Artificial Intelligence for Engineering, EarlyView.An ultra‐lightweight semantic segmentation network RailNet with only 0.905 M parameters is proposed for rail surface defect detection. Combined with a CDBM image enhancement and GAN‐based data augmentation, RailNet achieves superior segmentation accuracy and real‐time speed on edge devices.

Effect of noise events on inhabitants' reactions to railway noise.
Journal of the Acoustical Society of Japan (E), 1989 The effect of noise events of railway noise has been found in earlier researches. But this is inconclusive problems. The number effect of ordinary railway noise in Tokyo was examined for sixteen different reactions. Analyses were conducted for individual and grouped data of Likert's scales and highly disturbed responses.
