  1. 6. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia

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

    Författare :Calum Kvernes Macpherson; [2023]
    Nyckelord :Bulge; Milky Way; Kinematics; Galpy; Dwarf Stars; Physics and Astronomy;

    Sammanfattning : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

  3. 7. Wind Turbine Recovery Forecasting using Survival Analysis

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Anton Palets; [2023]
    Nyckelord :Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

    Sammanfattning : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

  5. 9. The incidence of post-operative colic in adult equine patients undergoing elective non-abdominal surgery at SLU and potential risk factors

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Therése Åkesson; [2023]
    Nyckelord :post-operative colic; fasting; starvation; risk factors colic;

    Sammanfattning : Post-operative colic (POC) is a well-recognised complication in horses undergoing abdominal surgery but there are few studies describing the prevalence and incidence of colic in horses after non-abdominal surgery. Recently, the benefits of fasting horses pre-operatively have been questioned. LÄS MER

  7. 10. SWAT Runoff Modeling and Salinity Estimation in the Odra River Catchment

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi
