Simulation of a non-invasive glucometer based on a microwave resonator sensor
(Institute of Physics Publishing, 2013-09)
In this paper a simulation of a microwave resonator sensor for constructing a noninvasive blood glucose meter is presented. A relationship between changes of the dielectric permittivity of the blood and the frequency ...
Turning a loudspeaker into an active Helmholtz resonator: Underlying law, principle and design methodology
(2018-10-13)
This paper is concerned with how to turn a moving-coil loudspeaker into an active Helmholtz resonator (AHR): that is, an active noise control loudspeaker used in conjunction with a microphone and a feedback controller to ...
Analytical study of the nonlinear behavior of a shape memory oscillator: Part I-primary resonance and free response at low temperatures
(Springer, 2010-03-01)
In this work, the response of a single-degree-of-freedom shape memory oscillator subjected to the excitation harmonic has been investigated. Equation of motion is formulated assuming a polynomial constitutive model to ...

Micro-inverter for integrated grid-tie photovoltaic module using resonant controller
(Wiley-Blackwell, 2014-05-01)
Two-stage isolated converters for photovoltaic (PV) applications commonly employ a high-frequency transformer (HFT) on the DC-DC side, submitting the DC-AC inverter switches to high voltages and forcing the use of ...
Double resonance capture of a two-degree-of-freedom oscillator coupled to a non-ideal motor
(2016-09-01)
This work presents the development of a discrete parameter model consisting of a concentrated mass which is supported by a set of springs and dampers positioned in two orthogonal directions, such that the mass can move ...
The asteroid population in g-type non-linear secular resonances
(Oxford Univ Press, 2017-07-01)
Non-linear secular resonances of g-type, i.e. involving the frequency of precession g of the asteroid pericentre, can affect the proper eccentricities of asteroids in resonant or near-resonant configurations. We first ...
A comparison between cutting torque and resonance frequency in the assessment of primary stability and final torque capacity of standard and TiUnite single-tooth implants under immediate loading
(2004-01-01)
Purpose: In this study, standard Brånemark System implants and Brånemark TiUnite implants were evaluated regarding primary stability and placement torque. The correlation between placement torque and primary stability as ...
