一种非对称鲁棒性盲水印算法

针对数字图像版权保护,提出一种非对称鲁棒性盲数字水印方法。通过将水印嵌入到最少受图像改变影响的子空间,使嵌入水印具有鲁棒性,且通过对特征子空间的选取限制,使算法具有较高的检测概率和安全性以及较低的虚警概率。同时,水印嵌入矩阵与提取矩阵不同,它可公开除密钥外的所有其它的信息,而且能实现水印盲提取。实验结果证明了该算法的鲁棒性。     

连续信息空间中的信息泄漏问题研究

在联邦式作战仿真平台中,互相通信的主体在进行通信的同时还需要保护其私有的信息。讨论了基于线性方程组“无穷解”条件下的连续信息空间的信息泄漏和保护问题,包括该模型的基本特性和防止泄漏的方法,指出了存在信息的部分泄漏问题,并给出了检测部分泄漏的方法,为提高计算性能,可指定检测子空间,最后,讨论了信息动态改变对信息泄漏的影响。     

电子战对地空导弹拦截行动影响分析

基于地空导弹(红方)对空中编队(蓝方)的拦截过程中的薄弱环节以及蓝方对红方实施的电子战措施的分析,对蓝方实施的电子战对红方拦截行动的影响进行了定量评估,得出蓝方突防概率与电子战综合作战效能之间的函数关系。仿真结果表明,对地空导弹拦截的每一环节都可以有效地实施电子战,削弱地空导弹的拦截能力。     

Terrorism as Method in Nepali Maoist Insurgency, 1996–2016

During the period 1996–2006, the Communist Party of Nepal (Maoist) waged overt people’s war to seize state power and institute a new order that realized the party’s understanding of ‘New Democracy’ as posited by Mao Tse-tung. Contextual shifts led to a crucial strategic turning point in September 2005, when the Maoists agreed to a united front with estranged legal parties to oust the monarchy and establish a republic. Though touted as acceptance of political reintegration, the move was tactical rather than strategic. The party had no intention of supporting a parliamentary version of democracy and thus, 2006–2016, engaged in a covert effort to seize power. Central to this effort was the paramilitary Young Communist League (YCL), the members of which responded to inflammatory party verbiage and exhortations with attacks upon rival political actors. These attacks, academically and legally, were terrorism and offered a salient illustration of intra-state unrestricted warfare. Ultimately, organizational, national, and regional circumstances caused the main Maoist movement to move decisively away from its covert approach. By that time, however, radical splinters had embraced the use of terrorism against rival political actors, creating a situation whereby local politics is yet a dangerous endeavor in certain areas and at certain times.     

基于贝叶斯网络的作战目标评估

在作战指挥决策活动的筹划阶段,对敌体系要害和关键点的分析,当前尚未形成系统方法。针对此问题,利用贝叶斯网络在非精确知识表达与推理领域的优势,提出了综合考虑目标价值、打击难度、打击效果等因素的作战目标评估模型。根据判别贝叶斯网络分类器性能优于生成贝叶斯网络分类器的特点,在经相关领域专家论证的样本数据集的基础上,采取梯度下降法训练得出评估模型各结点条件概率分布。最后,利用Netica仿真软件,经样本数据测试,证明了作战目标评估模型的合理性。     

电子战飞机远距支援干扰阵位配置建模与仿真

针对电子战飞机远距支援干扰新体制雷达阵位配置问题进行研究。首先是对电子战飞机干扰效能量化分析,从俯仰和方位两个方面对干扰覆盖范围进行建模仿真。基于干扰统一方程,建立干扰阵位配置优化模型,包括阵位配置区域和阵位配置高度模型,并给出了干扰阵位配置参数的具体计算方法。最后,通过仿真实例验证模型的有效性,结果表明该模型对于电子战飞机阵位配置有一定的指导意义。     

应用新型Lanchester方程的非对称空战进程预测

针对未来空战中可能出现的非对称空战问题进行研究,在设定的非对称空战背景下构建新型Lanchester方程对问题进行建模分析,得到单一机种和多兵种非对称空战模型,并通过仿真试验验证了模型的有效性,对非对称空战指挥决策提供了一定的帮助。     

The fertile ground of Hell’s carnival: Charles T. R. Bohannan and the US Army’s Counter Intelligence Corps’ investigations of war criminals,collaborators, and the Huk,in the Philippines 1945–1947

Insurgencies thrive in regions where government legitimacy is absent. In the post-war Philippines, Captain Charles T. R. Bohannan of the Army’s Counter Intelligence Corps became actively aware of this dynamic. Bohannan is best known for his later work with Edward Lansdale and Ramon Magsaysay in defeating the Huk Rebellion (1950–1954). Here the author examines Bohannan’s early investigative work against Japanese war criminals, wartime Filipino collaborators, and the rising threat of communist subversion most associated with the Huk. All of these experiences fed into what would be the successful campaign against the Huk, chronicled in his seminal work, Counter Guerrilla Operations: The Philippines Experience, and offers lessons on the investigative (as opposed to tactical or psychological) nature of effective counter-insurgency work, as it relates to both legitimacy in governance and the rise of insurgencies.     

Putin – the masked nemesis of the strategy of ambiguity

Recent events demonstrate the complex and adaptive approach employed by Russia to reassert influence in Europe. The changing face of Russia’s strategy commenced in 2007 when it launched a crippling cyber-attack against Estonia. This was followed by a large Russian conventional attack against Georgia in 2008, occupying two large areas of the nation. 2014 witnessed the Russian annexation of Crimea where in just a week, Russia seized control of Crimea “without firing a shot.” The annexation of Crimea was rapidly followed by a Russian inspired and led subversive war in eastern Ukraine. The common thread among these diverse Russian operations is its use of ambiguity to confound and confuse decision makers in the West.
