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.

Marine Fish Passage—Underappreciated Threats to Connectivity Within the Marine Environment
Marine Ecology, Volume 46, Issue 1, January 2025.ABSTRACT Habitat fragmentation is a major threat to aquatic biodiversity loss. However, much of the focus is on the connectivity of freshwaters, with much less attention given to marine ecosystems. We contend that coastal infrastructure including bridges, causeways, tidal turbines, land infilling and harbours, wharfs, quays, piers and docks have ...

A simple permanent deformation model of rockfill materials
, 2018 Existing experimental results have shown that using a semi-log linear relationship between the permanent volumetric strain and cyclic number underestimates the volumetric deformation of rockfill materials with a large cyclic number, and that the error ...
