The three sigma rule - Pukelsheim - 1994 () Citation Context ...ue such as √Σε ii = 2◦ C would be appropriate, perhaps representing his view that Pr ( |ε ∗ i | ≤ 6 ◦ C ) ≥ 95%, by a statistical rule of thumb for unimodal distributions known as the 3-Sigma ...
As a rule of thumb, we counted as a valid motif when there were no fourfold vertex configurations in any of the two surfaces. We applied this consensus to all the images from actual tissues. Once the valid motifs were selected, we measured four properties related to epithelial architecture, ...
One of the most important EMC issues is keeping the product's internal frequencies internal, so they don't pollute the radio spectrum externally. The half-wave resonance of slot antenna (expressed in the above rule of thumb: SE=20 log(2 d)) using the relationship v=fλ (where v is ...
