TL;DR

This article analyzes the parallel scalability of the WILDFIRES-IGA-ADS simulator on a concurrent server with shared memory and employs the isogeometric finite element method with tensor product B-spline basis functions, explicit time integration schemes, and a linear computational cost solver resulting from the Kronecker product structure of the mass matrix.

The optimal-transport cartogram: world population as a Brenier map

A contiguous cartogram is a map whose area is proportional to a quantity such as population. The defining condition, that the Jacobian determinant of the deformation equals the density, is one equation for two unknown functions, so every cartogram method adds a tie-breaker, usually implicitly. Optimal transport makes t...
