Reopen a joint school of military government and administration?

Today there are many calls for other elements of the government to do more to ‘do their part’, assist the military to restore order and stability and ‘win the peace’ in Iraq and Afghanistan, and prepare for similar roles in future conflicts. The authors here instead briefly review the history of US armed forces’ involvement in military governance operations from the Mexican War through World War II, and recommend the re-establishment of a School of Military Government similar to that created during the latter conflict.     

载体干扰磁场补偿方法

获得载体航行路径上各点地磁场的精确测量值是地磁匹配导航的前提,而载体上各种干扰磁场的存在会引起磁力仪输出的偏差,影响匹配的精度,因此必须对载体干扰磁场进行补偿。在分析载体干扰磁场特性的基础上,提出利用矢量测量值对地磁场总场值进行补偿的方法。该方法首先根据矢量磁力仪的测量模型得到关于载体磁场参数的非线性方程,然后采用非线性参数估计方法估计出精确的载体干扰磁场系数,最后再利用估计结果对测量值进行补偿。通过仿真对该方法的有效性进行研究,并设计了半实物实验对其实用性进行验证。结果表明采用本文提出的方法补偿后地磁场总场值的测量误差在20nT以内,而且该方法参数估计精度高,应用方便,可以有效地对导航载体干扰磁场进行补偿。     

PHEV电池电荷状态估计设计及仿真

电池管理系统(battery management system,BMS)是混合动力汽车(parallel hybrid electric vehicle,PHEV)能量管理系统中的核心组成部分,而其中电池电荷状态(state of charge,soc)则是PHEV控制策略中的重要参数.针对PHEV动力电池组SOC系统高度非线性和复杂性的特点,提出了一种基于改进的BP神经网络的HEV动力电池组的实时SOC估计,并对网络的收敛性进行了证明.利用大量PHEV动力电池组在行驶过程中充放电的数据样本,对神经网络进行网络训练并且进行仿真.结果表明,与传统离线SOC估计方法相比,能够有效地减小误差,提高电池SOC的精度.

武警院校军事学研究生教学管理与保障存在问题及对策

武警院校军事学研究生教学管理与保障存在着课程体系不够科学、教学运行管理不严密、教学保障不到位及教学质量评价体系不完善等问题。应采取有效措施修订现行课程体系,建立和完善研究生教学质量评价体系,改善教学条件,形成教学管理合力育才的良好机制。     

基于概念知识树的军事想定描述方法

为了增强军事想定描述规范的知识性,在研究概念知识树的基础上提出了一种基于概念知识树的军事想定描述方法.首先,以军事想定描述需求为依据,使用概念知识树对军事想定的元素进行描述和组织,建立军事想定的知识表达模型;然后利用军事想定定义语言(military scenario definition language,MSDL)框架和5Ws对军事想定进行系统性组织,形成符合军情的想定描述规范.在多兵种联合仿真实验中应用了该描述方法,实现了想定在不同兵种之间的共享,证明了该描述方法的可用性和有效性.     

The financing factor in military trade

Available sources value transfers of weapons irrespective of whether they are paid for and how. Data from the U.S. indicates that the shares of arms given for free or on credit are high. If other arms exporters, all military aid and all credits used for military purposes are considered, which is done here on the basis of rough estimates and an opportunity cost model, the true cash costs of weapons in the year of the actual transfer are small. On the other hand, the financial burden of earlier arms imports via debt service has grown over time. It most probably exceeded the true cash cost of imports of arms in the late 1980s. Large differences between arms transfer data and the actual true costs of arms transfers means that analysis of the economic effects of arms imports without considering these financial aspects makes little sense.     

Country survey VIII: Federal republic of Yugoslavia

This survey article focuses on defence economics issues and provides data and analysis on the Federal Republic of Yugoslavia's (FRY) defence policy, defence spending, the size of its armed forces, its defence industries and the cost of the civil war. The main section is devoted to the period from 1990 to the present and deals with the following aspects: the situation after the break‐up of the former Yugoslavia, general economic data; the cost of the civil war, the defence budget; the armed forces; the manufacture of armaments and the structure of the defence industry.     

Reward,punishment or inducement? US economic and military aid, 1946–1996

If the US has wielded power as global hegemon, then there should be evidence of a linkage between American resources and the ability to influence behavior. However, there is widespread disagreement on how this power is manifested (see Krause, ). Methodological and epistemological issues have hampered empirical studies of US hegemonic behavior. For example, does the US reward past behavior or does it offer inducements for future behavior? We document and discuss these issues in terms of the aid–foreign policy compliance nexus. The empirical portion of our paper tests whether US military and non‐military aid are correlated with foreign policy similarity. The main merits of our study are that: (1) we test a new measure of foreign policy similarity developed by Signorino and Ritter () and compiled by Gartzke et al. (); (2) we relax the causality issue and test using vector autoregression (VAR) for 76 developing countries; and (3) our time horizon is a minimum of 30 years for each country. Our central finding is that aid is most often used as a reward. More specifically, foreign policy similarity leads to greater economic aid for most African countries, foreign policy similarity leads to greater military aid for a majority of Latin American states, and there are no overarching patterns for Asia and the Middle East. We discuss the implications of our findings in the context of the bargaining and structural approaches to statecraft.
