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.     

The British army,information management and the First World War revolution in military affairs

Information Management (IM) – the systematic ordering, processing and channelling of information within organisations – forms a critical component of modern military command and control systems. As a subject of scholarly enquiry, however, the history of military IM has been relatively poorly served. Employing new and under-utilised archival sources, this article takes the British Expeditionary Force (BEF) of the First World War as its case study and assesses the extent to which its IM system contributed to the emergence of the modern battlefield in 1918. It argues that the demands of fighting a modern war resulted in a general, but not universal, improvement in the BEF’s IM techniques, which in turn laid the groundwork, albeit in embryonic form, for the IM systems of modern armies.     

基于模糊自适应变维Kalman滤波器的跟踪算法(英文)

针对不同阶数的Kalman滤波器具有不同的跟踪能力与跟踪效率之间存在的矛盾,设计了一种模糊自适应变维跟踪算法(FAVD)。该算法使用两级滤波器,根据目标机动性的变化,适当地调整滤波器的阶数,使跟踪结果快速收敛,很好地解决了矛盾。同时通过模糊推理机制,在线调节高阶滤波器的参数,使适用范围大大增强,提高自适应能力,从而使该算法可以采用较少的模型覆盖较多的目标运动模式,达到很好的跟踪滤波效果,计算量也会大大减小。通过对计算机仿真结果分析表明,提出的算法具有可靠、计算简便、快速等特点,模型滤波精度较高,并可实现实时跟踪预测,具有一定的理论价值和实用价值。

基于RNN汉语语言模型自适应算法研究

深度学习在自然语言处理中的应用越来越广泛。相比于传统的n-gram统计语言模型,循环神经网络(Recurrent Neural Network,RNN)建模技术在语言模型建模方面表现出了极大的优越性,逐渐在语音识别、机器翻译等领域中得到应用。然而,目前RNN语言模型的训练大多是离线的,对于不同的语音识别任务,训练语料与识别任务之间存在着语言差异,使语音识别系统的识别率受到影响。在采用RNN建模技术训练汉语语言模型的同时,提出一种在线RNN模型自适应(self-adaption)算法,将语音信号初步识别结果作为语料继续训练模型,使自适应后的RNN模型与识别任务之间获得最大程度的匹配。实验结果表明:自适应模型有效地减少了语言模型与识别任务之间的语言差异,对汉语词混淆网络进行重打分后,系统识别率得到进一步提升,并在实际汉语语音识别系统中得到了验证。     

ITSON：一种基于拓扑演化的P2P智能搜索机制

P2P系统中节点的动态特性对搜索性能的稳定提出了很大挑战。借鉴社会学和组织学相应原理,提出拓扑演化模型捕获节点的运动规律。节点模拟人类在社会网络中的行为,根据自身和他人的兴趣变化,随搜索过程的进行,利用自身局部信息,动态、自适应地调整网络拓扑,及时反映资源分布以及搜索内容的动态变化,维持资源合理组织。在此基础上提出的智能搜索机制ITSON(InTelligent Search based on tOpology evolutioN),利用消息转发的智能性进行路由方向决策,从而迅速定位资源提供节点。仿真结果说明,ITSON能自动优化网络,具有良好的搜索性能和自适应特性。     

Communication: Wrap‐up on the cost of the gulf war

This paper discusses how crises and war may “disrupt” company activities, and how companies adapt to these disruptions. Croatia is used as a case study. The original hypothesis was that war led to breaks in physical flows: in other words, that companies experienced difficulties in importing and obtaining supplies of goods. Instead, it appears that loss of customers and severely worsened conditions of payment were the principal problems for Croatian companies. Although it does not fall within the scope of this investigation, it is interesting to note that the Croatian government has not imposed any direct rationing on the industrial sector, but rather via the banking system.
