6. Redesign of a tribological pin-on-disc machine
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : In contradistinction with road transport exhaust particulate matter (PM) emission, non-exhaust PM emission has not decreased substantially in recent years. One source of non-exhaust PM emission is studded tyre-pavement contact. LÄS MER
7. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER
8. Driftoptimering av värme- och kylsystemet på Centralsjukhuset i Karlstad : Driftstrategier för perioden oktober - april
Magister-uppsats, Karlstads universitetSammanfattning : De förhöjda halterna av växthusgaser i luften leder till ett varmare klimat och extremväder blir vanligare,vilket är två viktiga aspekter till att minska klimatavtrycket. Region Värmland skapade 2021 en miljöplan för att minimera klimatavtrycket, använda resurserna på ett klimatsmart sätt samt bidra till en hälsosammare miljö. LÄS MER
9. Electron Backscatter Diffraction (EBSD) Analysis and Predicted Physical Properties of Shocked Quartz from the Chicxulub Impact Crater, Mexico
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : As one of the most common minerals in crustal rocks, quartz has been widely used as an indicator for shock metamorphism. Shocked quartz is found in the Chicxulub impact crater, an impact crater that has been linked to the Cretaceous-Tertiary extinction ~66 million years ago. LÄS MER
10. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. LÄS MER
