An Automatic Bearing Fault Diagnosis Method Based on Characteristics Frequency Ratio
Sensors, 2020 Bearing is a key component of satellite inertia actuators such as moment wheel assemblies (MWAs) and control moment gyros (CMGs), and its operating state is directly related to the performance and service life of satellites.

Seminars in Musculoskeletal Radiology, 2015 The rotator interval is an anatomically complex region of the shoulder joint that is difficult to evaluate on clinical examination and by imaging. Abnormalities of its components may contribute to instability, shoulder stiffness, and pain and are challenging to diagnose and treat.

Enhanced Vertical Inhomogeneity in Turbulent Rotating Convection [PDF]
, 2008 In this Letter we report experimental evidence that rotation enhances vertical inhomogeneity in turbulent convection, in spite of the increased columnar flow ordering under rotation.

Rotational splittings for slow to moderate rotators: Latitudinal dependency or higher order effects in \Omega? [PDF]
, 2012 Information about the rotation rate is contained in the low frequency part of power spectra, where signatures of nonuniform surface rotation are expected, as well as in the frequency splittings induced by the internal rotation rate. We wish to figure out
