利用整帧翻转的SRAM型FPGA故障注入加速算法

不可恢复异常比特位(unrecoverable-sensitive bits, UR-SB)不能通过定时刷新修复,会造成卫星载荷在轨服务的长时间中断,是地面故障注入试验需要着重评估和改善的。但UR-SB占比极低,若采用传统逐位翻转故障注入方法,其测试耗时太长,效率极低。提出了一种基于整帧翻转的静态随机存取存储器型现场可编程门阵列的故障注入加速算法,其通过整帧翻转能够快速筛除不存在UR-SB的配置帧,并进一步用二分法对存在UR-SB的配置帧进行快速搜索,有效加速了UR-SB的精确定位过程。以在轨常用XQR2V3000器件为例,理论分析在较差情况下测试效率可提升207倍,信号生成载荷实测结果最高可提升949倍,理论分析和实测结果均验证了所提加速算法的有效性。     

利用分时刷新和位置约束的卫星载荷BRAM抗辐照设计方法

为解决星载资源严格受限条件下,静态随机存取存储器型现场可编程门阵列中块随机存储器(block random access memory, BRAM)的轻量级、高可靠抗辐照加固难题,提出了一种基于分时刷新和位置约束的卫星载荷BRAM抗辐照加固设计方法,通过监控算法执行时隙实现BRAM分时刷新,并增加位置约束有效降低三模冗余后两模设计同时发生异常的概率,以较少的资源消耗有效提升BRAM在轨抗辐照可靠性。重离子加速试验结果表明,采用分时刷新和位置约束加固方法后,卫星载荷单粒子功能中断截面下降约81.63%,在轨BRAM异常由3颗星2年发生3次减少为25颗星2年未发生,在轨抗辐照可靠性大幅提升。

Youth Between State and Rebel (Dis)Orders: Contesting Legitimacy from Below in Sub-Sahara Africa

Abstract

The Sahel has gained attention in international politics as one of the central theatres in the war on terrorism. International actors in this war seek alliances with states in the region, reinforcing the latter’s military strength and their legitimacy from outside. At the same time, increasingly-connected young populations question the legitimacy of their states, and contest that legitimacy from within and below. In the absence of states delivering any reasonable form of social contract, young people become torn between different governing orders and find themselves in a liminal space. In this article we present the cases of youth in Mali and Chad, who find themselves in a period of re-definition of their position in society and hence search for legitimate structures representation. In this search they may frame their belonging in terms of ethnicity, religion or political opposition – and increasingly also in adherence to global citizenship. New information flows and connectivity among young people in these regions, and between them and the diaspora, has given a new turn to their search for citizenship/belonging and rightful representation. However, whether their search will be successful in this geopolitical context is questionable.

EU armed forces and social media: convergence or divergence?

This article explores how armed forces in EU member states work with and view social media in national and international settings, and what the patterns of convergence/divergence are on these issues. To that end, a questionnaire targeted at EU armed forces was constructed. An index of qualitative variation was calculated to explore the relative convergence among respondents (n = 25) on issues of risks and opportunities with using social media nationally and internationally. Consistent with previous research on European armed forces, we found higher levels of divergence than convergence. Contrary to our expectations that similar challenges, joint international standards, and membership in international organizations would foster convergence with regard to social media use in areas of deployment, we found that convergence appeared foremost pertaining to the domestic level. Policy divergence was strongest in areas of deployment.
