1. Strukturella förbättringar av en markstabiliseringsmast
Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknikSammanfattning : This report has examined the possibilities of stiffening and strengthening a ground stabilization mast, in a way that a small production company can manufacture. The soil stabilization technique in question is Jet-Grouting also called injection drilling, which involves drilling to the desired depth and then letting high-pressure water jets mixed with filling mass to erode the surrounding soil mass and form pillars below the ground surface.

2. Dielectrics calculation of on-load tap-changer VUCL
M1-uppsats, KTH/Hållbar produktionsutveckling (ML)Sammanfattning : This is a bachelor's thesis in Mechanical engineering. The main topic of the thesis is the electrical calculation of the tap changer's shield. Although there are many kinds of tap-changers, this study focuses on VUCL models. The theoretical background of the thesis is that the new shield is suitable and useable in all VUCL models. LÄS MER
3. Improved methodology for postulated fuel handling accident
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/HållfasthetsläraSammanfattning : This report presents a suggestion of an improved method for evaluation of a fuel handling accidents. Using a 3D FE-model and ANSYS LS-DYNA EXT the structural analysis is carried out. Importing geometry from SpaceClaim and simplifying it creates the geometry used in this analysis. LÄS MER
4. CFD Simulations of Flow Characteristics of a Piano Key Weir Spillway
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : Comprehensive rehabilitation projects of dam spillways are made in Sweden, due to stricter dam safety guidelines for their discharge capacity. The Piano Key Weir (PKW) is an innovative design which has proven effective through several renovation projects made in many countries including France. LÄS MER
5. Aeration and risk mitigation for flood discharge tunnel in Zipingpu water conservancy project
Master-uppsats, KTH/BetongbyggnadSammanfattning : The importance of hydraulic structures has become an essential mitigating mean for floodsthat occur more often due to climate change. Thus, the importance and safety of flooddischarge tunnels has promoted further studies and experiments on the topic to mitigatedamages, such as cavitation that arise because of high speed flows.
