Health Monitoring on the Spacecraft Bearings in High-Speed Rotating Systems by Using the Clustering Fusion of Normal Acoustic Parameters

open access: yesApplied Sciences, 2019
The rolling bearings in moment wheel assemblies (MWAs) or control moment gyros (CMGs) are not only the core components in spacecrafts but also prone to failure.

A Fault Diagnosis Method for Satellite Flywheel Bearings Based on 3D Correlation Dimension Clustering Technology

open access: yesIEEE Access, 2018
Flywheel bearing is a key mechanical part of a satellite. Its health plays an important role in the fatigue life of the satellite. However, it is rather difficult to diagnose the health state of the bearings due to the complex satellite system.

Rotational Modes in A Uniformly Rotating Star [PDF]

open access: yesInternational Astronomical Union Colloquium, 1980
AbstractThe linear adiabatic oscillations of a uniformly rotating star are examined with respect to a co-rotating frame of reference. It is shown that time-independent displacement fields are allowed and can be represented as toroidal fields. The time-dependent oscillation modes are governed by a system of differential equations of the fourth order in ...

The Saxmundham rotation experiments: rotation II, 1899–1952

open access: yes, 1966
The rotation II experiment at Saxmundham, which ran from 1899-1952, was designed to show how limited quantities of FYM, N and P could best be allocated to the crops of a four-course rotation; there were also tests of additional quantities of N and P ...

Genome scan of Diabrotica virgifera virgifera for genetic variation associated with crop rotation tolerance [PDF]

open access: yes, 2007
Crop rotation has been a valuable technique for control of Diabrotica virgifera virgifera for almost a century. However, during the last two decades, crop rotation has ceased to be effective in an expanding area of the US corn belt.

How Good are Orthopaedic Surgeons at Interpreting ECGs?

open access: yesJournal of Orthopaedics, Trauma and Rehabilitation, 2010
This study is to find out how good orthopaedic surgeons are at interpreting electrocardiograms and to compare the results between surgical specialties with physicians. It showed that surgeons were considerably weaker than physicians in this aspect.
