This paper introduces a frequency-domain method of structural damage identification.
Similarly, the Fourier transformed response of the motor is given by (6) χ ^ X = ω 2 ω X - i ω χ ^ A c. The motor is a low-pass filter, i.e. its dynamics introduces a frequency-dependent response, which is constant below the characteristic frequency ω X = k + * + k - * of the motor due to the steady-state switching rates k + * and k - *.
The effects of initial imperfection from a homogeneous state are taken into account by introducing a frequency distribution of the initial void ratio.
Moreover, some relevant frequency measurement methods are introduced, a frequency measurement method based on dynamic output characteristics has been proposed for the purpose of investigating the modulated output signal of resonant vibratory gyroscopes.
It can be performed by introducing a frequency domain window (see Figure 6).
We have modeled both domains as being ohmic, i.e. their impedivities (z=rho) are only real valued, but z can be made complex by introducing a frequency dependence [34].
In subjects where coherence phase originally appeared constant at different frequencies, cooling appeared to displace phase upwards, but without introducing a frequency dependence.
In our previous work [7], we have introduced a frequency-aware channel access protocol, D-Fi.
The proposed technique not only introduces a sophisticated frequency stabilization in deregulated power systems but also offers a smart energy management control of SMES.
The algorithm introduces a banded frequency sweep procedure, during which a series of digital filters are designed to process the original signal.
The proposed PZT-based actuator mechanism introduces a high frequency, lightweight, precise position solution for cylinder-by-cylinder variable valve timing.
