Szukana fraza: [Abstract = "The article presents research results on predicting the deviations for two different timescales, UTC\(PL\) and UTC\(NPL\) by means of GMDH type Neural Network. UTC\(PL\) timescale was realized by commercial caesium atomic clock. The UTC\(NPL\) timescale, on the other hand, is based on an active hydrogen maser, additionally supervised by the primary frequency standard in the form of a caesium fountain."]
