Four-scalar model and spherically symmetric solution in f(T) theory

open access: yesNuclear Physics B
In this study, we explore the realization of spherically symmetric solutions in the context of modified teleparallel gravity, particularly in f(T) theory, where T denotes the torsion scalar.

Online Signature Verification based on the Lagrange formulation with 2D and 3D robotic models

open access: yesPattern Recognition
Online Signature Verification commonly relies on function-based features, such as time-sampled horizontal and vertical coordinates, as well as the pressure exerted by the writer, obtained through a digitizer. Although inferring additional information about the writers arm pose, kinematics, and dynamics based on digitizer data can be useful, it ...

High-order Lagrange-Galerkin methods for the conservative formulation of the advection-diffusion equation

open access: yesIMA Journal of Numerical Analysis
Abstract We introduce in this paper the numerical analysis of high order both in time and space Lagrange-Galerkin methods for the conservative formulation of the advection-diffusion equation. As time discretization scheme we consider the Backward Differentiation Formulas up to order $q=5$.

On the Lagrange and Euler variational formulations of linear ideal magnetohydrodynamics

open access: yesPhysics of Plasmas
Both the Lagrangian and Eulerian variational descriptions of the flow field are employed in classical fluid mechanics. In a magnetically confined plasma, the variational formulations become more complicated due to the presence of a magnetic field and the so-called frozen-in phenomenon.

A new numerical technique to seek properties of the nonlinear oscillators

open access: yesJournal of Low Frequency Noise, Vibration and Active Control
Numerical methods are widely used in the area of nonlinear problems including differential equations. There are various integral transformations to study the frequency formulations and nonlinear solutions, but there are many types of transformations that

Specification Tests Based on Artificial Regressions [PDF]

open access: yes
Many specification tests can be computed by means of artificial linear regressions. These are linear regressions designed to be used as calculating devices to obtain test statistics and other quantities of interest.

On numerical methods for time-dependent eddy current problems for the Maxwell equations in inhomogeneous media

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2018
E-based and H-based formulations for time-dependent eddy current problems for the Maxwell equations in inhomogeneous media have been derived. The concept of generalized solutions for boundary-value problems in bounded regions for obtained systems of ...
