reliable Cluster Head(CH) selectionbased routing protocols are necessary for in.r..sing the packet transmission efficiency with optimal path discovery that never in.r..uces degradation over the transmission.r..iability. In this paper, Hybrid Golden Jackal, and Improved Whale Optimization Algorithm(HGJIWOA) is proposed as an effective and optimal routing protocol that guarantees efficient routing of data packets in the established between the CHs and the movable sink. This HGJIWOA included the phases of Dynamic Lens-Imaging Learning Strategy and novel Update rules for determining the reliable route essential for data packets broadcasting attained through fitness measure estimation-based CH selection. The process of CH selection achieved using Golden Jackal Optimization Algorithm(GJOA) completely depends on the factors of maintainability, consistency, trust, delay, and en.r... The adopted GJOA algorithm play a dominant role in determining the optimal path of routing depending on the parameter of reduced delay and minimal distance. It further utilized Improved Whale Optimisation Algorithm(IWOA) for forwarding the data from chosen CHs to the BS via optimized route depending on the parameters of en.r.. and distance. It also included a reliable route maintenance process that aids in deciding the selected route through which data need to be transmitted or re-routed. The simulation outcomes of the proposed HGJIWOA mechanism with different sensor nodes confirmed an improved mean throughput of 18.21%,sustained residual en.r.. of 19.64% with minimized end-to-end delay of 21.82%, better than the competitive CH selection approaches.

当外界扰动频率接近块系岩体的固有频率时,会出现准共振现象。这一现象导致岩块间的弱夹层应变急剧变化,从而加快弱夹层的动态损伤断裂。为了研究块系岩体准共振导致岩块间弱夹层的动态拉压损伤断裂规律,基于块系岩体模型,分析准共振状态下弱夹层的变形特征。结合岩石动态损伤断裂准则,对准共振状态下弱夹层的动态损伤断裂进行理论计算分析,进而研究动态破坏规律。通过数值模拟揭示了准共振状态下块系岩体中弱夹层的损伤演化特征。结果表明:当块系岩体发生准共振现象时,岩块间的相对位移急剧增加,使得弱夹层的应变和损伤程度明显增大;弱夹层的损伤程度在准共振频率下最高,同时受外部扰动力和弱夹层的刚度、黏性、厚度及岩块质量等系统参数的影响;块系岩体发生准共振时断裂应力增大,但从断裂到完全破坏的时间明显缩短,即残余承载能力大幅下降。该研究对认识块系岩体的动态断裂具有一定的参考价值。
