北斗系统新民用导航电文历书参数算法与性能分析

研究新公布的北斗民用导航电文中的两类历书与北斗二号导航电文历书的差异,对比分析各类历书对接收机首次定位时间的影响。利用实际的历书数据,比较不同历书类型的用户算法,分析不同龄期数据对接收机首次定位性能的影响。结果表明,高精度历书在1周的数据龄期内性能较为稳定,中等精度历书精度稍逊于高精度历书,但由于简化了电文空间,能接近高精度历书性能。简约历书进一步简化了参数数目和电文空间,尽管位置误差达到了数百千米,但却能在数月之后保持相应精度,有利于缩短接收机首次定位时间。     

Honour,Comradeship and Betrayal: Lord Capel’s Sword

The sword which is the subject of this article and which will be referred to as the Capel sword, is a fine example of what has become known as an Irish basket-hilt. Whilst there are other examples in existence, what makes this sword unique and particularly important is the fact that it is known to have been owned by two important Royalist military leaders, Lord Arthur Capel and Sir John Owen. These two extraordinary men came from different backgrounds but their fate was linked through circumstances beyond their control. The story this sword tells is one of comradeship, loyalty, total belief in a cause, betrayal and ultimate sacrifice.

The Saudi air war in Yemen: A case for coercive success through battlefield denial

The present-day conflict in Yemen is a valuable case study in the coercive use of airpower. The Saudi-led bombing campaign demonstrates the challenges inherent in applying a punishment-based strategy in a civil war, where coercive mechanisms operate differently than in interstate conflict. The audit from Yemen vindicates the effectiveness of a denial-based strategy and offers insights on the relative utility of interdiction and close air support in advancing that strategy. This examination dissects the campaign, assesses its effectiveness, and extracts insights useful both to the analysis of similar conflicts and to the evaluation of U.S. foreign policy alternatives.     

Competitive Statehood in Libya: Governing Differently a Specific Setting or Deconstructing its Weak Sovereign State with a Fateful Drift Toward Chaos?

Abstract

Libya in 2011 witnessed a real process of political change, though different from all the policy-oriented jargon equating transition with a teleological transition to democracy. Due to the resilience of the Qadhafi regime in power and with the essential role of NATO intervention, the process was eased out by a eight-month civil war. Governance in post-Qadhafi Libya was not done through the rebuilding of centralized authorities. But it took the specific form of the emergence of multiple non-state actors embedded in local dynamics and then connected with weakened central authorities that had access to the huge Libyan resources. That raised complex questions about the quality of this mode of governance, especially at a time of pressing problems for Libya and its neighbors, whether direct ones (Tunisia, Egypt, Mali) or farther countries across the Mediterranean sea: terrorism with the expansion of Da’esh into the country and flows of refugees crossing Libya’s uncontrolled borders and flowing into Italy and then Europe by thousands.     

Developing Civil Society in the Non-state Sphere: Welfare and Rights-based Organisations Associated with Ethnic Armed Groups in Myanmar

Armed groups are usually seen as threats to humanitarian action but less attention has been paid where they provide assistance to constituent populations. Ethnic armed groups (EAGs) in Myanmar have developed associated welfare organisations that perform this role. This article argues this is due to EAG social embeddedness and flexibility to changes in sources of funding and support, and the influence of their relations with international humanitarian organisations. This article further contends a subset of advocacy, health and education organisations have evolved to form a nascent civil society within the political and social non-state sphere of some established EAGs.
