus B ('buoyancy locus') of the
centre of gravity of the displaced water of a ship with any number of 2n
sides, as a function of the arbitrary continuous curves that make
up those sides, and that generalize the classical wall-sided case
(n = 1).
Although the theorems may have interest from the pure geometrical point
of view, they have been obtained with a view to simulate
processes in biology that, in analogy to the self-righting of ships,
are self-regulating, such as the neural control of the body heat and
the servo-control of the heart rate.
