J. Cent. South Univ. (2019) 26: 3034-3044 DOI: https://doi.org/10.1007/s11771-019-4234-0 Energy efficient resource allocation for D2D multicast communications ZUO Jia-kuo(左加阔)1, YANG Long-xiang(杨龙祥...) multicast communications is investigated. To achieve fair energy efficiency (EE) among different multicast groups, the max-min fairness criterion is used as the optimization criterion and the EE......
β-SrRh2O4 and spinel ZnRh2O4[J]. Physical Review B, 2007, 75: 035121. [9] BANERJEE A, SINGH Z. System Zn-Rh-O: heat capacity and Gibbs free energy of formation using differential scanning calorimeter... the energy is 0-8.44 eV, the reflection index increases with increasing energy, and decreases to the minimum till 11.98 eV, and then increases with the increase of the energy again till 13.762 eV......
at temperatures of 1973, 2073, 2173, and 2273 K. The standard molar Gibbs free energy change of dissolving pure liquid element i(l) for forming 1% (mass fraction) element i in Ti-Al binary melts further was deduced. With the aid of this model, meanwhile, the determined excess thermodynamic properties, such as the excess molar mixing Gibbs free energy/entropy/enthalpy were also calculated. Key words......
proved that the required energy for crystallization of glass in the lower temperature range includes the interfacial energy between glass and crystalline phase and the free energy difference of atoms... ℃). The activation energy of LAS glass is different in different temperature ranges, which indicates different crystalliza- tion mechanisms. Fig.5 Plot of ln(-ln(1-X)) vs 1/T According to McMILAN[17], the free......
Investigation on the Free and Restrained Shrinkage of Self-compacting Concrete胡曙光摘 要:<正>A novel ellipsis-ring cracking apparatus with an automatic monitoring system was used to measure the restrained shrinkage and initial cracking time of self-compacting concrete (SCC). The free shrinkage, restrained shrinkage and strength were integrated......
range of 20-80 nm, which is confirmed by transmission electron microscopy (TEM) and X-ray diffraction (XRD). Therefore, the volume fraction of the dispersoid free zones is greatly reduced and the motion... temperature and 300 °C were increased by 20% and 13% respectively, while the minimum creep rate at 300 °C was reduced to only 1/5 of the base alloy free of TiB2, exhibiting a considerable improvement......
