THANK YOU. Web6. It depends what you mean by "normalised"; it also depends on your software's choices. "Normalised" is a word often avoided by statistical people, because it is ambiguous as between (a) scaled or standardized (e.g. to total 1 or to mean 0 and SD 1) and (b) transformed (approximately) to normality, meaning normal or Gaussian distribution. portable buildings in pensacola

http://www.fit.vutbr.cz/~ihubeika/ISS/lect/diskretni_en.pdf WebNormalized Frequency The normalized frequency, or V number, is a parameter used in optical fibers. The normalized frequency is proportional to the radius of the fiber divided by the wavelength times the square root of the difference of the squares of the maximum refractive index of the core and the refractive index of the homogeneous cladding.
