基于SWOT分析的警卫情报工作优化研究

当前,警卫情报工作的范围已经扩展到警卫实战、预警、决策、管理等各个方面,但从总体上看,警卫情报工作仍需进一步优化,以满足日益增长的警卫实践需求。针对警卫情报工作的特点,采用SWOT分析法对警卫情报工作的内外部条件进行客观分析,提出针对性的优化策略,以提升警卫情报工作能力。     

适用于云计算的多接收方代理重加密方案

在云计算环境下,绝大多数信息处理和存储都被转移到云中心,用户终端的计算和存储能力将逐渐弱化。本文针对这一趋势,提出一种适用于云计算的多接收方代理重加密方案,充分利用云中心的分布式计算能力,使用随机数重用和密文聚合技术,大大降低了计算和传输负担,实验表明本方案具有较高的效率。     

基于流量均衡和跨层技术的星群路由算法

针对分布式星群网络业务通信QoS不高的问题,提出了一种基于流量均衡和跨层技术的分布式星群网络路由算法(TACA)。该算法首先通过跨层技术将物理层、MAC层的相关信息搜集起来,作为判断链路负载状况的依据;然后对不同类型的业务进行分类,根据链路负载状况和业务QoS级别选择不同的路由层次,从而均衡流量以提高QoS。仿真表明,该路由算法在一定程度上降低了星群的呼叫阻塞率和切换阻塞率,平衡了网络的负载,提高了网络吞吐量。     

The effect of deployment on first‐ and second‐term re‐enlistment in the US active duty force

Why should deployment affect re‐enlistment? In our model, members enter the military with naïve beliefs about deployment and use actual deployment experience to update their beliefs and revise their expected utility of re‐enlisting. Empirically, re‐enlistment is related to the type and number of deployments, consistent with the learning model. Non‐hostile deployment increases first‐term re‐enlistment but hostile deployment has little effect except for the Army, where the effect is positive. Both types increase second‐term re‐enlistment. Interestingly, first‐term members with dependants tend to respond to deployment like second‐term members. In addition, deployment acts directly to affect re‐enlistment, not indirectly through time to promotion.     

Aid versus sanctions for taming oppressors: theory and case study of the Iraqi Kurds

We model an oppressor aiming at victimizing an excluded group in his country, with two main variants. A foreign power affects his behaviour using either conditional aid, subject to the dictator’s participation constraint, or the threat of sanctions, broadly defined, subject to the credibility constraint. The choice between the two is either determined by the latter, or by their relative cost. Aid is preferred when the threat of sanctions is ineffective, and sanctions are too expensive. Sanctions might be imposed, if the threat is ineffective. A case study of the Iraqi Kurds after Iraq was subject to sanctions is presented.     

TERRORISM: FACTS FROM FIGURES 1

If international terrorism is on a rising trend, an important source of confirmation or refutation of this is time‐series data on terrorist activity. Using chiefly data collected by the RAND/MIPT consortium we show using basic statistical analysis that in the period 1968–2005 the yearly number of all international terrorist incidents shows no trend over time, but fluctuates year on year in a random manner. On the other hand some indicators do show a definite trend over time, principally the steady rise in the number of incidents that are death‐dealing in nature. A further conclusion is drawn, showing that the proportion of these incidents leading to deaths above a given level is virtually fixed.     

Strategic intelligence during coin detention operations – relational data and understanding latent terror networks

One aspect of the global “War on Terror” that has received limited coverage in the academic literature is the problem of detained persons as it relates to intelligence. This is a surprising oversight, given the number of detainees that the USA has been responsible for (over 25,000 were in custody in Iraq alone at one time during its peak). The detention environment offers a prime strategic intelligence opportunity for the US intelligence community to study the tactics and organizations of individuals who have been removed from the overall conflict. In this article an easily implemented collection program is recommended to be deployed in US/coalition detention centers. The primary recommendation is to gather relational data on detainee communication, both authorized and illicit, and to use these data to perform network analyses of terrorist groups and their individual members.     

飞行模拟系统中分布交互式视景的设计与实现

分布交互式视景是飞行模拟系统中的重要组成部分,是实现多机单通道（多通道）联网编队飞行的基础。提出了一种基于Mantis的分布交互式视景仿真系统,对视景系统的视景数据库、视景控制程序及网络结构进行了总体设计,构建了一个具有基本仿真功能,并且相对通用的分布式可视化实时视景仿真系统。并对多通道视景的同步、模拟器之间的时空一致性和三维模型简化等关键技术进行了研究与实现。该系统已经应用于实践,实现了直升机模拟器之间在同一环境下的联网飞行,并且取得了预期的视觉效果。     

LEACH—DRT算法中基于神经网络的数据预测算法

为了保证无线传感器网络中数据的完整性,针对基于LEACH路由协议的动态轮时间算法存在的问题,提出一种基于人工神经网络的数据预测算法。该动态轮时间算法中,部分簇因调整后的轮时间不足以完成数据的采集而丢失数据。数据预测算法结合传感器节点数据具有时空相关性的特点,将时空延迟算子引入神经网络模型,并通过建立的神经网络模型对数据进行预测。仿真时采用伯克利英特尔实验室的传感器数据,通过Mafl软件对模型进行测试并分析仿真结果。实验结果表明：该算法对连续多个数据的预测效果理想,预测误差始终保持在较低水平。
