Comparative spatiotemporal water quality dynamics in Tappan Lake using various Water Quality Indices

Freshwater ecosystems, such as Lakes and Reservoirs, have been facing escalating anthropogenic activities across the world, leading to the decline of lake water quality. Consequently, monitoring and evaluation of Lake water quality conditions are essential to ensure a sustainable...

Investigation of soil arching evolution in piled embankments with three-dimensional trapdoor tests

This study focused on the mobilisation and degradation of three-dimensional soil arching by adopting a matrix trapdoor test device with 144 individually and electrically controlled movable plates to simulate unreinforced piled embankments at different coverage ratios and fill hei...

Autonomous Isolated Power Conversion Architecture for Lunar and Mars Resource Extraction Robots

Autonomous robotic systems designed for extraterrestrial in situ resource utilization (ISRU) will play a central role in enabling a sustained human presence on the Moon and Mars. These robots are expected to perform tasks such as regolith excavation, water extraction, oxygen prod...
