1. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems
Kandidat-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskapSammanfattning : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. LÄS MER
2. Orientation of plasma jet fronts in the Earth's magnetotail
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : This project aims to investigate the orientation of plasma jet fronts in Earth's magnetotail using multi-spacecraft measurement data. The orientations are estimated by applying minimum variance analysis (MVA) and multi-spacecraft timing analysis for finding normal vectors to the jet fronts as they pass over the spacecraft. LÄS MER
3. Expressibility of multiscale physics in deep networks
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Motivated by the successes in the field of deep learning, the scientific community has been increasingly interested in neural networks that are able to reason about physics. As neural networks are universal approximators, they could in theory learn representations that are more efficient than traditional methods whenever improvements are theoretically possible. LÄS MER
4. Digital Twins in Industrial Product Realization - A Literature Study
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Increased focus on sustainability in conjunction with larger demand for individualized and customized products are presenting the manufacturing industry with new challenges in production cycle management and sustainable processes. Digital Twin Technology is an emerging technology and could be an answer to these challenges. LÄS MER
5. Heterogena Multiskalmetoder för Högt Oscillativa och Dissipativa Ordinära Differentialekvationer
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : I den här uppsatsen studerar vi en klass av numeriska algoritmer som går under namnet heterogena multiskalmetoder. Vi presenterar en introduktion till ämnet och analyserar stabiliteten och noggranheten för några implementationer på dissipativa och oscillativa problem. LÄS MER
