The Hardy inequality and the heat equation in twisted tubes
We show that a twist of a three-dimensional tube of uniform cross-section yields an improved decay rate for the heat semigroup associated with the Dirichlet Laplacian in the tube. The proof employs Hardy inequalities for the Dirichl...

Hardy Inequalities in Globally Twisted Waveguides
We establish various Hardy-type inequalities for the Dirichlet Laplacian in perturbed periodically twisted tubes of non-circular cross-sections. We also state conjectures about the existence of such inequalities in more general regi...

Two Iterative Methods for Sizing Pipe Diameters in Gas Distribution Networks with Loops
. They are based on the following: (1) a modified Hardy Cross method with the correction of the diameter in each iteration and (2) the node-loop method, which provides a new diameter. The presented optimisation is ...
