active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. this paper proposes a control scheme based on the instantaneous active and reactive power. the inverter of this active filter is a three-phase, two-level converter. space vector technique is used as modulators and pattern genera...

conclusions the administration of dextrose saline was associated with a shortened active phase and second stage of labor in vaginally delivered nulliparous women. results of 174 objects enrolled, 150 women delivered vaginally and completed the study. there was a significant difference in the duration of active phase between the groups (ns: 270.20 ± 13.37 minutes; d5ns: 206.67 ± 11.72 minutes) (...

comparing the post partum hemorrhage based on hb and hct in women admitted in latent and active phase of labor    naghizadeh s [1] , sehati shafaei f [2] *, ghojazadeh m 3     received: 16 jul , 2013 accepted: 5 sep , 2013  abstract   background & aims : attention to admission time of women for delivery can prevent the majority of mother and neonate complications. one of the labor complications...

In recent years, active filters have been considered and developed for elimation of harmonics in power networks. Comparing with passive, they are smaller and have better compensating characteristics and resistance to line distortions. In this paper, a novel idea based on adaptive filter theory in presented to develop an active filter to eliminate the distortions of an arbitrary signal. Using th...

Background: Fetal male gender may affect the progression of labor and could be a risk factor for labor arrest. This study was conducted to evaluate the effect of fetus gender on labor curve.    Methods: In this cohort study, 1550 singleton term pregnant women in labor phase (either spontaneous or by induction) were enrolled. Results of regular cervical examination, dilation, length o...
