Nobuyuki Satofuka,Koji Morinishintribute to prosthesis stability in a semi-constrained ankle prosthesis. There is evidence that, in a mobile-bearing ankle, abnormal talar motion within the ankle mortise, especially in the coronal plane, may cause polyethylene wear, whereas, in a fixed-bearing ankle, axial malrotation may cause asymmetric polyethylene wear.

The Computation of Steady Solutions to the Euler Equations: A Perspectiveomputational grid, numerical noise and even instabilities may arise, leading to losses of accuracy and efficiency. Finding the location of those layers is a problem of pattern recognition, the solution of which requires a fair share of the computational budget.

Book 1989ncy several codes for solving compressible inviscid, mainly steady, Euler flows. This workshop was a sequel of the GAMM workshop held in 1979 in Stockholm; this time, though, because of the present strong activity in numerical methods for the Euler equat.ions, the full-potential approach was not inc

A Finite Element Scheme for the Euler Equationsthe elements can be stretched in the direction of any one-dimensional features and their size may vary significantly through the region of interest. This leads to meshes in which the number of nodes does not increase dramatically at each step of the adaptive procedure.

Implicit Finite-Volume Algorithms for the Flux-Split Euler Equationsms in conjunction with FAS multigrid acceleration to steady-state. Several internal/external steady flows over cascades/airfoils are computed, as well as the time-accurate flow over a circular cylinder at supercritical conditions.

Computation of Transonic Steady Flows Using a Modified Lambda Formulation per integration step. Such an approach belongs to the upwind differencing methods, which take into account the waves propagation directions and accordingly approximate the space derivatives with appropriate upwind differences, so that the domains of dependence are correctly respected by the numerical technique.
