1. 16. Effects of soil factors on pioneer bryophyte species composition

   University essay from Lunds universitet/Examensarbeten i biologi

   Author : Dora Mijić; [2023]
   Keywords : Biology and Life Sciences;

   Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

3. 17. 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. 18. 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.

5. 19. Reconstruction of Fire Spread with a Markov Random Field Mixture Model

   University essay from Lunds universitet/Matematisk statistik

   Author : Marcus Gehrmann; [2023]
   Keywords : Forest fire; fire scars; spatial statistics; Markov random field; EM-algorithm; pseudo-likelihood; Mathematics and Statistics;

   Abstract : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

6. 20. Climate, Conflict, and Fire: Examining Correlations and Fire Indicators in Manisa and Diyarbakir, Turkey

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Christina Elena Albus; [2023]
   Keywords : Geopolitics; Vegetation fires; Armed conflict; Earth observation; Kurdistan; PKK; Turkey; Earth and Environmental Sciences;

   Abstract : Climate issues are currently of attention in various contexts as changing climate factors affect us in many ways. One of these effects is the influence on the probability and frequency of fires, although other factors, especially anthropogenic ones, also play a role. READ MORE
