Autor: Baydaa Khaleel Mostafa, Duaa Jasim, Athraa Falih Hasan, Ibtihal Thabit Jameel, Fatima M. ABOUD

Publikováno v: Academic Science Journal, Vol 2, Iss 1 (2024)

In this article a fourth order differential boundary value problem is solved using a mesh less collocation method. The efficiency of the proposed methods is illustrated by solving problems with some examples of a polynomial and Non polynomial exact s

Solving Inverse Cauchy Problems of the Helmholtz Equation Using Conjugate Gradient Based-Method: BICG, BICGSTAB And PCG

Autor: Ibtihal Thabit Jameel, Athraa Falih Hasan, Duaa Jasim, Fatima M. Aboud

Publikováno v: Academic Science Journal, Vol 1, Iss 4 (2023)

An inverse Cauchy problem on an under-specified portion of the boundary of a twodimensional domain occupied by a material satisfying Helmholtz-type equations from additional Cauchy data on the remaining accessible portion of the boundary has been con

Polynomial Approximation of an Inverse Cauchy Problem for Modified Helmholtz Equations

Autor: Athraa Falih Hasanl, Duaa Jasim, Ibtihal Thabit Jameel, Baydaa Khaleel Mostafa, Fatima M. Aboud

Publikováno v: Academic Science Journal, Vol 1, Iss 2 (2023)

In this paper, an inverse problem for the modified Helmholtz equation arising in heat conduction in the fin is considered. The goal of this paper is the determination of the temperature at the under-specified boundary (inner boundary of an annular do
