动基站时差探测系统定位方法研究

针对传统长基线时差探测系统的缺点,提出了全新的动基站时差测量系统并给出了目标的定位原理。在典型布站、信息存在冗余的前提下,通过子集选优法确定了最佳定位算法,并根据工程应用的需要确定了更加合理简捷的定位算法,统计仿真表明了该算法的有效性。最后,计算了目标高度测量精度并归纳了其特点,给出了有益的结论。     

图论及神经网络在地空导弹部队阵地中的应用

防空部队特别是地空导弹部队抗击敌空袭作战必须依托相应的阵地进行,而地空导弹部队阵地部署与选择的正确与否是地空导弹部队能否有效进行抗击敌空袭作战的一个重要因素,地空导弹部队阵地部署与选择需要综合考虑地形条貂件、机动条件、作战时间条件等各种因素.提出阵地部署与选择的几个指标,用图论与神经网络方法针对一个具体的例子对所提出的指标进行求解计算,得出阵地部署与选择的方案.     

基于三角模糊数的登陆点选择模型

针对登陆点选择的特点,对登陆点选择步骤进行分析,确定影响的四个基本因素,利用三角模糊数型多属性决策方法建立登陆点选择模型。与层次分析法相比,此算法时更能突出登陆点选择时,指挥者对登陆点的偏好所影响登陆点选择的基本因素值只能大概给出,基本因素之间的权重信息也不能完全确知的特点,通过计算机编程,此模型能够快速地实现对登陆点的排序选优,为指挥员提供辅助决策。     

The correlates of transatlantic burden sharing: revising the agenda for theoretical and policy analysis

While recent work has attempted to update the research agenda for transatiantic defense burden-sharing, there remain significant gaps between the public choice defense economics literature and the security studies literature. The presence of such a gap is unfortunate, because defense spending choices are likely shaped by factors identified by the public choice literature, as well as the strategic and cultural variables that the security studies literature tends to focus on, as well as domestic macroeconomic factors. The independent variables identified in recent qualitative literature are extremely useful analytically, and, fortunately, they have reasonable proxies in available quantitative data, which enables scholars to study them across large groups of countries and many years. This article builds upon such work to synthesize the most notable of the factors identified in the current literature, and offers some common analytical ground that will benefit both scholars and practitioners..     

Terrorist choice: a stochastic dominance and prospect theory analysis

The paper explores terrorist choice by applying two well-known theoretical frameworks: stochastic dominance and prospect theory (PT). We analyse each pair of attack methods that can be formed from the RAND-MIPT database and the Global Terrorism Database. Instances of stochastic dominance are identified. PT orderings are computed. Attention is accorded to the identification of ‘trigger points’ and the circumstances that may lead to an increased likelihood that a terrorist will select an attack method associated with a higher expected number of fatalities, i.e. a potentially more damaging attack method.     

从艺术客体的选择看中国古代戏剧家表现社会生活内容的广阔性

中国古代戏剧家在戏剧人物艺术客体的选择上,同古希腊悲喜剧和印度梵剧迥然不同,表现出别具一格的建树和开拓性,初步形成了具有中国作风和中国气派的戏剧文化,并在这种戏剧文化中体现了中国古代剧作家们主体精神的独立不羁的自由品格和表现社会生活内容的无限广阔性。     

THE CASE FOR DEFENCE

What is the case for defence and is it a worthwhile investment? This question is addressed for two contrasting nations, namely, the UK and New Zealand. Economists have a set of standard analytical tools for addressing the question but they are difficult to operationalise. This paper provides policy‐relevant answers.     

一类不确定语言型机降场选择模型

机降场选择是超视距垂直登陆作战的关键工作之一。针对机降场选择的决策特点,定义了不确定语言集结算子,建立了基于不确定语言型多属性群决策方法的机降场选择评估模型。该模型直观、简单,降低了对指挥员的专业素质要求,有效弥补了指挥员的主观判断误差,提高了评估决策可靠性,具有较高的应用价值。     

特色创建:学校文化建构的主动选择——以三师一中“全面发展,军事见长”的学校特色创建实践为例

学校改革的核心动力来自于学校文化的变革。学校文化的建构为学校特色创建提供了生存的土壤和发展的动力,学校特色建设的理性诉求又是学校文化建构的主动选择。本文从学校文化思考出发,梳理学校特色创建的文化定位、背景考量、原则与策略,并以三师一中特色创建的实践尝试为例,论述特色创建是文化建构的主动选择和学校变革发展的突破口。     

The political economy of drones

This paper provides a political economy analysis of the evolution of unmanned aerial vehicles (UAV), or ‘drones’ in the USA. Focus is placed on the interplay between the polity and private economic influences, and their impact on the trajectory of political, economic, and military outcomes. We identify the initial formation of the drone industry, trace how the initial relationships between the military and the private sector expanded over time, and discuss present relationships. Understanding the historical evolution of UAV technology, as well as the major players in the industry today, is important for ongoing policy debates regarding the use of drones both domestically and internationally.
