  1. 11. Hydrogen Fuel Cell Lifetime Simulation in Marine Applications

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Yifeng Zhong; [2022]
    Nyckelord :maritime transportation; FEMFC; lifetime simulation; degradation mechanism; empirical relationship; semi-empirical approach; sjötransport; PEM-bränsleceller; livslängdssimulering; nedbrytningsmekanism; empiriskt samband; semi-empiriskt tillvägagångssätt;

    Sammanfattning : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. LÄS MER

  3. 12. Dödens offentlighet, självmordets politik. Självmordet som ideologisk kamp i dagspressens notiser 1860–1900

    Master-uppsats,

    Författare :Dahlkvist Rebecka; [2021-09-21]
    Nyckelord :;

    Sammanfattning : Under 1800-talets sista decennier var självmord en självklar del av dagspressens rapportering. Det ägde rum mot bakgrund av en strukturell samhällsomvälvning samt en ideologisk drabbning mellan liberala, konservativa och socialister och en pågående förhandling om kulturella normer. LÄS MER

  4. 13. Decomposition of wage gap between matched natives and refugees in Germany

    Master-uppsats, Jönköping University/Internationella Handelshögskolan

    Författare :Qiuyu Yang; [2021]
    Nyckelord :wage gap; refugees; CEM; labour market integration;

    Sammanfattning : Prolonged and new regional violent conflicts have resulted in the displacement of residents in several countries. The thesis focuses on the people who arrived and applied for asylum in Germany between 2013 and 2016. LÄS MER

  5. 14. Investigation of the Effects of Invisible Neutrino Decay at the Proposed ESSnuSB Experiment

    Master-uppsats, KTH/Fysik

    Författare :Daniel Kempe; [2021]
    Nyckelord :Neutrino; Decay; Neutrino oscillations; Neutrino oscillation experiment; Neutrino; Sönderfall; Neutrinooscillationer; Neutrinooscillationsexperiment;

    Sammanfattning : This thesis studies neutrino oscillations at the proposed ESSnuSB experiment and the effects of invisible decay, where the neutrino mass states are assumed to be able to decay, on the planned measurements and the physics potential for this experiment to detect neutrino decays. This is accomplished by simulating a combined scenario of neutrino oscillations and invisible neutrino decay. LÄS MER

  7. 15. PlaCo : The plastic collecting robot

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Annie Persson; Johanna Bergsten; [2021]
    Nyckelord :Arduino; IR-sensor; marine debris; mechatronics; microplastics; ultrasonic sensor; Arduino; IR-sensor; marin nedskräpning; mekatronik; mikroplaster; ultraljudssensor;

    Sammanfattning : The oceans are an essential global resource for all living organisms but especially for us humans. However, year after year we continue to neglect proper recycling of our waste, resulting in litter ending up in our oceans. The majority of said litter comes from single use plastic items. LÄS MER
