  1. 1. Reprocessing weather data from Smart Stake weather stations on the Greenland ice sheet

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Leon Lovén; [2023]
    Keywords : ice sheet; data processing; weather station; Greenland; GEUS; Smart Stake; istäcke; databehandling; väderstation; Grönland; GEUS;

    Abstract : To identify a climate trend, a lot of data is required for the conclusion to be accurate. A trend can require 30 years worth of measurements in order to say anything with certainty about how the climate is changing. It is therefore important to utilize every source of data in climate research. READ MORE

  3. 2. Projection Nut Welding to High- and Ultra-high Strength Steels

    University essay from KTH/Hållfasthetslära

    Author : Love Englund; [2023]
    Keywords : mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Abstract : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. READ MORE

  4. 3. EU ETS Fourth Phase Firm-Level Effects : An Exploratory Study of Implications for Swedish Industry within the EU ETS

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : JOAR HARALDSSON; LINUS LOGREN; [2022]

    Abstract : The European Union Emission Trading System (EU ETS) is the cornerstone of the EU's transition to climate neutrality by 2050. Significant carbon price increases and ambitious changes to the ETS make phase four (2021-2030) uncharted territory. READ MORE

  5. 4. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  6. 5. Petrography and Mineral Chemistry of the Sälskär Breccia (Alnö Alkaline Complex, Central Sweden)

    University essay from Uppsala universitet/Institutionen för geovetenskaper
