Characteristics of a 9mm triple-beam tuning fork resonant sensor [PDF]

open access: yes, 2007
This paper describes the design and testing of the first miniaturised metallic triple-beam tuning fork resonant sensors for use in force, pressure and torque measurement applications. The new devices with 9mm length vibrating tines have resulted in over

The effects of kinematic condensation on internally resonant forced vibrations of shallow horizontal cables [PDF]

open access: yes, 2007
This study aims at comparing non-linear modal interactions in shallow horizontal cables with kinematically non-condensed vs. condensed modeling, under simultaneous primary external and internal resonances.

Dual-Band Band-Pass Filter with Fixed Low Band and Fluidically-Tunable High Band

open access: yesSensors, 2017
In this work, we present a dual-band band-pass filter with fixed low-band resonant frequency and tunable high-band resonant frequency. The proposed filter consists of two split-ring resonators (SRRs) with a stub and microfluidic channels.

Middle ear resonance in infants: Age effects

open access: yesInternational Archives of Otorhinolaryngology, 2012
Introduction: The resonant frequency is the probe frequency in which susceptance is 0 due to the neutralization of the forces of mass and stiffness components that control the middle ear.
