Although Elzaki transform is stronger than Sumudu and Laplace transforms to solve the ordinary differential equations withnon-constant coefficients, but this method does not lead to finding the answer of some differential equations. In this paper, a method is introduced to find that a differential equation by Elzaki transform can be solved?
in this paper, we present legendre wavelet method to obtain numerical solution of a singular integro-differential equation. the singularity is assumed to be of the cauchy type. the numerical results obtained by the present method compare favorably with those obtained by various galerkin methods earlier in the literature.
Here, Adomian decomposition method has been used for finding approximateand numerical solutions of nonlinear differential difference equations arising inmathematical physics. Two models of special interest in physics, namely, theHybrid nonlinear differential difference equation and Relativistic Toda couplednonlinear differential-difference equation are chosen to illustrate the validity andthe g...
a method for solving a class of weakly singular volterra integral equations is given by using the fractional differential transform method. the approximate solution of these equations is calculated in the form of a finite series with easily computable terms. while in some examples this series solution increased up to the exact closed solution, in some other examples, we can see the accuracy an...
in this paper, elzaki homotopy perturbation method is employed for solving linear and nonlinear differential equations with a variable coffecient. this method is a combination of elzaki transform and homotopy perturbation method. the aim of using elzaki transform is to overcome the deficiencies that mainly caused by unsatised conditions in some semi-analytical methods such as homotopy perturbat...
in this article we have considered a non-standard finite difference method for the solution of second order fredholm integro differential equation type initial value problems. the non-standard finite difference method and the composite trapezoidal quadrature method is used to transform the fredholm integro-differential equation into a system of equations. we have also developed a numerical met...
In this paper we present a numerical method for fuzzy differential equation of fractional order under gH-fractional Caputo differentiability. The main idea of this method is to approximate the solution of fuzzy fractional differential equation (FFDE) by an implicit method as corrector and explicit method as predictor. This method is tested on numerical examples.
در این تحقیق، هدف تعیین تنش ها و کرنش های تورمی ناشی از حفاری تونل در توده سنگ های تورمی است. این تحلیل در دو بخش انجام شده است، ابتدا با حل معادله ی دیفرانسیلی کرنش تورمی به روش تحلیلی، مقادیر آن برای نقاط اطراف تونل محاسبه شده است. سپس با حل عددی به روش اجزای محدود با استفاده از المان های ایزوپارامتریک q4، تنش ها و کرنش های ناشی از بارگذاری و حفاری، در محیط اطراف تونل محاسبه و با مقادیر نظیر ...
