Rates of Asymptotic Regularity for Halpern Iterations of Nonexpansive Mappings
: In this paper we obtain new effective results on the Halpern iterations of nonexpansive mappings using methods from mathematical logic or, more specifically, proof-theoretic te...

Compression of dense and regular point clouds
We present a simple technique for single-rate compression of point clouds sampled from a surface, based on a spanning tree of the points. Unlike previous methods, we predict futur...
