The Kirchhoff-Love theory and the theory of high frequency, long wave vibrations are used in the vicinity of zero frequency and in the vicinities of the thickness resonance frequencies, respectively.
The frequency sweeping technique with small increment steps in the vicinity of resonant frequencies was employed to construct frequency response functions at different shaking levels from which the natural frequencies, damping ratios and mode shapes were identified for several vertical, mixed vertical torsional and lateral modes.
It is also found that cubic damping nonlinearity may cause lower time-averaged transmitted and dissipated powers at the interface in the vicinity of resonant frequency.
We consider various experimental possibilities and focus on an atom embedded in a photonic crystal designed to have a band edge in the vicinity of the frequency of the emitted light.
This method uses formulas which involve differences between the frequency response data at three frequencies in the vicinity of a natural frequency to estimate this natural frequency together with the damping and the residue.
The long-wave models (the Kirchhoff Love theory (or its refinement) and the long-wave high-frequency approximation) are exploited in the vicinities of zero frequency and thickness resonance frequencies, whilst the model of a fluid-loaded flat elastic layer is utilized outside the aforementioned vicinities.
The CHIEF method is adopted to enhance the quality of the solution, particularly in the vicinity of irregular frequencies.
The retrieval results reveal that the effective refractive index of the e-shape structure is nearly negative in the vicinity of resonant frequencies.
It is shown that this form of solutions may offer some conveniences in studying mechanical and electrical properties of the system in the vicinity of resonance frequencies.
For a layer with the perfectly smooth periodic corrugation, the equation of the axial wave motion is solved by the method of multiple scales in vicinity of critical frequencies.
The occurrence of intrinsically bent DNA (caused by runs of adenine base pairs known as A-tracts), triplex-forming and quadruplex-forming sequences has been noted in the vicinity of high-frequency mitochondrial genome deletions.
