基于灰度共生三角阵的炮膛图像分析

为解决炮膛疵病图像粗分类时缺少聚类和分类特征的问题,引入了灰度共生三角阵（Grey Level Co-occurrence Triangular Matrix,GLCTM）的方法。通过对炮膛样本图像GLCTM特征参量的计算与分析,确定了GLCTM的参数;根据特征参量的相关性分析结果,选择了其中7个作为炮膛图像的特征参量。样本图像的实验结果表明,炮膛图像的GLCTM特征参量取值与图像灰度的直观特点之间存在对应关系。

Defining quantitative criteria for the physical protection system effectiveness of nuclear facilities

The article is devoted to problems of defining quantitative criteria for the physical protection system (PPS) effectiveness of nuclear facilities. The article briefly describes the scheme of the PPS development used in the nuclear industry in Russia, gives a review of existing approaches to defining the minimal acceptable value of the system's effectiveness, and reveals advantages and disadvantages of the approaches. The article describes in detail an approach based on facility categorization by potential losses and a technique of defining the minimal acceptable value of the PPS effectiveness developed on its base.     

North European security after the Ukraine conflict†

Russia’s illegal occupation and annexation of the Crimean peninsula in February–March 2014, and the country’s well-documented involvement in the separatist conflict in Eastern Ukraine, have led to a significant worsening of Russia’s relations with the West. Vladimir Putin’s move to redraw Russia’s southern borders through the use of military force and subversive measures has given rise to an uncertainty that goes well beyond the post-Soviet space. Since 2014, North Atlantic Treaty Organization (NATO) has had to reassess many aspects of its relationship with Russia. The alliance has also initiated various measures to strengthen the military security of its eastern member states, particularly the Baltic states, Poland, and Romania. Further to the North, NATO’s northernmost member – Norway – is following developments in Russia with a heightened sense of awareness. The same goes for non-aligned Sweden and Finland, which are trying to adapt to the emerging, and increasingly complex, security environment in Northern Europe.     

Swedish–Finnish naval cooperation in the Baltic Sea: motives,prospects and challenges

Recently, Finland and Sweden decided to substantially deepen their defence cooperation and this project involves creating a bilateral standing Naval Task Group (SFNTG). The present article aims at examining the deepening naval cooperation between Finland and Sweden from a regional integration perspective, focusing on its motives, current challenges and future prospects. Driven by perceptions of common challenges and desires for cost-effectiveness, and strengthened by recent successes on sea surveillance and a combined Amphibious Task Unit, the bilateral project has considerable potential to achieve success. To fulfil its objectives, substantial legal changes in both countries are required to allow the use of force on each other’s territorial waters. To cater for the requirement of not conflicting with EU, NORDEFCO or NATO cooperations, the bilateral Task Group must operate according to NATO standards and by using English as the language in command and control. The costs of adjusting the naval units to NATO’s technical requirements are far from negligible and this issue still remains to be solved. If Finland and Sweden manage to incorporate new policies, common structures and common organisational norms among their navies, an even deeper integration, as in Belgium and the Netherlands, are conceivable.     

军事通信网节点重要度评估方法

针对军事通信网的应用环境和业务流传输的特殊性,考虑节点类型以及节点之间的相互关系,将节点按功能分为侦察节点、处理节点、指控节点、行动节点、传输节点五类节点。根据军事通信网信息流传输的特点,改进了传统的网络介数基本概念,定义了符合军事通信网特征的节点和链路重要度的新指标。最后,通过实例对军事通信网的节点重要度进行仿真计算,画出了所有节点重要度柱状分布图。     

基于傅立叶图像重建的车用换热器表面缺陷检测?

针对车用换热器表面缺陷检测问题,提出一种利用傅立叶图像重建提取方向纹理表面缺陷的算法。该算法采用局部二值模式（ LBP ）描述去除光照影响并对LBP图像进行快速傅立叶变换,通过频率域滤波和图像重建有效去除方向纹理的影响,由二值化及团块分析最终提取换热器表面缺陷区域。实验结果证明,本文算法可以快速、有效地检测出换热器表面缺陷。
