基于修正G1和Vague集的川藏铁路重大桥梁桥位评价研究

为指导复杂地形地质条件下艰险山区铁路--川藏铁路的重大桥梁工程桥位选择,针对川藏铁路沿线特征,以减灾为核心,以工程技术、工程经济、施工条件、地形地质、水文气候、生态影响6个方面17个指标建立指标体系,基于CRITIC(Criteria Importance Though Intercrieria Correlation, CRITIC)-G1(Order Relation Analysis Method, G1)法组合赋权和Vague集-TOPSIS法(Technique for Order Preference by Similarity to an Ideal Solution, TOPSIS)多属性模糊决策建立川藏铁路重大桥梁桥位评价模型。应用模型对川藏铁路怒江大桥桥位进行评价,得到丢攻高桥方案为最优桥位方案。结果表明:指标体系对川藏铁路桥位方案评价具全面性和针对性;CRITIC修正G1法组合赋权能提高指标赋权合理性;Vague集-TOPSIS法模糊决策能提高川藏铁路重大桥梁桥位模糊评价的准确性,模型评价结果合理可靠,可为铁路重大桥梁桥位选择提供合理可行的决策方法。

Making public policy through citizen committees: Case histories from the Islands

Abstract

Citizen committees properly designed can strongly influence public policy. Examples are taken from the results of reports on marine affairs that citizen committees wrote in Hawaii, the U.S. Virgin Islands and Puerto Rico. Community acceptance and use of each report came about because (1) many members of the committees were in positions to act on the recommendations, (2) the recommendations were specific and called for actions other than studies, and (3) the governor of each area had asked that a report be drawn. To ensure attention to the reports, each governor had agreed that they would be uncensored, widely publicized, and released concurrently to the public and the government.     

Stakeholder Collaboration and Organizational Innovation in the Planning of the Deschutes Estuary Feasibility Study

Coastal managers have sought to enhance the collaborative inputs of stakeholder groups into management activities. Nonetheless, established organizational approaches have led to primarily consultative forms of engagement and constrained citizen involvement in formative activities. In Olympia, Washington, managers overseeing the Deschutes Estuary Feasibility Study (DEFS) implemented an innovative cooperative research planning initiative that diverged from conventional consultative processes. Stakeholders, rather than government officials, identified the research priorities for the socioeconomic component of this restoration feasibility study. This design method altered the traditional roles and responsibilities of different organizational actors, and the involvement of citizen groups in these formative activities changed the relationship between governmental and nongovernmental actors. Using conceptual frameworks from organizational sociology, this study develops insights into the behavior of the organizations involved with the DEFS cooperative planning effort, demonstrating how engaging stakeholders in formative research planning activities may foster new types of collaboration among coastal management organizations.     

智能网联先导区道路交叉口车路协同系统设计

近年来,车路协同是汽车与交通行业发展的重要方向之一,而车路协同环境建设和推广也成为先导区建设的重中之重。车路协同系统利用无线通信、传感器检测、高精度地图定位、人工智能、计算机等众多技术来获取车辆和道路信息,在实现人、车、路充分协同的同时,从而达到主动提高道路交通安全、最优化利用系统资源、缓解交通拥挤的目标,形成安全、效率、环保的道路交通系统。先导区一般选址在车流量大、道路环境复杂、附近居住人口密集的区域。先导区内汽车智能与网联化测试、V2X场景实现均需要借助于车路协同系统环境。本文介绍了先导区道路交叉口车路协同系统涵盖的技术,以及实现的功能和信息服务场景,并从车端、路端给出了相应场景的解决方案。     

基于VW-PCA的盾构刀盘驱动液压系统故障诊断

为提高盾构刀盘液压系统故障诊断的快速性和准确性,引入权值向量来改进传统主元分析法（PCA）,并推导变量加权主元分析法（VW-PCA）公式。通过AMESim仿真软件建立6 450 mm土压平衡盾构刀盘驱动液压系统模型,选取12个测试变量,模拟仿真6种故障状态; 运用仿真故障数据得到每一类故障的加权向量,建立变量加权主元分析模型（VW-PCA）,并使用该模型对测试故障样本进行研究。结果表明： 变量加权(VW) 能够增强各系统变量对不同故障类型的贡献程度,变量加权主元模型（VW-PCA）能够显著提高系统诊断的正确率,最大可提高50%以上。
