The shapes of metallogenic basins are composed of tilting ramp, fault-tip ramp and relay ramp, which dominate migration of gravity current of ore-hosted fluid and shape of orebody sedimentary fan in the ramp. By measuring and comparing the difference of length-to-thickness ratios of orebody sedimentary fan, the result shows that the occurrence of the ramp has a remarkable impact on the shape of orebody.展开更多

In this article, a systematic GMPLS-based recovery mechanism is proposed using enhanced link management protocol （LMP）, which can support bidirectional fault notification relay more effectively. The major contributions and propositions in this article involve： 1） Soft-protection configuration for higher resource utilization with optimized routing; 2） Intelligent Shift from protection manner to restoration manner for the reduction of recovery latency; and 3） Toggleable revertive mode to increase restoration flexibility and to reduce loss of stability. Additionally, by leveraging valuable legacy including shared risk link group （SRLG） processing and fast reroute technique, the proposed recovery mechanism achieves higher resource utilization, fast and robust operation, satisfactory stability and flexibility, and is convenient in the apphcation over heterogeneous transport networks.展开更多
