  1. 16. Satellite signal attenuation due to atmospheric influences in northern Sweden

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Adrian Stigsson; [2024]
    Nyckelord :;

    Sammanfattning : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. LÄS MER

  3. 17. Beständigheten hos brandimpregnerat trä

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Filip Engström; Hannes Psajd; [2024]
    Nyckelord :Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

    Sammanfattning : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

  4. 18. Torkstress hos urbana träd i Göteborg: Effekter av låg vattentillgång under torkan 2018

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Andrea Sartorius; [2023-10-27]
    Nyckelord :;

    Sammanfattning : During late spring and most of the summer in the year of 2018 the weather in Sweden was more extreme than normal, with high temperatures and few rainfalls. This resulted in a drought, of which the effects were noticed all over the country. One of the noticeable effects was an earlier leaf abscission from trees. LÄS MER

  5. 19. CNN-LSTM architecture for predicting hazardous driving situations

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Noomi Lindblad; Stefani Platakidou; [2023-10-05]
    Nyckelord :Data science; Machine learning; LSTM; CNN; Vehicle data; Hazardous driving situation; Deep learning;

    Sammanfattning : This study aims to investigate how a CNN-LSTM model can be used together with recorded vehicle data from trucks and external weather data in order to predict a hazardous driving situation. The dataset consists of three-second-long driving snippets from customer and development trucks registered within Europe. LÄS MER

  7. 20. Uncertainties in characterising historical heatwaves in Europe

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Simon Abrahamsson; [2023-08-18]
    Nyckelord :;

    Sammanfattning : Heatwaves are periods of excessively hot weather which can pose a threat to both the people and the agriculture affected by them, for this reason it is important for us to understand and be able to predict heatwaves. This study will therefore investigate historical heatwaves in Europe and compare the quality of different 2m surface temperature datasets and examine the possibility of using 3D temperature data to identify heatwaves.
