1. Förutsättningar för hantering av länshållningsvatten från tunnelproduktion i byggandet av Ostlänken : Återanvändning av näringsämnen genom bevattning
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : When a tunnel is built in rock, a type of water is formed as a residual product. This tunnel wateris formed due to construction processes such as drilling requiring water and groundwater thatinfiltrates into the tunnel. The water can cause environmental damage if it is released directlyinto nature and needs to be treated. LÄS MER
2. Improving Water Droplet Prediction for Vehicle Exterior Water Management: Insights from Experimental and Simulation Studies
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : This thesis focuses on the study of water transportation on vehicle surfaces, which is crucial for ensuring the unobstructed operation of sensors and cameras in autonomous vehicles. The research aims to develop and validate experimental and simulation methods to enhance the understanding of water droplet behaviour and to create accurate models for computational fluid dynamics (CFD) simulations.

3. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. LÄS MER
4. Utvärdering av metod för beräkning av teoretiska sprickvidder för bestämning av tätningsresultat
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : When constructing a tunnel, the main challenges are geotechnical and hydrogeological. In the working process the aim in tunneling is to secure the rock mass by sealing the mass before blasting. This is done by grouting. LÄS MER
5. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. LÄS MER
