光纤光栅技术与应用专题讲座(三) 第6讲 光纤光栅传感技术在土木工程中的应用

针对利用光纤光栅进行应变、温度等测量已经在土木工程中较为普遍这一现状,首先对光纤光栅传感技术进行应变、温度等测量的基本原理进行了描述,重点讨论了为满足耐久性、安装方便与温度自动补偿等需求光纤光栅传感器的封装技术,最后介绍了光纤光栅传感器在土木工程中实际应用的现状。     

Honour,Comradeship and Betrayal: Lord Capel’s Sword

The sword which is the subject of this article and which will be referred to as the Capel sword, is a fine example of what has become known as an Irish basket-hilt. Whilst there are other examples in existence, what makes this sword unique and particularly important is the fact that it is known to have been owned by two important Royalist military leaders, Lord Arthur Capel and Sir John Owen. These two extraordinary men came from different backgrounds but their fate was linked through circumstances beyond their control. The story this sword tells is one of comradeship, loyalty, total belief in a cause, betrayal and ultimate sacrifice.     

一般民用建筑火灾特点与起火部位认定

从建筑火灾特点出发,阐述了建筑火灾发展阶段的蔓延特点、烟气流动特性与起火部位的内在联系,说明这些建筑火灾特点对起火部位的认定作用。     

高层民用建筑消防安全隐患及对策

随着高层民用建筑的不断增多,其消防安全问题受到社会各界广泛关注。从消防安全隐患的产生、消防管理、建筑地下部分的火灾危害、消防部队装备几个方面分析了高层民用建筑的消防安全隐患。从把好建筑设计、审核、验收关,强化消防安全管理,强化消防宣传教育,加强消防产品与消防工程施工的监管,完善灭火救援体系等方面提出了提高高层民用建筑消防安全的对策。     

Subcontracting State-Building

Abstract

Contemporary development assistance often takes the form of subcontracted state-building. Foreign donors hire for-profit firms to provide services and to improve or create institutions in developing countries, particularly those experiencing internal conflict. This arrangement creates two counterproductive dynamics: first, it introduces agency problems between donors, recipient states, subcontractors, and citizens; and second, it undermines the long-run development of domestic bureaucratic capacity by creating disincentives for the host government to invest. These dynamics hinder, rather than foster, the legitimacy of state institutions. This paper summarizes trends in external support to state-building since the 1970s and illustrates subcontracted state-building with examples from Colombia.     

基于族群机制的花朵授粉算法

针对花朵授粉算法易陷入局部极值、收敛速度慢等不足,提出一种具有族群机制的花朵授粉算法。该算法把种群分成多个族群,各族群的最优个体再组成新的种群,进而促进种群间的信息交流,有效地协调种群进化过程中的全局搜索和局部搜索能力,避免个体的早熟收敛,提高算法的全局寻优能力及收敛速度。通过8个CEC2005benchmark测试函数进行测试比较,仿真结果表明,改进算法的寻优性能明显优于基本的花朵授粉算法、粒子群算法和蝙蝠算法,其收敛精度、收敛速度、鲁棒性均较对比算法有较大提高。     

Resource rents,institutions, and violent civil conflicts

Natural resources have been blamed for inducing slow growth and sparking civil conflicts and violence. This paper first develops a model to account for the hazard of armed civil conflicts as a manifestation of the natural resource curse, which is mediated by the quality of both economic and political institutions. We then use recently published data on institutional quality and natural resource rents to measure the potential impact of the resource curse on violent civil conflicts using a panel of data for over 100 countries in the period 1970–2010. Our model explicitly accounts for the role of good economic and political institutions in deterring the recourse to violence as well as the extent to which they might weaken the resource rents effect.     

民俗习惯在民事审判中司法适用的实证分析

当今的司法审判始终显现着一种特殊现象,即无论成文法如何完备,民俗习惯总会渗透到民事活动中施加规范性影响,这一态势在基层社会生活中尤其明显。而在司法代表国家意志对这些民事活动进行评价时,审判者也无时无刻不感受着民俗习惯的那份坚守。关注民俗习惯在基层法治生态中的价值,通过实证研究的方式解构民俗习惯在司法实践过程中的应用,来展示可使审判者把握此种影响的客观规律,分析在法制体系下如何合理、准确、高效地适用民俗习惯。     

浅析武警部队“能打胜仗”核心军事能力建设

习主席关于“能打仗、打胜仗”是强军之要的重要思想,是对党的建军治军思想的继承和发展,有着很强的指向性,为在新的历史起点上加快推进国防和军队现代化建设指明了方向。贯彻落实好“能打仗、打胜仗”重要思想,必须按照打仗的标准搞建设抓准备,确保武警部队始终能够召之即来、来之能战、战之必胜。     

维吾尔族数学文化调查分析

维吾尔族传统文化中包含着丰富的数学元素。充分挖掘和展示维吾尔族文化中的数学知识,重视课程资源开发,提倡数学学习方式的多样化,深化多元文化视野下的数学教育对于推进少数民族地区数学课程改革具有积极的现实意义。此外,有关民族数学教育学的理论体系的建立及实践探索也是必须涉及的一个重要方面。
