中国学生论文研究如何瘫痪美国电网 引发美方警觉

塔利班应该立马高薪聘他做高级顾问。:D

的确是个人才啊

理论和实践还是有距离的，当让理论的作用也是巨大的

据说所谓“地球一小时”的关灯动作也是有风险，如果用电量向下波动太大也会引起电网故障

    用实践来检验理论,同时用实践促成理论的发展....塔利班快行动吧...

Abstract

The vulnerability of real-life networks subject to intentional attacks has been one of the outstanding challenges in the study of the network safety. Applying the real data of the US power grid, we compare the effects of two different attacks for the network robustness against cascading failures, i.e., removal by either the descending or ascending orders of the loads. Adopting the initial load of a node j to be Lj=[kj(Σmset membership, variantΓjkm)]α with kj and Γj being the degree of the node j and the set of its neighboring nodes, respectively, where α is a tunable parameter and governs the strength of the initial load of a node, we investigate the response of the US power grid under two attacks during the cascading propagation. In the case of α<0.7, our investigation by the numerical simulations leads to a counterintuitive finding on the US power grid that the attack on the nodes with the lowest loads is more harmful than the attack on the ones with the highest loads. In addition, the almost same effect of two attacks in the case of α=0.7 may be useful in furthering studies on the control and defense of cascading failures in the US power grid.

Keywords: Cascading failure; Attack; US power grid; Critical threshold; Tunable parameter

这种攻击对于中国和美国这种大国只能起到短期效果。塔利班用比较合适，TG是绝对不会这样对付美国的。

谁让米帝的电网太过老旧脆弱，一写论文自然而然就...这也是没办法的事

确定是大连理工而非蓝翔技校吗？

kengqiangmeigui 发表于 2010-3-24 20:17

蓝翔技校的人正在研究怎么整火星人，地球上的人家没有兴趣。

人家帮你指出电网不足，你应该感谢人家

实际上美国电网的老旧和脆弱是人所共知的，特别是美国人自己。。。。。。。。

    实际上美报曲解了那篇论文，而且貌似论文名也不是那个，只不过是美标题党而已

偶们也一样，08年南方冻雨就说明一切了{:wugu:}
