基于自适应累量算法的舰船轴频电场信号检测方法

提出一种新的舰船轴频电场信号检测方法.该方法利用高阶累量对高斯噪声的抑制作用,首先使用基于自适应累量算法的FIR滤波器对接收信号进行滤波消噪处理,以提高信噪比;然后再对滤波输出信号进行滑动功率谱检测.实测数据处理结果表明了该方法的稳健性和有效性.     

Supply chain coordination with shelf‐space and retail price dependent demand and heterogeneous retailers

We consider supply chain coordination in which a manufacturer supplies some product to multiple heterogeneous retailers and wishes to coordinate the supply chain via wholesale price and holding cost subsidy. The retail price is either exogenous or endogenous. The market demand is described by the market share attraction model based on all retailers'shelf‐spaces and retail prices. We obtain optimal solutions for the centralized supply chain, where the optimal retail pricing is a modified version of the well‐known cost plus pricing strategy. We further get feasible contracts for the manufacturer to coordinate the hybrid and decentralized supply chains. The manufacturer can allocate the total profit free to himself and the retail market via the wholesale price when the retail price is exogenous, but otherwise he cannot. Finally, we point out that different characteristics of the retail market are due to different powers of the manufacturer, and the more power the manufacturer has, the simpler the contract to coordinate the chain will be. © 2010 Wiley Periodicals, Inc.

试论经济力量向军事力量的转化

国家经济力量是军事力量的唯一源泉,军队的战斗力大小是军事力量强弱的重要标志,提高战斗力是军队一切工作的核心。但是,经济力量并不等于就是军事力量和战斗力,要把经济力量变为军队的战斗力还要经过一系列的转化过程。其整个转化过程可分为三个步骤,即经济力量向保障力量要素的转化;保障力量要素向保障能力的转化;保障能力向战斗力的转化。认真研究这些转化过程和转化环节,掌握其转化途径、方法和转化机制,对于促进和加快转化速度,提高转化效率和军队战斗力,具有十分重要的现实意义,是加强质量建军,实现两个根本转变和做好军事斗争准备的关键。

高功率微波对YBCO超导材料的改性

用固相反应法制备了123相YBCO超导块材。利用超导电性（Tc）测量、扫描电镜（SEM）等方法研究了高功率微波加载及退火处理对YBCO样品的影响。电阻－温度关系曲线表明,处理后的样品在超导起始转变温度Tco≈90K处由半导体型向超导转变,超导转变宽度△T增大。SEM结果显示,晶粒大大细化。作者认为,由于高功率微波对样品的瞬时高压作用,在样品中引入了阻碍磁通蠕动的钉扎中心,同时,退火处理改善了晶粒之间的弱连接,为提高临界电流密度Jc创造了条件。

Optimal material control in an assembly system with component commonality

Allocation of scarce common components to finished product orders is central to the performance of assembly systems. Analysis of these systems is complex, however, when the product master schedule is subject to uncertainty. In this paper, we analyze the cost—service performance of a component inventory system with correlated finished product demands, where component allocation is based on a fair shares method. Such issuing policies are used commonly in practice. We quantify the impact of component stocking policies on finished product delays due to component shortages and on product order completion rates. These results are used to determine optimal base stock levels for components, subject to constraints on finished product service (order completion rates). Our methodology can help managers of assembly systems to (1) understand the impact of their inventory management decisions on customer service, (2) achieve cost reductions by optimizing their inventory investments, and (3) evaluate supplier performance and negotiate contracts by quantifying the effect of delivery lead times on costs and customer service. © 2001 John Wiley & Sons, Inc.
