1. 1. Determination of Material Properties for Fire Modelling

   Författare :Ulf Göransson; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material properties; Material degradation; Measurements; Fire test data; Byggnadsteknik; Building construction; Teknik; Technological sciences; Fire; Surface temperature; Mathematical modelling;

   Sammanfattning : Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. LÄS MER

3. 2. The Development of a European Fire Classification System for Building Products - Test Methods and Mathematical Modelling

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; Teknik; Technological sciences; Brandteknik; Fire Protection Engineering; Conflame; Cone Tools; FDS; CFD; Duhamel?s integral; Fire Growth Rate; FIGRA; Euroclass; SBI; Single Burning Item; Cone Calorimeter; Room Corner Test; fire modelling; Reaction to fire; flashover;

   Sammanfattning : The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. LÄS MER

4. 3. Fire behaviour of upholstered furniture component materials at multiple scales

   Författare :Konrad Wilkens Flecknoe-Brown; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; upholstered furniture; Polyurethane; Scaling; Experimental; Modeling; fabric;

   Sammanfattning : In this research, both experimental test methods and computer models were used to characterise the thermal decomposition processes of selected upholstered furniture component materials, namely; flexible polyurethane foam and a range of different fabric coverings. This was first done at some of the smallest, simplest levels available, and how these materials were tested and the methods chosen to investigate them, was examined. LÄS MER

5. 4. Multi-Agent Potential Field based Architectures for Real-Time Strategy Game Bots

   Författare :Johan Hagelbäck; Stefan J. Johan; Pieter Spronck; Blekinge Tekniska Högskola; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; real-time strategy; potential fields; multi-agent systems; emergent behavior; Computer Science; Datavetenskap; Games; Real-Time Strategy; Potential Fields; Multi-Agent Systems;

   Sammanfattning : Real-Time Strategy (RTS) is a sub-genre of strategy games which is running in real-time, typically in a war setting. The player uses workers to gather resources, which in turn are used for creating new buildings, training combat units, build upgrades and do research. The game is won when all buildings of the opponent(s) have been destroyed. LÄS MER

7. 5. Lithium-ion Battery Safety - Assessment by Abuse Testing, Fluoride Gas Emissions and Fire Propagation

   Författare :Carl Fredrik Larsson; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; fire; thermal runaway; gas emission; gas explosion; propagation; safety; abuse testing; Lithium-ion; cell case explosion; hydrogen fluoride;

   Sammanfattning : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.
