  1. 1. Analysis on copper, lead and tin removal in steel scrap sorting : Technologies involved, environmental considerations and economic aspects

    Master-uppsats, KTH/Materialvetenskap

    Författare :Giada Cavaliere; [2023]
    Nyckelord :Copper; Tin; Lead; Steel Scrap Sorting; Ballistic Separation; Dilution; Revenue Modelling; CO2 emissions Modelling; Tenn; Bly; Sortering av stålskrot; Ballistisk separation; Utspädning; lntäktsmodellering; CO2-utsläppsmodellering;

    Sammanfattning : With the urgency of cutting down CO2 emissions to reach climate neutrality by 2050, decarbonization of the steel industry is on the European Commission's agenda. Steelmaking accounts for 10 % of anthropogenic CO2 emissions and it is one of the most challenging sectors to decarbonize. LÄS MER

  3. 2. Profinite groups

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Juan Moreno Poncela; [2023]
    Nyckelord :Profinite Groups; Infinite Galois Theory; Mathematics and Statistics;

    Sammanfattning : This thesis provides a comprehensive study of profinite groups, which are fascinating mathematical objects that have attracted significant interest in modern algebraic research. Profinite groups are infinite generalizations of finite groups and share many similarities with them. LÄS MER

  4. 3. Parametrisk modellering av pålgrupper: Koppling mellan Grasshopper och Sofistik

    M1-uppsats, KTH/Byggteknik och design

    Författare :Kimm Nordvall; Mikael Stenberg; [2022]
    Nyckelord :FEM; Finite elements; Parametric modelling; Sofistik; Grasshopper; Rhinoceros; Piling; FEM; Finita element; Parametrisk modellering; Sofistik; Grasshopper; Rhinoceros; Pålgrundläggning;

    Sammanfattning : Pålgrundläggning är en vanlig metod vid grundläggning där sämre markförhållanden råder. För broaroch andra anläggningskonstruktioner måste stora laster tas i beaktande, både horisontella ochvertikala. LÄS MER

  5. 4. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Omar Orgeira Alvarez; [2022]
    Nyckelord :Base station; Mobile communications; Phased arrays; Vivaldi antenna; Stripline; Basstation; Mobilkommunikation; Phased arrays; Vivaldi-antenn; Stripline;

    Sammanfattning : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. LÄS MER

  7. 5. Changes in Gray cast iron over the last century-An initial study

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Puneeth Kumar Shivarudrappa; [2021]
    Nyckelord :Gray cast iron; age strengthening; and machinability.; Technology and Engineering;

    Sammanfattning : This thesis report summarizes the research on the cold aging of gray cast iron samples dating back 100 years, and how researchers looked at the phase history and amount of impurities and trace metals generated by recycling. Initially, the topic of the thesis is introduced, with an explanation and general information on gray cast iron. LÄS MER
