  1. 11. Comparing a full scale test with FDS, FireFOAM, McCaffrey & Eurocode

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

    Författare :Erik Edin; Mattias Ström; [2019]
    Nyckelord :FDS; FireFOAM; OpenFOAM; Performance-Based Design; Localized fire.;

    Sammanfattning : In the rapidly growing field of CFD-calculations (Computational Fluid Dynamics), companies and organizations are bringing forth new tools, tools that display an image of a given fire scenario. These tools are developed because they provide time efficiency as well as a sustainable economic approach. LÄS MER

  3. 12. HEART RATE RECOVERY IN EXHAUSTION DISORDER : quadratic vagal interaction predicting work ability?

    Magister-uppsats, Umeå universitet/Institutionen för psykologi

    Författare :Anna Sandgren; [2019]
    Nyckelord :Exhaustion disorder; ED; Burnout; Heart rate recovery; HRR; gastrointestinal; work ability; Exhaustion disorder; ED; Burnout; Heart rate recovery; HRR; gastrointestinal; work ability;

    Sammanfattning : Exhaustion disorder (ED) is a Swedish criteria-based medical diagnosis related to burnout, that often requires long term rehabilitation and sick leave. Comorbidity of functional gastrointestinal (GI) problems and ED has been reported and may be mediated by dysregulated vagal function. LÄS MER

  4. 13. Determination of design fires for cables

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Sompoom Soontara; [2016]
    Nyckelord :FIPEC; FIPECMATCH; Similarity; Matching; Mismatching; Heat release rate curve and Comparison.; Technology and Engineering;

    Sammanfattning : FIPECMATCH is a cloud computing software for matching the new HRR small-scale cable test to the HRR small-scale cable test of FIPEC’s database. This package works by setting up two HRR filters, which would be able to select the most similar HRR pattern stored in the FIPEC’s database. LÄS MER

  5. 14. Elevated Fires

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Kseniia Polukhina; [2016]
    Nyckelord :fire position; elevation; fire development; Technology and Engineering;

    Sammanfattning : The primary objective of the present study is to evaluate the effect of the fire source elevation on the main fire parameters, by implementing laboratory experiments. In modern Fire Safety Engineering practice, it is often assumed that fire always commences at the floor level. However, it is not always the case. LÄS MER

  7. 15. Brandrisker vid lägre syrehalter – Experiment i konkalorimetern

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Erik Linnå; Viktor Wahlström; [2014]
    Nyckelord :CACC; carbon dioxide; carbon monoxide; cone calorimeter; controlled atmosphere; fire risk; heat release; HRR; hypoxic air; mass loss rate; oxygen; particle board; time to ignition; brandrisk; effekt; effektutveckling; koldioxid; kolmonoxid; konkalorimeter; LTH; massavbrinningshastighet; spånskiva; syrehalt; tid till antändning; Technology and Engineering;

    Sammanfattning : This report has been conducted to examine the advantages and disadvantages of using an open system for experiments in the cone calorimeter with a vitiated air enclosure at low oxygen levels. Eight different experimental set-ups were conducted in which two were designed according to ISO 5660, i.e. the cone calorimeter in its standard configuration. LÄS MER
