A STOCHASTIC ORDERING FOR RANDOM VARIABLES WITH APPLICATIONS

A new univariate stochastic ordering is introduced. Some characterization results for such an ordering are stated. It is proved that the ordering is an integral stochastic ordering, obtaining a maximal generator. By means of this generator, the main properties of the ordering are deduced. A method for introducing univariate stochastic orderings, suggested by the new ordering, is analysed. Relationships with other stochastic orderings are also developed. To conclude, an example of an application of the new ordering to the field of medicine is proposed.

On Empirical Processes for Ergodic Diffusions and Rates of Convergence of M-estimators

Abstract. This paper contributes to the development of empirical process theory for ergodic diffusions. We prove an entropy‐type maximal inequality for the increments of the empirical process of an ergodic diffusion. The inequality is used to study the rate of convergence of M‐estimators.     

Nonparametric estimation of the bivariate cdf for arbitrarily censored data

Right, left or interval censored multivariate data can be represented by an intersection graph. Focussing on the bivariate case, the authors relate the structure of such an intersection graph to the support of the nonparametric maximum likelihood estimate (NPMLE) of the cumulative distribution function (CDF) for such data. They distinguish two types of non‐uniqueness of the NPMLE: representational, arising when the likelihood is unaffected by the distribution of the estimated probability mass within regions, and mixture, arising when the masses themselves are not unique. The authors provide a brief overview of estimation techniques and examine three data sets.

从关联理论谈北京奥运中餐的翻译

北京奥运中餐的翻译实质是一种言语交际行为,也应遵循关联理论,即译者从原著者明示的交际行为中寻找最大关联,再把这种关联性传递给译文读者。本文通过示例阐述了北京奥运中餐的翻译中采取的语内增词引申、文外加注及隐义显译等顺应措施。     

联合约束无线传感器网络连通支配集算法

针对无线传感器网络连通支配集构建问题,基于(α,β)-tree定义了具有传输时延约束的连通支配树CDTT问题,并提出CDT算法构建有限总功率消耗的CDT-tree,同时符合传输时延约束要求。给出的分布式CDS算法分为两个阶段执行,首先基于单位圆图构建MIS,然后在双权值无向图上使用MST和SPT实现CDT算法,同时满足联合约束要求,具有O(n2)的时间和消息复杂度。理论分析和仿真结果表明提出的算法能正确地解决CDTT问题,构建联合约束的CDS。
