Stent Reliability and Maintenance: Integrating Probabilistic and Physics-of-Failure Models
The rapid advancement of biomedical implant devices has raised new challenges to the failure analysis and reliability study of such new devices. More than one million stents are implanted in human arteries each year. These devices are subject to a wide range of stress due to biological and …

Well Integrity Mapping Using Hybrid Model Based on Physics of Failure and Data-Driven Methods
Presence of H2S in high pressure and high temperature wells with pressures greater than 15,000 psi or temperatures of 350 °F can lead to strength reduction of casing strings and advance the time to failure. Casing strings also get damaged during drilling. The objective of this study is to develop a …

Spatio-temporal probabilistic methodology to estimate location-specific loss-of-coolant accident frequencies for risk-informed analysis of nuclear power plants
… Regulatory Commission (NRC) has promoted the use of Probabilistic Risk Assessment (PRA) in nuclear regulatory activities. Since loss-of-coolant accidents (LOCAs) are critical initiating events for many PRA applications, the NRC has taken steps towards the quantification of LOCA frequencies for use …

Prognostic modelling for residual useful life prediction
In the context of this thesis, prognosis aims at predicting the residual useful life ofcomponents using condition monitoring information. It enables a projection ofcomponent condition from the past and present into the future, providing significantassistance to maintenance decision making and asset …

Conquering the challenge of reliability: text mining to map trends in reliability engineering literature
Reliability engineering faces many of the same challenges in 2023 that it did at its inception in the 1950s. The fundamental issue remains uncertainty in system representation, specifically related to performance model structure and parametrization. Details of a design are unavailable early in the …
