Inversion formula and uncertainty inequalities for the Weinstein-type Segal–Bargmann transform

Integral transforms and special functions, 2023
In 1961, Bargmann introduced the classical Segal–Bargmann transform and in 1984, Cholewinsky introduced the generalized Segal–Bargmann transform. These two transforms are the aim of many works, and have many applications in mathematics. In this paper, we

Inversion formula for the windowed linear canonical transform

Applicable Analysis, 2022
We study the inversion formula for recovering a signal from its windowed linear canonical transform. Different from the known inversion formula, where a double integral is invoked, we show that every signal can be recovered from its windowed linear ...

3-D Cross-Gradient Joint Inversion Method for Gravity and Magnetic Data With Unstructured Grids Based on Second-Order Taylor Formula: Its Application to the Southern Greater Khingan Range

IEEE Transactions on Geoscience and Remote Sensing, 2022
The cross-gradient joint inversion of gravity and magnetic data is a commonly used way, which requires dividing the subsurface into closely arranged cells with structured or unstructured grids to solve the physical properties of the discrete subsurface ...

Inversion formula for the problem of integral geometry on families of parabolas

IEEE/OES Working Conference on Current Measurement Technology, 2021
In 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.

Post‐stack impedance blocky inversion based on analytic solution of viscous acoustic wave equation

Geophysical Prospecting, 2020
The 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.

A Practical Method for Computation of Laplace Inverses by Post–Widder’s Formula

National Academy Science Letters, 2017
In 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.

EXPLICIT BAYESIAN SOLUTION FOR INCOMPLETE PRE-POST TEST PROBLEMS USING INVERSE BAYES FORMULAE

Communications in Statistics - Theory and Methods, 2001
Pre-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.

The computation of the probability density and distribution functions for some families of random variables by means of the Wynn-ρ accelerated Post-Widder formula

Communications in statistics. Simulation and computation, 2020
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 ...

Fractional Fourier Analysis Using the Möbius Inversion Formula

IEEE Transactions on Signal Processing, 2019
Compared with the Fourier analysis, the fractional Fourier analysis is more suitable to process linear frequency modulation type non-stationary functions.
