军机驾驶员通讯用语语音信号及其清晰度影响因素分析

建立了军机驾驶员通讯用语词汇库及与故障相关的通讯用语词汇库,并对其中的主要词汇进行了汉语语音语谱分析。对影响军机驾驶员语音清晰度(可懂度)的有关因素——喉头送话器、座舱噪声、塔台录音进行了较详细的分析,得出主要影响因素为喉头送话器和座舱噪声,指出应改进送话器的方向且不能采用常规的固定参数滤波器来滤除座舱噪声。     

特种车辆乘载员生理监测与调节系统

特种车辆乘栽员的生理心理状态与车辆技术状态并列成为影响车辆整体效能的重要因素。针对乘栽员的生理心理状态进行监测并适时干预,可以实时掌握并调整人员状态。既有利于车辆能力发挥,也有利于整体协调。生理监测调节系统拟采用生物传感技术,采集人员生理心理指标参数,通过车辆通信及指控系统网络,使指挥人员能够及时掌握人员的疲劳及生命体征状态．通过合理的心理干预及医疗指导。使人员保持良好的心理生理状态或合理的医疗自救互救,最大程度地保存行动能力。该系统可应用于平时训练及评估．也可应用于行动决策指挥及医疗救护部署。

Reconciling strategic studies … with itself: a common framework for choosing among strategies

Three distinct, and seemingly irreconcilable, schools of thought are identified within the strategic studies literature. One which searches for “universal principles of war,” a second, “context-dependent,” approach that seeks to embed each instance of warfare within its concurrent social, political, technological milieu and, finally a “paradoxical logic” school, which equates strategy with the generation of uncertainty. The author offers some intuitive concepts from non-cooperative game theory to develop a “dominate-mix” approach to strategy choice. In doing so, he helps to reconcile these disparate approaches and provides a simple framework to assist researchers in framing military decisions as well as to assist planners in choosing among strategies.     

爱民固边的战略思维论要

爱民固边战略是＂十一五＂时期公安边防部队在建设社会主义和谐社会中的一项重大战略部署。＂十二五＂时期,形势任务更加严峻,必须进一步找准爱民固边是促进边境经济社会发展的新型人民战争的战略定位,完善以战略目的、战略原则、战略力量、战略措施为主要内容的战略架构体系,有效探索＂爱民—固边—发展—固边—利民＂的战略路线图,突出＂维稳主导、服务民生、强基固本、多元联动＂等战略重点,坚持＂并轨发展、标本兼治、无缝对接＂基本战略路径,使爱民固边战略更加系统化、规范化,纵深推进,打造公安边防特有品牌,不断产生更大的政治社会价值。     

关于移动消防通信指挥系统建设的几点思考

移动消防通信指挥中心的现代化程度和高科技应用水平已经成为建设一支现代化、信息化消防队伍的重要标志之一。移动消防通信指挥系统能够将消防部队灭火救援指挥工作进行优化和程序化、规范化,实现以信息平台为载体,以可视化现场图资料采集为源泉,以信息共享为基础,以指挥协同为目标,使灭火救援指挥工作的＂业务流＂与＂信息流＂高度融合,极大地提高了灭火救援指挥工作的效率、质量和水平,推进消防工作改革向纵深发展,使网上作战指挥引导实战成为现实。

火箭弹卷弧尾翼的轻量化研究

针对火箭弹卷弧尾翼在特定气动载荷下的轻量化问题,基于结构动力学理论,依托ABAQUS非线性有限元软件,建立了火箭弹卷弧尾翼的有限元模型。通过对比碳纤维复合材料(CFRP)和合金钢材料的卷弧尾翼的有限元分析,得出了碳纤维复合材料在满足强度和刚度的要求下,使卷弧尾翼减重达80%。该方法为火箭弹卷弧尾翼的轻量化设计提供了一种参考和借鉴。     

Elements of ‘armed non-state actors’ power: The case of al-Qaeda in Yemen

Over the past few years there is an apparent re-regionalization of al-Qaeda activity, intensified by the ongoing Middle East turmoil. Its main characteristic is a trend towards the abandonment of focoist strategies and their replacement by more popular-based ones. This article aims at evaluating their capacity to implement such a strategy shift and sustain the required level of violence. As a means of evaluating this capacity, this article proposes the use of a DIME (diplomatic, informational, military, and economic) framework, which will hopefully provide an alternative angle of theorizing and understanding ‘armed non-state actors’ (ANSAs). The model is applied in the case of al-Qaeda in the Arabian Peninsula (AQAP), which appears to have effectively developed the military and informational dimensions, due partly to its own prowess and partly to the Yemeni state's weaknesses and the shortcomings of counterinsurgency. In contrast, the economic and diplomatic dimensions suffer from the lack of resources and the anti-systemic nature of AQAP.
