NO and NO 2 continuously recycle in the lower atmosphere through a complex series of reactions involving NO, VOCs, NO 2 , and O 3 . Therefore, the NO 2 /NO x ratio can be utilized in dispersion models as an important substitute to understand the fate of NO and NO 2 in the atmosphere. In this work, random forest regression was used to analyze the significance of meteorological parameters that affect the prediction of the NO 2 /...

In this study, the elastic characteristics of reservoir rocks and their relationship to porosity and pore fluid were predicted using the fluid substitution method in combination with machine learning techniques. We first discarded the data at gas points to remove the erroneous effect of gas on the prediction process of Poisson’s ratio using the three proposed machine learning models. Then, the prediction was carried out after...
