IET Image Processing, Volume 20, Issue 1, January/December 2026.Existing methods often struggle to balance accuracy and robustness against complex interference such as noise and artefacts inherent in industrial CT imaging. To overcome these limitations, we propose an innovative framework named MultiBlock‐SwinUnet. This architecture is designed to enhance feature extraction for different categories of concrete and ...

Experimental Study of a Novel Type Joint Used in Precast Reinforced Concrete Frame Under Reversals
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Prefabricated components are an integral part of the prefabricated construction. One of the main challenges in seismic regions is developing constructible connections between prefabricated components that can withstand inelastic cyclic deformations. This study introduces a novel type of joint designed to connect prefabricated concrete columns and beams
