  1. 11. Magnetic Moment Characterization for Small Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Alejandro Sans Monguiló; [2021]
    Nyckelord :small satellite; CubeSat; optical magnetic test bed; magnetic dipole moment characterization; residual magnetic moment; permanent magnet verification; magnetic measurement; Foresail-1; Helmholtz cage;

    Sammanfattning : Small satellites are gaining popularity in a wide range of applications where attitude systems require high precision performance. One of the main sources of errors, in case of magnetic attitude control systems, is the residual magnetic moment (RMM) of the spacecraft. LÄS MER

  3. 12. Alkaline wet oxidation of biorefinery lignin from wheat straw

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maja Lindblad; [2021]
    Nyckelord :alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Sammanfattning : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. LÄS MER

  4. 13. Implementering av fjärde generationens fjärrvärme i svenska fjärrvärmenät : En fallstudie på Borlänges fjärrvärmenät

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Henrik Nordström; Klara Smeds; [2021]
    Nyckelord :4GDH low temperature district heating; 4GDH lågtempererad fjärrvärme;

    Sammanfattning : För att möta problem med ökande klimatförändringar kan fjärrvärmen ha en betydande roll ur både en svensk och en internationell kontext. Samtidigt står svenska fjärrvärmebolag inför betydande utmaningar då värmepumpar blir ett allt vanligare val för att möta uppvärmnings- och tappvarmvattenbehovet, tillgången till avfall och biomassa som bränsle förutspås bli mer begränsad och byggnaders uppvärmningsbehov blir allt lägre.

  5. 14. Polygeneration system model in rural areas of Colombia : Filipinas ETCR as a case of study

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Nestor Ruiz Crespo; [2021]
    Nyckelord :;

    Sammanfattning : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.

  7. 15. Investigation of Cu and Zn interactions with ilmenite during waste incineration

    H-uppsats,

    Författare :Elin Borgman; [2020-06-08]
    Nyckelord :FactSage; copper; zinc; major ash elements;

    Sammanfattning : In 2018, approximately 2.01 billion tons of waste was generated in the world. By 2050, this number is expected to increase drastically to 3.40 billion tons of waste annually as lower income countries develop and the world population increases (Kaz, Yao, BhadaTata, & Van-Woerden, 2018).
