Bayesian Architecture for Predictive Monitoring of Unbalance Faults in a Turbine Rotor-Bearing System.

Unbalance faults are among the common causes of interruptions and unexpected failures in rotary systems. Therefore, monitoring unbalance faults is essential for predictive maintenance. While conventional time-invariant mathematical models can assess the impact of these faults, they often rely on proper assumptions of system factors like bearing stiffness and damping characteristics.

Rest cannot always recover the dynamic properties of fatigue-loaded intervertebral disc.

Study Design: An in vitro biomechanical study using adolescent porcine discs.

Objective: To find the effect of fatigue loading and rest on the dynamic properties of healthy intervertebral disc.

Summary Of Background Data: The fatigue loading is a risk factor for low back pain.
