Interactive shape preserving interpolation by curvature continuous rational cubic splines
(Lincoln University. Applied Computing, Mathematics and Statistics Group, 1999-01)
A scheme is described for interactively modifying the shape of convexity preserving planar interpolating curves. An initial curve is obtained by patching together rational cubic and straight line segments. This scheme has, ...
Effects of different dispersal patterns on the presence-absence of multiple species
Predicting which species will be present (or absent) across a geographical region remains one of the key problems in ecology. Numerous studies have suggested several ecological factors that can determine species presence-absence: ...
