Active magnetic bearings are complex mechatronic systems that consist of mechanical, electrical, and software parts, unlike classical rolling bearings. Given the complexity this type system, fault detection is a critical process. This paper presents new easy way to detect faults based on use dictionary machine learning. The was built starting from signatures consisting images obtained signals a...

background: according to recent studies comparing magnetic resonance enterography (mre) with ileocolonoscopy for assessing inflammation of small bowel and colonic segments in adults with active crohn’s disease (cd), we aimed to compare the accuracy of these two diagnostic methods in iranian population. method: during 2013-2014 a follow-up study was done on 30 patients with active cd ina gastroe...

Active magnetic bearings are increasingly being utilized in rotating machinery applications as an alternative to the conventional rolling-element and fluid-film bearing types. In this paper three control schemes for a large air-gap magnetic bearing system are described. In the large air-gap situation, the magnetic bearing system operates in highly nonlinear regimes .The non-linearity in this sy...
