Dust mitigation by the application of treated sewage effluent (TSE) in Iran

open access: yesScientific Reports, 2022
Considering the presence of 274 dusty days in 2021 in Zabol city, Iran, the present study aimed to evaluate the feasibility of using treated sewage effluent (TSE) for dust mitigation with natural methods of increasing land cover. Hence, first of all, the

Random survival forests [PDF]

open access: yes, 2008
We introduce random survival forests, a random forests method for the analysis of right-censored survival data. New survival splitting rules for growing survival trees are introduced, as is a new missing data algorithm for imputing missing data.
