The frequency distribution of research papers and patents according to sex: The case of CSIR, India. Scientometrics, 1992, 24(3), 449-469.Lemoine, W. (1992b). The frequency distribution of research papers and patents according to sex: The case of CSIR India. Scientometrics, 24(3), 449-...
A relative frequency distribution shows the proportion of the total number of observations associated with each value or class of values and is related to a probability distribution, which is extensively used in statistics. From: Statistical Methods (Fourth Edition), 2022 ...

However, if they are extracted parallel to the field in a low pressure discharge the electron velocity distribution is far from Maxwellian and equation (3) has no meaning. The ion current density can be estimated however, on the following basis. Ions falling to the cathode partially neutralize...
Monitoring and preventing coal-rock dynamic disasters are vital for safe mining. To investigate the time–frequency features of induced charge signals with coal damage and failure of roadways, the generation mechanism of free charge in loaded coal is ana
As a relevant example, we first consider a simulation of a complex terahertz spectrum consisting of several lines, similar to the type of signal that is highly relevant for astronomy (for example, in measuring the spectral line energy distribution of carbon monoxide36). For astronomical signals, ...
Frequency content refers to the distribution of signal amplitudes across different frequencies, often analyzed using techniques like fast Fourier transform (FFT) to understand the frequency components present in a signal. AI generated definition based on: Digital Signal Processing (Third Edition), 2019 ...
Marginal frequency refers to the frequency component of a signal in the time-frequency distribution, where the integrals along specific lines in the time-frequency plane correspond to the powers of the signal transformed at certain angles.
