论日伪言说下的新四军——对铁军精神的反证式解读

中国共产党领导下的新四军在8年抗战中做出了巨大的牺牲和贡献,日伪虽然对此百般掩饰与歪曲,但在论及新四军的作战地区、新四军的战术与作战、新四军的素质及其与群众的关系时仍透露一些无法掩盖的事实。从某种程度上,这些事实反而成为新四军铁军精神的一种反面证明。     

武器系统的可靠性评估方法研究

武器系统的可靠性是武器装备研究的重要内容,而评估可靠性的方法又是可靠性研究的关键,本文尝试对武器系统可靠性的评估方法进行了探讨。     

基于引导员负荷的指挥引导容量评估

针对目前传统指挥引导容量评估不准确的问题,通过对空战指挥引导容量与引导员负荷的综合分析,提出了基于引导员负荷的指挥引导容量评估方法。基于引导员负荷重新定义了指挥引导容量,给出了引导员负荷的确定方法,并建立了指挥引导容量评估模型。最后对某指挥机构进行实例评估,评估结果表明所提出的指挥引导容量评估方法将评估误差控制在1批之内。     

SVM在空中目标威胁值评估中的应用

构建了基于回归型支持向量机的空中目标威胁值评估模型,确定了基于粗糙集理论的空中目标威胁因素,并建立了数据离散化、归一化的标准。将常用的4种核函数应用于对空中目标威胁值的估计,并通过基于网格法和遗传算法的搜索方法找到模型的最优参数。最后通过Matlab对算例进行了仿真验证。     

基于同心筒结构的共架发射系统武器发射空域协调方法

为保证舰艇和武器系统安全,针对多武器共架发射时的发射协调问题,提出了空域协调的方法。首先,定义了空域协调的概念,分析了燃气排导、初始飞行弹道交叉对空域协调的影响;然后,通过判断发射活动、隔舱距离排序、隔舱属性赋值、判断隔舱相邻及弹道交叉等影响因素提出了空域协调的具体步骤;最后,对空域协调方法进行了算例验证。结果表明:通过空域上合理地选择武器(弹位)可以有效避免共架武器发射时产生干涉,保证系统安全。该方法对解决多类型舰载武器发射协调问题有借鉴意义。     

ESD EMP能量耦合线性化建模

针对利用非线性建模方法研究静电放电电磁脉冲(Electro Static Discharge Electro Magnetic Pulse,ESD EMP)能量耦合存在计算复杂、模型收敛性能较差的问题,基于ESD辐照实验提出了一种非线性系统线性化建模方法。该方法是将系统响应与激励间的非线性关系转化为线性关系后,利用带遗忘因子的递推最小二乘法进行线性回归来建立模型。首先利用3.5 k V ESD实验数据进行建模,然后应用3.5 kV、4.5 kV ESD实验数据进行模型验证,2种情况下的拟合度均达到94.303 3%。结果表明:线性化建模能有效降低建模难度,且模型精度较高,为ESD能量耦合研究提供了一种简便有效的建模方法。     

Advancing “Defence-in-depth”: intelligence and systems dynamics

This article aims to encourage the fostering of more systems thinking, and its greater exploitation, within the domain of contemporary intelligence. With particular focus on “micro systems thinking” and with reference to key intelligence processes, such as intelligence analysis, the utility of many systems dynamics within the intelligence context seeks to be further revealed. Through their greater collective harnessing, including up to “System of Systems” (“SoS”) dynamics, and promoting all that they can offer, more sophisticated overarching operational-to-strategic/policy “ends,” notably that of “defence-in-depth,” can be viably further advanced in a sustainable manner into the future. Arguably, a much-needed transformative impact on contemporary intelligence can also be increasingly realised through comprehensively engaging in and with more systems and SoS thinking. Aiding civil protection tasks, crisis management, emergency planners, and civil contingency practitioners likewise gain.     

Military Innovation and Tactical Adaptation in the Israel–Hizballah Conflict: The Institutionalization of Lesson-Learning in the IDF

This article highlights a pattern of military adaptation and tactical problem-solving utilized by the Israel Defense Forces (IDF) while engaged in protracted conflict with the Lebanese militant group Hizballah. It discusses the IDF’s recent attempts to institutionalize their historically intuitive process of ad-hoc learning by developing a formal tactical-level mechanism for ‘knowledge management’. The diffusion of this battlefield lesson-learning system that originated at lower-levels of the organization is examined, as well as its implementation and effectiveness during the 2006 Lebanon War. A nuanced analysis of IDF adaptation illustrates the dynamic interplay between both ‘top-down’ and ‘bottom-up’ processes of military innovation.
