چکیده

In this article, simultaneous identification of the timewise lowest and source terms in a two-dimensional (2D) parabolic equation from knowledge additional measurements is studied. Existence uniqueness solution proved by means contraction mapping on small time interval. Since problem yet ill- posed (very errors time-average temperature input may cause large output potential functions), we need to regularize solution. Hence, regularization needed for retrieval unknown terms. The 2D computationally solved using ADE scheme reshaped as non-linear optimization Tikhonov function. This numerically studied MATLAB $lsqnonlin$ subroutine. Finally, present numerical example demonstrate accuracy efficiency proposed method. Our results show that an efficient unconditionally stable reconstructing coefficients minimal data which makes inverse (IP) unique.

An inverse problem of identifying the coefficient of semilinear parabolic equation

    In this paper, a variational iteration method (VIM), which is a well-known method for solving nonlinear equations, has been employed to solve an inverse parabolic partial differential equation. Inverse problems in partial differential equations can be used to model many real problems in engineering and other physical sciences. The VIM is to construct correction functional using general Lagr...

Solving the inverse problem of determining an unknown control parameter in a semilinear parabolic equation

The inverse problem of identifying an unknown source control param- eter in a semilinear parabolic equation under an integral overdetermina- tion condition is considered. The series pattern solution of the proposed problem is obtained by using the weighted homotopy analysis method (WHAM). A description of the method for solving the problem and nding the unknown parameter is derived. Finally, tw...
