Reconciling strategic studies … with itself: a common framework for choosing among strategies

Three distinct, and seemingly irreconcilable, schools of thought are identified within the strategic studies literature. One which searches for “universal principles of war,” a second, “context-dependent,” approach that seeks to embed each instance of warfare within its concurrent social, political, technological milieu and, finally a “paradoxical logic” school, which equates strategy with the generation of uncertainty. The author offers some intuitive concepts from non-cooperative game theory to develop a “dominate-mix” approach to strategy choice. In doing so, he helps to reconcile these disparate approaches and provides a simple framework to assist researchers in framing military decisions as well as to assist planners in choosing among strategies.     

混合尺寸目标电磁计算的时域伪谱/有限体积混合方法

针对单一算法对混合尺寸目标进行时域电磁分析的困难,提出一种时域伪谱(PSTD)同时域有限体积(FVTD)混合方法。FVTD可方便地分析复杂的几何结构和材料,但是难以计算电大尺寸的目标,PSTD则特别适合计算电大尺寸的规则结构,但在模拟复杂的几何结构尤其是带有曲边结构以及电大、电小共存结构时存在困难。混合方法克服了单独算法的缺点,融合各自的优势,提高了算法的求解能力和应用范围。为了减小两种算法连接边界带来的反射,采用了FVTD计算面均值的二次函数重构方法,给出了交叠网格和非交叠网格两种混合方案。数值试验表明,混合方法有较高的精度,具有时域分析混合尺寸目标电磁问题的能力。

North European security after the Ukraine conflict†

Russia’s illegal occupation and annexation of the Crimean peninsula in February–March 2014, and the country’s well-documented involvement in the separatist conflict in Eastern Ukraine, have led to a significant worsening of Russia’s relations with the West. Vladimir Putin’s move to redraw Russia’s southern borders through the use of military force and subversive measures has given rise to an uncertainty that goes well beyond the post-Soviet space. Since 2014, North Atlantic Treaty Organization (NATO) has had to reassess many aspects of its relationship with Russia. The alliance has also initiated various measures to strengthen the military security of its eastern member states, particularly the Baltic states, Poland, and Romania. Further to the North, NATO’s northernmost member – Norway – is following developments in Russia with a heightened sense of awareness. The same goes for non-aligned Sweden and Finland, which are trying to adapt to the emerging, and increasingly complex, security environment in Northern Europe.
