  1. 6. Investigation on Enhancing Fire Threat Perception in Virtual Reality through Subject-Expectancy Effect

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Hsuan-Ting Liu; [2023]
    Keywords : Virtual reality; safe distance; subject-expectancy effect; thermal radiation; placebo effect; fire scenario.; Technology and Engineering;

    Abstract : This thesis examines the use of subject-expectancy effect on enhancing fire threat perception in virtual reality. The study involves a virtual fire scenario design and 33 participants who experience virtual fires of three different scales in the scenario using a head-mounted display as visual and auditory perception and adopting physical movement in real world as their way of locomotion.

  3. 7. 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).

  4. 8. Suppression of Li-ion Battery Fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Linfan Cai; [2023]
    Keywords : Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

    Abstract : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

  6. 10. The design of evacuation alarms for people who are deaf or hard of hearing

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Anastasia Afanasova; [2023]
    Keywords : Alarm system; Deaf people; Hard-of-hearing people; Fire safety.; Technology and Engineering;

    Abstract : The ability to hear is essential for receiving auditory signals, which serve as warnings and alerts in many situations, including fire evacuation. However, people with hearing impairments may miss out such signals and can be exposed to dangerous situations. READ MORE
