  1. 1. Short- and long-term survival rates after colic surgery : a retrospective study of colic horses operated at UDS between 2019-2022

    Master-uppsats, SLU/University Animal Hospital

    Författare :Fabian Förander; [2024]
    Nyckelord :colic; surgery; survival; complications; short-term; long-term;

    Sammanfattning : Colic can be a serious condition in horses, that may require surgery. In this study, survival after colic laparotomy was investigated both in the short-term (until discharge from the hospital) and in the long-term (until 1-year after surgery). Survival of different diagnoses found during surgery was explored. LÄS MER

  5. 4. 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.
