Microstructure reconstruction via artificial neural networks: a combination of causal and non-causal approach
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)We investigate the applicability of artificial neural networks (ANNs) in reconstructing a sample image of a sponge-like microstructure. We propose to reconstruct the image by predicting the phase of the current pixel based ... -
Modelling of fission gas release in UO2 doped fuel using transuranus code
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The expected benefits from Cr-doped fuel are improved retention of fission gases within the pellets due to its large grain size. To demonstrate this, several experiments have been carried out by Halden reactor and Studsvik. ... -
