Imaging of atmospheric dispersion processes with Differential Absorption Lidar

Robert Lung, Nick Polydorides

We consider the inverse problem of fitting atmospheric dispersion parameters based on time-resolved back-scattered differential absorption Lidar (DIAL) measurements. The obvious ad…

Application of Randomized Quadrature Formulas to the Finite Element Method for Elliptic Equations

Raphael Kruse, Nick Polydorides, Yue Wu

The implementation of the finite element method for linear elliptic equations requires to assemble the stiffness matrix and the load vector. In general, the entries of this matrix-…

A Multilevel Monte Carlo Estimator for Matrix Multiplication

Yue Wu, Nick Polydorides

Inspired by the latest developments in multilevel Monte Carlo (MLMC) methods and randomised sketching for linear algebra problems we propose a MLMC estimator for real-time processi…
