  1. 1. Exploring the Feasibility of Using Fire Dynamics Simulator to Improve the Calculation of the Wildfire Available Safe Egress Time

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Alfred El Haddad; [2023]
    Keywords : Wildfire; Trigger buffer; WUI; WASET; FDS; QGIS; Level set; WUI evacuation.; Technology and Engineering;

    Abstract : Wildland-Urban Interface (WUI) fires pose a significant threat to public safety and property in areas where urban development encroaches upon natural landscapes. This thesis aims to investigate the effect of smoke from a WUI fire on the tenability conditions of a small village and to establish a worst-case-scenario trigger boundary around it as an improved basis for the WUI available safe egress time (WASET).

  3. 2. Finite Element Simulation of Moisture Transport in Cellulose Insulation Material of Power Transformers

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Luc Villibord; [2023]
    Keywords : ;

    Abstract : Power Transformers are an important and complex part of the electrical transmission technology. One of the main producers of these transformers worldwide is Hitachi Energy, for which this work has been done. READ MORE

  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. Visibility in Smoke With Different Extinction Coefficients

    University essay from Lunds universitet/Avdelningen för Brandteknik

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

    Abstract : 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.

  6. 5. Design and development of a submersible UAV

    University essay from KTH/Flygdynamik

    Author : Adam Olsson; [2021]
    Keywords : UAV; Drone; Submersible; VTOL;

    Abstract : Using autonomous underwater vehicles is a popular method of collecting samplesand conducting surveys, but the transportation of this information is not always easy.The underwater vehicle might be unable to transmit the information wirelessly, andsamples may be required to be transported a long distance.
