伴随着经济学的发展,经济分析方法于上世纪被引入法学领域,形成法经济学。经过半个世纪的努力,经济分析方法已经出现在众多部门法学研究中。军事法作为一门独立的部门法学并不排斥经济分析方法,用经济分析方法研究军事法具有重要意义。 相似文献

针对遥测振动信号冲击强、响应周期短、共振频带宽和小样本等特点导致异类模式识别率低的问题,提出基于参照化流形空间融合学习的敏感特征提取与异常检测方法。采用多尺度分析方法将信号正交无遗漏地分解到各尺度带中,提取多尺度特征构造高维特征集;以相同的正常信号样本结合相同类型的异常样本建立专属参照化模型单元,采用线性流形学习获取各参照化模型单元多尺度流形特征差异,增强异常特征的敏感性。融合各参照化模型单元的投影矩阵对原始特征集进行升维再学习,获取低维多尺度敏感流形特征;输入到分类器实现对未知样本状态辨识。实测信号处理结果验证了算法的有效性。 相似文献

对雷达探测来说,如何有效地增强真实目标回波信号、提高信噪比水平是非常重要的。传统的降噪方法如平滑滤波、傅立叶降噪很难有效地降低与目标频谱相重叠的噪声。空域相关滤波算法是小波滤波算法中的一种,能够有效地解决这个问题。该算法是利用真实信号与噪声在尺度间的不同表现来实现的,能够在保留信号细节的同时,有效地降低噪声。仿真表明,该算法在雷达回波的降噪中取得了较好效果,有效地降低了噪声。 相似文献

随着工艺尺寸的逐渐缩小,集成电路中由放射性粒子引起的软错误不断增加,在设计时必须考虑由软错误引起的可靠性问题.使用软错误免疫寄存器对电路敏感部分选择性加固是降低逻辑电路软错误率简单有效的方法.总结了常用的软错误免疫寄存器结构,并使用可靠性分析方法对8种寄存器进行量化研究和比较,得出双模时空冗余寄存器具有更高的可靠度;针对现有可靠寄存器开销较大的缺点,设计了一种基于时钟延时的动态主级时空双模冗余寄存器--DMTS-DR,不仅能很好地免疫自身的SEU,还能对前级组合逻辑的SET进行有效屏蔽.与其它可靠寄存器相比,DMTS-DR的面积和延时开销都有大幅降低,在可靠性、面积和速度间实现了较好的折中. 相似文献

This article investigates the demand for military expenditure for a sample of key Asia-Pacific countries. Spatial panel demand estimates are presented for three joined spatial units using a fixed-coefficient spatial lag model based on a two-step efficient GMM estimator. Spatial autoregression estimates are next presented for 1991–2015, founded on alternative kinds of country connectivities, such as contiguity, inverse distance, discrete distance, and power-projection considerations. Finally, 11 select countries’ demands for defense equations are estimated using seemingly unrelated regressions. From alternative perspectives, these estimated models indicate how Asia-Pacific countries respond to the defense spending of other countries. In the spatial runs, free riding is prevalent despite the growing military might of China, which apparently is not generally viewed as a threat. For the sample period, the projection of Chinese or American power is a relevant spatial factor. The main threat is reflected in non-U.S. allies’ reaction to U.S. allies’ defense spending during 1991–2015 and to Chinese defense spending after 2002. 相似文献

This article offers a comprehensive analysis of the database ‘Mémoire des hommes’, which is a record of more than 1 million French soldiers officially recognized as dead during the World War I (WWI). Integrating this source with the 1911 census, we evaluate the potential numbers of recruits by French regional department. From this, a model identifies the factors affecting the number of deaths. While demographic factors are the principal determinants, adding significant economic, political and spatial factors reduces the unexplained variance between regions and significantly improves the explanation of the disparity in the number of deaths by region. 相似文献
