Computer-Aided Numerical Inversion of Laplace Transform

open access: yesActive and Passive Electronic Components, 2000
This paper explores the technique for the computer aided numerical inversion of Laplace transform. The inversion technique is based on the properties of a family of three parameter exponential probability density functions.

The accurate numerical inversion of laplace transforms [PDF]

open access: yes, 1976
Inversion of almost arbitrary Laplace transforms is effected by trapezoidal integration along a special contour. The number n of points to be used is one of several parameters, in most cases yielding absolute errors of order 10-7 for n = 10, 10-11 for n

Joint geoacoustic inversion based on Pearson correlation coefficient constraints [PDF]

open access: yesJASA Express Letters, 2023
This Letter proposes a joint geoacoustic inversion method for modal group velocity dispersion and amplitudes of waveform by incorporating a Pearson correlation constraint. Numerical simulations show that this joint inversion leads to improved geoacoustic

Unique identification of fractional orders in the fractional mobile–immobile solute transport system

open access: yesApplied Mathematics in Science and Engineering, 2023
This article deals with a fractional mobile–immobile solute transport system in porous media and an inverse problem of identifying the fractional orders by the additional measurements at one interior point.

RESEARCH OF TEMPERATURE PROFILES IN THE WELL IN THE COURSE OF PUMPING LIQUID ON THE BASIS OF NUMERICAL INVERSION OF ISEGER

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2017
The analysis of a temperature profile in the trunk of a vertical well when pumping liquid was carried out. The paper describes the application of an algorithm of the inverse numerical transformation with use of Gaussian quadratures (Iseger's method) to a

Different Numerical Inversion Algorithms of the Laplace Transform for the Solution of the Advection-Diffusion Equation with Non-local Closure in Air Pollution Modeling

open access: yesTrends in Computational and Applied Mathematics, 2018
In this paper, a three-dimensional solution of the steady-state advection-diffusion equation is obtained applying the Generalized Integral Advection Diffusion Multilayer Technique (GIADMT), considering non-local closure for turbulent flow. Two different

Linguistic Inversion and Numerical Estimation

open access: yesJournal of Numerical Cognition, 2020
Number line estimation (NLE) performance is usually believed to depend on the magnitudes of presented numerals, rather than on the particular digits instantiating those magnitudes.

Run up flow of a couple stress fluid between parallel plates

open access: yesNonlinear Analysis, 2010
Consider the flow of an incompressible fluid between two parallel plates, initially induced by a constant pressure gradient. After steady state is attained, the pressure gradient is suddenly with drawn while the plates are impulsively started ...
