    • An Immersed Interface Method for the Incompressible Navier-Stokes Equations 

      Le, Duc-Vinh; Khoo, Boo Cheong; Peraire, Jaime (2004-01)
      We present an immersed interface algorithm for the incompressible Navier Stokes equations. The interface is represented by cubic splines which are interpolated through a set of Lagrangian control points. The position of ...

    • An Algorithm for Computing the Symmetry Point of a Polytope 

      Belloni, Alexandre; Freund, Robert M. (2004-01)
      Given a closed convex set C and a point x in C, let sym(x,C) denote the symmetry value of x in C, which essentially measures how symmetric C is about the point x. Denote by sym(C) the largest value of sym(x,C) among all x ...

    • Aerodynamic Shape Design of Nozzles Using a Hybrid Optimization Method 

      Xing, X.Q.; Damodaran, Murali (2004-01)
      A hybrid design optimization method combining the stochastic method based on simultaneous perturbation stochastic approximation (SPSA) and the deterministic method of Broydon-Fletcher-Goldfarb-Shanno (BFGS) is developed ...
