Forced vibrations of a circular muscle ring
Bulletin of Mathematical Biology, 1973We consider the small radial displacement of a circular ring of cardiac muscle subjected to periodic forcing. The ring in question is that in the middle layer, at the transverse midsection, of the left ventricle. We show that the ring reacts in a periodic manner when forced in a periodic manner. This is accomplished by writing the differential equation

The forced vibration of strings has much in common with, on the one hand, their free vibration and, on the other hand, the forced harmonic motion of single objects. But there are also peculiarities, some of which are investigated here. It is found useful to distinguish two kinds of forcing; and some suggestions are made about vibrating strings in such ...

Grip Force Estimation by Emitting Vibration
Adjunct Publication of the 30th Annual ACM Symposium on User Interface Software and Technology, 2017We propose a method for determining grip force based on active bone-conducted sound sensing, which is an active acoustic sensing. In our previous studies, we estimated the joint angle, hand pose, and contact force by emitting a vibration to the body. We aspired to expand to an additional application of an active bone-conducted sound sensing, thus, we ...

The experimental determination of the response curves for forced vibration with velocity damping, using a moving-coil galvanometer, is described. The mechanism for producing a sinusoidal emf, of continuously variable frequency ranging from zero to 0.4 cy/sec, is described, together with a method for the determination of the phase angle between the ...

Magnetoelastic forced vibrations of a conducting plate caused by either nonstationary external forces of nonelectromagnetic origin, or with the help of a nonstationary harmonic magnetic field, are examined. The following results are conditioned by the interaction of mechanical and electromagnetic processes in oscillating thin bodies.

Forced Damping Vibration of a Cantilever Beam
Sensors and Microsystems, 2008Forced damping vibration strategies have a paramount relevance in all those cases where surface vibrations represent disturbances. Knowing that surfaces show different resonant modes of vibration related to their geometry we have selected a cantilever beam that has only one principal resonant frequency.

Lattice Vibrations and Harmonic Forces in Solids
Proceedings of the Physical Society. Section B, 1957A discussion is given of the interpretation in terms of harmonic forces between atoms of the phonon frequency against wave vector data which is provided by the results of both X-ray and neutron scattering experiments. A knowledge of the phonon polarization vectors is required before a calculation of the components of the interatomic harmonic force ...
