Abstract Background The optimal time to initiate renal replacement therapy (RRT) in intensive care unit (ICU) patients with acute kidney injury (AKI) is unclear. We examined the impact of early RRT on long-term mortality, risk of chronic kidney disea

Derivation and investigation of fifth order quadrature formulas for biharmonic boundary integral operators

Autor: Søren Christiansen

Publikováno v: Applied Numerical Mathematics. 37:145-159

Integral operators can conveniently be replaced by matrices through a quadrature followed by a collocation. For two operators related to biharmonic boundary integral equations we derive quadrature formulas with convergence order five . The fifth orde

Derivation and analytical investigation of three direct boundary integral equations for the fundamental biharmonic problem

Autor: Søren Christiansen

Publikováno v: Journal of Computational and Applied Mathematics. 91:231-247

We derive and investigate three families of direct boundary integral equations for the solution of the plane, fundamental biharmonic boundary value problem. These three families are fairly general so that they, as special cases, encompass various kno

A stability analysis of a Eulerian solution method for moving boundary problems in electrochemical machining

Autor: Søren Christiansen

Publikováno v: Journal of Computational and Applied Mathematics. 3:269-296

We investigate the front-tracking method using marker points for the numerical solution of a class of moving boundary problems, which arise in connection with certain two-dimensional electrochemical machining problems. The numerical method is express
