Xue Zhao et al.
Based on statistical data from 2005 to 2019, we used the back propagation (BP) neural network model to predict the production amount of plastic waste in Chengdu. In addition to the amount of waste produced we wanted to achieve an understand...
Field-based assessment of the design of lysimeters for landfill final cover seepage control [0.03%]

Thierry Kahale et al.
Lysimeters are considered the most appropriate instrument for assessing percolations rates through landfill final covers. Their design, however, must take into consideration the unsaturated nature of water seepage, otherwise they may act as...
Experimental study of a full-scale hexagonal wet electrostatic precipitator for collection of black carbon and particulate matter generated by a marine diesel engine [0.03%]
船用柴油机排放黑碳和颗粒物六角形湿式电除尘器满规模实验研究

Nick Høy Hansen
Wet electrostatic precipitators have demonstrated a robust capability for removal of particulate matter by minimizing back corona and particle re-entrainment of fine particles. The absence of studies investigating the removal of black carbo...
Development, evaluation, and implementation of building downwash and plume rise enhancements in AERMOD [0.03%]
AERMOD中建筑物下洗和烟羽扩散高度改进的研发、评估及应用研究
