Frequency Response Analysis of Parametric Resonance and Vibrational Stabilization

2020 American Control Conference (ACC), 2020
Periodically time-varying models are found across nature and engineered systems, from fluid dynamics, structures and MEMS devices to quantum mechanics and astrophysics. Such systems are known to exhibit parametric resonance, a kind of instability caused by fluctuating model parameters.

Resonance Frequency Analysis in Assessing Implant Stability: A Retrospective Analysis

The International Journal of Prosthodontics, 2019
To retrospectively assess implant stability quotient (ISQ) values in patients who were followed up between 1998 and 2014 and to evaluate any correlations between ISQ and clinical parameters, such as change in marginal bone level (MBL).A total of 173 participants (65 men and 108 women; age range 21 to 85 years) and 383 implants were included.

Analysis of the resonant frequency of the octagonal split resonant rings with metal wires

Applied Optics, 2010
The resonant frequency determined by octagonal split resonant rings (SRRs) is presented and analyzed. The simulated results show that the resonant frequency improves when the opening size of the SRRs becomes larger, and that enhancement of the coupling degree can improve the resonant frequency and widen the band.

Assessment of Stability of Craniofacial Implants by Resonant Frequency Analysis

Journal of Craniofacial Surgery, 2016
Implant stability is a principal precondition for the success of implant therapy. Extraoral implants (EO) are mainly used for anchoring of maxillofacial epithesis. However, assessment of implant stability is mostly based on principles derived from oral implants.
