The variance estimator of a sample tells you how much the data vary ....
but how much does that variance estimator vary around the true variance? This R-package
computation of exact confidence intervals of the variance estimator, without normality
assumption on the underlyingdistribution, tells you.

Inferential statistics of stress states in rigid body continuum
Series of four finite element calculations of a 2d rectangular element under
shear stress, subject to random perturbations in each iteration, with first and second
stress lines in blue and orange (deformations not to scale). In this project, we develop a
for statistical analysis of stress fluctuations as in this series. In each subfigure, the
the centre is associated with a particular two-by-two Cauchy stress tensor. A component-wise
averaging procedure, resulting in the two-by-two mean Cauchy stress is not an adequate
procedure because it disrespects the magnitudes of its eigenvalues, the principal stresses.
we propose a methodology for averaging and comparing large numbers of perturbed stress
circumventing this problem. We thereby allow the researcher to compute measures for the
certainty of difference in means between two sets of samples. An important application is
control of finite element simulations.

Rhino3d grasshopper plugin that designs membranes in real-time and computes
approximate solutions to the classical Poisson problem of PDE theory, using a complex
algorithm instead of a direct matrix method.
