For tapping-mode applications, where high-speed scanning is the goal, Q-control
was able to reduce the scan speed that limits relaxation time [27.52]. A large

Understanding Radiography
This is taken into account by means of a quality factor: rem = rad x (quality factor)
X-rays have a quality factor of 1 (see Figure 203). So we have the convenient
situation that for diagnostic x-rays 1 R (approx. = ) 1 rad, which (approx = ) 1 rem.
The Quality-factor is independent of the frequency. The process is often
expressed in terms of the dissipation factor Q~l, which characterizes the
absorbent properties of the subsurface. The logarithmic decrement A = n/Q is the
attenuation per ...

Another important reason to worry about the reduction of the radiation resistance
is that it contributes to an increase in the antenna's radiation quality factor (Qr). (In

We will model the lossy inductor as an ideal inductor in series with a resistor of
value rs. The ratio of the inductive reactance, XL, to this resistance value is the
quality factor, Qv, where the subscript denotes "unloaded Q" or component Q. (
