Frequency is defined as the number of waves that pass a fixed point in unit time. Learn the concepts of frequency, time period and angular frequency along with definition and formulas at BYJU'S.
and \(\omega \) are periodic. we then show that such oscillation of the body induces time-periodic motion of the fluid with the same period as we would expect. one can also put a periodic external force in the equation of motion, however, it is assumed to be absent for simplicity. ...
59 The presence of oxygen was found to promote an increase in the rates of oxidation of COads, but not change the velocity of formation of COads. Also, the oscillation patterns, both chaotic and periodic, displayed a fluctuation in amplitude and had their period doubled. As for the presence...
Astronomers have observed one particular cloud and have noted that over a period of approximately five years it moved 2 milliarcseconds (mas). An arcsecond is 1/3600 degree. So, a mas is 2.78×10−7 degree or about 4.85 nanoradians. Thus moving only twice this angle in five years ...
For example, we allow both translational, \\({\\varvec{\\xi }}\\) , and angular, \\({{\\varvec{\\omega }}}\\) , velocities of \\({\\mathscr {B}}\\) to depend on time, and do not impose any restriction on the period T nor on the averaged velocity, \\(\\overline{{\...
velocity and micro-rotation, the volume flow rate and the micro-rotation intensity remain unchanged; when the electric oscillation frequency is higher (greater than 1), with the increase of the electric oscillation frequency, the amplitudes of the micropolar fluid electroosmotic flow velocity and ...
(x−xn)/Λnmod 2πin thexaxis, wherein the period and shifted displacement of the grating areΛn = 2π/knand Δxn = ϕn/kn, respectively (Supplementary Fig.1). The phases for generating STB vortices with topological charges ofl = 10, 25, 50, and 100 are shown ...
(3), there is no accumulated mass flux through the system in a time period t0 = d/v0 (Fig. 2b). Thus, we have C = 0 (see Supplementary Fig. 1 for the effects of a nonzero C) and can solve for the velocity field as v(χ) = [ρ(χ) − ρ0]v0/ρ(χ). The 1D ...
The argument that clusters must be bound and stable comes from the distribution of galaxy velocities within the clusters. The dynamical time scale, also called the crossing time, is the period of a galaxy orbit through the center of the cluster potential. The characteristic time scales are of ...
Error ratio is simply the basic BER, which is the counted error bits divided by the total number of bits received within the gating period ΔT; error-free seconds indicates the time interval within which no error occurs; and percent of unavailability is the percentage of the extended error ...
