11. Analysis of degradation of melamine and polyurethane paint systems using different characterization methods. An investigation of automotive paints on trucks
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Sammanfattning på svenska: Billacker är exponerade för solljus och nederbörd under hela lackens livslängd. Lacker behöver motstå faktorer i omgivningen som påverkar nedbrytningen för att leva upp till högt ställda visuella krav. LÄS MER
12. Hur kan en gammal industribyggnad med kulturhistoriskt värde göras om till bostäder? : En fallstudie av lokstallarna i Bollnäs
Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : In Sweden there is a shortage of housing whilst old, abandoned industrial buildingstake up space on desirable land. These buildings generally do not live up to today’s standards regarding comfort and energy efficiency and are therefore not used today. LÄS MER
13. Moment-resisting connections for glulam using birch plywood : An experimental study on both mechanical and adhesive connections
Master-uppsats, KTH/ByggnadsmaterialSammanfattning : The aim of this study was to investigate the load-bearing capacity and stiffness of mechanical and adhesively bonded connections in timber structures with gusset plates made of birch plywood, as a preliminary study for potential future use in long-span timber structures which could reduce the environmental impact of the building sector by substituting steel with wood products in moment-resisting connections. Birch plywood was chosen for this study due to its high bending strength in comparison to plywood made of softwoods and its availability on the market. LÄS MER
14. Additive manufacturing for replacement parts for Volvo cars equipment
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : During this master thesis project, various polymer materials have been studied in relation to additive manufacturing. Additive manufacturing is a 3D printing process that has facilitated the productivity of the company, Volvo Cars. The printing process is based on a design conceived from CAD software. LÄS MER
15. Glued connection for TCC slabs : Experimental and Numerical investigation
Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)Sammanfattning : Timber-concrete composite (TCC) structures are becoming more popular in several industrial applications as an efficient method for optimizing the structural performance and the cost of construction as well as lowering the emissions of carbon dioxide. TCC floors are more sustainable than pure concrete floors and more resistant to vibrations and excessive deflections than pure wooden floors. LÄS MER
