Prediction of Pollutant Emissions from a Low-Speed Marine Engine Based on Harris Hawks Optimization and Lightgbm
Published 2024-11-01“…The results show that changes in engine control parameters have significant influences on NOx and soot emissions from the engine, which can serve as the basis for the selection of the LGB model features; the LGB model was able to accurately predict pollutant concentrations from the engine with much higher accuracy than a single decision tree (DT) model; combining with HHO, the predictive ability of the LGB model was significantly improved, such as for the validation set prediction results, the mean absolute error (MAE) was reduced by about 20%, the mean squared error (MSE) was reduced by about 30%, and the coefficient of determination (R<sup>2</sup>) was increased by about 0.005; and the importance analysis of the model features indicated that the combustion condition of the fuel was highly correlated with the generation of the pollutants, and the fuel injection phases can be adjusted in practice to achieve highly efficient and low-emission processes of combustion. …”

Study on the crack self-healing performance of nano-micro silica modified hydrogel
Published 2025-08-01“…This enabled the cracked samples to have a lower gas permeability coefficient, especially under 0.3 mm wide cracks, showing a more explicit healing effect; (2) For 0.1 mm narrow cracks, hydrogels already exhibited good crack healing effects at a low dosage of 1 %, while for 0.3 mm wide cracks, hydrogels only demonstrated a higher healing efficiency at a high dosage of 3 %; (3) Either under wide crack or narrow crack conditions, the gas permeability of cracked samples containing larger initial particle size hydrogels was significantly lower than that of smaller particle size samples, indicating that hydrogel with larger particle size has better crack healing ability.…”
