  1. 11. Modelling and Techno-economic Analysis of a Hybrid CSP/PV System using Solid Oxide Electrolyser for Hydrogen Production

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

    Författare :Chuanyin Tang; [2023]
    Nyckelord :Power to Hydrogen; Solid Oxide Electrolyser; CSP; PV; LCOE; LCOH.;

    Sammanfattning : This project proposes a solar-driven hybrid system for electricity generation and hydrogen production, which includes concentrated solar power (CSP), photovoltaic (PV), solid oxide electrolyser (SOEC). Electricity from the CSP and PV provides a continuous 24/7 supply to meet demand-side power consumption.

  3. 12. Dynamisk analys av betonghåldäck : Parametrisk FEM studie

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Angelica Drakneid; Jasmine Weber; [2023]
    Nyckelord :;

    Sammanfattning : Hollow-core concrete slabs can be used in buildings to achieve longer floor spans in comparison to regular concrete slabs. However, longer floor spans in combination with low dead-weight make them more susceptible to vibrations.Frequencies between 0-15 Hz are relevant to study since these lower frequencies affect the comfort of humans.

  4. 13. Hur gammal är jordens inre kärna?

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tim Bergström; [2023]
    Nyckelord :Inner core; thermal conductivity; convection; Earth’s magnetic field; paleomagnetism; Earth and Environmental Sciences;

    Sammanfattning : Åldern för jordens inre kärna är en gåta som har förbryllat forskare i många decennier. Allt från en ålder lika hög som jordens magnetfält (mellan 3,5 och 4,2 Ga) i den ena änden, ner till 0,5 Ga i den andra änden. LÄS MER
