Remaining Service Life (RSL ) Assessment of Engine Oil in Rock Excavators

Failure Probability and Remaining Life Assessment of Reheater Tubes

In this study, a real and significant industrial problem in a steam power plant was investigated. Reheater tubes in boilers are under the creep and the fireside corrosion mechanism that cause some of them to fail. Since the estimation of probability of failure (PoF) and remaining life (RL) is expensive and time consuming in the deterministic methods, in this work they were evaluated using struc...

securitization of mortality risks in life annuities

insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...

Thermo-Mechanical Fatigue Life Assessment of a Diesel Engine Piston

Remaining Useful Life Estimation In the Presence of Given Shocks

In a system, prediction of remaining useful lifetime (RUL) of servicing before reaching to a specified breakdown threshold is a very important practical issue, and research in this field is still regarded as an appreciated research gap. Operational environment of an equipment is not constant and changes regarding to stresses and shocks. These random environmental factors accelerate system deter...

In-line Oil Debris Monitor for Aircraft Engine Condition Assessment

Dimensional Discrepancies Overrolling of Debris Corrosion Other Fatigue Absrrucr-The development of an in-line, full flow oil debris sensor for aircraft engine condition assessment is described. First used on the F22 fighter, this sensor is the only “ all-metals” debris detector in production. The sensor is based on an inductive measurement technique which enables the system to detect, count an...
