Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.Abstract Off‐stream reservoirs are artificial water storage structures that increase the flood risk of an area. In some places, related risk reduction plans are based on a risk classification of these structures, which follows local water resource management regulations. These classification methods typically follow deterministic qualitative guidelines

Coarse‐Grained Ore Distribution on Conveyor Belts With TRCU Neural Networks
IET Image Processing, Volume 19, Issue 1, January/December 2025.(1) The method can be used as technical support and the basis for subsequent real‐time particle size detection in the beneficiation process. (2) The proposed model combines Transformer and residual blocks with the CBAM attention mechanism in the encoder‐decoder. (3) The proposed model can effectively partition the ore particles of different grain sizes.
