1. Sprickorna i Konstnärsförbundets styrelse
Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvårdSammanfattning : All oil paintings do degrade with time and a clear sign of this ageing is the cracks seen at the surface of the painting. Cracks can , however, also be hidden underneath the very surface and in fact extend all the way down to the very substrate. LÄS MER
2. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. LÄS MER
3. Optimisation of tribology of Alfa Laval separator screw gear systems
Master-uppsats, Luleå tekniska universitet/MaskinelementSammanfattning : Gears are machine elements essential for mechanical transmission. Wear of gear teeth can causechanges in their profile geometry, causing vibration, noise, and subsequent gear failure. In this thesisproject, a twin disc tribometer has been used to mimic the actual Alfa Laval separator screw gearsystems. LÄS MER
4. The Influence of Electric Currents on Performance of Grease Lubricated Rolling Element Bearings
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : The technological advancement in electrical machinery represents the need to understand the lubricant behaviour in the electrical environment. As shaft voltages are unavoidable in electrical machinery, developing new grease formulations and studying their performance against electric loads is required. LÄS MER
5. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it. LÄS MER
