A historical overview of US counter-insurgency

Say not the struggle naught availeth,

The labour and the wounds are vain,

The enemy faints not, nor faileth,

And as things have been, things remain.

Myth and the small war tradition: Reassessing the discourse of British counter-insurgency

In recent years a number of commentators have posited that the British reputation for conducting small wars has suffered in the wake of setbacks in Iraq and Afghanistan. The argument here contests whether such a tradition can be truly said to have ever existed. A close examination of this supposed tradition reveals it to be a myth. In fact, rarely have the British armed forces claimed a facility for counter-insurgency or small war. Invariably, commentators outside the Army have ascribed the tradition to them. Most notably, commentators in the United States keen to discern practices of minimum force or rapid institutional learning generated the narrative of British COIN expertise. Ultimately, what this myth reveals is that, when deconstructed, it is political will, not an ingrained understanding of fighting insurgencies, that has determined Britain's success, or otherwise, in so-called small wars.     

基于数据场的登陆作战体系兵力编组效能分析?

兵力编组效能直接影响登陆作战体系的作战能力。在分析梯队式和群队式兵力编组模式下登陆作战体系网络模型的基础上,利用数据场理论研究登陆作战体系的拓扑势场,描述梯队或群队间由支援、协同产生的协同作战能力,建立基于数据场的登陆作战体系兵力编组效能模型,并进行仿真分析。得到了一种定量分析兵力编组作战效能的方法。

25nm鱼鳍型场效应晶体管中单粒子瞬态的工艺参数相关性

基于TCAD(Technology Computer-Aided Design)3-D模拟,研究了25 nm鱼鳍型场效应晶体管(Fin Field Effect Transistor,FinFET)中单粒子瞬态效应的工艺参数相关性。研究表明一些重要工艺参数的起伏会对电荷收集产生显著影响,从而影响到电路中传播的SET(Single Event Transient)脉冲宽度。对于最佳工艺拐角,离子轰击后收集的电荷量可以降低约38%,而在最坏工艺拐角下,收集的电荷量则会增加79%。这些结论对FinFET工艺下的SET减缓及抗辐射加固设计提供了一种新的思路。     

碳纳米管场效应管尺寸缩小特性的比较

由于具有更为显著的量子隧穿效应,碳纳米管场效应管具有较硅基MOS管不同的尺寸缩小特性,同时,由于工作机理的不同,类MOS碳纳米管场效应管(C-CNFETs:Conventional MOS-like Carbon Nanotube Field Effect Transistors)的尺寸缩小特性与隧穿碳纳米管场效应管(...     

Keep the change: Counterinsurgency,Iraq, and historical understanding

This article explores the historical reasoning behind counterinsurgency thinking, particularly as applied to Iraq, using Douglas Porch's book, Counterinsurgency: Exposing the Myths of the New Way of War as a reference point. It argues that the classic historical analogies of counterinsurgency theory were inapt in dealing with the conflict in Iraq, and that the historical reasoning behind counterinsurgency more generally deserves greater scrutiny. Not only are the analogies of questionable applicability, but the evidence of causation in prior conflicts is ultimately unproveable. In the end, Counterinsurgency theory and the US Army's Field Manual 3-24 on Counterinsurgency were politically useful during the ‘Surge’, beginning in 2007, but remain intellectually and historically problematic.
