(4) is independent of the sign of the wavenumber, the main conclusion regarding the horizontal spatial profiles of the modes holds without modifications. 1D topological pumping Figure 1a, b show a planar array of acoustic cavities coupled horizontally and vertically through channels. Each cavity has...
Fractals are self-similar structures (i.e., next generation of a fractal can be constructed by combining copies of its previous generation) widely represented in universe1, whose unusual internal composition finds its manifestation in new physical phenomena observed in solid-state physics, acoustics, ...
The nonlinear growth of these oscillations leads to spurious energy buildup in the high-wavenumber region of the spectrum, and contaminates the flow field. Consequently, the growth of the integral length scale is found to be numerically stunted, well before the intended final Reynolds number is ...
As per the classical diffraction theory, the relationship between the incoming wave and ann-th order diffracted wave reads\({k}_{0}\left(\sin {\theta }_{r}-\sin {\theta }_{i}\right)=nG\), which is also known as the generalized law of reflection. Here,k0, is the wavenumber in ...
Here, the case of kR = 0.245, kA = 0.19 and d/R = 10.0 is selected, where k is the wavenumber, R the radius of the cylinder, d the water depth, and A is half of the wave height, which corresponds to the long-wave regime and moderately steep wave events in finite water depth....

the local linear compact reconstruction without limiter can achieve a spectral-like resolution at large wavenumber than the well-established compact scheme of Lele with globally coupled flow variables and their derivatives. For nonlinear gas dynamic evolution, in order to avoid spurious oscillation in di...
wavenumber k µ ; the perturbation of the correction is also calculated to the leading (quartic) order in k µ . After we impose the transverse traceless conditions on the perturbation (again to leading order in k µ ): h = 0, k ...

In this study, 200 biomass samples were used to determine higher heating value (HHV) and 120 biomass samples for analyzing ultimate analysis parameters using near-infrared spectroscopy within the full wavenumber range of 12489.48 - 3594.87 cm-1. The samples were grounded, and five different types ...
