Solvability of the Goursat problem in quadratures
, 2020 We find new variants of Goursat problem solution in quadratures on the basis of the combination of the Riemann method and the cascade integration. The results are applied to two Volterra equations with particular integrals.

Non-integrability by discrete quadratures
, 2014 International audienceWe give a necessary condition for integrability by discrete quadratures of systems of difference equations: the discrete variational equations along algebraic solutions must have virtually solvable Galois groups.

Integration quadratures in discretization of stochastic programs [PDF]
, 2002 Because of its simplicity, conditional sampling is the most popular method for generating scenario trees in stochastic programming. It is based on approximating probability measures by empirical ones generated by random samples.

Advanced Science, EarlyView.This paper reveals internal resonance mismatch‐controlled dissipative bistability collapse in a coupled micromechanical resonator. Tuning δIR changes both internal‐mode amplitude and phase‐dependent feedback. For negative mismatch, Duffing bistability survives.

Numerical Solutions of the Generalized Burgers‐Huxley Equation by a Differential Quadrature Method [PDF]
Mathematical Problems in Engineering, 2009 Numerical solutions of the generalized Burgers‐Huxley equation are obtained using a polynomial differential quadrature method with minimal computational effort. To achieve this, a combination of a polynomial‐based differential quadrature method in space and a low‐storage third‐order total variation diminishing Runge‐Kutta scheme in time has been used ...

Iterative methods for solving Ambartsumian’s equations. Part 1
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2021 Background. Ambartsumian’s equation and its generalizations are one of the main integral equations of astrophysics, which have found wide application in many areas of physics and technology. An analytical solution to this equation is currently unknown,

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.

Quadrature solution of ordinary and partial differential equations
Mathematical and Computer Modelling, 1988 An entirely new alternative orthogonal polynomial (or Bellman-type) quadrature method is presented for the solution of ordinary and partial differential equations. The quadrature method, like finite difference and finite element methods, obtains an approximate solution in terms of unknown nodal values of the dependent variable(s), but, like the ...

Computational solutions for Eikonal equation by differential quadrature method
Alexandria Engineering Journal, 2022 This article presents an efficient method to solve of Eikonal equation by the new differential quadrature method. The purpose of this article is to obtain the accuracy and performance method for the Eikonal equation. We introduce a novel grid points to reduce errors and compared them on different issues to accelerate convergence.
