In this paper, a new optimal robust control design approach is proposed for the task of spacecraft rendezvous such that both the stabilization and optimal performance are achieved. An approximate closed-form solution to the nonlinear optimal control problem is obtained by employing the θ-D technique, which is derived based on an approximate solution to the(More)
The new type of piezoelectric vibration accelerometer was studied, which sensitive element is cymbal piezocomposite transducer with 2-(0)-2 connectivity rather than conventional piezoelectric ceramic. The nonlinearity property of output voltage of this new piezoelectric vibration accelerometer was investigated. The measurement circuit was designed. Using(More)

BACKGROUND By changing the paradigm of neonatal intensive care and integrating parents into the care team, the 'family integrated care' (FICare) model developed in Canada ensures that infants receive more consistent care and parents are better able to care for their infants within the neonatal intensive care unit (NICU) and at home. However, Chinese health(More)
The aim of the present study was to analyze the changes of plasma and urinary prostaglandin E2 (PGE2) levels in preterm infants with symptomatic patent ductus arteriosus (sPDA) treated with oral ibuprofen and acetaminophen. A total of 87 preterm infants with sPDA admitted to the Neonatal Ward of the Affiliated Xuzhou Hospital of Medical College of Southeast(More)
