1. 16. The design of evacuation alarms for people who are deaf or hard of hearing

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

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

   Sammanfattning : 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. LÄS MER

3. 17. Time to ignition for wood covered with ZnO : A laboratory and theoretical study if ZnO can enhance time to ignition for wood exposed to radiation in the cone calorimeter

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Olina Öhrn; [2023]
   Nyckelord :ZnO; zinc oxide; cone calorimeter; wood; reaction-to-fire;

   Sammanfattning : In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. LÄS MER

4. 18. Flame Extensions Under Ceilings

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Martin Sturdy; [2023]
   Nyckelord :Flame length; curved ceiling; Technology and Engineering;

   Sammanfattning : In this Master thesis project the factors affecting flame extension under flat and curved ceilings have been investigated. An experimental campaign was carried out in Lund University’s Fire Lab using a propane gas burner and heptane pool fire in different positions and heat release rates within the setups. LÄS MER

5. 19. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Wickramasooriyage Devmini Kularatne; [2022]
   Nyckelord :Oriented strand board; thermal decomposition; mechanical degradation; heat transfer modelling; Technology and Engineering;

   Sammanfattning : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. LÄS MER

7. 20. Molns inverkan på satellitdetektion av vegetationsbränder i Sverige

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Marcus Letalick; [2022]
   Nyckelord :clouds; satellite detection; VIIRS; active fires; forest fire; grass fire; FRP; NOAA-20; Suomi-NPP; JPSS; moln; satellitdetektion; VIIRS; skogsbrand; gräsbrand; vegetationsbrand; FRP; NOAA-20; Suomi-NPP; JPSS;

   Sammanfattning : Results are presented from the 2021 test run of active fire detection using the Visual Infrared Imaging Radiometer Suite (VIIRS) instrument, that is currently onboard the polar satellites Suomi-NPP and NOAA-20. The test is performed by the Swedish Civil Contingencies Agency and the Swedish Meteorological and Hydrological Institute, in cooperation with local fire departments in Sweden. LÄS MER
