一种面向应用的NOC缓冲区分配算法

片上互连网络是片上通信问题的有效解决方案,但其存在严重的资源限制.输入缓冲区占据片上网络总面积的显著部分,同时其容量大小对不同应用映射后获得的性能有重要影响.给出一种面向应用数据负载的NOC缓冲区分配算法,针对不同的应用映射,该算法可以根据数据流量分布特征实现各个路由器输入通道上缓冲区资源的定制分配.实验结果表明,使用该算法后,系统缓冲区资源得到了更有效的利用.与均匀分配缓冲区的NOC系统相比,采用该算法实现的缓冲区分配方案使系统在保持性能变化不大的情况下,能够节省约50%的缓冲区总容量.     

浅析储油罐安全容量的确定计算

由于油料具有热膨胀性，在运输和储存期间，如果油罐装油超过安全容量，当温度升高时，罐内油料体积膨胀，就可能导致溢油事故的发生，不仅造成油料数量的损失，甚至会引发火灾事故。正确确定不同油罐的安全容量，对油料的安全具有重要意义。文章阐述了油罐安全容量的概念，分析了安全容量计算不准确可能造成的危害，提出了油罐安全容量的计算方法。     

‘Responsibility to protect’ and the African Union: Assessing the AU’s capacity to respond to regional complex humanitarian and political emergencies

Despite its many institutional and political weaknesses and limitations, the African Union (AU) has been developing a variety of tools and mechanisms to respond effectively to complex disasters and emergencies (both natural and manmade) by building up a comprehensive regional security architecture. Furthermore, it has become the first and only regional or international organisation to enshrine the principle of ‘responsibility to protect’ (R2P) in its Constitutive Act. This regional approach to and formal endorsement of the R2P principle allowed it to assume a particular place in the promotion of peace and security in its area. This article aims to critically assess the effectiveness of the AU on the African continent by exploring its real capacity in preventing and responding to emergencies and violent conflicts, and therefore in rendering the principle of R2P operational. The article argues that the formalisation of principles does not necessarily mean their effective implementation. The organisation's use of the R2P principle is also greatly conditioned by internal and external factors.     

导弹结构热防护一体化设计与优化

针对导弹面临的严酷气动热力环境,基于传统波纹夹芯结构,为导弹设计了一种兼具承载和热防护功能的一体化结构。建立热-结构耦合计算模型,对一体化结构进行结构承载与热防护性能分析,结果表明:一体化结构在高温下具有较好的承载能力;增加一体化结构隔热层与内壁厚度有助于提高导弹的热防护效率。以一体化结构热防护效率最高和质量最小为目标,采用第二代非支配排序遗传算法实现了多目标优化,并认识到:一体化结构热防护效率与质量相互影响,设计时需要需综合考虑。     

新疆边境地区反恐情报保障问题研究

反恐情报保障是反恐行动的重要组成部分和决策依据。针对新疆边境地区情报力量建设较弱、情报保障手段单一、与有关部门缺乏有效的交流机制等问题，公安边防部门应采取加强情报力量建设、完善情报保障机制、充分利用各种情报手段和加强情报交流与合作等有效措施，不断提高反恐情报保障能力，掌握反恐怖斗争的主动权。     

论提高灭火救援组织指挥能力

建设科学合理、准确高效的灭火救援作战组织指挥体系,能提高消防部队的组织指挥的能力,以最快、最有效的方法处置各类事故,真正做到＂拉得出、冲得上、打得赢＂。阐述了建立灭火救援作战组织指挥体系的基本要求,提出了提高灭火救援指挥员指挥水平的对策。     

不确定环境下无人机区域目标搜索及载荷参数影响

针对不确定环境下无人机区域搜索问题,建立了实时探测更新的搜索方法,提出了机载光电载荷参数优化配置策略。建立了基于二维离散网格的无人机区域搜索模型,采用概率地图描述目标信息的实时获取与更新;引入不确定度指标、目标网格的重访和网格探测次数控制,建立搜索目标函数;建立了基于粒子群算法的搜索路径滚动优化方法;通过对任务区域平均探测时间步数和误判概率的估计分析,建立了机载光电载荷参数优化配置策略。使用蒙特卡洛方法验证了区域搜索方法的有效性和光电载荷参数配置对搜索效率、误判概率的影响。     

The FARC’s militaristic blueprint

This article intends to explain the outstanding sequence of success and failure exhibited by the FARC, the main Colombian guerrilla since the 1980s. It claims that such sequence is unintelligible unless the adoption by the FARC of a militaristic organizational blueprint at its 1982 7^th Conference is taken into account. By building itself like an army, the FARC could boost its combat capacity, maintain its structural integrity, and develop powerful mechanisms that held the whole structure together. At the same time, the militarization of the FARC also entailed significant risks and costs like political isolation and high personnel turnover. After describing the militaristic blueprint, the article compares the FARC with other irregular forces that operated in the Colombian context – a comparison which is important to understand the specificity of the FARC trajectory, as well as the benefits and costs involved in it. The analysis highlights the critical role of organizational dimensions in the explanation of civil war outcomes, and suggests that at least for some problems organizational dynamics should be observed at a low level of granularity.     

箭（弹）级间螺栓法兰连接结构准静载失效实验与数值仿真研究

基于火箭(导弹)级间螺栓法兰连接结构,简化设计并制作了一组原理性实验件,设计准静载加载实验测试系统,进行了两次准静载失效实验,并利用ABAQUS软件建立对应的有限元模型。实验中设计了螺栓力响应信号采集传感器,获得了螺栓力响应数据、加载力与加载位移等多组关键数据。根据实验效果和实测数据,分析了连接结构在准静载荷载作用下的失效机理,并对比验证了有限元模型数值模拟效果和精度与实验吻合较好。研究结论可为箭(弹)级间连接结构承载能力和失效实验设计提供参考。
