Researches of the decoupled method for reliability-based optimization [PDF]
, 2016 可靠性优化设计方法是工程结构设计中的一种非常具有优势的设计方法，其中，该方法的求解效率和求解精度是研究的重点。解耦策略是解决结构可靠性优化设计中包含复杂或隐式极限状态、多设计变量、小失效概率问题的一种高效可行的办法，它的关键在于建立失效概率的近似表达式，也就是求解失效概率函数。因此，研究高效求解失效概率函数近似的方法，以及提高优化效率和精度的解耦优化策略对于解决工程结构中的可靠性优化设计问题具有重要的作用。本文围绕上述问题展开研究工作，主要内容包括如下几个部分。 1.基于失效概率函数的概念 ...

Real-time System Fault Tree Minimal Cut Sets Solving [PDF]
, 2014 对于传统系统，实时系统的安全性和可靠性的分析缺乏类似的定量评价方法。故障树分析是已被广泛应用于许多行业的系统可靠性分析方法，然而，由于它的语义表达能力有限，因此不能够在实时系统中进行与复杂顺序依赖和时间约束有关的可靠性分析。文章将故障树的语义进行延伸，使复杂顺序依赖和时间约束可以够被故障树所表示，并使故障树分析方法应用到实时系统中。 但是，故障树的最小割集的不能由传统方法求解在延伸语义之后。针对此问题，文章采用时间自动机对实时系统的故障树进行建模，并在其基础上使用模型检验的方法求解最小割集。验证表明 ...

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.ABSTRACT Bangladesh's goal of achieving high‐income status by 2041 requires dependable, low‐emission, and affordable energy. With near‐universal grid coverage and increasing demand, nuclear energy is a strategic asset for long‐term baseload supply. However, the existing financing model, typified by the country's most expensive $12.65 billion Rooppur ...

Design and Realization of Talent Resources Statistical System in Guizhou Province [PDF]
, 2015 为了摸清贵州省人才资源家底，全面动态掌握贵州省人才资源发展、分布等情况，贵州省人才工作领导小组决定在全省范围内开展全口径人才资源统计。全口径人才资源统计涉及面广，包括全省党政机关、事业单位、公有制经济领域企业、非公有制经济领域企业和农村实用人才等人才队伍，覆盖贵州省9个市州和88个县区，统计工作量大，如采用纸质或Excel表格上报不现实，数据汇总分析难度较大，且误差也较大。因此，研究设计贵州省人才资源统计网络直报系统是完成全省人才资源统计的最好途径。 本论文主要研究贵州省人才资源统计网络直报系统需求分析、
