GAF协议是一种基于地理信息的无线传感器网络路由协议,由于采用多跳传输,将导致热区的产生。提出了一种优化邻居表算法,可以有效辨识GAF虚拟网格内的节点密度,从而选择密度大的网格通行,以均衡热区能耗,延长网络寿命。仿真结果验证了该算法的可行性。     

基于流体体积模型的双层油罐渗漏数值模拟

为了对钢制强化玻璃纤维制双层油罐贯通间隙空间进行优化设计,针对目前市场上主流双层油罐间隙空间的结构特点,应用计算流体力学数值模拟软件CFD,基于多相流流体体积模型,对双层油罐内罐发生渗漏后渗漏液体在贯通间隙空间的流动特点进行模拟计算。计算结果表明：液体在间隙空间流动时,其表面力对流动的影响占支配作用,体积力的作用可以忽略;当间隙垫片之间的距离≥0.8 mm,其对液体流动的阻碍作用开始减弱;主流双层油罐间隙空间的设计不合理,无法将油罐渗漏液体尽快引流到间隙底部。最后,根据液体在间隙空间的流动特点,对双层油罐间隙空间的设计提出了改进措施。

What is Doctrine?

‘Doctrine’ has been part of military vernacular for at least a century. Nonetheless, it is a concept which is rather under-explored. The aim of this article is thus to break doctrine down into its component parts in order to grasp what a military doctrine actually is. Thereafter, the article points out different ways to utilise doctrine as a military devise. A doctrine cannot be, or rather should not be, all things to all men. On the contrary, doctrine can be a tool of command, tool of education or a tool of change. The main upshot of the article is that the future of doctrine is far brighter than its critics want us to believe.     

Iron Cannot Fight 1 – The Role of Technology in Current Russian Military Theory

Contemporary Russian military theory is dominated by three schools of thought: the ‘traditionalists’, the ‘modernists’ and the ‘revolutionaries’. On the role of technology in future warfare, the traditionalists argue for both high tech and massive forces at the same time. The modernists are ready to trade manpower for technology, whereas the revolutionaries give technology full priority. Both the traditionalists and the modernists believe Russia, because of the country's technological lag and limited resources, should respond asymmetrically to the Western technology challenge. The revolutionaries, on the other hand, maintain that Russia must respond in kind. If not, the country will no longer be able to defend its sovereignty. The currently ongoing radical reform of the Russian military is a partial victory for the modernists, but which model or mix of models that will dominate in the future is first of all dependent on the Russian military's purchasing power and the state of the domestic defence industry.     

Reconsidering a Naval Blockade of China: A Response to Mirski

Sean Mirski's assessment of a naval blockade is an important contribution to the debate over how the United States should respond to China's growing military power. Nevertheless, it has three limitations. First, although distant and close-in blockades could be employed in tandem, analyzing them separately helps to explain when they might be used and how they could influence escalation. Second, while conventional countervalue and counterforce options could also be employed together, this would depend on the degree to which they overlapped and the order in which they were implemented. Third, a blockade could lead to unanticipated prewar, intra-war, and postwar challenges.     

How Probable is Cyber War? Bringing IR Theory Back In to the Cyber Conflict Debate

Many well-established explanations for war suggest that cyber weapons have a greater chance of being used offensively than other kinds of military technologies. This response article introduces a research agenda for the study of cyber war, and offers an example – principal-agent problems in cyber operations – to demonstrate how rigorous theoretical and empirical work may proceed.
