attenuation factor

The ratio of the incident radiation dose or dose rate to the radiation dose or dose rate transmitted through a shielding material. This is the reciprocal of the transmission factor.

Let us define the attenuation factor [alpha] = Im[[V.sup.2]]/[[absolute value of V].sup.2] (where V is a complex velocity [7]) that corresponds to the definition of the quality factor Q = 2[pi]E/[DELTA]E, where E is the wave energy and [DELTA]E is the energy lost per cycle due to attenuation [9].
Each parallel DBN-GC in the proposed ensemble deep learning model contains three important parameters: the weight coefficient of glia effect value a, the attenuation factor j3, and the glia threshold 9.
The [mu] factor is obtained from the energy registered for the study in the XCOM database [44], which exists for concrete and lead, where mass transmission coefficient is obtained and, hence, the attenuation factor.
This is understood as precipitation is a major attenuation factor in radio communications especially at high frequencies [6, 10, 11].
The attenuation characteristic can be described by the attenuation factor [K.sub.r]; then
where [alpha] is the attenuation factor and [beta] is the phase factor.
On the other hands, due to the frequency dependence of attenuation (high attenuation factor for high frequency components) , number of high frequency AE due to fiber breakage (550-650kHz) is drastically reduced for the results of 20 and 30 mm propagation lentgh (Fig.
This in turn increases the attenuation factor of the resonant voltage signal.
