Kennelly, who was also responsible for introducing complex impedance, and Webster were the first to extend the concept of impedance into mechanical systems in 1920.
B. Virtual impedance method The coupling between the output active and reactive power of the conventional ωU-droop control can be mitigated by introducing virtual impedance [15], as illustrated in Fig. 8.
Not uncommonly, as in this instance, grips used to clamp specimens introduce an impedance mismatch with the input/output bars, and the design of the clamps may not be amenable to modification to yield an impedance match.
If JSPH-1 pH capsule system introduces an impedance electrode in container on the basis of fitful or smaller measure of capsule which would be a great improvement in diagnostic field of GERD.
Results derived from this model show that acoustic radiation depends on change in impedance as well as the absorption coefficient, and there is a possibility of reducing the radiation from vibrating surface by introducing an appropriate impedance surface.
It should be noted that the specific pressure characteristics of each formant were not changed by introducing the wall impedance.
The article shows how to introduce dynamic impedances in two traditional accessibility measurements using a current ordinary personal computer.
When initially testing the modulator, we realized that the radio was clipping the output of the DAC by introducing a low load impedance.
The obtained adaptive system fulfills the dual function of providing highly anisotropic static compliance while introducing large adaptive dynamic impedance, thereby effectively decoupling the static and dynamic structural properties.
This is based on the calculation of accessibility levels to the labour market for different zones of a given city, by introducing a function of impedance composed by travel time budget and the percentage of income spent on transportation.
Introducing the concept of integrated impedance to wide area protection, the principle of FEI based on wide area integrated impedance can be established [39], which can overcome the defects of the wide area current differential protection.
