Geometric machining errors in the blade profile and variable operating conditions extreme environment are primary factors leading to uncertainties pump performance. This paper presents an analysis of fuel centrifugal pumps by modeling geometry uncertainty based on Karhunen–Loève (KL) expansion using a polynomial chaos (PCE) model. First, geometric is described KL three sections stochastic simulation performed. Then, PCE surrogate model trained least angle regression method validated...
In order to evaluate the efficacy of resecting extramedullary subdural tumors, located in thoracic spinal canal, via muscle-pedicle open-door laminoplasty approach, clinical data fifteen patients with tumors admitted Department Spinal Surgery Affiliated Hospital Qingdao University from December 2018 June 2021 were analyzed retrospectively. All received surgical treatment remove approach. The patient was recorded. Japanese Orthopedic Association (JOA) score, kyphosis angle standing position...
