    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 ...

    Numerical Methods for Computing Nonlinear Eigenpairs: Part II. Non-Iso-Homogeneous Cases
    Download  www.math.tamu.edu
    Standing (solitary)-wave/steady-state solutions in many nonlinear wave motions and Schrodinger flows lead to nonlinear eigenproblems. In [X. Yao and J. Zhou, SIAM J. Sci. Comput., ...

    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...
