面向指挥信息系统与训练仿真系统互联中间件研究

针对实装系统与仿真训练系统的运行机制、实现机理、技术规范和应用需求的差异,实装系统与仿真系统的互联问题制约着基于信息系统的指挥对抗训练,构建融“导”、“控”、“仿”、“裁”、“评”等功能为一体的综合训练环境是一种迫切需要。本文采用基于主动感知的数据转换方法、基于模板的信息智能交互方法和异构系统集成方法等构建中间件系统,并从数据转换桥接、时间管理桥接、导调监控桥接、指挥命令桥接和互联规范桥接等方面实现实装系统与仿真系统互联、互通。     

Dealing with the fast-changing environment in the eastern DRC

This paper is a study of the phenomenon of trans-border ethnic relations and its impact on national integration and citizenship in the countries of West and Central Africa where trans-border ethnic groups exist. Despite the existence of many such groups in these regions, and the numerous problems associated with the continued relations among these groups across their countries of abode, the phenomenon has not been seriously studied, especially as it concerns the identification of members of such groups and how they are viewed by members of other ethnic groups, as citizens of one country or the other. This paper notes that trans-border ethnic solidarity ordinarily presents the relevant African states with two possibilities, namely: enormous benefits accruing from regional integration and cooperation among states harbouring fractions of trans-border ethnic groups; or, debilitating conflicts within and between these states. It is the reality of the latter possibility that this paper examines. The states and the international system are often incapable of containing this phenomenon of trans-border ethnic solidarity and usually respond in hostile ways, ultimately manifesting in citizenship problems. The study shows, however, that what is needed is not conflict but cooperation – within and between states having fractions of a trans-border ethnic group, and within the international system, for the enhancement of national citizenship and development in West and Central Africa.     

Whatever happened to South America's splendid little wars?

South America has gained international media attention due to its ongoing arms race, with politicians and analysts warning about the possibility of war. Nevertheless, since the Chaco War in the 1930s, the region has seldom faced major inter-state wars, all of which have been short-lived and with relatively few casualties. This article will discuss in greater detail the ongoing arms race in South America, portraying it as a race ‘of levels’, with not all countries carrying out massive weaponry purchases. Finally, I will discuss regional geopolitics, geosecurity and integration as part of an analysis regarding the unlikelihood of war.

基于梯度方向二进制模式的空间金字塔模型方法

空间金字塔模型由于其优势在当前图像分类中得到了广泛应用。然而,其码本生成和特征量化这两个环节具有较高的计算复杂度。为了解决这个问题,提出了一种新的局部特征表述———梯度方向二进制模式,首先对图像稠密采样得到多个子图像块,再将每个子图像块均匀划分为2×2个网格,计算每个网格的梯度直方图,然后对所有网格的梯度主方向进行二进制编码并连接为二进制串值,该二进制串值转换的十进制数即为子图像块的特征表述,最后将该特征表述嵌入到SPM模型中。在标准分类数据库上的实验结果证明了本方法在算法耗时和分类精度上均优于基于SIFT的SPM方法。
