基于标注事件图的空间数据库主动规则终止性分析

主动规则的终止性分析强化了规则的设计高效性。给出主动规则元模型的概念作为主动规则终止性分析和比较的基础;对精化触发图进行扩展,提出标注事件图分析模型。结合实例给出终止性分析算法。与各种方法的对比说明标注事件图是可应用于终止性分析的通用抽象模型。     

基于免疫FNN算法的加热炉炉温优化控制

针对复杂钢坯加热过程,提出了一种免疫克隆进化模糊神经网络(ICE-FNN)控制算法。首先根据现场样本数据建立过程神经网络模型;然后基于该模型,采用模糊神经网络控制器(FNNC)规则优化算法,确定FNNC的最佳规则数;最后由FNNC的规则优化所得参数构造初始种群的一个解,采用免疫克隆进化(ICE)算法对FNNC参数优化。该算法具有全局寻优和局部求精能力,仿真结果证实了其有效性。     

Historical and Political Background to the Erosion of the Rule of Law and Human Rights During Sri Lanka’s Civil War and the Way Forward

The Sri Lankan Civil War (1983–2009) is regarded as a violent reflection of deepening divides along political and ethnic lines. During this civil war the Sri Lankan Government and its security forces have been implicated in unlawful killings carried out in a pervasive manner against civilians, whilst at the same time specifically targeting ethnic Tamils, humanitarian workers and journalists. The human rights of all citizens suffered as a result and ultimately led to the weakening of the rule of law. With the end of the civil war, the Sri Lankan Government has made little progress in providing accountability for wartime abuses. Its absence of and reluctance to ensure justice is seen as a logical culmination of decades of impunity. The importance of acknowledging historical behaviour and taking accountability for past violations will be discussed. In an analysis for paving the way to a new democracy in Sri Lanka, the main outcomes of this article are calls for accountability arising out of the government’s actions during the war; an investigation into the present state of human rights, the rule of law and finally; an examination into the political solution going forward to ensure a process of reconciliation and peaceful co-existence.     

Optimal sample size allocation for tests with multiple levels of stress with extreme value regression

In this article, we discuss the optimal allocation problem in a multiple stress levels life‐testing experiment when an extreme value regression model is used for statistical analysis. We derive the maximum likelihood estimators, the Fisher information, and the asymptotic variance–covariance matrix of the maximum likelihood estimators. Three optimality criteria are defined and the optimal allocation of units for two‐ and k‐stress level situations are determined. We demonstrate the efficiency of the optimal allocation of units in a multiple stress levels life‐testing experiment by using real experimental situations discussed earlier by McCool and Nelson and Meeker. Monte Carlo simulations are used to show that the optimality results hold for small sample sizes as well. © 2006 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

反舰导弹机动与导引配合的弹道设计研究

传统反舰导弹的末端机动与导引是分别进行的,这使得突防效果的提升受限。为了达到提高突防概率和实现高精度导引的双重目的,需要在导弹的末段实现机动与导引协同配合的设计。利用弹目之间的几何关系,规划设计了根据弹目实时连线进行自适应蛇行机动的程序参考信号。整个设计可以看作比例导引法与蛇行机动的复合,利用的信号包括实测的雷达方位角信号、弹目距离与预先设计好的时间指令。     

再论加强公安执法人员的法治观念

法制现代化是中国当前重大的社会主题之一,它是一个历史的、发展的过程。公安法治建设必然对国家法制现代化进程产生重大的影响。公安机关的性质、地位和作用决定了公安执法人员必须具有正确的执法思想。而法律至上观念、权利本位观念、分权制衡观念、正当程序观念对公安执法人员正确执法思想的形成有着直接的影响。     

常规导弹封锁机场跑道效能准则问题研究

由于没有考虑跑道的可维修性,当前所使用的跑道失效率指标具有较大局限性。如何从实战特点出发选取效能指标成为常规导弹封锁机场跑道作战效能评估的关键。首先分析了跑道抢修能力、抢修策略、道面上弹坑数及弹坑分布均匀程度对跑道恢复起降能力的影响,提出用跑道起降能力作为效能指标选取的依据,并就跑道起降能力的量化与效能指标体系的构建进行了研究,然后用实例对所建效能指标进行了验证。结果表明,该效能指标模型比之跑道失效率指标严格的定义更加贴近作战的实际情况,使用该指标能够满足常规导弹打击机场跑道作战效能评估、火力需求预测及打击方案选优等需要。
