In this paper the influence of a stationary white noise on the estimation of a sine-wave amplitude by means of the three-point Interpolated Discrete Fourier Transform (IpDFT) method is investigated.

The intricate, hidden processes that sustain coral life are being revealed through a new microscope developed by scientists ...

The LLSAW in lithium niobate on stress-free surface reveals rather high attenuation of the order of one dB per wavelength. Calculated resonant characteristics of a long IDT and dispersion curves of ...

These waves are at least twice as tall as the surrounding waves. They’re unpredictable. They can come from unexpected ...
