The onset of oscillatory Marangoni convection in a semi-infinitely deep layer of fluid the problem parameters on the marginal curves and hence on the critical Marangoni number, frequency of oscillation and wavenumber for the onset of convection... I Hashim,SK Wilson - 《Zeitschrift Für Angewandte...
So while wave frequency refers to the number of cycles occurring per second, wave speed refers to the meters traveled per second. A wave can vibrate back and forth very frequently, yet have a small speed; and a wave can vibrate back and forth with a low frequency, yet have a high ...
6 (b) shows the spin-wave wavevector of the first four waveguide modes n=1 to n=4 as a function of the externally applied bias field for a fixed spin-wave frequency of 6GHz. For the calculations, a 2.2μm wide, 20nm thick waveguide made from Ni81Fe19 has been assumed, as has...
We then use this state-space form to investigate the stability of the thermoacoustic system, both in the frequency and time domains, using the flame position as a control parameter. We observe frequency-locked, quasiperiodic and chaotic oscillations. We identify the location of NeimarkSacker ...
Existence of quasi-periodic solutions with two frequencies of completely resonant, periodically forced, nonlinear wave equations with periodic spatial boundary conditions is established. We consider both the cases the forcing frequency is (Case A) a rational number and (Case B) an irrational number.被...
in the magnetic field of the light wave (ωB=eB/mc; where e, m, c and B and are respectively the charge and mass of the charged particle, speed of light and magnetic field of the electromagnetic wave) becomes of the order (or exceeds) the frequency (ω) of the wave itself i.e....
We explore a new asymptotic-numerical solver for the time-dependent wave equation with an interaction term that is oscillating in time with a very high frequency. The method involves representing the solution as an asymptotic series in inverse powers of the oscillation frequency. Using the new ...
Besides the permanent annual cycle (365 366days) and its second harmonic (181days), low-frequency oscillations with periods of 55 65 and 35 45days were found both in the mid-troposphere and at sea level, explaining a substantial number of the total variances in the relevant frequency bands....
