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. 相似文献

This article presents survey data on the African Peace and Security Architecture (APSA). It focuses explicitly on two aspects: the internal constitution and achievements of the APSA; and coordination and cooperation with external actors, such as Regional Economic Communities, the United Nations and the European Union. The survey, conducted between October 2011 and December 2012, targeted 198 security experts in international organisations, think tanks, academia and non-governmental organisations. It reveals the APSA's current stage of development, achievements and challenges. 相似文献

为了满足海军训练的需求,提高训练的可信度,需要研制逼真度更高的模拟训练设备。为此,利用基于组件的开发方法设计了混合配置的反潜武器作战系统训练模拟系统。该系统不仅包括仿真设备,还包括实装设备。系统将两个独立的结构整合成一个系统,因此需要软件构架的独特设计。讨论了这一混合配置的系统训练模拟器的设计,提出了在实装战术网络和仿真网络之间的独特的系统接口设计,成功支持了训练模拟器的开发。基于组件开发方法的设计和思路对于训练模拟器材的设计具有很好的参考价值。 相似文献

科学计算产生和分析的数据规模日益增长,高性能计算机的存储系统在体系架构和软件管理方法上面临重大挑战。针对天河-2系统的新型分层混合存储架构,提出一种由应用程序耦合的协同式突发缓冲技术来有效利用其存储资源优势。该方法采用运行时动态耦合的方法,将临近计算任务的分布式高速存储资源聚合成为一个的巨大的协同式突发缓冲区,通过采用文件命名空间投影的映射方法组织全局数据视图,利用位置亲和和感知数据意图的方法来挖掘空间局部性和时间局部性,并利用应用并发度感知的策略优化数据移动效率。天河-2系统的测试结果表明,该方法能够有效优化多种典型应用场景,可获得高可扩展的突发并行输出带宽和稳定的持续并行输出带宽,可显著提升数据分析场景的输入/输出性能,适合应用于大规模超级计算机的存储系统。 相似文献

陆军作战仿真模型标准化研究 总被引:1,自引:0,他引:1
模型标准化是规范仿真模型开发,避免低水平重复建设的重要环节。在对陆军作战仿真模型体系进行分析和归纳的基础上,对仿真模型架构、模型构建、模型管理以及模型交互进行了标准化设计,提出了基于插件机制的“柔性”仿真模型架构、仿真实体组件化建模机制、采用“方案-单元-实体-组件”方式的仿真实体管理机制以及采用消息驱动、事件订购和分发方式的模型交互机制。 相似文献
