This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control (SMC) approach in stationary reference frame, without the requirement of synchronous coordinate...

role of labor induction has increased in the last decade due to the ‎early detection of fetal jeopardy. although very useful, oxytocin alone is not always successful for induction of ‎labor. in a randomized clinical ‎trial we compared vaginal dinoprostone plus oxytocin with oxytocin alone for ‎induction of labor in 91 ‎pregnant women at 40 weeks or greater gestation with bishop scores ≤ 4. fort...
