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

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

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

   Sammanfattning : 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. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Lorenzo Contini; [2022]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Aktivitetsbaserade kontorslandskaps inverkan på utrymning

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Joel Hellbe; Ludvig Altesjö; [2018]
   Nyckelord :aktivitetsbaserat kontor; arbetsmiljö; utrymning; gruppbeteende vid utrymning; beslutsfattning; förberedelsetid; förflyttningstid; utrymningssimulering; activity based work; ABW; emergency egress; evacuation; group dynamic; pre movement time; Technology and Engineering;

   Sammanfattning : Aktivitetsbaserade kontor blir ett allt vanligare val av kontorsutformning bland dagens företag, är det av intresse att utreda vilken påverkan det har på utrymning. Det aktivitetsbaserade kontorskonceptet innebär att de traditionella fasta skrivbordsplatserna försvinner från kontoren. LÄS MER

5. 4. Retractable Boarding Step to Scania Crew Cab : Product Development, Design, FEM Simulations and Verification

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

   Författare :Nadine Möllberg; [2017]
   Nyckelord :Product development; FEM Simulations; Catia GAS; Boarding Step; Crew Cab; Scania CV AB; Produktutveckling; FEM Simulering; Catia GAS; Insteg; Crew Cab; Scania CV AB;

   Sammanfattning : This master thesis treats the development of a new solution for a retractable boarding step to Scania trucks, which is a part of the modular system. Some customers have the need to transport additional passengers. For such applications, Scania provides trucks featuring a Crew Cab, which is an extended cab with rear doors. LÄS MER

7. 5. A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Selenay Simsek; [2016]
   Nyckelord :Pedestrian movement; evacuation experiments; inter-person distance; fundamental diagram; Technology and Engineering;

   Sammanfattning : A Novel Way of Measuring Inter-Person Distance: A Study Involving an Ultrasonic Measurement Device The quantitative characteristics of people movement that form the fundamental diagram have an important role in the field of Fire Safety Engineering regarding evacuation. The fundamental diagram indicates the relation between crowd speed and crowd density (or inter-person distance) or flow of crowd and crowd density. LÄS MER
