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...

  In this paper, we use modified Laplace decomposition method to solving initial value problems (IVP) of the second order ordinary differential equations. Theproposed method can be applied to linear and nonlinearproblems    

An atomic decomposition is considered in Banach space.  A method for constructing an atomic decomposition of Banach  space, starting with atomic decomposition of  subspaces  is presented. Some relations between them are established. The proposed method is used in the  study  of the  frame  properties of systems of eigenfunctions and associated functions of discontinuous differential operators.

In this paper we will give a short introduction to the installation and efficiency of state-of-the-art direct solver packages like CROUT and UMFPACK for linear systems, combined with highly processor optimised BLAS libraries. We will give an overview about the methods that can be used to integrate these libraries into Fortran programs compiled with the Compaq® Visual Fortran or the Intel® Fortr...

in this paper, the potential of polarimetric sar data using target decomposition features to detect oil pollutions are evaluated. for this purpose, the values of power, phase and magnitude of all of the polarization channels (hh, vv, hv and vh) and decomposition features i.e. freeman, yamaguchi, vanzyl and krogager are computed. then, to detect oil pollutions, different combinations of these fe...
