Q factor

n
1. (Electrical Engineering) a measure of the relationship between stored energy and rate of energy dissipation in certain electrical components, devices, etc, thus indicating their efficiency
2. (Nuclear Physics) Also called: Q value the heat released in a nuclear reaction, usually expressed in millions of electronvolts for each individual reaction. Symbol: Q
[C20: short for quality factor]

Importantly, Choi noted, neither cavity has to meet rigorous design requirements for efficiency or indistinguishability as traditional cavities, called the 'quality factor (Q-factor)'.
In our most recent paper (Vondrak and Ron, 2017) we proposed a new method of determining the parameters (period T, Q-factor) of Free Core Nutation that is not part of the IAU 2000 model of nutation, and therefore present in observed celestial pole offsets (CPO).
The simulation results have shown not linear dependence between the tip length and quartz tuning fork oscillation amplitude, Q-factor and frequency difference.
A flexible wavelet transformation proposed by [25], namely, tunable Q-wavelet transformation (TQWT), controls the transformation of a discrete time signal by an easily tunable variable called the Q-factor. The TQWT solved the primary limits of the wavelet filter banks by providing a tunable Q-factor that controls the number of the oscillations of the wavelet transformation.
The response is that of a resonant detector, peaking at [[omega].sub.0] and with half the Q-factor of an isolated element.
The performance of the both systems was evaluated in the terms of Q-factor. The value of Q-factor equal to 16.95 dB, corresponding to BER equal to [10.sup.-12] was chosen as a preliminary threshold [3].
The third chapter is devoted to the error rate BER and related Q-factor. The fourth chapter describes EDFA and SOA optical amplifiers and their basic principles.
The resonant frequency and Q-factor have been calculated from [12]
The Q-Factor. Q-factor [31] offers a suitable measure of the overall system performance and can be used based on optical eye diagram.
Sparse signal representation, morphological component analysis (MCA), and a tunable Q-factor wavelet transform (TQWT) are adopted in the RSSD algorithm [11].
The integrated wireless power coils feature an industry-leading thin design and the highest power transfer efficiency (Q-factor) of any wireless charging solution on the market today.
