考虑地磁场空间梯度的飞行器磁干扰建模与求解方法

首先,在研究飞行器背景磁干扰模型与小信号模型的基础上,分析了地磁梯度沿纬度与高度的变化规律,分析可知由于飞行器的机动,地磁梯度会对测量结果造成影响;然后,考虑地磁梯度因素,对原有小信号模型求解方法进行了改进：飞行器在四个航向上做小角度的机动飞行,将地磁场沿纬度与高度的梯度作为未知量,与飞行器磁干扰模型中的剩磁参数、感磁参数和涡磁参数一起求解;最后,利用实测试验数据进行了验证,结果表明：考虑地磁梯度的影响与不考虑地磁梯度的影响相比,求解的模型参数可以在细节上进一步提高飞行器背景磁干扰的补偿效果。     

The essence of war: French armies and small war in the Low Countries (1672–1697)

In the late seventeenth century during the Dutch War (1672–1678) and the Nine Years War (1688–1697), French armies relied on small war for the accomplishment of essential tasks and as part of an overall strategy of exhausting their opponents in the Low Countries. The purposes of small war included the imposition of contributions on enemy populations, the destruction of the enemy base of operations, blockades of fortresses, and the general support of campaign armies. The expression ‘small war’ in the French language appeared with growing frequency in the 1690s. Small war can be viewed as both a cause and consequence of the characteristics of these wars. The limited policy goals of Louis XIV the king of France required a strategy that minimised risk and accomplished the goal of reducing if not eliminating the Spanish presence in the Low Countries that bordered the north of France. As French armies increased in size during this period, the demand for specialists at small increased in order to provide security and ensure supply. Small war in the late seventeenth century was thus not ideologically motivated insurgency, but in the minds of French commanders an essential component of strategy and the nature of war.

Does Intent equal Capability? Al-Qaeda and Weapons of Mass Destruction

The prospect of terrorists deploying weapons of mass destruction (WMD) is often referred to as the foremost danger to American national security. This danger has become more realistic because of al-Qaeda's expanding global network and the expressed willingness to kill thousands of civilians. In the past four years, numerous media reports have documented the group's ongoing quest for WMD capabilities; many reports have detailed al-Qaeda members’ attempts to manufacture or obtain certain chemical, biological, radiological, and nuclear (CBRN) agents to use in WMD against targets in the West and the Middle East. Yet the question remains: Does al-Qaeda's current WMD capability match its actual intent? While most studies of the group have focused on its explicit desire for WMD, allegations of CBRN acquisition, and the killing potential of specific CBRN agents, few open-source studies have closely examined the evolution of al-Qaeda's consideration of WMD and, most notably, the merit of actual CBRN production instructions as depicted and disseminated in the group's own literature and manuals. The following report will examine the history of al-Qaeda's interest in CBRN agents, the evolution of the network's attitude toward these weapons, and the internal debate within the organization concerning acquisition and use of WMD. More so, the following research will assess the validity of actual CBRN production instructions and capabilities as displayed and disseminated in al-Qaeda's own literature and websites.     

频率搅拌混响室内小屏蔽体的场均匀性检验

为了研究频率搅拌混响室内小屏蔽体的屏蔽效能测试方法,需要检验小屏蔽体内的场均匀性．通过对混响室的场均匀性测试方法的研究,提出基于矢量网络分析仪的测试方法,通过计算工作区域任意两点的功率比检验场均匀性,并用该方法检验工作区域内小屏蔽体的场均匀性．实验结果表明：混响室采用扫频信号实现频率搅拌时,放置于工作区域的小屏蔽体内部同样有较好的场均匀性．     

具有终端约束的制导炸弹模糊变结构制导律设计

针对INS/GPS制导炸弹对地面目标的精确打击问题,提出带落角约束的模糊变结构制导律。在变结构制导律的基础上,引入终端落角约束项,应用模糊规则对所设计制导律中的变结构开关项系数增益进行在线调节。仿真结果表明,在对地面目标进行攻击时,该制导律降低变结构控制系统的抖振,同时满足制导精度和期望落角的要求,具有有效性和鲁棒性。     

Lost through non-translation: bringing Clausewitz's writings on ‘new wars’ back in

While Carl von Clausewitz has generally been respected as one of the most profound philosophers of war, his expertise has been regarded as somewhat limited if not even irrelevant to the so-called ‘new wars’ of the post-Cold War world. Many scholars in international relations have claimed that ‘new wars’ are essentially ‘post-Clausewitzian’ and ‘post-trinitarian’ in nature, meaning that they are no longer fathomable through a Clausewitzian framework. However Clausewitz's earlier writings were nearly exclusively dedicated to guerrilla warfare, or what he called ‘small wars’. These writings have been largely overlooked by many analysts of contemporary conflicts. By drawing on his rare and untranslated writings, the article uncovers a critical part of Clausewitz's expertise in asymmetric warfare and shows that, far from being irrelevant in an age where interstate warfare is increasingly being replaced by conflicts between states and semi-/non-state actors, Clausewitz's philosophical writings actually shed new light into the particular interactive dynamics generated during wars waged under conditions of asymmetry.     

FlatLFS:一种面向海量小文件处理优化的轻量级文件系统

海量小文件的高效存储和访问是当前分布式文件系统面临的主要挑战之一。以GFS和HDFS为代表的分布式文件系统大多面向海量大文件的高效存储和访问设计,缺乏小文件处理的针对性优化,导致访问海量小文件时效率低下。针对分布式文件系统中海量小文件访问时的数据服务器优化问题,提出了一种采用扁平式数据存储方法的轻量级文件系统FlatLFS,取代传统文件系统对上层分布式文件系统提供数据存储和访问支持,提高了数据服务器处理小数据块时的I/O性能,从而提升了整个分布式文件系统的性能。实验表明,当数据块大小设定为1M时,FlatLFS的随机读性能分别比ext3、ext4、reiserfs高135%、112%和122%。
