Subdivision Surface

SPM surfrend toolbox is a suite of scripts that add surface-based rendering capabilities to SPM99/2 generated statistical maps.

Venn diagrams are an interesting method for rendering triadic relations on a two dimensional drawing surface. Certain marks (or annotations) indicate the existence of variables or constants in the distinguishable regions.

VISTAS (VCSEL Integrated Spatio-Temporal Advanced Simulator) is a highly efficient 2D, time-domain Vertical-Cavity Surface-Emitting Laser (VCSEL) model aimed at optimizing entire optical links.

Based on Ken Elder's 1993 paper: "Langevin simulations of nonequilibrium phenomena" Computers In Physics, vol. 7, no. 1, 1993, p.27-33.Domains of ordered phase are created from an initially disordered phase due to thermal fluctuations. The domains coarsen as a function of time. Large domains grow...

The Mogi [1958] model allows to calculate analytic solution for surface deformation due to a point source in an elastic half-space. This model is widely used to simulate ground deformation produced by local perturbation like volcanic magma chamber. It computes displacements, tilt and strain in a...

This program represents a further development of the standard powerful d-deDUnlinfitd-deDt facility already in matlab. The major problem with d-deDUnlinfitd-deDt is that it can only handle fitting of one dimensional arrays (x, y) where x is the independent variable and y is the dependent one.The...
