基于模糊支持向量机的发动机故障诊断方法

发动机的故障样本少,用神经网络进行故障类别的学习和分类往往会出现过学习、泛化能力不高以及局部极小点等问题。针对这一缺陷,将基于小样本理论的支持向量机学习方法应用到发动机的故障诊断中。同时讨论了3种多故障分类器的优缺点,并用引入模糊隶属函数的方法解决了“一对多”方法在构建多故障分类器时存在的分类盲区,提高了分类器的分类精度。用该方法对发动机常见的8种状态模式的样本进行训练和识别,训练样本和测试样本都有较好的识别率。

Discrete stochastic optimization using variants of the stochastic ruler method

We present two random search methods for solving discrete stochastic optimization problems. Both of these methods are variants of the stochastic ruler algorithm. They differ from our earlier modification of the stochastic ruler algorithm in that they use different approaches for estimating the optimal solution. Our new methods are guaranteed to converge almost surely to the set of global optimal solutions under mild conditions. We discuss under what conditions these new methods are expected to converge faster than the modified stochastic ruler algorithm. We also discuss how these methods can be used for solving discrete optimization problems when the values of the objective function are estimated using either transient or steady‐state simulation. Finally, we present numerical results that compare the performance of our new methods with that of the modified stochastic ruler algorithm when applied to solve buffer allocation problems. © 2005 Wiley Periodicals, Inc.

Lost in transition: the South African military and counterinsurgency

Washington's growing reliance upon international private security companies (PSCs) will lead to these firms becoming prominent vehicles in the prosecution of the counterinsurgency in Iraq. This shift, however, risks labeling PSCs as mercenaries and presents considerable challenges regarding the control of non-state violence. Moreover, tradeoffs exist regarding the different nationalities of PSC personnel. Utilization of personnel from the developed world risks compromising the capabilities of Special Operations Forces. Additionally, shifts in casualty recognition amongst US policymakers and the media suggest that the private option is becoming politically salient and thus less useful. Many developing world states are increasingly concerned about how the global outsourcing of security sector expertise risks their stability and ability to execute coherent policy. Finally, the employment of Iraqis in PSCs sends mixed messages to the Iraqi populace about the need for and the effectiveness of a cohesive and responsible indigenous security sector.

Frankly, I'd like to see the government get out of war altogether and leave the whole feud to private industry.

TERRORISM AND DETERRENCE POLICY WITH TRANSNATIONAL SUPPORT 1

This study provides an explanation of terrorism by examining interactions between the terrorist group with a minority as a potential pool of recruits and the government supported by a majority. A hawkish deterrence policy makes it more risky for terrorists to launch attacks, but heightens the anti‐government feeling of the terrorist group. In addition, the payoff for the government depends not only on the payoff loss associated with the level of terrorism, but also on the political payoff from the action itself of adopting a hawk policy due to its politicians’ vested interests. We first show that whether the deterrence policy should be ‘hawk to ‘dove is closely dependent on the relationships among the risk associated with terrorism, the anti‐government feeling of the terrorist group, and the political payoff for the government. This study then introduces transnational support enhancing the capability of a terrorist group to intensify its activity and shows that the emergence of transnational support may cause the government to reform its deterrence policy from ‘dove’ toward ‘hawk,’ with terrorism intensified in the society.
