Upper bound element technique (UBET) is used to simulate axisymmetric forging and to determine the optimum intermediate shapes using backward simulation.
The upper bound element technique (UBET) is used to determine the optimum intermediate shape for profile ring rolling using backward simulation.
The best model fit was found by using backward stepwise deletion of insignificant terms.
From this general model, we eliminated the nonsignificant terms by using backward stepwise regression.
The governing equations were solved numerically by using backward finite difference method.
Stackelberg games can be solved by using backward induction.
By using backward elimination, we eliminated all variables that were not statistically significant at p<0.05.
A P-value <0.05 was considered statistically significant by using backward-LR method.
We evaluated confounding by these covariates using backward selection with a 10% change in estimate criterion.
Predictors of response were identified by logistic regression using backward elimination.
