Survey on the Numerical Methods for ODE's Using the Sequence of Successive Approximations [PDF]
, 2005 Here we present the error estimations in the numerical methods for Cauchy problems corresponding to ODE’s, which use the sequence of successive approximations and quadrature rules such as trapezoidal rule and perturbed trapezoidal ...

Differential Quadrature Solution of Hyperbolic Telegraph Equation [PDF]
Journal of Applied Mathematics, 2012 Differential quadrature method (DQM) is proposed for the numerical solution of one‐ and two‐space dimensional hyperbolic telegraph equation subject to appropriate initial and boundary conditions. Both polynomial‐based differential quadrature (PDQ) and Fourier‐based differential quadrature (FDQ) are used in space directions while PDQ is made use of in ...

Remarks on mixed-integer formulations for hyper-reduction schemes in nonlinear dynamics
Advanced Modeling and Simulation in Engineering Sciences, 2020 The hyper-reduction problem for reduced-order internal forces evaluation in transient, nonlinear, explicit dynamics is reformulated, employing Mixed-Integer Programming (MIP), taking into account consistency constraints.

Differential Quadrature Solution for One-Dimensional Aquifer Flow [PDF]
Mathematical and Computational Applications, 2011 Differential Quadrature Method (DQM) has been applied to the solution of aquifer flow problems. Three examples from of each of the three one-dimensional aquifer flow equation problems, a confined aquifer flow with time dependent boundary conditions, a composite confined aquifer and an unconfined aquifer with seepage, were examined.

Design of quadrature rules for Müntz and Müntz-logarithmic polynomials using monomial transformation [PDF]
, 2009 A method for constructing the exact quadratures for Müntz and Müntz-logarithmic polynomials is presented. The algorithm does permit to anticipate the precision (machine precision) of the numerical integration of Müntz-logarithmic polynomials in terms of ...

A cases of solvability of the integral equation in quadratures
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 We consider Volterra equation with two-variable, commonly encountered in the theory of elasticity. The purpose is to find new variants of sufficient conditions for it’s solvability in explicit calculation. The reduction principle of the original equation,
