I have a question concerning a career move. I have a chance to switch from the nuclear industry to the aerospace industry. I am just wondering if this is smart or not. Based on the current events taking place in the world and the concern and threat of individuals acquiring and transporting...

Could someone explain undulation per revolution? I would prefer to have a mathematical function defining it also if possible. Can any explain ONE also? .

Poor Terminology Hurkyl I am sorry for the incorrect usage of the terminology mean and variance. The statement should have read the mean and variance can be estimated from the sample mean and variance. That was my intent of this posting was to have things like that brought to my attention...

Thoughts No- The sample mean and variance are only estimates of the distributions mean and variance.

The following is crude derivation demonstrating how a distribution such as the normal distribution is simply one distribution that stems from a family of similar distributions. I originally was going to post this in the new Independent Research forum but the moderator thought it was...

It hits home My current employer was scheduled this year to start building a prototype manufacturing facility for this fuel. It was high hopes for us.

Education I think the first question I would ask my self is. What level of education I would be willing to pursue? Speaking from experience your decision is subject to change without notice over time.

Hurkyl I see your point but either method reduces the unnormalized density function the same proportion of area to equal 1. If this occurs why doesn’t it preserve proportionality? In sense when you multiple by the reciprocal of area the functions height it is reduced by some quantity at the...

Signal Decomposition If you just look at the signals spectrum it will hard to distinguish between harmonics from the noise and signal. Signals can be decomposed into typical two components. They are others but they are immaterial to this purpose. You can smooth a signal by using a moving...

Data Points I would try to obtain more data points if possible (50 minimum). Especially since you are trying to analyze noise. I would also suggest taking the magnitude of the Fourier components (Periodogram) instead of using a FFT. A(f) = \frac{2}{N} \cdot \sum\limits_{t = 0}^{n - 1} {x_t...

Method Meaning the PDF (1st or 2nd) that contours to the distribution of my data the best.

Intensity I is the intensity.
