Finally, the better compromise between the error on volume conservation and the shape of the solution is probably to use the high-order Weighted Essentially Non-Oscillatory

Here, we apply the same idea in the quantum setting in order to derive the first order correction to the isothermal Euler equation of [5].. By analogy, we shall call

Numerical tools must be developed to deal with the normal velocity jump condition, to determine accurately the thermal field close to the interface and to deduce the boiling mass

In the case of Hopf bifurcation, for each Reynolds number, we compute an indicator versus the angular frequency curve, written G Re (µ, ω).. We know for this example that the

We obtain a faster version of spectral clustering while preserving the properties of spectral clustering, referred to as power spectral clus- tering or Power Ratio cut or more
