  • There is an adjustable feedback from the main valve to the pilot valve to adjust the ratio of main valve to pilot valve movement. By changing the amount the main valve moves for a given movement of the pilot valve, the relative speed of the servomotors is changed. This is independent of the setting for wicket gate travel rate. The main valve normally doesn’t move far enough to contact the stop nuts during a load change. The feedback acts on the pilot valve bushing to close off the pilot valve ports to stop the flow of oil...

  • lasso estimates can be obtained at the same computational cost as that of an ordinary least squares estimation Hastie et al. (òýýÀ). Further, the lasso estimator remains numerically feasible for dimensions m that are much higher than the sample size n. Zou and Hastie (òýý ) introduced a hybrid PLS regression with the so called elastic net penalty dened as "Ppj =Ô(ò ( j + Ô −)SjS). Here the penalty function is a linear combination of the ridge regression penalty function and lasso penalty function. A dišerent type of PLS, called garotte is due to Breiman (ÔÀÀç).
