实际中由于多种因素的存在使得对消性能下降,以最小均方准则下的旁瓣对消原理为基础,详细分析了实际中几种重要的因素对自适应旁瓣相消性能的影响,包括辅助天线中信号分量、主辅通道响应不一致、主辅天线间距的影响,最后通过仿真验证了旁瓣对消性能。结果表明,旁瓣对消系统可以有效地抑制有源干扰信号的影响。  相似文献

把美育纳入社会管理的过程中并确定具体的管理、田野观察点,既可以使审美育人走出学者们的课堂和书斋,解决当前我国美育建设相对势弱问题,又可以使审美育人融入社会管理和人民群众的实践中,提高实践的质量和水平。要以个案来展示影响社会管理发展的某种重要因素、这种因素的张力以及它的存在和发展逻辑,以审美育人的标准和尺度考察社会管理者的行为,群众的感受和所见所闻、所思所想,关注群众现实生活的巨变。最理想的调查方式是选择那些与研究者成长背景完全不同的观察点,会收到最佳的效果,因为这样会避免先入为主的感觉。要特别注意运用相关的理论考察社会管理创新的机理,增强整体关照能力和深刻度。要在悬置经验本位和相关理论假设的前提下得出个案研究的新结论。  相似文献

The eastern Democratic Republic of Congo (DRC) has been characterised by chaos and insecurity for a number of years, but the rise of the M23 rebellion in 2012 once again highlighted just how dire the humanitarian and security situation is. For most of 2012, the crisis was addressed through negotiations between M23 and Kinshasa, mediated by the International Conference on the Great Lakes Region (ICGLR). However, 2013 marked the signing of the Peace, Security and Cooperation Framework Agreement (PSC Framework), and the United Nations Security Council's adoption of Resolution 2098, which contains the mandate of the long-awaited Intervention Brigade (IB). The PSC Framework calls on Kinshasa to implement substantial political reforms while also urging the neighbours of the DRC to stop interfering in its internal affairs. The IB is mandated to carry out targeted operations against the so-called ‘negative forces’ that operate in the eastern DRC. For now, hope of resolving this ongoing crisis hinges on the continuing ICGLR negotiations, the implementation of the PSC Framework and the success of the IB. However, there are critical questions about all of these processes that need to be answered and understood, as the expectations for these processes – especially in the case of the IB – are extremely high. Will the ICGLR manage to negotiate a peace agreement and will the IB succeed, or will they go down in history as yet another failure to save the eastern DRC?  相似文献

Armed conflict on the African continent has witnessed increasing recruitment of child soldiers, often at the hands of non-state armed groups. Unfortunately this practice continues unabated in the face of legal obligations prohibiting the recruitment of child soldiers under international humanitarian law, and international and regional human rights law. While international condemnation of the practice has led to attempts to increase the minimum age for recruitment to 18, a disjuncture persists between the legal obligations states sign up to, and the actual enforcement of these prohibitions at a domestic level.

International criminal law jurisprudence emanating from the Special Court for Sierra Leone and the International Criminal Court is being monitored closely, as these courts seek to enforce the prohibition in all armed conflicts, and against both state actors and non-state armed groups. International humanitarian law only protects child soldiers who have been unlawfully recruited. In this piece, the authors take a closer look at what amounts to unlawful recruitment in light of customary international humanitarian law, since this body of law also binds non-state actors, even without further criminalising legislation at a domestic level. Moreover, the article briefly explores whether a child can ever void this protected status by volunteering to participate directly in hostilities.  相似文献

In principle, national sovereignty is the right of a nation to govern its internal affairs without foreign interference. In practice, it is defined by one's interpretation of international law, which may permit legal external intervention under some circumstances, ultimately removing a nation's sovereignty. This paper will examine the current system of international law outlined by the United Nations, analyse the ambiguities contained within its Charter and elaborate on how external intervention can be justified. The case-study of recent developments related to Libya will demonstrate that the manner in which international law is interpreted is changing the notion of principles of sovereignty.  相似文献

During the Nigerian Civil War (1967–1970), France chose to support Biafra, but only on a limited scale, providing mercenaries and obsolete weaponry to Ojukwu's regime. General Charles de Gaulle's assistance to Ojukwu was conditioned by the French military drawdown after 1961, the increased power of French secret services on the continent, and the interventions in Katanga (1960–1963), Gabon (1964) and Chad (1968–1972). France supported Biafra primarily to protect its former colonies from Nigeria, stop Soviet subversion and acquire an economic foothold in the oil-rich Niger Delta. De Gaulle chose a limited strategy for two reasons. If Biafra won the war, France would be Biafra's greatest ally. If Nigeria won the war, France could extricate itself from the situation relatively easily and re-establish relations with the Nigerian government, which is what ultimately occurred.  相似文献

针对现有多拓扑路由在多故障条件下无法有效进行故障恢复的现象,根据免疫理论中抗原与抗体相匹配的原理,提出一种多拓扑路由子层选择算法.该算法以最大限度保护通信业务为目标,将多故障情形与子层相匹配的过程看作抗体与抗原相结合的过程,使子层与故障在一定范围内最大程度地相似,并利用人工免疫算法进行寻优,提高了网络抗毁性.实验结果表明,该算法可使网络在多故障条件下的恢复能力得到提高.  相似文献

Both heating and solvent-spray methods are used to consolidate the standard grains of double-base oblate sphere propellants plasticized with triethyleneglycol dinitrate (TEGDN) (TEGDN propellants) to high density propellants. The obtained consolidated propellants are deterred and coated with the slow burning multi-layer coating. The maximum compaction density of deterred and coated consolidated propellants can reach up to 1.39 g/cm3. Their mechanic, deconsolidation and combustion performances are tested by the materials test machine, interrupted burning set-up and closed vessel, respectively. The static compression strength of consolidated propellants deterred by multi-layer coating increases significantly to 18 MPa, indicating that they can be applied in most circumstances of charge service. And the samples are easy to deconsolidate in the interrupted burning test. Furthermore, the closed bomb burning curves of the samples indicate a two-stage combustion phenomenon under the condition of certain thickness of coated multi-layers. After the outer deterred multi-layer coating of consolidated samples is finished burning, the inner consolidated propellants continue to burn and breakup into aggregates and grains. The high burning progressivity can be carefully obtained by the smart control of deconsolidation process and duration of consolidated propellants. The preliminary results of consolidated propellants show that a rapid deconsolidation process at higher deconsolidation pressure is presented in the dynamic vivacity curves of closed bomb test. Higher density and higher macro progressivity of consolidated propellants can be obtained by the techniques in this paper.  相似文献
