Damage assessment of the target area of the island/reef under the attack of missile warhead

Under the background of vigorously developing facilities of island/reef in the world, the economic value and strategic significance of the island/reef have become increasingly important. Unfortunately, they may easily become the attacking target of missiles in the war time. Therefore, aiming at the damage quantification of the targets in the island/reef under the missile attacking, a macroscopic damage assessment model for the target area is proposed in this paper. The model focuses on the construction of the assessment model framework. Firstly, the analytic hierarchy process and the grey relational analysis are applied to measure the importance of each target in the region through four indicators of the target hazard, striking urgency, damage advantage and mission relevance, respectively. Secondly, based on the damage mechanism of shock wave and fragments to target, the corresponding damage model is established, and the damage grade of each target in the evaluated area is obtained according to the damage criteria and grading standard. Finally, the model obtains the overall damage grade of the target area by employing the fuzzy comprehensive evaluation method, with synthesizing the importance and the damage grade of each target. Through the verification of an example, it demonstrates the certain feasibility of the model and provides a certain basis and reference for the subsequent research.

Coordination as showcasing: the establishment of Norway’s Afghanistan Forum

In complex operations such as the interventions in Iraq and Afghanistan, where multiple government ministries are involved in putting together a state’s contributions, the use of national-level coordination bodies has become more widespread. Research has taken for granted that the rationale behind these bodies reflects their declared aim – enhanced coordination as a means to improve mission effectiveness. However, they appear to have had modest effect on coordination. That notwithstanding, they seem to remain popular. This prompts us to ask why such bodies are actually established. This article – based on in-depth interviews and archival records – critically explores the establishment of Norway’s ad hoc, inter-ministerial, political-level Afghanistan Forum. Distinguishing between a structural-instrumental, a cultural-institutional and an environmental perspective from organizational theory to structure the analysis, this article shows that the declared purpose of the forum, inter-ministerial coordination, proved less important than showcasing coordination efforts and keeping the coalition together. In addition, national traditions in handling coordination challenges in the central government apparatus and powerful international reforms helped bring the forum about. This has implications for research on the rationale and effectiveness of these bodies, and also for understanding their policy relevance.

运动目标轨迹分类与识别

运动目标轨迹识别是运动分析中的基本问题,其目的是解释所监视场景中发生的事件,对所监视场景中运动目标轨迹的行为模式进行分析与识别,智能地做出自动分类.对轨迹有效性判断后采用K均值聚类,引入改进的隐马尔可夫模型算法,针对轨迹的复杂程度对各个轨迹模式类建立相应的隐马尔可夫模型,利用训练样本训练模型得到可靠的模型参数,计算测试样本对于各个模型的最大似然概率,选取最大概率值对应的轨迹模式类作为轨迹识别的结果,对两种场景中聚类后的轨迹进行训练与识别,平均识别率较高,实验结果表明该方法是有效的.
