A Study of Mathematical Modeling of Remaining Useful Life, Assessment, and Prognostics & Health Management (PHM)
… signal and its application in RUL assessment and PHM. Monotonicity of the degradation signal with respect to model error is explored in a simulation using Matlab. The decomposition of observation data for online degradation analysis is also studied. Furthermore, a concept of online RUL assessment …

Systems Engineering Processes for the Acquisition of Prognostic and Health Management Systems
Prognostic and Health Management (PHM) systems often experience delayed fielding and lengthened maturation cycles due to their relative immaturity and the fact that they are regarded as non-flight critical systems. The national fiscal crisis and rising debt of the U.S. have each placed increased …

Heterologous production of recombinant peptidylglycine α-amidating monooxygenase for the production of biosimilar α-amidated peptides
… peptidylglycine α-hydroxylating monooxygenase (PHM) and peptidylglycine αamidating lyase (PAL). The cost and limited quantities of the commercial PAM variants available have necessitated research into low cost, scalable quantities of PAM and peptide amidation to enable inexpensive biological …

Development of an approach to incorporate proportional hazard modelling into a risk-based inspection methodology for an optimal inspection policy
… of incorporating the proportional hazard model (PHM), which is a statistical procedure to estimate the risk of failure for a component subject to condition monitoring, into the risk-based inspection (RBI) methodology so that the PoF estimation can be enhanced to optimize inspection policies. To …
