An innovative fault analysis framework to enhance building operations
… modeling and the fault mode and effect analysis (FMEA) applications to the building technology with a conclusion that few FMEA studies were applied in the building Heating, Ventilation, and Air-Conditioning (HVAC) systems. This study aims to fill this gap by investigating fault impacts through an …

A systems-based analysis method for safety design in rocket testing controllers
… a comparable "ascent phase" analysis using FMEA. The STPA results are the same or meet a similar intent to those resolved in the FMEA with not gaps between the two methods. The recommended mitigation and constraints resulting from STPA are arguably more intuitive than those of the FMEA.

Dynamic safety assessment of FPGA-based safety critical systems with applications in nuclear power generation
… Initially, a Failure Modes and Effects Analysis (FMEA) was performed to ascertain the potential failure modes that could affect FPGA-based systems, and that FMEA data was used to create and FPGA failure modes taxonomy. Using that FMEA data to provide information for fault injection, DFM was …
