Abstract The presence of defects, such as pores, in materials processed using additive manufacturing represents a challenge during the manufacturing of many engineering components.Recently, ultrasonic vibration-assisted (UV-A) directed energy deposition (DED) has been shown to reduce porosity, promote grain refinement, and enhance mechanical perfor
Passive rewildening of forest ecosystems is commonly used for rehabilitating degraded habitats closer to their natural origin in addition to costly active restoration measures.However, it is not clear if passive processes are effective and how long the recovery of main ecosystem properties takes.We investigate the recovery of forest soil and tree s
High-precision forecasting of short-term wind cubs foam finger power (WP) is integral for wind farms, the safe dispatch of power systems, and the stable operation of the power grid.Currently, the data related to the operation and maintenance of wind farms mainly comes from the Supervisory Control and Data Acquisition (SCADA) systems, with certain i
