Indian Journal of Dental Research, 2011 Initial stability at the placement and development of osseointegration are two major issues for implant survival. Implant stability is a mechanical phenomenon which is related to the local bone quality and quantity, type of implant, and placement technique used.

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

Research Progress of Locally Resonance Acoustic Metamaterials [PDF]
E3S Web of Conferences, 2021 Bragg scattering phonon crystal and locally resonant acoustic metamaterials were introduced. In order to generate noise reduction, the lattice constant of Bragg scattering phonon crystal should be of the same order of magnitude as the wave length of the ...

Universality in three-frequency resonances [PDF]
Physical Review E, 1999 We investigate the hierarchical structure of three-frequency resonances in nonlinear dynamical systems with three interacting frequencies. We hypothesize an ordering of these resonances based on a generalization of the Farey tree organization from two frequencies to three.

Middle ear resonance in infants: Age effects
International 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.

Digital Resonant Controller based on Modified Tustin Discretization Method
Advances in Electrical and Computer Engineering, 2016 Resonant controllers are used in power converter voltage and current control due to their simplicity and accuracy. However, digital implementation of resonant controllers introduces problems related to zero and pole mapping from the continuous to the ...
