Inversion of the laplace transform via post—widder formula
Integral Transforms and Special Functions, 2001We construct a numerical technique to approximate the inverse Laplace transform f (t) when the transform F(s) is given analytically. The main contribution of our work is the development of a new and effective method to evaluate the coefficients of the expansion arising in the inversion formula of Post-Widder technique.

Inversion formula for the problem of integral geometry on families of parabolas
IEEE/OES Working Conference on Current Measurement Technology, 2021In this paper, we consider the problems of integral geometry on families of parabolas. We examined the application of the integral geometry problem to seismic problems.

A Practical Method for Computation of Laplace Inverses by Post–Widder’s Formula
National Academy Science Letters, 2017In this note, a novel method for parametric inversion of Laplace transforms by means of the Post–Widder formula is developed. In brief, the coefficients of the MacLaurin series equivalent of the sequence, which converges to Post–Widder’s formula at infinity, are calculated by means of the iterated Aitken transform.

Post‐stack impedance blocky inversion based on analytic solution of viscous acoustic wave equation
Geophysical Prospecting, 2020The conventional impedance inversion method ignores the attenuation effect, transmission loss and inter‐layer multiple waves; the smooth‐like regularization approach makes the corresponding impedance solution excessively smooth.

EXPLICIT BAYESIAN SOLUTION FOR INCOMPLETE PRE-POST TEST PROBLEMS USING INVERSE BAYES FORMULAE
Communications in Statistics - Theory and Methods, 2001Pre-Post test design is one of the commonly used designs in clinical trials where patients serve as their own control and the differentail effect of a treatment is assessed. The same scenario also arises in comparing pre-post test changes in either physiological variables or molecular or genetic targets.

We propose the suitable use of the Post-Widder inversion formula for Laplace transforms – coupled with the Wynn’s ρ-algorithm for accelerating sequences – in order to evaluate (up to the desired accuracy) the probability density function and the ...
