基于灰色关联分析的防空兵力编组方案优选

要地防空中需要研究的问题很多，其中要地防空兵力编组方案优选是研究的重点问题之一，首先对灰关联分析方法和要地防空兵力编组的关联性进行了分析，然后在兵力部署要求的基础上，建立了评价指标体系及其量化分析，最后采用灰关联分析方法建立了方案优选模型，具体的实例验证了基于灰关联分析的兵力编组优选模型的可行性和有效性，为要地防空兵力编组方案的优选问题提供了一种量化的新思路。     

A usable past: a contemporary approach to history for the Western profession of arms

The most effective way for the Western profession of arms to use history is to disavow the purism and narrow specialisation of today’s academia in favour of developing a contemporary approach to the subject. The latter aims to foster a range of applied diagnostic skills that transcend the temporal dimensions of past, present, and future. A contemporary approach to history for military professionals emphasises the use of inter-disciplinary war studies to enhance policy relevance. In any defense and security organisation, history must be usable in the sense of providing cognitive and interpretative skills for probing relationships between possibility and actuality, between experience and expectation, and between singularity and repetition. Using history to examine such dialectical interconnections is particularly valuable when military establishments confront their essential task of analyzing emerging trends in the future of war.     

图像质量主客观评价的相关性分析

图像质量的客观评价与人类主观感知之间一定存在必然的联系,并且这些客观评价方法应该取代主观评价。也就是说,这些客观评价方法允许在不征求任何用户意见的基础上,去评价一个给定系统的性能。本文研究了在变化的压缩体制下实施在若干图像上的一套客观测量和主观评价之间的相互关系,并给出了初步的分析结果。     

强背景噪声下电晕放电辐射信号小波阈值去噪和分析

分析电晕放电信号小波阈值去噪中小波基函数的最优选取、分解层数及阈值的确定,并对实测电晕放电信号进行小波阈值去噪。结果表明,选取db8小波作为最优小波基函数,选取双变量阈值函数作为小波阈值函数对电晕放电信号进行小波阈值去噪,放电辐射信号与背景噪声可以得到有效分离,具有很好的去噪效果。     

Operations planning revisited: theoretical and practical implications of methodology

Parts of NATO’s contemporary planning framework called the comprehensive operations planning directive (COPD), and parts of the operation-level planning process should be revised since they suffer from methodological inconsistency. This claim is defended by discussing contradicting methodological properties and heuristics applied when framing and managing a military problem in accordance with the COPD. The methodological inconsistency within the COPD; in other words, simultaneously applying contradictory methodological properties, implies one theoretical and three practical implications. The theoretical implication is summarised in a meta-theoretical framework and explained by discussing five methodological properties: non-linearity, emergence, independently changeable generalisations, invariance and boundaries. The three practical implications of methodology imply that methodology is guiding: the problem-frame, conceptual development and action. To improve military planners’ understanding and management of these four identified implications, NATO is recommended to develop a “handbook of methodology.” The purpose of such a handbook should be to emphasise the utility of methodology when planning military operations.
