人工智能技术在计算机网络教学中的运用

计算机辅助教学以它的易操作性、便携性、易修改以及易保存性受到越来越多的教师的亲睐。但是,计算机辅助教学也有着它的问题,缺乏人工智能性是其最显著的缺陷之一,结合计算机人工智能技术的应用进行了探讨。     

Comments on the special issue of communications in statistics (vol.a8, no. 10) concerned with weather modification experiments

As stated by the Editors of the Special Issue. It was complied with reference to two of my statements; that much of the current weather modification literature is slanted and unreliable. and(2) that progress in the building of a reliable weather modification technology requires an interdisciplinary study of as many completed cloud seeding experiments as possible. The material published in the Special Issue relates to two completed experiments, the Tasmania and the Israeli experiments. It is shown that a realistic appraisal of a completed experiment requires a prolonged effort, including an examination of quite a few relevant publications and, on occasion, Some numerical work on published raw data. It appears that an interdisciplinary reanalysis of the Tasmania experiment can contribute to the development of a reliable cloud seeding technology.     

高校团建改革与计算机信息化管理

新世纪的高校团建将面临教育观念市场化变革,学生流动性增强,成分多样,团工负荷倍增与团机构却要精简等诸多问题。高校团建改革必须坚持超前、服务、便捷、开放、交叉性原则,立足于信息化、制度化、活动、寓载式建团方向,实行社区、社团、专业课程、专题活动建团新模式与传统的班级建团模式并举策略。并注意解决好电子注册、团费交纳管理、团员奖惩情况记录、信息汇总、网络安全性等团建新模式所必需的计算机信息化管理技术问题。     

Assessing robustness of crossover designsto subjects dropping out

In some crossover experiments, particularly in medical applications, subjects may fail to complete their sequences of treatments for reasons unconnected with the treatments received. A method is described of assessing the robustness of a planned crossover design, with more than two periods, to subjects leaving the study prematurely. The method involves computing measures of efficiency for every possible design that can result, and is therefore very computationally intensive. Summaries of these measures are used to choose between competing designs. The computational problem is reduced to a manageable size by a software implementation of Polya theory. The method is applied to comparing designs for crossover studies involving four treatments and four periods. Designs are identified that are more robust to subjects dropping out in the final period than those currently favoured in medical and clinical trials.

随机-无标度统一混合演化网络模型

根据实际网络的特点,提出了一个随机-无标度统一混合演化网络模型.通过引入一个调节参数p将随机演化网络与(Barabási-Albert)无标度网络统一起来.理论计算和计算机模拟表明,当调节参数p从1变化到0时,网络结构实现了从随机演化网络到BA无标度网络的连续过渡.
