    Software development in Urdu has been going on for more than three decades. However, until recently there were no industry standards for coding in Urdu, similar to ASCII standard for English. Keeping in view the necessity and urgency of standardization needs, three years ago a national effort was initiated to get relevant people together and formulate a common standard for everybody to follow.

    We consider the penalty method approach, and corresponding numerical schemes, for solving the Black-Scholes model of the American Option. Standard methods involve the need to solve a system of nonlinear equations, evolving from the finite difference discretization of the nonlinear Black-Scholes model, at each time step by a Newton-type iterative procedure. We analyze the well-known linearly implic... View full abstract»

    Fields scattered by a sphere near a Hertz dipole are derived using a rigorous analytical method with the Mie scattering approach. However, the incident field on the sphere has not been considered a plane wave, rather these are the fields radiated from the Hertz dipole. A general solution of the fields scattered by the sphere has been sought, when the sphere is present in the near and far field of ... View full abstract»

    An implicitly restarted Krylov subspace model reduction method is presented. By this technique a stable, linear transfer function f(s) of order n can be approximated by an order m, where n≫m. The oblique projection of stable systems onto a Krylov subspace may generate unstable partial realizations along with undesirable modes. To ensure that the Krylov projected model for a stable system is als... View full abstract»
