Unconditional analogues of Cochran–Mantel–Haenszel tests

The Cochran–Mantel–Haenszel tests are a suite of tests that are usually defined as conditional tests, tests that assume all marginal totals are known before sighting the data. Here unconditional analogues of these tests are defined for the more usual situation when the marginal totals are not known before sighting the data.     

The Incremental Group Testing Model for Gap Closing in Sequencing Long Molecules

In this paper, we propose the incremental group testing model for the gap closing problem, which assumes that we can tell the difference between the outcome of testing a subset S, and the outcome of testing S {x}. We also give improvements over currently best results in literature for some other models.

基于浊度检测的洗衣机废水自动回收装置的设计

为回收再利用洗衣机在洗涤过程中所排的废水，设计了洗衣机废水自动回收装置，装置由浊度传感器、液位开关、水用电磁阀、潜水泵、水箱等构成。该装置可自动识别废水污浊程度，从而决定是否回收储存起来。经简易处理的回收废水类似于q-水，可用于马桶及地面的冲洗，这对于水资源的节约利用、绿色住宅建筑设施设计具有一定的参考意义，同时也具有一定的经济效益。     

法家的＂以术治吏＂与企业的刚性管理

从人性的高度上揭示法家"以术治吏"的理论基础是本文的主要特点之一.与此同时,还详细论述了法家的"察奸之术"、"防奸之术"和"除奸之术"等,并且进一步对法家"以术治吏"的刚性管理做出了客观的评价.     

Effect of equicorrelation in detecting a spurious observation

This note examines the effect of equicorrelation of the observations on Grubbs' (1950) procedure of detecting an outlier in a sample of n independent observations. It is shown that the procedure is robust, in fact the significance level remains unchanged.     

铁道车辆轮轴裂纹检测及计算

研究了轮轴嵌入部內、外侧裂纹的检测方法,给出了考虑材质差、常数补偿的裂纹径向深度计算方法,设计了以单片机为核心的便携式数据处理装置。     

电网电压瞬变叠加干扰的检测方法研究

本文在考察电网电压瞬变叠加干扰的基础上,对其检测方法作了较为详尽的方法,着重描述了实用性较强的模糊检测法并给予了研究。笔者所实现的硬件及其实测结果证这了模拟检测法在实际应用中的可行性。由于这种方法具有较“浮动窗”触发算法的硬件实现简单,成本低廉及可行性好等显著特点,特别在多路检测中则更具有优越性,因而在国内具有较高的推广价值。     

Testing for a change lit the regression matrix of a multivariate linear model

A Bayesian test procedure Is developed to test; the null hypothesis of no change In the regression matrix of a multivariate lin¬ear model against the alternative hypothesis of exactly one change The resulting test is based on the marginal posterior distribution of the change point; To illustrate the test procedure a numerical example using a bivariate regression model is considered.
