DOI: 10.1002/ppp.1909
Abstract: A numerical model is presented to test whether a hillslope diffusion approach can simulate the topographic evolution of some recently developed high-centred ice-wedge polygons south of Prudhoe Bay, Alaska. The polygons are adjacent to a… read more here.

From a Random Polygon in $$\mathbb {R}^m$$Rm to an Ellipse: A Fourier Analysis of Iterated Circular Convolutions
Sign Up to like & getrecommendations! Published in 2017 at "International Journal of Applied and Computational Mathematics"
DOI: 10.1007/s40819-017-0320-x
Abstract: We consider random, skew, N-gons in $$\mathbb {R}^m$$Rm, having zero centroids. We investigate a normalized, midpoint averaging transformation, repeatedly applied to the original polygon, which we identify with a normalized circular convolution modulo N. The… read more here.

DOI: 10.1080/13658816.2024.2391982
Abstract: Abstract Polygon characteristics, including area, shape, and topology, may be lost during rasterization, leading to inaccurate analyses. Maintaining multiple characteristics remains a challenging multi-objective optimization problem. This study introduces improved strategies for flexibly maintaining multiple… read more here.
