1. 21. Genetic Algorithms for optimizing behavior trees in air combat

   Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

   Författare :David Ångström; [2022]
   Nyckelord :Genetic Algorithm; Behavior Tree; Behavior Model; Simulation; Optimization;

   Sammanfattning : Modelling and simulating entities in virtual environments are tools commonly used by companies to test, validate and verify their products in close to real scenarios; effectivelyreducing the cost, time and effort compared to real life testing. This is especially the case in the area of air combat where realistic behaviors are not only a necessity, but paramount to replace the costs of fuel and operation time. LÄS MER

3. 22. 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. 23. Flow batteries - Impact on fire safety

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Ajay Menon; [2022]
   Nyckelord :Flow battery; Flow battery types; Flow battery risks; Firefighting; Fire risk analysis; Safety hazards in flow batteries; Fire risks in lithium-ion battery; Safety hazard in lithium-ion battery; Application of battery storage systems; Safety reports.; Technology and Engineering;

   Sammanfattning : The need for sustainable renewable energy has been increasing due to the negative impact of non-renewable energy sources. With the unstable and sporadic nature of sustainable renewable energy, flow batteries show immense potential in mitigating these issues. LÄS MER

5. 24. Visibility in Smoke With Different Extinction Coefficients

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

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

   Sammanfattning : 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.

7. 25. Simulation of standing versus crawling during evacuation from a smoke-filled room

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :David Bergendorff; Jonas Lundin; [2021]
   Nyckelord :;

   Sammanfattning : Crawling is often the recommended method when evacuating from a burning room. In this study, an agent based crowd simulation in combination with a fire dynamics simulator is used in order to compare how well crawling evacuation compares to a standing type of evacuation. LÄS MER
