Linguistic Inversion and Numerical Estimation [PDF]

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.

Three-dimensional inversion analysis of transient electromagnetic response signals of water-bearing abnormal bodies in tunnels based on numerical characteristic parameters

open access: yesMathematical Biosciences and Engineering, 2023
The transient electromagnetic inversion of detection signals mainly depends on fast inversion in the half-space state. However, the interpretation results have a certain degree of uncertainty and blindness, so the accuracy and applicability of the three ...

Stokes' Problems for an Incompressible Couple Stress Fluid

open access: yesNonlinear Analysis, 2008
Stokes’ first and second problems for an incompressible couple stress fluid are considered under isothermal conditions. The problems are solved through the use of Laplace transform technique.

A multiscattering series for impedance tomography in layered media [PDF]

open access: yes, 1999
We introduce an inversion algorithm for tomographic images of layered media. The algorithm is based on a multiscattering series expansion of the Green function that, unlike the Born series, converges unconditionally.

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

Combined analysis of transient delay characteristics and delay autocorrelation function in the Geo(X)/G/1 queue [PDF]

open access: yes, 2012
We perform a discrete-time analysis of customer delay in a buffer with batch arrivals. The delay of the kth customer that enters the FIFO buffer is characterized under the assumption that the numbers of arrivals per slot are independent and identically ...

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
