新形势下企业标准化工作创新的思考

“十一五期间,企业标准化,如何适应当前的形势,适应改革发展要求,创新标准化管理,借企业改革改制之势,剔除不适应企业经营发展的部分,强化管理职能,更好地为生产经营服务,从而充分发挥标准化在企业的基础管理作用,为企业和社会赢得更好的经济效益和社会效益,针对这些问题,作者根据自己多年从事标准化工作的经验提出了自己的看法。     

应用Origin剔除弹药实验数据中的异常值

提出了一种应用肖维勒（Chauvenet）准则和Origin数据分析软件剔除弹药实验数据异常值的方法。     

等残差卡尔曼滤波器组算法的无人机控制故障诊断

提出了一种等残差卡尔曼滤波器组算法,它只需要单个卡尔曼滤波器的残差和状态估计及其线性变换,就可得到与标准的多模自适应滤波算法等价的残差,因此可以有效地减少计算量和计算时间.将此算法应用于某无人机控制系统的故障诊断,仿真结果验证了该方法的有效性.     

模糊AHP的舰机协同对潜搜索方式优选

战术背景下的多目标方案选择是战术行动的关键,且具有一定的不确定性和模糊性。从分析舰机协同对潜搜索战术方法出发,针对四种搜索方式的不同特点和优劣,研究了基于模糊层次分析法的搜索方案优化选择方法。根据选取的作战指标对搜索方式进行了仿真,并计算了各方案相对于准则的权重并对其进行排序,得出了结论,验证了方法的可行性和有效性。探讨的舰机协同对潜搜索方式优选方法及得出的结论,对实际反潜战的指挥决策有一定的应用价值。     

加强党委民主集中制建设重在提高落实各项基本制度质量

坚持和落实民主集中制各项基本制度,是维护集体领导、加强党委民主集中制建设的根本性措施.各级党委应当在深化认识、全面落实基本制度上下功夫,在纠偏正向、解决影响基本制度落实的难点问题上求突破,在强化监督、确保基本制度正确执行上见成效,在抓住关键、发挥书记组织落实基本制度的主导作用上立责任.     

基于改进层次分析法的对地攻击方案优选决策

应用改进层次分析法,研究了对地攻击方案优选决策问题.在分析直升机装备火箭武器对地攻击时影响任务完成的战技术指标的基础上,建立了攻击方案的优选层次结构模型.阐述了改进后的层次分析法的具体分析步骤,以及相比传统层次分析法的优越性,并通过实例计算证明了改进层次分析法是简便的、科学的,该评判方法为多目标决策优选问题提供了科学的...     

The knapsack problem with a minimum filling constraint

We study a knapsack problem with an additional minimum filling constraint, such that the total weight of selected items cannot be less than a given threshold. The problem has several applications in shipping, e‐commerce, and transportation service procurement. When the threshold equals the knapsack capacity, even finding a feasible solution to the problem is NP‐hard. Therefore, we consider the case when the ratio α of threshold to capacity is less than 1. For this case, we develop an approximation scheme that returns a feasible solution with a total profit not less than (1 ‐ ε) times the total profit of an optimal solution for any ε > 0, and with a running time polynomial in the number of items, 1/ε, and 1/(1‐α). © 2012 Wiley Periodicals, Inc.

MILITARY EXPENDITURE AND UNEMPLOYMENT RATES: GRANGER CAUSALITY TESTS USING GLOBAL PANEL DATA

This paper investigates the empirical relationships between military expenditure and unemployment rates. A set of global panel data on 46 countries is utilized, and a panel data version of the Granger causality test is applied. The results indicate that there is little evidence of the causality running from unemployment to military expenditure regardless of how we measure military spending and determine group countries. In contrast, the causality running from military expenditure to unemployment receives empirical support if military expenditure is measured in terms of its share of GDP and if data are taken from middle‐ and low‐income countries or non‐OECD countries.     

THE SECURITY IMPLICATIONS OF CHINA'S NUCLEAR ENERGY EXPANSION

Nuclear energy is an integral part of China's energy strategy and will increasingly contribute to China's total energy supply. China has more than twenty civilian facilities, including power reactors, mines, and enrichment plants, to support its nuclear power program. As China operates more nuclear plants, more nuclear materials will be produced and stockpiled, and more nuclear facilities will be spread around the country. To ensure that this expanded network of nuclear facilities does not increase the risk that nuclear materials will be diverted or become the target of attack, China will need to develop more reliable domestic nuclear security strategies. China is also poised to become a major exporter of nuclear energy technology. China has committed to keeping nuclear technologies out of the hands of dangerous states and/or sub-state organizations, but in order to fulfill its nonproliferation obligations as well as its treaty-based commitment to share nuclear technologies, China will need to strengthen nuclear export controls and practices. This report examines and evaluates security measures at Chinese civilian nuclear power plants and suggests ways to improve them. It also reviews current export control policies and systems, identifies likely challenges to the expanding nuclear sector, and proposes possible solutions.
