In this study, the effect of randomness of blowing ratio on film cooling performance is investigated by combining direct numerical simulations with a stochastic collocation approach. The geometry includes a 35-deg inclined jet with a plenum attached to it. The blowing ratio variations are assumed to have a truncated Gaussian distribution with mean of 0.3 and the standard variation of approximat...
IDDQ test is a valuable test method for semiconductor manufacturers. However, its effectiveness is reduced for deep sub-micron technology chips due to rising background leakage. Current two test methods that promise to extend the life of IDDQ test are Current Ratio and Delta-IDDQ. Although several studies have been reported on these methods, their effectiveness in detecting defects has not been...
