TERRORIST THREATS AND TRANSITIONAL DYNAMICS IN AN OVERLAPPING GENERATIONS MODEL

Previous research has shown that the duration of a civil war is in part a function of how it ends: in government victory, rebel victory, or negotiated settlement. We present a model of how protagonists in a civil war choose to stop fighting. Hypotheses derived from this theory relate the duration of a civil war to its outcome as well as characteristics of the civil war and the civil war nation. Findings from a competing risk model reveal that the effects of predictors on duration vary according to whether the conflict ended in government victory, rebel victory, or negotiated settlement.     

ALTERNATIVE NARRATIVES FOR ARMS CONTROL

The efforts of President Barack Obama and his administration to restore the United States as a driving force of multilateral arms control and nonproliferation negotiations are commendable, yet the lack of progress on such issues over the last eight years has ensured that U.S. policy has not kept pace with changes in the geostrategic environment and the evolving security agenda. Meanwhile, an alternative agenda has been articulated by non-Western countries. This article focuses on the arms control perspectives of Non-Aligned Movement states and others that have begun to embrace the idea of “disarmament as humanitarian action.” It explores this idea in the context of recent initiatives and argues that if the Obama administration wants to make progress on its arms control and nonproliferation priorities, it should consider a multifaceted approach that incorporates this emerging alternative agenda.     

INTEGRATING NUCLEAR WEAPONS STOCKPILE MANAGEMENT AND NUCLEAR ARMS CONTROL OBJECTIVES TO ENABLE SIGNIFICANT STOCKPILE REDUCTIONS

In his 2009 Prague speech and the 2010 Nuclear Posture Review, President Barack Obama committed the United States to take concrete steps toward nuclear disarmament while maintaining a safe, secure, and effective nuclear deterrent. There is an inherent tension between these two goals that is best addressed through improved integration of nuclear weapons objectives with nuclear arms control objectives. This article reviews historical examples of the interaction between the two sets of objectives, develops a framework for analyzing opportunities for future integration, and suggests specific ideas that could benefit the nuclear weapons enterprise as it undergoes transformation and that could make the future enterprise compatible with a variety of arms control futures.     

影响柴油机喷雾数值模拟精度的若干因素分析

为探明影响柴油机喷雾数值模拟精度的若干因素,采用通用商业软件FLUENT对柴油机喷雾特性进行了CFD模拟计算,分别研究了网格尺寸、喷雾粒子数和最大时间步长对油束几何形状及油束贯穿距的影响.结果表明,网格划分的精度和喷雾粒子数量的多少对计算结果的正确性和油束的几何形状有直接的影响,网格尺寸过大或喷雾粒子数过少则喷雾几何形状失真.最大时间步长对数值模拟的精度在一定的范围内影响是比较小的.     

高精度气压源的Fuzzy-PID控制研究

设计了Fuzzy-PID双模控制器并应用到高精度气源压力控制系统中.试验表明,单纯采用PID控制的高精度气源压力控制系统具有精度高的优点,但不适应系统参数的变化.Fuzzy-PID双模控制器具有响应速度快、稳态误差小、鲁棒性强的优点.通过试验比较了传统PID、Fuzzy控制和Fuzzy-PID双模控制3种控制策略,试验结果表明,Fuzzy-PID双模控制器综合了Fuzzy控制和PID控制的优点,适用于高精度气源压力控制系统.
