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 ...

Enhanced Stability and Liquefaction Resistance of Earth Dams With a Proposed Method of Geosynthetic Reinforcements

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This study evaluates the static and seismic stability of the Narasimharaya Sagar (Gorukallu Balancing Reservoir) earthen dam, located in India’s seismically active Zone II. Using GeoStudio software, seepage, slope stability, and liquefaction analyses were conducted to assess the dam’s performance under static and dynamic conditions.

Causes of Tensile Strain of Asphalt Concrete Core Wall of Rockfill Dam in High‐Cold Area During Construction

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Asphalt concrete core rockfill dams, favored for their superior impermeability and adaptable deformation capacity (effectively accommodating uneven settlement), have been gaining increasing attention in Chinese engineering practice. However, ensuring safety during high‐temperature paving and subsequent cooling remains crucial.

Feedback Analysis of Deformation Modulus for an Extra‐High Arch Dam With Dam Height of 300 m Level

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Deformation is a critical indicator for safety monitoring of arch dams in operation; comparing measured deformation values with calculated ones is a common approach to assess dam behavior. However, deformation calculated based on design deformation parameters often significantly differs from measured values, especially for extra‐high arch dams; to ...
