Excavator’s main tasks include digging, trenching, and ground leveling at construction sites, as well work efficiency safety can be improved by using an autonomous excavator. A prerequisite step to achieving excavation is obtain a sound perception of the surrounding ground. For this, LiDAR sensor has been widely used scan environment. However, point cloud generated not ideal for surface reconst...

Abstract. Peatlands are a significant global carbon (C) store, which can be compromised by drainage and afforestation. Quantifying the rate of C loss from peat soils under forestry is challenging, as soil CO2 efflux includes both produced heterotrophic decomposition tree roots associated fungal networks (autotrophic respiration). We experimentally terminated autotrophic below-ground respiration...

The anchoring and hooking of ships, bedrock friction biological corrosion threaten the safety stability submarine cables. A hydraulic jet cable laying machine manages to bury cables deep into seabed, effectively reduces occurrence external damage This uses a system realize trenching on seabed. However, has complicated operation high power consumption with requirements mother ship, it is not yet...

A hyphenated optical-electrochemical technique and image analysis protocol is used to quantify global local (intermetallic) corrosion process kinetics. Our findings reveal an early stage (< 60 s) composition-dependent hierarchical activation of all IMs that can be attributed IM dealloying. This followed by trenching initiated at matrix locations adjacent regions the previously dealloyed, which ...
