  1. 6. Exchange Rate Analysis Between the U.S. Dollar and the Japanese Yen

    Kandidat-uppsats, Uppsala universitet/Statistik, AI och data science

    Författare :Yuta Sakiyama; [2023]
    Nyckelord :;

    Sammanfattning : The exchange data between the U.S. Dollar and Japanese Yen are analyzed with three models called the Auto-Regressive Integrated Moving- Average (ARIMA) model, the Generalized Auto-Regressive Conditional Heteroscedastic (GARCH) model, and the Fractional Differencing model.

  3. 7. Influence of structural complexity of the Rumperöd forest on evapotranspiration

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Madeleine Durdek; [2023]
    Nyckelord :Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

    Sammanfattning : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. LÄS MER

    Sammanfattning : Buttle Änge and Nygårds has been excavated by Uppsala University, Campus Gotland and also by Högskolan on Gotland since year 2009 and by Gothenburg University year 2009 and 2013. During the 20 excavations that has taken place there has been 112 glass beads found. LÄS MER

  5. 9. Body weight, body condition and structural size of Scandinavian wolves

    Master-uppsats, SLU/Dept. of Ecology

    Författare :My Strömgren; [2023]
    Nyckelord :age; Canis lupus; food availability; inbreeding; natal territory; season; sex; wolf density;

    Sammanfattning : Large carnivours are suffering from population declines all over the world, but many have also recolonized parts of their previous habitats. However, recovery by these species is usually slow and challenging. LÄS MER

  7. 10. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Elias Aretorn; [2023]
    Nyckelord :CNG; Natural Gas; Heavy-Duty Vehicles; Fuel System; Contamination; Cleanliness; Accelerated Testing; Experimental Setup; Pressure Regulator;

    Sammanfattning : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. LÄS MER
