Whittaker–Hill equation, Ince polynomials, and molecular torsional modes
International Journal of Quantum Chemistry, 2009AbstractWe present an analysis of the Whittaker–Hill equation in view of its usefulness in quantum mechanics when periodic potentials are involved. The transformation due to Ince leads to polynomial solutions which have not attracted much attention so far in the applications. With respect to Mathieu equation, here we have an additional parameter, which

Torsional and Lateral Resonant Modes of Cantilevers as Biosensors: Alternatives to Bending Modes
Analytical Chemistry, 2013We show here novel cantilever designs that express torsional and lateral modes exhibit excellent mass-change sensitivity to molecular self-assembly on gold (75-135 fg/Hz) which is superior to that of widely investigated bending modes. Lead zirconate titanate (PZT) millimeter-sized cantilevers were designed with two types of anchor asymmetry that ...

Torsional mode magnetoelastic resonance in ferromagnetic amorphous wire
Journal of Applied Physics, 1995A torsional pendulum has been built using a stress relieved FeSiB amorphous wire. Torsional motion is magnetoelastically induced by means of the simultaneous application of longitudinal Hz and circular Hφ magnetic fields. The experimental setup allows one to determine both the torsional deformation and the changes in the longitudinal magnetization Mz ...

Rod-Type Torsional-Mode Concentrators
1969In this chapter, a number of relations needed for practical calculations in the design of torsional-mode focusing rods (concentrators) are given on the basis of the solution of the wave equation for the torsional vibrations of an inhomogeneous rod.

Architecture of torsional gyroscope having robust sense mode
Journal of Micro/Nanolithography, MEMS, and MOEMS, 2015An architecture of a torsional gyroscope having robust sense mode is reported. The robustness is achieved by utilizing dynamic amplification of torsional oscillations in the sense oscillator. The frequency response of the sense oscillator, which essentially is a 2-degree-of-freedom (DOF) one, has two resonance peaks and a flat region between the peaks,

New cuts for torsional mode quartz crystal resonators
1993 Proceedings IEEE Ultrasonics Symposium, 1993This paper describes new cuts for torsional mode quartz crystal resonators, which are called lTT(Y)-cutr. The object of this paper is to propose new cuts for torsional quartz crystal resonators with a zero temperature coefficient and to clarify their frequency characteristics, frequency temperature behavior and electrical equivalent circuit parameters.

Elements of Longitudinal — Torsional-Mode Vibration Systems
1969Longitudinal—torsional-mode vibration systems are rod systems, which, when driven in a longitudinal mode, are capable of generating a torsional vibration component by virtue of a certain inhomogeneity in the cross section of the rod.

Torsional Alfvén modes in dipole and toroidal magnetospheres
Planetary and Space Science, 1988Abstract Propagation of torsional Alfven waves in the magnetosphere is examined for two models of the Earth's magnetic field, one where the field is toroidal, the other being a dipole field. Both models yield magnetically guided torsional wave modes which are strongly localized in all directions transverse to the steady magnetic field. The transverse
