| The focus of this dissertation is the small free vibration of thin elastic hyperboloidal shells of revolution. |
| Initial data are prescribed on the blue parts, i.e. on a hyperboloidal hypersurface and the part of which is in its future. |
| These members complete the hyperboloidal structural connections to make the new structural principle operate. |
| For general hyperboloidal gears, let us now calculate and in the same way in terms of the velocity ratio. |
| He has a Parisian optician produce hyperboloidal lenses for a demonstration, but the lenses are a failure. |
