E(X) is also referred to as the mean of X and is often denoted by μ or μx. You may find it helpful to think of the expected value of X as the center of mass of the frequency function. Imagine placing the masses p(xi) at the points xi on a beam; the balance point of the...
What Does It Mean To Be Sex Positive? That said, Singh notes that a lot of asexual people might not want to have sex at all, or might not want to have sex “with the same frequency or the same intensity” as an allosexual person. Like most things in life, it all depends on the...

When reading about time-domain spectroscopies, it is stated that via the Fourier transformation of a pulse we can obtain its frequency domain information (as you can see in the figures below). This contradicts my instinctive idea of frequency, which is one of repetition. I have alwa...
While calculating any metrics requires time and good documentation, MTBF is relatively easy. Considering all the benefits a company can achieve by having a clear understanding of MTBF makes the effort worthwhile. Improves the reliability of your assets which decreases the frequency of downtime and ...
Frequency is one of the characteristics of waves such that it describes the number of cycles of waves per second. This, therefore, can be related to the wavelength of the wave, such that λ=vf, where v is the velocity of the wave and f is the frequency....
(AI and VI) were anal. Neither AI prevalence nor frequency varied substantially by any participant or study characteristics. Although varied, AI among FSW is generally common, inconsistently protected with condoms and practiced sufficiently frequently to contribute substantially to HIV acquisition in ...

The RMS value of the entire current is found by summing the RMS value of each harmonic current. Given a 60-Hz waveform, this means a 2nd harmonic frequency would be 120 Hz (60 Hz x 2 = 120 Hz) and the 3rd, 4th, and 5th harmonic frequencies would be 180 Hz, 240 Hz, and 300 Hz...
