Torsional Oscillations of Relativistic Stars with Dipole Magnetic Fields [PDF]
, 2006 We present the formalism and numerical results for torsional oscillations of relativistic stars endowed with a strong dipole magnetic field. We do a systematic search of parameter space by computing torsional mode frequencies for various values of the ...

Torsional Alfvén waves: magneto-seismology in static and dynamic coronal plasmas [PDF]
, 2011 Aims: We study the properties of torsional Alfvén waves in coronal loops so that they may be exploited for coronal seismological applications. Methods: The governing equation is obtained for standing torsional Alfvén waves of a dynamic, gravitationally

A strategy for delivering high torsionality in longitudinal-torsional ultrasonic devices [PDF]
, 2011 A composite longitudinal-torsional vibration mode has applications in ultrasonic motors, ultrasonic welding and ultrasonic drilling. There are two ways to obtain this vibration behaviour using a single transducer, namely (i) coupling of a longitudinal ...

Comparison of Longitudinal-Mode and Longitudinal- Torsional Mode Ultrasonic Bone Biopsy Devices [PDF]
2018 IEEE International Ultrasonics Symposium (IUS), 2018 Previous research by the authors has demonstrated the efficacy of an ultrasonic bone biopsy device that operates in a longitudinal (L)mode. Ultrasonic longitudinal-torsional (L-T)coupled vibration has proven successful in several applications including ultrasonic surgical devices.

Coupling of torsional modes in the Earth [PDF]
Geophysical Journal International, 1983 Summary. The effect of modal coupling is examined for torsional eigenvibrations of an anelastic earth with oceanic and continental structure. While a coupling effect is hard to observe in the eigenspectrum, some eigenfunctions show significant coupled energy into a secondary neighbouring multiplet.
