A Publication, Prognostics CoE Publications - 11 years, 8 months ago

Shared By: Miryam Strautkalns

When we address safety in a book on the business case for IVHM, the question arises whether safety isn’t inherently in conflict with the need ...

Model-based Prognostics with Fixed-lag Particle Filters

A Publication, Prognostics CoE Publications - 12 years, 9 months ago

Shared By: Matthew Daigle

Model-based prognostics exploits domain knowledge of the system, its components, and how they fail by casting the underlying physical phenomena in a physics-based model that ...

Model-based Prognostics under Limited Sensing

A Publication, Prognostics CoE Publications - 12 years, 9 months ago

Shared By: Matthew Daigle

Prognostics is crucial to providing reliable condition-based maintenance decisions. To obtain accurate predictions of component life, a variety of sensors are often needed. However, it ...

A Publication, Prognostics CoE Publications - 12 years, 9 months ago

Shared By: Matthew Daigle

Model-based prognostics captures system knowledge in the form of physics-based models of components, and how they fail, in order to obtain accurate predictions of end ...

Prognostics for Ground Support Systems: Case Study on Pneumatic Valves

A Publication, Prognostics CoE Publications - 12 years, 9 months ago

Shared By: Matthew Daigle

Prognostics technologies determine the health (or damage) state of a component or subsystem, and make end of life (EOL) and remaining useful life (RUL) predictions. ...

A Model-based Prognostics Approach Applied to Pneumatic Valves

A Publication, Prognostics CoE Publications - 12 years, 9 months ago

Shared By: Matthew Daigle

Within the area of systems health management, the task of prognostics centers on predicting when components will fail. Model-based prognostics exploits domain knowledge of the ...
