## Period of Oscillation

the smallest interval of time in which a system undergoing oscillation returns to the state it was in at a time arbitrarily chosen as the beginning of the oscillation. Strictly speaking, the concept of period of oscillation is applicable only when the values of a quantity recur exactly over equal time intervals—for example, in the case of harmonic oscillation. However, it is also used in a broader and less strict sense for cases of approximately recurring processes.

If, when moving vehicle in rough terrain, such oscillations are constantly repeated, for example, with frequency f = 0.2 Hz (period of oscillation is 5 s), then the losses of power in shock absorbers of the vehicle are:
In our simulations, the membrane voltage x(t) contained two unperturbed cycles that are on the steady limit cycle such that the prestimulus HT amplitude is a(t + [P.sub.I]), where t [member of] (0, [P.sub.I]) and [P.sub.I] is the intrinsic period of oscillation. We used a 4th-order Runge-Kutta integration method for stiff differential equations and sampled the solution with the sampling time [DELTA]t, that is, using N = 1000, equally spaced, sampling points per cycle.
The reductions in the amplitude and period of oscillation result in a smoother force curve which implies verifying the validity of (8) and (10), indicating that a smooth force fluctuation can be achieved with the use of fuzzy-sliding control scheme.
where f--is a coefficient considering changes in the hardness of copper and random variation of the allowance; T--the period of oscillation of the cutting force, ms; [b.sub.p]--commutator plate thickness, mm.
Besides, the period of oscillation, the amplitude of oscillation, and guaranteed convergence rate can be accurately estimated.
The new aspect observed is the acceleration of the dynamics, where the period of oscillation is reduced by the initial eccentricity of the orbit of the spacecraft.
When the plant leaf oscillation amplitude reaches up to 30[degrees], up to 14% less of the Sun's radiation energy reach the leaf surface in a certain period of oscillation (Fig.
The major sources of error in the magnetic torque method are in the measurement of the period of oscillation of the magnet and also in the measurement of the coil currents.
"By measuring the period of oscillation, we could therefore detect chemical substances with molecular precision.
It has also been demonstrated that when the vibration in the earth caused by the seismic disturbance coincides with the natural period of oscillation, it reinforces the motion.
Starting at high frequencies (short relaxation times), the glassy zone is defined by little to no configurational rearrangement of the chain backbone in the period of oscillation. A high storage modulus typical of glassy, brittle solids is seen, with the tangent [delta] value near 0.1.
