WDM光纤通信用窄带滤光片膜系补偿膜层的最优化设计

在WDM光纤通信系统中充当分波 合波器的全介质F B型多腔窄带滤光片的膜层层数较多,一般采用规整膜系结构,其各层膜的光学厚度均为监控波长的1 4整数倍.但仅采用规整膜层的膜系往往不能完全满足设计指标.因此,提出一种在基本满足设计指标的多层规整膜系上叠加少量非规整膜层的膜系设计方法,其中非规整膜层的光学厚度是在计算机上借助最优化方法寻优而得.

通信受限下分布式多传感器协同跟踪算法

在分布式多传感器目标跟踪系统中,由于局部融合中心(LFC)的物理限制(如:有限的频率信道、处理器容量有限等),只能接收有限个传感器的传送数据。此外,信息传输的方式也将影响传感网的使用寿命,因此,研究了通信受限下的分布式多传感器目标协同跟踪问题。首先对监视区内分布的传感器进行聚类分簇形成若干个子网,接着从通信能耗的角度出发,对传感器采集信息的传递路径进行最优路径规划;进而对子网局部状态进行估计,在子网信息融合中,分别采用最大距离和、最大化信息增量两种准则进行最佳传感器选择,最后通过各子网全局航迹融合实现分布式多传感器协同跟踪。仿真验证了算法的有效性。

‘Pounding Their Feet’: Israeli Military Culture as Reflected in Early IDF Combat History

Abstract

How did the Israel Defense Forces' (IDF) organisational and military culture shape their understanding of security threats, perceptions of warfare, and instinctive responses to security challenges? Israel's early military history is marked by the stubborn persistence of accepted patterns of thought and action. In the first twenty years of its existence, the IDF habitually came to sacrifice both political and military long-term and medium-term considerations in favour of the superficial, short-term satisfaction of its drive for action. The Israeli Army as an institution separated military actions from their political implications, and all too often, granted itself freedom of action at all levels of command. That myopic pattern led to recurring raids and minor operations during the 1950s, and contributed notably to the outbreak of the Six-Day War in 1967.     

Detecting Problems in Military Expenditure Data Using Digital Analysis

The UN asks governments to report key figures of their annual military budgets with the aim of creating trust among member states. This goal can only be achieved if the data reported is accurate. However, although there are many reasons for governments to falsify data, the UN does not check for manipulation. In this paper, we apply Benford’s law to the military expenditure data of 27 states taken from the UN register. Our analysis of the first digits shows that the states with the greatest deviations from the expected Benford distribution and therefore the lowest data quality are the USA and the UK.
