In this article, a new four-parameter lifetime model called the beta generalized inverse Rayleigh distribution (BGIRD) is defined and studied. Mixture representation of derived. Curve’s behavior probability density function, reliability hazard function are Next, we derived quantile median, mode, moments, harmonic mean, skewness, kurtosis. addition, order statistics mean deviations about median ...

a comparison of buckling analysis of the nanoplate and nanocomposite plate with central square hole embedded in winkler foundation is presented in this article. in order to enhance mechanical properties of nanoplate with central cut out, carbon nano tubes (cnts) are applied as uniform distribution (ud) through thickness direction. in order to define the shape function of plate with square cut o...

Recently, Rayleigh distribution has received considerable attention in the statistical literature. In this paper, we consider the point and interval estimation of the functions of the unknown parameters of a two-parameter Rayleigh distribution. First, we obtain the maximum likelihood estimators (MLEs) of the unknown parameters. The MLEs cannot be obtained in explicit forms, and we propose to us...

Reliability as one of main indices of quality deals with products in service. There has developed the intensive study of distribution types in the reliability theory. Ramified computing systems often have elements which are exposed to aging on output level. Lifetime of such elements is often circumscribed by the Rayleigh distribution. Elements of upper levels have lifetime circumscribed by the ...

A new system has been developed and calibrated to measure the charactristics and distribution of skylight polarization. With a series of measurements obtained, we verified that the distribution of degree and angle of skylight polarization accords well with the predictions of Rayleigh scattering. The differences of the characteristics and distribution of skylight polarization across the principa...
