1. Flow Over Large-Scale Naturally Rough Surfaces
Sammanfattning : The fluid mechanical field of rough surface flows has been developed ever since the first experiments by Haagen (1854) and Darcy (1857). Although old, the area still holds merit and a surprising amount of information have to this day yet to be fully understood, which surely is a proof of its complexity. LÄS MER
2. Translating grand challenges into municipal organizing : Prevention of terrorism, extremism, and radicalization in Scandinavia
Sammanfattning : This thesis investigates why and how municipalities organize to address grand challenges. Previous research shows that municipalities have increased their policymaking and organizing in relation to grand challenges, often without any national regulations forcing them to do so. LÄS MER
3. Decoding the Structural Layer of Transcriptional Regulation : Computational Analyses of Chromatin and Chromosomal Aberrations
Sammanfattning : Gene activity is regulated at two separate layers. Through structural and chemical properties of DNA – the primary layer of encoding – local signatures may enable, or disable, the binding of proteins or complexes of them with regulatory potential to the DNA. LÄS MER

5. Squat defects and rolling contact fatigue clusters - Numerical investigations of rail and wheel deterioration mechanisms
Sammanfattning : Squat defects, a type of localised rolling contact fatigue damage appearing on rail surfaces with rail break as an ultimate consequence, have concerned infrastructure managers for the last couple of decades. In recent years similar types of defects—so-called studs—that are visually resembling squats, have started to appear. LÄS MER
