  1. 21. Charging of aerosol particles - An investigation of the possibility of using Americium-241 for SMPS chargers

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Sofie Hansen; [2018]
    Nyckelord :SMPS; aerosol particles; Americium-241; climate change; particle number size distribution.; Earth and Environmental Sciences;

    Sammanfattning : Climate change is a fact and effects everybody on this planet, whether its humans, plants or animals. There is a comprehensive agreement about the mechanisms on how aerosol particles affect the radiative balance of the earth, but there is a need of more knowledge to fully understand climate change and the strength of the aerosol radiative forcing.

    Sammanfattning : Millimeter-wave radar imaging has potential uses in applications such as material analysis and medical in-vivo scanning of tissue. This thesis is about measuring objects using a millimeter wave radar, implement radar imaging algorithms and evaluate the resulting images. LÄS MER

  4. 23. Studie av ventilation i simhall : Med fokus på klorbaserade luftföroreningar

    Uppsats för yrkesexamina på grundnivå, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Mikael Dahlby; Robin Gustafson Sjöberg; [2017]
    Nyckelord :Ventilation; Air distribution; Public baths; CFD; Trichloramine; Ventilation; Luftföring; Simhall; CFD; Trikloramin;

    Sammanfattning : Allmänna bad bidrar i hög grad till att främja allmänhetens hälsa och välbefinnande. De erbjuder möjlighet till motion och rekreation för människor i alla åldrar. För att badgäster ska trivas och må bra krävs det att vatten- och luftkvalitet håller hög nivå. LÄS MER

  5. 24. Ventilation strategies for road tunnels in different countries and consequences using Fixed Fire Fighting System (FFFS)

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Rohan John Baptiste; [2017]
    Nyckelord :Longitudinal ventilation; fixed fire fighting system FFFS ; fractional effective dose FED ; Technology and Engineering;

    Sammanfattning : A study is carried out on the ventilation strategies for road tunnels in different countries and consequences using fixed fire fighting systems (FFFS). The type of ventilation strategy for road tunnels can ensure the safety of people during the evacuation stages and protection of the rescue services during their intervention of the fire. LÄS MER

  7. 25. Studies on the application of gas cooling as used by firefighters

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jan Bonnier; [2017]
    Nyckelord :Gas cooling; Firefighting; Fire Service; 3D-technique; Technology and Engineering;

    Sammanfattning : Gas cooling is a technique used by firefighters to create a safer work environment inside a compartment fire. By spraying water into the smoke layer, the smoke layer temperature will decrease significantly. Next to the lower temperature, the flammability of the smoke layer will also decrease. LÄS MER
