A Probabilistic Model for the Failure Frequency of Underground Gas Pipelines

A model is constructed for the failure frequency of underground pipelines per kilometer year, as a function of pipe and environmental characteristics. The parameters in the model were quantified, with uncertainty, using historical data and structured expert judgment. Fifteen experts from institutes in The Netherlands, the United Kingdom, Italy, France, Germany, Belgium, Denmark, and Canada participated in the study.     

新产品开发决策信息的筛选

新产品的开发其实是企业对消费者发送的需求信息的反馈过程,其成功与否取决于二者间信息传递的速度和准确性.因此,新产品开发部门要做的重要工作之一就是过滤这些大量的复杂而模糊的信息.实际操作中,新产品开发部门应建立科学的决策信息收集模式,并建立有利于信息交流的工作方式.     

基于政府干预的民族地区行政价值趋向分析

本文从民族地区政府"现代化"观念的特有逻辑、后发现代化的现实悖论以及民族地区后发现代化的政府与社会之间的合理关系,探讨民族地区行政"政府干预"的经验以及社会经济发展的"共时性"要求对民族地区"政府干预"的实践诉求,旨在加速民族地区的现代转型。     

当代分裂主义与外部环境

对分裂主义的历史经验考察证明，分裂主义受事发国政府态度、自身内部因素、国际环境等多种因素的制约，而外部的介入常常成为决定分裂成败的关键。外部势力对分裂主义问题的干涉，包括给予分裂主义势力物质支持、政治外交支持，甚至是进行武装干涉。外部势力对分裂主义问题的干涉，将导致国际分裂主义危机的爆发。     

Dimensions of work-home culture and their relations with the use of work-home arrangements and work-home interaction

This study examined the associations of work-home culture with (a) demographic and organizational characteristics, (b) the use of work-home arrangements, and (c) negative and positive work-home interaction, among 1,179 employees from one public and two private organizations. Substantial support was found for a 2-factor structure of a work-home culture measure differentiating between “support” (employees' perceptions of organization's, supervisors', and colleagues' responsiveness to work-family issues and to the use of work-home arrangements) and “hindrance” (employees' perceptions of career consequences and time demands that may prevent them from using work-home arrangements). This 2-factor structure appeared to be invariant across organizations, gender, and parental status. Significant relationships with organizational characteristics, the use of work-home arrangements, and work-home interaction supported the validity of these two cultural dimensions. It is concluded that if employers want to minimize work-home interference, to optimize positive work-home interaction, and to boost the use of work-home arrangements, they should create a work-home culture that is characterized by high support and low hindrance.     

油藏Voronoi网格化的研究

Voronoi网格具有很强的灵活性和局部正交等特点,可以把局部细分网格与基本粗化网格有效地结合在一起,满足了油藏数值模拟技术对于大范围粗格化模拟、局部精细化描述的需要。对Voronoi网格的生成技术进行了分析和研究,提出了一种新的生成方法：把油藏区域按断层、井层、基层分层,针对不同层,采用不同的几何模型布点,最后采用间接法构造Voronoi网格。从计算几何的角度把层干扰归纳为点与点、点与线和线与线3类,并给出了相关的解决措施,重点对断层与垂直井、水平井的干扰进行处理。通过Voronoi网格化模型,验证了该算法的正确性和有效性。

SOJ干扰下雷达网检测性能分析

通过建立SOJ干扰时雷达的检测概率分布模型,研究了雷达网在秩K准则和Neyman-Pearson准则时检测概率分布,仿真了不同准则时雷达网的检测概率分布图,分析比较了以上2种融合准则的融合性能.通过仿真发现,雷达网检测概率分布图克服了传统方法利用单个空间位置检测概率描述雷达网性能的局限性,并且为干扰下雷达网融合准则的选取提供了一个更全面、更直观的参考.
