  1. 11. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

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

    Författare :Yudong Lin; [2023]
    Nyckelord :Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

    Sammanfattning : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. LÄS MER

  3. 12. Children’s education and parents’ mortality – Do parents with highly educated children live longer?

    Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Pauline Bode; [2023]
    Nyckelord :Mortality inequalities; socioeconomic gradient in health; children’s education; socioeconomic status; SES; demography; Business and Economics;

    Sammanfattning : While there exists a large literature on mortality inequalities by an individual’s level of education and other socioeconomic characteristics this thesis looks at the relationship between the children’s level of education and parents’ mortality, which has been relatively less studied. I use longitudinal data from the Survey of Health, Ageing and Retirement in Europe (SHARE) for the years 2004-2017 and conduct Cox proportional hazard regressions to assess how children’s level of education affects parents’ mortality risks.

  4. 13. Microstructural design and optimization of Nickel-based superalloys for gas turbines

    Master-uppsats, KTH/Materialvetenskap

    Författare :Anirudh Vasishta; [2023]
    Nyckelord :Nickel- based superalloys; gamma prime γ′ size calculations; Nickelbaserade superlegeringar; gamma prime γ′ storleksberäkningar;

    Sammanfattning : One of the main sources of energy in this modern world is the gas turbine.  They reach extremely high working temperatures at peak capacity and hence require materials that can withstand the same. LÄS MER

  5. 14. COVID-19: Healthcare Utilization Changes and Social Factors : A study on individuals aged over 50 in Europe

    Master-uppsats, Umeå universitet/Nationalekonomi

    Författare :Marios-Yordanis Popov; [2023]
    Nyckelord :;

    Sammanfattning : The thesis studies a sample of individuals over the age of 50 in Europe with the purpose of identifying any differences in healthcare utilization due to the COVID-19 pandemic. The main focus of the study is the impact that social factors have had on one’s behaviour and risk preferences, even if they themselves did not fall ill. LÄS MER

  7. 15. Prediction of dementia based on older adults’ sleep disturbances using machine learning: a controlled experiment.

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Joel Nyholm; [2023]
    Nyckelord :Dementia; Sleep; Risk factors; Machine learning;

    Sammanfattning : Background. Sleep disturbances can indicate an increased risk of dementia. This study examines whether machine learning can predict this association and which sleep disturbance factors impact dementia. Methods. LÄS MER
