Lingyang Song,Zhu Han,Chen Xuy. Landsat MSS and ETM+ data are used to map change in urban patterns, while an unsupervised classification produces a land use map for the city and its environs. SRTM data are used to build an elevation model which is analyzed in conjunction with the land use map. Zones of vulnerability to floods a发誓放弃 发表于 2025-3-23 21:25:43

Cross-Layer Optimization,cause interference to cellular UEs, the scheduling and allocation of channel resources and power to D2D communication need elaborate coordination. Thus, cross-layer optimization is considered in this chapter. In Section 4.1, both system throughput and fairness are taken into account. A joint time-doALB 发表于 2025-3-24 22:32:20
