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…
Generative Adversarial Network (GAN) based Image-Deblurring
Yuhong Lu, Nicholas Polydorides
This thesis analyzes the challenging problem of Image Deblurring based on classical theorems and state-of-art methods proposed in recent years. By spectral analysis we mathematical…
Learned Spectral Computed Tomography
Dimitris Kamilis, Mario Blatter, Nick Polydorides
Spectral Photon-Counting Computed Tomography (SPCCT) is a promising technology that has shown a number of advantages over conventional X-ray Computed Tomography (CT) in the form of…
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 Sketched Finite Element Method for Elliptic Models
Robert Lung, Yue Wu, Dimitris Kamilis +1
We consider a sketched implementation of the finite element method for elliptic partial differential equations on high-dimensional models. Motivated by applications in real-time si…
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…
