  1. 31. 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.

  3. 32. Validation of WUI-NITY compared to real-world data

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jonatan Edenvik; [2022]
    Nyckelord :Wildland urban interface; Wildfires; Community evacuation; Real-world simulation; WUI-NITY; PeMS; Pedestrian simulation; Traffic simulation; Technology and Engineering;

    Sammanfattning : This thesis compares the wildfire evacuation simulation programme, WUI-NITY, against real-world data by analysing and comparing three wildfire events of the past. The wildfire events were all limited to be within the state of California and was further analysed based on the available quality of data derived of the chosen database. LÄS MER

  4. 33. Verification Testing of Evacuationz, a Coarse Network Evacuation Model

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Antariksh Gupta; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Several evacuation models exist in the market. It is an issue for both the user and developer to evaluate the ease of use and the quality of the model results. Verification is the process of determining that the results of a calculation method match with the developer's conceptual modelling representation expectations, i.e. LÄS MER

  5. 34. Impact of Lecture Hall Layout on Evacuations Using Crowd Simulations

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Tobias Mattsson; Ernest Umeh; [2022]
    Nyckelord :Lecture hall; Evacuation; Simulation; Evacuation rate; Layout variation; Föreläsningssal; Evakuering; Simulation; Evakueringstakt; Layoutvariationer;

    Sammanfattning : The planning and preparation phases of emergency management are of great social interest. If appropriate safety measures can be implemented in buildings beforehand as a response to foreseeable hazards, the safety of individuals can be significantly increased. LÄS MER

  7. 35. Att få människor att utrymma vid ett dammbrott, svårare i praktiken än teorin? : Faktorer som påverkar en utrymning utifrån ett individ- och tjänstemannaperspektiv

    Master-uppsats, Karlstads universitet/Institutionen för samhälls- och kulturvetenskap (from 2013)

    Författare :Josefine Björnsdotter; [2022]
    Nyckelord :evacuation; dam failure; Protective Action Decision Model; Luleå municipality; individual perspective; risk perception.; utrymning; dammbrott; Protective Action Decision Model; Luleå kommun; individperspektiv; riskuppfattning.;

    Sammanfattning : Introduktion: Dammbrott är en olycka som har en låg sannolikhet att ske men om den skulle inträffa ha katastrofala konsekvenser. Ett område som skulle drabbas vid ett dammbrott i Luleälven är Luleå kommun som ligger i mynningen av Luleälven. LÄS MER
