  1. 1. SAKTA NER ELLER SKROLLA VIDARE? En studie av användarna på TikTok om sin upplevelse av korta medieformat och dess påverkan

    Kandidat-uppsats, Göteborgs universitet/Institutionen för journalistik, medier och kommunikation

    Författare :Alana Cornéer; [2024-03-04]
    Nyckelord :TikTok; koncentrationsförmåga; uppmärksamhet; korta medieformat;

    Sammanfattning : This study delves into the user experiences and perceptions of short media formats on TikTok and their impact on users' attention spans. Drawing from theoretical frameworks such as attention theory, media ecology, and uses and gratifications theory, the study conducted qualitative interviews with six participants to delve deeper into their experiences.

  3. 2. Utvärdering av tunnelbrandsmodeller

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Johanna Gondinger; Alva Larsson; [2024]
    Nyckelord :Tunnelbränder; FDS; handberäkning; branddynamik; brandexperiment Tunnel fires; CFD; hand calculations; fire dynamics; fire experiment; Technology and Engineering;

    Sammanfattning : The purpose of this study was to investigate the predictive capabilities of hand-calculation methods and simulations using FDS in understanding the behavior of a tunnel fire in terms of temperature and incident radiation. Additionally, the study aimed to examine the repeatability of a large-scale fire experiment. LÄS MER

  4. 3. Comparing energy efficiency of Leaky integrate-and-fire and Spike response neuron models in Spiking Neural Networks

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Majd Dawli; Imran Bahed Diva; [2023]
    Nyckelord :;

    Sammanfattning : Spiking Neural Networks (SNNs) are a type of neural network that is designed to mimic the way neurons function in our brains. While there have been notable advancements in developing SNNs, energy consumption hasn't been studied to the same extent. This gets especially relevant with steadily increasing network sizes.

  5. 4. Validering av FDS för simulering av mindre vätgasläckage inomhus

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Emil Hamnes Alavei; Erik Andersson; [2023]
    Nyckelord :Hydrogen; Helium; Ventilation; CFD; FDS; Technology and Engineering;

    Sammanfattning : The prevailing global climate transition is incentivized to occur in a short period of time. Hydrogen is considered a pivotal element towards a renewable energy system. However, the physical and chemical properties of hydrogen give rise to the risk of fire and explosion. LÄS MER

  7. 5. Exploring the factors affecting tree establishment after wildfire in a boreal forest in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Robert Pim; [2023]
    Nyckelord :tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Sammanfattning : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. LÄS MER
