Degradation Prediction of Proton‐Exchange Membrane Fuel Cell Tested Under Static and Quasi‐Dynamic Operating Conditions

Fuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT The viability and extended lifetime of proton‐exchange membrane (PEM) fuel cells are essential to enable hydrogen electric aviation. Their reliability, that is, the ability to maintain stable performance over long operational periods under varying environmental and load conditions, is a critical factor for their adoption in aviation systems ...

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

Pest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Aircraft lifecycle cost-benefit analysis of PHM systems

, 2010
The use of prognostics and health management (PHM) systems can improve operational reliability by reducing delays and cancellations caused by unscheduled maintenance events and no-fault-founds (NFFs).

Analytical health indices : towards reliability-informed deep learning for PHM

Deep learning has demonstrated significant potential for prognostics in complex systems (Fink et al., 2020). Recent advances in physics-informed machine learning have integrated physics-of-failure principles within data-driven models (AriasChao, Kulkarni,

TOWARDS DEVELOPING A NOVEL FRAMEWORK FOR PRACTICAL PHM: A SEQUENTIAL DECISION PROBLEM SOLVED BY REINFORCEMENT LEARNING AND ARTIFICIAL NEURAL NETWORKS

International Journal of Prognostics and Health Management, 2019
The heart of prognostics and health management (PHM) is to predict the equipment degradation evolution and, thus, its Remaining Useful Life (RUL). These predictions drive the decisions on the equipment Operation and Maintenance (O&M), and these in turn ...
