  1. 16. Clearcutting and the breeding productivity of golden eagles (Aquila chrysaetos) in Västerbotten County

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Amanda Trulsson; [2019]
    Nyckelord :forestry; breeding productivity; breeding success; nestlings; breeding core home range; breeding core area;

    Sammanfattning : The golden eagle (Aquila chrysaetos) is red-listed as near threatened in Sweden, but there are many basic ecological and demographical parameters important for successful management and conservation that are unknown for the Swedish golden eagle population. Forestry, and especially clearcutting (or final cutting/felling or regeneration cutting/felling), the most common harvesting system in Sweden since the 1950’s, are likely important factors affecting the Swedish golden eagle population, but exactly how is largely unknown.

  2. 17. Rainfall Variation and Food Security in Malawi : A Panel Data Study with Valuable Insights from the Field

    Kandidat-uppsats, Uppsala universitet/Nationalekonomiska institutionen

    Författare :Klara Elzvik Nyström; [2019]
    Nyckelord :Food Security; Consumption Smoothing; Adaptation; Resilience; Climate Change;

    Sammanfattning : This study addresses the question of how climate variability, in terms of seasonal rainfall variation, might affect food security in Malawi. It hypothesizes that seasonal rainfall variation could cause food insecurity and that the consequences of weather hazards possibly differ within the country. LÄS MER

  3. 18. Individualized closed-loop anesthesia through patient model partitioning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Ylva Wahlquist; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master thesis project proposes methods for individualizing closed-loop controlled anesthesia. One of the largest challenges with closed-loop anesthesia is the variation between patients in the sensitivity to the anesthetic drug, here propofol. LÄS MER

  4. 19. Heart rate variability for driver sleepiness assessment

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Anna Persson; [2019]
    Nyckelord :Heart rate variability; sleepiness; drowsiness; fatigue; driver sleepiness; Hjärtfrekvensvariabilitet; sömnighet; trötthet; bilförare;

    Sammanfattning : Studies have reported that around 20 % of all traffic accidents are caused by a sleepy driver. Sleepy driving has been compared to drunk driving. A sleepy driver is also an issue in the case of automated vehicles in the future. Handing back the control of the vehicle to a sleepy driver is a serious risk. LÄS MER

  5. 20. Rank-Based Selection Strategies for Forecast Combinations: An Evaluation Study

    Magister-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Magnus Svensson; [2019]
    Nyckelord :time series forecasting; combining forecasts; forecast combination; M3-Competition; forecast accuracy; evaluation study; model confidence set; Mathematics and Statistics;

    Sammanfattning : This thesis evaluates four of the most popular methods for combining time series forecasts. One aspect that is often overlooked in the literature is the choice of which forecasts to include in a forecast combination. LÄS MER
