Ahmad, Fayyaz; Bhutta, Toseef Akhter ; Sohaib, Umar; Ullah, Malik Zaka; Alshomrani, Ali Saleh; Ahmad, Shamshad; Ahmad, Shahid (2017-01-18)
Article
Accés obertA modification to an existing iterative method for computing zeros with unknown multiplicities of nonlinear equations or a system of nonlinear equations is presented. We introduce preconditioners to nonlinear equations or ... -
An efficient method for the static deflection analysis of an infinite beam on a nonlinear elastic foundation of one-way spring model
Ahmad, Fayyaz; Ullah, Malik Zaka; Jang, Taek Soo; Alaidarous, Eman (2017-10-03)
Article
Accés obertAn efficient numerical iterative method is constructed for the static deflection of an infinite beam on a nonlinear elastic foundation. The proposed iterative scheme consists of quasilinear method (QLM) and Green’s function ... -
Constructing frozen Jacobian iterative methods for solving systems of nonlinear equations, associated with ODEs and PDEs using the homotopy
Qasim, Uswah; Ali, Zulifgar; Ahmad, Fayyaz; Serra Capizzano, Stefano; Ullah, Malik Zaka; Asma, Mir (2016-03-01)
Article
Accés obertA homotopy method is presented for the construction of frozen Jacobian iterative methods. The frozen Jacobian iterative methods are attractive because the inversion of the Jacobian is performed in terms of LUfactorization ... -
