自由曲面逆向工程中的区域性再设计方法

针对自由曲面逆向工程的再设计,提出了区域性再设计方法。此方法的思想是通过调整1个控制点,使得一定区域内的多个控制点按照某种规律随之变化,从而可以实现曲面再设计的要求。基于此思想,给出了区域性再设计方法的理论推导,并进行了实例仿真验证。

空天环境对作战效能的影响——基于云模型的评估方法

空天环境作为传统战场空间的拓展,是打赢信息化战争、维护国家安全的重要战略高点。为更好了解空天环境对作战效能的影响,运用云模型的评估方法,从自然环境、作战平台、武器装备等方面对空天环境进行研究,以期对空天作战发展方向提供参考。研究表明,应根据空天作战时自然环境对作战的影响权重,增强空天作战平台与新概念武器自主适应环境的能力。     

韩国反导政策:调整、原因及影响

韩国自20世纪90年代起开始考虑反导系统的构建以来,其反导政策经历了"明确反对加入美国反导体系,自主构建韩国型导弹防御系统"到"强化韩美、韩美日反导合作,谋求实质上融入美国反导体系"的显著调整与变化。韩国反导政策的演变与朝鲜核、导威胁的与日俱增、韩国自身反导能力的不足及美国的极力推动等因素密不可分。当前,韩国开始部署"萨德"末段高空区域反导系统,韩美反导合作日益深入,并向韩美日三边合作拓展,且取得了实质性的进展。韩国强化与美、日的反导联合,在军事、外交、安全方面引发了广泛影响。

基于知识图谱和二级传播理论的网络舆情事件传播分析

在目前的网络舆情事件传播分析中,尽管生命周期模型能够较好地描述舆情事件的发展规律,但却忽略了部分时期之间存在的共性特征,无法充分体现意见领袖对网络舆情事件传播过程的影响。本文提出了一种基于知识图谱和二级传播理论的网络舆情事件传播分析方法,首先,构建网络舆情事件知识图谱;然后,基于知识图谱计算用户影响力挖掘意见领袖;最后,考虑到意见领袖的重要地位,为有效刻画网络舆情传播规律、周期与途径,根据传播学二级传播理论构建网络舆情事件传播模型,将生命周期模型的五个时期按照舆情发展态势划分为三个阶段：潜伏期（爆发期阶段）、爆发期（成熟期阶段）以及成熟期和衰退期（消亡期阶段）。实验结果表明,该方法能够有效计算和发掘包括意见领袖在内的用户影响力,传播、分析网络舆情事件效果较好。     

基于灰色关联分析的装甲装备人因故障影响因素研究

根据装甲装备在试验和使用中人因故障发生的原因,将人因故障影响因素分为设计因素、维修因素、使用因素、人体机能因素、人机界面因素和环境因素6类,采用灰色关联分析法对其进行辨识分析,发现造成装甲装备人因故障率从高到低的因素依次为：维修因素、使用因素、人机界面因素、设计因素、环境因素和人体机能因素,该研究结果可为装甲装备综合管理和设计提供理论依据。     

基于影响网络与不完全信息多阶段博弈的作战行动序列模型及求解方法

拟制作战计划的关键是生成作战行动序列.考虑作战行动过程中的不确定性以及激烈对抗性,以影响网络分析作战行动和战场态势之间的相互影响,用不完全信息博弈分析敌对双方之间的对抗,建立了基于影响网络和不完全信息多阶段博弈的作战行动序列模型,并给出了求解方法.通过计算实例说明了模型及其求解方法.结果显示该模型生成的COA更适应于对抗环境.     

THE ‘PRICE’ OF TERRORISM

Security measures are said to increase the price of terrorism. This price has not been hitherto defined in an economically meaningful way. This paper provides a precise definition by treating the terrorists’ resource endowment as a parcel of contingent claims to political influence with a price equal to the summed value of those contingent claims in potential states of the world. Equipped with this definition, an equilibrium model of the price of terrorism is deployed. Important insights are gained into the effect of terrorists’ risk aversion at the level of the price of terrorism in different states of the world and the theoretical conclusion is reached that higher security is associated with a lower price of terrorism rather than a higher price. The implications for policy are discussed.     

Influence without power? Reframing British concepts of military intervention after 10 years of counterinsurgency

British attitudes towards military intervention following the campaigns in Iraq and Afghanistan have undergone what appears to be considerable change. Parliament has voted against the use of Britain's armed forces in Syria and the public are unenthused by overseas engagement. Conscious of the costs and the challenges posed by the use of British military power the government has been busy revamping the way it approaches crises overseas. The result is a set of policies that apparently heralds a new direction in foreign policy. This new direction is encapsulated in the Building Stability Overseas Strategy (BSOS) and the more recent International Defence Engagement Strategy (IDES). Both BSOS and IDES set out the basis for avoiding major deployments to overseas conflict and instead refocuses effort on defence diplomacy, working with and through overseas governments and partners, early warning, pre-conflict prevention and post-conflict reconstruction. Developing a number of themes that reach from across the Cold War to more contemporary discussions of British strategy, the goal of this special edition is to take into account a number of perspectives that place BSOS and IDES in their historical and strategic context. These papers suggest that using defence diplomacy is and will remain an extremely imprecise lever that needs to be carefully managed if it is to remain a democratically accountable tool of foreign policy.
