Choosing norms in adaptive FSI calculations

Two-level Adaptive Mesh Movement Algorithms for Fsi-computations

In this paper, we discuss procedures for computing the mesh movement in staggered FSI-simulations. The mesh movement is divided into a global and a local level. The global level is based on the solution of an incremental linear-elastic solid model using the structure movement as Dirichlet boundary conditions, and error estimates to guide the node relocation in the interior of the uid domain. Th...

Wavelets Approach in Choosing Adaptive Regularization Parameter

In noise removal by the approach of regularization, the regularization parameter is global. Constructing the variational model min g ‖f − g‖L2(R) + αR(g),g is in some wavelets space. Through the wavelets pyramidal decompose and the different time-frequency properties between noise and signal, the regularization parameter is adaptively chosen, the different parameter is chosen in different level...

Choosing integration points for QCD calculations by numerical integration

I discuss how to sample the space of parton momenta in order to best perform the numerical integrations that lead to a calculation of three jet cross sections and similar observables in electron-positron annihilation. Typeset using REVTEX

Pitfalls of choosing an order parameter for rare event calculations.

The mechanism of rare events in complex systems can be found by sampling dynamical paths that connect stable states. To calculate a rate using transition paths, an order parameter is required to describe the progress of the reaction and to distinguish the initial and final states. In this work, we compare two implementations of transition path sampling for Langevin paths, one for which paths ar...
