(a silent system signal generated by the entry of a designated code into the arming station to indicate that the user is disarming under duress); panic alarms (an audible system signal to indicate an emergency situation); and hold-up alarms (a silent system signal to indicate that a robbery...
The sharpness of the duct is considered to be 1 point when there is no change in the local signal intensity of the duct, 3 points when the change in signal intensity is insignificant and the boundary is not clear, and 5 points when the signal intensity change is good and the boundary ...
Period, electrical conductivity, and signal attenuation are converted to dielectric permittivity [47]. Liquid water content is obtained as a function of the medium's dielectric permittivity with empirical formulas. This is discussed in Section 3.4. Because the CS650 is a time-domain reflectometer, ...
