To mitigate the adverse effects of binders in the anode of microbial fuel cells (MFCs) and to enhance the performance of WO 3 anodes, the WO 3-X /CC, serving as a high-performance anode for MFCs, was developed using magnetron sputtering to apply tungsten oxide onto carbon cloth....

FuzzyCS-Proto: fuzzy client selection with class-wise prototype learning for federated ship underwater structural surface condition classification

Underwater structural inspection is essential for ship maintenance and marine infrastructure management, but practical inspection data are often distributed across different vessels, ports, inspection platforms and sensing devices. Direct centralized training may be limited by da...

Parametric study of injection strategy and two injector layouts for a large low-speed marine HPDI methanol engine

Methanol, as a promising green alternative fuel in marine engines, suffers from the challenge of balancing thermal efficiency and NOx emissions when applied to large low-speed marine high pressure direct injection (HPDI) engines. This study aims to investigate the influence of in...
