A health monitoring metho system identification techniques, which all detection of the presence of abnormal ther evaluation of solder layer health. The therm for thermal characterization and it can be u system identification technique. This can e temperature being accurately estimated und degraded heat dissipation path. A fast…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
