Computing weak distance between the 2-sphere and its nonsmooth approximations
Kazuki Koga
A novel algorithm is proposed for quantitative comparisons between compact surfaces embedded in the three-dimensional Euclidian space. The key idea is to identify those objects wit…

Signal processing approach to mesh refinement in simulations of axisymmetric droplet dynamics
Kazuki Koga
We propose a novel mesh refinement scheme based on signal processing for boundary integral simulations of inviscid droplet dynamics with axial symmetry. A key idea is to directly a…
