动基座条件下垂直发射装置状态参数检测方法

针对在海上动基座条件下舰载垂直发射装置的安装精度和发射架导轨状态参数的检测问题,在分析其技术难点的基础上,提出了利用测距仪差分原理实现对水平误差的检测;采用数字激光自准直仪解决发射筒各架体的垂直度测量。并通过对该检测方法进行的不确定度分析与计算,验证了该检测理论的正确性。     

润滑油基础油黏度调和模型的优化选择

通过测定46#机械油基础油与PAO8（8#聚α-烯烃油）不同比例混合后油品的黏温性能,研究了黏度偏差率随测量温度的变化规律．通过实验发现：国际通用黏度调和计算模型能较好预测混合基础油的高温运动黏度,黏度偏差率最大值为3．56％;而美国标准局的黏度调和计算模型在混合基础油的低温运动黏度计算上精确度更高．     

A drive to regime change through nonviolent economic warfare: The post-Mugabe era, 2017–2019

ABSTRACT

This article examines efforts made by the Movement for Democratic Change Alliance to bring about regime change through nonviolent economic warfare including its subsequent failure. The 30 July 2018 harmonised elections in Zimbabwe led to a victory by Emmerson Mnangagwa but it was disputed by Nelson Chamisa. Since August 2018, the political opposition led by Chamisa sought to make the country ungovernable by waging a nonviolent economic war nicknamed Kuzvidira jecha (pouring sand) against the Mnangagwa administration. This was punctuated by price hikes, fluctuation of the local currency, artificial food stuff price hikes and fuel shortages which caused serious challenges for most Zimbabweans. This was primarily intended to bring about regime change via public unrest against the Mnangagwa regime. On the contrary, the anticipated public uproar failed to foster regime change in Zimbabwe despite widespread adverse socio-economic effects. This led to the nonviolent participants resorting to violent tactics instead of adhering to nonviolence. Consequently, it was the failure to adhere to nonviolent principles by opposition advocates which forced the Mnangagwa regime to deploy its own instruments of violence in an effort to protect lives and property.     

Currency Warfare and Just War: The Ethics of Targeting Currencies in War

ABSTRACT

Is Currency Warfare defined as, the use of monetary or military force directed against an enemy’s monetary power as part of a military campaign, a just way to fight a war? This article explores the ethics of waging currency warfare against the Just War Tradition’s principles of jus in bello (just conduct in war) and its criteria of discrimination and proportionality. The central argument is that currency warfare is inherently indiscriminate but may be proportionate when policy makers consider the nature of the threat confronted and the targeted currency's level of internationalization, that is, to what degree it is used in foreign transactions or used as a foreign currency reserve. I evaluate this argument against historical cases during the Second World War (1939–1945), the Gulf War (1990–1991), subsequent operations against Saddam Hussein in the early 1990s, and the ongoing campaign against ISIS.
