    A Multifidelity Monte Carlo Method for Realistic Computational Budgets

    A method for the multifidelity Monte Carlo (MFMC) estimation of statistical quantities is proposed which is applicable to computational budgets of any size. Based on a sequence of optimization problems each wi...

    An Improved Discrete Least-Squares/Reduced-Basis Method for Parameterized Elliptic PDEs

    It is shown that the computational efficiency of the discrete least-squares (DLS) approximation of solutions of stochastic elliptic PDEs is improved by incorporating a reduced-basis method into the DLS framewo...

    Analysis of Nonlinear Spectral Eddy-Viscosity Models of Turbulence

    Fluid turbulence is commonly modeled by the Navier-Stokes equations with a large Reynolds number. However, direct numerical simulations are not possible in practice, so that turbulence modeling is introduced. ...
