The quality factor (Q) of the resonator can be characterized as the frequency of the resonator divided by the bandwidth of the resonator. where the resonance frequency and bandwidth must be given in the same units. The Q factor formula differs for each type of circuit. Q (Quality factor) is an unitless quantity. Quality factor can be defined as “Ratio of Energy stored by inductor to energy dissipated by resistor”; which comes to The radiation weighting factor is an estimate of the effectiveness per unit dose of the given radiation relative a to low-LET standard. Before 1990, dose-equivalent quantities were defined in terms of a quality factor, Q(L), that was applied to the absorbed dose at a point in order to take into account the differences in the effects of different types of radiation.

Since, there is an extensive literature on the Q factor for antennas, see e.g. , [2,3,6,7,14], only some of the results are given here. Figure 22 C shows a global quality factor that represents the minimum degree of inversion in the full offset range of ± 4 kHz. The global quality factor that is shown in Fig. 22 D as a function of the flip angles α and β is defined as the minimum of the quality factor q m (v i, v j) [Eq. (230)] in the offset range of ±4 kHz.

Thus, In this case also, the Q is a dimensionless quantity since the unit of both reactance and resistance is the same and it is Ohm. 2019-10-22 · While the quality factor has been identified in the literature (including papers such as “Buffett’s Alpha,” “Global Return Premiums on Earnings Quality, Value, and Size,” and “The Excess Returns of ‘Quality’ Stocks: A Behavioral Anomaly”), and there are now a number of investment vehicles with quality strategies (such as the iShares Edge MSCI USA Quality Factor ETF, or QUAL For example, alpha particles have a quality factor value of approximately 20. The conventional unit for dose equivalent is the rem, and the Sl unit is the sievert (Sv). When the quality factor is 1, the different relationships between dose equivalent (H) and absorbed dose (D) are. H(rem) = D(rad) H(Sv) = D(Gy).

We'll only discuss a few of them here. It's not only in mechanical systems, such as pendula or shock absorbers, that this "Q" factor appears. Quality factor, Q Reactive components such as capacitors and inductors are often described with a figure of merit called Q. While it can be defined in many ways, it’s most fundamental description is: average power dissipated energy stored Q=ω Thus, it is a measure of the ratio of stored vs.

In this case, the ICRU decided that the quality factor and the distribution factor were dimensionless and, therefore, it was clear that both the absorbed dose and the dose equivalent must have the same units in the SI system. Q means Quality Factor, a factor which determines the efficiency of an LCR circuit.

I'm assuming that these units are very similar. most likely have a true power factor (W/VA) that is less than displacement power factor (cosine of angle between voltage and current).
