1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction
Master-uppsats, KTH/MaterialvetenskapSammanfattning : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and the content of non-metallic inclusions (NMI). Achieving cleanliness is a gradual process where all the steps of the production process are inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

2. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.
Master-uppsats, Karlstads universitetSammanfattning : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. LÄS MER
3. Micromechanical Characterization of Thin Paper Materials
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska HögskolaSammanfattning : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. LÄS MER
4. Local Nature Matters : A Story of How Empowerment from Tourism Contributes to Local Nature Stewardship in Rural Communities
Master-uppsats, Linnéuniversitetet/Institutionen för marknadsföring och turismvetenskap (MTS)Sammanfattning : This Master thesis examines the role of resident empowerment in rural nature tourism in shaping the relations between how residents engage with local places and local nature stewardship in Plouguerneau, France. Through a conceptual framework that includes the concepts of empowerment, place attachment, care for nature, and nature stewardship, the study models the effect of place attachment and care for nature on resident stewardship attitudes and how resident empowerment in tourism mediates this relationship.

5. Design and implementation of an energy harvesting system in a prosthetic limb
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER
