The African Capacity for Immediate Response to Crisis: conceptual breakthrough or anti-imperialist phantom?

The creation of an African Capacity for Immediate Response to Crisis (ACIRC) is a sign of Africa's willingness to take its destiny into its own hands. Presented as a reaction to the slowness of the development of the African Standby Force (ASF), it is also a response to some of the ASF's conceptual weaknesses. This decision reflects a wish to establish an instrument better equipped to deal with the challenges Africa is facing. Departing from the (sub)regional logic of the ASF results from a desire to take into account the transnational nature of threats, while its enlarged mandate is meant to offer Africa the capacity to intervene in all kinds of conflicts, including by undertaking peace enforcement activities. But the obstacles on the road towards the actual creation and mobilisation of this capacity should not be underestimated. These include material difficulties, but also political tensions, between ‘small’ and ‘big’ states as well as between the African Union and subregional organisations. The risk then is high that the ACIRC, whose announcement came as a reaction to France's intervention in Mali, ends up joining the ranks of the many ‘anti-imperialist’ phantoms haunting the history of the Organization of African Unity/African Union (OAU/AU). Confronted by events considered ‘neocolonial’ initiatives, African actors have indeed traditionally reacted by launching grand projects that never got off the ground. However, by actually establishing this new instrument, they may also demonstrate that times have definitively changed.     

基于模型诊断的集合逻辑运算法计算最小碰集

在基于模型的故障诊断仿真系统的诊断流程中,由最小冲突集计算最小碰集是整个流程中的关键步骤。针对现有计算最小碰集方法中存在的缺陷,提出了运用集合逻辑运算法计算最小碰集,将冲突集表示为集合的逻辑"与"、逻辑"或"运算,通过其运算法则进行运算简化,可得到全部的最小碰集。该方法具有简单有效、数据结构简单、计算简便快捷和易于程序实现等优点。最后通过实例计算,验证了该算法的正确性、简单性和高效性。     

虚拟射击试验中的航迹融合方法

针对高炮武器系统虚拟射击试验中存在的航迹融合问题,研究了航迹在虚拟射击试验中的融合方法。分别通过虚实资源静态分析和动态分析,明确了试验中各试验要素内涵和虚实资源间信息交互的内容。由于虚实资源间交互的信息内容不同,易产生数据格式、信息理解等方面的不一致,且集中表现在数据处理上。因此,从空间一致性维护和时间一致性维护两个方面,给出了航迹在虚拟射击试验中的融合方法。     

论翻译中的文化依附

回归型支持向量机的机翼结冰冰型预测

飞机结冰严重威胁着飞行安全。针对机翼结冰冰型预测时不确定性因素较多、难以准确预测的问题,提出了一种基于回归型支持向量机的机翼结冰冰型预测方法。在建立冰型模型的基础上,利用回归型支持向量机(Support Vector Regression,SVR)获得冰型多项式系数,从而预测出相关飞行条件和大气条件下的冰型。仿真结果表明,该方法具有较好的预测能力,可以及时提供可靠的结冰信息,为保证结冰条件下的飞行安全提供了保障。     

基于作业成本原理的飞行训练保障费用模型

飞行训练保障费用是飞机使用保障费用中的重要组成部分,也是使用保障费用估算的重点和难点。结合目前航空兵部队实际工作情况,首先利用作业成本法的基本原理,对航空兵部队飞行保障阶段的作业进行划分,得出成本库及成本动因。其次针对军机飞行保障阶段的多种作业,建立基于作业成本法的飞行训练保障费用模型。最后通过算例说明其比其他估算方法所具备的优势。

台风浪过程对空中飞行器生存能力的影响分析

为了分析台风浪对飞行器生存能力的影响,以CCMP风场驱动WW3海浪模式,对发生在2008年9月的台风"黑格比"所致的台风浪进行数值模拟,并就台风浪对导弹等飞行器击水概率的影响进行计算分析。研究发现:以CCMP风场作为WW3模式的驱动场,对发生在中国海的台风浪进行数值模拟是可行的,模拟的海浪数据接近海浪浮标观测数据;击水概率大值区主要分布于台风的大浪区,当飞行器的飞行高度为12m时,击水概率基本在15%以上,近台风中心更是高达26%～30%,台风大浪区的外围的击水概率则基本都在10%以下;当导弹飞行高度为15m时,击水概率基本只有12m时的一半;无论飞行高度为12m还是15m,击水概率的大值区均集中分布于该台风行进方向的右半圆。击水概率的高值中心并不位于台风中心,这应该是由于台风中心存在一低风速的台风眼造成的。该研究为提高掠海飞行器的生存能力提供参考。     

Walking a tightrope: the International Criminal Court and conflict prevention in Africa

Many African countries gained political independence in the 1960s. This era of independence came with promises and great expectations of economic, political and social development. Fifty years later, it is certain that the promises and expectations of independence have not been easily realised. Perennial violent conflicts have continued to ravage many countries in Africa, causing the catastrophic breakdown of law and order. Therefore, one of the major issues in conflict resolution discourse in Africa is how to develop functional mechanisms for the prevention of violent conflicts. This article examines the capacity of the International Criminal Court (ICC) to act as a mechanism for conflict prevention in Africa. Notwithstanding the doubts and uncertainties associated with the impact of law on conflict transformation, this article argues in the main that the ICC contributes to conflict prevention in Africa by expressing global norms of international law, challenging the culture of impunity in some countries, contributing to general deterrence, speedily intervening in some violent conflicts, and contributing to building some records of atrocities by identifying who did what.
