This paper compares the variational iteration method (VIM), the Adomian decomposition method (ADM) and the Picard iteration method (PIM) for solving a system of first order nonlinear ordinary differential equations (ODEs). A unification of the concepts underlying these three methods is attempted by considering a very general iterative algorithm for VIM. It is found that all the three methods can be regarded as special cases of using a very general matrix of Lagrange multipliers in the iterative algorithm of VIM.

We are looking for two postdoctoral researchers to work on the following topics at Nanyang Technological University, Singapore.  

1. Modeling the welding process using finite element method.  

2. First-principles calculations of novel nanomaterials for energy harvesting applications.  

I have been looking at XFEM literature for a while and wondering why do we need 2 different heaviside enrichment functions in XFEM? In paper titled "A finite element method for crack growth without remeshing" by Nicolas Moes et al.(1999), they use the following function for heaviside enrichment:

 H(x,y)={1, for y>0

             -1,for y<0}

We are looking for candidates for doctoral positions in the areas of computational and experimental biomechanics. Candidates must have earned a M.Sc. degree in Mechanical Engineering or in a related field from an accredited University. Candidates with strong background in numerical simulations (e.g. C++ and FORTRAN programming skills, finite element analysis, and high performance computing) and/or previous experience in experimental characterization of bioogical tissues are highly desirable.
