体育教学与学生性格培养

体育运动对人的个性的形成有着直接和间接的影响，经常有计划地从事体育运动，对人们良好性格的形成能产生巨大的影响．在体育教学中注意培养学生的意志力、勇敢性、自制力、果断性、顽强性和纪律性等，对学生性格的发展起着重要的作用。     

基于规则矩阵的数值化推理算法

何华灿等于１９９４年首次提出了数值化推理技术的概念，给出了一种基于规则矩阵的数值化推理算法，它同时完成规则的激活和可信度传播计算。本文提出另一种基于规则矩阵的数值化推理算法，它先判定规则是否被激活，再进行被激活规则的可信度传播计算。这两种方法各有优缺点，适用于不同场合，可根据应用需要选择

一种可越过管内凹形障碍的双驱动多轮移动载体的研究

本文在轮式和履带式管内行走机构的基础上，提出了一种新的管内行走机构，它利用两个电机分别驱动均布在机架上的与管内壁用弹簧力封闭的两组６个行进轮，从周向来看，３组驱动轮分别均布在３组平行四边形机构上，巧妙的把轮式和履带式管内行走机构结合在一起，使机构具有很好的越障能力．该机构紧凑，驱动效率高，工作可靠，尤其适用于管内壁有内凹障碍的管内环境．     

特高压环境下OPGW耐雷性能分析

我国目前正在开展的特高压电网,由于线路参数发生变化,对OPGW的耐雷性能将提出更高的要求,在实践工程中应重点考虑。文章首先简要介绍了特高压电网的基本概念,分析了在特高压环境下OPGW在雷击性能方面与超高压环境的主要区别,并通过一些计算比较得出在特高压环境下由于引雷概率增大,则相应地提高OPGW耐雷能力的结论。     

OPGW允许的最高温度

当电力系统发生短路故障时,流过OPGW的短路电流会使OPGW发热升温。当温度超过200℃时,不但会影响OPGW的性能(光纤的着色层变硬、退色,能量损耗增大),而且易造成OPGW发生鸟笼现象、断股现象。短路电流容量是衡量OPGW温度特征的尺码,文章介绍了有关标准,对各种典型结构的OPGW进行了短路电流容量和温升关系的分析,从而说明设计和选用OPGW时,遵循OPGW标准规定的重要意义。     

Striping and Scheduling for Large Scale Multimedia Servers

When designing a multimedia server, several things must be decided: which scheduling scheme to adopt, how to allocate multimedia objects on storage devices, and the round length with which the streams will be serviced. Several problems in the designing of large-scale multimedia servers are addressed, with the following contributions: (1) a striping scheme is proposed that minimizes the number of seeks and hence maximizes the performance; (2) a simple and efficient mechanism is presented to find the optimal striping unit size as well as the optimal round length, which exploits both the characteristics of VBR streams and the situation of resources in the system; and (3) the characteristics and resource requirements of several scheduling schemes are investigated in order to obtain a clear indication as to which scheme shows the best performance in realtime multimedia servicing. Based on our analysis and experimental results, the CSCAN scheme outperforms the other schemes. It is believed that the results ar

Testing process performance based on capability index Cpk with critical values

Process capability index C_pk has been widely used in the manufacturing industry as a process performance measure. In this paper, we investigate the natural estimator of the index C_pk, and show that under the assumption of normality its distribution can be expressed as a mixture of the chi-square and the normal distributions. We also implement the theory of hypothesis testing using the natural estimator of C_pk, and provide efficient Maple programs to calculate the p-values as well as the critical values for various values of -risk, capability requirements, and sample sizes. The behavior of the p-values and critical values as functions of the distribution parameters are investigated to obtain tight critical values for reliable testing. Based on the test, we develop a simple and practical procedure for in-plant applications. The practitioners can use the proposed procedure to determine whether their process meets the preset capability requirement, and make reliable decisions.
