一类有增益网络的最大流模型

一般带容量限制的网络图中流出源点与流入汇点的流量相等,但在实际应用中,存在一类流量经过弧发生变化的网络,使得流出源点与流入汇点的流量不相等。针对此类问题,建立了增益网络最大流模型,并通过增设虚弧将增益网络转换成循环网络,利用循环网络中汇点流量瞬间平衡的优点简化了模型。最后,结合实例进行分析,编写程序对实例进行了计算,计算结果验证了该模型的有效性。     

进气口位置和进气体积流量对油罐油气惰化置换效率的影响

采用机械通风方式对油罐油气进行处理,具有安全性差、通风时间长和效率低下的缺点;利用燃惰气对油罐油气进行处理,可较好地克服上述缺点。在前期研究的基础上,设计模拟实验台架,以燃惰气为介质,实验研究进气口位置和进气体积流量对燃惰气惰化置换油罐油气的影响。     

大深度复合同振式矢量水听器设计

针对目前深海无人移动平台缺乏与其工作深度相匹配的复合同振式矢量水听器的问题,采用薄壁铝合金球壳作为矢量通道,压电陶瓷圆环作为声压通道,设计制作了一型大深度复合同振式矢量水听器,并用理论计算、有限元仿真和实验测试的方法对其声学性能和耐压性能进行了验证。该水听器的外径为85 mm,质量为398 g,平均密度为1 240 kg/m~3,工作频段为20～3 000 Hz,矢量通道呈余弦指向性,灵敏度为-187 dB@500 Hz,声压通道无指向性,灵敏度为-191 dB@500 Hz,耐压深度为2 000 m。海上试验表明,该水听器能够搭载在水下滑翔机等深海无人平台上执行声学探测任务,在大深度声学探测领域具有重大的应用价值。     

浅议行政执法责任制

行政执法责任制是依法行政的重要保障。当前实施行政执法责任制存在着一些问题,应从行政执法责任制的本质和操作规程、依法界定执法职责、建立评议考核机制等三个方面进行改革。     

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.
