    Accurate Floating-Point Summation Part I: Faithful Rounding
    Download  www.ti3.tu-harburg.de
    Given a vector of floating-point numbers with exact sum s, we present an algorithm for calculating a faithful rounding of s, i.e. the result is one of the immediate floating-point ...

    Splitting Methods Based on Algebraic Factorization for Fluid-Structure Interaction
    Download  infoscience.epfl.ch
    We discuss in this paper the numerical approximation of fluid-structure interaction (FSI) problems dealing with strong added-mass effect. We propose new semi-implicit algorithms ba...
