2. 16. Cost-effective fuel choices in the transportation sector under stringent CO2-emission reduction targets - Global energy systems modelling

   Author : Maria Grahn; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Global energy systems; carbon dioxide emissions; biomass; liquid biofuels; primary energy price; transportation sector; hydrogen; carbon tax; energy scenarios;

   Abstract : This thesis analyzes the worlds future energy supply in general, and cost-effective fuel choices in the transportation sector in particular, under stringent CO2 constraints. The analysis is carried out with the help of a global energy systems model (GET), developed and modified specifically for each project. READ MORE

4. 17. Mathematical Tools Applied in Computational Electromagnetics for a Biomedical Application and Antenna Analysis

   Author : Farid Monsefi; Sergei Silvestrov; Magnus Otterskog; Linus Carlsson; Jean-Pierre Bérenger; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Abstract : To ensure a high level of safety and reliability of electronic/electric systems EMC (electromagnetic compatibility) tests together with computational techniques are used. In this thesis, mathematical modeling and computational electromagnetics are applied to mainly two case studies. READ MORE

5. 18. Comparative Study of Teaching Computational Mathematics in Two Different Learning Environments

   Author : Dara Maghdid; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational mathematics; Teaching style; Variation Theory; Mathematics values; Motivation;

   Abstract : This thesis aims to investigate necessary adaptations in the design of a mathematics course when it is transferred from one cultural environment to another. We focus on an elementary course in computational mathematics with Python taught at Lund University, Sweden, and at Soran University, Kurdistan/Iraq. This project holds two main parts. READ MORE

6. 19. Models for capturing the penetration of a diffusant concentration into rubber : Numerical analysis and simulation

   Author : Surendra Nepal; Adrian Muntean; Nadja Ray; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transport of diffusants; moving-boundary problem; finite element method; a priori and a posteriori error estimates; random walk method; two-scale coupled system; Matematik; Mathematics;

   Abstract : Understanding the transport of diffusants into rubber plays an important role in forecasting the material's durability. In this regard, we study different models, conduct numerical analysis, and present simulation results that predict the evolution of the penetration front of diffusants. READ MORE
