the probability density functions fitting to the discrete probability functions has always been needed, and very important. this paper is fitting the continuous curves which are probability density functions to the binomial probability functions, negative binomial geometrics, poisson and hypergeometric. the main key in these fittings is the use of the derivative concept and common differential ...

Numerical solutions obtained by the Meshless Local Petrov-Galerkin (MLPG) method are presented for two dimensional steady-state heat conduction problems. The MLPG method is a truly meshless approach, and neither the nodal connectivity nor the background mesh is required for solving the initial-boundary-value problem. The penalty method is adopted to efficiently enforce the essential boundary co...

in 1914, showing a decidedly lower transmission of radiation through the water cell, in the case of Venus and Saturn. The intensity of the planetary radiation increases with decrease in the density of the surrounding atmosphere and (as interpreted from the water cell transmissions) in per cent of the total radiation emitted, is as follows: Jupiter (0), Venus (5), Saturn (15), Mars (30) and the ...

<b>Background:</b> Pulsed field ablation (PFA) is a new type of physical energy source in the fields tumor and atrial fibrillation ablation, based on irreversible electroporation with non-thermal, clear boundaries, selective killing, rapid advantages. PFA induces changes electrical conductivity zone, which can be described by step function used to predict zone. However, current rese...

Three kinds of fragile points methods based on Petrov-Galerkin weak-forms (PG-FPMs) are proposed for analyzing heat conduction problems in nonhomogeneous anisotropic media. This is a follow-up the previous study original FPM symmetric Galerkin weak-form. The trial function piecewise-continuous, written as local Taylor expansions at points. A modified radial basis function-based differential qua...

Let r be an A-stable rational approximation of the exponential function of order q ≥ 1 and let t > 0. It is shown that the inverse LaplaceStieltjes transforms αn : s→ αn∗(ns t ) of rn(z) := r n( tz n ) converge in Lp(R+) to the Heaviside function Ht with a rate of t1/pn−1/2p(ln(n+1))1−1/p. Moreover, for 0 ≤ k ≤ q, the k-th antiderivatives of αn converge in Lp(R+) to the k-th antiderivative of t...
