弹性支持的无限铁木辛柯梁对移动振动质量的响应

针对具有弹性基础的无限梁在移动的振动质量激励下的响应问题,采用考虑剪切变形和转动惯量的铁木辛柯梁理论建立梁的微分方程,并利用双重傅立叶变换求解,得到梁的运动方程。最后,通过一个数值计算的实例,分析了振动质量以及其移动的速度对梁的响应的影响。结果表明,振动质量本身对梁的响应的影响不可忽视。

Political systems,stability and civil wars

In this paper we analyze theoretically and empirically the stability of the different political systems; that is, their ability to prevent conflict. According to our model, the proportional system has a lower probability of group rebellion than the majoritarian system. In the empirical part we test the role of political systems in preventing civil wars. We show that democracy by itself does not play an important explanatory role, while the specific type of political system-majoritarian, presidential and proportional-does. The rationale of this result is that different political systems entail different opportunity costs of rebellion.     

Fleet management in European integration: the case of military helicopter support

The article focuses on both economics and spatial issues related to Maintenance Repair and Overhaul (MRO) of defence platforms in Europe. Using facts and figures related to costs, trends and fleet sizes evolution, the authors discuss the interest of a spatial reorganisation of MRO production. Given the fiscal situation of the main European countries with a modern army, the relevant scale to consider the reorganisation is certainly Europe. Through the example of defence helicopters fleets of a selection of European countries, the authors address the question of cooperation of the MRO. A greater cooperation in the support of fleets would lead to a spatial reorganisation of MRO. On one side economies can be expected from this reorganisation, but, on the other hand, new problems arise. Specifically, a number of costs associated with different forms of “distances” – geographical, operational and political distances – limit the potential savings that could be expected. This work provides insights on these important issues for the construction of a European defence, both in its political, military and industrial dimensions.

Performance and properties of Q‐Statistic monitoring schemes

In this article, we study the Shewhart chart of Q statistics proposed for the detection of process mean shifts in start‐up processes and short runs. Exact expressions for the run‐length distribution of this chart are derived and evaluated using an efficient computational procedure. The procedure can be considerably faster than using direct simulation. We extend our work to analyze the practice of requiring multiple signals from the chart before responding, a practice sometimes followed with Shewhart charts. The results show that waiting to receive multiple signals severely reduces the probability of quickly detecting shifts in certain cases, and therefore may be considered a risky practice. Operational guidelines for practitioners implementing the chart are discussed. © 2009 Wiley Periodicals, Inc. Naval Research Logistics, 2009
