1. Tunnelbyggande vid partiell bergtäckning : En fallstudie av Nacka Centrums tunnelbanestation
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : I samband med urbanisering av städer ökar omfattningen av byggda delar och antalet pågående byggnadsprojekt. Den ökade bebyggelsen i kombination med samhällets intresse leder till att projekt utförs med minskad möjlighet att välja lämplig plats. LÄS MER
2. Catenary action to prevent progressive collapse in multistorey timber buildings : An experimental study of tube joints
Master-uppsats, Luleå tekniska universitet/Träteknik; Luleå tekniska universitet/Institutionen för tillämpad fysik, maskin- och materialteknikSammanfattning : In the modern building industry wood as a building material has been looked on as one of the solutions to lower the environmentally impact of the building industry. Building types that normally have been reserved for concrete and steel are today being built with wood as main load bearing component. LÄS MER
3. I skuggan av flaskan : En intersektionell analys av anhörigas påverkan
M1-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)Sammanfattning : Alcohol misuse has been an increasingly bigger problem and is considered a societal problem. Theoverarching purpose of this study is to illustrate the vulnerability of different groups such aschildren, adolescents and adults, in regards to being a relative to individuals suffering fromalcohol misuse.

4. Optimization of support in rock pillars between two parallel tunnels
Master-uppsats, KTH/Jord- och bergmekanikSammanfattning : When two parallel tunnels are excavated under high to moderate horizontal in-situ stresses combined with minor deformations in the pillar between the tunnels, the in-situ stresses can be redistributed over the tunnels in form of two compressive arches and are transferred from the roof to the abutments of the two tunnels. At additional deformations in the pillar, a new redistribution of the stresses can occur creating one compressive arch over both of the tunnels. LÄS MER
5. Predicting Top-Oil-Temperature in Power Transformers with Light Gradient Boosting Machine
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Online monitoring of mineral-oil-immersed transformer variables provide capabilities such as failure avoidance, optimization of load capacity and maintenance as well as extending the remaining life expectancy. A central role is played by the Top-Oil-Temperature which in its own is an indicator of harmful events or transformer states. LÄS MER
