Advanced Photonics Research, Volume 6, Issue 12, December 2025.Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 800-815, December 2025.The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.

Hydrodynamic Removal of Sediments in Open Irrigation Channel
Modern Agriculture, Volume 3, Issue 2, December 2025.The experimental study investigated the hydraulic behaviour of particle transport in an irrigation channel equipped with submerged longitudinal structures designed to reduce the effective cross‐sectional area. The findings demonstrate that the placement of parallel barriers along the flow axis generates localized acceleration and turbulence, which ...

Application of Electro-Hydraulic Servo Systems to Hot Strip Down Coilers
International Journal of Automation Technology, 2012 Many kinds of electro-hydraulic servo systems have been applied to rolling mills, such as hot strip mills, cold strip mills, and seamless tube mills, for their quick response, high power, and high positioning accuracy. However, when an electro-hydraulic servo system is applied to a hot strip down coiler, it is found that the controlled object has low ...
