基于目标识别的飞机偏离跑道测量技术

为了有效地避免飞机偏离跑道造成的事故,运用目标识别技术,对机场跑道的标线中心线和表示飞机滑跑方向的轮廓线进行了提取,并且进一步测量出标线的方向和飞机滑跑的方向,计算出两者之间的夹角.从而对飞机偏离跑道进行了定量的测量.实验表明,该技术测量的速度快,耗时少,且测量结果准确,能够有效地对飞机在跑道的滑跑情况进行监控,是一种有用的技术.     

农村小企业消防安全现状及对策研究

20世纪80年代兴起的农村工业小企业，为改革开放初期的经济发展发挥了显著作用，但由于在经济建设及发展过程中缺乏科学有效规划和消防安全管理，遗留了诸多火灾隐患。以福州市仓山区为例，深入分析了农村工业小企业存在的火灾隐患问题，并从火灾隐患的消防技术整改和强化消防管理两个方面提出具体对策。     

基于偏差熵的专家聚类赋权方法

在群决策专家聚类赋权过程中,可能出现专家给出的判断矩阵一致性比率与排序向量信息熵都相等但专家意见不同,却被赋予了相同权重的情况。针对上述问题,提出一种基于偏差熵的专家聚类赋权方法。该方法采用聚类分析的思想,基于比例构建相似系数,实现对专家群的分类;引入专家判断矩阵的一致性权重,并综合类容量构建权重指标来反映类别间的差异,确定专家类间权重;最后,在各专家类中建立偏差熵模型,依据类中专家达成一致性意见的贡献程度确定专家的类内权重,并得到专家的总体权重。具体算例表明,该方法可行有效。

The structural origins of social cohesion: the dynamics of micro-solidarity in 1991–1995 Wars of Yugoslav Succession

This article explores the dynamics of social cohesion on the frontline. It attempts to show how micro-level solidarities largely depend on macro level organisational processes. I argue that frontline social cohesion is often the product of social development linked with the organisational structure. This general argument is applied to the case studies of two armed forces involved in the 1991–1995 Wars of Yugoslav Succession – the Croatian Army (HV) and the Bosnian Serb Army (VRS). Drawing on in-depth interviews with the former combatants I show how HV social cohesion played an important role in winning the war and how these networks of micro-level solidarity were shaped by long term organisational development.     

The strategic purpose of individual augmentee officers for junior partners in multinational military operations

ABSTRACT

This article examines the strategic purpose of Individual Augmentee Officers (IAOs) for junior partners in multinational military operations through an exploratory case study of Danish IAOs in Iraq and South Sudan between 2014 and 2017. IAOs are individual officers who are moved from their normal functions to be seconded to other units of the armed forces of their own or another country or an international institution. The study concludes that IAOs function as strategically important, yet not necessarily indispensable, supplements to military contingents in several ways: making tangible contributions to the overall mission (contributing), gaining access to information, knowledge, and experience (learning), and lobbying decision-making processes within mission headquarters (lobbying). The usefulness of IAOs depends on whether the junior partner has specific interests and a significant presence in the theatre and whether the mission is conducted as a UN mission, a NATO mission, or an ad hoc coalition.     

The ‘first’ surge: the repulse of the Easter Invasion in South Vietnam, 1972 – implications for Iraq and Afghanistan

In a military intervention, do surges work? I compare the failed ‘surge’ in Vietnam, the repulse of the Easter Invasion in 1972, as a means of assessing the more ambiguous surges in Iraq and Afghanistan. I identify four features of a surge for this analysis: the military dimensions and strategy of the surging forces, the military capabilities of the host forces, the political vitality and will of the host country, and the political commitment in the domestic politics of the intervener. I find that the last feature is the most critical; and, in all three surges, the American political commitment was lacking.     

基于离差最大化的对地攻击型无人机作战效能评估

针对传统作战效能评估方法在确定权重系数时的主观随意性较大等问题,提出采用离差最大化方法来评估无人机作战效能。首先建立了攻击型无人机空地作战效能指标的层次结构,然后建立了基于离差最大化的攻击型无人机空地作战效能评估的数学模型,并给出了各分项能力的计算模型,最后以6种无人机空地作战效能评估为例,计算并验证了模型的有效性和合理性。     

小散远部队单位疫情防控工作思考【专题】

重大疫情具有突发性强、危害性大等特点，一旦发生，极易在防疫准备不充足的小散远部队单位造成爆发。加强基层疫情防控基础建设贵在平时，势在必行。本文首先对重大疫情的特点和小散远部队单位防疫工作面临的现实困难进行了分析，并对开展新时代基层单位疫情防控工作进行了思考，最后提出了应在思想政治教育、军地联动、心理辅导和防疫效果评估等方面予以加强的小散远部队单位疫情防控工作系统框架，以期为提高部队基层防疫效率提供参考。     

小子样多失效模式系统可靠性竞争模型

为解决小子样多失效模式系统可靠性模型参数的估计问题,首先应用支持向量积建立小子样条件下各故障模式的规律模型,其次利用模型将各故障模式的故障数据由小子样扩充成大样本,再次采用常规的参数估算方法估算各故障模式的分布参数,最后建立多失效模式系统的可靠性竞争模型。利用所提方法,建立了小子样条件下具有两种失效模式的柴油机汽缸套可靠性竞争模型,计算结果与大样本条件下的故障预测数据吻合度较高,说明了方法的有效性。
