  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. Miljömässiga besparingar i lagerverksamheter : Framtagning av en modell för besparandet av koldioxidekvivalenter i kunders lagerverksamhet för Consafe Logistics

    Master-uppsats, Linköpings universitet/Logistik- och kvalitetsutveckling

    Författare :Lukas Söderholm; Axel Telenius; [2023]
    Nyckelord :Modelling; emissions; warehousing; reduction; CO2e; forklift; customer segment; sustainability;

    Sammanfattning : Companies are having to adhere to higher demands regarding their environmental emissions, this also stands true for the companies warehousing. In warehouses, both picking and moving goods is done using forklifts which leads to energy use and thereby environmental emissions for these activities. LÄS MER

  4. 3. Dynamic Covariance Modelling Using Generalised Wishart Processes

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Fredrik Nilsson; [2023]
    Nyckelord :Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

    Sammanfattning : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. LÄS MER

  5. 4. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Eddie Blomström; [2022]
    Nyckelord :fishway; flow; hydraulics; HEC-RAS;

    Sammanfattning : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. LÄS MER

  7. 5. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Lassi Linnala; [2022]
    Nyckelord :femtosecond THz radiation; ultrafast x-ray diffraction; pump-probe; longitudinal optical phonons; zincblende semiconductors; anharmonic decay; density functional perturbation theory; Physics and Astronomy;

    Sammanfattning : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.
