Designing a Bayesian Regularization Approach to Solve the Fractional Layla and Majnun System

open access: yesMathematics, 2023
The present work provides the numerical solutions of the mathematical model based on the fractional-order Layla and Majnun model (MFLMM). A soft computing stochastic-based Bayesian regularization neural network approach (BRNNA) is provided to investigate

Gas-liquid mass transfer with parallel reversible reactions—I. Absorption of CO2 into solutions of sterically hindered amines [PDF]

open access: yes, 1989
A numerical method developed by Verteeg (1989, Chem. Engng Sci.44, 2295–2310; 1990, Chem Engng Sci.45, in press) is applied to some specific problems in gas—liquid mass transfer. The experimental results of Chakraborty (1986, Chem. Engng Sci.41, 997–1003)

High-Performance Computational Method for an Extended Three-Coupled Korteweg–de Vries System

open access: yesAxioms, 2023
This paper calculates numerical solutions of an extended three-coupled Korteweg–de Vries system by the q-homotopy analysis transformation method (q-HATM), which is a hybrid of the Laplace transform and the q-homotopy analysis method.

On the Effect of Constraint Enforcement on the Quality of Numerical Solutions in General Relativity [PDF]

open access: yes, 2001
In Brodbeck et al 1999 it has been shown that the linearised time evolution equations of general relativity can be extended to a system whose solutions asymptotically approach solutions of the constraints. In this paper we extend the non-linear equations

Numerical Solutions of Inflating Higher Dimensional Global Defects [PDF]

open access: yes, 2005
We find numerical solutions of Einstein equations and scalar field equation for a global defect in higher dimensional spacetimes ($\geq 6$). We examine in detail the relation among the expansion rate $H$ and the symmetry-breaking scale $\eta$ and the ...

A Numerical Analysis to the {$\pi$} and {K} Coupled--Channel Scalar Form-factor [PDF]

open access: yes, 2000
A numerical analysis to the scalar form-factor in the $\pi\pi$ and KK coupled--channel system is made by solving the coupled-channel dispersive integral equations, using the iteration method. The solutions are found not unique.

Consideration of damping in a continuous medium using the rod approximation by A.R. Rzhanitsyn

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2023
The work is focused on creating a method for accounting of internal friction, which provides frequency independence, considers the dependence of internal friction on the level of the stress state, and is suitable for physically nonlinear tasks at large ...

Geodetic Measurements and Numerical Models of Deformation at Coso Geothermal Field, California, USA, 2004–2016

open access: yesRemote Sensing, 2020
We measure transient deformation at Coso geothermal field using interferometric synthetic aperture radar (InSAR) data acquired between 2004 and 2016 and relative positions estimated from global positioning system (GPS) to quantify relationships between ...
