Buy now,pay later: American military intervention and the strategic cost paradox

This paper explores the notion that US efforts to evade the political costs of war paradoxically contribute to the subsequent exacerbation of costs over time. Leaders seek to purchase political capital in the short term by limiting the costs and requirements of military operations, but in doing so cause strategic and political liabilities to mount in the long run. While identification of such behaviour is not new, insufficient attention has been devoted to explaining its causes, dynamics, and manifestations in relation to key decisions on and in war. Evidence derived from studies of recent American discretionary campaigns is analysed to advance an argument with respect to this pattern of self-defeating strategic behaviour.

参数化时频分析的匀加速旋转目标ISAR成像

对于机动目标,运动补偿后目标相对于雷达的转动不能近似为匀速转动,而是更接近于匀加速转动,此时传统的距离多普勒成像算法不能得到很好的成像结果.分析总结了几种针对非匀速转动的时频联合分析算法,提出了一种基于参数化时频分析-AGCD快速算法的匀加速旋转目标成像算法,仿真表明了该算法具有精度高、速度快且无交叉项的优点,比原有的一些算法有较大的改进.     

影响图建模算法的改进

影响图建模方法是一种规范化的复杂系统建模方法,其实质是将表征复杂系统的参量及参量间的耦合关系进行分类,并以此为基础建立系统的数学模型.影响图建模算法就是将系统的参量及参量间的耦合关系进行分类的算法.目前使用的算法是James R.Burns于1979年提出的.该算法仅考虑了最小的反馈回路,而没有考虑影响图中存在的一般反馈回路,且一些操作造成了不必要的循环.在分析该算法的基础上,考虑了一般的反馈回路,并对原算法的操作步骤进行了优化重组.     

Estimation from binomial data with classifiers of known and unknown imperfections

Observations from inspection by a “test” method and a standard method are combined to provide estimators of population proportion, and of probabilities of misclassification for the test method. Results of Hochberg and Tenenbein [3] and of Albers and Veldman [1] are extended to the case where the standard method is not perfect, but its misclassification probabilities have known values. Both moment and maximum-likelihood estimators are considered and some asymptotic properties of the resulting estimators are compared.     

The orienteering problem

Orienteering is a sport in which start and end points are specified along with other locations. These other locations have associated scores. Competitors seek to visit, in a fixed amount of time, a subset of these locations on the way from the start point to the end point in order to maximize the total score. An effective center-of-gravity heuristic is presented that outperforms heuristics from the literature.     

What is the global landpower network and what value might it provide?

US national security guidance, as well as the US Army’s operational experiences since 2001, emphasizes the importance of working closely with partner countries to achieve US strategic objectives. The US Army has introduced the global landpower network (GLN) concept as a means to integrate, sustain and advance the Army’s considerable ongoing efforts to meet US national security guidance. This study develops the GLN concept further, and addresses three questions. What benefits can the GLN provide the Army? What are the essential components of the GLN? What options exist for implementing the GLN concept? By developing the GLN concept, the Army has the opportunity to transition the GLN from an often ad hoc and reactive set of relationships to one that the Army more self-consciously prioritizes and leverages as a resource to meet US strategic objectives.
