This paper introduces a new distribution named Exponential Modified Weibull logistic distribution. generalizes the following distributions: (1) Linear Failure Rate Logistic Distribution, (2) (3) Rayleigh (4) where failure rate, Weibull, and exponential distributions are most used for analyzing lifetime data. The properties of derived that include expressions rthmoment, characteristic function q...

We introduce the class of strongly Rayleigh probability measures by means of geometric properties of their generating polynomials that amount to the stability of the latter. This class contains e.g. product measures, uniform random spanning tree measures, and large classes of determinantal probability measures and distributions for symmetric exclusion processes. We show that strongly Rayleigh m...

We study miscible Rayleigh-Taylor (RT) fingering instability in two-dimensional homogeneous porous media, which the fluid density varies non-monotonically as a function of solute concentration such that maximum lies interior domain, thus creating stable and an unstable gradients evolve time. With help linear stability analysis (LSA) well nonlinear simulations effects on RT fingers are investiga...

Experimentally determined natural frequencies and modes shapes are presented for an elastically point-supported isotropic plate with attached masses under impulsive loading. These results are compared to frequencies and to modes shapes determined from the Rayleigh–Ritz method and a finite element analysis using COMSOL. Accelerometers mounted at three locations on the plate, provide input for ME...

20 LLE Review, Volume 73 In recent years, several authors1–14 have studied the linear growth of the Rayleigh–Taylor (RT) instability in ablation fronts accelerated by laser irradiations. The determination of the instability growth rate is crucial to the success of inertial confinement fusion (ICF)15,16 because an excessive distortion of the front could lead to a severe degradation of the capsul...

in this study, we considered some competitive learning methods which include hard competitive learning (hcl) and soft competitive learning (scl) with/ without fixed network dimensionality for reliability analysis in microarrays. in order to have a more extensive view, and keeping in mind that competitive learning methods aim at error minimization or entropy maximization (different kinds of func...

in this work, the steady and laminar mixed convection of nanofluid in horizontal concentric annulus withrotating inner cylinder is investigated numerically. the inner and outer cylinders are kept at constanttemperature ti and to respectively, where ti>to. the annular space is filled with alumina-water nanofluid.the governing equations with the corresponded boundary conditions in the polar coord...

In uid ow problems understanding frequently is attained by studying very simpliied models. This paper presents a systematic way of generating such models, the techniques involved are inspired by numerical analysis. First we illustrate the process by constructing a simple model of Rayleigh-B enard convection which gives a remarkably good estimate of the critical Rayleigh number and the correspon...

A critical review of the heat transfer data available in the literature for free convection from upwardfacing heated rectangular plates is conducted. The review is organized in the form of a table, so as to give the reader the opportunity to compare the dimensionless correlating equations presented, and the conditions under which the heat transfer data were obtained. A comparative survey of the...
