They were described as "identical as two cigarettes in a pack" but could be distinguished because "Mary smokes, Kathryn doesn't".
Then, after scrambling the signal, each different channel can be distinguished because each one uses a different OVSF spreading code.
In this way, the differences between charge and discharge cannot be distinguished, because they both occur in one cycle of the alternating current.
Neotectonic results were analyzed, and it was found that this plate could be distinguished because of quaternary faults observed in Landsat images.
Under the SEM EDS, the white and the light blue layers cannot be distinguished because they have the same elemental composition (Ti, Ba and S).
With the water cooling method, the coflow and counterflow methods did not need to be distinguished because of their small difference, but they should be distinguished for the air cooling method.
While anchorage using FRP strips may seem similar to transverse wrapping, the behavior can be distinguished because the strips do not provide a clamping effect to the FRP below.
In this context, C3 and C4 plants are distinguished because of significant differences in the way of their carbon-fixation: C4 plants (e.g. corn and sugar cane) are able to fix more atmospheric carbon dioxide at high temperatures than C3 plants (e.g. wheat and barley).
However, the contribution of Cu and (Ti, Mo) C to precipitation strengthening could not be distinguished because quantification of precipitation hardening is a challenging subject as it demands combined knowledge of precipitation strengthening mechanism and reliable measurement of precipitates size and volume fraction.
