TL;DR: In this article, the instantaneous moment of inclination (M) and the instantaneous angle of inclination alphai are constantly and approximately determined for a period of time sufficient for the inclination angle to be calculated as a function of the moment d 'inclination applied and so that we can calculate the metacentric height on this basis.
Abstract: The metacentric height of a vessel (GM) is determined by the formula (I), in which GM = the metacentric height in the direction of inclination, M = the moment of inclination applied, alpha = the angle of inclination , delta = the density of the water, g = the acceleration of the weight, Vo = the volume of the displacement. By cyclically applying a tilt moment for a long period of time. Likewise, the instantaneous moment of inclination (M) and the instantaneous angle of inclination alphai are constantly and approximately determined for a period of time sufficient for the inclination angle to be calculated as a function of the moment d 'inclination applied and so that we can calculate the metacentric height on this basis.

TL;DR: In this paper, a tuned borehole gravity gradiometer comprises a dipole mass system having means for selectively tuning the sensitivity of the gravity gradient to detect variations in the earth's gravity gradient within a borehole.
Abstract: A tuned borehole gravity gradiometer comprises a dipole mass system having means for selectively tuning the sensitivity of the gravity gradiometer to detect variations in the earth's gravity gradient within a borehole. The tuning means includes varying the metacentric height of the dipole mass system by selectively varying the center of gravity of the dipole mass system with respect to the metacenter of the dipole mass system.
