Analysis of the influence of electrical damage in field magnetizing coil on synchronous round-rotor motor vibration

Relevance.Powerful high-voltage synchronous motors with STD and STDP round rotor series are the main elements of oil gathering system and maintaining reservoir pressure.This fact increases the operational reliability demands.Vibration condition is one of the key parameters controlled in operation.The vibration sources are mechanical and electrical.

A metal artifact reduction algorithm in CT using multiple prior images by recursive active contour segmentation.

We propose a novel metal artifact reduction (MAR) algorithm for CT images that completes a corrupted sinogram along the metal trace region.When metal implants are located inside a field of view, they create a barrier to the transmitted X-ray beam due to the high attenuation of metals, which significantly degrades the image quality.To fill in the me
