  1. 1. A scoping review and bibliometric analysis on juvenile fire setting behaviour

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Johanna Åkerström; [2024]
    Keywords : Juvenile; underage; fire setting; arson; Technology and Engineering;

    Abstract : The purpose of this review was to examine and analyse existing scientific literature on juvenile fire setting behaviour and to provide suggestions for future research. The PRISMA (Transparent Reporting of Systematic Reviews and Meta-Analysis) framework was used to search and collect relevant literature. READ MORE

  3. 2. Reconstruction of Fire Spread with a Markov Random Field Mixture Model

    University essay from Lunds universitet/Matematisk statistik

    Author : Marcus Gehrmann; [2023]
    Keywords : Forest fire; fire scars; spatial statistics; Markov random field; EM-algorithm; pseudo-likelihood; Mathematics and Statistics;

    Abstract : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

  4. 3. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Lorenzo Contini; [2022]
    Keywords : Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

    Abstract : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. READ MORE

  5. 4. Statistical analysis of firefighting and damage caused by fire in mid-rise timber-framed residential buildings compared to other construction types

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Thomas Berg; [2021]
    Keywords : Statistical analysis; timber-framed; residential; firefighting; damage caused by fire; PRONTO; NFID; linear regression; summary statistics; Technology and Engineering;

    Abstract : The contribution of greenhouse gas emissions in the production of construction materials has sparked a new interest and recent changes in building regulations regarding the use of renewables like wood as the main component in load-bearing elements. Recent regulation changes focus on allowing taller timber structures which bides the question of how to adequately maintain an acceptable level of fire protection considering the characteristically flammable properties of wood-based products.

  6. 5. The Analysis of Results of Stochastic Evacuation Models

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Erik Smedberg; [2019]
    Keywords : Evacuation; Fire safety; Behavioural uncertainty; Evacuation modelling; Evacuation simulation; Pathfinder; Functional analysis; Egress.; Technology and Engineering;

    Abstract : All humans are unique, we have different characteristics and we make different decision. This is a challenge when it comes to modelling human behaviour. The models we design are based on mathematics where there is no room for inconsistencies such that are present in human behaviour. READ MORE
