1406.4254 | we present gpu implementations of two fast force calculation methods , based on series expansions of the poisson equation . one is the self - consistent field ( scf ) method , which is a fourier - like expansion of the density field in some basis set ; the other is the multipole expansion ( mex ) method , which is a ta... | 231 |
1212.3456 | let @xmath0 be a finite set of circles in the plane . we point out that the usual convex closure restricted to @xmath0 yields a convex geometry , that is , a combinatorial structure introduced by p.h . edelman in 1980 under the name `` anti - exchange closure system '' . we prove that if the circles are collinear and t... | 137 |
1511.00098 | matching cross - view images is challenging because the appearance and viewpoints are significantly different . while low - level features based on gradient orientations or filter responses can drastically vary with such changes in viewpoint , semantic information of images however shows an invariant characteristic in ... | 215 |
