  1. 1. 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

  3. 2. Making Sense of Material Culture : A Sensory Approach to Bird-Shaped Vessels in Imperial Age Greece

    Master-uppsats, Stockholms universitet/Antikens kultur och samhällsliv

    Författare :Lina Enevång Viklund; [2023]
    Nyckelord :bird-shaped vessels; glass unguentaria; ancient senses; archaeology of the senses; ancient lived experience;

    Sammanfattning : The focus of this thesis is Roman bird-shaped glass vessels from the 1 st and 2 nd centuries AD. The vessels were containers for cosmetics and distinguished themselves from other types of unguentaria in that once they had been filled with cosmetic powder, the vessels were reheated and sealed shut by fire.

  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. Permanent Fire Load of the Building Envelope

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Gizelle Danine Pondevida Jamero; [2023]
    Nyckelord :Permanent fire load; temporary fire load; fire load; building envelope; insulation; building content; upholstered furniture; heat of combustion; MCC; bomb calorimeter; cone calorimeter; room corner test.; Technology and Engineering;

    Sammanfattning : Fire load, the total thermal energy released by the combustion of a material, is an essential part of determining a building’s fire performance and the associated fire protection strategies. Elements in a structure are typically categorized into two types of fire loads: permanent and temporary. LÄS MER

  7. 5. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Elin Bergroth; Greta Torstensson; [2023]
    Nyckelord :Solar Photovoltaic; National Guidelines; Fire Department; FE-analysis; TASEF; Solceller; Nationella Riktlinjer; Räddningstjänst; FE-analys; TASEF;

    Sammanfattning : The global use of energy increases every day and to meet the growing demand, energy sources are constantly being developed to become more efficient and reliable. During the last decade, the global solar photovoltaics (PV) capacity has increased every year and in 2017, solar PV was the global leading power source of renewable energy. LÄS MER
