The political upheavals that erupted in Kenya after the release of the 2007–8 election results resulted in the death of approximately 1 200 people, as well as the loss of livestock and other valuable property. While the Kenyan government tried to seek solutions to the crisis, the International Criminal Court (ICC) issued warrants for the arrest of top government officials. For its part, the African Union (AU) accused the ICC of racism by targeting only African leaders, and maintained that such practices undermine the rule of equality before the law set forth in Article 27 of the Rome Statute. The AU is therefore advising African countries, including Kenya, to consider withdrawing from the ICC. Will the ICC's intervention into the situation in Kenya bring justice and peace to the country, or will it add to the existing injuries affecting not just the country but the region as well? Through a critical analysis of contemporary scholarly discourse, this article unravels the dilemma of the ICC's intervention and the likely consequences of this action for the people of Kenya and Africa. 相似文献

基于双经纬仪的火炮瞄准校验系统需要给出其校验精度,但传统的测量不确定度传递公式需要大量微分运算,校验精度计算很复杂,为此,提出了基于Monte-Carlo方法的火炮瞄准校验系统测量不确定度的评定。以调炮精度校验为例分析了校验系统的原理,结合调炮精度校验过程设计了基于Monte-Carlo方法的测量不确定度评定过程,分析比较了计算量的大小,并将评定结果与传统评定方法的结果进行比较。结果表明:二者一致性良好,Monte-Carlo方法能够完成对瞄准校验系统各校验项目的校验精度评定,并且简化了计算,节省了时间。 相似文献

ABSTRACTRecent efforts aimed at understanding women’s contributions to nonstate armed groups have produced large-scale data sets on female combatants (Wood and Thomas 2017) and more limited data on women’s roles as supporters and leaders in armed groups (Henshaw 2016; 2017, Loken 2018). The present study aims to build on this literature by providing new data on the scope of women’s leadership in insurgent groups. While existing quantitative literature has focused mostly on the experience of female combatants, we argue that the presence of women in leadership roles is crucial to understanding how gender might influence the outcomes of insurgency. We introduce new data on over 200 insurgent groups active since World War II. While our analysis confirms earlier small-sample work demonstrating women’s presence in leadership roles, a qualitative analysis reveals that leadership is often gendered–revealing patterns of tokenization and tracking women to low-prestige leadership roles. At the same time, our findings challenge past research on jihadist organizations, showing limited expansion in the authority of women. 相似文献

Infrared target intrusion detection has significant applications in the fields of military defence and intelligent warning. In view of the characteristics of intrusion targets as well as inspection difficulties, an infrared target intrusion detection algorithm based on feature fusion and enhancement was proposed. This algorithm combines static target mode analysis and dynamic multi-frame correlation detection to extract infrared target features at different levels. Among them, LBP texture analysis can be used to effectively identify the posterior feature patterns which have been contained in the target library, while motion frame difference method can detect the moving regions of the image, improve the integrity of target regions such as camouflage, sheltering and deformation. In order to integrate the advantages of the two methods, the enhanced convolutional neural network was designed and the feature images obtained by the two methods were fused and enhanced. The enhancement module of the network strengthened and screened the targets, and realized the background suppression of infrared images. Based on the experiments, the effect of the proposed method and the comparison method on the background suppression and detection performance was evaluated, and the results showed that the SCRG and BSF values of the method in this paper had a better performance in multiple data sets, and it’s detection performance was far better than the comparison algorithm. The experiment results indicated that, compared with traditional infrared target detection methods, the proposed method could detect the infrared invasion target more accurately, and suppress the background noise more effectively. 相似文献

轨道机动会引起在轨卫星的轨道异常,是空间态势感知的重点关注对象之一。为此,提出一种从卫星的两行轨道要素编目数据中检测历史机动的方法。通过分析预报误差检测轨道参数的异常编目值,进而获得相应的历史机动信息。对卫星的两行轨道要素编目数据两两预报求差得到预报误差的样本数据后,利用期望最大化算法可以拟合得到以高斯混合模型表达的预报误差的概率分布模型;以此为基础,可以确定利用预报误差检测轨道参数异常编目值的门限;利用轨道机动与异常编目值之间的对应关系,最终实现机动检测。对典型活动卫星的机动检测结果表明,所提方法能够在准确检出历史机动事件的同时保持较低的误检率。 相似文献
