In the study, published in Physics of Fluids, the researchers developed a new equation by integrating two distinct mathematical models of magma flow.The results show that P-wave velocity decreases ...

A Wentzel–Kramers–Brillouin (WKB) approximation can be applied and reveals that the local wave vector still follows from Equation (11), whereas the pressure amplitude is proportional to the ...

Consider a complex signal composed of a sine wave and a sinc function as shown in Figure 3. Figure 3. The time domain representation of a complex signal composed of a sine wave and a sinc function.

On the other hand, the most severe power loss of 12.7% was recorded in the case of wave amplitude of 0.05 m, wavelength of 1.730 m, and wave frequency of 0.95 Hz.

To solve the evolution equations, ... of relevant asymptotic quantities to their values in the unperturbed space-time along ℐ − and ℐ + for an initial wave amplitude a = 10 .

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...

The circuit was successfully tested using a 1-kHz sine wave for the input with an amplitude of 4.5 V, and it produced a 1-V amplitude sine-wave output using a 1-V reference for the set point. See ...
