基于有向加权网络的高处坠落事故致因分析

为了了解高处坠落事故致因的复杂性,减少类似事故的发生,收集210个高处坠落事故案例,通过事故链分析技术获取致因关系,整合构成有向加权网络;运用复杂网络理论对致因网络特征进行分析,得出高处坠落事故致因的演化关系,提取了现场安全监管不足和安全意识淡薄两个关键节点,并根据致因联系强度对重要节点的控制提出建议.本研究有助于揭示高坠事故致因内在联系和演化特征,控制关键致因提升管理效率.

Statistical Separability of the World and Consistency Between Quantum Theory, Relativity, and Causality

We show that the quantum world with non-local states and original statistics is statistically separable. According to relativistic dynamics, the super-luminal signal transmission is impossible. The present quantum theory is therefore consistent with the relativity and the causality.
