J. Cent. South Univ. (2017) 24: 2314-2321 DOI: https://doi.org/10.1007/s11771-017-3643-1 Phase type delay distribution with PU return and sensing error in CR networks Mohammad Reza Amini, Hemati... in the literature. There is also some missed idle times during the waiting phase when secondary user finds the channel busy. Therefore, the longer the transmission time is, the higher the successfully delivered......
using scanning electron microscopy(SEM) back-scatter electron(BSE) imaging and energy dispersive spectrometry(EDS). Phase compositions were measured by electron probe micro-analysis(EPMA), which... display four phases: (Mo) was the white phase, T2 was light gray phase, T1 was the dark gray phase, and D88 was the dark phase. The crystal structure of each phase was confirmed by EBSD analysis......
