Through theoretical and empirical study,this paper finds that in one day,the frequencies of CN domains will be queried following the Zipf\'s-like distribution,however the number of requests issued from hundreds of thousands of DNS cache servers follows the stretched exponential distribution.

Statistics analysis for the circular-progressive-stress life tests under generalized exponential distribution;

The frequency computation by two-end limited lognormal distribution and generalized exponential distribution as the type of frequency curve is presented in the paper.

This paper is to give the empirical Bayes estimator of unknown shape parameter of Generalized exponential distribution with empirical Bayes method.

In this paper,a failure model of mixed generalized exponential distributions(MGED) is considered and its estimators for all unknown parameters based on type-I and type-II censored data are obtained by means of EM algorithm.

In this paper a failure model of mixed generalized exponential distributions(MGED) is introduced and its estimators for all unknown parameters under full data are obtained by means of EM algorithm.

Used the interpolation to obtain the droplet the diameter distribution map and calculated the droplet diameters distribution index.

Terrain niche index was used to describe the regional terrain difference and nondimensio-nal distribution index was used to quantitatively analyze the spatial distribution characteristics based on the spatial information of landscape components.

The terrain factors(elevation,slope and aspect) and distribution index was overlapped to quantitatively analyse the region soil erosion,which could study the soil erosion spatial distribution from terrains factors(elevation,slope and aspect).

A Bayesian analysis for non-failure data of exponential distribution;

Γ-minimax estimation for exponential distribution parameter;

Censored SPOT method for reliability index verification under exponential distribution;
