    Absolute Error
AI Thread Summary
The discussion centers on clarifying the concept of absolute error in machine measurements, specifically addressing a stated error of 1.3%. Absolute error is defined as the difference between theoretical and measured values. Participants seek to understand how the 1.3% error is calculated and its relevance to the overall measurement accuracy. Additional context and examples of theoretical versus measured values are requested to enhance understanding. The conversation aims to demystify the implications of this percentage in practical applications.

In writing up on errors and knowing the error of the machine used (as told by the technician) as being 1.3%
where I have a table of theoretical and measured values,
The absolute error the difference between the theoretical and measured value, but where does the 1.3% error come into play?

And what type of error is it?

Hello Steve, :welcome:

Could you give a bit more context ? What's this about ? And perhaps a few examples of measured and theoretical values ?

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
