  1. 1. Pricing and Modeling Heavy Tailed Reinsurance Treaties - A Pricing Application to Risk XL Contracts

    Master-uppsats, KTH/Matematisk statistik

    Författare :Ormia Abdullah Mohamad; Anna Westin; [2023]
    Nyckelord :Reinsurance; Extreme Value Theory; POT-model; Hill estimator; Risk XL contracts; Generalized Pareto distribution; Method of Moments.; Återförsäkring; Extremevärdesteori; POT-modellen; Hill estimatorn; Risk XL kontrakt; generella Paretofördelningen; Momentmetoden.;

    Sammanfattning : To estimate the risk of a loss occurring for insurance takers is a difficult task in the insurance industry. It is an even more difficult task to price the risk for reinsurance companies which insures the primary insurers. LÄS MER

  3. 2. Våtmarkers relation till skogsbränder : En litteraturstudie och GIS-analys av intakta och utdikade våtmarker i borealt svenskt skogslandskap

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Rufus Rune; Emilia Tidblad; [2023]
    Nyckelord :wetland; wildfire; peat; fire spread; GIS; drainage; våtmark; skogsbrand; torv; brandspridning; GIS; utdikning;

    Sammanfattning : Som en följd av global uppvärmning blir det allt viktigare med resiliens mot klimatkrisens konsekvenser, däribland mer frekventa skogsbränder. Då våtmarker kan behålla vatten och ge resiliens mot torka och bränder är det intressant att undersöka relationen mellan våtmarker och skogsbränder. LÄS MER

  4. 3. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :David Aronsson Edström; Oskar Lundberg; [2022]
    Nyckelord :3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Sammanfattning : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. LÄS MER

  5. 4. Standardiserad kvalitetssäkring av brandskydd i BIM

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Mathias Undeland; Oliwer Warnerfelt; [2022]
    Nyckelord :BIM; Byggnadsinformationsmodellering; Solibri Office; Solibri Model Checker; SMC; brandprojektering; digital projektering; kvalitetskontroll; kvalitetssäkring; BIMfire Tools.; Technology and Engineering;

    Sammanfattning : Digitized workflows are becoming more common in the construction industry where building information modeling, also called BIM, is a common example of this development. The BIM environment enables an unbroken chain of information on a corporate platform. LÄS MER

  7. 5. Visibility in Smoke With Different Extinction Coefficients

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Lea Elhokayem; [2022]
    Nyckelord :Visibility; smoke; exit sign; extinction coefficient; visibility constant; evacuation; Technology and Engineering;

    Sammanfattning : Visibility in smoke has since the 1970s gained some attention, mostly after Tadahisa Jin ran the experiments which helped him develop todays widely used visibility equation. By showing that visibility can be assumed to be inversely proportional to the extinction coefficient by a visibility constant (equal to 8 for light emitting sign and 3 for light reflecting), Jin opened up new doors for researchers who were testing out his theory by going around experimenting in different ways and also by showing that there is way for more research to be done.
