一种减小数字阵雷达非线性相关的方法

对非线性阵列相关问题进行分析,提出了一种新的非线性去相关技术来提高数字阵瞬时动态范围。该方法主要在接收机中利用了方向相反的两级相移,第一级在接收机前端,第二级在数字部分。理论分析表明利用该方法能有效地去相关杂散、互调失真等各种非线性,从而最大限度地提高系统的瞬时动态范围。仿真结果验证了该方法的有效性。     

现代信息技术的发展对远程教育的影响

现代远程教育作为一种利用现代信息技术发展高素质教育的教育方式正以前所未有的速度向前发展,并在许多国家的教育系统中脱颖而出,起着越来越重要的作用。人们以极大的兴趣和热忱关注着现代远程教育的发展,希望这种非常规教育能给教育的改革注入新的活力,开辟更为广阔的天地。     

关于检察机关提起民事诉讼的几点思考

检察机关能否代表国家提起民事诉讼,我国法律没有明确规定,实践中各地检察机关和人民法院的做法各不相同。立法应尽快明确赋予检察机关代表国家和公共利益提起民事诉讼的权力,精心设置人民法院审理检察机关提起民事诉讼案件的相关程序等问题。     

论远程教育中多媒体教学资源的应用效果

分析和评价了我国现代远程教育多媒体教学资源的现状和应用效果,针对多媒体教学资源中存在的问题,提出以学生为中心的理念,对多媒体教学资源进行开发设计;用开放性原则来进一步完善多媒体教学资源的建设;从最优化组合的要求对现有的多媒体教学资源进行整合。     

厚生与元康文学的词采繁富

元康时期,讲求辞藻的繁富、英华膏泽成为文学创作的潮流,这与文学的自觉和元康文人的逞才不无关系,但也不能忽视那个时代由个体生命的觉醒而带来的追求感性生命价值的风尚的影响.     

网上超市的区域化战略评析

随着电子商务的蓬勃发展,网上超市在零售业中的地位日益显著,但物流瓶颈仍然是我国目前发展网上超市的最大问题.作者从战略的角度,以物流范围大小为主要区别特征将众多网上超市的经营战略划分全程战略和区域战略模式,对两类战略进行了区域、物流、经营范围和成本、消费兼容性、促销等方面的优劣分析,认为区域化战略是突破物流瓶颈,发展我国网上超市的有效途径.     

Shannon Information Properties of the Endpoints of Record Coverage

This paper addresses the largest and the smallest observations, at the times when a new record of either kind (upper or lower) occurs, which are it called the current upper and lower record, respectively. We examine the entropy properties of these statistics, especially the difference between entropy of upper and lower bounds of record coverage. The results are presented for some common parametric families of distributions. Several upper and lower bounds, in terms of the entropy of parent distribution, for the entropy of current records are obtained. It is shown that mutual information, as well as Kullback–Leibler distance between the endpoints of record coverage, Kullback–Leibler distance between data distribution, and current records, are all distribution-free.     

A note on maximum Z-scores for control charts for individuals

Control chart limits are often constructed retrospectively based on a sequence of individual measurements. It is shown that the usual control chart limits cannot be crossed for small numbers of measurements.     

Two stage multiple comparison procedures based on the studentized range

Stein’s (1945) two sample approach and Tukey’s T-Method of multiple comparisons (see e.g. Miller, 1966, Ch. 2) are combined to obtain fixed width simultaneous confidence intervals and simultaneous test procedures of predetermined Type I and Type II error levels, for all contrasts, in a one way layout. The necessary constants for implementing the two stage procedure are obtained under a least favorable configuration of the parameters. This provides the required protection of the null and alternative hypotheses under any configuration of parameters. A table is provided for some selected designs and error levels and an example is given to illustrate certain features of the new procedure.
