The cycle frosting and defrosting performance of two types of microchannel heat exchangers were investigated. All the processes were observed using a CCD camera to better understand the cycle frost mechanism. Ice blockage formed in the fin root gaps of the horizontal-tube sample because of water...

Given sequences of finite-state trials, an almost perfect match means that there exists at least k-1 matches between any subsequences of size k in each sequence. Let X1,X2,... be a sequence of {0,1}-valued Markov dependent random variables each resulting in either a match (Xi=1) or mismatch...

In this study, we constitute an adaptive hedging method based on empirical mode decomposition (EMD) method to extract the adaptive hedging horizon and build a time series cross-validation method for robust hedging performance estimation. Basing on the variance reduction criterion and the...
