We investigate the impact of different numbers of positive and negative examples on machine learning for sapphire crystals defects prediction.We obtain the models of crystal growth parameters influence on the sapphire crystal growth.For example, these models allow predicting the defects that occur due to local overcooling of crucible walls in the t
The literature reports that there was a significant difference in the medical impact of the coronavirus disease (COVID-19) pandemic between European and East Asian countries; specifically, the mortality rate of COVID-19 in Europe was significantly higher than that in East Asia.Considering such a difference, our narrative review aimed to compare the
In case pressurized water or vapor leaks from a failed heat transfer tube in a steam generator of a sodium-cooled fast reactor, a high-velocity, high-temperature, and corrosive jet with sodium-water chemical reaction may cause tube failure propagation.In this study, a numerical analysis method to predict the occurrence of tube Siemens iQ500 MB535A0
