  1. 11. Analytisk dimensionering av brandsektioner

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

    Författare :Johannes Priebe; [2019]
    Nyckelord :Brandsektion; byggregler; brandvägg;

    Sammanfattning : Enligt Boverkets Byggregler 26 (BBR) kapitel 5:56 ska stora byggnader utformas så att omfattande brandspridning inom byggnaden begränsas. Det tillhörande allmänna rådet säger att detta bör uppfyllas genom att utforma byggnader med brandceller, brandsektioner, brandtekniska installationer eller en kombination av dessa. LÄS MER

  3. 12. Analysis of sustainable building materials, their possibilities and challenges

    Master-uppsats, KTH/Energiteknik

    Författare :Erik Arnesson; [2018]
    Nyckelord :;

    Sammanfattning : Sweden has as the first welfare state signed the petition of having net zero GHG emissions 2045. The construction industry is a large contributor to Sweden’s current GHG emissions and an action plan signed by several construction companies, including Veidekke, has stated several partial goals and one end goal of a construction industry with net zero emissions 2045.

  4. 13. A study to understand the information gap between total organofluorine analysis and total oxidizable precursor assay on polyfluoroalkyl/perfluoroalkyl substances (PFASs)

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Pontus Larsson; [2018]
    Nyckelord :;

    Sammanfattning : Total oxidizable precursor (TOP) assay is an oxidation method to convert precursor compound of polyfluoroalkyl/perfluoroalkyl substances (PFASs) into measurable perfluorinated carboxylic acids (PFCAs). A previous mass balance study has shown that a loss of fluorine was observed after employing the method to convert the precursors in firefighting foams. LÄS MER

  5. 14. CFD-simulations of urea-waterspray in an after-treatment systemusing Star-CCM+

    Master-uppsats, KTH/Mekanik

    Författare :Emelie Trigell; [2018]
    Nyckelord :after-treatment systems; selective catalytic reaction SCR ; AdBlue; multiphase flow; multi-component liquid; Unsteady Reynolds Average Navier Stokes RANS ; wall film formation; solid deposits; efterbehandlingssystem; selektiva katalytiska reaktioner; AdBlue; flerfasstr ¨ommning; flerkomponentvätska; Unsteady Reynolds Average Navier Stokes; väggfilm; avlagringar;

    Sammanfattning : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. LÄS MER

  7. 15. Flashing lights at road tunnel emergency exit portals: A Virtual Reality study with low-cost Head Mounted Displays

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :David Mayorga; [2017]
    Nyckelord :Virtual Reality; Cross comparison; Head Mounted Displays; Theory of Affordances; Flashing Lights; Road Tunnels; Technology and Engineering;

    Sammanfattning : Previous studies have provided detailed recommendations regarding the design of flashing lights at emergency exit portals in road tunnels. Theory of Affordances have assisted safety designers fixing characteristics such as color, flashing rate, type and number of lights in emergency systems. LÄS MER
